Some frequently asked questions.

What is Virtual Reality (VR) ?


In a nutshell: VR is a computer technology that allows for real-time interaction and immersion into a digitally visualized reality in 3D stereo.


What does 3D stereo mean?


3D means three-dimensional – which means that objects are presented as spatial objects. Stereo 3D means spatial representation of two pictures. The procedure creating this effect is called stereoscopy – presenting pictures that create the impression of depth which does not exist physically. The pictures presented to the left and right eye by stereoscopy differ slightly in their angle. 3D glassed or auto-stereoscopic displays create the impression of spatial depth.


What is interaction?


Interaction is the dialogue between humans and machines in virtual reality. Thanks to a tracking system users can work by themselves or collaborate in a team to use and analyse the visualized 3D contents in real-time independent of where they are. COVISE or Cyber-Classroom are our standard virtual reality solutions that enables users to interact with different interactive devices like Wii Mote, a tablet or the Kinect.


What is immersion?


Immersion is a VR term used to describe the user’s state once he enters into a fictional world and is fully integrated into it. In 3D movies like for example the world wide success “Avatar” we experience “real 3D” as immersion. Thanks to our software this experience is now available in other areas as well.


What does the term “in real-time” mean?


Graphics technology allow for huge amounts for data that are necessary in 3D visualisation to be processed and visualized within split seconds. Users can experience immersive interaction “live” that is in real-time.


Why do I need 3D-glasses?


3D glasses enable you to see the two different pictures presented to your left and right by stereoscopy, creating an impression of depth. For this to happen, both pictures need to be processed simultaneously but separately by your brain. 3D glasses facilitate this process thanks to their filter. There are different stereoscopic procedures and consequently there are also different glasses. The most commonly used techniques are anaglyphs, polarization and shutter.


What’s the difference between shutter and polarization in 3D-displays and 3D-glasses?


Shutter technology creates alternating stereographic “semi-pictures”. Polarisation uses a different filter for light.


What is 4K and Ultra HD?


4K and Ultra Hd are terms used to describe the screen resolution. Both terms describe a resolution of 3840 x 2160 pixels, which is also called a quadHD resolution.


What do I have to look out for when using 3D stereo technology?



When we see things in stereo 3D our eyes need to move differently which might feel unusual at first. On the one hand we look at a screen on the other we look at a pictures that partly protrudes from the screen. Our eyes need to focus differently than in our normal "real" environment. In rare cases this can lead to eye pain, fuzzy view or headaches. To avoid this your eyes should be well rested before watching a 3D movie. It also helps to sit in the front-centre of the screen. If you are watching a 3D movie on TV make sure to have a distance of at least three times the screen height from the picture. In general most people adapt quickly and intuitively to 3D vision.
