Techniques for selective viewing of projected images

An entertainment enhancement system, comprising:

• a display system comprising a display surface, wherein the display system is configured to display a visible light image on the display surface in a visible spectrum;
• an infrared projection system configured to output an infrared image to the display surface, wherein the infrared projection system comprises:
• a controller configured to generate instructions for projecting the infrared image in coordination with the visible light image based on input from the display system;
• and
• an infrared emitter configured to receive the generated instructions and emit the infrared image to the display surface in response to receiving the generated instructions, wherein the infrared emitter emits the infrared image at frequencies outside the visible spectrum and not at frequencies in the visible spectrum;
• and
• a viewing device configured to be wearable by a user, wherein the viewing device comprises:
• at least one lens;
• and
• a filter assembly configured to shift the infrared image from an infrared frequency outside the visible spectrum to a visible light frequency in the visible spectrum, wherein the shifted infrared image and the visible light image are viewable on the display surface through the at least one lens.

A method, comprising:

• generating instructions for projection of an image based at least in part on an input;
• emitting light at one or more frequencies outside of a visible range to form the image on a target surface based at least in part on the generated instructions, wherein the image comprises a message for at least one viewer of the image;
• and
• providing a viewing device having at least one lens to the at least one viewer, wherein a filter assembly of the viewing device is configured to shift the image from the one or more frequencies outside of the visible range to one or more visible light frequencies such that the image is viewable on the target surface through the at least one lens via the filter assembly of the viewing device.
