Ultimate trainer: instructional feedback for ultimate frisbee players.

ABSTRACTUltimate frisbee is a rapidly growing sport that is played in more than 42 countries. Although it is often seen as a lighthearted pastime, significant training and practice are necessary to achieve an average level of throwing proficiency, and it is difficult for new players to map the flight of the frisbee to their throwing action. In this paper, we present Ultimate Trainer, a frisbee augmented with electronics that gives a player visual and haptic cues based on grip strength and angle of release, along with flight information such as rotation speed and time of flight. We give a brief account of our design and implementation with results of preliminary testing.
