Description

Mouse device and method for detecting non-human mouse events through encryption

technical field

The present invention relates to a mouse device and its method, in particular to a mouse device for detecting non-human mouse events through encryption and a method for detecting non-human mouse events through encryption.

Background technique

Please refer to Figure 1, which is a schematic diagram of generating non-artificial mouse events.

A currently known cheating method for computer games is to collect the image signal of the computer device 10 (for example, a game screen) through the video acquisition device 12, and input the image signal to the analysis module 13 (such as a computer with a machine learning function or automatic identification function) computer).

Then, the analysis module 13 can analyze the image signal to find out the target position (such as the position of the enemy or treasure in the game screen), and automatically generate a corresponding non-artificial mouse event based on the target position (such as moving the mouse toward the target position) event), and send the non-artificial mouse event to the interface adapter 14.

In addition, an artificial mouse event is triggered when the user operates the mouse device 11 .

One end of the interface adapter 14 is connected to the computer device 10 , and the other end is connected to the mouse device 11 and the analysis module 13 .

The interface adapter 14 can send both the artificial mouse event (player action) generated by human operation and the non-artificial mouse event (cheating action) automatically generated by the analysis module 13 to the computer device 10 .

The computer device 10 will directly execute all received mouse events (including artificial mouse events and non-artificial mouse events).

Compared with player actions, the cheating actions automatically generated by the analysis module 13 are usually faster and more accurate, which makes the players who use the above cheating methods have a great advantage in the game, resulting in an unfair game.

Therefore, the above-mentioned problems exist in the existing mouse event processing, and a more effective solution is urgently needed to be proposed.
