摘要:
Methods and apparatus for indirect illumination in electronic media rating systems are disclosed. A disclosed example method to detect an audience member includes reflecting non-visible light off of a room surface to indirectly illuminate a first portion of the room, receiving reflections of the indirect illumination, processing the received reflections to determine whether an audience member is present in the illuminated portion of the room, and when the audience member is not detected, adjusting a source of the non-visible light to illuminate a second portion of the room.
