AI summary

A method and apparatus for gesture interaction with a photo-active painted surface is described. The method may include driving a spatial electromagnetic modulator to emit electromagnetic stimulation in the form of an image to cause photo-active paint to display the image. The method may also include capturing, with at least a camera of a painted surface display system, image data of the image displayed on the photo-active paint applied to a surface and a user motion performed relative to the image. The method may also include analyzing the captured image data to determine a sequence of one or more physical movements of the user relative to the image displayed on the photo-active paint. The method may also include determining, based on the analysis, that the user motion is indicative of a gesture, and driving the spatial electromagnetic modulator to update.
