Development of Human Scale Virtual Environment with a Haptic Display

创造性自由形态设计环境的实现需要集成具有高度柔性的三维形态输入设备、具有高级渲染功能的三维图像显示器和能够生成、修改和处理自由形态的自由形态模型，以及具有多模态交互功能的沉浸式虚拟环境的开发。本研究以具代表性的研究者所提出及研究的具触觉显示的空间介面装置“SPIDAR”为基本介面，发展出多重投影以实现沉浸式影像空间，并发展出具有多台PC的半球形萤幕的沉浸式影像显示装置，以达到有目的的设计环境。设计者可视化的形式设计的图像必须容易且自然地被开发为虚拟环境中的三维形式模型。因此，必须能够在虚拟环境中通过包含触觉的多模态交互直接操作表单模型。而且，由于该操作可以用于真实的比例形状模型，所以沉浸式图像显示设备必须以三维显示人体比例的自由形状。我们提出并开发了这个人的规模的虚拟环境，并实现了这些功能。这样的设计环境能够充分发挥设计者的创造力，达到了我们的研究目的。

Realization of creative free form design environment needs integration an input device of the three-dimensional form of high pliability, the three-dimensional image display with an advanced rendering function and a free form modela that can generate, modificate and process a free form and a development of immersive virtual environment with a multimodal interaction function. This research regarded a space interface device "SPIDAR" with a haptic display that representative researcher have proposed and researched as a basic interface and developed multi-projection to realize an immersive image space and an immersive image display device with a dome screen of multi PC and as a result realized design environment at purpose.In a creative form design, at first, an image of form design that the designer visualizes has to be developed as a three-dimentional form model in virtual environment easily and naturally. For the sake, it must be possible a direct manipulation of form model by multi-modal interaction containing a haptication in virtual environment. Also, because this operation can be used to real scale form model, an immersive image display equipment must display human scale 'free form in three dimensions. We proposed and developed this human scale virtual environment and as a result realized these functions. This design environment is possible to pull out creativity of designers and enough we achieved our research purpose.
