MEDIA, SYSTEMS, AND METHODS FOR GAME-BASED EXERCISE TRACKING WITH VIRTUAL WORLD VARIATIONS

A compute device can receive a signal associated with a quantity of real-world activity (e.g., exercise) performed by a user. The compute device can define a quantity of virtual activity based, at least in part, on the quantity of real-world activity. The quantity of virtual activity can be different from the quantity of real-world activity. The compute device can send an indication of progress in a virtual world to an output device, for example, such that the user's progress is displayed.
