Immersive technologies has the power to give us virtual bodies. Being in a virtual environment, looking at your virtual body and believing it is your own body is called body ownership illusion. In this talk, Tiare will give an introduction to how this illusion can be used and how far we can take it. What might happen, if users could interact with the virtual world just as they do with the real world, directly through their (virtual) bodies and how changing the body we interact with, rather than changing the virtual world or tools, could be used to improve virtual interactions. Research shows that what you perceive as your own body can change, based on what you see, feel, and believe. For example, under certain circumstances you might begin to feel that a virtual body, or part thereof, replaces your own physical body. This is called a body ownership illusion. In her research, Tiare explores how such body ownership illusions might be leveraged to overcome the limitations of our physical bodies and to create more efficient and engaging interactions.
For instance, you could feel body ownership of an unnaturally long virtual arm that allows you to interact with distant objects. Or you could "own" a virtual hand that appears to be reaching towards an overhead target, while your physical hand rests much more comfortably at waist-level. This enables new ways of interacting with virtual or augmented reality.
Consequently, while most approaches to interaction design attempt to modify the virtual world or tools with which we interact, Tiare proposes to modify the body we interact through instead - or at least our mental image thereof.
