Animations of bluetooth network traces


The animations below are based on a dataset managed by and downloaded from CRAWDAD. The data was originally collected as part of the Reality Mining Project at MIT in which 100 participants were given bluetooth-enabled mobile phones and encouraged to carry them around over the course of the 2004-2005 academic year. Special software on the phones recorded bluetooth connections between devices. Specifically, if a mobile phone was within range of another and a connection was established then the start and end times of the connection and the device identification number were logged.

The visualisations were created using SoNIA, a Java-based social network animation tool. The circles represent mobile phones and the lines drawn between circles represent active, bi-directional bluetooth connections. The position of the circles, the distance between them and the length of the lines bear no relation to the real physical location of the phones, although for bluetooth devices to establish a connection they generally have to be within a range of approximately 10 metres. Each movie shows the connections between phones within a specific time frame and the duration of the connections between the mobile phones is directly proportional to the duration of the links between circles in the clip.
