Using an invisible coach to help players achieve fitness goals in exergames while retaining immersion

Abstract

Two approaches to designing exergames exist: design a game with incidental exercise, or design an exercise program with an incidental game. We aim to combine the advantages of these approaches by developing an invisible coach that modifies gameplay in order to guide workouts while maintaining game immersion. This opens opportunities to guide players toward focused exercise goals, such as cycling at a desired intensity, or strengthening a weak muscle group, while allowing players to retain the sense of playing a game. We are investigating the design and efficacy of an invisible coach in the context of a novel strength training game.
