Abstract: Various implementations disclosed herein include devices, systems, and methods that tracks an electronic device by fusing tracking algorithms. In some implementations, instructions stored on a computer-readable medium are executable to cause obtaining pairs of first position data corresponding to a position of the electronic device in a first coordinate system obtained using a first technique and second position data in a second coordinate system obtained using a second technique. In some implementations, transformations for the respective pairs are determined that provide a positional relationship between the first coordinate system and the second coordinate system. In some implementations, a subset of the pairs is identified based on the transformations, and a combined transformation is determined based on the subset of the transformations. In some implementations, content is provided on an electronic device based on the combined transformation. In some implementations, an update to the combined transformation is gradually applied.

Abstract: Various implementations disclosed herein include devices, systems, and methods that tracks an electronic device by fusing tracking algorithms. In some implementations, at an electronic device having a processor, a method obtains pairs of first position data corresponding to a position of the electronic device in a first coordinate system obtained using a first technique and second position data in a second coordinate system obtained using a second technique. In some implementations, transformations for the respective pairs are determined that provide a positional relationship between the first coordinate system and the second coordinate system. In some implementations, a subset of the pairs is identified based on the transformations, and a combined transformation is determined based on the subset of the transformations. In some implementations, content is provided on the electronic device based on the combined transformation. In some implementations, an update to the combined transformation is gradually applied.
