Abstract: A method in a video gaming system including a processor, a memory and a sensor system for capturing body motion is described. In one embodiment, the body motion can be associated with a person pretending to hit or launch an object, such as an object used in a sporting activity. In general, body motion can be associated with any activity involving similar body motions that are repeated during the activity. In a video game generated by the video gaming system, a consistency with which the repeated body motions are made over time can be used to determine an outcome for a single instance of the body motion. In a particular embodiment, a probability of a more desirable outcome resulting from the single instance of the body motion can increase as the consistency with which the repeated body motions are made increases.

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.

Abstract: A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and/or one or more observers in the area. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and/or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner.
