Abstract

A control handle extends at least partially around a hub. Multiple arms extend in respective different directions between the hub and the control handle. Sensors sense an effect of an input force applied to the control device and acting on each of the arms relative to multiple directions. A controller interface is coupled to the sensors, to enable communication with a controller of the video equipment. Such a control device could be implemented in conjunction with a video equipment pedestal that also includes a base and an equipment support. The control device could be used to drive motion of the video equipment pedestal based on readings by the sensors. A user input device could be provided to control one or more of virtual mass, virtual friction, enabling and disabling of driving motion, and/or enabling and disabling of motion relative to any one or more of multiple axes.
