Hi -- > Is there a bluetooth device and software that is able to track my > movement (cellphone) within a room in real time, for example if my > cellphones bluetooth is switched on and i am walking around a room can > the bluetooth device on my computer detect that i am in a different > position as i walk around (can it measure the distance of where i am > from the computer and can it handle multiple cellphones) I don't believe you can do this terribly easily with Bluetooth but perhaps you'd like to look at this project with similar goals: http://events.ccc.de/congress/2006/Sputnik It worked pretty well. It doesn't use triangulation of timing like GPS, it works on signal strengths and so is a bit approximate.
