Claim Text:
1. A method for detecting user hand movements and interpreting such movements as a computer input, comprising: positioning a wireless sensor device near a user's hand; positioning a first and a second wireless ranging device on the user's body a fixed distance apart such that the two wireless ranging devices form an axis relative to a portion of the user's body; conducting calibration operations that record distances and one or more calculated angles in memory while a user performs prescribed physical movements; determining a distance between the wireless sensor device and each wireless ranging device through wireless signal ranging techniques; calculating an angle between the wireless sensor device and the wireless ranging devices based on the determined distances; determining an estimated position of the wireless sensor device relative to the wireless ranging devices based on the determined distances and calculated angle; collecting a sequence of determined estimated positions of the wireless sensor device over a period of time; comparing the collected sequence of determined estimated positions of the wireless sensor device over a period of time to a database of gesture movement patterns to determine if there is a match within a predefined tolerance; correlating a computer input command to a recognized gesture; and executing the correlated computer input command in a computing device.
