In this topic, we would like to explore the concept of co-embodiment, the possibility for two or more VR users to be embodied into the same virtual avatar and to control its movements simultaneously. Recent experiments on co-embodiment focused on simultaneously controlling reaching and grabbing movements of an avatar. In this topic, we aim to go further and to explore the full range of co-embodied motions, from grabbing objects to moving the upper body to walking.

Within this topic, we focus on two types of avatars separately:

  • Human-like avatars: to control them, real movements of two or more users will need to be fused together. A concept for such fusion is demonstrated in the header image, from R. Fribourg et al., "Virtual Co-Embodiment: Evaluation of the Sense of Agency While Sharing the Control of a Virtual Body Among Two Individuals," in IEEE Transactions on Visualization and Computer Graphics, vol. 27, no. 10, pp. 4023-4038, 1 Oct. 2021, doi: 10.1109/TVCG.2020.2999197.
  • Non-humanoid or partially-humanoid avatars (multiple pairs of arms and legs, several heads, tentacles, tails - whatever you would like to contribute): here, each user might be responsible for controlling separate parts of the non-human avatar, with the full avatar motion being achieved only when all users contribute

We expect one student to work on the human-like co-embodied avatar and one student on the non-human avatar.


  • Literature research on embodiment and co-embodiment in VR
  • Design of a human-like avatar or a non-human like avatar
  • Design and implementation of methods for two (or more) users to be embodied into this avatar and to control its movements simultaneously


  • Knowledge of Unity3D
  • Previous experience of developing VR applications and especially multiplayer VR applications is advantageous
