Claim Text:
1. A method for wayfinding at a venue, the method comprising: launching a mobile application on a mobile communication device within a venue, the mobile application for wayfinding at the venue; receiving a beacon signal from a first BLUETOOTH low energy beacon at the mobile application; transmitting a first message from the mobile application to a wayfinding server, the first message comprising an identifier for the first BLUETOOTH low energy beacon and an identifier for the mobile application; determining a first fixed geographical location for the mobile communication device at the wayfinding server based on the first message; transmitting the first fixed geographical location from the wayfinding server to the mobile application; tracking a path of the mobile communication device from the first fixed geographical location utilizing a plurality of sensors of the mobile communication device, wherein the plurality of sensors of the mobile communication device comprises an accelerometer, a magnetometer and a gyroscope, wherein the accelerometer is configured to determine a movement of the mobile communication device and an orientation of the movement, wherein the magnetometer is configured to determine a true north heading of the mobile communication device, and wherein the gyroscope is configured to determine an orientation of the mobile communication device; and receiving a beacon signal from a second BLUETOOTH low energy beacon at the mobile application; transmitting a second message from the mobile application to the wayfinding server, the second message comprising an identifier for the second BLUETOOTH low energy beacon and the identifier for the mobile application; determining a second fixed geographical location for the mobile communication device at the wayfinding server based on the second message; transmitting the second fixed geographical location from the wayfinding server to the mobile application; utilizing the accelerometer of the mobile communication device to adjust a location of the mobile communication device from the first fixed geographical location; requesting a supplemental first fixed geographical location for the mobile communication device; and calculating an error factor for the tracking the path of the mobile communication device from the first fixed geographical location for the mobile communication device to the supplemental first fixed geographical location for the mobile communication device, wherein the error factor is utilized for the tracking the path of the mobile communication device.
