I think the coolest six black technology is:

1. Tesla coil

Tesla coil can artificially create lightning, even up to millions of volts, when the power is relatively small, get in the body of the person is actually nothing, the person will not be electrocuted to death, to do this kind of an experiment is not cool?

3D printing technology is also very cow, like photocopying, we put a house design to the computer, 3D printer can print out an identical house. When the technology matures in the future, it will be simple to produce things, almost no need for workers, isn't it amazing?

3.AI Artificial Intelligence

Artificial Intelligence can make their own judgments, their own choices, although for the time being, it is not as flexible as the human brain, but in many ways it is more than the human brain. For example, man-machine game, the human brain is better than the computer. Also for example, driverless, although not as mature, but we can already imagine the scene of the future automatic driving. Some people may even worry about robots getting out of control and causing unbearable consequences for humans.

4. Mechanical arm on the Tiangong space station

Seeing the video of the mechanical arm working on the scene, surprised at the degree of flexibility, it is even more flexible than the human hand, can be rotated in all directions, and a lot of force, is really a big weapon on the space station.

5. Particle accelerator

Through the magnetic and electric fields to give microscopic particles to accelerate, so that it collides with other particles, so that scientists get a lot of previously unknown microscopic particles. With particle gas pedals, our knowledge of the microscopic world has changed dramatically.

6. Voyager I and Voyager II probes

They were launched in 1977, and have been in space for more than 40 years, and are still functioning normally, and have probed Jupiter, Saturn, Uranus, Neptune, and so on, as well as the satellites of the planets at close range. It is currently flying to the edge of the solar system, it is not known whether it can fly out of the solar system, there are too many unanswered questions at the edge of the solar system.

Hi, I am an entrepreneur who has been in the internet industry for over 10 years.

I think with the advancement of technology, there are infinite possibilities with holographic projection, brainwave control, and artificial intelligence around.

But I am very optimistic about the value of holographic projection, can quickly project the characters of the A scene to the B scene, can realize the communication between people, instant information interaction, such as the implementation of the doctor's surgery, the future of remote online education, equivalent to the world's best quality resources equal, in the home in China can also be on the course from the professor of Stanford University and immersed in the scene.

Then there is the application of stranger socialization scenarios similar to Stranger, which can quickly put strangers between two places through holographic projection, projected into the same space, feeling like a real person talking face to face, which can lead to unlimited kinds of social possibilities.

That's about it, I hope it helps.

Tesla car , can be driverless! Cooler! Representing the future direction of unmanned ......

Car The fuse box plus a relay, phone under an app can display speed, maintenance time, etc.

The coolest black technology is the first universe of the third dimension, also known as the main plane of the Earth highly civilized intelligent human beings have the ability to compression of the super-giant black holes into a super-high density chip, also known as an infinite energy supply; a chip with a very high density, which is also known as an infinite energy supply. Also known as infinite energy supply; a chip super advanced energy can provide energy for a number of galaxies. This universe belongs to the ninth universe Earth highly civilized intelligent human beings, after a number of millions of years of accumulation of various scientific knowledge. For example, a spaceship rely on quantum computers and intelligent core computers to store huge amounts of energy, as well as spaceships of various materials and internal structure, a variety of weapons and equipment, as well as astronauts, all personal data, and other knowledge information atomic memory chip. Even if the spaceship is destroyed, a period of time to copy the original spaceship and the number of original astronauts inside.

On the question of who is the coolest black technology, I think every Chinese must choose Huawei's products, because Huawei's products can redefine what is patriotic, what is unpatriotic, and what is selling out. Huawei's products have had an immeasurable effect on the development of human civilization.

Atomic bombs, hydrogen bombs, neutron bombs

Idea manipulation of drones, their own a certain treasure search _

There is the beginning of the technology Static to dynamic, two-dimensional to three-dimensional, gesture recognition technology to go where?

In the American Hollywood movie, often cool starring a wave of a "air projection" screen, a click on the screen in the air to open a space, door, box ...... harvest the audience after a face of confusion after the dark affirmation, then, this technology in reality how to realize? How can this technology be realized in reality?

A category of gesture recognition

In the Hollywood protagonist's footage, there are three kinds of static gestures, planar gestures, and three kinds of three-dimensional gestures, static gesture "outline" recognition, planar gestures, "changing outline + two-dimensional" recognition, and three-dimensional gestures. The static gesture "outline" recognition, flat gesture "change outline + 2D change direction" recognition, three-dimensional gesture "change outline + 3D change direction" recognition, recognition difficulty in order to rise, there is the beginning of the technology is the third three-dimensional spatial movement gesture recognition technology.

Second, the application of gesture recognition scene

From the point of view of understanding, static gesture is like a point, relative to the camera is stationary; plane gesture is like a plane sliding hand, or morphology changes, or changes in the direction of the three-dimensional gesture is like the air waving hand, the movement of the free defense, the direction of free change.

In the application scenario, VR/AR, TV, cell phones, computers ...... three-dimensional spatial motion gesture recognition is more suitable, but also the future mainstream gesture recognition program, there is a beginning technology is more focused on this area, to achieve 0.01mm recognition accuracy.

Three, gesture recognition technology program

For static gestures, through the camera to shoot two-dimensional images of objects, with big data, algorithms to analyze the characteristics of the object; for the plane gesture, in addition to shooting two-dimensional images, but also tracking, positioning, identification or speculation of the action intent; for three-dimensional gestures, in addition to the plane of the information, there are depth of field level information, the recognition difficulty is further increased.

1, static gesture recognition

This is the simplest gesture recognition, can recognize static objects, such as scissors, stone, cloth and other gestures, many short video effects, cell phone gestures automatically shoot using this technical solution.

It is a pattern matching technology that takes the 2D image information input from the camera, performs a big data comparison, and the algorithm further analyzes the image to recognize the meaning of such gestures.

This technical solution has a simple pattern, which can only be applied to the intended image recognition, with limited application scenarios to provide a basis for more complex dynamic recognition!

2, planar gesture recognition

Compared to static gesture recognition, this technical solution can recognize dynamic gestures, not only can recognize the hand shape, but also recognize some simple two-dimensional gesture movements, such as waving, palm spread, etc. However, it is also limited to a plane within the action, there is no depth of field, near and far level recognition capabilities.

In addition to image recognition, action recognition has been added, and for some switching, page flipping, and sliding ...... gesture recognition can also be realized.

3, three-dimensional gesture recognition

For three-dimensional gesture recognition, into the most complex level of gesture recognition, static gesture recognition and plane gesture recognition are the basis of three-dimensional gesture recognition, that is, to join the depth of field near and far level of three-dimensional recognition, at this time, multiple cameras for information capture, positioning, tracking can be realized.

This recognition program, the mainstream technology has a structured light (Structure Light), light time of flight (Time of Flight), multi-camera imaging (Multi-camera), and multi-camera imaging (Multi-camera) is the most inexpensive program, and the threshold of the market penetration is lower.

It is similar to the working principle of the human eye, a single eye to see the image and two eyes to see the range and angle of the different, the latter has a greater range, and has the ability to locate different directions. That is to say, multi-angle imaging to increase the ordinary camera can greatly enhance the effect, do not need any additional special equipment, hardware requirements of the lowest, completely dependent on computer vision algorithms to match the same target in the two pictures, multi-angle imaging technology, effect, cost of the integrated optimal.
