Conference paper (peer-reviewed)abstract
- Urbanization is one of the major current trends in society. Cities around the world are looking into 'smart' solutions based on information and communication technology to deal with the challenges that result from this development. Mobility is one of the most important areas to address, and system-of-systems solutions where vehicles and infrastructure are connected have a potential to improve urban transportation in many aspects. In this paper, current initiatives related to mobility in smart cities around the world are surveyed, and this is complemented with input from focus groups of transportation stakeholders to identify the important aspects of the problem. Based on this, challenges related to the application of systems-ofsystems in urban mobility are identified.

Do i remember you? : Memory and identity in multiple embodiments
- 2013
-
In: Proceedings - IEEE International Workshop on Robot and Human Interactive Communication. - 9781479905072 ; , s. 143-148
-
Conference paper (peer-reviewed)abstract
- This paper investigates user perceptions of continuous identity as agents migrate between different embodiments. It reports an experiment seeking to establish whether migrating or not migrating the interaction memory of the agent would affect the user's perception of consistent agent identity over different embodiments. The experiment involved a treasure hunt in which a virtual agent migrated from a screen to a mobile phone in order to accompany a user while they searched for clues. A total of 45 subjects took part in three different conditions with 15 subjects in each. The outcome showed that the presence of memory affected the competence users ascribed to the virtual agent. However it had no significant effect on a strong perception of consistent identity across multiple embodiments.

Dialing for Displays: Session Initiation Protocol for Opportunistic Augmentation
- 2006. - 1
-
Conference paper (peer-reviewed)abstract
- Opportunistic augmentation denotes connecting a personal mobile device to another device to gain a transient advantage for the user. For example, a mobile phone user might borrow a large display and keyboard from a desktop personal computer. This uniquely ubiquitous computing activity requires effective device and service discovery as well as appropriate media usable across two or more devices. In this paper we show how Session Initiation Protocol (SIP), the call signaling protocol for Voice over IP, effectively separates discovery from media-rendering selection in opportunistic augmentation. This separation improves system flexibility while allowing users or system administrators to choose the most appropriate discovery technologies for the environment. We also describe two phone-centric discovery mechanisms and demonstrate the practicality of the system by implementation and use in a test environment.

Models and Tools for Distributed User Interface Development
- 2012
-
Licentiate thesis (other academic/artistic)abstract
- The way we interact with computers and computer systems are constantly changing as technology evolves. A current trend is that users interact with multiple andinterconnected devices on a daily basis. They are beginning to request ways and means of dividing and spreading their applications acrossthese devices.Distributed user interfaces (DUIs) have been proposed as a means ofdistributing programs over multiple interconnected devices through theuser interface (UI). DUIs represent a fundamental change foruser-interface design, enabling new ways of developing distributedsystems that, for instance, support runtime reorganization ofUIs. However developing DUIs presents a far more complex task compared totraditional UI development, due to the inherent complexity thatarises from combining UI development with distributed systems. Thetraditional approach in software engineering and computer science toovercoming complexity is to build tools and frameworks, to allowfor good code reuse and higher level of abstraction for applicationprogramers.Conventional GUI programming tools and frameworks are not developedto support DUIs specifically. In this thesis we explore key issues increating new programming tools and frameworks (APIs) for DUI-based UIdevelopment. We also present and discuss the DUI framework Marve,which adds DUI support to Java Swing.A unique feature of Marve is that it is designedfor industrial-scale development, extending a standard UIframework. The framework has beentested and evaluated in a project where an operator control stationsystem was developed.

