Bidirectional information transmission method, touch extension system and multi-point touch bidirectional extension equipment

Abstract

The invention discloses a bidirectional information transmission method, a touch extension system and multi-point touch bidirectional extension equipment. The bidirectional information transmission method includes monitoring graphic image information of specified positions, and analyzing and displaying the specified positions under a triggering condition; generating touch information, monitoring and automatically identifying the touch information, converting the identified touch information into touch signals, converting the touch signals into execution instructions and transmitting the execution instructions to compatible platform interfaces. A monitoring trigger module, an analysis and display module and a touch information generation module of the touch extension system are arranged on the multi-point touch bidirectional extension equipment, and an automatic induction and identification module, a touch signal conversion module and an interface module of the touch extension system are arranged on a target touch screen. Owing to the mode, the bidirectional information transmission method, the touch extension system and the multi-point touch bidirectional extension equipment have the advantages that functional extension effects can be realized for the touch screen, the touch extension system and the multi-point touch bidirectional extension equipment can be operated easily and conveniently, energy can be saved, and the bidirectional information transmission method, the touch extension system and the multi-point touch bidirectional extension equipment further can be applied to replacing a near field wireless communication technology.

Description

technical field [0001] The invention relates to the field of touch extension equipment, in particular to a two-way information transmission method, a touch extension system and a multi-point touch two-way extension device. Background technique [0002] The current multi-touch screen or touch panel is the mainstream configuration of computers and mobile phones, and there are trends such as single-machine multi-screen and gradually increasing area. However, a large number of devices still use Bluetooth, Wifi and other energy-consuming methods to connect to external devices. The frequency of user manipulation is low, and the touch extension device is basically in an idle state, and the use range and frequency of use of the larger touch screen are not uniform. That is to say, the way to use the touch screen for wireless operation has yet to be developed. The infrequently used or vacant area of ​​the touch screen also includes the use mode and application range of the touch exten...

Problems solved by technology

[0004] In addition, due to the expansion of applications, people nowadays can no longer be satisfied with using a single touch display device. When special analysis needs to be performed on a special area of ​​the display screen, the current method is generally implemented in the display through software. The area is processed on the entire screen, or a picture-in-picture is used to occupy a part of the display area to display the overall and local analysis at the same time, but both of the above have certain defects. One is that only local areas can be observed and cannot be coordinated. For comparison as a whole, the other is that the partial display takes up a certain amount of space, which makes the display of the whole part of the fixed display screen limited, and it is not easy to operate on any of them alone, or to operate on them as a whole at the same time
