A free virtual reality exhibit in Nha Trang puts visitors inside Ba Đình Square on September 2, 1945, the morning President Hồ Chí Minh read the Declaration of Independence. VOV reported that the program, titled Return to the Sacred Moment (Trở về thời khắc thiêng liêng), runs October 24 to 26, 2026 at Quảng trường 2/4 in Nha Trang ward, Khánh Hòa province. Today, October 25, is day two of three.
The pitch is simple. Instead of reading about the founding of the Democratic Republic of Vietnam, residents and visitors put on a VR headset and watch it unfold in a 360-degree recreation built from 3D graphics, historical imagery, documentary footage, archival audio and sound effects. Entry is free. That combination of civic history and consumer hardware makes this a useful case study for anyone tracking how immersive technology moves out of gaming rooms and into public squares.
This analysis covers what the reports confirm, what they leave out, and what the hardware and content choices behind a public VR booth tell us about the wider market. Head-worn displays have made headlines for odder reasons this month, as our piece on the AI glasses chess cheating video showed, but the Nha Trang event is a far more conventional use of the form factor, and arguably a more durable one.

What Visitors Actually Do at Quảng trường 2/4
According to the Báo Khánh Hòa photo report, the program has arrived in Nha Trang and is set up at the 2/4 Square. Visitors queue, receive a headset, and step into a recreated version of the Ba Đình ceremony. The session is a guided playback, not a game. There is no scoring, no branching story and no controller input described in any report available today.
What the user sees is a historical moment rebuilt as a space. Reports describe a 360-degree environment with several viewing angles, so a visitor can turn their head toward the stage, the crowd or the surrounding square. The Declaration of Independence plays as archival audio, with sound effects layered under it. Documentary footage and historical imagery sit inside the 3D scene rather than on a flat screen.
Access matters as much as content. The program is free and open to both local residents and tourists, which removes the usual price barrier for a VR experience. In a coastal city that draws a steady flow of visitors, a free three-day installation in a public square can reach people who would never book a museum slot. The reports do not give a visitor count, so any claim about turnout would be a guess.
Confirmed Facts and Open Questions
Before going further, it helps to separate what is documented from what is not. The table below lists every detail available in reports from VOV, VTV, Báo Khánh Hòa and the Khánh Hòa provincial portal at the time of writing, along with the gaps.
| Item | Status | Detail from reports |
|---|---|---|
| Program name | Confirmed | Return to the Sacred Moment (Trở về thời khắc thiêng liêng) |

The unconfirmed rows are the interesting ones for a hardware audience. Without a headset model, we cannot say whether the booth runs standalone devices or PC-tethered units, what resolution visitors see, or how many people can go through per hour. We flag those gaps rather than fill them.
How the Ba Đình Recreation Works
The VTV report framed the program as a way for Khánh Hòa residents to return to the sacred moment of 1945 through VR. The technical recipe behind that framing is a familiar one in immersive media. A production team builds or captures a scene, layers audio, and delivers it through a head-mounted display that tracks the viewer’s head rotation.
Two content techniques are usually involved in heritage VR. The first is a fully modeled 3D environment, where artists rebuild a place from photographs and plans. The second is 360-degree video, where cameras capture a real scene. Reports on this program mention both 3D graphics and documentary footage, which suggests a hybrid, though no outlet breaks down which scenes use which method.
Audio carries a lot of the emotional weight here. The Declaration was spoken to a crowd in 1945, and the reports say the experience uses archival audio plus sound effects. In a headset, spatial sound can place the crowd’s murmur behind the viewer and the speaker’s voice ahead of them. That kind of staging is cheap to ship compared with photorealistic rendering, and it often does more to sell presence than extra polygons.
The Hardware Behind a Public VR Booth
No report names the headset, so what follows is analysis of how pop-up installations in general tend to work, not a description of this one. Public VR demands different trade-offs than home use. Devices must start fast, survive hundreds of strangers, and be cleaned between sessions. A headset that is wonderful on a desk can be a headache in a square with crowds, sun and a three-day schedule.
Standalone versus tethered headsets
Standalone headsets carry their own processor and battery, so operators can deploy a row of them with little cabling. Tethered headsets lean on a PC with a discrete GPU, which can push richer 3D scenes but multiplies the cables, the power draw and the points of failure. For a short, linear historical clip, the lighter option usually wins. For a heavily modeled square full of animated crowds, a PC-class GPU becomes more attractive. Our look at how handheld PC prices tier by power shows how steeply cost climbs once graphics headroom is the goal.
