The second generation of Yuanshen hand, with a touch feedback function.

The biggest difference between the machine and the body is that the former has no feelings.

Use the manipulator to smash the wall, and the manipulator will not feel it even if it is damaged. If you change to the physical body, it will be painful.

But often many times, when the sense of touch is not so strong, it will bring an extremely comfortable enjoyment.

For example, when you hold hands with someone of the opposite sex, you will feel a warm heartbeat in your hand.

For example, touching an object and feeling the texture of the surface of the object sliding on your hand, whether it is silky, cold, or soft.

Touch can help people recognize many things, and it is also the most important way for people to feel in addition to their visual senses.

The manipulator, of course, has no sense of touch.

Even if the machine is fake, it is still a dead thing, and it cannot help the user to feel life.

When the electrocrystalline records a large number of bioelectric signals, it has a whim, what if these signals are transmitted to the user in turn?

The bioelectric signal collected by the induction chip to the human body is digitally transformed, and then the signal is transmitted to the Yuanshen hand, so that the Yuanshen hand can work in the way the user wants.

So theoretically, it is technically feasible to reverse this process and let the Yuan Shen hand generate an electrical signal and then transmit it to the human body.

In the past few years, TV shopping has been popular for a while, and electronic acupuncture and massage devices have similar functions.

It's just that this kind of device, which costs less than 100 yuan, can only emit a single biocurrent, so that the muscles can beat uncontrollably and feel the tingling sensation under the stimulation of the current. The distance between simulating the touch is still the technical gap from the earth to the moon.

Jiang Shuya took a black object the size of a cigarette case, and the reverse side of this object had a gel coating that could be attached to the skin.

"It's a tactile collector. Jiang Shuya introduced: "After a large amount of data analysis, Giant Beast Industry found that no one person's neural signals are the same. These neural signals can be used to distinguish users like fingerprints. ”

"Men are not the same as women, and twenty and thirty are not the same. ”

"Even different moods can affect the frequency of nerve signals. ”

"So what?" Wang Yanyu took the collector with his right hand and observed curiously, and he found that through the gel layer on the collector, he could see that there was a golden complex circuit diagram similar to an integrated circuit inside.

"So at the moment, the Genshin hand can't perfectly feedback the touch, it can't give back the deeper sensation such as itchy, wet, cold, smooth, etc. ”

"At the moment, it can only respond to the feeling of weight, heat, pressure and pain. ”

"It's enough. These feelings have far exceeded Wang Yanyu's surprise.

As instructed, the haptic collector is best attached to the other hand. In this way, the captured signal can simulate the user's hand touch as much as possible. If you don't have your hands, you can stick them on your feet or your face.

Wang Yanyu chose to stick it on the back of his right hand, then started the collector and used his right hand to collect touch.

Starting from a weight of 100 grams, Wang Yanyu grabbed it with his right hand in turn, 300 grams, 500 grams, 1 kilogram, 2 kilograms, until the weight was 10 kilograms. There weren't so many weights in the laboratory, so Jiang Shuya simply took out a dozen bottles of drinks from the refrigerator to recharge.

Shake hands with Jiang Shuya.

Tap the keyboard with your right hand.

Hold a cup of hot water.

Tap each finger with the probe......

The data collection work lasted for two hours, and with the help of Jiang Shuya, Wang Yanyu collected almost all the tactile senses that he could come into contact with in his life.

These haptic data will be stored in the chip of the Genshin Hand, under the synergy of up to 17 highly sensitive sensors such as multi-dimensional force sensors, distance sensors, temperature sensors, pressure sensors, etc. The Genshin Hand can accurately determine the object it touches, and select the most suitable touch from the database, which is directly fed back to the nerves at the end of the user's residual limb.

When the control watch sent a prompt for the completion of data analysis, Wang Yanyu's preliminary preparations were also completed.

He stood up, took a deep breath, and put his right hand in his pocket.

Usually, when Wang Yanyu goes out, he puts his left hand in his pocket.

Putting the "left hand" in your pocket will of course greatly reduce the curiosity rate of the surrounding crowd compared to an empty left hand. So Wang Yanyu now chooses clothes, only clothes with loose pockets.

"The first tester of the Genshin Hand was a teenage boy in our hospital. He can now use the Yuan Shen Hand to do most of the normal hand functions except for playing Glory of Kings. Jiang Shuya saw Wang Yanyu's nervousness.

"By the way, that boy named Su Yuhang can even operate the mouse with the Yuan Shen hand. When I see him playing League of Legends, he is not affected at all. ”

"I won't let you down. Wang Yanyu turned his head and smiled affirmatively.

……

Wang Yanyu ate a staff meal at Mead Hospital before leaving.

He is now a supernumerary member of Mead Hospital, and he is given a daily allowance of 500 yuan. After a while, the subsidy will rise to 2,000 a day.

This is not the key issue, the key issue is that Wang Yanyu has become "left-handed".

Wang Yanyu usually takes the subway to travel now, and after coming out of Mead Hospital, he puts his right hand in his pants pocket and walks down the street with his left hand swinging.

It's summer, and it's easy for him to get a look of "aren't you afraid of the heat" from others.

Wang Yanyu didn't care, he would even touch his face with his left hand from time to time.

On the left hand, there is a touch that is not delicate.

On the face, you can clearly perceive the same warmth as your right hand.

What a beautiful first day, Wang Yanyu felt that he had lived a second life. From now on, his mind was cleansed and became stronger.

The left hand pulls the metro card out of his pocket and slides it over the card reader.

Following the crowd into the carriage, Wang Yanyu grabbed the handrail with his left hand.

Wang Yanyu only wore a long-sleeved shirt, but today he deliberately rolled up his left wrist.

Several young men and women around him looked at Wang Yanyu with strange eyes. Because since this guy entered the carriage, he has been staring at his left hand and smirking, and his right hand is still in his pocket all the way.

There was a fashionably dressed young guy who seemed to have spotted a blind spot.

"Hey, big brother, where did you buy this watch?" the young man raised his left black Songtuo electronic watch.

Originally, his watch was the most fashionable model this year, and many celebrities have brought it. But now compared with the piece on Wang Yanyu's wrist, it is as rustic as it is.

That piece is a black polygonal diamond, the appearance, the material, and the sense of science and technology are worth a lot at a glance.

If he also has a piece, I'm afraid he will be like this uncle, staring at his wrist from time to time and laughing.

"Haha~" Wang Yanyu smiled more heartily, he handed out his left hand and smiled: "Hello, my name is Wang Yanyu." ”

"You...... Hello. The young man stiffly handed over his hand and shook it twice, and then quickly pulled it away, not even thinking to inquire about the watch brand.

The subway stopped for one stop, and a seat was vacated next to Wang Yanyu.

He sat down and pulled his phone out of his pocket with his left hand.

Fingerprint recognition passes.

Click on the Glory of Kings.

It wasn't until Wang Yanyu entered the man-machine battle mode with a five-trumpet that he was finally willing to take out his right hand.

The right hand is intact.

Several young men and women next to him immediately booed, this uncle was really pretending.

They were still betting just now that the uncle must have lost a few fingers in his right hand, so he was reluctant to take it out.
