Back at 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 collected 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 is when we use our hands to grab an object. We can feel its presence when we grab it.
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 captured the object, but it is only a virtual object in the virtual world. But what we capture in the real world is air, so we can’t sense anything, which greatly affects our immersive experience.
Therefore, we are thinking, is there such a technology that when we grab, hold, and stroke virtual objects, this tactile feeling can be applied to our hands through our smart sensing gloves? "
When asked such a question, Wu Hao then answered himself: "This idea is great, but it is very difficult to realize such a technology. If we want to develop this technology, we must first understand what touch is." .
Touch refers to the sensation produced 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, while the non-sustained small amount of discharges is called touch sensation. Pressure discharge adapts slowly and tactile discharge adapts quickly.
There are contact points scattered on the surface of our human skin. The size of the contact points is different and the distribution is irregular. Generally, 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. Most sensitive.
In other words, our hands have a very sensitive tactile system in humans. How to use technology to simulate the different tactile sensations produced by our hands touching various materials is also a problem that we must continue to think about and solve now and in the future.
However, after some 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 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 glove, which is a bit like the bubble protective film in our packaging box.
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. Normally, this bubble is in a shrinking state, but after electronic control, the bubble will expand rapidly. From the initial softness to the hardness, the entire reaction time is very short, only a few tenths of a millisecond.
And through control, we can make this bubble show several states such as shrinkage, softness, hardness, hardness, etc. And the softness and hardness of the bubbles at different positions can also be controlled through cluster control, thereby simulating the different pressure tactile sensations felt by various parts of the hand when a person grasps different objects.
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 about it, great? "Wu Hao asked the audience.
Bang 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, signaling 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 area yet. 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 when it comes to simulating the touch of objects made of different materials, we still have to continue to look for better solutions.
We are 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 more enthusiastic round of applause.
On the Internet, countless netizens were moved by his words.
"Damn it, what a good press conference, why are you so sensational? Bad reviews."
"No, I'm going to cry. This bastard Wu Hao is so good at deceiving people."
"I'm touched. Wu Hao's words are very frank. 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."
"In any case, this smart sensing glove is amazing. Being able to feel the presence of virtual objects is really great."
"Upstairs, your words made me think astray."
"You guys are so talented, 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, so I'm afraid they're already closed over 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 see it up close. I can't wait."
"Go together, go together, I'm already in the car."
"+1!"
