Systems, apparatus, and methods are disclosed for accurately identifying one or more mobile thing motion activity (MTMAs; e.g., stationary, walking, running, biking, driving, etc.) associated with a mobile thing (MT; e.g., a person) using sensor data from one or more sensors associated with a wireless communication device (WCD) transported by the MT and for facilitating purchase of a good or service based at least in part upon the one or more MTMAs and one or more predefined user preferences. The sensor data from the one or more sensors (e.g., accelerometer, gyroscope, magnetometer, etc.) is designed to produce data indicative of physical movement of the WCD in three dimensions of a three dimensional (3D) space. In some embodiments, the one or more MTMAs are a plurality of instances of the same MTMA (e.g., a plurality of running sessions) and the purchase of the good or service (e.g., new running shoes) is initiated when a total time duration or total travel distance exceeds a predefined threshold (e.g., 300 hours or 500 miles, respectively), as defined by the WCD user in a predefined preference.

Disclosed is a method for generating an estimation of earth's gravity. The method includes: obtaining one or more acceleration data values and one or more orientation data values over a period of time; generating magnitude of orientation change from the orientation data values; determining a stability value based on the acceleration data values and the magnitude of orientation change; comparing the determined stability value to a threshold value; and generating an estimation of earth's gravity over the period of time on the basis of the acceleration data values if the comparison indicates that the determined stability value is below the threshold value. Also disclosed is an apparatus implementing the method.

A miniaturized inertial measurement and navigation sensor device and a flexible, simplified GUI operating in real time are provided to create an optimum IMU/INS. The IMU includes multiple angle rate sensors, accelerometers, and temperature sensors to provide stability device. A navigation GUI tests algorithms prior to embedding them in real-time IMU hardware. MATLAB code is converted to C++ code tailored for real-time operation. Any point in the algorithm suite structure can be brought out as a data channel to investigate the pattern of operation. The data channels permit zooming in on the algorithm's operation for the open-loop angle, velocity and position drift measurements for bias-compensated channels. The GUI can be used to verify results of an extended Kalman filter solution as well as the implementation of the real-time attitude and heading reference system. When the code has been verified, it is compiled and downloaded into a target processor.

A method and system are provided for determining a heading angle of a user of a portable electronic device in an indoor environment. In an embodiment, the device collects rotational movement information indicative of rotational movement of the device and determines a first heading angle of the device. The first heading angle is determined by using the downward direction of the device to determine the vertical angular rate in the horizontal plane, and integrating the vertical angular rate to form the first heading angle. The device collects first direction information from a first direction sensor and second direction information from a second direction sensor and uses it determine which of the first and second direction information is an outlier, e.g., inaccurate due to an occurrence of a disturbance. The device then corrects the heading angle by comparing the heading angle to the first and second direction information.
