    摘要: An energy based technique to estimate the positions of people speaking from an ad hoc network of microphones. The present technique does not require accurate synchronization of the microphones. In addition, a technique to normalize the gains of the microphones based on people's speech is presented, which allows aggregation of various audio channels from the ad hoc microphone network into a single stream for audio conferencing. The technique is invariant of the speaker's volumes thus making the system easy to deploy in practice.

    摘要: A system that captures both whiteboard content and audio signals of a meeting using a digital camera and a microphone. The system can be retrofit to any existing whiteboard. It computes the time stamps of pen strokes on the whiteboard by analyzing the sequence of captured snapshots. It also automatically produces a set of key frames representing all the written content on the whiteboard before each erasure. The whiteboard content serves as a visual index to efficiently browse the audio meeting. The system not only captures the whiteboard content, but also helps the users to view and manage the captured meeting content efficiently and securely.

    摘要: A media recommendation and sharing technique that employs agents on media players/devices to expand the scope of media sharing scenarios. The technique assists a user in discovering media items, such as, for example, music, recordings, play lists, pictures, video games, on nearby media players or devices (devices which are capable of receiving, storing and playing media) which are interesting to the user. The collaborative media recommendation and sharing technique contemporaneously determines a user's media preferences based on media stored on a pair of media devices and recommends media for potential sharing based on these determined user preferences.

    摘要: Persistent, spatial collaboration on the web supports a free-form, user-intuitive approach to a variety of projects and activities. Users can place differing object types at any time any where on a web page and/or the system can automatically, and with no user effort, affect object placement based on one or more meta data characteristics. A user can, in real-time, see changes made by another user to a web page, and, if desired, react accordingly, enabling true collaboration even if the various users are at remote locations. The flexibility of the methodology and system provides a platform for users to engage in projects and activities in a manner and environment suited to the users' mind sets, creativity, and natural proclivities.

    摘要: A framework for facilitating collaborative interaction between users of a web application is presented. The framework provides persistence and sharing mechanisms for arbitrary application-defined objects. The sharing mechanism is coupled with a consistency mechanism that keeps client states consistent even when users perform conflicting operations. This framework is application-independent in that the persistence, sharing between clients and maintaining a consistent state among the clients is accomplished without the need for specific knowledge of the design of the web application. Thus, web developers can focus on the logic of the application and the UI, instead of spending time designing and implementing collaborative capabilities.

    摘要翻译: 介绍了一种用于促进Web应用程序用户之间的协作交互的框架。 该框架为任意应用程序定义的对象提供持久性和共享机制。 共享机制与一致性机制相结合,即使在用户执行冲突操作时也能保持客户端状态的一致性。 该框架是独立于应用程序的,因为在客户机之间的持久性,共享和维护一致的状态之间完成了这一任务,而不需要Web应用程序设计的特定知识。 因此,Web开发人员可以专注于应用程序和UI的逻辑,而不是花时间设计和实现协作功能。

    摘要: This invention is directed toward a system and method for scanning a scene or object such as a whiteboard, paper document or similar item. More specifically, the invention is directed toward a system and method for obtaining a high-resolution image of a whiteboard or other object with a low-resolution camera. The system and method of the invention captures either a set of snapshots with overlap or a continuous video sequence, and then stitches them automatically into a single high-resolution image. The stitched image can finally be exported to other image processing systems and methods for further enhancement.
