Abstract
Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, provide two degrees of freedom active force feedback for touchscreens or any other general surface. The system includes a rubber ball attached to a pen-like structure with two motors that are capable of rotating freely when external force is applied. The system has also a mechanical structural arrangement including gears and cables to transfer motor power to engage the rubber ball. The system further includes a digital compass to measure the device tilt, along with a processing unit to control the system and a wireless communication module and a power module.
