here's an excerpt of the patent:
A wireless communications device includes a motion-detecting device, such as a pedometer, that generates a signal upon detecting the user's motion. Quantified characteristics of the user motion are stored in memory of the wireless communications device. The quantified characteristics represent a predetermined objective that the user desires to achieve by performing the motion. A processor receives the signal from the motion-detecting device and uses the signal to monitor selected characteristics of the user's motion. The processor compares the selected characteristics and, when the comparison indicates that the user has achieved the predetermined objective, downloads reward data to the wireless communications device.
Further, you could have two people competing to help each other lose weight, that could compare users' exercise scores. The person who clocked the most steps then "steals" a reward from the loser’s device.
