The smallest shooting game in the world is played with an electron beam generator

A team of researchers in Japan has created the world's smallest shooting game, which is played by less than 1 billion meter size by manipulating nanoparticles.

The project, led by Professor Takayuki Hoshino from the Graduate School of Engineering at Nagoya University in Japan, enables players to control a small triangle shooting for enemy Blobs on the display, similar to in Ataris game from 1979 Asteroid. However, this version is “nano-mixed reality”, in which the digital world combines with the real world on tiny, tiny scales.

“The system projects the game ship onto the real nanophysical area as a optical image and power field and creates an MR in which nanoparticles and digital elements interact,” said Hoshino in an explanation. “The game is a shooting game in which the player manipulates a ship and shoots balls on real nanoparticles to ward off it. This has successfully demonstrated the real-time interaction between digital data and physical nano objects. “

The enemy blobs in the video game are real nanoparticles, tiny polystyrene balls. The players can move their character, the triangle, near a joy stick – what they actually do is manipulate the scan patterns of an electron beam. These rays are used to create complex electrical fields and at the same time offer real-time images of the particles on the nano scale. The players can then “fire” the electron beam balls in the enemy nanoparticles and move them as desired.

“By scanning electron rays, which were focused at high speed on nanograsses, we managed to create dynamic patterns of electrical fields and optical images on the display surface and to control the power field that works between nanoparticles in real time,” the researchers explained in a translated YouTube video description. “With this Force field advertisement we demonstrated 'Nano Mixed Reality', which connects the information room and nanomaterial in real time and demonstrated the smallest shooting game in the world that can be freely checked in the Nano world.”

While creating tiny versions of early video games is clearly an end in itself, the researchers have created the game to demonstrate the technology that could be used to precisely manipulate materials on tiny standards.

“We could print the created objects in real time 3D and possibly revolutionize the world of 3D printing,” added Hoshino. “Or use […] Cells in living organisms and kill them. “

Hopefully new ones beforehand PAC-Man.
