We have developed a joint avatar of which two participants simultaneously control left and right-side limbs in first-person view in a virtual environment. We aimed to investigate whether having a common objective with a partner affects sense of embodiment towards a limb controlled by the partner. Participants performed reaching tasks using the joint avatar. We found that the embodiment towards the arm controlled by the partner was significantly higher when the participant dyads shared a common objective or when they were allowed to see their partner's goal, compared to when their partner's goal was unknown to them.
