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:
- an illumination device comprising one or more light sources;
- a sensor, and
- a microcontroller configured to control the sensor and the illumination device to transmit and receive light patterns to perform a light wave communication process to exchange social media codes with other devices and configured to communicate, via communication circuitry, share data to a social media application operating on a host device in response to a synchronize request from the host device, the share data associated with the light wave communication process to exchange the social media codes;
- a battery coupled to the microcontroller and configured to provide power to the microcontroller;
- a memory coupled to the microcontroller and configured to store one or more social media codes;
- and
- the communication circuitry coupled to the microcontroller, the communication circuitry configured to communicate with the host device the share data.

A method for low power light wave communications comprising:
- receiving, at processing circuitry of a peripheral device, a signal to perform a light wave communication process to exchange social media codes with other devices;
- 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 an illumination device and a sensor coupled to the processing circuitry as part for the peripheral device, wherein the illumination device is managed by the processing circuitry to transmit a first social media code associated with a first host device during a first set of time periods 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 a second host device during a first time period when the illumination device is not transmitting;
- storing the second social media code in a memory coupled to the processing circuitry;
- and
- communicating the second social media code to the first host device as part of a synchronization operation with the first host device.
