Sensing haptics in motion This project concerns haptic display for active people. Applications include motion training (e.g. for sports) and physical rehabilitation (e.g. relearning how to walk after surgery or to reduce joint strain). The most common form of portable haptic feedback is to use pager motors that produce vibratory signals. However, human sensitivity to vibratory feedback is usually lower during rapid motion. An alternative or complementary form of haptic feedback is skin stretch. The pages and links below report on experiments with each of these kinds of feedback for active users.

Skin stretch motion display

• Project overview -- Description of system combining optical motion tracking, computation of dynamic forces in muscles, tendons and joints, and haptic feedback to help users correct their motions.
• PortableSkinStretchSetup - skin stretch device as a possible haptic display for motions of the limbs

Haptics for gait retraining

• HapticsForGaitRetraining -- This project utilizes multiple pager motors and skin stretch for feedback regarding walking motions (gait, posture, trunk sway) with the goal of helping users learn how to walk so as to reduce knee joint loads and delay medial compartment knee osteoarthritis
