Why Your Brain Pays Attention to Holograms: The Science Behind the Illusion
New neuroscience research is revealing why holographic displays can command attention, create deeper immersion and change the way people experience digital content. The explanation begins with how the human brain interprets reality.
Imagine walking through a busy shopping centre. You pass dozens of advertisements, digital screens, shop windows and promotional displays. Most barely register. Your eyes see them, but your attention has already moved elsewhere.
Then something unusual happens. A life-sized person appears to be standing inside a glass enclosure. They move naturally, turn towards you and seem to occupy a physical space, despite not actually being there. You slow down. Perhaps you stop completely. You know it is technology, but something about the experience demands a second look.
Why?
The obvious explanation is novelty. Holograms are unusual, and people naturally notice unfamiliar things. But recent scientific research suggests there may be more happening beneath the surface.
Studies involving brain activity, visual perception, attention and human behaviour are beginning to reveal why holographic experiences can feel fundamentally different from conventional digital imagery.
And the findings could have significant implications for the future of advertising, retail, entertainment and human interaction with artificial intelligence.
The science is beginning to catch up with the spectacle
In August 2026, researchers from Heriot-Watt University, the University of Liverpool and the Beijing Institute of Graphic Communication published a peer-reviewed study in Humanities and Social Sciences Communications investigating how people responded to holographic museum exhibits.
The experiment involved 91 participants in a controlled museum-like environment, comparing holographic presentation with more traditional ways of displaying cultural artefacts.
The results were striking.
- 95% preferred holographic displays to photographs.
- 56% preferred holographic displays to physical artefacts.
- 85% reported increased interest in museum collections.
The researchers also found a significant relationship between interactivity, visual appeal and satisfaction.
The distinction between these findings matters. Preferring a hologram over a photograph suggests that the format itself can influence how people experience information. Preferring it over a real physical object is arguably even more intriguing, although the smaller majority demonstrates that physical authenticity still matters.
The researchers were careful not to suggest that holograms are universally superior. The study measured preferences and reported experiences in a specific experimental setting, not commercial advertising performance or long-term behaviour.
Nevertheless, the findings raise an important question: what is happening in our perception when something digital appears to possess physical presence?
Researchers have now measured the brain's response
Just eleven days later, on 25 August 2026, the same research group published another paper, this time in npj Heritage Science.
Rather than relying entirely on participants describing their experiences, the researchers used electroencephalography, or EEG, to examine electrical activity in the brain.
Twenty-four adults aged between 18 and 55 viewed three types of museum presentations: holograms, photographs and three-dimensional printed artefacts.
The researchers monitored patterns of neural activity while participants viewed the exhibits and combined those measurements with questionnaires assessing perceived immersion.
The results revealed measurable differences.
Holographic displays were associated with lower activity in the delta and alpha frequency bands and higher theta activity relative to the other formats. Participants also reported significantly greater immersion when viewing holograms than when viewing photographs or 3D-printed models.
For anyone unfamiliar with EEG research, these frequency bands describe different patterns of electrical activity across the brain. Their interpretation depends heavily on the experimental conditions, and no single frequency can reliably identify one psychological state.
The study therefore does not prove that holograms automatically make people more attentive. The authors explicitly caution against treating the findings as causal evidence.
What it does demonstrate is that changing the way an object is presented can coincide with measurable changes in neural activity and subjective experience.
That is an important development. For years, the effectiveness of holographic experiences has largely been discussed through visual impact and anecdotal audience reactions. Research is now beginning to investigate those reactions through experimental neuroscience.
These two studies also come from the same research team, so they should be regarded as complementary findings rather than independent replication.
Your brain does not simply see images. It constructs reality.
To understand why holograms might produce these responses, we need to understand something extraordinary about human vision.
The human brain does not receive a complete three-dimensional representation of the world.
Instead, each retina receives a two-dimensional projection of light. The brain then processes multiple sources of information to reconstruct the depth, dimensions, movement and relative positions of everything around us.
It performs this process continuously, rapidly and largely without our conscious awareness.
Research published in the Annual Review of Vision Science explains how different regions of the visual cortex contribute to interpreting three-dimensional structure and combining depth information.
Among the signals our visual system uses are perspective, shading, occlusion, relative size, binocular disparity and motion parallax.
This is why a skilled artist can create the illusion of depth on a completely flat canvas. It is why filmmakers can make computer-generated characters feel believable, and why certain optical illusions remain convincing even when we understand exactly how they work.
Holographic displays take advantage of some of these same perceptual mechanisms.
Depending on the underlying technology, they can combine apparent depth, carefully controlled lighting, shadows, reflections, scale and movement to create the impression that digital content occupies physical space.
Not every commercial holographic display produces true optical holography or the complete set of depth cues available from a real object. Many use sophisticated visual illusions that create a strong impression of spatial presence from particular viewing positions.
Yet this distinction does not make the experience psychologically irrelevant. Our brains routinely construct convincing impressions of depth from incomplete visual information.
