Technology, such as active videogames (AVG), have been used to promote leisure time physical activity because an estimated 46 million persons with a mobility limitation engage in play. However, most current AVG are not inclusive of those who experience difficulty standing, lower extremity weakness, poor motor control, or use an assistive device. Preliminary testing shows that adults with mobility limitations find a prototype touch pad videogame controller usable, and moderately enjoyable. However, the energy expenditure elicited by the touch pad videogame controller among adults with limited mobility is unclear. Additionally, user feedback identified several key areas of improvement to the prototype.

The purpose of this study is to 1) revise the low-fidelity prototype based on user feedback and usability testing, and 2) determine the exercise intensity elicited by the touch pad videogame controller among adults with a mobility limitation. Phase 1 will include a redesign of the current low-fidelity prototype based on feedback. In Phase 2, thirty adults with limited mobility will attend two lab visits and play videogames (1) with a standard hand-held controller, and (2) with the touch pad videogame controller. Outcome measures include energy expenditure, ratings of perceived exertion, enjoyment, and self-efficacy. After completion of this research, we plan to implement an 8-to-12-week intervention to test the efficacy of the touch pad videogame controller to improve the health-related fitness, adherence to habitual physical activity, and improve quality of life for those with limited mobility. Impact: This research may increase opportunities for exercise participation and promote healthier lifestyles among adults with a mobility limitation.
