Display cursor control device with enhanced multiple dimensional tilt angle operation

摘要

A data-handling and processing system includes an image-display cursor-control device for controlling an image display cursor of an image display. The system is further operated a pad for placing and moving the image-display cursor-control device and the pad has a curved surface. The image-display cursor-control device further includes an accelerometer for sensing a tilt angle in moving along the curved surface of the pad. The image-display cursor-control device further includes a container housing for containing the accelerometer therein. The container housing has a curved bottom surface for conveniently tilting the display-cursor control device to change an elevation level of the accelerometer
