Development of Human Scale Virtual Environment with a Haptic Display

创造性自由形式设计环境的实现需要集成具有高柔韧性的三维形式的输入设备、具有高级渲染功能的三维图像显示、能够生成、修改和处理自由形式的自由形式模型以及具有多模态交互功能的沉浸式虚拟环境的开发。本研究以代表研究者提出并研究的带有触觉显示的空间界面设备“SPIDAR”为基本接口，开发了多投影实现沉浸式图像空间和多PC的穹顶屏沉浸式图像显示设备，从而实现了设计环境的目的。在一个创造性的形式设计中，首先设计者所想象的形式设计形象必须在虚拟的环境中轻松自然地发展成一个三维的形式模型。因此，在虚拟环境中，必须能够通过包含触觉的多模态交互直接操作表单模型。此外，由于该操作可用于真实的比例形式模型，因此沉浸式图像显示设备必须在三维空间中显示人体比例的自由形式。我们提出并开发了这种以人为尺度的虚拟环境，从而实现了这些功能。这种设计环境有可能激发设计师的创造力，足以达到我们的研究目的。

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.