Human papillomavirus in sinonasal inverted papilloma, recurrent respiratory papilloma and non-malignant tonsils
- 2019
-
Doctoral thesis (other academic/artistic)abstract
- Background: Human papillomavirus (HPV) is known to cause recurrent respiratory papilloma (RRP) and certain types of oropharyngeal cancer. HPV has also been associated with sinonasal inverted papilloma (SIP). HPV transmission routes are under investigation and the conviction is that the infection occurs sexually at an adult stage, however, vertical transmission at birth with a dormant viral condition until disease eruption/co-activation has been stated as a possibility.Purpose: The purpose of this work was to contribute to the understanding of HPV related chronic diseases in the airway. Specific aims were: 1. To increase understanding regarding changes in the immune system as well as of the glycosaminoglycan hyaluronan in patients with RRP. 2. To evaluate prevalence of HPV and its surrogate marker p16 in SIP as well as HPV, p16 and Epstein-Barr virus (EBV) in benign tonsillar disease. HPV and EBV in non-malignant tonsillar disease were studied due to the fact that incidence of HPV positive tonsillar cancer is increasing and the time of viral infection is unknown.Methods: A phenotypic characterization of peripheral blood from 16 RRP patients and 12 age-matched controls, using immunoflow cytometry, and monoclonal antibodies against differentiation and activation markers, was performed. The cytokine mRNA profile of monocytes, T helper-, T cytotoxic-, and NK cells was assessed using RT-qPCR. 54 SIP samples were studied of which 53 were available for analyzation with PCR. Genotype screening for 18 high risk and six low risk HPV types was performed using the PapilloCheck® HPV-screening test (a PCR method). 54 samples were immunohistochemically (IHC) stained for p16. Biopsies from vocal folds (VFs) and false vocal folds (FVFs) were collected from 24 patients with RRP, 12 were randomly selected to histochemistry for Hyaluronan (HA) and IHC staining for CD44 in the epithelium, stroma and RRP lesions. The remaining 12 patients were analyzed for HA molecular mass distribution with a gas-phase electrophoretic molecular mobility analyzer (GEMMA). Eight VF samples and four FVF samples were successfully analyzed. Biopsies from 40 non-malignant tonsils were analyzed using Papillocheck® for HPV, IHC for p16 and EBER analysis for EBV.Results: We found a dominance of cytotoxic T cells, activated NK cells, and high numbers of stressed MIC A/B (MHC class I chain-related molecule A/B) expressing lymphocytes. The HPV analysis was successful for 38 SIP samples and two (5%) were positive for HPV 11. Notably, p16 was present in the epithelia of all samples and in the papilloma portions in 37 of 38 samples. We found extensive HA staining in the stroma of both VFs and FVFs. CD44 was expressed throughout the epithelium, stroma, and RRP lesions in both FVFs and VFs, it did however, not concur with the expression of HA. Very high mass HA was found in both VFs and FVFs, though more variation regarding amounts of HA was seen in the VFs compared to FVFs. No HPV was found in non-malignant tonsils, the p16 levels were low and the counted EBER positive cells showed great variation in numbers.Conclusions: Our findings demonstrate an immune dysregulation with inverted CD4+/CD8+ ratio and aberrant cytokine mRNA production in RRP patients, compared to healthy controls. We concluded that p16 cannot be used as a surrogate marker for high-risk HPV-infection in SIP and that HPV incidence was low (5%). CD44 does not seem to bind to HA, which might explain the noninflammatory response previously described in RRP. Very high mass HA possibly crosslinked was seen in both VFs and FVFs. A possibility to counteract inflammatory crosslinking of HA may be found for medical treatment options in RRP.

Always-On + Adoption – a method for longitudinal studies
- 2012. - 5
-
Conference paper (peer-reviewed)abstract
- We will discuss an approach for conducting long term studies of companionship technologies – technologies intended for more intimate relationships with people. We draw from our work of conducting several qualitative long-term user studies of people’s relationship with robotic companions and mobile devices in order to develop a methodology where the initial bond with the artifact is based on a more intense experience. After this initial phase referred to as Always On the relationship will fade over to the adoption phase where the more traditional long-term use can be studied. Most recently we are trying out this approach for studying people’s experience of an online social game that features virtual agents.

Usability in Mobile IT systems
- 2005
-
Reports (pop. science, debate, etc.)abstract
- In this report we give an overview of usability aspects applicable to mobile devices and systems. A number of research projects from three different application areas are presented and experiences from the projects are discussed.To successfully design usable products, services and systems both for leisure and for mobile work practice has turned out to be a difficult undertaking. Many systems fail because of a number of reasons. Some systems do not fail, but remains difficult and cumbersome to use.A certain immaturity can be observed since developers and designers do not fully utilise the benefits and assets provided by today’s technology in design of mobile systems. For mobile systems, the varying contexts of use become more important. When only relying on existing knowledge of design for stationary systems, important possibilities are often lost and the system has gone astray.

Beyond Speculative Ethics in HRI? Ethical Considerations and the Relation to Empirical Data
- 2011. - 7
-
Conference paper (peer-reviewed)abstract
- We discuss the difference between understanding robot ethics as something that is grounded in philosophical ideas about a potential future design, and understanding robot ethics as something that is grounded in empirical data. We argue, that understanding “robots” as a relatively homogenous group of designs for which we can formulate general ethics may lead to a foresight of future robot designs that includes ideas and concerns that are not feasible or realistic. Our aim is to exemplify a complementing perspective, by shedding light on two different robotic designs. We discuss their relation to specific use practices and user experiences, and provide some early ethical reflections and design concerns.

