Abstract
A method for detecting of a viewing direction of a person includes sensing a speech signal originating from the person using at least one direction-selective microphone so as to produce a microphone signal, detecting the speaking direction of the person using the microphone signal, and deriving the viewing direction from the speaking direction. Also, a device that includes at least one direction-selective microphone configured to detect a speaking direction of the person using speech signals, and a processing unit configured to process the speech signals so as to determine the viewing direction of the person.
