Haptic Guidance for Enhancing Human Motor Learning: Application to a Robot-Assisted Powered Wheelchair Trainer

This presentation will focus first on the study of the conditions under which robotic guidance seems effective for helping learn motor tasks such as steering a simulated wheelchair and learning a pure timing task (a pinball-like task). Haptic guidance enhances learning of timing tasks, such as driving and pinball, in less-skilled people, and is more beneficial when applied only as needed. Second, we describe the development of a robotic wheelchair trainer on which people with a disability can safely develop driving skills at their own pace with minimum assistance from a therapist. The concept was to equip a powered pediatric wheelchair with a webcam to achieve a self steering function along a course, and a force-feedback joystick to implement an algorithm that demonstrates exemplary control to follow the course, while systematically modulating its strength based on performance errors.
