By computer work the operator has to move the hand many times a day for placing the cursor correctly on the computer display by means of a pointer tool with consequent possible tensions in wrist, shoulder, neck etc, which can result in the commonly denoted "mouse injuries". For counteracting said "mouse injuries", a pointer tool for a computer appears in pad-shape and as a flattish body. A touch-sensitive plate is placed close to the front end of the flattish body for manipulating a cursor on a computer screen. A scroll function and at least two ergonomically suitably shaped pushbuttons are disposed in an ergonomically suitable way on the flattish body around the touch- sensitive plate. Simultaneous manual operation of all functions are enabled with minimal movements of the user's fingers. The pointer tool includes an ergonomic wrist support at the rear edge of the flattish body. |
