VR technology development status and future trends are as follows:
A. VR technology development status:
Virtual technology is now maturing, and its application aspects are numerous. For example: medicine, games, military aerospace, interior design, real estate development, industrial simulation, cultural relics and monuments.
1, in medicine, virtual technology can establish a virtual human body model, through the tracking ball, feel the gloves and other tools, students can more clearly understand the structure of the internal organs of the human body, not only to improve the quality of teaching and learning, but also to increase the fun of the classroom.
2, in the game, three-dimensional games for the development of virtual technology provides a huge traction, and is also an important application of virtual reality technology, one of the sub-directions. Through the realization of three-dimensional games, compared with two-dimensional games, players can be more y integrated with the game, the sense of realism and immersion is greatly enhanced, such as Sony's PlayStation.
Second, the future trend of VR technology:
1, non-game content is getting richer and richer:
Currently, VR content is mainly occupied by games. This phenomenon is temporary. Games will not always be the mainstream of the VR content market, with the growing maturity of the technology, travel, concerts, movie content, etc. will gradually join the fray.
2, faster network:
The development of VR technology puts high demands on computer processing speed and network speed, which will have a far-reaching impact on Internet service providers and cloud storage service providers. Prompting them to carry out technological innovation and equipment upgrading.
3, smaller headset:
The headset devices on the market today are still a bit bulky and heavy for heavy use, and the design is also a bit weird. The arrival of graphics cards and cell phones with stronger processing speeds may allow VR headsets to become smaller and easier to use than they are now. As the technology evolves, VR tech is better able to create the full immersion needed.
4, education and training:
VR technology not only allows people in different spaces to appear in a virtual environment at the same time, but more importantly, VR provides a sense of immersion that can make education, training, and other programs more realistic.
The main features of VR technology:
1, Multi-Sensory:
The so-called multi-sensory refers to in addition to the visual perception of general computer technology, there is also auditory perception, force perception, tactile perception, motion perception, and even including taste perception, smell perception. Perception, etc. Ideal virtual reality technology should have all the perceptual functions that human beings have. Due to the limitation of related technology, especially sensing technology, the perception function of virtual reality technology is limited to visual, auditory, force perception, tactile perception, motion perception and so on.
2, immersion (Immersion):
Also known as sense of presence or sense of existence, refers to the user feels as the protagonist exists in the simulation environment of the real degree. Ideal simulation environment should make it difficult for users to distinguish the real from the fake, so that the user is fully engaged in the computer-created three-dimensional virtual environment, the environment looks real, sounds real, moving is real, and even smelled, tasted and so on, all the feelings are real, as in the real world, the same feeling.
3, Interactivity (Interactivity):
The degree to which the user can manipulate the objects in the simulated environment and the degree of naturalness of the feedback from the environment (including real-time). For example, the user can use their hands to directly grasp the virtual objects in the simulation environment, when the hand has the feeling of holding something, and can feel the weight of the object, the field of view of the object to be grasped can also be immediately with the movement of the hand and move.
4, conceptualization (Imagination):
Also known as autonomy - emphasizes that virtual reality technology should have a broad imagination space, can broaden the scope of human cognition, not only can reproduce the real environment, but also can be conceived objectively does not exist or even impossible to happen. The environment.
Generally speaking, a complete virtual reality system consists of a virtual environment, a high-performance computer as the core of the virtual environment processor, a helmet display as the core of the visual system, a speech recognition, sound synthesis and sound positioning as the core of the auditory system, an orientation tracker, a data glove and a data suit as the main body of the body orientation tracking equipment, as well as taste, smell, touch and force feedback system and other functional units. The feedback system is composed of functional units such as taste, smell, touch and force.
