摘要： The universal input device provides a common user interface for a variety of different computing platforms including printed documents. Using the present system, one may use the universal input device to control various computing devices as well as capture handwritten electronic ink and have the electronic ink be associated with new or stored documents. The universal input device can be identified by a specific identification in order to allow for multiple users to operate on a document and/or within an application program simultaneously or not. An off-set optical system with infrared illumination handles perspective and helps detect positional encoding which can be covered by existing ink under common visible light illumination.

摘要： A method and apparatus for performing EIC pattern analysis is described. Pattern feature extraction is performed followed by EIC symbol segmentation. A system may later use the result from the pattern analysis to determine a location of a captured image in relation to a larger array of EIC symbols.

摘要： Interactive multi-view video presents a new type of video capture system. Many video cameras are allocated to capture an event from various related locations and directions. The captured videos are compressed in control PCs and are sent to a server in real-time. The compressed video can also be transcoded through an off-line compression approach to further reduce the data amount. Users can subscribe to a new type of service that allows users to connect to the servers and receive multi-view videos interactively.
摘要翻译：互动多视角视频呈现出一种新型的视频采集系统。许多摄像机被分配以捕获来自各种相关位置和方向的事件。捕获的视频在控制PC中被压缩，并被实时发送到服务器。压缩视频也可以通过离线压缩方式进行转码，以进一步减少数据量。用户可以订阅一种新的服务类型，允许用户连接到服务器并以交互方式接收多视图视频。

摘要： Interactive multi-view video presents new types of video capture systems, video formats, video compression algorithms, and services. Many video cameras are allocated to capture an event from various related locations and directions. The captured videos are compressed and are sent to a server in real-time. Users can subscribe to a new type of service that allows users to connect to the servers and receive multi-view videos interactively. In addition to conventional playing controls, users can manipulate controls to the camera positions and orientations, select viewing directions and enjoy special effects such as a sweeping effect and a freeze-and-rotate effect, and so on. Interactive multi-view video provides a brand-new experience in watching events.
