    Abstract: Techniques are disclosed for position-based actions using light-based communication (LCom). LCom signals can be used to encode or otherwise provide data which in turn can be used to help determine the position of a device receiving those LCom signals. Therefore, LCom can be used to facilitate various actions based on, for example, the position of an LCom receiver determined using data received via the LCom signals. There are numerous use cases for position-based actions using LCom, such as security applications, check-in applications, payments based on location, permissions, and access to information that can all be tied to a location. Actions may include temporarily disabling or enabling the LCom receiver hardware or software (such as disabling device cameras in high security areas), providing another security layer as a result of knowing the device position, and using the LCom receiver position as a part of a larger process.

    Abstract: Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

    Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some cases, an LCom-enabled luminaire configured as described herein may acquire user data from a local computing device and relay it to a server that tracks and analyzes the data to assess statistics for the luminaire's local spatial environment. The disclosed luminaire may receive from a local computing device a request for indoor navigation to a target of interest, such as a remote computing device. The luminaire may relay that request to a downstream luminaire, which delivers the request to the target. The target may respond with data that allows for tracking of its location and indoor navigation thereto, regardless of whether that target is moving or stationary. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, for example, via an optical interface or other wired or wireless communication.

    Abstract: Techniques are disclosed for identifying and controlling light-based communication (LCom)-enabled luminaires. In some cases, the techniques include a luminaire communicating its ID to a computing device via one or more LCom signals. In some cases, a user may be able to aim a rear-facing camera of a smartphone at the luminaire desired to be controlled. Once the luminaire is in the field of view of the camera, the ID of the luminaire can be determined using one or more LCom signals received from the luminaire. The ID of the luminaire may be, for example, its internet protocol (IP) address or media access control (MAC) address or another unique identifier. Once a luminaire has been identified, commands can be issued to the luminaire to adjust one or more characteristics of the light output, such as changing the dimming percentage of the light output.

    Abstract: Techniques are disclosed for projecting visible cues to assist with light-based communication (LCom), the visible cues referred to herein as visual hotspots. The visual hotspots can be projected, for example, using a luminaire that may be LCom-enabled. The visual hotspots may be projected onto the floor of an area including an LCom system. The visual hotspots can be used for numerous benefits, including alerting a potential user that LCom is available, educating the user about LCom technology, and assisting the user in using the LCom signals available in the area. The visual hotspots may include images, symbols, cues, characters (e.g., letters, words, numbers, etc.), indicators, logos, or any other suitable content. In some cases, the visual hotspots may be interactive, such that a user can scan the hotspot to cause an action to occur (e.g., launch an application or website).
