A hand-controlled hardware device for interacting with a computer terminal or entering data from a digitizer. A mouse is used to make selections and position the cursor to fields in computer forms when interacting with graphical user interfaces. A digitizer mouse is used to trace features and enter x,y coordinates of features.

A hand-held computer input device that generates signals that increment, i.e., slew, the position of a cursor on a video display. Note: A mouse is placed on a flat surface and moved manually in the direction in which it is desired to move the cursor. A mouse has momentary switches ("buttons") that may be finger-operated to trigger an event after the cursor is positioned correctly.
