"RePro3D" is a full-parallax 3D display system suitable for interactive 3D applications. The approach is based on a retro-reflective projection technology in which several images from a projector array are displayed on a retro-reflective screen. When viewers look at the screen through a half mirror, they see a 3D image superimposed on the real scene without glasses.
"RePro3D" has a sensor function to recognize user input, so it can support some interactive features, such as manipulation of 3D objects. To display smooth motion parallax, the system uses a high-density array of projection lenses in a matrix on a high-luminance LCD.
The array is integrated with an LCD, a half mirror, and a retro-reflector as a screen. An infrared camera senses user input.

「RePro3D」は,高輝度LCDとレンズからなる高密度プロジェクタアレイを用いた投影型の立体ディスプレイ手法です。上下・左右の運動視差を持ったCGが空中に結像した3D映像を裸眼で観察することができます。
また,赤外カメラによって手と3D映像の接触状態を認識し,指先に装着した触覚提示装置によってキャラクタに触ったときの触感を生成することができます。
