Immersive VR
Knowledge Base → IImmersive VR is an artificial computer-mediated environment where the user feels part of the simulated environment and interacts with it.
To create a sense of full immersion, the 5 senses must perceive the computer-simulated environment to be physically real. Special immersive technology is used to perceptually fool the senses such as:
- Panoramic 3D displays (visual)
- Surround sound acoustics (auditory)
- Haptics and force feedback (tactile)
- Smell replication (olfactory)
- Taste replication (gustation)
Once the senses believe the digital environment is real, the user must then be able to interact with the environment in a natural, intuitive manner. Various technologies such as gesture & facial recognition and motion tracking respond to the user's actions and movements. Brain control interfaces (BCI) such as BOSLAB respond to the user's brainwave activity.
Immersive VR uses a variety of input devices and displays for user interaction with the virtual world. Input devices include:
- Desktop devices such as spaceball, spacemouse
- Positiontrackers
- Combined dev ices (Wanda: combines joystick + buttons AND positiontracking; TrackMan: trackball + knapper (but without positiontracking)
- Gloves such as CyberGlove, 5dt glove
Displays can be categorized into two types:
- Full immersive displays to include:
HMDs, BOOM and 6-sided CAVEs are FULL immersive displays because they in their basic construction surround the user completely. Full immersive displays allow only a limited number of users at the same time.
- Partial immersive displays
- 3-5 sided CAVEs
- Panorama, Powerwalls
- Monitors
3-5 sided CAVEs, Panorama, Powerwalls and monitors are PARTIAL immersive displays becaust they only surrounds the user (s) partially (when you turn around there is no display). Partical immersive displays allow for a large number of simultaneous users.
