A method and system for determining the mode of motion or conveyance of a device, the device being within a platform (e.g., a person, vehicle, or vessel of any type). The device can be strapped or non-strapped to the platform, and where non-strapped, the mobility of the device may be constrained or unconstrained within the platform and the device may be moved or tilted to any orientation within the platform, without degradation in performance of determining the mode of motion. This method can utilize measurements (readings) from sensors in the device (such as for example, accelerometers, gyroscopes, etc.) whether in the presence or in the absence of navigational information updates (such as, for example, Global Navigation Satellite System (GNSS) or WiFi positioning). The present method and system may be used in any one or both of two different phases, a model building phase or a model utilization phase. |
