- In this study, we hypothesized that haptic feedback
would enhance grip force control of surface electromyography
(sEMG)-controlled prosthetic hands for targeted reinnervation
(TR) amputees. A new miniature haptic device, a tactor, that can
deliver touch, pressure, shear, and temperature sensation, allows
modality-matching haptic feedback. TR surgery that creates
sensory regions on the patient’s skin that refer to the surface of
the missing limb allows somatotopic-matching haptic feedback.
This paper evaluates the hypothesis via an sEMG-controlled
virtual prosthetic arm operated by TR amputees under diverse
haptic feedback conditions. The results indicate that the grip force
control is significantly enhanced via the haptic feedback. However,
the simultaneous display of two haptic channels (pressure and
shear) does not enhance, but instead degrades, grip force control.
