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.

Claims

a sensor device comprising;

a force sensor for determining a measured force distribution resulting from a user activity, and

means for transmitting the measured force distribution to a user device; and

the user device comprising;

means for receiving the measured force distribution,

context means for providing context data for the user,

target means for determining a target force distribution for the user activity in response to the context data, and

feedback means for generating the user activity feedback in response to the measured force distribution and the target force distribution.

2. The arrangement of claim 1 wherein the context data comprises user activity environment data.

3. The arrangement of claim 1 wherein the context data comprises user activity equipment data.

4. The arrangement of claim 1 wherein the context means is arranged to determine the context data as a context data set selected from a plurality of context data sets associated with different user activities.

5. The arrangement of claim 1 wherein the target means is arranged to select the target force distribution in response to a characteristic of the measured force distribution.

6. The arrangement of claim 1 wherein the user device further comprises means for storing a target force distribution determined in response to the measured force distribution.

7.
