Abstract: A computer network-based distributed presentation system and process is presented that controls the display of one or more video streams output by multiple video cameras located across multiple presentation sites on display screens located at each presentation site. The distributed presentation system and process provides the ability for a user at a site to customize the screen configuration (i.e., what video streams are display at any one time and in what format) for that site via a two-layer display director module. In the design layer of the module, a user interface is provided for a user to specify display priorities dictating what video streams are to be displayed on the screen over time. These display priorities are then provided to the execution layer of the module which translates them into probabilistic timed automata and uses the automata to control what is displayed on the display screen.

Abstract: An event-based system and process for recording and playback of collaborative electronic presentations is presented. The present system and process includes a technique for recording collaborative electronic presentations by capturing and storing the interactions between each participant and presentation data where each interaction event is timestamped and linked to a data file comprising the presentation data. The present system and process also includes a technique for playing back the recorded collaborative electronic presentation, which involves displaying the presentation data in an order it was originally presented and reproducing the recorded interactions between each participant and the displayed presentation data at the same point in the presentation that they were originally performed, based on the aforementioned timestamps.

Abstract: A system and process for providing an interactive computer network-based virtual team worksite that combines data storage, team members' presence information, interaction tools and a past history log into one virtual complex is presented. Generally, this is accomplished by integrating a shared data module, a unique presence module and various conferencing tools such as a collaborative presentation module and chat module into a single worksite assessable over a distributed computer network. Thus, everything a team would need related to a project is available in this integrated place. A team member who logs onto the worksite can input data and commands using the worksite window sectors to interface with other team members also logged on to the worksite and to interact with the displayed data in the collaborative presentation sector.

Abstract: Computer-readable media, computer systems, and computing devices for initiating a search function, such as presentation of a search box or initiation of a search, is provided. In one embodiment, the method includes detecting movement of a selector from within a display area to an edge of the display area. Such a selector can be controlled by an input device coupled to a user device. In response to detecting movement of the selector from within the display area to the edge of the display area, a search-query input area associated with a search engine is presented within a display screen view.

Abstract: Systems and methods for detecting people or speakers in an automated fashion are disclosed. A pool of features including more than one type of input (like audio input and video input) may be identified and used with a learning algorithm to generate a classifier that identifies people or speakers. The resulting classifier may be evaluated to detect people or speakers.

Abstract: Background blurring is an effective way to both preserve privacy and keep communication effective during video conferencing. The present image background blurring technique is a light weight real-time technique to perform background blurring using a fast background modeling procedure combined with an object (e.g., face) detector/tracker. A soft decision is made at each pixel whether it belongs to the foreground or the background based on multiple vision features. The classification results are mapped to a per-pixel blurring radius image to blur the background. In another embodiment, the image background blurring technique blurs the background of the image without using the object detector.
