Abstract: Technologies for determining a user's location by a mobile computing device include detecting, based on sensed inertial characteristics of the mobile computing device, that a user of the mobile computing device has taken a physical step in a direction. The mobile computing device determines a directional heading of the mobile computing device in the direction and a variation of an orientation of the mobile computing device relative to a previous orientation of the mobile computing device at a previous physical step of the user based on the sensed inertial characteristics. The mobile computing device further applies a Kalman filter to determine a heading of the user based on the determined directional heading of the mobile computing device and the variation of the orientation and determines an estimated location of the user based on the user's determined heading, an estimated step length of the user, and a previous location of the user at the previous physical step.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of geofencing. For example, an apparatus may include a geofencing detector to trigger a first location scan for a first location fix of a mobile device; and a location calculator to dynamically update an activity-based location area of the mobile device relative to the first location fix, based on a plurality of detected activity states of a user of the mobile device, the plurality of detected activity states corresponding to a plurality of detection points subsequent to the first location scan, wherein the geofencing detector is to trigger a second location scan for a second location fix of the mobile device, based on the activity-based location area and a geofencing boundary.
