Method, device and system for peripheral positioning on touch screen

Abstract

The invention discloses a method, device and system for peripheral positioning on a touch screen. The method includes the steps that point coordinate data of at least two induction anchors, making contact with the touch screen, of a peripheral is acquired; according to the point coordinate data and installation position information of the induction anchors on the peripheral, positioning point coordinate data of the peripheral on the touch screen and the inclination angle of the peripheral relative to the touch screen are calculated through a preset algorithm. By means of the method, the installation position, angle and other information of the peripheral on the touch screen can be precisely positioned; meanwhile, different varieties and model difference of installed peripherals are recognized according to different patterns formed by multiple induction anchor coordinates and different positions; besides, interaction between the peripheral and the touch screen can be achieved by movingone or more induction anchors, the complex situations that a mechanical method is fixed and equipment needs to be calibrated can be effectively avoided, users can conveniently conduct peripheral positioning, time is saved, and the use experience is improved for the users.

Description

technical field [0001] The invention relates to a method, device and system for external setting and positioning on a touch screen. Background technique [0002] A touch screen is a device that performs input positioning on the screen by measuring changes in pressure or electrical quantities on the screen. Touch screens have been widely used in smart phones, tablet computers, notebook computers and other devices. The current touch screen also supports a multi-touch function, that is, it can simultaneously sense and recognize the positions of multiple touch points. [0003] At present, devices that are precisely positioned and fixed on the touch screen are generally fixed by mechanical methods and need to be calibrated. However, this method has some problems as follows: the mechanical connection and fixing device for equipment fixing and positioning are complicated, and it is specially designed for the specific external equipment to be fixed and the appearance size of the t...

AI Technical Summary

Problems solved by technology

However, this method has some problems as follows: the mechanical connection and fixing device for equipment fixing and positioning are complicated, and it is specially designed for the specific external equipment to be fixed and the appearance size of the touch screen, and it is also difficult to disassemble and replace the peripheral equipment in the later stage. Complicated, not suitable for frequent disassembly and replacement of peripherals for touch screens

Because this method needs to use the structural features on the touch screen and the device for mutual positioning, it is generally only suitable for positioning between devices of a specific model size and the touch screen. When the size characteristics of the external device or the touch screen change, the design of the connecting fixture It also needs to be adjusted accordingly
