A presentation system capable of detecting one or more gestures and contacts on a touch sensitive display. The presentation system can displaying indicia of such contacts, such as when a user writes with a fingertip, and can remove or alter such indicia responsive to other gestures and contacts. The system can accurately distinguish between types of gestures detected, such as between a writing gesture and an erasing gesture, on both large and small touch sensitive displays, thereby obviating the need for a user to make additional selective inputs to transition from one type of gesture to another. The system can determine how long to keep user annotations displayed during a presentation, based on the nature of the gesture used to make the annotations and the context in which they are made.

Context based annotating in an electronic presentation system

An automatic process for producing professional, directed, production crew quality, video for videoconferencing is described. Rule based logic is integrated into an automatic process for producing director quality video for videoconferencing. An automatic process can include a method for composing a display for use in a video system having an active talker video stream and a panoramic view video stream having more than one person in video. The method can include determining a region of interest in a panoramic view video using motion detection and presence sensors, and preparing the panoramic view video by centering the region of interest and by zooming towards the region of interest, based upon the location of persons in the panoramic view video. The method includes determining placement of panoramic view video on a composite display to prevent the panoramic view video overlaying display of an active talker on the active talker video stream.

Panoramic image placement to minimize full image interference

An automatic process for producing professional, directed, production crew quality, video for videoconferencing is described. Rule based logic is integrated into an automatic process for producing director quality video for videoconferencing. The automatic process uses sensor data to process video streams for video conferencing. A method and system for automatically processing sensor data on room activity into general room analytics for further processing by application of rules based logic to produce production quality video for videoconferencing is described. Sensory devices and equipment, for example motion, infrared, audio, sound source localization (SSL) and video are used to detect room activity or room stimulus. The room activity is analyzed (for example, to determine whether individuals are in the subject room, speaker identification and movement within the room) and processed to produce room analytics. Speaker identification and relative placement information are used to logically depict speakers conversing with one another.

Conversational placement of speakers at one endpoint

An automatic process for producing professional, directed, production crew quality, video for videoconferencing is described. The process includes a method for positioning a 360 degree panoramic strip view of a room. The method includes receiving motion detection data, accepting presence sensor data, receiving video data from cameras related to a room view, and centering individuals in a room view, based on the received motion detection data, the accepted presence sensor data and received video data. The method also includes zooming onto the centered individuals in the room view, obtaining sound source localization data and active talker information, and determining how to arrange the display of individuals in a logical manner that is visually pleasing and aides understanding. Rule based logic is applied to assist with the automatic processing of video into director quality video production. Various video sources may be used as video stream sources for the automated system.
