Virtual Reality Lecture, by Michal Koutek
This lecture will describe Virtual Reality technologies and techniques that can be used for interactive data exploration and visualization. We will discuss aspects like VR perception, various VR display possibilities from techno-historical perspective, and some commonly used tracking technologies.
Then we will direct our focus towards how can be VR used for visualization of data, and what is its added value. This will finally lead us to the topics of 3D interaction and data exploration (VR) techniques.
We will prensent also a lot of video material with VR in use.
This lecture will be followed on the next day by a VR-VIS workshop in our VR-LAB: http://vrlab.tudelft.nl
