Abstract

Disclosed herein is a footplate assembly for monitoring foot position in real time, as a wheelchair is driven. Optionally, the footplate assembly can use an array of force-sensing resistors and infrared distance sensors to detect the pressure and location of the foot within the immediate confines of the footplate. The footplate assembly can be provided as an overlay to an existing wheelchair footplate structure, or the footplate assembly can be integrated into or replace an existing wheelchair footplate structure.
