    The audiator: a device-independent active marker for spatially aware displays



    The LightSense system [Olwal 2006] promotes printed public information sources, such as maps, into interactive surfaces enriched with digital information, which is accessed through a spatially aware display [Fitzmaurice 1993]. Using outside-in tracking, LED lights on cell phones are located using an instrumented environment with either a combination of a computer/camera or microcontroller/photosensors. The location is continuously sent to the phone over Bluetooth, such that context-sensitive information can be shown as the device is moved by the user.
