Methods and systems for locating persons and places with mobile devices
Methods, computer readable storage medium, and systems for mobile devices to locate persons or places are described. In a feature, the invention is a method implemented in a server for providing beaconing sequences to the mobile devices for location sharing. In a feature, the invention is a server executing a method of locating a user using a beaconing mobile device. In a feature, the invention is a non-transitory computer readable medium on a server that encodes a program to execute a method on a first mobile device that determine directions and/or distance between the first mobile device and a second mobile device. In a feature, the invention is a server executing a method to remember a place on a mobile device.
1. A method implemented in a server for providing a unique beaconing sequence to a first mobile device and a second mobile device in a geographic area so a first user of the first mobile device and a second user of the second mobile device can locate each other, comprising:
receiving a request from a second mobile device;
reading the request;
reading a beacon history table in response to the request read;
in response to the reading, determining if there are beacon sequences used in the geographic area;
in response to the determining, calculating a unique beacon sequence not used in the geographic area;
adding the unique beacon sequence to the beacon history table; and
sending the unique beacon sequence for display on the first mobile device and the second mobile device, wherein the displayed unique beacon sequence is conspicuous and can be seen by the first user and the second user in the geographic area so that the first user of the first mobile device and the second user of the second mobile device can locate each other.
2. The method of claim 1 , wherein the unique beacon sequence for display on the first mobile device is visibly different from the beacon sequences used in the geographic area.
3. The method of claim 1 , further comprising updating coordinates for a compass on the first mobile device that indicates the location of the second mobile device.
4. The method of claim 1 , further comprising computing an offset for displaying the unique beaconing sequences at that same time on the first mobile device and the second mobile device.
5. The method of claim 1 , further comprising using venue or cell location to determine the geographic area.
