2.3.4.1 Purpose
Calibration is used to collect fixations on target points, in order to map raw eye
data to either gaze position or HREF data. Targets are presented for the
participant to fixate on the Display PC while feedback graphics are presented to
the experimenter on this display. The calibration is automatically checked
when finished, and diagnostics given.
Calibration should be performed after camera setup and before Validation.
The two camera images, along with threshold values, are at the bottom left of
the screen. The eyes to be calibrated as well as the calibration type (as defined
in the Set Options screen or via the EyeLink API) are indicated beside the
camera images at the bottom of the screen. The calibration status and current
calibration point being presented are indicated on the bottom right of the
screen.
