2 - 💡Intelligent Mouse Engine

Why we need an Intelligent Mouse Engine?

Trying to get a mouse working well on PS4, PS3, XBOX ONE, XBOX 360 is not an easy job.

● We need to find out the deadzone types and values, which are some strategies used by game designers to make controller stick a bit easier to operate.

● We need to countervail the special movement effect caused by different games and different game consoles.

● We need to make mouse control different games with the same feeling, at least as far as we could.

All these require professional knowledge and varied anlysis tools, and a long time of hard work and concentrated effort. And all these will not make a game enjoyable!

So we designed this Intelligent Mouse Engine based on the knowledge of Pattern Recognition to countervail all kinds of problems introduced by using a mouse on game consoles for different games. We analysed all the games and their differences on different consoles, collected tons of mouse input and output results on screen, put the mass data on the Artificial Neural Network (ANN), and train the ANN to get the most suitable method to conquer all the obstacles and bring a perfect shooting experience to our customers.

And the fruits we harvested:

● Simple for usage

● Steady while aiming

● Ease to draw a line or a circle

● Fast turning around

PC gamers are able to switch between a controller and a keyboard-and-mouse set instantly during gameplay. Thus, they can enjoy aim assist when aiming and firing (in controller mode), and they can also efficiently drop or equip weapons and attachments either from their backpack or a death box (in mouse & keyboard mode).

After PC gamers finish playing games, they can also switch to the keyboard and mouse mode with just one click to deal with daily computer tasks. There is no need to repeatedly plug and unplug the keyboard and mouse.

Connector A is a HID device, Connector B is a keyboard and mouse combo device, so control data can be sent from connector A to connector B to simulate a keyboard and mouse combo.
