A research on development of senses presentation interface and its application to virtual reality practice teaching material

本研究的目的是开发各种感觉呈现方式，因为它能提高学生对虚拟现实实践的兴趣，发展自己的想象力和创造力，制作内容。具体地说，开发了虚拟现实系统，在传统的视觉和听觉呈现的基础上，展示了嗅觉和触觉，并开发了一套可理解的实践教材。经过四年的研究，我们取得了以下成果：(1)通过将一团香味空气从某个偏远的地方输送到用户的鼻子，开发了一种无阻碍的本地化嗅觉显示，并将其应用到电影中。(2)开发了超声弹性图像可视化人体内部分割的界面，触觉界面利用触觉呈现设备显示分割的硬度分布，并试制了用于虚拟现实环境的手套式人工肌肉简单力反馈系统。(3)开发了虚拟大学校园或城镇的软件工具，可以在里面行走。(4)利用所开发的工具开发了VR实用教材，并用于课堂教学。学生对这门课的评价大致是好的。

The purpose of this research is to develop various sense presentation means because it improves the desire for the student to be interested in the virtual reality practice, to develop one's imagination and creativity, and to make contents. To be specific, the virtual reality system that present sense of smell and the sense of touch in addition to the presentation of conventional sight and aural is developed, and a comprehensible practice teaching material is developed.We achieved the following results by the research on four years.(1)We developed an unencumbering, localized olfactory display by conveying a clump of scented air from a certain remote place to the user's nose, and applied the smell presentation to the movie. It was clarified that the presence improved by appropriately presenting the smell, and the scene was remaining in the memory, etc.(2)We developed the interface which visualizes the inside of human body division by ultrasonic elasticity image and the Haptic Interface displays hardness distribution of the division using the tactile sense presentation devices.Moreover, the glove type simple force feed-back system for VR environment using artificial muscle was made for trial purposes.(3)We developed the software tool which forms virtual university campus or town, and in which to walk the inside is possible(4)VR practical teaching material was developed using aforesaid developed tool, and it was used for the class. The evaluation for this class by the student is approximately good.
