Chip on the Brain
Never mind touchscreens, keyboards, mice, or even voice input. The new BrainGate" technology cuts out the UI middleman by implanting a chip directly under a person's skull. The chip detects electrical impulses, which route to a computer for translation into real-world actions such as moving a cursor on screen, or opening and closing a prosthetic hand. Prototype BrainGate systems" are currently being tested on people with severe physical disabilities, including those with spinal-cord injuries or muscular dystrophy.
