A driver-free and fast-response input device based on a smart tablet

Abstract

The invention discloses a driver-free fast response input device based on an intelligent tablet, and a method for connecting an Android tablet computer to a computer system as a ps2 universal keyboard, so as to solve the problem of slow response in the existing scheme of using an intelligent tablet system as an input device , and during the first use, plug and play cannot be achieved, and large smart devices often do not have the problem of wireless network access. The invention includes a graphic interface, a human-computer interaction API, and an I / O mapping middleware. By adding a simple hardware circuit, supplemented by corresponding software, the android embedded device can be connected to the computer as a PS2 keyboard, thus meeting the requirements of large smart devices for input devices such as flexible input means, friendly interaction mode, fast response, Relevant requirements that are universal.

Description

technical field [0001] The invention relates to a technology for connecting a smart tablet to a computer as an external input device. The computer terminal does not need any driver and software support. Under any operating system, the computer terminal regards the device as an actual physical universal input device. In particular, it relates to a technology for connecting an Android embedded device to a computer system as a ps2 universal keyboard. Background technique [0002] At present, large-scale digital intelligent equipment is widely used in the production and life of today's society, such as large-scale medical detection and treatment equipment, digital machine tools, assembly line robotic arms, etc. Due to the long time required for most of its development and the aging of its input and output equipment, most of them still use old-fashioned mechanical keyboard. In the process of updating these large smart devices, due to the complexity of their own control, flexible...