Human papillomavirus in recurrent respiratory papillomatosis, tonsillar and mobile tongue cancer
- 2016
-
Doctoral thesis (other academic/artistic)abstract
- This thesis focuses on the effects of the human papillomavirus (HPV) in tonsillar cancer, mobile tongue cancer, and recurrent respiratory papillomatosis (RRP). The purpose was to characterize patients with RRP in northern Sweden in order to identify more care-intensive RRP patients and to describe the voice and quality of life aspects that follow RRP. Further aims were to confirm the expected increase of HPV-positive tonsillar cancer cases in northern Sweden, and to study the correlation between HPV, its surrogate marker p16 and HPV receptor syndecan-1 in both tonsillar cancer and mobile tongue cancer.A total of 27 consecutive patients with RRP were evaluated at 3 months postoperatively using the voice handicap index (VHI) and SF-36 questionnaires to assess the impact on life and voice in a RRP population. The values were compared to normative data. This report was further extended by examining consecutive data from 21 new patients in order to characterize RRP patients in northern Sweden. In order to study HPV DNA in tonsillar (n= 65) and mobile tongue cancer (n=109), HPV DNA was extracted from paraffin-embedded biopsies and detected by polymerase chain reaction using general primers Gp5+/6+ and CpI/IIG. Expression of HPV surrogate marker p16 and the HPV receptor syndecan-1 was analysed by immunohistochemistry.Patients that underwent more than one RRP surgery per year were younger than those treated less frequently and they had significantly impaired voice quality as compared to normal subjects. Females, patients with frequent surgical treatment sessions, and patients with the high-risk HPV subtypes scored significantly lower in several domains of the quality of life assessment as compared with normal subjects. Forty-eight RRP patients had a median age of 44.5 years; 71% were men and 29% females, preferentially infected with HPV6. Patients with high surgical treatment frequency/year showed more widespread RRP in the larynx compared to the patients treated less frequently.A total of 214 tonsillar cancer cases were identified. The vast majority were men. They had a median age of 58 years at diagnosis and expressed HPV as well as p16. The incidence of tonsillar cancer revealed a 2,7-fold increase in men between the years 1990 and 2013. The study demonstrates a strong association between p16 and HPV infection in tonsillar malignancies. These findings are in contrast to the mobile tongue cancer cases, where no evidence of HPV DNA could be detected although one-third showed p16 staining. This demonstrated a poor correlation between HPV and p16 in mobile tongue cancer. There was no difference in the expression of the primary HPV receptor, syndecan-1, between tonsillar and mobile tongue cancer.In conclusion, the frequency of RRP operations, age at onset, gender and subtype of the HPV may be used as factors to predict voice disability. RRP patients with high surgical treatment frequency were significantly younger and had a more widespread laryngeal disease compared to the low-frequency treated group. This study confirms the existence of a clinical RRP group, not primarily related to HPV subtype, but to a more care-intensive RRP population. Our findings identify a 2,7-fold increase in the incidence of tonsillar cancer, HPV and p16 in men between 1990-2013. We can use p16 to detect HPV in tonsillar cancer but not in tongue cancer.The introduction of vaccination against HPV may have a role in the prevention of specific HPV-subtype positive head and neck malignancies and recurrent respiratory papillomatosis since the current vaccine protects against HPV6, 11, 16, 18, 31, 33, 45, 52 and 58. Males will definitely benefit indirectly from vaccination of females, though males will still remain at risk of cancers associated with HPV. This highlights the need for sex-neutral vaccination strategy. Our intention is that this thesis will provide scientific data to support a gender-neutral vaccination and to develop simple tools to detect HPV in tonsillar cancer.

Adolescent behavior : Links to early-life stress and alcohol in male and female rats
- 2020
-
Doctoral thesis (other academic/artistic)abstract
- Adolescence is an important developmental phase with large changes in behavior, physiology and neurobiology, which transform an individual from immature child to independent adult. Due to these changes, adolescence is a sensitive period for exposure to environmental factors such as stress and drug exposure; it is also a common age of onset for alcohol consumption as well as several psychiatric disorders. Despite these factors, less is known about this developmental period than regarding adult individuals. Behavior is regulated by the central nervous system and can be used as a lens to study these processes as well as for examination of associations between individual differences, early-life stress and alcohol. The aim of this thesis was to experimentally examine adolescent behavior and its links to early-life stress and alcohol in adolescent male and female rats. Different behavioral tests were used to profile adolescent animals together with animal models of early-life stress, voluntary alcohol consumption and alcohol exposure. In addition, stress responsiveness after early-life stress and the impact of alcohol exposure on endogenous opioid peptide levels as well as blood alcohol concentrations were examined. The adolescent behavioral profile in the multivariate concentric square field™ (MCSF) was characterized and validated against the elevated plus maze and open field tests. The main finding was subgroups based on individual variation that revealed three distinct behavioral types: Explorers, Shelter seekers and Main type animals. This pattern was replicated in an additional, independent cohort. Early-life stress, modelled by prolonged maternal separation, showed small effects on behavior in the MCSF and on social play behavior. However, an effect on stress responsiveness in males but not females subjected to prolonged maternal separation was discovered. Predisposition for high alcohol consumption did not have a shared behavioral profile among selectively bred rat lines. However, a subgroup of high drinking individuals in an outbred cohort showed behavioral similarities to one of the selectively bred lines. Alcohol exposure showed small, but sex-dependent, effects on behavior and endogenous opioid peptide levels. Together, these studies provide new information about adolescent behavior and associations to early-life stress and alcohol in males and females, relationships not extensively studied in adolescence.

