Abstract: Implementations relate to hand presence sensing at a control input device. In some implementations, a control input device includes a base member, a handle coupled to the base member and configured to be manually contacted at a grip portion of the handle and moved by a hand of a user in one or more degrees of freedom, one or more control input sensors configured to detect positions or orientations of the handle in the one or more degrees of freedom, and a presence sensor coupled to the base member. The presence sensor has a sensing field, and at least a portion of the sensing field is located proximate to the handle.
