Abstract
A single control element device provides a user with absolute coordinate information and enables user control of a computer cursor and emulation of mouse clicks. The single control element is user-moved relative to a surface having a dynamic coefficient of friction that reduces false double-clicks. The device may be used by handicapped persons and emulates left mouse clicking and double clicking by recognizing downward force of the single control element into the surface, and recognizes upward movement of the single control element away from the surface as a right mouse click.
