1. A method comprising:
determining a context of a mobile device; and determining if the determined context is accurate using a plurality of measurements of atmospheric pressure from an atmospheric pressure sensor of the mobile device; wherein determining if the determined context is accurate comprises: generating the plurality of measurements of atmospheric pressure using the atmospheric pressure sensor of the mobile device during a time range; determining a characteristic of the plurality of measurements of atmospheric pressure by determining a distribution of the plurality of measurements of atmospheric pressure;
determining if the characteristic meets a threshold condition by determining if a percentage amount of a spread of the distribution is greater than a threshold amount of atmospheric pressure; upon determining that the percentage amount of the spread is greater than the threshold amount of atmospheric pressure, determining that the context is accurate; and generating an output specifying that the context is accurate.
