Abstract
An apparatus is described that allows for the nonobtrusive recording, from a direct camera perspective, of a subject watching a video or computer display. The device follows the basic principles of a periscope and is useful in a variety of experimental paradigms, particularly those involving the assessment of nonverbal aspects of behavior.
