Ich leite zusammen mit Betty Mohler die Gruppe Wahrnehmen und Handeln in Virtuellen Umgebungen.
Unsere Gruppe besteht aus Technikern, Informatikern und Psychologen. Unser Hauptziel besteht darin die Methodik der empirischen Psychologie, insbesondere der Psychophysik, mit der Technologie der Immersiven Virtuellen Realität zu kombinieren, um (A) das Verständnis des menschlichen Wahrnehmens und Handelns und (B) die Integration der Technologie der Virtuellen Realität in die Grundlagenforschung, angewandte Forschung sowie in das tägliche Leben voranzutreiben.
When the perceptual field of individuals is reorganized such that they can see the projection of their body  or an avatar within virtual reality  being simultaneously touched at the same location, where their physical body gets touched, they start to identify with and localize themselves towards that virtual body. The fundamental principle of multisensory integration is that information from different sensory modalities is merged by the brain such that coherent and robust percepts are formed . Hence, the identification with and localization in a virtual body may be regarded as a result of this principle, which integrates tactile and visual information such that a coherent percept of oneself is generated. This principle of integration is at the same time a principle of differentiation. The formation of a perceptual unit that is oneself implicates the differentiation of this entity from everything that is not oneself, and thus the generation of the experience of being a distinct entity. In support of this we have found using a pharmacopsychological approach that changes in the experience of the boundaries of oneself go along with changes in the formation of visual percepts . Thus, regarding the experimentally induced identification with a virtual body, the question arises what happens to self-demarcation. One option is that individuals experience themselves within the clear boundaries of the virtual body. However, another option is that felt and seen touch are integrated such that their boundaries include their physical body and the virtual body. Hence, in this case individuals would incorporate an avatar, because the boundaries of what they experience as “themselves” get altered.
Investigate in the framework of multiple experiments under which conditions individuals’ self-boundaries get altered when they identify themselves with a virtual body.
Immersive Virtual Reality setups will be used in which healthy participants experience a virtual city (Virtual Tübingen). Within these setups in which participants view an avatar from different perspectives the effect of visuo-tactile integration and visuo-motor integration on the experience of embodiment, presence, face perception, and self-motion will be studied.
A first project on the effect of self-localization on the perception of visually induced circular self-motion is almost finalized, and will soon be published.