Storage and content delivery
Archival footage and 3D assets are large files, and a public booth cannot afford a buffering spinner. Most operators load content locally rather than streaming over a congested event network. That is why fast external drives matter for the production team that moves the same build between cities. Our comparison of portable NVMe SSDs covers the kind of storage that suits this job.
Comfort and throughput
Sessions for first-time users are typically kept short because unfamiliar viewers can feel motion discomfort, especially if the virtual camera moves. A seated or standing-still viewpoint with head-only rotation, which fits a ceremony at a fixed stage, is gentler than a walking tour. Short sessions also raise throughput, which matters when a free event draws a line.
Why Mixing 3D Graphics and Archival Footage Is Hard
Combining modeled scenes with documentary material sounds easy and is not. Archival film from the 1940s is low resolution, often monochrome and framed for a flat screen. A modern headset renders at far higher fidelity, so any old footage dropped into a 3D scene can look jarring next to crisp polygons. Producers usually solve this by placing the footage on a virtual screen inside the scene or by using it as a transition between rendered sequences.
Display quality also shapes the result. Headsets use small panels viewed through lenses, so contrast, brightness and screen-door effects all influence how convincing a recreated crowd feels. Viewers who care about panel technology may find our guide to OLED burn-in prevention a useful companion, since public kiosks and always-on displays face the same wear questions.
The final challenge is accuracy. A recreation of a real event invites questions about who stood where, what the weather looked like and which details are artistic license. The reports say the content draws on historical imagery and footage, which is a good sign, but none of them describe a historical review process. For a subject this significant to the public, that review is worth publishing.
Historical Context: September 2, 1945
The event at the center of the experience is one of the best-known moments in modern Vietnamese history. On September 2, 1945, President Hồ Chí Minh read the Declaration of Independence at Ba Đình Square in Hanoi, announcing the establishment of the Democratic Republic of Vietnam. The date is still observed as National Day. Eighty-one years later, the speech remains a fixture of school curricula and public commemorations.
Bringing that moment to Nha Trang, far from the capital, is a deliberate act of access. Most Vietnamese citizens were not in Ba Đình in 1945, and most cannot easily visit Hanoi’s historic sites on demand. A traveling VR installation shrinks that distance to the length of a queue. The reports describe this as a way for ordinary people to feel present at the founding moment, which is an emotional framing as much as a technical one.
Technology has long been used to carry such moments to wider audiences, from newsreels and radio rebroadcasts to televised ceremonies. VR is the latest step in that chain. What changes is the position of the viewer, who moves from watching a crowd to standing inside one. Whether that makes the history stick better is an open research question, and the reports offer no learning data from the Nha Trang run.
Market Impact: Immersive Tech Moves Into Heritage
Government and media-backed VR showcases do not move stock prices, but they do shape demand for headsets, content studios and event production services. A free public installation gives local audiences their first hands-on VR session, and first sessions often decide whether a person later buys a device or signs up for a school VR program. In that sense, a three-day booth works as an unusually effective product demo.
The commercial opportunity sits mostly with content producers and integrators rather than headset makers. Each heritage project needs scripts, 3D artists, sound designers and historians. Once a build exists, it can travel, which spreads the fixed cost over many venues. That economics favors studios that can package a single title for repeated deployment, a pattern common in touring exhibitions.
For consumer hardware, the signal is quieter. Events like this normalize head-mounted displays for people outside the gaming audience. Meanwhile, phone makers are chasing larger screens as another route to immersive viewing, as our report on Netflix clips on the iPhone Duo’s 7.6-inch display shows. The two paths compete for the same attention, and heritage content could end up on both.
Industry Data on Immersive Technology
Because the Nha Trang reports contain no named on-record quotes, we turned to published industry research for wider context. These are older forecasts and taxonomies, not figures about this event, so read them as background on where analysts expect immersive tech to go.
PwC, in a 2020 study titled Seeing is Believing, projected that “Virtual reality and augmented reality could contribute $1.5 trillion to the global economy by 2030.” That is a forecast made six years ago, and it should be treated as a scenario rather than a measured result.
