Aimpad was founded by a passionate PC Gamer with the vision of wanting analog speed and direction, but not willing to give up the ridiculous number of configurable keys of the keyboard or the aiming precision of the mouse.
Most gaming keyboards are nothing more than flashy versions of a normal mechanical keyboard. It might have back lighting, or macro keys, but these enhancements do not make meaningful improvement in the way you control a game character or vehicle. The computer mouse, on the other hand, has evolved from using a ball, to an optical sensor, and finally a laser. These advancements in mouse technology have made an actual gaming improvement in the way we play PC games. We can aim with much better precision using a laser mouse than we can with a ball mouse. There have not been any similar improvements to keyboard technology that provide any meaningful improvement for controlling PC games until now.
