项目摘要

In the environment for life-sized remote-video cooperative work without distinguishing local from remote, we have verified the importance of symmetry that local and remote users can refer to each other's activity by running three experiments. In the first experiment, we gave the conversation communication-centered task in which the seat positions of local and remote subjects are fixed and there are no physical objects to be shared. Since the images at life size are displayed on LCD panels, the bodies and faces of users are oriented to the LCD panels and we observed that users had active interaction. In the second experiment, We conducted an experiment in which distant users free move around a center table and share a work space on the center table. There, we examined whether showing the upper body of distant collaborators is valuable for group work that requires body movement during their work. A comparative study with and without upper body images indicated that group work were more e … More fficient when upper body images were shown. We infer that upper body images helped them predict and brace for distant collaborator's subsequent movement due to improved similarity. In the third experiment, To alleviate the problem of invisibility that remote gestures often get occluded, transected, and slipped out of one's attention, we proposed a technique, "remote lag," that aims to mitigate the invisibility problems. The technique provides people with an instant playback of the remote gestures to recover from the invisible or missed context of coordination. To examine the effects of the proposed technique to the symmetry property, we studied four-person groups engaging in two mentoring tasks using physical objects with and without remote lags. Our results show that remote lags are effective in alleviating the invisibility problems, resulting in fewer questions/confirmations and redundant instructions during collaboration. Although the technique seems to increase a helper's physical effort, it decreases the helper's overall effort in performing the tasks and alleviates both collaborators' temporal demands. Less

在不区分本地和远程的真人大小的远程视频协作工作环境中，我们通过三个实验验证了对称性的重要性，即本地和远程用户可以参考对方的活动。在实验一中，我们给出了以会话交流为中心的任务，在该任务中，本地和远程主体的座位位置是固定的，没有物理对象可共享。由于真人大小的图像显示在LCD面板上，用户的身体和面部都朝向LCD面板，我们观察到用户进行了积极的互动。在第二个实验中，我们进行了一个实验，在这个实验中，远处的用户可以在中心桌子周围自由移动，并在中心桌子上共享工作空间。在那里，我们研究了显示远程合作者的上半身对于在他们的工作中需要身体移动的小组工作是否有价值。一项有和没有上半身图像的对比研究表明，小组工作更具e-…当显示上半身图像时，效果会更好。我们推断，由于相似性的提高，上半身图像帮助他们预测并准备好远程合作者的后续运动。在第三个实验中，为了缓解远程手势经常被遮挡、横切和滑出人们的视线的隐身问题，我们提出了一种名为“远程滞后”的技术，旨在缓解隐形问题。该技术为人们提供了远程手势的即时回放，以从看不见或错过的协调上下文中恢复过来。为了检验所提出的技术对对称性的影响，我们研究了参与两个辅导任务的四人小组，他们使用具有和不具有远程滞后的物理对象。研究结果表明，远程LAG能有效地缓解协作中的隐蔽性问题，减少问题/确认次数，减少协作过程中的冗余指令。虽然这项技术似乎增加了帮助者的体力努力，但它减少了帮助者在执行任务时的总体努力，并缓解了双方合作者的时间需求。较少
