The EyeWriter is a low-cost eyetracking system originally designed for paralyzed graffiti artist TEMPT1. The EyeWriter system uses inexpensive cameras and open-source computer vision software to track the wearer's eye movements.
EyeWriter was conceived by Mick Ebeling and developed at Ebeling's home in Venice Beach by artists and engineers from the Free Art & Technology Lab, Graffiti Research Lab and OpenFrameworks teams, including Zachary Lieberman, Evan Roth, James Powderly, Theo Watson and Chris Sugrue.
The project has been recognized with numerous awards including being honored by TIME as one of the Top 50 inventions of 2010, the 2010 Prix Ars Electronica, the 2010 FutureEverything Award and featured on NPR and TED
EyeWriter was featured in 2009 at the CREAM International Festival for Arts & Media in Yokohama. TEMPT1 was also featured in 2009 projected on Kyoto City Hall. EyeWriter was part of the Talk to Me exhibit at MoMA on display from July 24 until November 7, 2011.
