- Several research studies have shown the importance of physical exercise. The global gym and fitness industry faced a transition from traditional gyms to virtual fitness training during the pandemic lockdowns. A proliferation of applications is available to provide different digital gym experiences. Advagym is one example that uses sensors to track and give feedback to gym goers. Sony's R&D Center Lund Laboratory has developed a Camera-based Tracking System (CTS) which aims to offer an automatic free weight exercise tracking solution with Advagym. The main goal of this paper is to align the Advagym application combined with CTS for free weight exercise (FWE) tracking and to conduct a comparative study of four different user interfaces presenting FWE tracking to increase the user experience. The main contribution of this paper is to elucidate knowledge about which UI feedback of FWE given for the “gym-goer” was preferred.

- With the emerging technology called the Internet of Things (IoT), we can now connect computing devices and sensors to the Internet. The IoT sensors serve to collect data, pushing it and sharing it with a whole network of connected devices. We decided to explore how to utilize IoT data to increase the user experience from a commercial gym application called Advagym. Advagym is a commercial solution already available in the market, which aims to digitize the gym experience, where a retrofit solution is used to fit IoT devices on gym machines to track performance data from users’ workouts. The main goal of this paper is to utilize IoT data from Advagym’s IoT sensors for velocity-based training (VBT) and conduct a comparative study of three different user interfaces presenting VBT data to increase the user experience. The main contribution of this paper is an analysis of user preferences regarding the user interface of VBT feedback during a gym workout.

A Mental Health and Well-Being Chatbot : User Event Log Analysis
- 2023
-
Ingår i: JMIR mhealth and uhealth. - : JMIR Publications. - 2291-5222. ; 11

Tidskriftsartikel (refereegranskat)abstract
- Background: Conversational user interfaces, or chatbots, are becoming more popular in the realm of digital health and well-being. While many studies focus on measuring the cause or effect of a digital intervention on people’s health and well-being (outcomes), there is a need to understand how users really engage and use a digital intervention in the real world.Objective: In this study, we examine the user logs of a mental well-being chatbot called ChatPal, which is based on the concept of positive psychology. The aim of this research is to analyze the log data from the chatbot to provide insight into usage patterns, the different types of users using clustering, and associations between the usage of the app’s features.Methods: Log data from ChatPal was analyzed to explore usage. A number of user characteristics including user tenure, unique days, mood logs recorded, conversations accessed, and total number of interactions were used with k-means clustering to identify user archetypes. Association rule mining was used to explore links between conversations.Results: ChatPal log data revealed 579 individuals older than 18 years used the app with most users being female (n=387, 67%). User interactions peaked around breakfast, lunchtime, and early evening. Clustering revealed 3 groups including “abandoning users” (n=473), “sporadic users” (n=93), and “frequent transient users” (n=13). Each cluster had distinct usage characteristics, and the features were significantly different (P<.001) across each group. While all conversations within the chatbot were accessed at least once by users, the “treat yourself like a friend” conversation was the most popular, which was accessed by 29% (n=168) of users. However, only 11.7% (n=68) of users repeated this exercise more than once. Analysis of transitions between conversations revealed strong links between “treat yourself like a friend,” “soothing touch,” and “thoughts diary” among others. Association rule mining confirmed these 3 conversations as having the strongest linkages and suggested other associations between the co-use of chatbot features.Conclusions: This study has provided insight into the types of people using the ChatPal chatbot, patterns of use, and associations between the usage of the app’s features, which can be used to further develop the app by considering the features most accessed by users.

Konferensbidrag (refereegranskat)abstract
- Mental health chatbots are particularly useful for those who are isolated and may have difficulty attending services or for those who are reluctant to speak to a professional. In this study, the usability and trust of a chatbot known as ’ChatPal’ has been assessed. ChatPal has been developed by an interdisciplinary team encompassing health service providers, local authorities, charities and universities to promote positive mental wellbeing among individuals in rural areas across Europe. This study employed a usability test protocol to recruit representative users to complete a set of tasks using the ChatPal chatbot. Usability issues were assessed along with trust and users’ satisfaction on the System Usability Scale and the Chatbot Usability Questionnaire. The study shows the usability issues and trust with a mental health chatbot and highlights recommendations for improvement.

