Abstract
System is built using the particle filter (PF) framework which utilizes data from round trip time (RTT) ranging or BLE signal strength to perform both (1) sensing the environment by using the scan data during measurement phase and (2) detect motion state of the user which it utilized during the motion update phase of PF. To detect the motion state of the user the temporal difference of the received ranging scans is used over which is utilized within the PF framework. The primary advantage of the described technique is that the velocity parameter of the PF can dynamically be updated based on the motion state as estimated using ranging scans.
