Virtual Reality

Knowledge Base → V

Virtual Reality is an attempt to use digital media (visual, audio, tactile) to portray a computer-mediated virtual world in a way that best fits our natural modes of communication.

A key feature of virtual reality is real-time interactivity, the ability to detect user inputs and modify virtual world instantaneously. These interactions involve not only 3D images but also the incorporation of 3D sound, artificial smell generation and force-feedback. Another key feature is immersion, which is defined as the feeling of being part of the action in the virtual world. According to Heim, who defined VR with ‘three I’s’, the third characteristic of VR is information intensity. Virtual world sends constantly updated information to users supporting immersion and interactivity. This knowledge transfer is referred as information intensity, which is the third I of VR, after immersion and interaction.

There are four major types of VR, categorized by intensity of immersion:

• Desktop VR station
• Cabin VR station
• Projection VR station
• Immersive VR
