ABSTRACT
The sense organs (eyes, ears, skin, nose, and tongue) take in information, which is then sent to the brain for processing. They are the physical means by which all living beings communicate with the world around them. The ability to touch enables manipulation and active exploration that the other senses cannot. In a similar manner to how humans interact with the real world, visual, auditory, haptic, olfactory, and gustatory display can provide the natural and intuitive means of interaction between humans and the virtual environment created by a computer system.