Altered corticosterone levels and social play behavior after prolonged maternal separation in adolescent male but not female Wistar rats
- 2017
-
In: Hormones and Behavior. - : Elsevier BV. - 0018-506X .- 1095-6867. ; 87, s. 137-144
-
Journal article (peer-reviewed)abstract
- Early-life socio-environmental factors are crucial for normal developmental processes; adverse experiences early in life can therefore lead to detrimental effects in several physiological systems. The aim of this study was to examine short-term effects of early adverse experiences in a maternal separation (MS) rodent model. In this study two separation conditions were used: daily 15-(MS15) or 360-min (MS360) separation of the litter from the dam during postnatal day 1-21. In early adolescence, male and female offspring were subjected to a single-isolation procedure with analysis of corticosterone levels prior to and after isolation. In addition, social play behavior was assessed during mid-adolescence. There was a clear difference between male and female offspring in both tests performed. There was no difference in corticosterone levels between the female MS groups, whereas MS360 males showed higher baseline and recovery corticosterone levels than MS15 males. The amount of pinning, a specific social play behavior, was affected by rearing with MS360 males having a higher frequency than MS15 males, while there was no difference between the female MS groups. The observation that males but not females are affected by MS360 has previously been reported for adult animals, and herein we show that this difference is present already in adolescence. Changes in corticosterone levels and social behavior following early-life adversity have been associated with adult behavioral alterations, and our results confirm that these changes emerge already within adolescence.

Behavioral profiling in early adolescence and early adulthood of male Wistar rats after short and prolonged maternal separation
- 2020
-
In: Frontiers in Behavioral Neuroscience. - : Frontiers Media SA. - 1662-5153. ; 14
-
Journal article (peer-reviewed)abstract
- Early-life stress and its possible correlations to genes, environment, and later health outcomes can only be studied retrospectively in humans. Animal models enable the exploration of such connections with prospective, well-controlled study designs. However, with the recent awareness of replicability issues in preclinical research, the reproducibility of results from animal models has been highlighted. The present study aims to reproduce the behavioral effects of maternal separation (MS) previously observed in the multivariate concentric square fieldTM (MCSF) test. A second objective was to replicate the adolescent behavioral profiles previously described in the MCSF test. Male rats, subjected to short or prolonged MS or standard rearing, were subjected to behavioral testing in early adolescence and early adulthood. As seen in previous studies, the behavioral effects of MS in the MCSF were small at both tested time points. When tested in early adolescence, the animals exhibited a similar behavioral profile as previously seen, and the finding of adolescent behavioral types was also reproduced. The distribution of animals into the behavioral types was different than in the initial study, but in a manner consistent with developmental theories, as the current cohort was younger than the previous. Notably, the Shelter seeker behavioral type persisted through development, while the Explorer type did not. The lack of basal behavioral effect after MS is in line with the literature on this MS paradigm; the working hypothesis is that the prolonged MS gives rise to a phenotype predisposed to negative health outcomes but which is not apparent without additional provocation.

