Study of tactile display by vortex air cannon.

本文提出了一种新型的教育或娱乐用涡流空气炮系统的触觉显示，称为气压式面部触觉显示。3D图像显示系统正越来越多地在学校和特殊展览中短期内以有限的规模使用。在这种情况下的设置下，所使用的内容仅限于图像和声音，可以很容易地四处移动。因此，这项研究集中在一种使用涡流空气炮作为触觉显示器的方法，该方法易于设置。由于涡流空气炮的结构和控制简单，很容易实现小型化。本研究还将人脸作为触觉显示区域。人的脸具有与手相同的触觉分辨率。因此，控制涡流空气炮的压力可以使触觉显示器产生各种印象。此外，由于人脸总是暴露在外，涡流空气炮的触觉显示可以直接投射到皮肤表面。当影院上映图像时，观众中的每个人都面对着屏幕。而且，在香水和雾气显示研究中证明，涡流空气炮在可达距离和精度方面具有更高的性能。如果可以控制涡流空气炮的方向和气压，就可以在他们的脸上显示相同的触觉刺激，而不管他们的位置。

Novel tactile display using vortex air canon system for education or entertainment use called the air pressured facial tactile display is proposed in this paper.3D image display systems are being used increasingly in schools and special exhibitions for a short term on a limited scale. Under the set up in such circumstances the content being used are limited to images and sounds which can be moved around easily. This study, therefore, focused on a method of using a vortex air cannon as the tactile display that is easy to set up. As the structure and control of a vortex air cannon is simple, it can be easily miniaturized. This study also focused on the human face as the tactile display area. The human face has a tactile resolution equivalent to the hand. Thus, controlling the pressure of vortex air cannon allows a tactile display generating various impressions. Also, since the human face is always exposed, tactile display by a vortex air cannon can be projected directly onto the surface of the skin. When images are shown in theaters, everyone in the audience is facing the screen. And, a vortex air cannon, as proven in fragrance and fog display studies, has a higher performance in reachable distance and accuracy. If the direction of the vortex air cannon and the air pressure can be controlled, it is possible to display the same tactile stimulation onto their faces regardless of their location.
