Auditory Display as an Aid for Prosthetic Hand Manipulation: Preliminary Results
MetadataShow full item record
Upper limb amputees have to rely extensively on visual feedback in order to monitor and manipulate successfully their prosthetic device. This situation leads to high consciousness burden, which generates fatigue and frustration. Therefore, in order to enhance motor-sensory performance and awareness, sonification of the prosthetic hand's spatio-temporal and force information was implemented in a real setting. The main purpose is to explore the difficulties people face when using a prosthetic hand and how the usage of auditory information affects their performance. Preliminary results showed that the temporal performance and the grasping performance was improved, also that the mental effort was reduced, when using auditive feedback.
