The mobility and ubiquity of mobile head-mounted displays make them a promising platform for telepresence research as they allow for spontaneous and remote use cases not possible with stationary hardware. In this work we present a system that provides immersive telepresence and remote collaboration on mobile and wearable devices by building a live spherical panoramic representation of a user's environment that can be viewed in real time by a remote user who can independently choose the viewing direction. The remote user can then interact with this environment as if they were actually there through intuitive gesture-based interaction. Each user can obtain independent views within this environment by rotating their device, and their current field of view is shared to allow for simple coordination of viewpoints. We present several different approaches to create this shared live environment and discuss their implementation details, individual challenges, and performance on modern mobile hardware; by doing so we provide key insights into the design and implementation of next generation mobile telepresence systems, guiding future research in this domain. The results of a preliminary user study confirm the ability of our system to induce the desired sense of presence in its users.
移动头戴式显示器的移动性和普及性使它们成为远程呈现研究的有前途的平台,因为它们允许使用固定硬件不可能实现的自发和远程用例。在这项工作中,我们通过构建用户环境的实时球形全景表示来提供沉浸式远程呈现和移动可穿戴设备上的远程协作,远程用户可以实时查看该表示,并且可以独立选择观看方向。然后,远程用户可以通过直观的基于手势的交互与该环境进行交互,就好像他们实际上在那里一样。每个用户都可以通过旋转设备来获得该环境中的独立视图,并且共享其当前的视野以允许简单协调视点。我们提出了几种不同的方法来创建此共享实时环境,并讨论了它们的实现细节、个别挑战和在现代移动硬件上的性能;通过这样做,我们为下一代移动远程呈现系统的设计和实现提供了关键见解,指导该领域的未来研究。初步用户研究的结果证实了我们的系统能够在用户中产生所需的存在感。
