SK Telecom announced that it, together with the Cultural Heritage Administration and Google, launched ‘Changdeok ARirang,’ an augmented reality (AR) service based on 5G edge cloud to provide an immersive experience for visitors of Changdeokgung Palace.
Changdeokgung Palace (or Changdeok Palace) was built in 1405 by King Taejong, the third ruler of Jo-seon. All palaces in Seoul were burnt down during the Japanese invasion in 1592 and Changdeokgung Palace became the first palace to be rebuilt in 1610. Since then, it became the primary palace for about 270 years where 13 kings including the last monarch dealt with state affairs. Changdeokgung Palace was designated as a UNESCO World Heritage Site in 1997 and is regarded as a masterpiece of Korean palace architecture where the buildings are in perfect harmony with the natural setting.
Upon activating the Changdeok ARirang app and holding their phones towards the palace, users will get a surprise welcome from Haechi, a mythical creature believed to guard the palace. Haechi, a virtual guide, will escort visitors throughout the palace, providing detailed information on 12 different tourist spots within the palace as well as interesting historical stories.
To make the visit more interactive and memorable, Changdeok ARirang offers diverse AR experiences to visitors, allowing them to watch a royal court dance performance, play Korean traditional games in AR and take AR pictures.
With Changdeok ARirang, visitors can also take a close look around restricted areas such as Huijeongdang and the palace's secret garden, Huwon, through 360-degree AR. For instance, upon reaching the entrance of Secret Garden, a restricted area, visitors will see an AR portal from which visitors can be transported to the beautiful Secret Garden.
5G Android smartphone users can download the Changdeok ARirang app from Google Play and One Store. The app supports both the Korean and English languages.
Changdeok ARirang is designed to deliver a true 5G-based AR experience to users by realizing ultra-low latency data communication. To this end, SK Telecom installed a total of 12 units of 5G base stations within Changdeokgung palace and built the service in the 5G edge cloud deployed at its Central Office in Seongsu-dong, Seoul. With 5G edge cloud, which enables data processing within the 5G infrastructure located closest to the end-user devices, visitors at Changdeokgung Palace can experience approximately 60 percent faster speed when downloading contents from the Changdeok ARirang app.
To recreate Changdeokgung Palace in AR, SK Telecom worked closely with Google and Nexus Studios, an animation and interactive studio based in the UK, and Seerslab, an augmented and virtual reality corporation in Korea. They built the AR experience based on Google Cloud, ARCore, Google’s AR platform, and other latest AR technologies including Lighting Estimation and Cloud Anchor.
With Google’s Cloud Anchor, which is used to enable digital information overlaid on top of the real work to be experienced by multiple users at any time, virtual Haechi can provide visitors with seamless guidance and immersive AR experiences throughout the tour. Lighting Estimation has been applied to create a sense of reality in AR by expressing hologram contents appear naturally depending on the level of lighting at the site.
