A system automatically frames locations by detecting a user's presence within a virtual detection space. The system detects sound in the detection space and converts the sound into electrical signals. The electrical signals are converted into a digital signals at common or periodic sampling rates. The system identifies speech segments in the digital signals and attenuates noise like components within or adjacent to them. The system identifies the physical locations of a speech source generating the speech segments and automatically adjusts a camera framing based on the estimated location of the active speech source generating the speech segments.

Auto-framing through speech and video localizations

A system automatically controls an electronic device's audio by detecting an active sound source presence within an auditory detection space. The system transitions the electronic device to selectively output a desired sound when the active sound source presence is detected and detects sound in the auditory detection space. The system enhances sound and transforms it into electrical signals. The system converts the electrical signals into a digital signal and identifies active sound segments in the digital signals. The system attenuates noise components in the digital signals and locates the physical location of the active sound source. It adjusts an output automatically by muting a second sound source in a second detection space.

Active sound control

A computer implemented system controls an electronic device in the absence of a physical contact and/or a radio frequency communication with a user. The system detects the user's presence within a virtual detection range of a camera while the electronic device is in a standby state and transitions the electronic device to an interactive state when the user is detected. The system maintains the interactive state when a detected gesture corresponds to a predefined gesture by processing a comparison of an image of the extended finger against a plurality of images stored in a memory of the electronic device. The system renders a message as a result of the detection of the extended finger and transmits the message as a result of its movement.
