Abstract

The invention relates to an optical pressure-sensitive type drawing board system which comprises an input board, at least one image sensing device, an information processing unit and a light-emitting pen. The light-emitting pen can emit the light with different intensities according to the suffered different pressures of a pen tip in the drawing process while being used for drawing on the input board. The at least one image sensing device is arranged around the input board and used for sensing the light emitted by the light-emitting pen and the light intensity thereof and converting the sensed information into an electrical signal to be transmitted to the information processing unit, and the information processing unit is used for positioning the input of the light-emitting pen according to the signal and simultaneously judging the thickness change of the input handwriting of the light-emitting pen according to the change of the signal.

Description

technical field [0001] The invention relates to a drawing tablet system, in particular to a drawing tablet system which can be applied to an optical pressure-sensitive drawing tablet. Background technique [0002] At present, the drawing board systems that have appeared on the market are divided purely from the technical principle. There are three main types, namely, resistive pressure boards, capacitor boards, and currently popular electromagnetic pressure-sensitive boards (such as Wacom series drawing boards). The technical principles are as follows. [0003] The resistance board, known as the most primitive handwriting board, is composed of two layers of resistance films on the surface of the handwriting board. The upper resistance film can be slightly deformed, and the lower layer is a fixed resistance film. The stylus touches the upper resistive film and deforms it, and then contacts the lower resistive film, so that the position of the stylus can be determined. The w...