Examining Female Resilience to Early Environmental Influences : Short- and long-term consequences on behaviour, HPA axis activity and alcohol intake after prolonged maternal separation
- 2017
-
Licentiate thesis (other academic/artistic)abstract
- Early-life experiences are an important factor influencing further development of the individual. Adverse experiences early in life, such as various kinds of abuse or neglect, are types of early-life stress that can adversely affect an individuals health, as well as contribute to the development of an array of disorders later in life. Most prominent is the increased risk for psychiatric disorders, primarily depression, anxiety-related and substance use disorders. Many of the implicated disorders also exhibit sex-dependent differences in prevalence and severity. Thus, it is important to consider sex-dependent effects when modeling early-life stress and its consequences. A common animal model for early-life stress is prolonged maternal separation (MS). MS is an umbrella term for different manipulations of the early environment of rodent pups. In this thesis, a prolonged MS condition with separation of rat litters from their dams for six hours per day during the first three weeks of life (MS360) was used. In male offspring MS360 have been associated with early-life stress and negative effects apparent during both adolescence and adulthood. The literature regarding female offspring is not as substantial as for the males, but it seems that females’ exhibit less pronounced or no effect after prolonged MS independent of separation time. In addition, the studies that have examined female offspring have done so in adulthood and thus, short-term consequences of prolonged MS possibly present during adolescence have not been investigated. The aim of this thesis is to provide a broad investigation into the consequences of prolonged MS in female offspring, in both adolescence and adulthood. As stated above, MS360 was used as the adverse rearing condition in this thesis. As control, daily short MS (15 min; MS15) was used; this ensured that all animals were handled equally, except for the length of separation. Any detected differences are thus due to the length of separation only. Three categories of assessments were used to evaluate short- and long-term consequences: 1) hypothalamus-pituitary-adrenal (HPA) axis assessments, 2) behavioral assessments and 3) assessment of voluntary alcohol consumption. HPA axis reactivity was assessed in adolescent and adult offspring by blood sampling before and after challenge. HPA activity was also evaluated after long-term alcohol consumption by measurement of the fecal corticosterone content. Behavior was assessed in adolescence by registration of social play behavior and in adulthood by generation of behavioral profiles in the multivariate concentric square fieldTM (MCSF). Alcohol consumption was evaluated using the modified intermittent alcohol access schedule with the two- (20% alcohol) and three- bottle (5% and 20% alcohol) free-choice paradigms. Female offspring did not differ depending on rearing condition in HPA reactivity in adolescence or adulthood. However, after the long-term alcohol intake, MS360 females had increased levels of corticosterone in their feces compared to MS15 females. No difference was detected in adolescent social play among female offspring and only a minor alteration was detected in the adult behavioral profile, where MS360 females had increased risk assessment compared to MS15 females. No effect of rearing condition was seen during the two-bottle choice paradigm of alcohol intake, while whole- group differences over time were discovered. Alcohol intake and preference were highest the first week of access and directly after a two-week deprivation period, apart from those time-points, intake and preference were maintained on a stable level. In the three-bottle choice, an interaction with rearing condition was revealed for the total alcohol preference, however this only translated to a minor group-dependent difference. In conclusion, females reared under a prolonged MS paradigm exhibited no or only minor basal changes in HPA axis reactivity, behavior and alcohol consumption. However, after long-term alcohol intake females subjected to prolonged MS had increased corticosterone excretion into feces. That differences only emerge after long-term perturbation can be a sign that females have higher buffering capabilities than males after early-life adversity, as modeled through prolonged MS, and thus require additional challenges before consequences become apparent. This thesis highlights the importance of considering sex when studying the impact of early-life stress, and that the choice of animal model needs to be considered carefully in relation to the research question posed.

Few long-term consequences after prolonged maternal separation in female Wistar rats
- 2017

In: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 12:12
-
Journal article (peer-reviewed)abstract
- Environmental factors during the early-life period are known to have long-term consequences for the adult phenotype. An intimate interplay between genes and environment shape the individual and may affect vulnerability for psychopathology in a sex-dependent manner. A rodent maternal separation model was here used to study the long-term effects of different early-life rearing conditions on adult behavior, HPA axis activity and long-term voluntary alcohol intake. Litters were subjected to 15 (MS15) or 360 min (MS360) of daily maternal separation during postnatal day 1–21. In adulthood, the behavioral profiles were investigated using the multivariate concentric square field™ (MCSF) test or examined for HPA axis reactivity by cat-odor exposure with subsequent characterization of voluntary alcohol intake and associated changes in HPA axis activity. Adult female offspring showed mostly no, or only minor, effects of MS360 on behavior, HPA axis reactivity and long-term alcohol intake. Instead, more pronounced effects were found dependent on changes in the female’s natural hormonal cycle or by the choice of animal supplier. However, changes were revealed in corticosterone load after long-term alcohol access, as females subjected to MS360 had higher concentrations of fecal corticosterone. The present findings are in line with and expand on previous studies on the long-term effects of maternal separation and the sex-dependent effects, with regard to behavior and voluntary alcohol intake. Why female rats show increased resilience compared to males using the present experimental protocol for maternal separation remains to be further investigated.

