Corporate answer: big, hairy proprietary algorithms. Startup answer: straight magic, yo. Real answer: manual for this week. We're doing a couple things that don't scale to validate a concept.
Total occupancy but larger spaces can be segmented however they might want (order line, dining, bathrooms, bar area, etc.) Just need to separate two sections with a sensor.
