Patent ID: 8743198

Claim:
A method for detecting occupancy status of a plurality of conference rooms in real time, the method comprising the steps of: monitoring a first output signal of a first sensor; monitoring a second output signal of a second sensor; comparing the first output signal generated by the first sensor and the second output signals generated by the second sensor with one or more predetermined thresholds within a predetermined time; responding to results of the comparison step: (i) falling outside a first predefined value set representing occupancy of a conference room, and (ii) falling outside a second predefined value set representing vacancy of the conference room, determining that the first sensor and the second sensor are insufficient to provide confirmed occupancy status information for the conference room and processing output from one or more image and/or video sensors to obtain confirmed occupancy status information for the conference room; and displaying the confirmed occupancy status information for the room on one or more user devices.
