Military Technology

Back at the press conference, Wu Hao changed a PPT, and the screen showed a schematic diagram of the decomposition of this pair of smart sensor gloves.

Glancing at the teleprompter in front of the stage, he collected his thoughts, and continued: "Actually, this pair of smart sensor gloves is already perfect.

Owning it means that 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.

But we think this is not enough. The smart gloves can only transmit our gestures in one direction, but they cannot feed back the data information in the virtual world to the gloves for our hands to sense.

Simply put, that is, we use our hands to grab an item. When we grab it, we can also feel its presence.

As for our pair of smart sensing gloves, we can intelligently experience our movements of grabbing virtual objects, but we cannot feel the existence of this virtual object.

It seems that we have grasped the object, but it is only a virtual object in the virtual world. But what we grasp in the real world is air, so we can't sense anything, which affects our immersive experience.

Therefore, we are thinking, is there such a technology that can act on our hands through our smart sensing gloves when we grab, pinch, and touch virtual objects? "

When such a question was raised, Wu Hao then replied: "This idea is great, but it is very difficult to realize such a technology. To develop this technology, we must first understand what is the sense of touch. .

The sense of touch refers to the sensation produced by the contact of tactile receptors on the skin with mechanical stimuli, which is caused by the action of pressure and traction on the tactile receptors.

When the external force acting as a suitable stimulus continues to act or is strong and reaches a relatively deep level, it is called a pressure sensation. If a clear distinction is made by the recording of nerve discharges, the continuous stimulation of nerve discharges is called pressure sensation, while a small amount of non-sustained discharge is called tactile sensation. The adaptation of pressure discharge is slow, while the adaptation of touch is fast.

Contact points are scattered on the surface of our human skin. The size of the contacts is not the same, and the distribution is irregular. Generally speaking, the finger pulps of our hands are the most, followed by the head, the back and the lower legs are the least, so the tactile sensation of the finger pulp of the hand most sensitive.

In other words, our hands have a very sensitive tactile system in humans. And how to use technology to simulate the different tactile sensations produced by our hands touching various materials is also a problem that we will continue to think about and solve now and in the future.

However, after some in-depth research on the tactile system,

We also found an initial 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 sense of touch and pinch when our hands grab objects.

We added a kind of bubble array pressurized material that we developed in-house, which is a bit like the bubble protection film in our packaging box.

The difference is that we inject a non-toxic and harmless special gas into each bubble, and control the state of the bubble through electronics. Normally, the bubble is in a shrinking state, but after electronic control, the bubble will expand rapidly. From the initial softness to firmness, 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 contraction, softness, hardness, and hardness. In addition, cluster control can be used to control the softness and hardness of the bubbles at different positions, thereby simulating the different pressure and tactile sensations felt by various parts of the hand when a person grasps different objects.

It is also because this array of bubble groups can simulate the degree of opening and closing of our hands when we take objects of different sizes, thereby further increasing its sense of reality.

To put it simply, the degree of opening and closing of our hands is different when we pick up a water glass and a pen, and this set of bubble pressurization simulation system can simulate this pinching feeling out of thin air.

How about it, is it great? "Wu Hao asked the audience.

Crack, clap, clap... In addition to some applause, what responded to him was warm applause. I can see the excited faces of many people in the audience, especially those fans and company employees.

Wu Hao pressed his hands with a smile on his face, motioning for everyone to be quiet, and then continued: "Actually, this is just the first step, that is, the sense of control.

The most difficult thing to simulate here is the feeling of touching. When we touch objects of different materials, the feeling of our hands is different. How to simulate this in the world is also a major technical problem.

Frankly speaking, we don't have a perfect solution for this yet. At present, we can only use this set of bubble pressurization simulation system to simply simulate some objects, which can give you a preliminary touch and touch.

Makes you feel like you're touching an object rather than a mass of air. As for its realism, especially simulating the touch of different material objects, we have to continue to find better solutions.

Sorry, our technical ability is still very limited, let everyone down. "

Facing Wu Hao's slightly apologetic words of apology, the audience in the audience cheered up one after another, and then these noisy comforting voices finally turned into a burst of warmer applause.

And on the Internet, countless netizens were moved by his words.

"Damn it, what are you doing for such a sensational press conference? Bad reviews."

"No, I'm going to cry, this bastard Wu Hao is too good at fooling people."

"I am moved, Wu Hao's words are very frank, I love them, I will definitely buy a pair of these gloves after they are released."

"Let's not talk about them, this technology is a big technical problem in the world. It's not their fault. At least they are working on the technology in a down-to-earth manner."

"Either way, this smart sensory glove is already amazing. Being able to feel the presence of virtual objects is really cool."

"Upstairs, what you said made me miss it."

"You group of silver talents, why do I want so much?"

"Brother, you are not the only one I want. Don't talk about it. I'll go to the official website to see when I can make an appointment."

"Haha, you are not as smart as I am. 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 it. But it's late at night, I'm afraid it's already closed there."

"No, today is Haoyu Technology's press conference, these brand experience stores must be packed with fans to watch the live broadcast of the press conference together."

"Then don't go, you won't experience it even if you go."

"If you can't experience it, you can take a closer look. I can't wait."

"Go together, go together, I'm already in the car."

"+1!"
