Abstract:
Systems and methods are provided for an advanced pedometer, which may include: a first accelerometer for providing first acceleration information for a first direction; a second accelerometer for providing second acceleration information for a second direction; a third accelerometer for providing third acceleration for a third direction; a clock for providing time information associated with the first acceleration information, the second acceleration information, and the third acceleration information; and a processing module comprising one or more processors. The processing module may be to execute computer-executable instructions to: determine fourth level acceleration information for a plane using the first acceleration information for the first direction, and the second acceleration information for the second direction, where the plane is defined by the first direction and the second direction; and estimate a distance traveled using the fourth level acceleration information, the third acceleration information, and at least a portion of the time information.
