US20150347850 illustrates an IoT (Internet of Things) AR (Augmented Reality) application in a smart home. A smart home IoT device communicates via a local network to a user AR device (e.g., smartphone) for providing the tracking data. The tracking data describes the smart home IoT device. The AR devices can recognize the smart home IoT device in the camera view based on the tracking data. Once the smart home IoT device is identified in the camera view, the AR application can augment the camera view with additional information and control interface about the smart home IoT device. The user can control the smart home IoT device using the AR device.