The critical question is not simply whether an image is three-dimensional. It is whether the visual information is convincing enough for the viewer to experience it as something occupying space.
That distinction sits at the heart of effective holographic design.
Why movement, shadows and reflections matter so much
Consider a digital human standing inside a holographic display.
Their clothing looks realistic. Their face is detailed. Their movements are natural. But beneath their feet there is no shadow, their shoes do not appear connected to the floor, and their proportions change strangely as they turn.
Something feels wrong.
The viewer may not immediately understand what causes this discomfort, but the visual scene contains conflicting information.
Now imagine the same digital character with realistic lighting, natural proportions, convincing reflections and carefully designed contact shadows. Their movements become grounded within the environment rather than appearing to float independently of it.
The difference is not merely artistic.
Vision science shows that the brain combines different depth signals when interpreting physical environments. A 2026 review in Annual Review of Vision Science examines how binocular disparity and motion parallax contribute to perceived depth, including how mismatched cues can affect immersive displays.
These findings help explain why the illusion created by holographic technology depends on far more than screen resolution or brightness.
At Miirage, this is central to how we approach holographic content. The objective is not simply to display a digital person or object in extraordinary detail. It is to make every visual element work together so the scene feels coherent.
When the illusion is convincing, attention can shift away from the technology and towards the person, product or experience being presented.
That is the real value of holographic presence.
Attention is only the beginning. What about memory?
Capturing somebody's attention is valuable, but it represents only the first stage of communication.
A person can notice an advertisement without understanding it, and understand an advertisement without remembering it.
The more interesting question is whether richer three-dimensional presentation can also affect how information is processed and retained.
A randomised study published in Medical Education in 2018 offers useful evidence.
Researchers assigned 179 nursing students to one of three groups studying cardiac anatomy. Participants used either autostereoscopic holograms, interactive 3D PDF visualisations or conventional printed two-dimensional images.
After studying the material, participants completed a knowledge assessment and reported their mental effort.
The median post-test scores were:
- 80.0 for students using holograms.
- 66.7 for students using 3D PDF visualisations.
- 66.7 for students using printed images.
The differences between the hologram group and both comparison groups were statistically significant, with p-values of 0.008 and 0.007 respectively.
The researchers also measured cognitive load on a scale from 1 to 20. Participants using holograms reported an average mental-effort score of 4.9, compared with 7.5 for those studying printed images. The 3D PDF group also averaged 4.9.
These results are particularly interesting because they suggest that richer visual presentation can, in some circumstances, help people understand complex spatial information without increasing perceived mental effort.
However, this was an educational experiment involving anatomy, not a test of advertising recall. It would be inappropriate to translate the result directly into claims about brand recognition or retail sales.
The broader principle remains relevant: the format in which information is presented can influence how effectively people learn from it.
For brands, museums and public information services, that makes holographic communication an important area for further investigation.
Why unusual things attract us, and why novelty alone is not enough
There is another psychological force at work: novelty.
Research published in Vision Research in 2020 examined how unfamiliar visual stimuli compete with visually prominent objects for our attention.
The researchers found that novelty can influence where people look, alongside established visual properties such as salience.
This is relevant to holographic displays because the format can introduce something visually unexpected into an otherwise familiar environment.
A shopping centre is full of rectangular screens. People understand them immediately. They know what a digital billboard looks like and have learned that most of its content does not require their immediate attention.
A human figure apparently occupying space inside a display challenges that familiar pattern.
But novelty creates a problem for any technology company hoping to build something permanent.
The brain adapts.
Studies of habituation in visual attention show that repeatedly encountering the same attention-grabbing stimulus can reduce its ability to capture attention over time.
In other words, simply being unusual is not a sustainable strategy.
A hologram that attracts attention today may become ordinary tomorrow if audiences repeatedly encounter identical content.
This is why the future of holographic technology cannot depend entirely on spectacle. Content needs to change, remain relevant and reward the attention it receives.
A holographic display showing an impressive visual illusion can attract an audience. A holographic experience that offers useful information, meaningful entertainment or a responsive conversation has the opportunity to do something more.
It can give people a reason to stay.
The difference between looking and engaging
One of the most interesting aspects of attention research is how much the environment influences viewing behaviour.
In a 2017 observational study published in i-Perception, researcher Claus-Christian Carbon observed 225 museum visitors viewing paintings.
The average time spent looking at an artwork was 32.9 seconds. When researchers included return visits to paintings, the average accumulated viewing time rose to 50.5 seconds.
These figures are not benchmarks for holographic advertising. They come from an art exhibition, where visitors have deliberately chosen to spend time viewing exhibits.
Nevertheless, they demonstrate that attention is more complex than a single glance.
People approach objects, change their viewing distance, return for another look and spend different amounts of time exploring what interests them.
This is an important consideration when evaluating holographic installations.
Counting how many people pass a display is useful, but it tells us little about what happens next.