Revive! Reactions to migration between different embodiments when playing with robotic pets.
- 2012. - 8
-
Conference paper (peer-reviewed)abstract
- This paper explores the issues that arise in the context of the migration of a robotic pet between different embodiments and the associated design challenges. In the following, we describe the perceptions that a group of children have of a dinosaur character crossing the boundary between its robotic embodiment (the Pleo commercial pet), and its virtual counterpart on a mobile phone. We analyse the children's perceptions of, as well as emotional reactions to, the migration of this character, and show how seemingly subtle variations in the migration process can affect the children's perception on the character and its embodiments. Among other findings, gaps in the migration process, or perceived unresponsiveness, appeared to be accompanied by anxiety in the participating children. Based on our results, we point to yet unsolved design challenges for migration in interactions with embodied characters, and offer insights for migration implementation.

Conference paper (peer-reviewed)abstract
- More and more technologies are emerging that aim to support sports activities, for example there are jogging apps, cycling computers and quadcopters for sportspeople to videorecord their actions. These new technologies appear to become more and more popular, yet interaction design knowledge how to support the associated exertion experiences is still limited. In order to bring practitioners and academics interested in sports-HCI together and examine the topic "in the wild", we propose to go outside and jog around the CHI venue while using and discussing some of these new technologies. The goal is to investigate and shape the future of the field of sports-HCI.

Conference paper (peer-reviewed)abstract
- There has been a significant increase of interactive technologies to support sports activities. Examples are heart rate monitors for cyclists, jogging apps on mobile phones and GPS sports watches for extreme sports. Despite consumer popularity, there is little knowledge about how they should be designed in order to support the exertion activity. Based on CHI’13’s success of conducting a special interest group outdoors, we propose jogging with technology to discuss sports support interactive systems and investigate what future opportunities and challenges exist.

Challenges for SMEs Entering the IoT World – Success is about so Much More than Technology
- 2017
-
In: ProceedingIoT '17 Proceedings of the Seventh International Conference on the Internet of ThingsArticle No. 16 Linz, Austria — October 22 - 25, 2017. - New York, NY, USA : ACM Press. - 9781450353182
-
Conference paper (peer-reviewed)abstract
- We describe a case in which a small company with no competence in the Internet of Things has attempted to develop a connected product. Many of the issues that have come up around this process are not centered around the technology or the technical solution. Instead, the IoT brings additional challenges connected to the change of the customer-provider relationship, the need for a new business model, the need to understand the IoT ecosystem to make a product fit in, and the challenge of getting access to all the different competences needed. Our results suggest that governmental strategies, funding systems, investors and other stakeholders need to broaden the perspective on the IoT from a technological focus to include many other aspects that must be in place for companies to succeed in the IoT world, such as business models and customer relationship, as well as the positioning of a product in an IoT ecosystem.

Changing my life one step at a time : Using the twelve step program as design inspiration for long term lifestyle change
- 2012
-
In: NordiCHI 2012. - New York, NY, USA : ACM. - 9781450314824 ; , s. 711-720
-
Conference paper (peer-reviewed)abstract
- To explore how people manage and maintain life style change, we conducted interviews with eight members of different Twelve Step Fellowships with 2-23 years of recovery about how they maintain and develop their recovery in everyday life. They reported how identification, sharing, and routines are keys to recovery. Our lessons for design concerns how these concepts support recovery in a long term perspective: Sharing to contribute in a broader sense to the fellowship and to serve as an example for fellow members created motivation even after 20 years of recovery; reflecting over routines in recovery was essential since life is constantly changing and routines need to fit into everyday life; concrete gestures were helpful for some of the abstract parts of the recovery work, such as letting go of troubling issues. Design aimed to support maintenance of lifestyle change needs to open up for ways of sharing that allow users to contribute their experiences in ways that create motivation, and support users in reflecting over their routines rather than prompting them on what to do.

Community-Based Innovation among Elite Orienteers
- 2017
-
In: Proceedings of the 8th International Conference on Communities and Technologies. - New York, NY, USA : Association for Computing Machinery (ACM). - 9781450348546 ; , s. 87-95
-
Conference paper (peer-reviewed)abstract
- We have studied a form of community innovation within the sport of orienteering, which in the Nordic countries consist of a closely knit group with a strong sense of community. This study shows how the processes for developing new technologies are driven by a strong sense of idealism, with little or no commercial motivation. Thus, this represents a kind of community development and sharing with a number of unique characteristics. While the community is central to participants' endeavours of developing their systems, the participants are not representative of the typical member. On the contrary, they are examples of a minority that put in significant efforts of contributing to the larger group. What we argue is unique about the case we have presented is that the technology development starts out from a few number of highly motivated individuals that through limited collaboration with others builds technologies that get extensive proliferation and use within the community.

