Pointing stick with tripod actuator for cursor control in a computer keyboard

摘要

Pointing stick assembly for use in a computer keyboard for cursor control is disclosed. The assembly includes a pointing button coupled through a plurality of rigid actuator legs to force sensors. For pointing operations, the pointing button is pressed in a desired direction by a user for moving a cursor in a corresponding direction on a display screen. Apertures are provided extending through one or more keycaps on the keyboard for mounting the pointing assembly. Each actuator leg is positioned in one of the apertures so that no additional keyboard space is required for the pointing device, thereby obviating a separate mouse, keyboard mounted trackball or the like.
