Visual depiction of the experimental setup in the different experimental conditions. In the Face-to-Face (F2F) condition (a), triads of participants sit together on a physical table and perform the collaborative task together. In the collaborative Virtual Reality (VR) condition (b), each participant is placed in a different physical room, wears a head-mounted display, and is connected to the other participants via a local network connection. Each participant is represented via a personalized avatar created from photos of the participant. Camera-based hand-tracking is used to control the avatars fingers, and the body posture of the avatar is estimated using inverse kinematics based on hand and head location. Face- and eye tracking was not possible in this setup. In the Video Condition (panel c), participants are placed in separate rooms and perform the collaborative creativity task using a video conferencing tool. In all conditions, the participants perform the same collaborative creativity task.
