Indoor positioning systems and meeting room occupancy
First Claim
1. A method of determining room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility, the method comprising:
- receiving a request from a computing device for a room occupancy assessment associated with the room;
determining whether the room is occupied, the determining including;
receiving, from at least one wireless device, an indication that a user associated with the at least one wireless device is occupying the room;
obtaining measurements of received signal strength for one or more wireless access point signals detected by the at least one wireless device;
determining that the at least one wireless device has left the room based on detecting that the obtained measurements of received signal strength deviates from a current wireless access point fingerprint for the room by more than a threshold amount; and
updating an assessment of room occupancy based on the determination that the at least one wireless device has left the room, andsending the determination of whether the room is occupied to the computing device.

Abstract
A method of determining room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility. The method may include receiving a request from a computing device for a room occupancy assessment associated with the room. It may further include obtaining location data that correlates to the locations of wireless devices associated with one or more people from the indoor positioning system and determining based on the location data whether the room is occupied. The determination of whether the room is occupied is then sent to the computing device.

8. A server to determine room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility, the server comprising:
-
a network connection to receive a request from a computing device for a room occupancy assessment associated with the room; and a processor to; determine whether the room is occupied, the determining including; receiving, from at least one wireless device, an indication that a user associated with the at least one wireless device is occupying the room; obtaining measurements of received signal strength for one or more wireless access point signals detected by the at least one wireless device; determining that the at least one wireless device has left the room based on detecting that the obtained measurements of received signal strength deviates from a current wireless access point fingerprint for the room by more than a threshold amount; and updating an assessment of room occupancy based on the determination that the at least one wireless device has left the room, and send the determination of whether the room is occupied to the computing device via the network connection. - View Dependent Claims (9, 10, 11, 12, 13)

14. A non-transitory computer-readable medium storing processor-executable instructions for determining room occupancy of a room in a facility having an indoor positioning system with wireless access point fingerprints each correlated to a location in the facility, the processor-executable instructions comprising instructions for:
-
receiving a request from a computing device for a room occupancy assessment associated with the room; determining whether the room is occupied, the determining including; receiving, from at least one wireless device, an indication that a user associated with the at least one wireless device is occupying the room; obtaining measurements of received signal strength for one or more wireless access point signals detected by the at least one wireless device; determining that the at least one wireless device has left the room based on detecting that the obtained measurements of received signal strength deviates from a current wireless access point fingerprint for the room by more than a threshold amount; and updating an assessment of room occupancy based on the determination that the at least one wireless device has left the room, and sending the determination of whether the room is occupied to the computing device.
