4) Configuring screen settings. To correctly compute visual angle, saccade
amplitude, and eye velocity, the EyeLink eye tracker needs to know the physical
characteristics of your setup. Any time you change your physical configuration
(for example, if a new monitor is used, if the eye-to-screen viewing distance is
changed, etc.), you should use the Screen Settings configuration tool to ensure
that the parameters accurately reflect your current setup. The first three
parameters are important for all setups whereas the last parameter is important
only for Remote Mode use.
5) System Update - The EyeLink Portable Duo Host software installed on
the tracker can be updated through the "System Update" tool. First download
the latest version of the Host software from our support website http://www.sr-
support.com (go to "Downloads -> EyeLink Host Software -> EyeLink Portable
Duo Host software"). Start the "System Update" utility, select the Update tab
and click on the "Browse ..." button to locate the intended Host software
installer and then click "Update" button. Wait until the Host software is
updated – please be patient as this process may take a few minutes to
complete.
