It also allows for manual manipulation of objects rather than the standard mouse-click on the AOI. 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. The user has to wear a light tracking helmet on his head, which does not interfere at all with any head movement. This tracker can provide detailed recording of eye movement even in a very short distance. It uses a stationary receiver situated behind the participant. When detail and accuracy are of the essence, the ASL static eye tracker offers the solution. The ASL eyetracker is a head-mounted device that allows multiple angles of viewing, i.e., multiple fixation screens. ASL eye-tracking lab Room 209, Pomerene Hall 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. The detector traces two characteristics of the eye: the cornea reflexion and the eye pupil. In Room 10, there are also 3 sound booths for training and/or other types of experiments. Eye Tracking is the process of recording the eye movements using a detector (an Eye-Tracker). In the photo below, you can detect the infrared light sources being emitted from the bottom of the Tobii unit. Eye-tracking systems that use this technology detect the brightness coming off of the pupil to determine where the participant is looking. It presents a simulated crime scene case study that applies eye tracking-based experiments in foraging and sense-making loops to elicit and represent knowledge on expert versus novice search patterns for complex work. You can see this kind of effect when you get "red eye" from a camera flash. Using eye tracking as a CTA methodology, this article explores visual search patterns in complex work environments and situations. Also attached to the headband is a small sensor from the magnetic head tracking unit. The camera unit is positioned above the subject's left eye, and a monocle is positioned just below the eye. The new streamlined design features easier access and recognition of important controls, more intuitive feature organization, and more compact windows. The ASL eye-tracking apparatus consists of a head-mounted camera and optics unit attached to a headband.

Bright pupil systems use one or more lighting sources that bounce light off of the retina. The Eye-Trac 6 User Interface Software is a redesign of the ASL eye tracker control software designed for easier setup, configuration, and operation. The ASL consists of a pair of modified glasses with an inward facing infrared camera and an outward facing camera, similar to the Pupil tracker. The Tobii eye-tracker is a stationary device with the eye-tracking component attached directly to the same unit as the screen. The ASL tracker is a head mounted eye tracking system that works in real time. Tobii eye-tracking lab Room 10, Oxley Hall
