People with prostheses are limited in their use of digital hardware: mouse, keyboard and touchscreen are not built to match their needs. However, amputees are often able to simulate movements with muscle control in their phantom limbs. Possibilities arise by creating a link between arm muscles and digital elements. Shortcut is a wristband that combines the movement of phantom limb with an optical sensor, creating contactless computer controlling. For example, tapping of a thumb and fore/middle finger, creates a left or right click, and snapping closes the active window.
This provides greater freedom in the workplace and beyond.
