Mixed-Reality Interfaces for Remote Collaboration

传统的视频聊天在相距遥远的协作者之间提供音频和视频连接。但是，传统的视频聊天工具不适用于专注于对象和环境的远程协作任务。这样的远程协作任务将变得越来越常见，包括协助任务(例如机器维修)、指导任务(例如远程参观)和检查任务(例如设计评论)。传统的视频聊天在向合作者提供以下方面做得很差：(I)关于远程合作者正在做什么的意识信息，例如他们正在看哪里，或者他们作为语音的一部分正在做出的手势(例如，一边指着一边说“看这一个”)，以及(Ii)对远程空间的理解。这些接口至关重要，因为远程对象和位置已成为移动设备支持的协作的主要焦点。

Conventional video chat provides audio and video connection between distance-separated collaborators. But conventional video chat tools are inadequate for remote collaboration tasks that focus on objects and environments. Such remote collaboration tasks will increasingly become commonplace, including assistance tasks (e.g. machine repair), guidance tasks (e.g. remote tour), and inspection tasks (e.g. design critique). Conventional video chat does a poor job of giving collaborators: (i) awareness information about what a remote collaborator is doing, such as where they are looking, or the hand gestures they are making as part of speech (e.g. pointing while saying “Look at this one”), and (ii) an understanding of the remote space. These interfaces are critical, because remote objects and locations have become be the main focus of collaboration enabled by mobile devices.
