Koizumi Lab
Machine-translated · View original
A lab exploring digital expression in public spaces through technologies such as aerial imaging.

AboutAbout the lab
Digital expression technologies that bring color to public spaces.
The Koizumi Lab studies information technologies that surprise and move people in public spaces such as parks and halls.
Its specialty is virtual reality, with a particular focus on how visual information is presented.
In addition to aerial images, which make images float in mid-air, the lab works on digital fabrication, augmentation of human perception, and operation using robots.
The lab shares its research results through presentations at academic conferences, as well as live demonstrations at open labs and exhibitions.
Key terms
- Aerial image
- An image that is optically made to float in mid-air for display.
- Digital fabrication
- In this lab, it refers to research on systems that project energy into the real world to manipulate the patterns and movements of objects.
- Augmentation of perception
- Methods that expand human perception and change how the real world looks.

View More ↗ResearchResearch themes
The lab studies digital expression technologies, aiming to build new media expression suited to a mature city. Its research is organized by area: aerial images, digital fabrication, augmentation of perception, and operation using robots.
Displaying images floating in mid-air
The lab studies aerial images, which optically make images float in mid-air for display. The lab does not currently work on holography.
*Illustrative imageManipulating objects by projecting energy
Just as a projector projects light to change how things look, the lab aims to manipulate objects by projecting energy into the real world. These systems can redraw the patterns on an object's surface or instruct it to move.
*Illustrative imageMethods for augmenting perception
The lab proposes methods that augment human perception and change how the real world looks. Just as Leeuwenhoek's microscope thrilled the world, the lab aims to create new ways of experiencing the world.
*Illustrative imageOperation using robots
This is an idea for operating a computer by moving a robot, as if playing with a doll.
