# Session description

Each recording session is of a combination of the following parameters:

- Participants. We have recorded 16 people: 12 male and 4 female.
- Recording conditions. For participant 14, 15 and 16, some sessions were recorded twice, in two different conditions (denoted A or B): different day, illumination and distance to the camera.
- Visual Target. It is the object which the participant was requested to gaze at. To be representative of different applications, we included the following cases: Discrete screen target (DS), where a small circle was uniformly drawn every 1.1 seconds on random locations in the computer screen; Continuous screen target (CS), in which the circle was programmed to move along a random trajectory for 2s, to obtain examples with smoother gaze movement; 3D floating target (FT): a ball with a 4cm diameter hanging from a thin thread attached to a stick that was moved within a 3D region between the camera and the participant. In contrast to the screen target, the participant was at a larger distance (1.2m instead of 80-90cm) from the camera to allow sufficient space for the target to move.
- Head pose. To evaluate methods in terms of robustness to head pose, we asked participants to keep gazing at the visual target while (i) keeping an approximately static head pose facing towards the screen (Static case, S); or (ii) performing head movements (translation and rotation) to introduce head pose variations (Mobile case, M).

# Visualization

To inspect the different sessions please run the following command within the "Scripts" folder:

python view_session.py <session_idx>

Where *session_idx* is the session index ( [0, 93] ). By browsing through the code the user can find how to interpret the per session meta-data.

# Sessions list

Each session is denoted by the string "P-C-T-H" which refers to the participant P=(1-16), the recording conditions C=(A or B), the target T=(DS, CS or FT) and the head pose H=(S or M) respectively. The 94 provided sessions are the following:
