Abstract: A view morphing algorithm is applied to synchronous collections of video images from at least two video imaging devices, and interpolating between the images, creates a composite image view of the local participant. This composite image approximates what might be seen from a point between the video imaging devices, presenting the image to other video session participants.

Abstract: A simple and efficient method for producing an obfuscated speech signal which may be used to mask a stream of speech, is disclosed. A speech signal representing the speech stream to be masked is obtained. The speech signal is then temporally partitioned into segments, preferably corresponding to phonemes within the speech stream. The segments are then stored in a memory, and some or all of the segments are subsequently selected, retrieved, and assembled into an obfuscated speech signal representing an unintelligible speech stream that, when combined with the speech signal or reproduced and combined with the speech stream, provides a masking effect. While the presently preferred embodiment finds application most readily in an open plan office, embodiments suitable for use in restaurants, classrooms, and in telecommunications systems are also disclosed.

Abstract: A method and apparatus for providing appropriate output signals to output devices in a teleconference setting is disclosed. Input signals are obtained from input devices, and descriptive information describing the teleconference is received from several sensors. On a substantially continuous basis, using the descriptive information, a desirability is computed for each of several possible output configurations, each output configuration specifying a routing of output signals to output devices. The most desirable output configuration is then selected, and output signals are provided to output devices as specified by the selected output configuration.
