POINTER CONTROL DEVICE

摘要

The present invention relates to the production of control commands (CmdP) that influence the position of a graphical pointer on a computer system display. A proposed pointer control device (100) comprises an essentially flat sensor surface (110) delimited by means of a boundary wall (115). An actuator object (130) having an essentially flat actuator surface is slided over a sensor means (120) in the sensor surface (110) to generate the control commands (CmdP). The actuator object (130) has such a configuration and such geometric proportions relative to a set of geometric proportions of the boundary wall (115) that when the actuator object (130) is placed on the sensor surface (110) with the actuator surface facing the sensor surface (110) and the actuator surface is positioned entirely within the boundary wall (115) the actuator object (130) is slidable over the sensor surface (110). Moreover, a portion of the actuator object (130) always covers the sensor means (120).
