  • Method, apparatus and computer program product for orienting a smartphone display and estimating direction of travel of a pedestrian
    Patent number: 9544740
    Abstract: Method, apparatus, and computer program product embodiments provide position determination. An example method embodiment comprises measuring in a mobile device, acceleration in mutually orthogonal x and y directions in a horizontal plane and in a vertical direction, due to walking motion of a user holding the device; computing a Fourier transform of the measured acceleration in the vertical direction and determining a frequency of acceleration in the vertical direction having a maximum amplitude; computing a Fourier transform of the measured acceleration in the x direction and in the y direction and determining a frequency of acceleration in the x and y directions corresponding to the maximum amplitude frequency of acceleration in the vertical direction; and computing a direction of walking motion of the user, based on the determined frequency of acceleration in the x and y directions corresponding to the maximum amplitude frequency of acceleration in the vertical direction.
