Abstract

The invention discloses a writing method applied to an infrared touch screen, and the method comprises the steps: obtaining a shielding region of a touch point of a touch pen on the infrared touch screen in an infrared optical network scanning process; determining coordinate information of the touch point according to the shielding area; acquiring thickness information of the touch point by using the coordinate information; and sending the coordinate information and the thickness information to writing software, so that the writing software controls the infrared touch screen to display. The thickness information of the touch point is acquired by using the coordinate information; the thickness of strokes during writing is achieved through the coordinate information and the thickness information, writing of the stroke points can be truly restored and displayed according to the thickness information, the problem that in the related technology, a restoration note is distorted by simulating according to a related algorithm is solved, and the authenticity of displayed calligraphy content is improved. The invention further provides a writing device applied to the infrared touch screen, electronic equipment and a computer readable storage medium which all have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of touch technology, and in particular to a writing method applied to an infrared touch screen, a writing device applied to an infrared touch screen, electronic equipment, and a computer-readable storage medium. Background technique [0002] The infrared touch frame controls the emission and reception of the infrared light on the surface through a logic circuit, and captures the touch point by collecting and detecting the infrared light. The present invention uses the infrared touch frame to detect and calculate the touch point on the surface to obtain the information of the touch point Then report to the whiteboard writing software for processing and display the handwriting thickness of the font and the stroke of the brush characters, forming a real calligraphy effect written with brush characters. [0003] The related technology is to judge the thickness of the writing line by the rate at which the whitebo...
