Nagoya University Researchers Develop World’s Smallest Video Game

Nagoya University researchers have created the “world’s smallest shooting game” where targets are a billionth of a metre small.

The game operates at a nanoscale with a standard controller.

Players pilot a miniature digital ship and launch nanoscale bullets to manipulate a physical ball, measuring a few microns.

This is an advancement in “nano-mixed reality,” a technology that merges the digital and the nanoscopic worlds.

Advancing Nano-Mixed Reality Technology 

"The game is a shooting game in which the player manipulates a ship and shoots bullets at real nanoparticles to repel them.

Through this, we successfully demonstrated real-time interaction between digital data and physical nano-objects," said Professor Takayuki Hoshino, the lead developer.

How Nano Beams Enable Real-Time Manipulation of Nanoparticles

Nano-mixed reality uses high-speed electron beams to achieve real-time digital and nanoscopic physical integration.

The beams serve to generate complex, real-time electric fields and optical image patterns on the display.

These beams act like invisible hands, controlling the movement of nanoparticles.
