Virtual reality is a truly absorbing multimedia application. It is an artificial environment created with computer hardware and software. It is presented to the user in such a way that it appears and feels real. In virtual reality, the computer controls three of the five senses. Virtual reality systems require extremely expensive hardware and software and are confined mostly to research laboratories.
Another multimedia application is videoconferencing. Videoconferencing is conducting a conference between two or more participants at different sites by using computer networks to transmit audio and video data.
