Abstract

A wheelchair system includes a wheelchair including a plurality of force sensors including at least three force sensors. A rigid seat pan is placed in contact with each the plurality of force sensors at a different position on the rigid seat pan so that the rigid seat pan does not contact the frame and forces on the rigid seat pan are transferred to the plurality of force sensors. Each of the plurality of force sensors is in communicative connection with a processor system. A memory system is in communicative connection and an interface system is in connection with the processor system and a user interface system in communicative connection with the processor system. Instructions stored on the memory system are executable by the processor system to determine a value of a variable related to a distribution of force on the rigid seat pan over time.
