摘要
An active indoor location sensing technique is presented for smartphones and other types of mobile devices without requiring any additional sensors or pre-installed infrastructure. The main idea is to actively generate acoustic signatures by transmitting a sound signal with a phone's speakers and sensing its reflections with the phone's microphones. This active sensing achieves finer-grained control of the collected signatures than the widely-used passive sensing.
