Interaction
Model and the traditional three-dimensional animation and virtual reality are usually generated by CAD systems is not the same, it is not a static world, but an open, interactive,virtual reality environment can influence by controlling and monitoring devices or users Effects, which is the second feature VR, i.e. interaction (Interaction).

Immersion
vAn artificial computer generated virtual environment, this virtual environment is a three-dimensional digital models constructed by computer graphics, programmed into a computer to produce realistic "virtual environment", allowing users to generate an immersive virtual environment visually the feeling, which is a sense of virtual reality technology immersion (Immersion) or spot a sense of participation

3.Imagination
Virtual reality is not just a demonstration of media,but also a design tool.It reflects the visual form designer ideas.Virtual reality can put this idea into a visible virtual objects and environments.
Defect
1.VR equipment is too expensive for ordinary people. 2.There are many inferior VR products which provide the worst virtual reality experience.It reduces the potential user's interest in VR. 3.Long time using VR equipment, users will feel giddy, disgusting.And it has certainly harmful to the eyes. 4.VR equipment volume is too big, complex ,and is not beautiful enough. It is difficult to Learning use VR for Senior

I- IV The difference between virtual reality and three-dimensional animation
Virtual Reality
Three-dimensional animation
A combination of digital virtual environment model based on real data from strict compliance with the standards and requirements of the project design, a scientific simulation systems. ? Manipulator experience the virtual threedimensional space, immersive.
Only one-way presentations as movie scene change, making the screen requires prior generation, time-consuming, laborious and costly.

Imagination
Virtual reality is not just a demonstration of media, but also a design tool. It reflects the visual form designer ideas, such as when the front cover of a modern building, the first thing you do is for the building's structure, beautiful idea to do detailed, in order to make quantitative, you need to many design drawings, of course, these drawings only insiders understand, virtual reality can put this idea into a visible virtual objects and environments, so that in the past only with traditional sand table design patterns upgrade to digital-per-view income that is perfection, greatly improving the quality and efficiency of the design and planning. This is the third category of VR has features that imagination (Imagination).

DEFINITION
• Virtual reality, referred to as VR technology, also known as artificial environment.
• The use of computers or other intelligent computing devices to simulate a virtual world of three degrees, providing users with visual, auditory, tactile and other sensory simulation, so that the user as immersive.
• A variety of interactive ways: combined with handle manipulation, behavior detection, speech recognition and other interactive ways to improve the user’s behavior even tactile interaction experience.

VR TECHNOLOGY WILL BRING THE AUDIO-VISUAL EXPERIENCE TO A NEW HEIGHT.

Increasingly Realistic Graphics
01
As graphics processing units (GPUs) and rendering technologies improve, VR experiences will become more photo-realistic, immersing users even further into virtual environments.
Entertainment Industry: VR has been widely used in the entertainment industry, providing users with an immersive experience in games, movies, and music.
Users are able to interact with the virtual environment using handheld controllers or other devices, and the system responds to their actions, creating a sense of presence within the virtual world.
要点三
Social Interaction
VR has the potential to redefine social interaction, allowing people from all over the world to come together in shared virtual spaces, enhancing global connectivity.
Controllers and input devices: These are necessary to interact with the virtual world. Controllers can be handheld, tracked gloves, or even full-body tracking suits depending on the type of experience and application.

—generates, at 20 to 30 frames per second, the ever-changing images
3.Tracking system
—continually reports the position and orientation of the user’s head and limbs
• VR display system must provide immersion
• Desktop displays are not considered to be VR – Hardly block out the real world – Do not present virtual world objects in life size – Do not create the illusion of immersion

Part3:the effect of virtua life
Although the social interactions of participants in virtual worlds are often viewed in the context of 3D Games, other forms of interaction are common as well, including forums, blogs, wikis, chatrooms, instant messaging, and video-conferences. Internet friendships and participation online communities tend to complement existing friendships and civic participation rather than replacing or diminishing such interactions.
