Universal Geospatial Light Switch 

My latest Project Rita addition is an Android app that can turn a light on or off just by pointing the phone at that lamp and hitting on/off. With this app, there is no need to select which light you want to control, your command will always be sent to the light that you are looking at. This was accomplished by surveying the phone’s compass and GPS sensors. Those readings are then processed by a script that understands the layout of the room and then, using x10, sends the command to the appropriate appliance. The entire operation occurs in less than a second. I believe that this same concept could be applied to all other controllable home devices. What if with one app you could flip on a light, turn up one speaker and lower the thermostat by just pointing your phone at the thing you want to change?
