Video game controller for people with one arm

“Most amputees around the world live in places with limited or no prosthetic clinics nearby.”


The usage of upper limb prosthetics is not very high. According to an NIH study, documented rates of prosthesis use vary from 27 to 56 percent for upper-limb amputation. This is due to the fact that in the best case scenario, a conventional prosthetic arm offers only marginal functional improvements. This research was validated when I spoke to Gerald, who was born with his right hand missing. He confirmed that he had never used a prosthetic arm throughout his life, but mentioned having a few different attachments for performing certain activities. In most situations, he has learned to use his left hand and stump, including typing on a keyboard, which is the majority of his work, and other day-to-day tasks. He did mention having difficulty with certain recreational activities, like playing a trombone and using a game controller to play video games.

After several rounds of sketching, prototyping and form explorations, I modeled the final form using Rhino and 3D-printed it to make the final prototype. Please see photos of the design process below. The final design is not ambidextrous—a right-handed and left-handed versions would need to be manufactured separately.
