On January 31, 2022, Toppan Printing and the National Institute of Information and Communications Technology (NICT) announced that they had successfully completed a demonstration experiment to display photorealistic 3D images on a transparent AR (augmented reality) display.

By projecting full-color images onto a single holographic film using approximately 30 small projectors, 3D images can be displayed within a diagonal of 350 mm, horizontal viewing angle of 60 degrees, and vertical viewing angle of 10 degrees.
The “Light Stage” introduced by Toppan Printing in December 2020 is a device developed by the University of Southern California that enables highly accurate human body measurement. In the demonstration experiment, high-definition facial data, including skin texture, was measured on the light stage, and by reproducing the measured data on a transparent AR display system, we succeeded in displaying photorealistic 3D images.

Pursue the possibility of new communication by providing 3D content. For example, in the entertainment field, we will develop digital twins and virtual characters, and in the medical field, we will develop surgical training and surgery support using 3D images of the human body.
