Abstract
A touch control input method and a device is disclosed for controlling cursor movement on a computer screen or for controlling object movement of an apparatus such as a machine or a robot. A user-manipulable member having an exterior contact surface of known configuration is provided to sense the motion of a user through the physical contact with the contact surface. User contact on the contact surface is transmitted to a force sensing means disposed between the user-manipulable member and a support. The movement of the user contact on the contact surface are derived from the signals output from the force sensing means. The contact force may be used as a means to determine the object's motion and response sensitivity simultaneously, while providing kinesthetic and tactile feedback to the user.
