Patent ID: 8798643

Claim:
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; utilizing a venue network to determine a first fixed geographical location of the mobile communication device at the venue; 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 utilizing a venue network to determine a second fixed geographical location of the mobile communication device at the venue; wherein the mobile communication device is configured to calculate 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 second fixed geographical location for the mobile communication device; wherein each of a plurality of subsequent approximations of the location of the mobile communication device from the latest fixed geographical location is made using the plurality of sensors, the plurality of possible paths, and the error factor which improves accuracy of approximation over time.
