The Eyewriter 2.0 is a low-cost eye-tracking apparatus and custom software that allows graffiti writers and artists with paralysis as a result of Spinal Cord Injury (SCI) or Amyotrophic Lateral Sclerosis (ALS)  to draw using only their eyes.

 

Technical Specifications: 
  • Step 1: Overview
    • First, you will be making LED illuminators for the sides of the screen and the center. Second, you will be hacking the PS3 eye camera to get the vertical sync (when the frame of video is being taken) and to make it sensitive to IR. Third, you will be programming and building the Arduino / circuit to control the blinking. Finally, you will set the base for the system and go through the basics of the software.
