Journal article (peer-reviewed)abstract
- This paper presents a person-centred model and a tangible computing approach to better adapt television media to meet two important needs of older people: social inclusion in their immediate surroundings and better support for one’s own reflections. Method The research project was carried out as a part of the construction, planning and implementation of a new nursing home. The implemented infrastructure enabled television watching at three levels: the regular (broadcast programmes), the internal and the personal. The internal level consisted of an in-house broadcast television channel and two media centres placed in common areas. The personal level had individualised functions. The entire concept is referred to as ‘extended television’. This paper describes the early implementation phase of the internal television channel and the personal television photo album. It also examines the consequences of a person-centred model and a tangible computing approach. Participation in the use of the ‘extended television’ together with older people, relatives and care workers, semistructured dialogues with these people, and observations of the television usage were conducted. Furthermore, the care workers were invited to comment on the prototypes very early in the process. Results Both the internal channel and the personal television photo album were used by older residents and iteratively adapted. However, too many factors and routines varied to get statistically sound results. On the other hand, the research shows that the person-centred study design utilised provided positive results in a setting with constantly changing conditions. Discussion This design encourages further investigations regarding how new conceptual television design can enrich the everyday lives of older people. The results also indicate the plausibility of television photo albums providing new opportunities for reminiscence compared to traditional ones, and that the internal channel resulted in possibilities for social inclusion in the nursing home examined.

Journal article (peer-reviewed)abstract
- Objectives: The objectives were to study long-term material wear of tracheostomy tubes made of silicone (Si), polyvinyl chloride (PVC), and polyurethane (PU) after 3 and 6 months of clinical use. Study Design: The study has a prospective and comparative design. Methods: Nineteen patients with long-term tracheostomy, attending the National Respiratory Center in Sweden, were included, n = 6 with Si tubes, n = 8 with PVC tubes, and n = 5 with PU tubes. The tubes were exposed to the local environment, in the trachea for 3 and 6 months and analyzed by scanning electron microscopy, attenuated total reflectance Fourier transform infrared spectroscopy, and differential scanning calorimetry. Results: All tubes revealed severe surface changes. No significant differences were established after 3 or 6 months of exposure between the various materials. The changes had progressed significantly after this period, compared to previously reported changes after 30 days of exposure. The results from all analyzing techniques correlated well. Conclusions: All tubes, exposed in the trachea for 3-6 months, revealed major degradation and changes in the surface of the material. Polymeric tracheostomy tubes should be changed before the end of 3 months of clinical use.

Journal article (peer-reviewed)abstract
- OBJECTIVES: The objectives were to compare the duration of use of polymeric tracheostomy tubes, i.e., silicone (Si), polyvinyl chloride (PVC), and polyurethane (PU), and to determine whether surface changes in the materials could be observed after 30 days of patient use. METHODS: Data were collected from patient and technical records for all tracheostomized patients attending the National Respiratory Center in Sweden. In the surface study, 19 patients with long-term tracheostomy were included: six with Bivona TTS Si tubes, eight with Shiley PVC tubes, and five with Trachoe Twist PU tubes. All tubes were exposed in the trachea for 30 days before being analyzed by scanning electron microscopy (SEM) and attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR). New tubes and tubes exposed in phosphate-buffered saline were used as reference. RESULTS: Si tubes are used for longer periods of time than those made of PVC (P < .0001) and PU (P = .021). In general, all polymeric tubes were used longer than the recommended 30-day period. Eighteen of the 19 tubes exposed in patients demonstrated, in one or more areas of the tube, evident surface changes. The morphologic changes identified by SEM correlate well with the results obtained by ATR-FTIR. CONCLUSIONS: Si tracheostomy tubes are in general used longer than those made of PVC and PU. Most of the tubes exposed in the trachea for 30 days suffered evident surface changes, with degradation of the polymeric chains as a result.

GiraffPlus : A System for Monitoring Activities and Physiological Parameters and Promoting Social Interaction for Elderly
- 2014
-
In: Human-Computer Systems Interaction. - Cham : Springer. - 2194-5357. - 9783319084909 - 9783319084916 ; , s. 261-271
-
Book chapter (peer-reviewed)abstract
- This chapter presents a telehealth system called GiraffPlus supporting independent living of elderly in their own home. GiraffPlus system is a complex system which monitors activities and physiological parameters in the home using a network of sensors. The elaborated information is presented to the primary user, the elderly, and to secondary users like health care and home care providers and possibly to family members as a help to assess possible health and wellbeing deterioration, provide acute alarms, and support health procedure. The secondary users can also visit the elderly via the Giraff, a teleoperated robot that can communicate and move in the home under the control of the secondary user. The chapter focusses in particular on the deployment of the system in six real homes in Sweden, Italy and Spain. The chapter outlines the technological various components used, the expectations of the users and the evaluation method.

