Spatial Augmented Reality Illusions

The basic concept of Spatial Augmented Reality is to augment real physical 3D objects with virtual content. This approach allows displaying additional information or even changing the appearance of the physical objects. The (spatial) display is typically represented by the objects themselves and is therefore decoupled from the user. Hence, compared to traditional AR displays like head mounted displays or handheld devices, spatial displays solve several problems that are related to visual quality (e.g. the limited field of view), technical issues (e.g. tracking) and human factors (e.g. discomfort). Furthermore, a system based on SAR scales well to multiple users and therefore supports collaborative tasks naturally.

 

In this project we examine the usage of SAR camera-projector systems in different application-related settings. We develop both presentation and interaction techniques with a focus on 3D stereoscopic display of the virtual content. We also want to investigate how a persons's perception of his real world environment can be manipulated with SAR, for instance in terms of distance estimation.
