Abstract:
1. A computer-implemented method of assessing whether a mobile device is in a geospatial area, the method comprising: receiving, at a mobile device, a representation of a non-circular geospatial zone; causing storage of the representation of the non-circular geospatial zone in a memory of the mobile device; determining, based at least in part on the non-circular geospatial zone, an outer circular boundary entirely encompassing the non-circular geospatial zone, wherein the outer circular boundary is defined by at least a centroid of the non-circular geospatial zone and a maximum radius; determining, based at least in part on the non-circular geospatial zone, an inner circular boundary entirely encompassed within the non-circular geospatial zone, wherein the inner circular boundary is defined by at least the centroid of the non-circular geospatial zone and a minimum radius; computing a current distance of the mobile device from the centroid of the non-circular geospatial zone; and in response to a determination that the computed current distance both exceeds the minimum radius and does not exceed the maximum radius, utilizing the non-circular geospatial zone to determine a context of the mobile device.
