CLEAN : 3D interactive books on display

The video introduces a system that detects pain and a 3D interactive book presentation software. This software allows users to create 3D books from 2D scans and interact with them using hand gestures. Developed in collaboration with a German library, it aims to preserve and present books in 3D. The software can also be used by bookstores and for mail order catalogs.
