Mixed-Reality Interfaces for Remote Collaboration

传统的视频聊天提供了远距离协作者之间的音频和视频连接。但是，传统的视频聊天工具对于关注对象和环境的远程协作任务来说是不够的。这样的远程协作任务将变得越来越普遍，包括辅助任务（例如机器维修）、指导任务（例如远程游览）和检查任务（例如设计评论）。传统的视频聊天在为协作者提供以下方面做得很差：(i)关于远程协作者正在做什么的意识信息，例如他们在看哪里，或者他们作为讲话的一部分所做的手势（例如在说“看这个”时指着），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.
