A 99$ eye tracker‘ & ‚Interaction research‘

| Am 11, Okt 2011

Am 07.11. spricht Youri Marko über die Entwicklung eines ‚low cost‘ eye tracker und deren Einsatzpotential, abseits der kostenintensiven kommerziellen Systeme. Im Anschluss wird Markku Turunen über Multimodal interaction research at ‚Tampere Unit for Computer-Human Interaction‘ (TAUCHI / Finland) sprechen.

Die Vorträge finden im Rahmen der Forschungskolloquien des Q&U Lab statt und kann von allen Interessierten Besucht werden.

Die Veranstaltung beginnt um 14:00 Uhr im TEL Auditorium 1&2 (20.Stock / Ernst-Reuter-Platz 7)


Offizieller Aushang:

A 99$ eye tracker

SPEAKER: Youri Marko

Eye tracking is a very exploited technology used in many different research contexts to probe perceptual and cognitive processes. However current gaze trackers are expensive and have strong limitations. Most commercial eye trackers are designed to observe the gaze patterns of users interacting with fixed digital monitors. In addition, the accuracy of these devises decrease rapidly if the subject move during the experiment.
As we were interested in analyzing gaze pattern of subjects interacting in a NATURAL way with PAPER documents, solutions that could potentially relax these limitations have been investigated. After testingdifferent remote setups, we built a wearable eye tracking device and tested it in a reading experiment on paper documents. The prototype is constructed with low cost off-the-shelf components. It integrates two cameras and an infrared LED in a pair of glasses. We used a hacked Sony Playstation camera to track the pupil of the subject and a commercial board camera to look at the scene and track the paper document.
The results obtained with this first prototype are very encouraging and show that we perhaps don’t need to spend several thousands of euros to buy an expensive commercial device in order to conduct eye tracking studies. We really hope that this device will inspire people coming from different fields and allow them to start working on new eye tracking projects.

Youri Marko is a research assistant in the/ Peripheral Systems Laboratory/ at /EPFL/ (/Ecole Polytechnique Fédérale de Lausanne, Switzerland/) where he works on printing techniques and color prediction models in order to develop new security solutions for printed documents. He obtained his Master of Science MSc in Microengineering in February 2011 at /EPFL/. During his Master Thesis („/Design of an Eye-Tracking System for Analyzing Reading Behaviours/“), he developed a 99$ eye tracker. Youri is particularly interested in human-computer interfaces, computer vision, design and image processing. He is currently looking for a challenging position where he could work on interdisciplinary projects.“

Interaction research (TAUCHI)

SPEAKER: Markku Turunen

I will present an overvirew of multimodal interaction research activities at the Tampere Unit for Computer-Human Interaction (TAUCHI). University of Tampere is one of the largest universities in Finland, with about 14.500 students. It is a full-scale university with nine schools. As a sizeable part of the School of Information Sciences, Tampere Unit for Human-Computer Interaction (TAUCHI) consists of 45 staff members. It is the largest research unit in its area in Finland and one of the largest in the world. The unit it has been identified as the „as the strongest Finnish group in HCI“ in the report of Academy of the Finland. TAUCHI is further divided into four research groups, Multimodal Interaction, Emotions, Sociality, and Computing, Speech-based and Pervasive Interaction Group, and Visual Interaction research Group.
I will introduce the research activities of these group, and provide some detailed examples from relevant case studies of the Speech-based and Pervasive Interaction Group.
