What Is a Holobox? 21-Inch and 7 ft Explained

What is a holobox, in plain terms?

A holobox is a display cabinet built to show an AI avatar with a 3D-style effect, so the avatar appears to stand inside the box rather than sit flat on a screen.

It's the same AI avatar you'd find on a plain 2D screen — the difference is entirely in how it's presented. A holobox gives the avatar a sense of depth and presence that a flat screen doesn't, which is why people often reach for the word "hologram" to describe it, even though the avatar itself is identical either way. faceOS offers two sizes of holobox, each built for a different kind of space, which is the question most people actually mean when they ask "what is a holobox."

How does a holobox create the 3D-style effect?

In plain terms, a holobox is a display cabinet that makes the avatar appear to stand inside it, rather than showing a flat picture on a screen.

If you're comparing holoboxes, the more useful comparison is what each size is actually built for, covered in the two sections below.

The 21-inch holobox: what it's for

The 21-inch holobox is the compact format, built for counters, booths and reception desks where space is limited but you still want a 3D-style presence.

It suits a registration desk at an event, a product counter in a showroom, or a reception point in an office — anywhere a visitor approaches a fixed spot rather than walking past it. Because it's smaller, it's also quicker to set up and easier to fit into a tight floor plan, which makes it a practical choice when you're sharing floor space with other stands or furniture, such as on an exhibition booth or a shared lobby desk.

The 7 ft holobox: what it's for

The 7 ft holobox is the life-size format, built for entrances, stages and open floor areas where you want the avatar to be the first thing people notice.

It suits a mall atrium, an exhibition hall entrance, a stage at a conference, or anywhere with enough open space for a life-size presence to register from a distance. It's the format most people picture when they imagine a "hologram" greeting them as they walk in. Because it needs more floor space and a clear sightline, it's worth confirming your venue can accommodate it before you commit to a size, which is part of what we'll talk through with you when you enquire.

Holobox or 2D tabletop screen — the short version

If you don't need the 3D-style presence, a 2D tabletop screen does the same job on a flat display, and it's the simplest machine to place on a desk or counter.

It comes down to how much visual presence you want versus how simple the setup needs to be. A tabletop screen is the easiest option to fit into an existing desk or counter without changing the layout around it; a holobox asks for a bit more space and planning but gives the avatar noticeably more presence in return. If you want the full comparison, our guide to holobox vs 2D screen walks through the trade-offs between all three machines in depth.

Can I rent a holobox, or do I have to buy one?

You can rent a holobox for a single event, rent it long-term with a monthly avatar subscription, or buy it with a monthly avatar subscription.

Renting suits a one-off event or a short campaign; buying suits a permanent spot you expect to keep running for years. Our guide to holobox rental cost in the UAE breaks down event pricing from AED 3,500 per day.
