Abstract
A client device, such as a mobile phone or a mobile phone accessory (e.g., phone case), is provided that receives and transmits data (e.g., a social media code) via light wave communication. The light wave communication may comprise structured light (e.g., projected light patterns). The client device may include a lightbox comprised of LEDs located on a back face of the client device.
Claims19
A device comprising:
- a light source;
- a sensor, and
- a microcontroller configured to control the sensor and the light source to transmit and receive light patterns to perform a light wave communication process to exchange social media codes and data:
- a memory coupled to the microcontroller and configured to store the social media codes and data;
- and
- communication circuitry coupled to the microcontroller, the communication circuitry configured to communicate with a social media application the social media codes and data.
3 more elements
A method for low power light wave communications comprising:
- receiving, at processing circuitry of a peripheral device of a housing, a signal to perform a light wave communication process to exchange social media codes with a host device associate with a social media application;
- performing, while the signal is being received by the processing circuitry, a sequence of transmit and detect operations during a plurality of time periods using a light source and a sensor coupled to the processing circuitry as part of the housing, wherein the light source is managed by the processing circuitry to transmit a first social media code associated with the host device during a first time period of the plurality of time periods;
- detecting, while the signal is being received by the processing circuitry, a second social media code received at the sensor from the host device during a second time period of the plurality of time periods when the illumination device is not transmitting;
- and
- storing the second social media code in a memory coupled to the processing circuitry.
