Exploring haptic feedback in exergames

Abstract

Exergames combine entertainment and exercise in an effort to encourage people to be more physically active. Although exergames require active input, interactions are less physical than those experienced in real-world exercise. Interactions can feel artificial, limiting the captivating experience exergames aim to provide. To address this problem, haptics have been proposed as a means of providing additional feedback to players through the sense of touch. However, there is very little empirical evidence supporting the benefits of haptics in exergames. To address this, we have identified and evaluated three ways in which haptic feedback can enhance exergames: by helping to balance group exercise among people of different fitness levels, by guiding players toward safe and healthy interaction, and by increasing peoples' sense of virtual presence in exergames. We present three novel exergames incorporating haptic feedback, and report on experiments investigating their success. We find that haptics which are consistent with actions displayed on-screen increase immersion and improve enjoyment. However, we discover pitfalls when using haptics to represent phenomena that do not have a physical basis. These results allow us to present a set of design issues for haptic feedback in exergames. © 2011 IFIP International Federation for Information Processing.
