ETRA 2010 Proceedings now online

The proceedings of the 2010 Symposium on Eye-Tracking Research Applications 2010, Austin, Texas March 22 - 24, 2010 is now online. Some kind soul (MrGaze?) decided to do the world a favor by uploading and keyword-tagging the papers onto the Slideshare website which is indexed by Google and other search engines. The wealth of information ensures days of interesting reading, several short papers and posters would have been interesting to hear a talk on, but as always time is short.

In the Eye of the Beholder: A Survey of Models for Eyes and Gaze (Hansen&Ji, 2010)

The following paper by Dan Witzner Hansen from ITU Copenhagen and Qiang Ji of Rensselaer Polytechnic Institute surveys and summarizes most existing methods of eye tracking and explains how they operate and what the pros/cons of each methods are. It is one of the most comprehensive publication I've seen on the topic and a delight to read. It was featured in the March edition of IEEE Transactions on Pattern Analysis and Machine Intelligence.

Abstract
"Despite active research and significant progress in the last 30 years, eye detection and tracking remains challenging due to the individuality of eyes, occlusion, variability in scale, location, and light conditions. Data on eye location and details of eye movements have numerous applications and are essential in face detection, biometric identification, and particular human-computer interaction tasks. This paper reviews current progress and state of the art in video-based eye detection and tracking in order to identify promising techniques as well as issues to be further addressed. We present a detailed review of recent eye models and techniques for eye detection and tracking. We also survey methods for gaze estimation and compare them based on their geometric properties and reported accuracies. This review shows that, despite their apparent simplicity, the development of a general eye detection technique involves addressing many challenges, requires further theoretical developments, and is consequently of interest to many other domains problems in computer vision and beyond."

GM Automotive heads-up display

General Motors today presents a new automotive heads up display system that has been developed in conjunction with Carnegie Mellon and the University of Southern California. It employs a number of sensors that coupled with object and pattern recognition could assist the driver by projecting information directly onto the windshield. For example the system could assist in navigation by highlighting road signs and emphasis the lanes/edges of the road in difficult driving conditions (rain, snow, fog). Inside the car the system uses an eye tracking solution provided by Swedish firm Smart Eye. Their Smart Eye Pro 5.4 employs several cameras (three in the demonstration, max 6) and infrared illumination to provide 6 degrees of freedom head tracking and 2D eye tracking, both with a (reported) 0.5 degree accuracy. The firm reports that the system provides "immunity to difficult light conditions, including darkness and rapidly varying sunlight" however to what extent this is true for direct facial sunlight remains to be seen. However, over time technical issues are to be overcome, its exciting to see that eye tracking is considered for everyday applications (in a not so distant future). They are not the only ones working on this right now.

Mobile Dias Eye Tracker

Remember the Dias Eyetracker that I wrote about last May? Today Diako Mardanbeigi, from Tehran in Iran, presents a new version of the Dias eye tracker that is low-cost, wireless and fully mobile. I'll let the video demonstration below speak for itself. Rumor has it that Dias has been in contact with the ITU GazeGroup for a potential continuation of his research. Time will tell.



"This is a low cost mobile eye tracker with a wireless and Light weight head mounted hardware. This system gathers eye movements and estimates the point of gaze during the performance of daily tasks. It can let you to assess the visual behavior of the person online and in real-time when he is doing a specific task. A mobile eye tracker has a wide variety of applications in several fields such as human factors, market research, consumer shopping behavior, sports, driving, reading, safety & training. "

PhD Defense: Off-the-Shelf Gaze Interaction

Javier San Agustin will defend his PhD thesis on "Off-the-Shelf Gaze Interaction" at the IT University of Copenhagen on the 8th of January from 13.00 to (at most) 17.00. The program for the event consists of a one hour presentation which is followed by a discussion with the committee, formed by Andrew Duchowski, Bjarne Kjær Ersbøll, and Arne John Glenstrup. Whereby a traditional reception with snacks and drinks will be held.

