Abstract

A glanceable interface presented by a computing device to a user while the user engages in physical exercise can provide information regarding exercise-related data within the context of the user'"'"'s exercise-oriented goals. In particular, the glanceable interface can display the difference between a user'"'"'s current exercise level and a target level, optionally with instructions how to reach the target level. Once the target level is reached, the glanceable display can provide raw exercise-related data to the user. In addition, virtual competition can be based on a target-achievement-score that is based on the amount of time, and the accuracy with which, a competitor maintains their exercise level within a target exercise level zone. Competitors can be automatically selected based on the closeness of their target-achievement-scores to the user'"'"'s target-achievement-score, so long as at least one competitor has a higher target-achievement-score than the user so as to further motivate the user.
