Returning to the press conference, Wu Hao changed a PPT, and what was displayed on the screen was an exploded diagram of this pair of smart sensing gloves.
After glancing at the teleprompter on the edge of the stage, he sorted out his thoughts and continued: "In fact, up to this point, these smart sensing gloves are already perfect.
Owning it means you have a pair of dexterous real hands in the virtual world, which can help you operate many things in the virtual world. This is far more flexible, powerful, rich, and advanced than any input device in the world currently.
But we feel that this is not enough. These smart gloves can only transmit our gestures in one direction, but cannot feed back the data information in the virtual world to the gloves for our hands to sense.
To put it simply, it means that we use our hands to grab an object. When we grab it, we can also feel its existence.
As for our pair of smart sensing gloves, they can intelligently experience our movements of grabbing virtual objects, but they cannot feel the existence of this virtual object.
It seems that we have grabbed an object, but it is only a virtual object in the virtual world. But what we grab in the real world is air, so we cannot sense anything, which greatly affects our immersive experience.
Therefore, we are thinking, is there such a technology that can enable this tactile feeling to be applied to our hands through our smart sensing gloves when we grab, hold, and stroke virtual objects?”
When such a question was raised, Wu Hao then answered himself: "This is a great idea, but it is very difficult to implement such technology. If we want to develop this technology, we must first understand what touch is."
.
Touch refers to the feeling caused by the contact of skin tactile receptors with mechanical stimulation, which is caused by pressure and traction acting on the tactile receptors.
When the external force as a suitable stimulus continues to act or is strong and reaches a relatively deep level, it is called pressure sensation. If a clear distinction is made based on the recording of nerve discharges, the continuous stimulation of nerve discharges is called pressure sensation, and
A small amount of non-sustained discharge is called tactile sensation. Pressure discharge adapts slowly, while tactile sensation adapts quickly.
There are contact points scattered on the surface of our skin. The size of the contact points is different and the distribution is irregular. Generally speaking, the finger pulps of our hands are the most, followed by the head, back and calves, so the touch of the finger pulps of the hands is the smallest.
The most sensitive.
In other words, our hands have a very sensitive tactile system. How to use technology to simulate the different tactile sensations caused by our hands touching various materials is a problem we must continue to think about and solve now and in the future.
However, after in-depth research on the tactile system, we also found a preliminary solution. That is to use technology to pressurize the surface of our hands, especially the surface of the belly of the hand.
Then we use the immersive visual illusion experience brought by VR glasses to simulate the touch and grasping feeling of our hands when grabbing objects.
We have added a self-developed bubble array pressurized material to the inside of the gloves, which is a bit like the bubble protective film in our packaging boxes.
The difference is that we inject a non-toxic and harmless special gas into each bubble, and use electrons to control the state of the bubble. Usually the bubble is in a shrinking state, but after using electronic control, the bubble will quickly shrink
It expands. From the initial softness to the hardness, the entire reaction time is very short, only a few tenths of a millisecond.
Through control, we can make this bubble show several states such as shrinkage, softness, hardness, hardness, etc. And we can also use cluster control to control the softness and hardness of bubbles at different positions, thereby simulating people grabbing different objects.
When touching an object, the different pressure sensations felt in various parts of the hand.
It is also because this array bubble group can simulate the opening and closing of our hands when picking up objects of different sizes, thereby further increasing its realism.
To put it simply, the degree of opening and closing of our hands is different when we pick up a water glass and when we pick up a pen, and this bubble pressure simulation system can simulate this holding feeling out of thin air.
How is it, isn't it great?" Wu Hao asked the audience.
Bang bang bang... In addition to some cheers, the response to him was more warm applause. You can see the excitement on the faces of many people in the audience, especially the fans and company employees.
Wu Hao smiled and pressed his hand to signal everyone to quiet down, and then continued: "In fact, this is just the first step, which is the sense of control.
The most difficult thing to simulate is the feeling of touching. When we touch objects made of different materials, our hands feel different. How to simulate this is a big technical problem all over the world.
Frankly speaking, we don't have a perfect solution in this regard. At present, we can only use this bubble pressurization simulation system to simply simulate some objects, which can give you a preliminary touch of touch.
This allows you to feel that you are touching an object rather than a ball of air. As for how realistic it is, especially simulating the touch of objects made of different materials, we have to continue to find better solutions.
I'm sorry that our technical capabilities are still very limited and we have disappointed everyone."
Faced with Wu Hao's somewhat apologetic words of apology, the audience in the audience began to comfort him one after another, and then these noisy words of comfort eventually turned into a round of warm applause.
On the Internet, countless netizens were moved by his words.
"Damn it, what a good press conference, why is it so sensational? Bad reviews."
"No, I'm going to cry. This bastard Wu Hao is so good at deceiving people."
"I am touched. Wu Hao's words are very candid. I love them. I will definitely buy a pair of these gloves after they are released."
"Let alone them, this technology is a major technical problem in the world. This is not their fault. At least they are working on the technology in a down-to-earth manner."
"No matter what, this smart sensing glove is already amazing. Being able to feel the existence of virtual objects is really great."
"Upstairs, your words made me think astray."
"You guys are talented people, why do I want it so much?"
"Brother, I'm not the only one I want. I won't talk about it anymore. I'll go to the official website to see when I can make an appointment."
"Haha, you are not as smart as me. At this moment, I am already on my way to our Haoyu Technology offline official brand experience store."
"I'll go, why didn't I think of that? But it's already night, I'm afraid they've already closed down there."
"No, today is Haoyu Technology's press conference. These brand experience stores must be packed with fans watching the live broadcast of the press conference."
"Then it's better not to go. If you go, you won't be able to experience it."
"I can't experience it, but I can take a closer look. I can't wait."
"Let's go together, let's go together, I'm already in the car."
