Eye Tracking Pilot Accuracy and Precision Data

This file contains
accuracy and precision measurements and raw gaze samples taken from 12
participants in a real-world laboratory setting using Tobii X60, 60Hz Remote
Eye Tracker using manufacturer's I-VT filter settings. Stimulus was displayed
on a Dell 2209WA flatpanel display monitor at approximately 70cm viewing
distance  at a resolution of 1680x1050.

Accuracy
data was calculated against fixations on 9 points distributed across upper,
middle, lower, left, center, and right thirds of the display. Precision data
was calculated against a single fixation for each participant on a non-moving
object of focus centered in the display for three seconds' duration, resulting
in 80-150 raw gaze samples per participant, dependant on the speed with which
the participant was able to focus and fixate on the object.
