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.
