Tobii eye-tracking lab
Room 10, Oxley Hall
The Tobii eye-tracker is a stationary device with the eye-tracking component attached directly to the same unit as the screen. It is a bright-pupil system. Bright pupil systems use one or more lighting sources that bounce light off of the retina. You can see this kind of effect when you get "red eye" from a camera flash. Eye-tracking systems that use this technology detect the brightness coming off of the pupil to determine where the participant is looking. In the photo below, you can detect the infrared light sources being emitted from the bottom of the Tobii unit.
In Room 10, there are also 3 sound booths for training and/or other types of experiments. They are equipped with a computer running eprime, audacity, praat, and other software, a 5-button response box, and may contain a headphone and/or microphone with pre-amp, depending on who is using which sound booth for which experiments at the time.
ASL eye-tracking lab
Room 209, Pomerene Hall
The ASL eyetracker is a head-mounted device that allows multiple angles of viewing, i.e., multiple fixation screens. It uses a stationary receiver situated behind the participant. This style of eye-tracker allows the participant to move around and shift their focus between more than one screen or other target, or to examine multiple targets at different angles, and triangulates their location. It also allows for manual manipulation of objects rather than the standard mouse-click on the AOI. The ASL is also a bright pupil system.
