The ECS MultiTouch Driver is a device driver used for enabling and managing multi-touch functionality on touch-enabled devices, particularly those made by ECS (Elitegroup Computer Systems). These touch drivers enable features like gestures (e.g., pinch, swipe, etc.), touch input recognition, and proper communication between the operating system and the touch hardware (e.g., touch screen).
If you're using a laptop or desktop with a touchscreen display, this driver ensures that your device properly recognizes touch input and supports multitouch gestures such as zoom, scroll, and rotate.
