3.14 Experiment Practice

The TRACK.EXE program is the most flexible way to practice the EyeLink
tracker setup, allowing almost any sequence of actions to be performed. In real
experiments, the sequence of actions is much more defined. Usually the
experiment begins with participant setup and calibration from the Setup menu,
perhaps followed by practice trials. Then a series of experimental trials are
performed, sometimes with a drift correct before each trial.
This flow allows little room for practice, and makes it important that initial
setup and calibration be performed correctly and carefully validated. If tracking
issue develops in the middle of the experiment, users should consider going
back to the Setup screen (e.g., pressing ESC at the pre-trial drift correction
screen) to fix eye setup or calibration, and then continue the data collection.

3.15 Next Steps: Other Sample Experiments

For both Windows and Mac OS X, the EyeLink Developer's Kit contains several
sample experiments that are valuable demonstrations of how the EyeLink eye
tracker system can be used and programmed. On Windows, each sample
experiment can be launched from the "Start -> All Programs -> SR Research ->
EyeLink Examples -> C Examples -> GDI Graphics (or SDL Graphics)" menu
item. On Mac OS X, the examples can be run from "Applications -> EyeLink ->
SampleExperiments -> SDL".
All sample experiments have the following key shortcuts that can be used from
the Display PC keyboard. These keys are available after the experiment has
started and a Data File name has been entered.
