Abstract

The invention provides a writing brush tip determining method and device based on infrared touch and a touch screen system. The method comprises the steps that area information of each touch point is determined when a user touches a touch screen; according to the area information of each touch point, the writing type width of each touch point is determined; according to the preset ratio value of the writing type width to the stroke thickness, the stroke thickness corresponding to the writing type width of each touch point is determined. Accordingly, when the touch area of the user is displayed, the writing type width of each touch point is determined according to the area information of the touch point, then, different writing type widths area determined according to different touch strengths, and different stroke thicknesses are obtained. The touch screen produces area information of each touch point according to the touch strength of the user and displays the corresponding stroke width, so that the stroke thickness displayed by the touch screen is variable, the writing effect is improved, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a method, device and touch screen system for determining a stroke based on infrared touch. Background technique [0002] A touch screen is an electronic system that can detect the presence and position of a touch within the display area. The infrared touch screen has the advantages of strong environmental adaptability, longer life, and more identifiable touch points. The infrared touch screen judges the user's touch behavior according to the different forms of the formed optical network under touch and non-touch conditions. [0003] In the prior art, the touch screen adopts an infrared point positioning algorithm to obtain touch points according to the orthogonality of the blocked optical path in the forward scanning direction of the long and short sides, and then form strokes, and then display the strokes formed by the user's touch. [0004] However, in the prior ...
