Left: One frame taken from the eye tracker videos (the eye video was imposed over the scene video on the top left corner). The bulls-eye shows the participant’s gaze landed on the model which was positioned at 90$∘$ to the participant’s right hand side. Right: The time series of eye (upper) and head (lower) rotations in degrees, with positive values on the y-axis indicating rotations to the observer’s right. The x-axis is time with positive values indicating the future and negative values indicating the past. The red vertical lines mark the current time (0), which corresponds to the video frame shown on the left.
