Hi,

Just hoping to get some ideas and advice on a project i'm doing. I am looking to track the movements of a participant in a project and want to create a patch that will allow them to be tracked by connecting a ultrasonic range finder, compass sensor and accelerometer and mapping out the area they will be walking around. I was wondering the best way to go around this and what calculations would be useful for me to use? I am then going to be using this information into a visual mapping and create a gps like visualisation.

Thanks very much in advance!
