People with Learning Disabilities and Smartphones: Testing the Usability of a Touch-Screen Interface

Mobile phone technology is becoming ubiquitous. However, a number of unique usability challenges are still unresolved, including small screen size, device orientation changes, and an array of interaction methods (tap, flick, pinch, etc.) These challenges may be particularly acute for people with learning disabilities. This study examined the usability of touchscreen interactions, the difficulties, and possible solutions. An app was developed in which (12) participants accessed Google Maps and manipulated it to find various London Underground station locations. Text input (a password), tap, swipe, and pinch were required, and their usage was analysed. Many participants were successful in finding the required information. However, many difficulties arose, including misunderstandings of the labelling (a live ‘Welcome’ button was not tapped, whereas a short list of instructions was erroneously seen as a menu and so erroneously tapped to access each step in the process) and an over-sensitive zoom feature. Three categories of error were formulated from the findings: affordance, user, and functionality. Recommendations are offered, such as using more appropriate ‘signage’ for link buttons (affordance); manipulating the zoom feature using + and - buttons rather than a ‘pinch’, which requires two fingered dexterity (functionality); and more formal training and familiarity (user)

The use of think-aloud and instant data analysis in evaluation research: Exemplar and lessons learned

AbstractWhile health information technologies have become increasingly popular, many have not been formally tested to ascertain their usability. Traditional rigorous methods take significant amounts of time and manpower to evaluate the usability of a system. In this paper, we evaluate the use of instant data analysis (IDA) as developed by Kjeldskov et al. to perform usability testing on a tool designed for older adults and caregivers. The IDA method is attractive because it takes significantly less time and manpower than the traditional usability testing methods. In this paper we demonstrate how IDA was used to evaluate usability of a multifunctional wellness tool, discuss study results and lessons learned while using this method. We also present findings from an extension of the method which allows the grouping of similar usability problems in an efficient manner. We found that the IDA method is a quick, relatively easy approach to identifying and ranking usability issues among health information technologies

A study plan for investigating Smart brush for better oral hygiene in frail elderly

Oral health in Australia’s older population is of great concern and studies show that two-thirds of residents in aged care facilities have significant oral problems. Cognitive, and functional alterations that accumulate while ageing leads to increasing care dependency which then impacts on the ability to maintain good oral health. This paper presents ideas for a pilot investigation into the effectiveness of smart brush technology for improving oral health among the elderly. The proposed pilot study will follow a design that incorporates a Critical Realist methodological perspective known as the Context- Initiative-Mechanism-Outcome approach with a theoretical perspective, the theory of interactive Media effects (TIME). This paper presents a proposition suggesting smart brush as a means for improving oral health among the elderly through identification of context (frail elderly), initiative (smart brush), mechanism (interaction with the smart brush affordances), and outcome (improved oral health). Both qualitative (interviews) and quantitative data (plaque score, brushing duration/coverage) will be collected and analyzed for testing the proposition

The effect of dyadic interactions on learning rotate gesture for technology-naïve older adults

Older adults having limited experience with modern computing technology may find it difficult to learn touch gestures, especially the more complex rotate gesture. Social interactions, as implied by social constructivism, are assumed to be powerful in enabling older adults to acquire the skill of touch gestures. The social effect can be reinforced with the motivational effect of digital games. To verify the assumption, we conducted empirical studies with 59 older adults, who were divided into two groups: 17 Singles and 21 Dyads. They were asked to play a set of digital games on a multi-touch tabletop. Results show that on average Dyads have spent significantly longer time in the games and have performed a significantly higher number of correct rotate gestures than Singles. Future work focuses on analyzing the emotional aspect of social interactions and identifying further applications of social gaming to other ageing issue

Obesity is a chronic condition that influences the quality of life of patients and families while increasing the economic burden for the world population. Multidisciplinary prevention programs are crucial to address it, allowing an early introduction of healthy behaviors into daily habits. Mobile health interventions provide adequate support for these programs, especially considering the gamification techniques used to promote users’ engagement. TeenPower is a multidisciplinary mHealth intervention program conducted in Portugal during 2018 to empower adolescents, promoting healthy behaviors while preventing obesity. An agile software development process was applied to the development of the digital platform that holds a web-based application and a mobile application. We also propose a model for future developments based on the user-centered design approach adopted for this development and the assessment conducted in each phase. The user-centered design approach model proposed has three distinct phases: (1) design study; (2) pre-production usability tests; and (3) post-production data. Phase 1 allowed us to obtain the high-fidelity version of the graphical user interfaces (n = 5). Phase 2 showed a task completion success rate of 100% (n = 5). Phase 3 was derived from statistical analysis of the usage of the platform by real end users (n = 90). We achieved an average retention rate of 35% (31 out of 90 participants). Each technique has provided input for the continuous design and improvement of the platform. This allowed the creation of a tailored platform that could meet users’ expectations. Nevertheless, the retention rate decreased significantly over a short period of time, revealing the need for further work in the improvement of the gamification experience.info:eu-repo/semantics/publishedVersio