HomeRuleML : a model for the exchange of decision support rules within smart environments
- 2007
-
Ingår i: IEEE International Conference on Automation Science and Engineering, 2007. - Piscataway, NJ : IEEE Communications Society. - 1424411548 - 9781424411542 ; , s. 513-520

Konferensbidrag (refereegranskat)abstract
- The demands for smart environments, which can help to facilitate as well as monitor independent living are increasing. With this comes a desire for decision support rules to process data recorded from such environments. However, testing and evaluating rules can be both time-consuming and indeed stressful for the inhabitants. Within this paper we propose a model, referred to as HomeRuleML, for representing decision support rules for smart environments. The motivating factor behind such a proposal is to provide a widely and freely accessible set of rules which can be openly used and exchanged within the research domain and beyond. This model has the potential to decrease the time required for deployment, and inevitability improve the inhabitants' quality of life. In the paper we explain in detail the structure of adopting this approach and also provide an indication of the typical types of software tools required for its use.

COGKNOW Development and evaluation of an ICT-device for people with mild dementia
- 2007
-
Ingår i: Medical and Care Compunetics 4. ; , s. 166-177
-
Konferensbidrag (refereegranskat)abstract
- Dementia is a progressive, chronic disease affecting 5% of all persons above 65 and over 40% of people over 90. The aim of the COGKNOW project is to achieve a breakthrough with research that addresses the needs of those with dementia, particularly those with mild dementia living in the community. This entails cognitive reinforcement in four main areas: helping people to remember, helping to maintain social contact, helping with performing daily life and recreational activities and finally enhance feelings of safety. Based on a sound foundation of needs reported in dementia literature, workshops and individual interviews have been carried out with dementia sufferers and their carers in three European countries. A ranked analysis of information from workshops and interviews, and the state of the art of successful ICT solutions will be the basis for formulating the functionalities of the technical solution and for the development of a cognitive prosthetic device with associated services for people with mild dementia. The research and evaluation will be conducted from human factors, technology, and business perspectives in three phases of one year each. In this paper we discuss the design of the COGKNOW project, the first results of the user needs inquiry workshops and the ICT solutions the COGKNOW project will focus on in the first year.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To develop a successful user-validated cognitive prosthetic device with associated services to help persons with mild dementia.Setting: The ICT solution will be developed by a consortium of eleven institutes in eight countries in Europe. It will be tested and evaluated by users (persons with dementia and their carers) in 3 European cities - Amsterdam, Belfast and Luleå.Methods: To identify and analyse the needs of persons with dementia, workshops and interviews were conducted with Alzheimer patients suffering from mild dementia, and their carers in three European cities. A literature search was also performed to identify existing proven effective ICT solutions for persons with dementia.Results: The most important needs and the most preferred ICT solutions identified by participants were (i) Activity reminders e.g. for eating meals; (ii) Item locators; (iii) Picture dialling to keep in contact with family and friends; (iv) Support for pleasure activities; (v) Enhancement of feelings of safety. Conclusion: Based on the needs identified, a prototype solution will be built, tested and modified as an iterative process. The device will ultimately be evaluated to see if it can enhance feelings of autonomy and quality of life of persons with dementia.

Ingår i: ECCE 10. - New York : ACM Digital Library. - 9781605589466 ; , s. 11-18
-
Konferensbidrag (refereegranskat)abstract
- Motivation - Develop a portable, mobile information and communication device with specific applications that meet the identified needs of people with mild dementia. Research approach - A qualitative study with a user centred design was applied: Three iterative development cycles of one year each were performed, in which around 15 persons with mild dementia and their carers participated in each cycle of development to attune the functions and form of the cognitive prosthetic to their needs and wishes. A mixed methods approach of qualitative interviews and standardised tools were used for the evaluations that were performed by formulating research questions and assigning appropriate methods for data collection before, during and after the field tests at the end of each development cycle. Findings/Design - The COGKNOW Day Navigator consists of a touch screen, a mobile device, sensors, a home hub and a central server. Several features such as colours and icons, can be adjusted to personal preferences, which was much appreciated by users. The functions to support people in their daily activities were overall appreciated, though there were individual differences in preferences and abilities to use them. Research limitations/Implications - It was recommended to perform an impact study within the target group for a longer period of time when the system is considered stable and to make use of a randomised controlled design in a larger study population. Originality/Value - The research built upon previous evidence of needs of people with mild dementia and the findings are valuable in directing further research and innovation. However, it was found that this technology can be complex to implement in a manner that ensures good quality of service delivery during field tests. Take away message - The work has shown the value of designing an analysis framework for development of assistive technology that gives a strong voice to people with dementia and their carers.

