Abstract

Myoelectric prosthesis users have altered spatial and temporal allocations of gaze, likely influenced by both control proficiency and sensory feedback. Providing task-relevant and movement feedback can improve spatial visual allocation, but temporal patterns of gaze shift have not been reported for prosthesis users with sensory feedback systems. We present data from two prosthesis users with integrated touch and kinesthetic feedback in a myoelectric prosthesis performing a functional cup movement task while tracking eye and hand movements. Despite different skill levels and task performance, both participants showed improved ability to disengage eye fixation from the object and transition to the next movement plan when provided kinesthesia and touch feedback together. Temporal allocation of gaze, specifically, the ability for the eye to disengage after interacting with objects, seemed impervious to skill level and maybe a valuable measure of the ability to trust the sensory feedback, disengage vision, and motor plan forward in a sensorized prosthesis. Eye latency measures could be a valuable marker of control skill and feedback efficacy in prosthesis users.
