In order to effectively create a 3-D environment for the user, virtual reality combines the elements of immersion and interactivity. Immersion is the user's contact with the virtual reality with as many senses as possible including; sight, hearing, and touch.
It is noted from the studies that speaking is very important for conveying different expressions. Moreover, many psychologists have found out that facial expressions resemble the emotions and attitudes of different people. Hence, in order to improve the systems to produce effective facial expressions, it is important to understand such a language. Computer facial animation is mainly a part of Computer Graphics that binds techniques and models to produce and animate human face and head. It is also associated with the fields like traditional animation and psychology because of its subject type and productivity.
The definition of virtual reality comes, naturally, from the definitions for both ‘virtual’ and ‘reality’. The definition of ‘virtual’ is near and reality is what we experience as human beings. So, the term ‘virtual reality’ basically means ‘near-reality’. This could, of course, mean anything but it usually refers to a specific type of reality emulation. Also, virtual reality is the term used to describe a three-dimensional, computer generated environment which a person can explore and interact with.
Introduction At the beginning, virtual reality try to make people understand that itself has the ability for a great medium, new entertainment and also very powerful type of art (Bates, 1991). Besides, according to Encyclopedia of Virtual Environments, 2006, they defined the virtual reality is a human-computer interface in which the computer creates a sensory-immersing environment that interactively responds to and is controlled by the behavior of the user. Virtual reality is popular in many areas such as education, architecture and entertainment. The most noticeable in virtual reality is in entertainment application. Through the idea that was presented by Ivan Sutherland, 1965, virtual reality can mimic our real life to make the world look real, sound real, feel real and realistically to the viewer’s actions.
1 INTRODUCTION: Haptics is a recent enhancement to virtual environments allowing users to “touch” and feel the simulated objects with which they interact. Haptics is the science of touch. The word derives from the Greek haptikos meaning “being able to come into contact with”. The study of haptics emerged from advances in virtual reality. Virtual reality is a form of human-computer interaction (as opposed to keyboard, mouse and monitor) providing a virtual environment that one can explore through direct interaction with our senses.
The often hardware are use in virtual reality which are Head Mounted Displays, glove, stereoscopic displays will make user feel of in virtual world when they use these hardware’s although they in real world. Technological development in virtual reality 3D help many area like education, medical, surgery, manufacture, military, architecture, entertainment, prototype and so on.

Besides, virtual chemical laboratory can be correct alternative to real laboratory in order to guarantee of user, insufficient chemical tools and poor real laboratory condition may be in danger.

ìOne thing is for certain: the information revolution is changing our lives, and we need to prepare ourselves to cope with its promise and potential.î [Gore 1991] How might VR help? Virtual Reality as a Learning Environment Using a head-mounted audio-visual display, 6-D position sensors, and tactile interface devices, we can inhabit computer-generated environments. We can see, hear and touch virtual objects. We can create, modify and manipulate them in much the same way we do physical objects, but without those pesky real-world limitations. VR is not only virtual: we can meet real people in virtual worlds, we can tele-exist in real places all over the world and beyond, and we can superimpose virtual displays onto the physical world.
We would define Virtual Reality as a way for humans to visualize, manipulate and interact with computers and extremely complex data. The visualization part refers to the computer generating visual, auditory or other sensual outputs to the user of a world within the computer. This world may be a CAD model, a scientific simulation, or a view into a database. The user can interact with the world and directly manipulate objects within the world. Some worlds are animated by other processes, perhaps physical simulations, or simple animation scripts.
It allows the consumers to enter a simulated world or experience by gazing through a specially designed headset. In the reality, we are in right now, we understand it through the main senses we have. The main five senses we have are sight, smell, touch, hearing and taste. The senses allow humans to perceive the world as we know it. So, with virtual reality it involves our senses to understand the computer-generated environment and with that, we can explore that world in some form.
They can create virtual humans with the natural gesture and face expression. It also can make an emotionally expressive head and body movement. Through these things, we can start to recognize the functions of the virtual human model. THE SIGNIFICANT CONTRIBUTION of VIRTUAL HUMAN MODEL to THE BODY of KNOWLEDGE The sig...