Ingår i: eChallenges 2010 Conference. - Piscataway, N.J : IEEE Communications Society. - 9781424483907
-
Konferensbidrag (refereegranskat)abstract
- This position paper describes the evolution of economic and other support for companies in Europe, before defining and describing innovation. The section on innovation describes how innovation has evolved and describes how network-centric, cyclical models of innovation are becoming more ubiquitous. The use of models such as triple-helix explicitly recognises the value of partnerships and the different stakeholders and their roles in facilitating and supporting innovation. But such models do not explicitly recognise the value of users and user-driven innovation. The paper explains the role of living labs as innovation facilitators involving users, describes the difficulties in the business community understanding the value of the living lab concept, and outlines how innovation models can utilise living labs and their users for economic benefit

- As demographic ageing impacts across the world, health and welfare organisations are seeking new paradigms of care that address people's needs as well as being inherently more scalable than the incumbent processes and services. The aim of this paper is to describe the current situation in Europe with information on service provision, before signposting some possible new ways to develop sustainable business models that support care models. The paper uses a case study approach to examine the issues in the introduction of such business models, from a perspective of the translation of research proof of concepts into business services and from the perspective of developing innovations from research that address unmet or poorly considered needs of user. The paper shows how several innovative European projects are anticipating the need for service change and are designing their research outcomes to match the needs of service commissioners more fully. The conclusion discusses several different approaches before drawing together strands of the work and providing tentative recommendations on the way forward to develop new inclusive technology-enhanced services in health and social care.

- Those suffering from mild dementia exhibit impairments of memory, thought and reasoning. It has been recognised that the deployment of technological solutions to address such impairments may have a major positive impact on quality of life. In the current paper we present results from the CogKnow Project following the evaluation of a suite of mobile and home based cognitive prosthetics to assist persons suffering from mild dementia. The results following an evaluation of the technology conducted with 16 people with mild dementia (and their carers) across 3 different trial sites are outlined. The paper concludes with details describing the process by which the outcomes of the evaluation will be used to guide the developments of a second generation of both mobile and home based cognitive prosthetic.

- Those suffering from mild dementia exhibit impairments of memory, thought and reasoning. It has been recognised that deployment of technological solutions to address such impairments may have a major positive impact on the quality of life and can be used to help perform daily life activities hence maintaining a level of independence. In this paper we present an overview of our current investigations into how technology can be used to improve the quality of life of the ageing person with mild dementia. Specifically, we detail the methodology adopted for our work, outline results attained from a series of workshops to identify user needs and finally present how these user needs have been mapped onto the design of home based assistive technologies.

- This work describes a potential solution to the problems caused by the heterogeneous nature of the data which may be collected within smart home environments. Such information may be generated at an intra- or interinstitutional level following laboratory testing or based on in-situ evaluations. We offer a solution to this problem in the form of a system/application/format independent means of storing such data. This approach will inevitably support the exchange of data within the research community and form the basis of the establishment of an openly accessible data repository. Within this abstract we present the outline design of homeML, an XML based schema for representation of information within smart homes and through exemplars demonstrate the potential of such an approach. An example of the typical type of software browser required for the data representation is also presented.

