红外手指输入装置是使用本单位研制的红外发光管和PIN光电二极管而自行设计的,它的实验成功将为电子计算机提供一种新的人工干预输入装置。红外手指输入装置和触线装置、键盘一样,是对计算机进行人工干预的一种装置。它和表格显示器配用,作为人工存取数据的一种方式。在这里,它起到了键盘不能起的作用,又较之有触点的触线装置提高了可靠性。该装置在国外已用于空中交通管制系统中。
The infrared finger input device is designed by our own infrared LED and PIN photodiode. Its successful experiment will provide a new manual intervention input device for electronic computer. Infrared finger input device and the touch-line device, like the keyboard, is a device for human intervention in the computer. It is used with a form display as a way to access data manually. Here, it plays the role of the keyboard can not play, but also compared with the contact line device to improve the reliability. The device has been used abroad in air traffic control systems.
