Three case studies on methods of working with older people in the design of new technologies

The proportion of older adults in the population is rapidly increasing and the proportion of younger adults to care for them is decreasing. Part of the solution to support older adults in living independently is to provide them with appropriate assistive technologies. To develop technologies that are effective for older adults we need methodologies that are appropriate for working with this user group. Yet there is little systematic research on how to work with older adults and how to adapt methods already used with younger adults. This paper reports on three case studies which investigated the use focus groups, expert evaluations and user evaluations with older adults. In the case of focus groups, the size of the focus group was investigated; for expert evaluations, an existing set of heuristics for evaluating apps for older adults was investigated; for user evaluations, a low-fidelity prototype design was evaluated using think-aloud protocol

HSP: A Tool for Heat Stress Prevention for Farm Workers

We present the initial development of an integrated application for heat stress and heat related illness prevention in farm workers. In developing the application we have follow the OSHA guidelines and an extended project includes the social, cultural and economic factors of farm workers. Even though, our development focus is on workers in the California fields, we believe our project will be useful in multiple situations where individuals are exposed to extreme heat working conditions. This paper describes the motivation for our development, the overall approach we are following, and the first version of our application

Several studies suggest that an increase of nocturia is seen with the onset of age, occurring in around 70% of adults over the age of 70. Its appearance is associated with detrimental quality of life for those who present nocturia, since it leads to daytime sleepiness, cognitive dysfunction, among others. Currently, a voiding diary is necessary for nocturia assessment; these are prone to bias due to their inherent subjectivity. In this paper, we present the design of a low-cost device that automatically detects micturition events. The device obtained 73% in sensibility and 81% in specificity; these results show that systems such as the proposed one can be a valuable tool for the medical team when evaluating nocturia. © 2013 IEEE.https://ieeexplore.ieee.org/document/845445

How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRR’s Rehabilitation Engineering Research Centers

Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a “total approach to rehabilitation”, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970’s, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program

Using Technology to Address the Problems of Malnutrition and Dehydration in Older Adults

Malnutrition and dehydration of important problems for older adults even in developed countries such as the UK and both have many serious health consequences. This programme of research developed an app, MyHealthyLiving, to support older adults in monitoring their intake of liquids and fruit and vegetables. I followed a user-centred design lifecycle and conducted six studies, starting with focus groups to understand the older users’ needs and wishes, through expert and user evaluations, to a two week field study of the use of the app by 15 older people. Using the data from the user evaluations, a new set of evidence-based heuristics for the development and evaluation of tablet apps for older people was also produced
