Abstract

The present invention provides a method for realizing wireless infrared interaction, which includes steps: S110, collect moving infrared rays through a camera; S120, calculate the coordinates corresponding to the point on the screen according to the physical position of the point collected by the camera; S130, put The data of the coordinates are wirelessly transmitted to a computer or a display device with a built-in computer to realize human-computer interaction. The method and device for realizing wireless infrared interaction provided by the present invention senses the infrared rays touched by the camera and converts them into display coordinates to realize the human-computer interaction electronic whiteboard, which makes the circuit simple, low in cost, high in resolution, and transmits data through wireless, There are no restrictions on the use of original video products.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for realizing wireless infrared interaction. Background technique [0002] Human-computer interaction, also known as electronic whiteboard, there are two main types of existing technologies, one is the beam-to-beam infrared box method, the principle is that the quadrilateral box is filled with infrared sending and receiving tubes, and they correspond one by one. When there is an obstacle, such as when writing on the screen, the receiving tube cannot detect the infrared signal, and calculate the coordinates of the obstacle according to the current position of the infrared receiving tube. This method has complex structure, high cost and low resolution. Another kind of pressure-sensitive touch whiteboard, this kind of touch screen is divided into capacitive and resistive. The principle is that the whiteboard is full of capacitors or resistors. This change ca...

[0002] Human-computer interaction, also known as electronic whiteboard, there are two main types of existing technologies, one is the through-beam infrared box method, the principle is that the quadrilateral box is filled with infrared sending and receiving tubes, and they correspond one by one. When there is an obstacle, such as when writing on the screen, the receiving tube cannot detect the infrared signal, and calculate the coordinates of the obstacle according to the current position of the infrared receiving tube. This method has complex structure, high cost and low resolution

Another kind of pressure-sensitive touch whiteboard, this kind of touch screen is divided into capacitive and resistive. The principle is that the whiteboard is full of capacitors or resistors. This change calculates the coordinates of the pressing point. This method is difficult to achieve large-screen touch, the cost is high, and the touch screen is easily damaged during use.

The above two methods all use wired connection without exception. The human-computer interaction of the whiteboard in wireless video products has relatively large restrictions and is inconvenient to use.
