Abstract:
1. A method, comprising: receiving, by a mobile device equipped with a global positioning system, global positioning system information identifying a destination location; determining, by the mobile device, a path of travel to the destination location from a current location based on the global positioning system information; computing, by the mobile device, a first location on the path of travel at which a first turn should be made in order for the mobile device to stay on the path of travel; prior to the mobile device arriving at the first location, aurally presenting by the mobile device a first turn instruction that provides aural information about a distance to the first turn; computing, by the mobile device, a second location on the path of travel at which a second turn should be made subsequent to the first turn in order for the mobile device to remain on the path of travel; determining, by the mobile device, a travel distance between the first location and the second location based on the global positioning system information; determining, by the mobile device, a speed of travel based on the global positioning system information; computing, by the mobile device, a window of time between the first location and the second location based on the travel distance and the speed at which the mobile device travels; querying, by the mobile device, a database stored in memory for the window of time, the database storing associations between different names of advertisements and different windows of time; retrieving, by the mobile device, one of the different names of the advertisements that matches the window of time; retrieving, by the mobile device, an electronic file associated with the one of the different names of the advertisements; and processing, by the mobile device, the electronic file for aural presentation during the window of time between the first location and the second location before aurally announcing the second turn.
