Tiare Feuchtner.

Virtually extending the body in augmented reality. Wearing a head mounted display the user (right) can see a virtual arm in place of his own (left). This virtual arm can be extended to supernatural length to manipulate distant objects in the environment.

During her PhD studies, Tiare Feuchtner researched the body ownership illusion in Virtual and Augmented Reality. She has conducted experiments showing that the body ownership illusion can be leveraged to overcome the limitations of our physical bodies and to create more efficient and engaging interactions. The conviction that your physical hand is, in fact, your own hand is an example of body ownership. When this feeling is achieved for an artificial body part (e.g., a virtual hand) we speak of the illusion of body ownership.

The results of this research indicate that our mental body representation may be more malleable than was previously believed. For instance, humans can feel body ownership of an unnaturally long virtual arm or a virtual hand that appears in a different position and orientation relative to the body. While most approaches to VR and AR interaction design attempt to modify the virtual world with which we interact, Tiare proposes to instead augment the body we interact through - or at least our mental image thereof.

The PhD degree was completed at Department of Computer Science, Science and Technology, Aarhus University.
