Column descriptions

group_session

Group session ID

task

Task ID.

station

The iMac that the participant was stationed at.

participant

Participant ID. A participant ID of -1 indicates an unknown participant. All rows that do not have values for the `task` column will have their participant ID set to -1. In the future, we will label some of these inter/pre/post task rows with the correct participant ID.

timestamp_unix

The Unix timestamp of the event.

timestamp_iso8601

The ISO-8601 timestamp of the event.

confidence

Computed confidence between 0 (not confident) - 1 (confident).

norm_pos_x

X position in the eye image frame in normalized coordinates.

norm_pos_y

Y position in the eye image frame in normalized coordinates.

gaze_point_3d_x

X position of the 3d gaze point (the point the subject looks at) in the world camera coordinate system.

gaze_point_3d_y

Y position of the 3d gaze point (the point the subject looks at) in the world camera coordinate system.

gaze_point_3d_z

X position of the 3d gaze point (the point the subject looks at) in the world camera coordinate system.

eye_center0_3d_x

X center of eye-ball 0 in the world camera coordinate system.

eye_center0_3d_y

Y center of eye-ball 0 in the world camera coordinate system.

eye_center0_3d_z

Z center of eye-ball 0 in the world camera coordinate system.

eye_center1_3d_x

X center of eye-ball 1 in the world camera coordinate system.

eye_center1_3d_y

Y center of eye-ball 1 in the world camera coordinate system.

eye_center1_3d_z

Z center of eye-ball 1 in the world camera coordinate system.

gaze_normal0_x

X normal of the visual axis for eye 0 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

gaze_normal0_y

Y normal of the visual axis for eye 0 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

gaze_normal0_z

Z normal of the visual axis for eye 0 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

gaze_normal1_x

X normal of the visual axis for eye 1 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

gaze_normal1_y

Y normal of the visual axis for eye 1 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

gaze_normal1_z

Z normal of the visual axis for eye 1 in the world camera coordinate system. The visual axis goes through the eye ball center and the object that is looked at.

diameter0_2d

Diameter of the eye-ball 0's pupil in image pixels as observed in the eye image frame (not corrected for perspective).

diameter1_2d

Diameter of the eye-ball 1's pupil in image pixels as observed in the eye image frame (not corrected for perspective).

diameter0_3d

Diameter of the eye-ball 0's pupil scaled to mm based on anthropomorphic avg eye ball diameter and corrected for perspective.

diameter1_3d

Diameter of the eye-ball 1's pupil scaled to mm based on anthropomorphic avg eye ball diameter and corrected for perspective.
