The Institute of Physics (IOP) created a cost-effective device designed to allow people to play pong using just their eyes.
Patients who suffer from mobility impairment such as multiple sclerosis and Parkinson's can now enjoy certain games at a low cost. IOP reveals that the GT3D, which allows users to play pong using only their eyes, was created using simple and affordable off-the-shelf materials: two video game console cameras and a pair of glasses.
The cameras are attached on the outside the line of vision to monitor the eyes' movements by constantly taking photos of its directional changes. Logging in these changes, the system can quickly calculate where the game pieces are being directed. Scientists believe that this method can help create a system where prosthetics and wheelchairs can be controlled with the mind, which would be a tremendous breakthrough for the field.
