Description
Myoelectric prostheses have seen increased appli-
cation in clinical practice and research, due to their potential for
good functionality and versatility. Yet, myoelectric prostheses
still suffer from a lack of intuitive control and haptic feedback,
which can frustrate users and lead to abandonment. To address
this problem, we propose to convey proprioceptive information
for a prosthetic hand with skin stretch using the Rice Haptic
Rocker. This device was integrated with the myo-controlled
version of Pisa/IIT SoftHand and a size discrimination test
with 18 able bodied subjects was performed to evaluate the
effectiveness of the proposed approach. Results show that
the Rice Haptic Rocker can be successfully used to convey
proprioceptive information. A Likert survey was also presented
to the experiment participants, who evaluated the integrated
setup as easy to use and effective in conveying proprioception.
