    Older Adults’ Perceptions of Supporting Factors of Trust in a Robot Care Provider
    (Hindawi, 2018) Stuck, Rachel E. ; Rogers, Wendy A.
    The older adult population is increasing worldwide, leading to an increased need for care providers. An insufficient number of professional caregivers will lead to a demand for robot care providers to mitigate this need. Trust is an essential element for older adults and robot care providers to work effectively. Trust is context dependent.Therefore, we need to understand what older adults would need to trust robot care providers, in this specific home-care context. This mixed methods study explored what older adults, who currently receive assistance from caregivers, perceive as supporting trust in robot care providers within four common homecare tasks: bathing, transferring, medication assistance, and household tasks. Older adults reported three main dimensions that support trust: professional skills, personal traits, and communication. Each of these had subthemes including those identified in prior human-robot trust literature such as ability, reliability, and safety. In addition, new dimensions perceived to impact trust emerged such as the robot’s benevolence, the material of the robot, and the companionability of the robot. The results from this study demonstrate that the older adult-robot care provider context has unique dimensions related to trust that should be considered when designing robots for home-care tasks.

    Understanding 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.
