## Abstract

A system for displaying, to viewers who do not need to wear special eyewear, static three dimensional (3D) images that are dynamically augmented with two dimensional (2D) images. The system includes a holographic print with a front surface and a back opaque layer. The system includes a projector projecting light onto the front surface. The projected light includes first light reconstructing a hologram from the front surface of the holographic print and second light displaying 2D content on the front surface. The projector is positioned to cause the first light to strike the front surface within a range of hologram reconstruction angles. The projector is a video projector, and the first light is even illumination in the form of white light while the second light includes the displayed 2D content. The displayed 2D content includes animation or video content.

## Claims

### Claim 1

A system for displaying to viewers static three dimensional (3D) images that are dynamically augmented with two dimensional (2D) images, comprising:
a reflection holographic print with a front surface; and
a projector projecting light onto the front surface,
wherein the projected light comprises first light reconstructing a hologram from the front surface of the reflection holographic print and second light displaying 2D content on the front surface,
wherein the projected light from the projector is configured to direct the first light onto a first region of the front surface and to direct the second light onto a second region of the front surface differing from the first region with no overlap of the first and second regions on the front surface,
wherein the first region of the front surface corresponds to areas of the reflection holographic print configured prior to the projector projecting the light to provide a rendition of the hologram, and
wherein the second region of the front surface corresponds to areas of the reflection holographic print free of holographically recorded content.

### Claim 2 (depends on 1)

The system of claim 1, wherein the reflection holographic print further includes an opaque back layer opposite the front surface.

### Claim 3 (depends on 1)

The system of claim 1, wherein the first light comprises even illumination.

### Claim 4 (depends on 3)

The system of claim 3, wherein the projector is positioned to cause the first light to strike the front surface at an angle within a range of hologram reconstruction angles for the reflection holographic print.

### Claim 5 (depends on 3)

The system of claim 3, wherein the projector is a color video projector and the first light consists substantially of white light.

### Claim 6 (depends on 5)

The system of claim 5, wherein the projector provides the first light at a brightness level that is less than 90 percent of a maximum brightness capacity for the projector.

### Claim 7 (depends on 1)

The system of claim 1, wherein the displayed 2D content includes animation or dynamic video content.

### Claim 8 (depends on 1)

The system of claim 1, further comprising one or more additional reflection holographic prints each with front surfaces and wherein the one or more additional reflection holographic prints and the reflection holographic print are positioned with the front surfaces spaced apart from each other and wherein the projected light reconstructs additional holograms from the front surfaces of the additional reflection holographic prints.

### Claim 9 (depends on 1)

The system of claim 1, further comprising a head tracking assembly tracking a viewer's position and wherein the system operates to provide at least one of simulated parallax or occlusion effects in the 2D content consistent with the hologram for a viewpoint associated with viewer's tracked position.
