  • Patent number: 11175158
    Abstract: To reduce false counts of a device that counts a user's step count. A pedometer device, a step counting method, and a recording medium are provided. The pedometer devices includes: an acquiring unit that acquires a sensor signal output by a sensor carried by a user; an extracting unit that extracts a feature quantity from the sensor signal; a storage unit that stores a walking model which represents walking motions, the walking model being formed based on a feature quantity extracted from a sensor signal corresponding to a predetermined number of steps of walking; a comparing unit that compares the feature quantity extracted at the extracting unit with the walking model; and a deciding unit that decides whether the user has walked a predetermined number of steps, based on a result of the comparison performed by the comparing unit.

  • Patent number: 10451424
    Abstract: Provided is a position and azimuth detecting device including a photographing instructing unit that acquires an output signal of a sensor mounted on equipment and instructs a photographing apparatus mounted on the equipment to perform photographing based on the output signal, a mark reading unit that reads from a mark included in an image photographed based on the instruction from the photographing instructing unit position information and azimuth information included in the mark, a relative position and azimuth calculating unit that calculates a relative position and a relative azimuth of the equipment to the mark based on a geometric shape of the mark included in the image, and a position and azimuth calculating unit that calculates an absolute position and an absolute azimuth of the equipment based on the position information, the azimuth information, the relative position and the relative azimuth.
