An actographic bed coupled with an electronic logic network was constructed to detect major body movements usually associated with changes in sleep posture. These body movements also triggered the infra‐red photographic system. Recordings of these movements by means of transducers attached to the actographic bed on the sleep electroencephalograms permitted an analysis of body movements in relation to sleep stages and time of night. The system remained reliable over long periods of use, and did not interfere with sleep.
