ItemClosing the Capacity-Ability Gap: Using Technology to Support Aging With Disability(Gerontological Society of America, 2018) Mitzner, Tracy L. ; Sanford, Jon ; Rogers, Wendy A.There is a critical need to develop supports for older adults who have a wide range of abilities, including those aging with long-term impairments. Without appropriate support, many individuals will be functioning below optimal levels and will face participation barriers. Technology holds great promise to provide individualized support for a wide range of abilities and for a variety of domains. To ensure technology interventions are designed well and meet research-documented user requirements, we need more specific, actionable models to provide guidance for those developing and designing interventions. In this paper, we present the TechSAge Aging and Disability Model to bridge models from the aging and disability literatures and to disambiguate the population of individuals aging into disability from those aging with disability (i.e., pre-existing impairments). We also present the TechSAge Technology Intervention Model to support aging with pre-existing impairments, which provides direction and touch points for technology interventions. These models reflect the complex and dynamic interaction between age-related changes and an individual’s prior capabilities and limitations. We describe the need for these models with respect to filling a gap in the disability and aging literature by highlighting the importance of differentiating between age-related changes and long-term impairments when designing interventions. We also show the need for quantitative and qualitative data to refine the models given complexities of the current state of the literature and survey data. The TechSAge Technology Intervention Model can be used to drive and inform technology redesign and development.

ItemA Qualitative Approach to Understanding User Needs for Aging with Disability( 2018) Remillard, Elena T. ; Mitzner, Tracy L. ; Singleton, Jenny L. ; Rogers, Wendy A.There is a growing population of adults with long-term sensory and mobility impairments who are aging into older adulthood. Little is known about the everyday challenges and accessibility issues experienced by these individuals as they age and acquire age-related declines in addition to a pre-existing impairment. The present paper provides an overview of a large-scale interview study, currently in progress, exploring user needs of older adults with long-term vision, hearing, and mobility impairments. The structured interview is designed to elicit detailed information on task performance challenges across a wide range of daily activities, as well as strategies to manage those challenges. In this paper we provide case-study examples from each of the three impairment groups to convey the potential depth and breadth of insights about user needs among individuals aging with impairments that can be realized through this novel qualitative approach.

ItemUnderstanding older adults’ perceptions of and attitudes towards exergames(International Society for Gerontechnology, 2017) Barg-Walkow, Laura H. ; Harrington, Christina N. ; Mitzner, Tracy L. ; Hartley, Jordan Q. ; Rogers, Wendy A.Purpose Maintaining physical activity is a key component of successful aging and has benefits for both physical and cognitive functioning in the older adult population. One promising method for engaging in physical activity is through exergames, which are video games designed to promote exercise. Exergames have the potential to be used by a wide range of people, including older adults, in a variety of settings, such as at home, in community living environments, or senior centers. However, exergames have not been designed for older adults (e.g., with respect to their attitudes, needs). Thus, older adults may not adopt these systems if they perceive them as not useful or relevant to them. Method Twenty older adults (aged 60-79) interacted with two exergames, and were then interviewed about their perceptions of the system’s ease of use and usefulness, as well as their general attitudes towards the system. Results Participants identified the potential for exergames’ usefulness for various goals, such as to increase their physical activity. However, they also reported negative attitudes concerning the system, including perceiving barriers to system use. Overall, participants said they would use the system in the future and recommend it to other people at their age for improving health, despite these use challenges. Conclusion The older adults were open to adopting exergames, which could provide opportunities to increase physical activity. Given the participants’ overall positive perceptions of the usefulness of exergames, designers must address the perceived challenges of using these systems. Understanding barriers and facilitators for older adults’ use of exergames can guide design, training, and adoption of these systems.
