我们提出了一个虚拟水肺潜水系统，使用水下头戴式显示器（UHMD）。该系统有两个优点。首先，通过将潜水获得的失重与防水UHMD呈现的高度沉浸式图像相结合，获得了强烈的真实感。第二，该系统是非常通用的，使得用户可以在诸如游泳池或浅水的容易接近的沃茨中体验该系统。在本文中，我们描述了所提出的系统和水下虚拟现实（VR）内容的创建，以提供潜水体验的设计和实现。拟议的系统包括UHMD与头部跟踪传感器，笔记本电脑，和软管，以保护电缆。UHMD和笔记本电脑通过电缆连接，用于电力、通信和视频传输。每个部分都防水。创建的VR内容可以通过头部跟踪和控制器的操作在虚拟海底世界中自由游泳。我们进行了一个试点实验，以测试所提出的系统，而用户在游泳池中的深度约4米。UHMD被证实在水深约4米处具有足够的防水性。还建议可以创建虚拟水下空间中的水深是用户自己的水深的错觉。
We propose a virtual scuba diving system using an underwater head mounted display (UHMD). This system has two advantages. First, a strong sense of reality is obtained by combining the weightlessness obtained by diving with a highly immersive image presented by a waterproof UHMD. Second, the system is very versatile, such that a user can experience the system in easily accessible waters such as swimming pools or shallow water. In this paper, we describe the design and implementation of the proposed system and the creation of underwater virtual reality (VR) content to provide a diving experience. The proposed system consists of the UHMD with a head tracking sensor, laptop PC, and a hose to protect the cables. The UHMD and laptop PC are connected by cables for power, communication, and video transmission. Each part is waterproof. The created VR content makes it possible to freely swim in the virtual undersea world by head tracking and operation of the controller. We conducted a pilot experiment to test the proposed system while users swam in a pool of about 4 m in depth. The UHMD was confirmed to have sufficient waterproofness at water depth of about 4 m. It is also suggested that it is possible to create the illusion that the water depth in the virtual underwater space is the user’s own water depth.
