Hand Activated Input Device with Horizontal Control Surface

摘要

A cursor control device horizontally positioned operating surface is mounted on a vertical shaft connected to a biaxial joint which is enclosed in the base of the device. The hand of the operator rests on the operating surface and tips it in any direction so the shaft follows the movement of his/her hand. The motion is interpreted as X and Y coordinates on a computer display screen. The coordinate information is digitized and sent to the main computer to display a cursor on the display screen.
