Adaptive Haptic Training Protocols for Low-Cost Upper-Limb Prosthetic Controllers

Abstract

The study evaluates adaptive vibration cues for improving control consistency in myoelectric prosthetic training. A four-week protocol with twelve participants reduced target acquisition error by 19% compared with fixed-pattern feedback, with strongest gains in novice users. The paper contributes an open calibration routine and reflects on ethical considerations when collecting biometric interaction data from student participants.

Figure 8 compares fixed and adaptive haptic cue strategies across training sessions and participant cohorts.
