This year’s Eye Tracking Research and Applications Conference (ETRA2010) is held in Austin, Texas. This is the premier gathering event for eye tracking researchers worldwide. The very interesting keynote speech was given by Scott MacKenzie with focus on using the eye as a control device in human-computer interfaces. This was also the main topic of this year’s conference. As Dr MacKenzie described, the eye serves primarily as a sensor but using it to control computer interfaces (e.g. click on an icon by looking at it) is also possible. More and more research is devoted to this matter.
The poster session took place in the afternoon. I presented our poster that describes research on using pupil diameter measures to estimate the cognitive load of the driver. Lots of people were interested to hear that remote eyetracking can provide precise pupillometric data. The full text of our paper can be found here.
It was great to hear the feedback on our research by experts in the field of eye tracking. The bulk of the suggestions were focused on controlling lighting conditions, the change of which can induce noise in our cognitive load measures. We have already done mean illumination assessment of the driving scenario, which showed changes that were under 5%, but refining this assessment on the area where the subjects are focusing could provide even better proof of illumination not affecting the estimation of cognitive load.
The conference continues with exciting demonstrations, exhibitions and paper presentations. A must attend event for the eyetracking enthusiast.
