HAPTIC FORCE-FEEDBACK FOR COMPUTING INTERFACES

摘要

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.

主权项

1. A haptic device comprising:
a housing; a actuation mechanical structure having: a ball partially disposed within the housing with a portion extending beyond the housing; a first motor and an associated first drive train in communication with the ball for rotating the ball about a x-axis; a second motor and an associated second drive train in communication with the ball for rotating the ball about a y-axis that is perpendicular to the x-axis; a gyroscope; a microcontroller in communication with a memory module, a communication module, the first motor and the second motor, and a power module.
