    • A system that facilitates interaction with a 3-dimensional (3-d) virtual environment is described. In this system, a controller device provides information associated with the 3-d virtual environment to a first display. Furthermore, the system includes at least one portable electronic device, which includes a second display and a 3-d motion sensor that detects motion of the portable electronic device, such as: linear motion, rotational motion and/or a gesture. This portable electronic device communicates the detected motion to the controller device. In response, the controller device provides a subset of the 3-d virtual environment and associated context-dependent information to the portable electronic device, which are displayed on the second display.
    • 描述了有助于与三维(3-d)虚拟环境交互的系统。 在该系统中,控制器设备向第一显示器提供与3-d虚拟环境相关联的信息。 此外,该系统包括至少一个便携式电子设备,其包括第二显示器和检测便携式电子设备的运动的3-d运动传感器,例如:直线运动,旋转运动和/或手势。 该便携式电子设备将检测到的运动传送到控制器设备。 作为响应,控制器设备向第二显示器上显示的便携式电子设备提供3-d虚拟环境的子集和相关联的上下文相关信息。

    • One embodiment of the present invention provides a system for tracking and distributing annotations for a video stream. During operation, the system receives, at an annotation server, the video stream originating from a remote field computer, extracts a number of features from the received video stream, and identifies a group of features that matches a known feature group, which is associated with an annotation. The system further associates the identified group of features with the annotation, and forwards the identified group of features and the annotation to the remote field computer, thereby facilitating the remote field computer to associate the annotation with a group of locally extracted features and display the video stream with the annotation placed in a location based at least on locations of the locally extracted features.
    • 本发明的一个实施例提供了一种用于跟踪和分发用于视频流的注释的系统。 在操作期间,系统在注释服务器处接收来自远程现场计算机的视频流,从接收到的视频流中提取多个特征,并且识别与已知特征组相匹配的一组特征,其与 注释。 所述系统还将所识别的特征组与所述注释相关联,并且将所识别的特征组和所述注释转发到所述远程现场计算机,从而便于所述远程现场计算机将所述注释与一组本地提取的特征相关联并且显示所述视频 至少基于本地提取的特征的位置将注释放置在位置中的流。
