Generation of user activity feedback

Abstract

A system for generating a user activity feedback comprises a sensor device ( 101 ) and a user device ( 103 ). The sensor device ( 101 ) comprises a force sensor ( 105, 107 ) which determines a measured force distribution resulting from a user activity, such as a sporting or exercise activity. A transmitter ( 109 ) transmits the measured force distribution to the user device ( 103 ) where a receiver ( 111 ) receives the measured force distribution. A context data processor ( 115 ) provides context data for the user, such as e.g. environment data or activity equipment data. A target processor ( 117 ) determines a target force distribution for the user activity in response to the context data and a feedback processor ( 113 ) generates the user activity feedback in response to the measured force distribution and the target force distribution. The user device can then present the user activity feedback to the user, e.g. as a real time audio signal suggesting performance corrections that can be made by the user.
