Televideo technology (e.g., Skype) has potential to support adults as they age by facilitating their interactions with people remotely; this potential may be even greater for adults aging with pre-existing mobility impairments, who face challenges interacting with others in person due to lack of transportation or accessibility. Our research employed questionnaire and interview methodologies to investigate this understudied population about their attitudes toward televideo technology for supporting social engagement, healthcare provider access, and physical activity. Participants were 14 adults aging with self-reported mobility impairments (50-70 years of age). Overall, participants were open to accepting televideo technology for social engagement, healthcare provider access, and physical activity. Participants perceived these technologies to be useful and perceived additional benefits, including the feeling of ''being there'' by enabling the viewing of facial expressions and the environment of the other person. Concerns included perceptions that televideo technologies lack security and privacy. Participants also expressed concerns that these technologies are difficult to use and are difficult to learn to use. The findings have implications for education, training, and deployment of televideo technology for homebased interventions for adults aging with pre-existing mobility impairments.

Exergames have been growing in popularity as a means to get physical exercise. Although these systems have many potential benefits both physically and cognitively, there may be barriers to their use by older adults due to a lack of design consideration for age-related changes in motor and perceptual capabilities. In this paper we evaluate the usability challenges of Kinect-based exergames for older adults. Older adults rated their interaction with the exergames system based on their perceived usefulness and ease-of-use of these systems. Although many of the participants felt that these systems could be potentially beneficial, particularly for exercise, there were several challenges experienced. We discuss the implications for design guidelines based on the usability challenges assessed.

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.
