IPSN 2010 Demo: An IP-based Sensor Network with Augmented Reality
At IPSN 2010 in April 2010, we presented a demo that show that sensor data from a Contiki sensor network can be displayed on an Android phone using a technique known as augmented reality (two-page PDF demo abstract here). We just made a brief YouTube video that shows the demo. It should be viewable right on this site, or via this YouTube link. Read on for details of the demo.
The idea of the demo is that each sensor is identified with a black and white square "tag" that is recognized in the phone's video by software running on the phone. The software draws a 3d image on top of the tag, giving the illusion that there is a 3D object on top of the tag when the tag is viewed through the phone's screen. Since all sensors are accessible with HTTP over IP, the phone software simply executes a normal HTTP get to access the sensor data. Thus no sensor network-specific code needs to be on the phone, making software development easier.