How many people notice it? How many turn towards it? How many stop? How long do they look? Do they approach? Do they interact? Can they remember what they experienced?
These are different behaviours, and each one provides a different measurement of effectiveness.
For holographic advertising and retail media, moving beyond estimated impressions towards observable engagement could become one of the industry's most valuable opportunities.
The next frontier: when holograms look back at us
Human beings are particularly sensitive to faces, movement and social signals.
In research published in Frontiers in Psychology, researchers used eye tracking to investigate attention towards digital advertisements containing human faces.
They found that advertisements featuring animated faces attracted longer viewing than static versions under the conditions tested. When a face directed its gaze towards an advertised product, viewers were more likely to look at that product.
These experiments were conducted with conventional digital advertising, not holographic displays. Nevertheless, they reveal the importance of social cues in directing attention.
Now consider what happens when these principles are brought into the physical world through a life-sized holographic AI avatar.
Instead of displaying an advertisement that someone passively watches, the system can respond to questions, provide directions, explain products or offer assistance through natural conversation.
The experience moves beyond visual presentation into interaction.
A holographic AI assistant in an airport might guide a passenger towards their gate. In a shopping centre, it could help someone locate a particular retailer. In a museum, it could explain an exhibit or answer a visitor's questions.
In each case, the holographic appearance may create the initial attraction, but the usefulness of the interaction becomes the reason to remain engaged.
This distinction is critical.
The commercial future of holographic AI is not simply about creating ever more realistic digital humans. It is about combining visual presence with intelligence, relevance and genuinely useful experiences.
Does the science prove holograms are better than ordinary screens?
Not yet, and that is an important distinction.
While several studies have reported promising results for holographic presentation, the evidence is not uniformly positive across every outcome.
A September 2026 randomised controlled trial published in BMC Medical Education compared holographic 3D visualisation with conventional 2D photographic instruction among 60 dental students.
Both groups improved significantly, but the researchers found no statistically significant difference in their immediate practical preparation quality.
Interestingly, 70% of participants supported integrating holographic visualisation into future dental education, despite the absence of a measurable performance advantage in the primary comparison.
This highlights a crucial distinction between preferring a technology, feeling more immersed in it and demonstrating better objective outcomes.
A visually engaging format can improve the experience without necessarily improving every aspect of performance.
It also reinforces why different types of holographic technology should not be treated as interchangeable. A head-mounted augmented reality system, an autostereoscopic display and a full-body holographic display enclosure can offer very different visual and practical experiences.
For businesses evaluating holographic displays, the right question is therefore not whether holograms are universally better.
It is whether a particular holographic experience achieves a measurable improvement for the audience and application concerned.
That is a far more useful benchmark.
What this means for the future of advertising and human interaction
The traditional advertising industry has spent decades competing for attention through larger formats, brighter screens, more prominent placements and increasingly sophisticated audience targeting.
But there may be another way to think about the problem.
Rather than asking how to make advertising more visible, perhaps we should be asking how to make it more meaningful to the human brain.
Holographic technology offers a fascinating possibility because it changes the relationship between digital content and physical space.
An ordinary screen typically presents something to be watched. A well-executed holographic experience can make content appear to inhabit the same environment as the audience.
That difference opens up new opportunities for product demonstrations, storytelling, education and communication.
It becomes especially interesting when artificial intelligence is added.
A digital character no longer needs to follow a predetermined sequence. It can respond to the individual, adapt its information and participate in an exchange.
For Miirage, this is where holographic displays and AI converge.
The goal is not simply to create images that attract attention. It is to create intelligent experiences that use that attention productively.
The scientific research is still developing, and substantially more independent field testing is needed to establish how holographic displays perform across advertising effectiveness, long-term retention, purchasing behaviour and other commercial measures.
But the early evidence is already revealing something important.
How information appears in the physical world can influence how people experience it.
The most powerful hologram is the one you stop thinking about
Perhaps the most interesting thing about the science of holograms is that it ultimately has very little to do with technology itself.
Our brains evolved to interpret physical environments, recognise faces, identify movement and understand the spaces around us. Digital experiences are increasingly finding ways to communicate using those familiar perceptual signals.
The challenge for holographic companies is to make those signals as coherent and convincing as possible.
When a hologram feels artificial, the viewer notices the trick. When it feels believable, they can begin paying attention to the content rather than the mechanism producing it.
That is why the quality of the illusion matters. And it is why realistic movement, scale, lighting, shadows, reflections and physical depth deserve as much attention as resolution and hardware specifications.
We are entering a period in which holographic experiences will increasingly combine with conversational artificial intelligence, creating new forms of interaction between people and digital systems.
The screens themselves may become more sophisticated, but the biggest advances may come from a better understanding of the human brain.
Because the ultimate achievement of a hologram is not making someone marvel at the technology.
It is making someone forget about the technology long enough to experience what is standing in front of them.
And that may be the most compelling reason our brains pay attention to holograms in the first place.
The most powerful hologram is the one that makes you forget about the technology.
