was fortunate to receive an invitation from Acer . I participated in the Beijing station of the Acer naked eye 3D series city tour. Before going, my understanding of naked eye 3D technology was still at the stage of naked eye 3D large screen. In my impression, naked-eye 3D is more of a follow-up product of 3D technology after the rise of cinemas, and gimmicks outweigh practicality. But after experiencing Acer's naked eye 3D technology, I have a new understanding of naked eye 3D.
Let’s talk about the conclusion first: It’s too much beyond expectations! Acer's naked eye 3D technology and product completion and usability are very high. I personally think that the market potential is huge.
01 "You even want to grab it with your hands"
provides 4 experience machines on site, including 1 laptop, the model is ConceptD 7 SpatialLabs super-sensing space naked eye 3D version, 3 portable monitors, and the model is SpatialLabs View/View Pro super-sensing space naked eye 3D version series. The naked-eye 3D experiences of the two are almost the same, and the actual experience mentioned later will not be distinguished.
First of all, Acer's naked eye 3D effect is very realistic, as if the world in the screen is floating on the screen, especially for pictures with obvious depth, the three-dimensional effect is very strong. Friends who experienced the scene even reached out to grab the picture they saw, but the result was obvious and they caught a short time.
Secondly, even if you move back and forth while watching, of course the movement distance should not be too large. The 3D effect you see is still the same as before, and there will be no ghosting or false appearance.
The viewing effect of Acer naked eye 3D is very close to that of AR glasses , which is better than the effect of 3D cinema (or maybe I haven't seen 3D movies with excellent results), but you don't need to wear any hardware devices.
02 How exactly does it do it?
achieves such a brilliant naked-eye 3D effect, and is supported by a complex set of algorithms and hardware. I don't know much about the algorithm, and the experts in Acer just mentioned it simply. Let’s focus on some of the techniques mentioned on the spot. It should be noted that the following description will contain personal understanding and some of the content may be incorrect.
Before this, you can simply think about how we have stereoscopic vision. When we look at an object, the left and right eyes can obtain two images. These two images have parallax , and the brain then compares the information of the two images to obtain distance, concave and convex information.
So if you want to "fake" the 3D effect, you need to provide a suitable parallax image based on the distance between the human eye and the screen, which can be split into 5 points. First, we need to know the distance between the human eye and the screen, and this distance is not fixed and needs to be tracked; second, we need the depth of field information of each part of the image; third, we need an algorithm to simulate the depth of field information into a parallax image; fourth, we need a special screen that can display parallax images; fifth, the entire process requires a large amount of calculations, and it must have good computing power support.
Due to parallax images, the camera and mobile phone cannot capture naked eyes 3D effects.
Let’s take a look at how Acer naked eye 3D is done.
There are two image sensors above the screen of SpatialLabs View Pro Super Sensitive Space Nude Eye 3D Edition (Naked Eye 3D Portable Display for Live Experience). It can recognize and track the user's head and eyes, and provide real-time feedback on the user's position information, solving the problem of distance between the human eye and the screen. Of course, since two image sensors can only track one person's face and eyes, Acer's naked eye 3D is currently only suitable for one person.
3D content includes 3D images and 3D models. The former itself provides two images with parallax, and the latter contains rich depth of field information. What to do when facing 2D content? Acer's naked-eye 3D approach is to use self-developed AI algorithms to convert 2D content into 3D content, which is equivalent to automatically calculating the depth of field information in the image through an algorithm. There is nothing to say about the algorithm for
to simulate parallax images, this should be the core of the system.
In addition, Acer's naked eye 3D screen is specially made, with a layer of optical lens on the surface. Personally, I guess that the image refracted by the original image + the optical lens is superimposed on one piece, which is equivalent to the image obtained by each of the two eyes. The refractive index of the optical lens can be controlled to simulate images obtained by the eyes at different distances.
Finally, among the products demonstrated on the spot, the host configurations connected to the three portable monitors are unknown. The ConceptD 7 SpatialLabs super-sensing space naked eye 3D version of the independent graphics card is Intel i7+RTX 3080. It seems that the requirements for computing power are really not low.
03 What is its value?
Personally, I think that the biggest advantage of Acer naked eye 3D is not only the excellent naked eye 3D effect, but also the need for any hardware equipment assistance. It reduces the user's learning and operation costs to a very low level, so low that you only need to be in front of the screen. This extremely outstanding ease of use determines that it is more acceptable in the industry.
It can be foreseen that in the future, the demand for such technologies will increase and increase in the future. Acer naked eye 3D achieves what you see and what you get, which can significantly improve efficiency. And companies are very willing to pay for improving efficiency.
Acer naked eye 3D is suitable for industries that use image as important output, such as three-dimensional design, medical field, retail exhibition field, and education field. Personally, I believe that the first field where Acer naked eye 3D was widely adopted is most likely education and training, which is also the first field where consumers can get in touch with Acer naked eye 3D.
Education and training market has always had an urgent need for innovative educational tools. Acer naked eye 3D has two obvious benefits, one is that it can bring better training results, and the other is that it can attract more potential customers. Moreover, the education and training market is large enough, and the economic benefits brought by Acer naked-eye 3D can be reflected faster.
It is precisely because I see its possibility in the education and training market that I think it has huge market potential.
Some curious friends ask about the price of ConceptD 7 SpatialLabs super-sensory space naked eye 3D version. When I heard that it exceeded 50,000 (not the final retail price), my heart trembled. The technology is very good. When it is currently in the stage of technological innovation, the cost is relatively high and suitable for commercial use, but it is still a while before flying into ordinary people's homes. But my personal judgment is that the independent naked-eye 3D display is the protagonist of this year's new product, and the price should be around 10,000 yuan, so let's wait and see.
