System and method for improving orientation data

摘要

Aspects of the disclosure relate to computing technologies. In particular, aspects of the disclosure relate to mobile computing device technologies, such as systems, methods, apparatuses, and computer-readable media for improving orientation data. In one embodiment, the orientation data is generated based on information synchronized to a common sensor input from a plurality of sensor inputs. In one implementation, the common sensor input is from a gyroscope. Furthermore, techniques are provided for improved and novel methods of presenting orientation data to an application layer.
