Historical storytelling technology
During the 80th anniversary of National Day, the technology project “Returning to the sacred moment” became the focus, not only as an exhibition event but also as an emotional journey. The technology door opened, bringing visitors back to the heroic atmosphere of September 2, 1945 to listen to Uncle Ho read the Declaration of Independence with the people of the whole country, witnessing the sacred moment of the birth of the nation.
When wearing virtual reality (VR) glasses, the experiencer seems to be immersed in a sea of people, waving red flags with yellow stars. The cheers mixed with the warm, emotional voice of President Ho Chi Minh : "Vietnam has the right to enjoy freedom and independence..." echoed. Every detail, from the loudspeaker, the golden autumn sunlight to the costumes of the people, were meticulously recreated. It was not just "watching" history but "reliving" the emotions of thousands of people who were together giving birth to a free nation. The attraction of this project far exceeded all expectations. Nearly 2,000 people directly experienced it on the opening day and after only 6 hours, nearly 30,000 online registrations were recorded. The touching images of old people wiping away tears, children cheering loudly or people lining up regardless of rain or shine proved one thing: technology when combined with history and patriotism will create extremely special values. Ms. Nguyen Ha Phuong and her mother shared after attending the emotional experience: “Hearing the oath in that space, I wanted to shout it out loud. So emotional!”
Behind this emotional experience is the hard work of a team for many months. The design research team worked closely with historians and cultural researchers to build a space that is both lively and accurate to every detail from costumes, hairstyles, to shoes and vehicles. Especially the technical solution for the software to operate smoothly when recreating the image of tens of thousands of people in the historic Ba Dinh Square... Many young people, especially students, also expressed their interest. This project is not only an experience but also an approach to history suitable for the new technological era.

VR and AR (augmented reality) technology was also applied for the first time at the Ho Chi Minh Relic Site in the Presidential Palace. Black and white photos and artifacts that seemed to be “sleeping” suddenly came to life. Just by swiping their phones, visitors can see Uncle Ho reading the Declaration of Independence or images of people attending the ceremony. Lieutenant Khuat Duy Long (Vietnam Peacekeeping Department) said: “AR simulated very realistically, I felt like I was standing in the middle of Ba Dinh Square that year.”
Inspiring today's generation
Many other exhibitions also show how technology changes the way history is told. At the 48 Hang Ngang relic, where Uncle Ho drafted the Declaration of Independence, a hologram (three-dimensional image) recreated the image of him at his writing desk, yellow light shining on his thoughtful face. 3D mapping projected the scene of Ba Dinh Square, recreating the heroic atmosphere. Visitors entering that space seemed to relive with Uncle Ho the moments of preparation for the important event. From this perspective, the exhibition at 48 Hang Ngang is no longer a purely display event but becomes a space where tradition and modernity intersect. The historical story is told by touching all the senses of the viewer, connecting the sacred past with the vibrant present.
The exhibition Keeping the Oath of Independence at the Vietnam Military History Museum on this occasion also used AR and sensor frames, helping more than 300 artifacts become moving footage. The students accompanying the tour group were excited, constantly raising their phones to “capture” the vivid moments.
In addition, the A80 application - Proud of Vietnam becomes a "digital assistant" accompanying the ceremony. On the digital map, users can look up the parade route, medical stations, toilets, restaurants, and nearest hotels. The application also allows creating electronic cards and "80 years" avatars to share the spirit of National Day on social networks. In just a few days, A80 has reached more than 1 million downloads, highly appreciated for its convenience and widespread meaning. On this occasion, the exhibition "Hanoi Flag Tower - Fatherland and the desire for peace" will also officially open from September 1 at the Hanoi Flag Tower space. The story of more than 200 years of history of the Flag Tower is recreated between original artifacts, maps, 3D models, documentaries and 3D mapping lighting art...
From holograms at 48 Hang Ngang, AR at the Ho Chi Minh relic site, VR in the project “Returning to sacred moments” to AI photo restoration, A80 application… technology has truly become a bridge connecting the past and the present. For the younger generation, history is no longer dry but becomes an intuitive, memorable, and emotional experience. For those who have been through war, technology is like a “time machine” that brings them back to emotional memories.