Update: The thesis is now available as PDF, 179 pages, 3.6MB.

Abstract of the thesis:

People with severe motor-skill disabilities are often unable to use standard input devices such as a mouse or a keyboard to control a computer and they are, therefore, in strong need for alternative input devices. Gaze tracking offers them the possibility to use the movements of their eyes to interact with a computer, thereby making them more independent. A big effort has been put toward improving the robustness and accuracy of the technology, and many commercial systems are nowadays available in the market.

Despite the great improvements that gaze tracking systems have undergone in the last years, high prices have prevented gaze interaction from becoming mainstream. The use of specialized hardware, such as industrial cameras or infrared light sources, increases the accuracy of the systems, but also the price, which prevents many potential users from having access to the technology. Furthermore, the different components are often required to be placed in specific locations, or are built into the monitor, thus decreasing the flexibility of the setup.

Gaze tracking systems built from low-cost and off-the-shelf components have the potential to facilitate access to the technology and bring the prices down. Such systems are often more flexible, as the components can be placed in different locations, but also less robust, due to the lack of control over the hardware setup and the lower quality of the components compared to commercial systems.

The work developed for this thesis deals with some of the challenges introduced by the use of low-cost and off-the-shelf components for gaze interaction. The main contributions are:

• Development and performance evaluation of the ITU Gaze Tracker, an off-the-shelf gaze tracker that uses an inexpensive webcam or video camera to track the user's eye. The software is readily available as open source, offering the possibility to try out gaze interaction for a low price and to analyze, improve and extend the software by modifying the source code.

• A novel gaze estimation method based on homographic mappings between planes. No knowledge about the hardware configuration is required, allowing for a flexible setup where camera and light sources can be placed at any location.

• A novel algorithm to detect the type of movement that the eye is performing, i.e. fixation, saccade or smooth pursuit. The algorithm is based on eye velocity and movement pattern, and allows to smooth the signal appropriately for each kind of movement to remove jitter due to noise while maximizing responsiveness.

Scandinavian Workshop on Applied Eye-tracking (SWAET) 2010.

The first call for papers for the annual Scandinavian Workshop on Applied Eye-Tracking (SWAET) organized by Kenneth Holmqvist and the team at the Lund University Humanities laboratory was just announced. The SWAET 2010 will be held in Lund, Sweden between May 5-7th. The invited speaker is Gerry Altmann (blog) from the Dept. of Psychology at University of York, UK and Ignace Hooge (s1, s2) from the Dept. of Psychology at Utrecht University, Holland.

Remote tracker and 6DOF using a webcam

The following video clips demonstrates a Masters thesis project from the AGH University of Science and Technology in Cracow, Poland. The method developed provides 6 degrees of freedom head tracking and 2D eye tracking using a simple, low resolution 640x480 webcam. Under the hood it's based on the Lucas-Kanade optical flow and POSIT. A great start as the head tracking seems relatively stable. Imagine it with IR illumination, a camera with slightly higher resolution and a narrow angle lens. And of course, pupil + glint tracking algorithms for calibrated gaze estimation.

ITU GazeTracker in the wild

Came across these two Youtube videos from students out there using the ITU GazeTracker in their HCI projects. By now the software has been downloaded 3000 times and the forum has seen close to three hundred posts. It's been a good start, better yet, a new version is in the makings. It offers a complete network API for third party applications, improved tracking performance, better camera control and a number of bugfixes (thanks for your feedback). It will be released when it's ready.







Thanks for posting the videos!

Nokia near-eye display gaze interaction update

The Nokia near-eye gaze interaction platform that I tried in Finland last year has been further improved. The cap used to support the weight has been replaced with a sturdy frame and the overall prototype seems lighter and also incorporates headphones. The new gaze based navigation interface support photo browsing based on the Image Space application, allowing location based accesses to user generated content. See the concept video at the bottom for their futuristic concept. Nokia research website. The prototype will be displayed at the International Symposium on Mixed and Augmented Reality conference in Orlando, October 19-22.
