Fuente: Wipo "Sensorization" A system, method, and computer program product for analyzing force sensor data is provided. Force sensor data collected from a plurality of force sensors positioned underfoot is analyzed to detect foot contact events and/or a foot contact period. Foot contact and/or foot off can be detected based on inflection points identified in the force signal data received from the plurality of sensors. Identifying foot contact events by detecting inflection points in the force sensor data can increase the sensitivity of detecting both foot contact and foot off. The use of inflection points also allows both foot contact and foot off to be identified even when these foot contact events occur at different force signal heights. Methods for determining ground reaction force data and correcting the magnitude of ground reaction force signals are also provided.
