Abstract
Haptic feedback refers to the external vibratory cue that is activated by data picked up by an Inertial Measurement Unit (IMU) that senses joint position (Figure 1). ❏ Position-driven haptic touch input can give feedback on movement in real-time (Meszaros, 2019) ❏ Original goal: to reduce knee hyperextension during gait using haptic-feedback driven by an IMU-based angle sensor (Sagemotion) ❏ Concerns arose on the validity of IMU/tactor to accurately sense joint position and past research identified a delay between IMU and joint position.
