A project done during my BA, we were tasked to push the boundaries of upper-limb prosthetic design and to reach a concept that will have the potential to assist in design function. We worked with a transradial amputee who shared her experiences and gave us valuable information about the realm of prosthetics. We also talked to professionals who work closely with amputees.
We found that when you have a functioning hand paired with a prosthetic the prosthetic is primarily an assistant to the dominate hand. The hand handles the detailed work while the prosthetic holds, grips or secures. This led to the concept of a curling prosthetic.
