Method and System of Estimating Location of Wearable Devices for Location-based Services

摘要

A method and system for estimating the location of a wearable device for location based services are presented. A method for estimating a position of a wearable device for a position-based service proposed in the present invention includes calculating movement direction information of a sensor node from sensor measurement data measured by a user through a portable sensor node, Detecting an entry of the sensor node into the coverage of the corresponding AP by identifying the Bluetooth beacon signal; detecting an entry of the sensor node into the coverage of the corresponding AP; receiving, from the coverage center of the AP, Estimating the distance to the node, and estimating the position of the sensor node by receiving the Bluetooth beacon signal and related information of the sensor node.
