Purpose: The invention relates generally to videoconferencing and specifically to a telepresence system intended to improve interaction quality and communication effectiveness between people separated by distance. It addresses camera-placement problems that cause a remote user to appear to be looking down, up, or to the side rather than making eye contact, and it notes behavioral research on interpersonal distance and eye contact.

Plain-language scope (from the excerpt): The system is described as automatically matching the eye level of a remote user's image shown on a telepresence device's display with the eye level of a local subject; matching the device's display height to the local subject; maintaining a selected distance from the local subject as that subject moves in real time; and recognizing gaze direction to match eye contact between the remote user and the local subject. The background discusses prior approaches including beam-splitter/telepresence-robot systems, 3D head/eye re-centering, an E-Travel surrogate robot, and haptic-feedback telepresence, while stating that none automatically match robot height or continuously maintain a selected distance to a moving subject.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
