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影像装置系统，使屏幕颠簸地移动，以连续的、有机的、动态的方式作用于投影影像和观众。屏风是针对日本传统的固定装置和家具“屏风”的形状而设计的。由于屏风可以独立使用，并且具有模块化的分接功能。凹凸屏上图像内容的研究（1）有效投影CG图像的生成。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)2.通过使用双凸透镜生成双目视觉CG图像，根据观众的移动和位置变化将图像转换为折叠屏幕的视觉效果实验。振动筛的运行研究（1）直线运动控制振动筛振动的基本运行实验。(2)用小气缸矩阵驱动屏幕颠簸的系统安装。作为研究成果展示的展览最初，凹凸屏系统被ACM-SIGGRAPH 2006的美术馆部分接受，并在SIGGRAPH 2006，SIGGRAPH 2007，SIGGRAPH 2008和ASIAGRAPH 2008等众多展览中报道了研究成果。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致动系统分开。这一成果不仅可以应用于媒体艺术和内容产业，还可以为日本的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.
