Systems and methods for actively resisting touch-induced motion

Abstract

A system for actively resisting touch-induced motion includes a touchscreen device and a processing circuit. The touchscreen device includes one or more sensors configured to generate motion data based on a motion of a touchscreen display of the touchscreen device, where the motion is induced by a touch on the display. The touchscreen device further includes one or more motion control devices configured to apply a force to the display. The processing circuit is configured to determine, based on the motion data, a force to counteract the motion. The processing circuit is further configured to cause the motion control devices to apply a force to the display to counteract the motion of the display.
