TAUCHI was established in 1995 by Prof. Räihä, at the same time when the first eye tracker was acquired. TAUCHI has grown into a unit of 40+ researchers that do research in a variety of topics within HCI, eye gaze being one of them. The gaze laboratory has already retired the first tracker which has been replaced by four trackers of different variety, two of them being Tobii eye trackers.

While the first eye tracker was acquired for usability studies, our lab has since been mostly used for basic research. Research using the Tobii trackers is being done on the following themes.

  • Gaze-controlled interactive applications. These include eye typing, especially feedback and its relation to dwell time (Majaranta, Ph.D. thesis, in progress) and MyTobii-compatible games developed at UTA by Oleg Špakov (shipped with the MyTobii installation CD-ROM and downloadable from the Tobii web site).
  • Attentive interfaces. Especially iDict: an attentive, gaze-based tool that assists in the reading of documents written in a foreign language (Hyrskykari, Ph.D. thesis, 2006).
  • Tracker-independent visualization tools for gaze data (Špakov, Ph.D. thesis, in progress).
  • Eye movement analysis. Domains include search-result interfaces (Aula et al., INTERACT 2005) and design products (Rantala et al., ECEM 2005).
  • Comparison of think-aloud and retrospective verbalization protocols with eye tracking (Lehtinen et al., in progress).
  • Combining eye-gaze with other physiological signals such as smiling or frowning for selection (Surakka et al., in progress).

TAUCHI collaborates with Tobii in two projects funded by the EU in FP6: COGAIN (COmmunication by GAze INteraction), a large Network of Excellence of 25 partners focusing on the use of eye tracking to serve the needs of users with disabilities; and EYE-TO-IT (Development of Human-Computer Monitoring and Feedback Systems for the Purposes of Studying Cognition and Translation), a STREP using keystroke logging, eye tracking and EEG in synchrony to study the cognitive processes of translation under time pressure.