Couch mobility – the cell phone’s most important feature at home is mobility
- 2012. - 9
-
Conference paper (peer-reviewed)abstract
- A preliminary analysis of diary study of cell phone use in the home shows that mobility is an important feature at home and phones are more mobile than laptop computers with wifi. The phone adds functionality to the home, such as text messaging, reminders and integrated picture taking and sending. The needs of mobile phone use in the home are similar to the needs in traditional mobile use situations: mobility, quick access, ease of use.

Design and Implementation of Multi-Device Services
- 2007
-
Doctoral thesis (other academic/artistic)abstract
- We present a method for developing multi-device services which allows for the creation of services that are adapted to a wide range of devices. Users have a wide selection of electronic services at their disposal such as shopping, banking, gaming, and messaging. They interact with these services using the computing devices they prefer or have access to, which can vary between situations. In some cases, the services that they want to use func-tions with the device they have access to, and sometimes it does not. Thus, in order for users to experience their full benefits, electronic services will need to become more flexible. They will need to be multi-device services, i.e. be accessible from different devices. We show that multi-device services are often used in different ways on different devices due to variations in device capabilities, purpose of use, context of use, and usability. This suggests that multi-device services not only need to be accessible from more than one device, they also need to be able to present functionality and user interfaces that suit various devices and situations of use. The key problem addressed in this work is that there are too many device-service combinations for developing a service version for each device. In-stead, there is a need for new methods for developing multi-device services which allows the creation of services that are adapted to various devices and situations. The challenge of designing and implementing multi-device services has been addressed in two ways in the present work: through the study of real-life use of multi-device services and through the creation of a development method for multi-device services. Studying use of multi-device services has gener-ated knowledge about how to design such services which give users the best worth. The work with development methods has resulted in a design model building on the separation of form and content, thus making it possible to create different presentations to the same content. In concrete terms, the work has resulted in design guidelines for multi-device services and a system prototype based on the principles of separation between form and content, and presentation control.

Drifting off course : how sports technology can use real-time data to add new dimensions to sports
- 2016
-
In: Proceedings of the 15th International Conference on Mobile and Ubiquitous Multimedia. - New York, NY, USA : Association for Computing Machinery (ACM). - 9781450348607 ; , s. 1-4
-
Conference paper (peer-reviewed)abstract
- We have built Drift, an application that measures and provides feedback on how far from the ideal path an orienteer has deviated, to study how sports apps can draw on real-time data to enrich sports activities. Orienteering is an outdoor navigation sport requiring mental skills and fast running through the terrain. Participants appropriated deviation into their practice and found a variety of ways it could integrate with common orienteering practice. Interaction around deviation provided possibilities for new forms of sporting practice and social interactions. Deviation as a measure allowed this because it was highly specific and well-grounded in a specific skill of the sport. We believe this use of data in real time has the possibility of supporting and renewing sports activity as well as offering new opportunities for design.

Gathering design requirements for a microcommunity - the case of preschool parents and teachers
- 2009. - 1
-
Reports (other academic/artistic)abstract
- A microcommunity for preschool is a community for parents, teachers and other people involved in a preschool child group. The community is a tool for distributing and exchanging information and complements the traditional face to face communication and paper notes in that it makes information available from other places than the home and the preschool facilities. We present a first design iteration for preschool microcommunities with parents and teachers. Teachers have worked with a prototype tool to create microcommunities that has been made available to parents. We present a set of design principles for preschool microcommunities and a new design of the tool.

Generating speech user interfaces from interaction acts
- 2005. - 1
-
Reports (other academic/artistic)abstract
- We have applied interaction acts, an abstract user-service interaction specification, to speech user interfaces to investigate how well it lends itself to a new type of user interface. We used interaction acts to generate VoiceXML-based speech user interface, and identified two main issues connected to the differences between graphical user interfaces and speech user interfaces. The first issue concerns the structure of the user interface. Generating speech user interfaces and GUIs from the same underlying structure easily results in a too hierarchical and difficult to use speech user interface. The second issue is user input. Interpreting spoken user input is fundamentally different from user input in GUIs. We have shown that it is possible to generate speech user interfaces based on. A small user study supports the results.

Journal article (peer-reviewed)abstract
- Sports are an important part of many people’s lives. They are rewarding and motivating, but people appreciate them for a variety of reasons: Sports are personal and social, are fun but have health benefits, and can also be both enjoyable and painful. While motivation, fun, and sociality are elements often used as starting points in interaction design, we argue that for many athletes, these elements are already present and do not need to be specifically designed for. In this special section we have selected work that complements such an approach by focusing on novel viewpoints on interaction design in sports.

