Abstract:
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; communicating from the mobile application with a venue network through a wireless access point of the venue network; utilizing a venue network to determine a first fixed geographical location of the mobile communication device at the venue; inputting on the application a second fixed geographical location within the venue; guiding an end user of the mobile communication device from the first fixed geographical location to the second fixed geographical location in the venue 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 suspending a plurality of request transmissions from the mobile communication device while the accelerometer sensor of the mobile communication device indicates a lack of movement; wherein the mobile communication device is configured to calculate an error factor for the guiding the end user of the mobile communication device from the first fixed geographical location to the second fixed geographical location; 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.
