EyeLink Remote Hardware Adjustment for the Desktop Mount

The default version of the EyeLink Remote uses the Desktop Mount and an EyeLink 1000
High-Speed Camera programmed for Remote viewing. Users who are exclusively interested in
installing the EyeLink Remote should first follow installation instructions for the Desktop
Mount, then continue below.
To use the EyeLink 1000 in remote mode, the viewer is ideally about 60-70 cm from the display
surface. The height of the monitor should be set so that when the participant is seated and
looking straight ahead, they are looking vertically at the middle to top 75% of the monitor.
Once you have set up the system, make sure you have updated PHYSICAL.INI, which is located
at C:\EL1000\EXE folder of the Host PC. Please follow "Section 8.4 Customizing Your
PHYSICAL.INI Settings" to modify the PHYSICAL.INI file settings.
Check whether the camera is set to the Level position – the elongation of the camera should be
parallel to the table (see section 4.1 "Mounting the EyeLink 1000 High-Speed Camera"). Place
the eye tracker right in front of the monitor; the camera screw should be horizontally aligned to
the center of the monitor. To maximize the eye tracking range, the eye tracker should be raised
so that the top of the illuminator is as close as possible to the lower edge of the visible part of
the monitor without blocking the subject's view.
Internally, the eye tracker software was designed to perform based on this recommended setup.
Variability by a couple of centimeters will not have an impact on the tracker accuracy while a
larger deviation from the recommended settings may cause performance issues. Contact SR
Research for extra setup information if your experiment requires substantial deviation from the
above guidelines.
