Hand input positioning device

Abstract

The invention provides a hand input positioning device, belonging to the technical field of pattern recognition. The device integrates wire and wireless modes, and sends the hand input data information to a computer by a data bus and wireless radio frequency respectively, thereby realizing the recognition of the hand input data information easily. The invention has the advantages of good practicability and operability, simple structure, short activation time, low power consumption, small resource usage, lower cost, longer wireless transmission range and better multipoint network connection ability.

Description

technical field [0001] The invention relates to the field of pattern recognition, in particular to a handwriting input device. Background technique [0002] A handwriting input device is a computer input device, such as a handwriting tablet, a digital tablet, etc., generally uses a special pen to write characters or draw graphics in a specific area. The handwriting input device records the trajectory of the pen through various methods, and then recognizes it as text or graphics. It can be used for circuit design, CAD design, graphic design, free drawing, text and data input, etc. After years of development, handwriting input technology has become more and more mature. At present, the mainstream handwriting input device products on the market include: wired tablet (there is a connection line between the tablet and the stylus), wireless tablet (the connection between the tablet and the stylus) No connecting wire) and wireless passive tablet (no connecting wire between the ta...

Problems solved by technology

[0006] Second, due to the complex structure of the Bluetooth protocol stack, it consumes a lot of system resources (occupying system resources is about 250Kb), and the Bluetooth device consumes a lot of power, and the development cost is relatively high;

[0007] Third, the transmission distance of Bluetooth is relatively short (only about 10 meters), and it is necessary to increase the transmission power to realize long-distance handwriting input. However, wireless handwriting tablets are generally powered by batteries, and a relatively large battery is required to achieve long distances. energy, and range is still limited by battery power;
