1. A method, comprising: capturing image data with at least a camera of a painted surface display system; analyzing the image data to determine a real-world context proximate to a painted surface, wherein the painted surface is painted with a photo-active paint; determining electronic signage data based on the determined real-world context; generating a sign image from the determined electronic signage data based on the determined real-world context; and driving a spatial electromagnetic modulator to emit electromagnetic stimulation in the form of the sign image to cause the photo active paint to display the sign image on the painted surface, wherein capturing the image data includes capturing image data of both the sign image displayed on the painted surface and a user located adjacent to the painted surface, wherein analyzing the image data to determine the real-world context includes analyzing the user relative to the sign image currently displayed on the painted surface.
