VIDEO-BASED EYE-TRACKING

Dr. Trueswell's lab has also been conducting research using the Head-Mounted Eyetracking Lab housed at the Institute for Research in Cognitive Science.

In this research, we have been monitoring people's eye movements as they listen to speech. The eyetracker (shown above) is a video-based system that uses miniature cameras and is worn as a light-weight visor on the head. Two cameras are used, one trained on the eye and one trained on the scene, as seen by the subject. The scene camera records the general direction that the subject is looking. The image from the eye camera is analyzed by a computer and, in real time, plots a point on the scene image indicating the current direction of gaze.

Current experiments examine the time-course with which people interpret speech, by examining how people actively interrogate the world as they hear verbal instructions to move objects.

We are also conducting research using a child version of the visor to study language processing in children.