On the education side, a PwC study into the effectiveness of VR for soft skills training estimated that “VR training is estimated to contribute $294 billion to the global economy by 2030.” Training is a different use case from heritage, but both rely on the same idea that presence improves retention.
More recent is IDC’s 2024 spending guide taxonomy. IDC stated that “The 2024 IDC augmented-reality and virtual-reality taxonomy identified 127 named use cases, a 78% increase from the previous 71 use cases.” The jump shows how many new applications analysts now track, and cultural heritage experiences like the Nha Trang program fit squarely in that widening list.
Competitive Comparison: VR Versus Other Ways to Show History
Organizers had other options for marking the same event. A documentary screening, a projected 360 video, a smartphone viewer or a fixed museum diorama could each deliver the story. The table compares those formats on general characteristics, not on measured data from this program.
| Format | Immersion | Visitors served at once | Hardware load | Best fit |
|---|---|---|---|---|
| VR headset with 3D scene | Highest, viewer stands inside the scene | One per headset | Headsets, cleaning supplies, staff | Short guided experiences |
| 360-degree video on a headset | High, but fixed camera position | One per headset | Headsets, local storage | Real filmed locations |
| Phone-based 360 viewer | Medium, small screen | Many, on personal devices | Low, uses visitors’ phones | Wide reach, low cost |
| Projected dome or wall | Medium to high, shared | Many at once | Projectors, structure, power | Group viewing |
| Documentary screening | Low, passive | Large audience | Screen, speakers | Context and narration |
VR wins on presence and loses on throughput. Only one person sees the scene per headset, which is why public installations queue. A projected format reaches more people per hour but loses the feeling of standing in Ba Đình. By choosing headsets, the organizers appear to have prioritized emotional impact over raw audience size, a sensible call for a three-day event with free entry and a strong commemorative theme.
Risks and Limits of Immersive History
Immersive recreations carry real limits. The first is authenticity. When a scene is rebuilt in 3D, the viewer may mistake artistic reconstruction for documented fact. Clear labeling of what is archival and what is modeled helps, and the best heritage projects state that openly.
The second is accessibility. Headsets can be difficult for people with certain vision conditions, balance issues or mobility limits, and not every visitor is comfortable wearing one. A good public installation offers an alternative, such as a mirrored screen that shows what the headset wearer sees. Reports do not say whether the Nha Trang booth includes one.
The third is hygiene and logistics. Shared headsets need cleaning between users, and staff must fit straps, explain controls and keep the line moving. These operational costs rarely make the press release, yet they decide whether a free event feels smooth or chaotic. Finally, there is the question of evidence. No report cites survey data, dwell times or learning outcomes, so the impact claims remain qualitative for now.
Predictions: What Comes Next
These are our own analytical expectations, not reported plans.
- More local stops are likely. Free, short-run installations are cheap to repeat once a build exists, so expect similar events in other provinces if audience response is strong.
- Attendance figures should surface after October 26. Organizers of free public events usually publish turnout numbers once they close, and those numbers will be the first hard evidence of reach.
- Standalone headsets will stay the default for pop-ups. Fewer cables and faster setup suit short touring schedules, even if tethered rigs look better.
- Hybrid delivery will grow. A phone or web 360 version of the same content is a logical follow-up for people who miss the queue.
- Authenticity labeling will become a norm. As recreations multiply, audiences and educators will expect clear notes on which elements are archival and which are reconstructed.
How to Visit and What to Expect
The practical details are short. The program runs through October 26, 2026 at Quảng trường 2/4 in Nha Trang ward, and admission is free, according to the Khánh Hòa provincial portal. Opening hours and queue rules have not appeared in the reports we reviewed, so check local announcements before traveling.
Visitors should expect a line, particularly on the final day, and a short session once at the front. The experience is passive, so no gaming skill is needed. Anyone prone to motion discomfort can ask staff about seated options. English-language coverage of the program has appeared on Vietnam.vn, which carries a translated headline about residents reliving the sacred moments of 1945 through VR.
The takeaway: the Nha Trang event is a modest but telling deployment. It shows how a few well-chosen ingredients, namely headsets, 3D graphics, archival audio and a free public square, can turn a textbook moment into something people queue for. The missing details on vendor, hardware and budget are the next things worth watching.
