ASL Model R6 is a complete eye tracking system to use in situations where the stimulus presented to the subject is restricted to a single surface such as a computer or video monitor and where head mounted optics are not desirable.  The system allows the subject approximately one square foot of head movement which eliminates the need for head restraint.

Bright pupil technology, giving superior capture and contrast Software development Kit, which provides access to eye tracker controller port, serial out port and data files recorded by ASL interface program.  Works with Excel and MatLab.  Additional interfaces in process for ePrime and Presentation. Very fast and accurate head movement compensation. Autofocuses (50/60 Hz model only) The only optics system with a remote control    Allows user to determine number of calibration points to display Allows recalibration of a single point w/o having to start over System includes autodiscrimination and autocalibration

Data Output

The Model R6 is designed to measure a subject’s eye line of gaze with respect to a single stationary surface in the environment.  This measurement is displayed as a cursor or set of cross hairs superimposed on the image from a remote mounted scene camera or other video source showing the subject’s field of view.  A videotape of this image can be created as a permanent record.   A second camera displays a wide angle view of the subject and may be used to quickly locate the eye.  This wide angle view of the subject may also be recorded.

Recorded data include time, x and y eye position coordinates and pupil diameter.  External data events/marks can be recorded along with eye tracker data.  Eye position coordinates correlate to specific areas on the surface being viewed.  If the Model R6 includes an optional head tracker, head position and orientation can also be recorded.

Model R6 EYEPOS operating software provides the system operator with the ability to enter calibration and subject data and specify the operating parameters of the Model R6.  EYEPOS also converts the eye tracker data records into ASCII format for transmission to other computers or to off-line spreadsheet analysis.  Data is available, realtime, directly from the Model 6000 control unit through a serial port (RS232) in both an analog and digital format.  The Model R6’s interface PC can be connected to an Ethernet network, permitting data analysis form remote locations.

Included with the system is ASL's EYENAL and FIXPLOT data analysis software.  Additional software is available to integrate stimulation display and track scrolling web pages.
