Absolute orientation of a mobile device using earth's coordinates

The patent US12044547B1 outlines a method for determining the absolute orientation of a mobile device by aligning its orientation sensor with the Earth's coordinate system. The process begins by accessing the initial orientation from the device's orientation sensor and prompting the user to move the device in that direction. As the device is moved, a position sensor captures a set of position information, which is then used to determine a vector of movement in the Earth's coordinate system. This vector indicates both the axis and direction of movement. The method calculates the difference between this vector and the initial orientation vector, using this difference to establish an orientation difference between the Earth's coordinate system and that of the mobile device. The absolute orientation is then produced by adding this orientation difference to the live orientation from the sensor, which is subsequently returned to an application running on the device.

The claims further detail the technical aspects of the method, including the use of linear regression to analyze the captured position data, which is represented in a two-dimensional coordinate space defined by latitude and longitude. The method allows for the collection of position information until certain stopping conditions are met, such as time, distance, or error estimates. Additionally, the patent specifies that the orientation sensor may not be capable of determining absolute orientation on its own, or it may be limited by the device's operating system. The application of this technology is particularly relevant for augmented reality applications, where the live absolute orientation enhances the user experience by providing a more accurate augmented reality view on the device's display screen.
