Title
(EN) Screen touch positioning method and positioning system
(ZH) 屏幕触控定位的方法及定位系统
Abstract
(EN) The invention provides a screen touch positioning method and a touch system. Corresponding coordinate system establishment, the distance between the origin of coordinates and the touch point is measured; the coordinate points under the coordinate system formed by the touch points and the origin of coordinates are obtained according to the touch points and the included angle relation between the touch points and the coordinate axes, then the position points of the touch points on the touch screen are determined, and the positioning method is not only suitable for a flat panel display screen, but also suitable for various types of screens such as a special-shaped screen, and is accurate in positioning.
(ZH) 本揭示提供一种屏幕触控定位的方法及触控系统,通过建立相应的坐标系,并且测定坐标原点与触控点之间的距离,以及触控点与坐标轴之间的夹角关系,从而得到触控点与坐标原点形成的坐标系下的坐标点,进而确定触控点在触控屏幕上的位置点,该定位方法不仅适用于平面显示屏,还适用于异形屏幕等多种类型屏幕,并且定位精确。
