Development of remote collaboration system with multiperson view

本地工作人员和远程指导员不能通过自己的视觉和声音直接相互沟通。本地工人在远程指导员的指导下通过远程通信技术进行的工作称为远程协作。在这个项目中，我们部署投影仪摄像机系统（Procams），以某种类型的远程协作，一个真实的对象和地方的指令目标。通过对已有研究的调查，我们发现“胖手指问题”导致了软件开发的延迟和可用性的降低。为了解决这个问题，我们提出了使用可扩展的实施例图像作为指令图像。最后，我们进行了用户研究，以检验建议方法的有效性。结果表明，当远程专家指示小部件时，具有缩放功能的手势图像可以缩短任务完成时间，并为远程专家提供良好的可用性。

A local worker and a remote instructor cannot be communicated each other by own vision and voice directly. Work conducted by a local worker under the instructions of a remote instructor via tele-communication technology is called remote collaboration. In this project, we deploy projector camera system (Procams) to certain type remote collaboration that a real object and places are instruction targets. As we investigate existed researches, we find out that "Fat finger problem" cause delay of completion and derogation of usability. To solve the problem, we propose to use scalable embodiment image as instruction image. Lastly, we conducted the user study to examine the effectively of the proposal method. As a result, gesture image with scaling function make task completion time shorter and provide good usability to remote expert when the remote expert indicate small parts.
