"Looking room" is the space between the subject’s face and the edge of the screen—in the direction he is looking. People on TV rarely look directly at the camera. Instead, they look off-screen slightly. This is true for news interviews, dramas and sitcoms.

(Of course, on some occasions subjects address the camera directly, like presidential speeches and live news reports, but most subjects look off camera slightly.)

Put a little MORE space on the side the subject is looking toward. Give the subject—quite literally—space to look, or looking room.
