Abstract
Sensor-assisted location technology is disclosed. Primary location technologies, such as GPS, can be used to determine the current location (e.g., a location fix) of a location-enabled device. In some instances, the primary location technology may be unreliable and/or consume more power than an alternative location technology. Sensors, such as accelerometers, compasses, gyrometers, and the like, can be used to supplement and/or increase the accuracy of location data. For example, a location-enabled device can identify an area with unreliable GPS location data and use sensors to calculate a more accurate location. Areas identified may be crowd-sourced. Sensors can be used to identify errors in the location data provided by primary location technology. Sensors can be used to modify a sampling interval of the primary location technology. Sensor can be used to smooth motion on a user interface between sampling intervals of the primary location technology.
