Abstract: The goal of our demonstration is to illustrate how the haptic, force feedback device, can be used to assist people with disabilities in learning fine motor tasks, such as writing. We will be demonstrating this idea by the simulation of several letters and symbols. We use electromagnetic sensors (MotionStar Wireless2) to capture unencumbered movements performed by a 'normal' individual. The captured movement is translated to the haptic coordinate system with the use of a table-top centered frame as an intermediate frame. The translated movement is then fed into our haptic system, which varies the exerted force as a function of trainee performance. Our demonstration will use the Phantom Omni for the simulation of these writing tasks, and it will also provide visual feedback of the desired and user trajectories.
