Wearable sensor system with gesture recognition for measuring physical performance
First Claim
1. A system for quantifying physical performance and for using gesture recognition to control system operation comprising:
- means for measuring three axes of linear motion, said measuring means being secured to a user'"'"'s finger;
means for inputting said measured three axes of linear motion into processing means;
means for starting said measuring of said three axes of linear motion via hand positioning and/or hand movement;
means for minimizing spurious measurements of said three axes of linear motion;
means for providing an acceleration magnitude corresponding to said measured three axes of linear motion;
means for stopping said measuring of said three axes of linear motion via hand positioning and/or hand movement; and
means for calculating and indicating predetermined parameters of physical exercise, whereby said measuring means provide parameters pertaining to acceleration magnitude and high-frequency, low amplitude finger movements and/or gestures, said acceleration magnitude and said finger movements providing continuous information from a finger start gesture to a finger stop gesture to said processing means for quantifying and displaying physical performance data for a time period determined by said finger start gesture and said finger stop gesture.

Abstract
A wearable sensor system with gesture recognition for measuring physical performance 98 includes a sensor ring 100 for providing signals corresponding to finger movement to an information processor 101. The sensor ring 100 internally includes an accelerometer 106 for measuring motion of a predetermined finger, the measured motion corresponding to an exercise routine performed by a user of the system 98, a processor 109 for conditioning the signals from the accelerometer 106, and a transceiver 108 for transmitting the conditioned signals to the information processor 101 for display and feedback to the user for accessing the quality of the exercise. The system 98 further includes means for allowing the user to start and stop the processing of the measured finger motion by moving the finger with sensor ring 100 thereon a predetermined distance and speed.
