VR and AI costs
The costs of VR and AI vary from project to project, and specific figures cannot be given. The following are some factors that can affect the cost of VR and AI:
-In terms of VR, hardware equipment costs, software development costs, content production costs, etc. need to be considered.
-In terms of AI, computing power costs, data collection and processing costs, algorithm development costs, etc. need to be considered.
Generally speaking, with the advancement of technology and intensified market competition, the cost of VR and AI is gradually decreasing. At the same time, the popularity of open source software and cloud services has also provided more flexible and economical solutions for VR and AI applications. For enterprises or individuals, they need to comprehensively consider their needs, budget and actual capabilities to choose the most suitable VR or AI solution.
VR glasses range from tens to hundreds of dollars, and they are all amplifiers. What’s the difference?
Surface differences: appearance and comfort
DIY VR glasses Although the cost is low, they have a very embarrassing problem: the appearance is too low, and if the material is rough and it comes into contact with the face, it will scratch the face. When using it, you need to hold the two sides with both hands and stick it tightly to the eyes, which takes a long time. Being long is also a burden on the arms. No way, who makes our pictures cheap?
The biggest advantage of branded VR glasses is that they usually have a "good selling appearance", and the part in contact with the eye sockets will be covered with a layer of soft sponge pads , and is equipped with a head-mounted attachment that can be easily fixed on the head, freeing both hands during use. In short, pleasing to the eye and comfortable to wear are the external killer features of branded VR glasses.
Differences in visual field: lenses, interpupillary distance, object distance and field of view
Branded VR glasses still have a bit of "technical content", which is mainly reflected in lenses, interpupillary distance , object distance (focal length) and field of view angle, these three points will determine whether the "view" during the VR experience is clear.
To put it simply, the material of the lens will affect the clarity of the picture. The significance of aspherical surface is to reduce distortion; the larger the field of view, the wider the range that the binoculars can see, and the sense of immersion will be reduced. The stronger; the significance of adjusting the interpupillary distance is mainly to alleviate visual fatigue; and the so-called object distance adjustment is to take care of myopic users who wear glasses. After taking off the glasses, you can also see a clear picture by adjusting the object distance.
As can be seen from Table 1, although the cost of DIY VR glasses is low, it is meaningless for users with severe myopia (cannot see clearly). Most branded VR glasses support object distance adjustment of 600° or higher, which is sufficient for the vast majority of myopic users.
Unfortunately, when branded VR glasses adjust the object distance, both eyes change at the same time, which is a bit of a tragedy for my "myopic" eyes like the author, whose left eye is 300° and the right eye is 450°. Currently, there are only a few VR glasses such as PlayGlass that support the adjustment of object distance for both eyes. I hope more brands will follow suit in the future.
After seeing this, I believe everyone has understood the reason why brand VR is expensive. They have optimized processing for wearing comfort and myopia adjustment. However, these improvements can be achieved with only minor modifications to the physical structure and at almost no cost. So, what is the reason why brands of VR glasses are divided into three, six or nine?
Differences in experience: interaction and APP
The biggest flaw of DIY VR glasses is Interactive features are missing. For example, we need to run the VR APP on the mobile phone in advance, or enter the VR video playback interface, and then put the mobile phone into the glasses to watch. When the video ends or when you want to perform other operations (such as a sudden phone call), you need to take out the phone, switch to the next video, and then put the phone into the glasses without any trouble. Branded VR glasses naturally do not have this cumbersome operating logic, and their solution is to add interactive functions. Therefore, the implementation principle of interactive functions has become the basis for increasing the prices of products of different brands.
Today, the interaction modes of branded VR glasses are mainly divided into two categories. One is products represented by Baofeng Magic Mirror 4, Lingjing Xiaobai 1S, and Dapeng Kankan, which do not have any internal circuits and Electronic components are still "purely optical devices". Their interaction method is derived from Bluetooth controllers and APPs, allowing visual content to provide corresponding feedback based on the user's head movement, and providing real-time manipulation methods.
If there are no Bluetooth controllers, then they will have no difference in experience from DIYVR, they will be just a set of simple "head-mounted 3D players".
The second category is VR glasses represented by Pico1 and GearVR3. Their interaction does not require the use of other peripherals. Instead, the right side of the glasses is equipped with a touchpad, volume keys and Return button, we can use them to operate in VRAPP (you need to connect the phone to Pico1 via Bluetooth in advance). Therefore, most of these VR glasses are equipped with lithium batteries, control circuits and other electronic components. The sound output is also through the headphone jack of the VR glasses, and the price is naturally more expensive than "pure optical equipment".
