Ideal timeline for the human's and robot's gaze during the teaching phase of the experiment, in the RI condition. The robot gaze (blue line) is moved toward the human head to look for eye contact. When mutual eye contact is established, in the RI condition the robot lowers the head to look at one of the objects on the table. The human, if engaged, follows the robot gaze (red line). When both partners look at the same object, the information exchange can take place. In this situation, the human can keep gazing at the object or look back at the robot for a confirmation (dashed lines).
