EyeTech EyeOn

A video from EyeTech that features Michael who suffers from Thoracic Outlet Syndrome (TOS). Great little clip that shows what computer control without gaze-adapted interfaces comes down to. Luckily Michael can use voice recognition software for typing, text input using eye movements alone is a cumbersome process (source).

EyeDrone - Eye gaze controlled navigation



Demonstration for eye-gaze controlled navigation. The goal was to move the the point of gaze to the center of the screen, simply put "where you look is where it goes". This is the popular AR.Drone quadricopter controlled with this policy using an EyeLink 2000 eye-tracker. The drone pivots left and right when the operator looks into those directions. It tilts up and down (making it fly backwards and forwards) when the operator looks up or down. EyeDrone was implemented by Lucas C Parra in C++ with much help from Michael Quintian. The chin rest here is not really needed as the basic control algorithm is inherently stable and miscalibrations are of little concern.

Low Cost Eye Tracking for Commercial Gaming: eyeAsteroids and eyeShoot in the Dark!

Latest update from Stephen Vickers and Howell Istance at the Centre for Computational Intelligence, De Montfort University who have been doing research and development of gaze-based gaming for several years now. Their latest project has been shortlisted in the consumer category of The Enginner Awards 2011. Congratulations on an awesome job!

"Using your eyes and where you are looking to interact with computer games represents an exciting new direction that game play can take, following the success of whole body interaction enabled by the Kinect and the Wii. The Innovation Fellowship has supported the development and demonstration of a low-cost eye tracker by De Montfort University, in collaboration with Sleepy Dog, the East Midlands games company that produced the Buzz-it controller and games. The low-cost eye tracker utilised the ITU Gazetracking library and was produced as a fully working pre-production prototype. In the project, three different games were produced to demonstrate different ways in which eye gaze can be used to make game play more immersive and exciting.

This video demostrates two of them.
  • eyeAsteroids The ship flies towards where you are looking and the space bar is used to fire.
  • eyeShoot in the Dark! The torch shines at where you are looking and the mouse is used to move the cross-hair and fire.

SMI Glasses now available

The SMI Glasses, which we got a sneak-peak at before last Christmas and specs in April are now available for sale. SMI engineers have managed to squeeze two 30Hz eye tracking cameras and a high definition scene camera into the frame weighting only 75 grams. The advantage of tracking both eyes is that it enables parallax compensation where the accuracy is maintained regardless if you look close or far in the scene. In addition, binocular tracking most often yields better accuracy as it provides the opportunity to average both samples or to discard one with low validity. The HD scene camera captures 24 frames per second at 1280x960 pixels, a clear advantage. All in all, better late than never, SMI is back with a highly competitive product in the market.

LG introduces the world first Glasses-Free 3D monitor with eye-tracking technology

Today LG announced a 20" LCD display with built-in "eye tracking" technology that enables glasses-free 3D imaging which moves this technology closer to the consumer market. The image below does, as far as I can tell, not reveal any infrared illuminators, a requirement for all known systems with high accuracy so it's probably more of a rough estimation system than a full-blown remote system. Best known accuracy (published research) under natural light is about 3-4 degrees of angle, with their financial resources they could potentially achieve better results. 
Left. The "special" eye tracking camera sensor. Looks like a rather typical webcam CMOS sensor to me. Unless they are doing some magic it will not allow accurate gaze estimation. Regardless, makes me wonder if 3D displays is the path by which eye tracking goes mainstream? Is this related to the collaboration between Seeing Machines and SuperD announced earlier this year or just a competing solution? Details are sparse, I'll keep you posted as it becomes available. 


Official press release:


SEOUL, July, 13, 2011 – LG Electronics (LG) today unveiled the world’s first glasses-free monitor utilizing eye-tracking technology to maintain an optimal 3D image from a range of viewing angles. The 20-inch D2000 (Korean model: DX2000) monitor was developed as a fully functional entertainment display capable of reproducing games, movies and images in all their realistic glory.

“With a full line-up of 3D TVs, laptops, projectors and smartphones, LG Electronics is by far and away the industry leader in all things 3D.” said Si-hwan Park, Vice President of the Monitor Division at LG’s Home Entertainment Company. “LG’s position has always been that 3D will and must eventually function without glasses. The D2000 is a look at what the future has in store.”

The D2000’s 3D effect comes courtesy of glasses-free parallax barrier 3D technology, and the application of the world’s first eye-tracking feature to the monitor. The combination of parallax barrier and eye-tracking in a single unit promises to open up new horizons for glasses-free 3D products.


Existing glasses-free 3D technologies generally require viewers to stay within a tightly restricted angle and distance to perceive the 3D images. However, the D2000 has done much to resolve this issue, allowing viewer much freer movement and more comfortable viewing. Eye tracking in the D2000 works via a special camera sensor attached to the monitor which detects changes in the user’s eye position in real-time. With this information, the monitor calculates the angle and position of the viewer and adjusts the displayed image for the optimal 3D effect.

In addition to playing back existing 3D content, the D2000 has a highly refined 2D to 3D conversion feature which adds a new dimension to existing movies and game playing.

The D2000, available in Korea this month, will be introduced in other markets around the world in the latter part of 2011.

This video demonstrates the use of Ergoneers Dikablis Eye-Control Module used to interact with a standard LCD TV. The project was carried out in collaboration with Technical University of Munich and reminds me much of an ongoing research project at ITU Copenhagen.


Gliding and Saccadic Gaze Gesture Recognition in Real Time (Rozado, 2011)

David Rozado with the Department of Neural Computation at the Universidad Autonoma de Madrid have developed a neural network approach for detecting gaze gestures in real time. I met David at ITU Copenhagen last summer when he was visiting and discussed this research, I'm happy to see that it came out with such great results. This research was part of Davids Ph.D thesis which focused on Hierarchical Temporal Memory (HTM) neural network which is a bioinspired pattern recognition algorithm. Using a low cost webcam and the ITU Gaze Tracker he is able to recognize ten different gestures with 90% accuracy using raw data. When a fixation detection algorithm and dwell time triggers are employed it is possible to achieve 100% detection rates (at the expense of longer activation times).
