Abstract
Techniques and architecture are disclosed for navigating an area with multi-panel luminaires configured to display fiducial patterns. In an embodiment, a system includes a plurality of luminaires located in an area and configured to display one or more fiducial patterns recognizable by a mobile computing device. The luminaire includes a plurality of panels, each panel associated with one or more solid-state light sources. The luminaire also includes at least one driver configured to control the light sources to transmit light through the plurality of panels at varying light intensities to display a fiducial pattern and configured to detect errors in the display of the fiducial pattern.
