Methods Setting

In this article, we describe the rationale and design of an automated system for visualizing the peri-operative process based on collected real-time sensory data: video from within operating rooms and patient vital signs. The system, called Video Board System (VBS), provides real-time status information about operating rooms (OR), including major event land-marks (patient entrance to and exit from the OR) and rich contextual information about OR status to differ-ent decision makers. In addition to meeting above design objectives, the system also addressed informa-tion security, video-image quality, image update fre-quency, and impact on data distribution network
