2.2 Modes of Operation
The EyeLink 1000 is a multipurpose, high resolution, real-time processing
system. It is designed to be used in 2 different operating modes:
Link: In this mode, the eye tracker can be controlled by the Display PC via
commands sent over the Ethernet link. The degree of Display PC control is
dependent only on the display application itself. With appropriate programming,
it is possible to have full control of the tracker via the Display PC. The SR
Research Experiment Builder software and various low level programming
interfaces have been designed to facilitate interacting with the Host PC. A
common scenario is to have the application on the Display PC control the eye
tracker to start subject setup and calibration, while the operator uses the
EyeLink Host PC's keyboard to remotely monitor and control data collection,
perform drift correction, and handle problems if they occur.
Standalone: In this mode, the eye tracker is an independent system,
controlled by the operator by the Host PC tracker interface and keyboard. The
Host PC is still connected to a display-generating computer for the purpose of
displaying calibration targets only. There are 2 possible data output modes
