Description
Technical field
This utility model relates to a kind of display device based on virtual reality glasses.
Background technology
Virtual reality technology is a kind of can to create with the computer simulation system in the experiencing virtual world it and utilize computer to generate a kind of simulated environment to be the interactively Three-Dimensional Dynamic what comes into a driver's of a kind of Multi-source Information Fusion and the system emulation of entity behavior makes user be immersed in this environment.
Virtual reality technology is that an important directions of emulation technology is emulation technology and the set of the multiple technologies such as computer graphics human-machine interface technology multimedia technology sensing technology network technology is a challenging interleaving techniques front subject and research field.The rich simulated environment to be included of virtual reality technology (VR), perception, natural technical ability and sensing set the aspects such as each.Simulated environment is generated by computer, the 3 D stereo photorealism of Real-time and Dynamic.Perception refers to that preferable VR should have the perception that all people are had.In addition to the visually-perceptible that computer graphics techniques is generated, the perception such as also audition, sense of touch, power feel, motion, the most also include olfactory sensation and the sense of taste etc., the most perception.Natural technical ability refers to the head rotation of people, eyes, gesture or other human body behavior acies, computer process the data that the action with participant adapts, and real-time response is made in the input to user, and feed back to the face of user respectively.Sensing equipment refers to three-dimension interaction equipment.
Virtual reality is the comprehensive of multiple technologies, including real-time three-dimensional computer graphics techniques, Radix Rumicis (wide the visual field) stereo display technique, the tracking technique to observer's head, eye and hands, and sense of touch/power feel feedback, stereo, network transmission, phonetic entry export technique etc..Below these technology are illustrated respectively.
Real-time three-dimensional computer graphical:
Comparatively speaking, utilizing computer model to produce graph image is not the most difficult thing.If there being sufficiently exact model, having again time enough, we just can generate the exact image of various objects under different illumination conditions, but here it is crucial that in real time.Such as in flight simulation system, the refreshing of image is the most important, and the requirement to picture quality is the highest simultaneously, adds extremely complex virtual environment, and problem just becomes extremely difficult.
Display:
The universal time that people looks around, owing to the position of two eyes is different, the image obtained is slightly different, and these images merge in brain, be the formation of one about the overall scene of world around, this scene includes the information of distance.Certainly, range information can also be obtained by additive method, such as the comparison etc. of the distance of eyes focal length, article size.
In VR system, binocular stereo vision has played great role.The different images that two eyes of user are seen produces respectively, and display is on different display.Some systems use individual monitor, but after user brings special glasses, eyes can only see odd-numbered frame image, and another eyes can only see even frame image, and difference i.e. parallax between odd, even frame just create third dimension.
The tracking of user's (head, eye): in man-made environment, each object has a position and attitude relative to the coordinate system of system, and user is also such.The scene that user sees is that the direction of the position by user and head (eye) determines.
Follow the tracks of the virtual reality headgear of head movement: in traditional computer graphics techniques, the change of visual field is realized by mouse or keyboard, the visual system of user and motion perception system are to separate, and utilize head tracking to change the visual angle of image, just can connect between visual system and the motion perception system of user, feel more true to nature.Another advantage is, user removes epistemic context not only by binocular stereo vision, and can remove environment of observation by the motion of head.
User and computer mutual in, keyboard and mouse are the most the most frequently used instruments, but for three dimensions, they all unsuitable for.In three dimensions because there is six-freedom degree, we are difficult to find out and compare way intuitively the plane motion of mouse is mapped to three-dimensional arbitrary motion.Now, some equipment have been had can to provide six-freedom degree, such as 3Space digitizer and SpaceBall Spatial Sphere etc..The equipment of other Performance comparision excellence is data glove and data suit.
People can judge the direction of sound source well.In the horizontal direction, we determine the direction of sound by the phase contrast of sound and the difference of intensity, because sound arrives the time of two ears or apart from different.The common stereophonic effect auris dextra that keeps left hears that the alternative sounds recorded at diverse location realizes, so having a kind of sense of direction.In actual life, when head rotation, the direction of the sound heard will change.But at present in VR system, the direction of sound is unrelated with the motion of user's head.
Sensory feedback:
In a VR system, user is it can be seen that a virtual cup.You can try to catch it, but your hands the most really contacts the sensation of cup, and are likely to travel through " surface " of virtual cup, and this is impossible in actual life.The usual means solving this problem is to install some contacts that can vibrate to simulate sense of touch at glove interior layer.
Voice:
In VR system, the input and output of voice are the most critically important.This just requires that virtual environment can understand the language of people, and can be with people's real-time, interactive.And it is extremely difficult for allowing the voice of computer identification people, because voice signal and natural language signal have its " polygons " and complexity.Such as, continuous speech the most significantly pauses between word and word, same word, the pronunciation of same word are affected by front and back's word, word, and not only different people says that same word can be different, it is simply that same people pronunciation also can be affected by psychological, physiology and environment and different.
The natural language making employment has two problems at present as computer input, is first efficiency, and for ease of computer understanding, the voice of input may quite be tremnbled.Next to that correctness problem, the method for computer understanding voice is contrast coupling, and the intelligence of nobody.
Utility model content
Goal of the invention of the present utility model is to provide a kind of display device, it particularly relates to a kind of display device based on virtual reality glasses.
The technical scheme that the above-mentioned technical problem of this utility model solution is taked is as follows:
A kind of display device based on virtual reality glasses, a microgap thin layer it is provided with again on polaroid in LCDs, this microgap thin layer is spaced by the thin web of multiple strips and forms, this thin web is 1/2nd wavelength plates, this thin web width and interval match with the pixel size of liquid crystal, so that it is the most orthogonal by the polarized light of thin web, finally make the even rows display left eye figure of LCDs, odd-line pixels display eye image, right and left eyes watch different images respectively to obtain perspective view.
