Motivating Physical Exercise in the Elderly with Mixed Reality Experiences

The rapid aging of developed societies is creating an increasing number of cases of dementia and other aging-related diseases. Physical exercise has been shown to be beneficial for retaining cognitive, as well as physical function. In this paper we describe a system that we have developed for motivating older people to exercise. We begin by demonstrating how activity declines with age using an analysis of survey data (from 2003–2015) reported by the U.S. Bureau of Labor and Statistics on American Time Use Usage. We use multiple discriminant analysis to characterize which activities tend to become more, or less frequent as people age. We then review previous exergame approaches for motivating physical activity. After this we discuss a pedaling system that is designed to motivate and facilitate physical activity in the elderly using a combination of competition, social interaction, and engaging video content. We conclude with a discussion of how to adapt exergaming innovations to the context of use.