.
Taken together, the cost of the first type of VR glasses is relatively lower, and the experience of using a controller to control VR games is more convenient. Although the second type of VR glasses has a slightly higher technical content, when encountering VR games, they often need to be equipped with a Bluetooth controller to play.
As for VR APP, each brand of VR glasses mostly has its own APP, which contains videos, pictures, games and many other resources. Some APPs are also compatible with other brands of VR glasses (such as PicoVR) and Bluetooth controllers. In addition, the resources of various VR APPs can be downloaded and support each other, so if you feel that a certain APP has few resources, you can consider changing APP to try to solve the problem.
Virtual reality
Technology is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment. It is a multi-source information fusion, interactive System simulation of a unique three-dimensional dynamic scene and entity behavior immerses the user in the environment.
Introduction
Virtual reality technology is an important direction of simulation technology. It is a collection of simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensing technology, network technology and other technologies. , is a challenging cross-tech frontier discipline and research field. Virtual reality technology (VR) mainly includes aspects such as simulated environment, perception, natural skills and sensing equipment. The simulation environment is a real-time dynamic three-dimensional realistic image generated by a computer. Perception means that ideal VR should have the perception that all people have. In addition to the visual perception generated by computer graphics technology, there are also perceptions such as hearing, touch, force, movement, and even smell and taste, which are also called multi-sensory. Natural skills refer to a person's head rotation, eyes, gestures, or other human actions. The computer processes data that is adapted to the participant's actions, responds to the user's input in real time, and feeds back to the user's facial features respectively. . Sensing equipment refers to three-dimensional interactive equipment.
Development History
The evolution and development history of virtual reality technology can be roughly divided into four stages: the simulation of sound, shape and dynamics is the first stage that contains the idea of ??virtual reality (before 1963) ; The germination of virtual reality is the second stage (1963-1972); the emergence of the concept and theory of virtual reality is the third stage (1973-1989); the further improvement and application of virtual reality theory is the fourth stage (1990-2004) .
ai smart glasses cost structure
ai smart glasses are a device that virtually displays or plays multimedia content on glasses. AI smart glasses in the prior art generally include a frame, a display lens symmetrically arranged in the frame, and two temples. The signal transmission method between the electronic unit on the frame and the electronic unit on the temples is wired transmission, mainly The electrical connection between the electronic unit on the frame and the electronic unit on the temple is achieved by passing a cable through the connecting shaft. This structure can easily cause the wired cable to bend when the glasses are folded, which can lead to poor contact and reduced reliability over a long period of time.
3. In addition, the control of the app in smart glasses in the existing technology is generally controlled by a controller, and the controller and smart glasses cannot form an integrated structure. In view of this, it is necessary to improve the AI ??smart glasses in the existing technology.
The function of VR glasses is to guide users to have a feeling of being in a virtual environment.
VR glasses are VR headsets, virtual reality head-mounted display devices. Since there was no concept of head-mounted display in the early days, unprofessional names such as VR glasses, VR goggles, and VR helmets were given based on the appearance.
VR headsets use head-mounted display devices to close people's vision and hearing from the outside world, guiding users to have a feeling of being in a virtual environment. The display principle is that the left and right eye screens display images for the left and right eyes respectively. After the human eye obtains this differential information, it creates a three-dimensional sense in the mind.
Extended information:
The principle of VR glasses is similar to that of human eyes. The two lenses are equivalent to eyes, but they are far less intelligent than human eyes. In addition, VR glasses generally split the screen and cut the content in half, and achieve superimposed imaging through the lenses.
At this time, the center of the pupil, the center of the lens, and the center of the screen are often not in a straight line, resulting in poor visual effects, unclearness, deformation, and many other problems.
The ideal state is that the center of the pupil of the human eye, the center of the lens, and the center of the screen should be in a straight line. In this case, you need to adjust the interpupillary distance of the lens to make it coincide with the interpupillary distance of the human eye, and then use The software adjusts the center of the screen to ensure three points and one line.
To obtain the best visual effect. Some domestic devices are adjusted physically, and some are adjusted through software. For example, the interpupillary distance of the Baofeng Magic Mirror needs to be adjusted through the knob above, while the SVR Glass requires software to adjust the interpupillary distance.
