I'm working on a POC to try and find desk occupancy in an office. The aim is to identify which desk is occupied and how many are free and where are the free ones. Also I would like to identify who is sitting at what desk. What are the ways I could do that?
Some of the options I have are to track Bluetooth devices signal strength, Wi-Fi probes, IR or ultrasound options.
One idea is to use active RFID tags and one RFID reader per desk group. A desk group typically contains 4 to 6 desks/laptops.
I'm at the moment trying to determine occupancy through the laptop placed at the desk. As long as laptop is on the desk I'm happy to assume the desk is occupied. Even when the person takes a break this should work. The RFID reader can be integrated to say PI and send the data to cloud to trigger other events. I'm not sure how this will work.
Wi-Fi probes to detect the connections to the nearest router was initial idea. But I have done obligations to track the people without consent. That's parked for now.
Has anyone did this? Any ideas how to get this?