Interaction Acts for Device Independent Gaming
- 2002. - 1
-
Reports (other academic/artistic)abstract
- Porting computer games to new platforms can be a cumbersome work, since many parts of a game is platform specific. This is due to the fact that game developers try to maximise user's experience when playing a computer game, and to make the most of every device the game runs on. We use game and device independent interaction acts to describe user-game interaction for networked games that are accessed from many different devices. A device independent description of the game interactivity allows for remote access from different (semi)-generic interaction engines, as well as device optimisation for the same game application.

”It’s just easier with the phone” – a diary study of Internet access from cell phones
- 2009. - 1
-
In: Pervasive Computing. - Berlin : Encyclopedia of Global Archaeology/Springer Verlag. - 9783642015151 ; , s. 354-371
-
Conference paper (peer-reviewed)abstract
- We conducted a diary study of how 19 experienced users access Internet from cell phones. Our findings show that participants often chose the cell phone to access the Internet even though they had access to a computer, and the most common location for Internet access from the phone was the home. Reasons for choosing the phone over the computer were speed, convenience and a desire to use the phone. The phone is kept close and is always on which makes it convenient to use. The traditional motivation for mobile services ”finding out something about where you are” only accounts for 15% of the material.

Maintaining life change and supporting maintenance with design – what can we learn from Twelve Step recovery?
- 2011. - 10
-
Reports (other academic/artistic)abstract
- The project has created a design for a mobile service for personal Twelve Step work and situated Twelve Step work within the space of internet therapy and mobile services. The Twelve Step program helps addicts to recover from addiction and obsessive behavior, and their families to recover from the effects of living with an addict. Since recovery touches upon all aspects of life, mobile technology is a useful tool. The design presented below consists of three functions: · compiling the daily rhythm – helping users reflect over their routines through data collection and visualization, · rolling the dice - helping users break out of negative thinking by suggesting activities, · a gesture for letting go – helping users let go of issues they cannot handle. They are grounded in interviews and literature and will be further tested in future projects. Here, they are described and their minimal technical requirements are listed.

Mobile access to real-time information-the case of autonomous stock brokering
- 2004
-
In: Personal and Ubiquitous Computing. - : Springer Science and Business Media LLC. - 1617-4909 .- 1617-4917. ; 8:1, s. 42-46
-
Journal article (peer-reviewed)abstract
- When services providing real-time information are accessible from mobile devices, functionality is often restricted and no adaptation of the user interface to the mobile device is attempted. Mobile access to real-time information requires designs for multi-device access and automated facilities for the adaptation of user interfaces. We present TapBroker, a push update service that provides mobile and stationary access to information on autonomous agents trading stocks. TapBroker is developed for the Ubiquitous Interactor system and is accessible from Java Swing user interfaces and Web user interfaces on desktop computers, and from a Java Awt user interface on mobile phones. New user interfaces can easily be added without changes in the service logic.

On the design of television as a service based on average TV watching
- 2010. - 6
-
Reports (other academic/artistic)abstract
- Ten households were interviewed about their TV watching to inform the design of TV services. Our participants were average TV viewers who had Internet access but were not technically advanced or frequent users of the Internet as a source for TV material. We found that the flow of programs that broadcast television brings to viewers was the most important motivation for our participants to turn to the TV on-demand possibilities they had access to. Examples of triggers were social cues from people talking about things seen on TV, or time-shifting issues such as missing all or part of programs in the broadcast flow. Special interests such as sports were also a strong motivation for on-demand behavior. For the viewers, linear and on-demand TV watching was intertwined. We conclude that on-demand services should be integrated with broadcast TV in the design of future TV services.

Online behavior from desktop and mobile devices are connected
- 2010. - 8
-
Conference paper (peer-reviewed)abstract
- Cell phones and other mobile devices are used to access the Internet even at home and at work where computers are easily available. They are no longer a mere backup to the computer. This means that it makes little sense to study Internet access from mobile devices separate from other Internet access. We need new methods that encompass online behavior from desktop computers and mobile devices as well as stationary and mobile online behavior.

-
In: Peripheral Interaction: Embedding HCI in EverydayLife<em></em>. - : INTERACT. - 9780620574112 ; , s. 27-32
-
Conference paper (peer-reviewed)abstract
- We believe that sports is a domain that would both provide valuable input to the area of peripheral interaction, as well as benefit from peripheral interaction itself. We present two pilot studies on peripheral interaction for crosscountry skiing and golf using vibration feedback and audio feedback respectively. We believe the results of these initial studies are encouraging and aim to pursue the concept of peripheral interaction for the sports domain.
