On July 16, 2019, NVIDIA filed a patent for a touch trackball gamepad. It should combine the precision of a mouse and the control of speed like a joystick. At least that ‘s what the patent description sounds like .
This is not the first time a trackball has been tried on a gamepad. The header shows work from the DufenTech enthusiast.
The gamepad is designed to create a universal controller for all games. The mouse can provide absolute precision, which is important in one type of game, and the joystick is useful for video games that require speed control, for example, where the greater the offset from the center of the joystick, the faster the cursor or camera in a video game will move in that direction.
The NVIDIA gamepad is capable of combining both the advantages of a mouse and a joystick. It can provide absolute mouse or trackball accuracy, but it is also capable of measuring how far from the center of the screen the cursor is located and can return to center when released like a joystick.
The patent says the disclosed game controller uses a touch trackball to take advantage of both mouse and joystick inputs in a single dedicated input, giving the user the freedom to play any type of game without worrying about the compatibility of their game controllers.
Unfortunately, it is unclear if the gamepad will go on sale or is it just a patent.
