Abstract
When an optical motion detector of a room device detects movement in a room in which it is installed, the room device transmits a radio message including its position. Upon receiving the radio message, a mobile device measures the signal strength to determine whether it is high. If the movement detected by the optical motion detector correlates chronologically with movement detected by an inertial movement sensor of the mobile device, the mobile device concludes that the mobile device is located in the room or in proximity of the position of the room device. The identity of the mobile device is protected, as no server or other device is required for positioning to which the mobile device would have to disclose the identity, position or sensor information thereof.