Ageing Futures: Towards Cognitively Inclusive Digital Media Products

This thesis is situated in a moment when the theory and practice of inclusive design appears to be significantly implicated in the social and economic response to demographic changes in Western Europe by addressing the need to reconnect older people with technology. In light of claims that cognitive ageing results in an increasing disconnection from novel digital media in old age, inclusive design is apparently trapped in a discourse in which digital media products and interfaces are designed as a response to a deterministic decline in abilities. The thesis proceeds from this context to ask what intellectual moves are required within the discourses of inclusive design so that its community of theorists and practitioners can both comprehend and afford the enaction of cognitive experience in old age? Whilst influential design scholarship actively disregards reductionist cognitive explanations of human and technological relationships, it appears that inclusive design still requires an explanation of temporal changes to human cognition in later life. Whilst there is a burgeoning area of design related research dealing with this issue—an area this thesis defines as ‘cognitively inclusive design’—the underlying assumptions and claims supporting this body of research suggests its theorists and practitioners are struggling to move beyond conceptualising older people as passive consumers suffering a deterioration in key cognitive abilities. The thesis argues that, by revisiting the cognitive sciences for alternative explanations for the basis of human cognition, it is possible to relieve this problem by opening up new spaces for designers to critically reflect upon the manner in which older people interact with digital media. In taking a position that design is required to support human cognitive enactment, the thesis develops a new approach to conceptualising temporal changes in human cognition, defined as ‘senescent cognition’. From this new critical lens, the thesis provides an alternative ‘senescentechnic’ explanation of cognitive disconnections between older people and digital media that eschews reductionism and moves beyond a deterministic process of deterioration. In reassessing what ageing cognition means, new strategies for the future of inclusive design are proposed that emphasise the role of creating space for older people to actively explore, reflect upon and enact their own cognitive couplings with technology.Arts and Humanities Research Counci

MISMATCH BETWEEN OLDER ADULTS’ EXPECTATION AND SMARTPHONE USER INTERFACE

Smartphones have become ubiquitous communication tools for everybody, including older adults to stay connected with their family and access to information. However, mobile operators and developers mainly target the youngster cohort in mobile industry. With the rising ageing population, smartphone user interface and some mobile apps are not designed to cater the needs of older adults. This could hinder them from fully utilizing the smartphone functions and its services. A mobile-user interaction study using mixed-methods (questionnaire, interview and observation) was conducted to examine usability and user interface design issues of smartphone and mobile apps among 80 older adults in Malaysia. Four tasks design were ‘making voice calls’, ‘using phonebook’, ‘installing a mobile app from Google Play Store’, and ‘using WhatsApp’. The results were analysed both quantitatively (for usability evaluation) and qualitatively (for interviews and observation). The usability result revealed that the ‘voice call’ task had the highest success task completion rate (83.44%), followed by ‘phonebook’ (70.16%), ‘mobile app download’ (63.13%) and ‘using WhatsApp’ (60.42%). Three themes were emerged from the qualitative thematic analysis, which showed a mismatch between older adults’ expectation and smartphone user interface. A majority had never downloaded a mobile app before, and they had problems downloading it from Play Store. They perceived the Play Store feature as a place for children playing games. To close the discrepancy between user expectation and mobile design, the mobile designers and developers are required to consider the older adults’ needs for better usability of smartphone user interface design

THERAPEUTIC STRATEGY IN GAMIFICATION AND GAME BASED LEARNING FOR ELDERLY PEOPLE IN THAILAND

Purpose: This study aims to review the literature of the therapeutic strategies in gamification and a game-based learning for elderly people. During the increasing of the aging city in Thailand, how to prepare and how to live up the society are challenged. Gamification as a Game-based learning is a key issue in terms of conception. The conception of the game focuses on establishing trust with players and finding the right way to motivate the players to care for their health and to encourage the players to set goals. Methodology:A survey of healthcare for aging people was conducted in regard to technology-driven gamification.Gamified training appears to be highly engaging and does boost participant motivation.The survey attempts to examine Thai culture in terms of game technology and family networks and supports the influence the health-promoting behaviors among older persons. Main Findings:The reviews illustrate the role of game-based learning in therapeutic strategies. In accordance with the Gamification Concept, the concepts of games are broad in scope,encompassing various contexts, such as training. The results of this findings may influence Thai elderly to care their healthy by using gamification. The game design shows the Health Care Training Game and Gamification prototype. Implications:Gamification strategies may contribute to sustainable healthcare in Thailand.The designing game examines the therapeutic strategy game by establishing a technology-driven trust relationship with players, and then determining the best way to motivate the players to care for their health. Originality:Knowledge and skills can be improved by using game-based learning. A learning game is a self-contained unit with start, game play and ending activities. The games are based on a combination of well-known game-design principles and principles of task-oriented training and involve the manipulation of everyday physical objects
