Title: Rotation-tolerant devices and schemes for pedestrian-dead-reckoning (PDR) location determination

Abstract: Devices, systems, and methods are directed to the determination of current location information of a wireless communication device. Such devices, systems, and methods include a plurality of sensor elements configured to provide orientation parameter information, velocity and/or acceleration parameter information, and directional heading parameter information; a camera mechanism configured to capture images at predetermined intervals of a user's body as the user handles the wireless communication device; orientation logic configured to determine orientation change information attributable to the user's handling, based on the captured images, and provide orientation correction information; and location estimation logic configured to provide current location information based on previous location information, the velocity and/or acceleration parameter information, the directional heading parameter information and/or the orientation parameter information, and the orientation correction information.
