A system includes a photophoretic display device including a trap light source and an illumination light source, an image converter including a light signal propagation director and a light signal sensor, and a control unit. The trap light source is configured to trap a scattering particle and the illumination light source is configured to illuminate the scattering particle that the trap light source is configured to trap such that the photophoretic display device generates a volumetric image. The light signal propagation director is configured to direct a visual signal of the volumetric image to the light signal sensor. The light signal sensor is configured to sense the visual signal and to generate a planar image signal based on the visual signal. The control unit is configured to send the planar image signal, receive a user input signal in response to sending the planar image signal, and control one or more of the trap light source and the illumination light source to change the volumetric image based on the user input signal.
