In an ongoing London exhibition, artist Graham Fink is using an eye tracker to draw portraits, live, using only his eyes. The eye tracker, provided by Tobii Technology, uses infrared light to track Fink’s eye movements. Those movements are then translated into lines on a screen. Tobii Technology trackers and software are more commonly used for assistive devices, games, and consumer research. Fink discusses the exhibition in this Creators Project interview. Fink’s live exhibit can be viewed at Riflemaker gallery in London through March 21, 2015.
