He saw the water glass on the table and reached out to hold it.

When the bionic hand comes into contact with the water cup, a series of information such as the touch, temperature, and pressure of the palm's grip are immediately transmitted back.

It's like using your own native arm.

This wonderful feeling made Wang Dali instantly ecstatic.

He closed his eyes, picked up the water glass, and gently swung it left and right in the air, feeling the sloshing of the liquid inside.

Although he no longer relies on vision to adjust his movements, the sense of movement returned by the bionic hand can still tell his brain in real time what kind of movement his arm is in.

He could clearly feel the movements of his arms.

Whether it is shaking from side to side, the collision between the liquid inside and the cup wall, or the slight collision between the bottom of the cup and the table when the water cup is placed on the table, information about the surrounding environment is clearly conveyed to him.

This sense of movement and feedback are the most critical part of making movements natural and feelings real.

Wang Dali opened his eyes again and gained a new understanding of everything in front of him.

At this time, Chen Yiqing came over with a box and opened it in front of Wang Dali.

There is a pile of black building blocks in the box, there are about thirty pieces, each one looks exactly the same, and there is no difference in appearance.

He looked at Wang Dali with interest, blinked and smiled.

"These are building blocks used for tactile feedback testing. Each piece has a different softness and hardness."

"You need to use the bionic hand to sort them according to their touch, from soft to hard, and arrange them in different degrees."

"Let's see how far we can go?"

"This is not easy, look at me!" Wang Dali looked at the building blocks in the box. Although he said this, his expression became serious.

He knows that this is a test and a challenge.

The bionic hand reached into the box and gently picked up a building block.

Almost instantly, Wang Dali felt as if he was holding a piece of metal, which was extremely hard.

He quickly took out the building block and placed it on the table.

Then, he reached into the box again and pinched a building block.

This time, what Wang Dali felt was a kind of softness like plasticine, which seemed to deform if he applied a little force.

He put it on the table without hesitation, keeping a long distance away from the hard block.

Immediately afterwards, he took out building blocks one after another.

Every time he took it out, Wang Dali immediately felt the softness and hardness of the building blocks.

Then place them on the table in order from soft to hard.

There were several building blocks that he felt were very similar in softness, and he hesitated for a few seconds, pinching them again and again before making a decision.

Later, he didn't even need to look at his arm. He only needed to fumble around in the box for a while to find a building block, feel its hardness, and place it in the correct position on the table.

In the end, it took less than five minutes in total.

He finally took out all the building blocks from the box and placed them on the table one by one.

Bang bang bang!

A burst of warm applause broke out.

Everyone couldn't help but applaud the wonderful performance of the bionic hand.

Amidst the applause, Chen Yiqing smiled lightly, grabbed all the blocks with both hands, and threw them all into the box.

He shook the box to mix the bricks together, then pushed it over again.

"Now, try to pick out the bricks with a specific softness and hardness from this pile."

"1 is the softest, 10 is the hardest, pick out those blocks with a softness around 5 and 6."

"Do it again."

"..." Wang Dali looked at him speechlessly, and suddenly wanted to punch that elegant smiling face.

At the same time, a feeling of being tired and unloved came over my heart.

He suddenly understood how those mice in the laboratory felt.

Sure enough, it was very interesting and exciting to design a series of test tasks.

But if you are doing these tests yourself...

He would rather die than want to be a guinea pig anymore.

Let those with disabilities experience the joy of having arms again.

They are definitely willing to be guinea pigs and complete various arm functional task tests.

Wang Dali's mind turned and he made a decision instantly.

"Oops, I seem to have feelings in my hands. The anesthetic may have worn off."

He said with a sad face: "Although I am willing to try, this opportunity can only be given to Aaron."

The medical student scratched his head and was a little confused: "It shouldn't be, but it's okay. Maybe your body is not sensitive to this anesthetic. I will ensure the amount next time."

Wang Dali shook his head quickly: "I decided to stick to my original intention as a scientific researcher. I will not participate in the game myself and let patients experience the joy brought by the new product."

In this way, Wang Dali successfully escaped the fate of a white mouse, became a happy onlooker, and recorded the experimental data.
Chapter completed!
