Bumpy Screen: Dynamic 3D folding screen display system responds emotionally as living entity

本研究的目的是开发一种新的图像装置系统，该系统可以使屏幕对投影图像和观众产生连续、有机和动态的反应。屏风针对的是日本传统的固定装置和家具“屏风”的形状。由于折叠屏可以独立存在，并且具有分割连接模块的功能。研究大纲凹凸屏上图像内容的研究(1)有效投影CG图像的生成。其中最有效的图像之一是模拟生物雕塑模型与流体之间的相互作用。(2)利用透镜生成双目视觉CG图像，根据观众的运动和位置变化变换图像的折叠屏视觉效果实验。颠簸筛的运行研究(1)直线执行器控制筛颠簸的基本操作实验。(2)采用小气缸矩阵驱动筛网颠簸系统的安装。作为研究成果展示的展览首先，坎坷屏系统被ACM-SIGGRAPH2006的画廊展区接受，并在多个展览中通过SIGGRAPH2006、SIGGRAPH2007、SIGGRAPH2008、ASIAGRAPH2008等参展单位报告研究成果。屏幕能够以视频帧率呈现3D形式。它也是交互式的，许多用户可以同时与显示器和屏幕图像进行物理交互。我们将提供高分辨率图像的图像投影系统和提供动态运动的屏幕驱动系统分开。因此，我们可以取得很大的成绩。这一成果不仅可以应用于媒体艺术和内容产业，还可以为日本传统文化赋予新的价值。

The purpose of this research is the development of the new image device system that moves bumpily the screen reacting on projected image and spectator with continuous, organic, and dynamic movement. The screen aimed at the shape of "Folding screen" that was a traditional fixture and furniture of Japan. Because the folding screen could stand alone and it had the function of the module of division and connection.Outline of research1. Research on image content on bumpy screen(1) Generation of effective projection CG image. One of most effective image is a simulation of the interaction between the biological sculpture model and the fluid.(2) Experiment concerning visual effects of folding screen to which image is transformed according to change in spectator's movement and position by generation of binocular vision CG image using lenticular lens.2. Research on operation of bumpy screen(1) Experiments on basic operation of control bumpiness of screen by linear actuator.(2) Mounting of system that drives bumpiness of screen with matrix of small air cylinder.3. Exhibition as presentation of research resultsAt first, bumpy screen system was accepted to the art gallery section of ACM-SIGGRAPH2006, and research results were reported by the participation such as SIGGRAPH2006, SIGGRAPH2007, SIGGRAPH2008 and ASIAGRAPH2008 in a lot of exhibitions.The screen is capable of presenting 3D forms in just about video frame rate. It is also interactive and a number of users can interact physically with display and screen images at the same time. We separate system of image projection that provide high-resolution image and system of screen actuation that provide dynamic motion. Therefore we can achieve great performance.This results can expect not only the application to the media art and the contents industry but also the possibilities of giving new value to the traditional culture of Japan.
