Looking at the people in the audience, Wu Hao said with a smile: "Actually, I still have a lot to say about this pair of gloves. It feels like we suddenly have a treasure or a fun toy, especially for friends and family." Sharing, that is, sharing this happiness, is not a kind of showing off.”
Hehehe, everyone in the audience chuckled when they heard this.
Wu Hao continued: "However, due to time constraints, I can only introduce it here. This pair of smart sensing gloves also has many interesting and experiential functions. It is up to everyone to come down and understand and experience it personally. Believe me, You’re going to love it.”
Wu Hao smiled at everyone in the audience, then changed a PPT and said: "Generally speaking, as an ordinary VR user, he has such a high-performance VR glasses (including the host) and such a pair of dexterous smart sensing gloves. It is enough to handle more than 60% of the usage scenarios in the entire virtual world. It can be said that there is basically no problem in daily operations.
However, in the eyes of many people who pursue the ultimate, this is not enough. We humans move not only our hands, but also our feet and our entire body. These may not be used in general operations, but they can be used in some special occasions.
For example, when running, you need a special device to record the precise data of your body while running.
For example, the distance between your left and right feet from the ground, the distance between steps, and running posture, etc., all require special sensors to record.
For another example, if you want to play a dancing game in the virtual world, then you need a VR motion capture tracker. Use it to capture your body dynamics and transmit these motion data to the virtual characters in the VR virtual scene in real time.
Simply put, it is a motion capture device that synchronously transmits your real-person movements to the virtual world.
I believe that viewers who have watched "The Player" also dream of having such a set of clothes worn by the protagonist in the movie. "
"Yes!" Many fans in the audience responded excitedly.
After receiving the response, Wu Hao laughed and said: "In fact, if it was just about transmitting our body movements, this technology would have already been available and it would be very mature.
There are many types of human motion capture technologies currently on the market, generally divided into three major types.
The first category is to use optical positioning technology to capture our human body movements. This is also the earliest and most widely used motion capture technology.
The principle of this technology is actually to use laser, infrared ray, or visible light to position numerous three-dimensional coordinates on the sports stage, thereby capturing human body movements.
At present, it has been widely used in the production of film, television, animation and games, and is used to bundle virtual characters in 3D software. Many of the film and television works, animations and even the action expressions of characters in games we see are produced using this set of technologies.
The second category is light and shadow image recognition and capture technology. To put it simply, it uses a 3D camera to record human body movements, and then uses image recognition technology to identify the movements and postures of the people in the pictures recorded by the 3D camera.
This technology is also very mature. For example, when we first participated in the Hangzhou exhibition, we used this motion image capture technology in the performance we jointly demonstrated with students from Hudong University of Technology.
Of course, this technology also has certain limitations, that is, it is not precise and delicate enough. What it captures is only the moving image of the human body. If the images of our limbs overlap, it will be more difficult to capture. Therefore, we generally use multiple 3D cameras to capture together in multiple directions to improve the accuracy of its capture and recognition calculations.
The third category is the technology used in the smart sensing gloves I showed before. Use numerous sensors all over the human body to record the movements of various parts of the body, thereby achieving accurate capture of human body movement postures. "
After saying so much in one breath, Wu Hao couldn't help but swallow his saliva. Although I don’t know if the people in the audience and those watching the live broadcast can understand it, I still need to make some professional things clear, otherwise it will be easy to encounter arrogance and refutation.
After taking a breath, he continued: "These three technologies each have their own advantages and disadvantages. Although the first technology is more widely used, this set of optical capture equipment is very expensive, and we ordinary individual users are very Unbearable.
Initially, this set of equipment cost about one million yuan. In recent years, with the continuous introduction of similar domestic equipment, the price of this type of equipment has dropped a lot, but it is still around hundreds of thousands.
Moreover, the installation and maintenance of this kind of equipment are troublesome and require professionals to complete, so it is difficult to popularize it to our mass users.
Of course, there are some excellent products of this kind on the market now, and you can choose according to your actual situation, as long as these devices can support our operating system application protocols. "
As he spoke, Wu Hao changed a PPT, and then continued: "The second one is light and shadow image recognition and capture technology. Its main equipment is this 3D somatosensory camera. The price of this 3D somatosensory capture camera is relatively cheap. Very suitable for some novices to choose to use.
We will also launch such a 3D body-sensing camera, which can not only support our body motion capture, but also capture our gestures. Its recognition rate can reach more than 80%, which is completely sufficient in general application environments.
In other words, with this 3D body-sensing camera, you do not need to buy smart sensing gloves or such complex motion capture equipment to achieve basic control and operation of virtual scenes.
As an experiencer and developer, I suggest that if you want to buy it, you can buy two at once. Then place them at an angle greater than 90 degrees to your body, so that it can recognize your body movements at a higher rate.
Of course, it cannot perform fine operations, such as subtle movements of the body, and some subtle movements of the fingers of our hands, etc. It cannot accurately recognize it. This is not because our technology is not good, but because this technology inherently has a congenital flaw, and there is currently no way to solve it. "
He stopped here, then picked up the water on the side and took a sip to moisten his burning throat, and then stood in the middle again.
There were so many people at the scene, and the weather was really hot. Especially when the high-power spotlights were shining in front of the stage, it was very uncomfortable. It was like walking in a hot desert.
When everyone present saw this, they also gave him encouraging applause. The content at today's press conference was full of practical information, so he needed to keep talking. This was a test for Wu Hao, and everyone in the audience naturally saw it.
Thank you, Wu Hao squeezed out a smile and said: "As for the third technology that uses sensors to capture human posture and movements, this is also the technical product we are introducing to you today. Its principle is the same as the technology of smart sensing gloves we previously introduced. , but we applied it to the capture of full-body movements.
This is not a simple copy. In fact, there are many things to consider, such as far more sensors than smart sensing gloves, as well as technical problems such as the order and combination of these sensors and human body posture correction. "
