Abstract
A system and method to provide haptic and visual feedback of motion of the skier foot and the forces transmitted to the skiboot insole and consequently to the ski/snow interface. This system comprises a motion and force sensors and a haptic actuator embedded in the skiboot insole in communication with a smart-phone based analysis application, configured to calculate insole motion and orientation and the distribution of pressure points inside the skiboot, then to provide haptic feedback to the skier foot instructing on timing and direction of change in the pressure points necessary to achieve optimal turn parameters. Furthermore, analyzed together with GPS coordinates are transmitted by the application to the cloud based server for further processing. Graphical and numerical representation of data is superimposed over a 3D map of a slope which may be viewed on the user smart-phone or on a remote computer terminal.
