A new conference on Novel Gaze-Controlled Applications will take place at the Blekinge Institute of Technology, Karlskrona (Sweden) on 26 and 27th of May (see conference page). The conference will focus on applications that make use of eye input and other biometric sensors, for instance games, eye-typing applications or social interaction applications. It will also explore new interaction methods using gaze interaction, and the challenges associated with eye tracking technology. The accepted papers will appear in the ACM Digital Library.
The two papers that we submitted were accepted for presentation in the conference. The title of the first paper is “Evaluation of a Remote Webcam-Based Eye Tracker”, and we conduct an exhaustive evaluation of the performance of the ITU Gaze Tracker in a remote setup and compare it to the Tobii T60 and the Mirametrix S1. In the second paper, “Gaze Interaction from Bed”, we explore how the ITU Gaze Tracker can be employed in a hospital scenario in which the patient interacts with an interface projected on a wall.
Update: papers now available
Nicolas Schneider has developed a head-mounted system to be used in in-vehicle scenarios as part of his Master Thesis project. The system employs an eye-tracking camera and a scene camera to record what the user is seeing, both mounted on a pair of glasses. The eye tracking software is based on the ITU Gaze Tracker v1.6, which has been modified to work in this setting. The results and accuracy obtained are impressive. We hope that Nicolas will contribute his software as open source, which will enable other enthusiasts and researchers to continue the work.
One of the main advantages of the ITU Gaze Tracker compared to most commercial systems is the high degree of flexibility it offers. Many commercial systems offer a compact solution in which all the components (camera, light sources) are built-in into the monitor. This can improve accuracy and head-pose invariance, but on the other hand makes the systems difficult to use in a non-desktop scenario.
We are currently working on a project together with Tokyo Institute of Technology to explore the possibilities of using gaze tracking systems in a hospital room. The small size of microprojectors and webcams allow the patient to interact with interfaces projected on walls or ceiling, giving him or her the possibility of controlling the environment and communicating with relatives or friends even when he or she cannot move due to a recent operation.
We started building a somewhat hospital-like environment in an open-space area we have in our new premises at ITU. The idea is to experiment with gaze interaction on different situations and projecting the interface on different surfaces (ceiling, a canvas, walls). We also plan to explore the difference between a close-up system using a webcam, and a remote system employing a videocamera.

Next week Henrik and I are visiting Tokyo Institute of Technology to further discuss with them the experimental setup and design that we should employ, and to run some initial tests. We’ll tell more about our progress soon!
