Foot-operated controller, device and furniture comprising it, method of operating it

Abstract

The invention concerns a foot-operated controller, comprising a top platform () having a top surface for receiving the feet, a bottom cup () having a lower surface () of curved convex shape for rotating () on its lower surface (), wherein the top platform () is attached to the bottom cup (), rotation sensors () for measuring rotations of the top platform () about a first yaw axis (Z), a second roll axis (X) and a third pitch axis (Y). According to the invention, it comprises at least one strength sensor () for measuring strength applied on the top platform (), means () for generating control signals (CS) from the rotations and strength measured, means () to register an initial rotation position of the platform () relative to at least one the axes (Z, X, Y) when the strength sensor () measures a strength representative of the presence of the feet, wherein the initial rotation position corresponds to a rest position of the feet on the top platform () when the user is sitting and to the top platform () inclined by at least a not null angle to the rear about the third pitch axis (Y) relative to an horizontal position (P) of the platform (), wherein the control signals (CS) are generated to take as a reference (CSO) the initial rotation position.
