Abstract

A sports board (e.g., a snowboard, ski, or surfboard) has a sensor panel comprising a plurality of individual sensors on a surface thereof such that deflection or vibration of surface of the sports board due to contact with a surface of the medium being ridden (e.g. snow or water) causes the individual sensors of the sensor panel to detect such contact. Each sensor on the sensor panel may be a simple switch, piezoelectric sensor, strain gauge, or a variable resistance type sensor. The sensors are monitored so as to detect the points of contact of the lower surface of the sports board with the snow or water. Detailed information related to the contact between the sports board and the snow or water is processed so as to provide auditory, visual or training information.