A Multilingual Digital Mental Health and Well-Being Chatbot (ChatPal): Pre-Post Multicenter Intervention Study
- 2023
-
Ingår i: Journal of Medical Internet Research. - : JMIR Publications. - 1438-8871. ; 25
-
Tidskriftsartikel (refereegranskat)abstract
- Background: In recent years, advances in technology have led to an influx of mental health apps, in particular the development of mental health and well-being chatbots, which have already shown promise in terms of their efficacy, availability, and accessibility. The ChatPal chatbot was developed to promote positive mental well-being among citizens living in rural areas. ChatPal is a multilingual chatbot, available in English, Scottish Gaelic, Swedish, and Finnish, containing psychoeducational content and exercises such as mindfulness and breathing, mood logging, gratitude, and thought diaries.Objective: The primary objective of this study is to evaluate a multilingual mental health and well-being chatbot (ChatPal) to establish if it has an effect on mental well-being. Secondary objectives include investigating the characteristics of individuals that showed improvements in well-being along with those with worsening well-being and applying thematic analysis to user feedback.Methods: A pre-post intervention study was conducted where participants were recruited to use the intervention (ChatPal) for a 12-week period. Recruitment took place across 5 regions: Northern Ireland, Scotland, the Republic of Ireland, Sweden, and Finland. Outcome measures included the Short Warwick-Edinburgh Mental Well-Being Scale, the World Health Organization-Five Well-Being Index, and the Satisfaction with Life Scale, which were evaluated at baseline, midpoint, and end point. Written feedback was collected from participants and subjected to qualitative analysis to identify themes.Results: A total of 348 people were recruited to the study (n=254, 73% female; n=94, 27% male) aged between 18 and 73 (mean 30) years. The well-being scores of participants improved from baseline to midpoint and from baseline to end point; however, improvement in scores was not statistically significant on the Short Warwick-Edinburgh Mental Well-Being Scale (P=.42), the World Health Organization-Five Well-Being Index (P=.52), or the Satisfaction With Life Scale (P=.81). Individuals that had improved well-being scores (n=16) interacted more with the chatbot and were significantly younger compared to those whose well-being declined over the study (P=.03). Three themes were identified from user feedback, including “positive experiences,” “mixed or neutral experiences,” and “negative experiences.” Positive experiences included enjoying exercises provided by the chatbot, while most of the mixed, neutral, or negative experiences mentioned liking the chatbot overall, but there were some barriers, such as technical or performance errors, that needed to be overcome.Conclusions: Marginal improvements in mental well-being were seen in those who used ChatPal, albeit nonsignificant. We propose that the chatbot could be used along with other service offerings to complement different digital or face-to-face services, although further research should be carried out to confirm the effectiveness of this approach. Nonetheless, this paper highlights the need for blended service offerings in mental health care.

Ingår i: 2021 IEEE Symposium on Computers and Communications (ISCC). - : IEEE. ; , s. 1-6
-
Konferensbidrag (refereegranskat)abstract
- This study reports on the development and ‘in the wild’ trialling of a chatbot (ChatPal) which promotes good mental wellbeing. A stakeholder-centered approach for design was adopted where end users, mental health professionals and service users were involved in the design which was centered around positive psychology. In the wild usage of the chatbot was investigated from Jul-20-Mar-21. Exploratory analyses of usage metrics were carried out using the event log data. User tenure, unique usage days, total chatbot interactions and average daily interactions were used in K-means clustering to identify user archetypes. The chatbot was used by a variety of age groups (18-65+) and genders, mainly those living in Ireland. K-means clustering identified three clusters: sporadic users (n=4), frequent transient users (n=38) and abandoning users (n=169) each with distinct usage characteristics. This study highlights the importance of event log data analysis for making improvements to the mental health chatbot.

Can Chatbots Help Support a Person’s Mental Health? Perceptions and Views from Mental Healthcare Professionals and Experts
- 2021

Ingår i: ACM Transactions on Computing for Healthcare. - : ACM Digital Library. - 2691-1957 .- 2637-8051. ; 2:3
-
Tidskriftsartikel (refereegranskat)abstract
- The objective of this study was to understand the attitudes of professionals who work in mental health regarding the use of conversational user interfaces, or chatbots, to support people’s mental health and wellbeing. This study involves an online survey to measure the awareness and attitudes of mental healthcare professionals and experts. The findings from this survey show that more than half of the participants in the survey agreed that there are benefits associated with mental healthcare chatbots (65%, p < 0.01). The perceived importance of chatbots was also relatively high (74%, p < 0.01), with more than three-quarters (79%, p < 0.01) of respondents agreeing that mental healthcare chatbots could help their clients better manage their own health, yet chatbots are overwhelmingly perceived as not adequately understanding or displaying human emotion (86%, p < 0.01). Even though the level of personal experience with chatbots among professionals and experts in mental health has been quite low, this study shows that where they have been used, the experience has been mostly satisfactory. This study has found that as years of experience increased, there was a corresponding increase in the belief that healthcare chatbots could help clients better manage their own mental health.
