We developed and studied two new telepointers, an aggregate pointer and a delegate pointer, to support remote collaboration and group awareness in distributed learning environments so many people can more easily communicate with each other. We conducted experiments that showed people are not good at accurately locating the focus of multiple telepointers. The aggregate pointer makes it easier for people to understand the overall direction of others' intentions or interests, help people share more accurate aggregated information, and complement individual telepointers. The aggregate pointer is effective at giving feedback of the aggregated information of many telepointers, but it is difficult to use the aggregate pointer to affect specific objects, for example pushing a button.To solve this problem, we developed the delegate pointer. It enables people to delegate the rights of their own pointers to the pointer of someone they trust. The delegate pointer promotes group collaboration through a fair voting system in interactive environments populated by many people. We showed that there are different methods to control pointer delegation and determined the features of these methods. We also developed a multimodal toolkit library for remote collaboration and group awareness. The toolkit supports multicast communications, multiple telepointers, video processing, and tactile feedback of pointers and videos. Using the toolkit, we developed remote collaboration tools for 2D and 3D video communications that support group awareness. The use of 3D pointers and annotations on autostereoscopic displays was evaluated using a prototype personal 3D videoconferencing tool that we had developed. The evaluation showed that 3D pointing and annotating operations of the tool are easy to understand and easy to use.

我们开发并研究了两个新的远程指针，一个聚合指针和一个委托指针，以支持分布式学习环境中的远程协作和组意识，以便许多人可以更容易地相互通信。我们进行的实验表明，人们并不擅长准确定位多个传话筒的焦点。聚合指针使人们更容易理解他人意图或兴趣的总体方向，帮助人们分享更准确的聚合信息，并补充个人指针。聚合指针可以有效地反馈许多指针的聚合信息，但是很难使用聚合指针来影响特定的对象，例如按下按钮。为了解决这个问题，我们开发了委托指针。它使人们能够将自己的指针的权利委托给他们信任的人的指针。在多人聚居的互动环境中，委托指针通过公平的投票系统促进小组协作。我们展示了控制指针委托的不同方法，并确定了这些方法的特点。我们还开发了一个用于远程协作和组感知的多模式工具包库。该工具包支持多播通信、多指针、视频处理以及指针和视频的触觉反馈。使用该工具包，我们开发了用于支持团队意识的2D和3D视频通信的远程协作工具。使用我们开发的原型个人3D视频会议工具，评估了在自动立体显示器上使用3D指针和注释的情况。评价结果表明，该工具的三维指向和标注操作简单易懂，易于使用。
