My predisposition to eye tracking may or may not have become apparent in the following research…
1)Eye tracking controlling Head Mounted Microdisplay
Researches from Fraunhofer IPMS created a microdisplay that is mounted like a monocle, displaying augmented-reality like data and information. You can interact with the display simply by moving your eyes. http://www.engadget.com/2011/04/20/eye-tracking-microdisplay-delivers-terminator-vision-distracts/
2) Google using Eye Tracking as User Experience research
While developing Universal Search, Google used eyed tracking devices to look at where the eyes fall and how fast they scan results: http://googleblog.blogspot.com/2009/02/eye-tracking-studies-more-than-meets.html
3) Head Tracking creating “Fake 3D” on the iPad
Researches from the Engineering Human-Computer Interaction Research Group used the front facing camera on the iPad 2 to judge the position of the head — from there, they were able to create visual tricks and trompe l’oeil to simulate 3D on the iPad screen without the use of glasses. http://www.pcworld.com/article/224987/eyetracking_trick_brings_glassesfree_3d_to_ipad_2.html
4) A Cognitive Study using Eye Tracking to observe the Artistic Eye
I found this in “Cognitive Daily” — researchers performed a test having artists and non artists study a painting with the goal of remembering it while performing “unknown” eye tracking. The artists looked at the painting much differently than non artists — focusing less on key details. The study aimed to provide insight into the habits of artists and artistic training. http://scienceblogs.com/cognitivedaily/2007/03/artists_look_different.php
5) Dynamic Face Substitution by Arturo Castro and Kyle McDonald
This is using C++ and also a color algorithm to blend real-time video of a face with photos of celebrity faces: http://flowingdata.com/2012/01/04/face-substitution/ — the more research I did, the more I saw Mr. McDonald’s name. He is the originator of FaceOSC. His projects are really fascinating, overall — but I thought this was one of the more successful.
