A drawing tablet capable of measuring the position information of the drawing tablet

Abstract

A coordinate input device and method able to obtain position information are disclosed. The coordinate input device is provided with a master controller, a position information sensor is set in the coordinate input device, the position information sensor is connected with the master controller, and converts the position signal of the position information sensor to the digital signal, sends it to the master controller, and the master controller removes jitter from the digital signal sent by the position information sensor, sends it to the computer for processing, and obtains the position information of the coordinate input device. By the position information sensor obtaining its position information, converting it to the digital signal and sending it to the master controller, the master controller removing jitter, etc., from the digital signal and sending it to the computer, the computer performing the further process, the rotating change occurred by the page content displayed by the computer consistent with the coordinate input device can be realized.

Description

technical field [0001] The invention relates to the field of computer peripheral input devices, in particular to a drawing board capable of measuring position information of the drawing board. Background technique [0002] The working principle of the drawing board and drawing pen as the peripheral input device of the computer is: according to the movement of the drawing pen on the drawing board, determine the moving track of the drawing pen on the drawing board, the pressure on the drawing board and the inclination angle of the drawing pen etc., and transmit this information to the computer to achieve the purpose of painting. [0003] Generally, on the drawing board, a plurality of transverse coils are distributed horizontally, and the transverse coils are used for intermittently sending electromagnetic signals; meanwhile, a plurality of longitudinal coils are distributed longitudinally, and the longitudinal coils are used for receiving electromagnetic signals sent by the t...

Problems solved by technology

However, as far as the drawing board itself is concerned, another kind of position information may be generated during its use. For example, during the drawing process, the operator needs to change the position of the drawing board by rotating it for the sake of convenience. , however, the content of the page displayed on the computer does not rotate accordingly

The inventor finds that no relevant technical solutions are provided in the prior art to solve this problem
