Realfiction's Dreamoc case is angled glass, not a hologram

What you see

A Dreamoc unit sits on a retail counter as a tall glass-fronted case, and inside it a bright video plays that appears to hover in front of, or blend into, a real product placed in the case at the same time. Realfiction's own 2011 product page describes "a dazzling combination of holographic-like, free floating video images, with a display of the physical product," aimed at retail brands wanting shelf-stopping visual impact. The phrase holographic-like is the company's own hedge, not a claim to true holography.

How it works

Realfiction's pages do not spell out the optics in one technical paragraph, but the documented details point to an angled-glass illusion in the Pepper's ghost family rather than any volumetric or interference technique. A 2014 features page for the Dreamoc HD3 instructs users to "open the backdoor and get easy access to operate the Dreamoc or place an object inside the display," and separately lists "angles" as a specification category, language consistent with a case built around a partially reflective angled screen that overlays a bright video image onto a real object sitting inside the housing, the same basic principle used in stage Pepper's ghost effects, scaled into a self-contained retail unit with an internal video player.

Viewing conditions and limits

The 2011 product page lists specifications for the standard Dreamoc: roughly 515 by 410 by 1620 millimeters, 1680-by-1050 video resolution, and 60 watts of power draw, figures describing a display meant to be viewed from in front, within a limited horizontal angle, in the moderate ambient light of a shop floor, bright enough to compete with store lighting but not built for direct sun. None of the retrieved pages states a maximum viewing angle, a real gap in the archived record.

What it is not

Realfiction's own case-study page calls the Dreamoc "the holographic 3D display," marketing language the company's more technical pages do not fully back: nothing in the archived material describes recording or reconstructing a three-dimensional wavefront, and the image is fixed to a single flat plane inside the case rather than occupying measurable depth the way a volumetric display does. It is not a true free-space hologram or a volumetric display; it is a video-and-glass illusion box, a close relative of the stage Pepper's ghost effect built for point-of-sale marketing.

• Does the case use a single angled pane or a more complex optical stack, beyond what the marketing copy states?
• What is the actual usable viewing angle before the illusion breaks down or the reflected video becomes visible as a reflection?
• Is the physical object inside the case lit separately from the video content, and how are the two kept in registration?

The Dreamoc is a good test case for the word holographic in retail marketing: a commercially successful product line, described in the company's own words as holographic-like, while its detailed pages describe placing a physical object behind angled glass. Reading the plain specification language next to the marketing copy is the fastest way to tell which claim is which.