Dementia, Design and Technology : Time to get involved.
- 2009
-
Editorial collection (other academic/artistic)abstract
- The interest for the design of life environments for persons with dementia is growing stronger among architects, engineers, social scientists and those responsible for housing and health care planning. This development is connected to the enlarged group of people that become afflicted by this disease and to the fact that a safe environment is proved to be very important for their well-being as well as for their relatives and carers. Dementia is a progressive syndrome and the risk increases by age. Since there is no cure for this disease what we can do is to improve their life situation. It is often called the disease of the relatives because it deeply effects relations and daily life. It is also a disease that the individual has to live with. Most often the meaning of daily routines and the use of common technical applications and services changes dramatically. Efforts are made to design housing for persons with dementia and systems to support their carers. Technologies and a variety of aids is expected to help in developing efficiency of these services, supporting family carers and providing solutions for independent living and improved quality of life of persons with dementia. So far, persons with dementia have not been involved in most of the design processes. Their voice has been used by their informal or formal carers or dementia experts. As a consequence most solutions available are focusing mainly on safety and needs of the carers while other needs and possibilities are mainly neglected. Published result confirms that the lack of user involvement did not facilitate the use of common applications, nor assistive technologies. The aim of this book is to increase the understanding of subjective needs of people with dementia and the way this understanding can promote and improve their involvement in design processes. We will present examples of design and design interventions where people with dementia are involved and what is required from technology when the user has an illness causing dementia. Because of the fact that approaches to involve people with dementia in design as active users of technology are still quite novel, we will also discuss ethical issues and challenging experiences gathered in our studies. The authors represent on-going design and research in Scandinavia and United Kingdom.

Laggards as Innovators? : Old Users as Designers of New Services & Service Systems
- 2011
-
In: International Journal of Design. - 1991-3761 .- 1994-036X. ; 5:3, s. 89-98
-
Journal article (peer-reviewed)abstract
- Involving users in the design process is increasingly discussed as the quickest and most reliable way to capture the needs of users and consumers. In parallel, the fastest growing population segment in Asia and the West is older people. This article asks whether their involvement in the design process could accelerate a growing service market and if so, how? It addresses a knowledge gap that constrains service provision for a growing market of older people and which underestimates older people's potential contribution in the early phases of the development of new services. The current role of older users is limited to that of test persons later in the design process or as objects of randomized samples that explore consumers' reactions to existing products. The present case study provides an empirical example of how old users can be involved in the early stages of service design. In doing this, the article questions the concept of old users as laggards. It suggests great potential to include such users - been arounds - as sources of innovation in the earlier phases of the design process if they have the right tools and opportunities to act. In identifying unsatisfied needs and potential market solutions, the inclusion of old users in user-driven projects can contribute to the generation of business ideas.

Capturing seniors' requirements for assistive robots by the use of attention cards
- 2012
-
In: NordiCHI '12 Proceedings of the 7th Nordic Conference on Human-Computer Interaction. - New York : ACM Press. - 9781450314824 ; , s. 783-784
-
Conference paper (peer-reviewed)abstract
- This paper describes and reflects upon a senior-oriented participatory design methodology that facilitates communication, attention and creativity. Previous research indicates that seniors tend to lose focus and start cross talking during workshops, which results in broad and superficial findings. However, our workshop methodology indicates that the use of attention cards helps the seniors to stay focused by visualizing concrete first person narrative scenarios. This paper does not describe the findings of the workshop. Instead, we use our experience to propose ways in which the process of eliciting user requirements for novel technologies from old users with no prior experience of the technology in question can be made.

Elderly People's Perceptions of a Telehealthcare System : Relative Advantage, Compatibility, Complexity and Observability
- 2013
-
In: Journal of technology in human services. - : Informa UK Limited. - 1522-8835 .- 1522-8991. ; 31:3, s. 218-237
-
Journal article (peer-reviewed)abstract
- The use of telehealthcare systems to promote independent living for elderly people is growing. The results presented in this article, derived from an initial user lab test of a telecare system-GiraffPlus-indicate that the crucial factor for adoption of telehealthcare systems is not usability but the system's ability to support autonomy in everyday life. Eleven users tested the usability and reported what they perceived as possible benefits of having such a system at home. To support autonomy, customization is crucial for the system to be perceived as meaningful for the individual. Our analysis confirms previous research. © 2013 Copyright Taylor and Francis Group, LLC.
