Based on efficient 3D model retrieval and 2D shape-based object recognition technology, we provide 3 major applications as an installation art system - Hand-Shadow Illusions, Interactive Gallery and 3D DDR. When technology meets entertainment, users will have a whole new experience.
This system consists of 3 components. Image capturing, image processing and 2D/3D model retrieval.
Users can play hand shadow and will have correspoinding response interactively.
Users imitate the pose of a character in some famous art work, and will have interactive response of useful information about this work.
It is a full-body version DDR. Users make their pose match the hint images dynamically shown on the screen. Users pose their body within limited time with background music playing.
This project integrates image processing, 2D/3D model retrieval, and traditional games to create new installation art.
To allow users to move their bodies or hands to create an image, and use the 2D/3D model retrieval system to evaluate their performances in an interesting game.
The system blends traditional children's games with an up-to-date 2D/3D model retrieval system.
Such a system installed in subway stations or public buildings will encourage people to relax, play, and think. The system may inspire another interaction method with the addition of multiple cameras and a retrival server as background knowledge. It could also be seen as another (not very accurate but very low cost) method for motion capture.
