Matching System for Correlating Accelerometer Data to Known Movements

Abstract

The present invention extends to methods, systems, and computer program products for providing a matching system for correlating accelerometer data to known movements. Data representing known movements can be obtained and stored in a database such as by processing and storing accelerometer data obtained from one or more accelerometers worn by a user while performing a particular movement. The accelerometer data obtained from a particular movement can be processed to generate a feature set descriptive of the accelerations associated with a particular movement or series of movements.

What is claimed: 
     
         1 . One or more computer storage media storing computer executable instructions which when executed by one or more processors on a portable computing device perform a method for identifying a particular movement from accelerometer data by comparing an identified sequence in the accelerometer data to known sequences, the method comprising:
 storing a plurality of entries in a database on a portable computing device, each entry representing one or more known sequences of accelerometer data that are generated when a particular movement is performed;   receiving accelerometer data from one or more accelerometers worn by a user while performing a first movement;   accessing the database to determine that the accelerometer data received from the one or more accelerometers includes the one or more known sequences of a first entry; and   determining that the first entry is associated with a first particular movement.   
     
     
         2 . The computer storage media of claim  18 , wherein the portable computing device is a smart phone. 
     
     
         3 . The computer storage media of claim  18 , further comprising:
 creating a new entry in the database, the new entry containing sequences of accelerometer data received from one or more accelerometers while the user is performing a custom movement.
