Handwriting pad using image identifying technology for computer input

Abstract

To overcome the defects that the prior handwriting pad needs complex electronic circuit technology, a great amount of electronic elements need to be arranged in a handwriting pen, the handwriting pen is heavy to hold by a user, the button on the handwriting pen needs to be pressed continuously in the writing process, and the like, the invention provides a handwriting pad using image identifying technology for computer input, which comprises a transparent panel, a panel base, a microcamera, an assistant light source, a handwriting pen head and a handwriting pen rod. The handwriting pad using image identifying technology for computer input is characterized in that the transparent panel is made of transparent material, one end of the transparent panel is fixed on the panel base, the microcamera is fixed on the panel base and arranged at the bottom of the transparent panel, the microcamera can photograph the movement of the handwriting pen head on the surface of the transparent panel and can be connected with a computer by a data wire, the handwriting pen head and the handwriting pen rod are fixed together, the assistant light source is fixed on the panel base, the light emitted by the assistant light source can cover the surface of the whole transparent panel and be irradiated to the handwriting pen head moving on the surface of the transparent panel, and the identifying performance of the microcamera on the handwriting pen head can be improved.

Description

Technical field: [0001] The invention relates to the field of computer peripheral equipment, in particular to a handwriting tablet which utilizes image recognition technology for computer entry. Its main function is to input the handwriting trajectory image into the computer, and then use the corresponding image processing software to convert it into the corresponding X, Y coordinates, and reflect the trajectory drawn by the user on the handwriting board on the computer screen. Background technique: [0002] At present, the handwriting board is one of the very important input devices used for information entry. It occupies a very important position in our life today. The current handwriting board technology is very mature. From the technical principle, it can be divided into electromagnetic type, touch type, Ultrasonic positioning type, photoelectric type, etc. These are all through electronic technology to convert the trajectory of the stylus into digital quantities—X, Y co...
