| Abstract: The various technologies presented herein relate to determining a
location of an individual, or an object, when a GPS may be
unavailable/occluded. Readings from a plurality of sensors on a mobile
device can be generating a plurality of data (e.g., speed, motion,
temperature, biometric, etc.) which can be combined to generate a
probability of a user of the mobile device being at a particular
location, or not. Sensor readings can be weighted to enable sensors
having a large effect on a degree of confidence of the probability of the
user being determined to be at a location being given priority (e.g.,
battery priority) versus those sensors which have lesser effect on the
degree of confidence. With the user determined to be at a location,
information, a notification, an instruction, etc., can be presented to
the user, via the mobile device. |
