1. A computer-implemented method for locating an indoor object based on a radio frequency (RF) coordinate signal from an RF coordinate estimation unit, and at least one detecting signal from a motion sensor array upon detection of movement of the indoor object, the RF coordinate signal carrying information of an RF coordinate on a coordinate plane estimating a position of the indoor object, said method comprising:

  • a) receiving the RF coordinate signal and the detecting signal;

    b) providing information of a located region on the coordinate plane with reference to the RF coordinate and the detecting signal;

    c) obtaining a motion sensor coordinate on the coordinate plane according to the information of the located region;

    d) providing weights for the RF coordinate and the motion sensor coordinate;

    e) applying the weights to the RF coordinate and the motion sensor coordinate, respectively; and

    f) combining the weighted RF coordinate and the weighted motion sensor coordinate to generate a fused coordinate on the coordinate plane corresponding to the position of the indoor object.
