An application is introduced to control home appliances on the basis of an indoor user localization system using Wi-Fi signals. In this application, the user heads his smart device (smartphone or tablet) to the appliance needed to control like bulb, television, air conditioner, fan, security camera… just similarly to using a remote control. On the basis of the user location provided by a localization system, the heading orientation and the tilt angle of his smart device, the system will detect the target appliance by regarding a predefined map, and show the corresponding control panel on the smart device’s display, allowing the user to apply control command to the appliance. A small program installed on the smart device regularly scans the signal strengths to surrounding Wi-Fi access points to enable calculating the user location in 3D space by a robust hybrid method, which is based on both geometrical and probabilistic approaches. A central server is set up to realize the control commands received from the smart device.
