Abstract

A system aims a device to be targeted responsively to sound emanating from various possible sound sources. For example, the system could be used to aim a video camera (4) or a light at a current speaker (6B) such as in a conference or a debate. The control system is responsive to the duration of continuous sound emanation from a new source (6A) of sound and an angular difference between a current target (6B) and the new source of sound (6A). When each exceeds a threshold, the camera (4) will be re-aimed. Sound does not have to perfectly continuous such that short pauses (as for breathing) are not responded to as a break in continuous speech.
