TRAJECTORY DETECTION AND FEEDBACK SYSTEM FOR TENNIS
First Claim
1. A device for analyzing a trajectory of a tennis ball, the device comprising:
- one or more cameras for recording video frame data used to characterize a trajectory of a tennis ball generated by a player during a tennis related activity;
a logic device designed or configured to i) receive the video frame data, ii) identify the tennis ball in the video frame data, iii) generate trajectory parameters that characterize one or more states of the tennis ball along its trajectory and iv) generate feedback information using the trajectory parameters; and
at least one output mechanism for providing the feedback information.

Abstract
A system for capturing and analyzing a trajectory of a tennis ball or other object associated with a play of a game of tennis and providing feedback is described. The system may be designed to capture and analyze a trajectory of a tennis ball during various activities related to the play of a game of tennis. The system may be configured to provide immediate feedback that may be utilized by a player to improve their performance as well as provide entertainment value above and beyond what is normally associated with the play of a game of tennis. Further, the system may be operable for use in an area where tennis is normally played during normal playing activities, such as player playing a game or practicing on an outdoor tennis court. The system may be operable to account for factors associated with its ambient environment, such as wind, temperature and humidity.
