Abstract
A light source emits a modulated light, and a radio-frequency transceiver disposed therewith emits a radio-frequency signal. A mobile device may receive either or both signals and determine its position based thereon. The light and radio-frequency sources may be disposed in node in a network of said sources, and the nodes may communicate via the radio-frequency transceivers.
Claims11
A mobile device, comprising:
- a radio frequency transceiver;
- a hardware user interface;
- a camera configured to receive a visual light communication;
- and
- a processor configured to:
- receive a radio frequency identifier of a lighting device via the radio frequency transceiver;
- receive via the camera a modulated light identifier of a lighting device in the vicinity of the mobile device;
- combine the radio frequency identifier and the modulated light identifier to form a combined lighting device identifier;
- and
- receive position information related to the mobile device based on the combined identifier.
7 more elements
A method, comprising:
- receiving an identifier of a lighting device via a radio frequency transceiver of a mobile device;
- receiving at a camera of the mobile device an optical identifier of a lighting device;
- combining the lighting device identifier and the optical identifier to form a combined identifier of the light device in a vicinity of the mobile device;
- sending the combined identifier to a host processor;
- and
- receiving position information based on the combined identifier sent to the host processor.
3 more elements
A system, comprising:
- a first lighting device comprising:
- a first radio frequency transceiver;
- a first light source configured to output a modulated light signal unique to the first lighting device, the first lighting device configured to:
- transmit a first radio frequency identifier identifying the first lighting device, via the first radio frequency transceiver in a first radio frequency detection area, and
- emit a first modulated light signal from the first light source, in a first modulated light detection region;
- a second lighting device comprising:
- a second radio frequency transceiver;
- a second light source configured to output a second modulated light signal unique to the second lighting device, the second lighting device configured to:
- transmit a second radio frequency identifier identifying the second lighting device, via the radio frequency transceiver in a second radio frequency detection area, and
- emit a second modulated light signal from the second light source in a second modulated light detection region, wherein:
- the first radio frequency detection area and the second radio frequency detection area overlap one another;
- and
- the first modulated light detection region and the second light detection region are non-overlapping;
- and
- a mobile device, comprising:
- a processor,
- a radio frequency transceiver;
- and
- a camera,
- the mobile device configured to:
- receive the first radio frequency identifier via the mobile radio frequency transceiver, identifying the first lighting device;
- receive the second radio frequency identifier via the mobile device radio frequency transceiver identifying the second lighting device identifier;
- receive via the camera either the first or the second modulated light signal;
- and
- in response to receiving a first modulated light signal by the camera, the first radio frequency identifier, and the second radio frequency identifier, determine that the mobile device is in a position closer to the first lighting device than to the second lighting device.
