Perception and Action in Virtual Environments (PAVE) Introduction of PAVE group

1. Perception and Action in Virtual Environments (PAVE)Introduction of PAVE group

2. Immersive Virtual Reality & Experimental Psychology • Immersive Virtual Reality equipment: Display + 3D computergraphics + bodymotiontracking • Methodologyofempiricalpsychology: Experimental design, measurementof human perceptionandaction

3. Social interaction I:Emotional Body Language Katya Volkova • Capture of body motions when expressing emotions • Animations based on motion capture data • Study on the perception of emotional body language: Participants are asked to categorize the animations by the emotions they express

4. Social interaction II: Non-verbalcues for predicting cooperation Dong-Seon Chang • Research question: Can non-verbal communicative social cues provide sufficient information to predict with whom we are going to cooperate well? • Capture of body motions when performing actions • Evaluation of perception of non-verbal cues • Prediction of cooperative action performance

5. Space perception:Using the body to perceive the environment Jeanine Stefanucci • Research question: How does the size and embodiment of a visual, virtual body influence space perception? • Affordance measures: Potential actions that can be carried out within the environment. • Participants are asked to judge, if they can fit through an aperture when seeing a virtual body with different sizes.

6. Body perception I:The perception of the physical body Aurelie Saulton • Research question: How do we perceive information about our body size and shape? • Pointing task: Point towards the felt location of the tip and knuckles of the fingers while hand is hidden. • Hand shape resulting from pointing task does not correspond to the shape of the physical hand. • Experiments on studieswiththepointingtask on theperceptionof a full (virtual) body.

7. Body perception II:The perception of a virtual body as oneself Ivelina Pryslopska • Research question: When do we notice that the dimensions of our body have been changed? • After watching a virtual body being simultaneously touched with their physical body individuals report to experience the virtual body as if it was their own body. • Experiments on theexperience of ownership over a virtual body with different volumes.

8. Multisensoryself-perception Martin Dobricki • Research question: Howistheexperienceofbeing ‘oneself’ generatedwithinmultisensoryperception? • Approach: Virtual body can be moved with the physical body as if it was the own body. Virtual body is on a distance or co-located with the physical body. • Psychophysical measurement of experiencing ownership over a virtual body on self-perception.
