View the location name, opening hours, brief introduction, and featured AR activities/content.
Select Explore now to begin.
The first time you start an experience, the application displays a notice stating that children should be supervised by their parents when using AR. Select OK to continue or Skip to dismiss the notice.

Check your location before starting: If you are not at the correct location or have not granted location permission, the Explore now button may be disabled (for example, you are in Hanoi while selecting an AR location in Ho Chi Minh City).

4.2. Scanning and Recognizing the Space

Hold the phone upright and point the camera toward the surrounding area.
Move the phone slowly so the application can scan and recognize the space.
Point the camera toward areas with recognizable visual features.
Make sure the area has sufficient lighting.

Tips for better recognition: Keep the phone steady, avoid moving it too quickly, and avoid areas that are too dark or have too few recognizable features.

4.3. Displaying AR Content

After the space is successfully recognized, AR content appears on the screen and is positioned within the real-world environment.
Depending on the experience, the content may consist of static images/models, animated content, or interactive content.
During the experience, the screen provides the following controls:
- Exit: Exit the AR experience.
- Camera: Capture the current scene.

Tap the Navigation button (arrow icon) on the AR experience screen.
The application displays a list of destinations, rooms, or locations available in the area.

A series of 3D arrows appears in the real-world environment on the screen. Follow the direction of the arrows to reach the selected destination, while continuing to observe the screen as you move.
Tap the Map button to open the 2.5D map. You can zoom in/out or close the map to return to the AR navigation screen.

When navigation is no longer needed, tap Stop to stop AR navigation mode.

The content and interaction methods of these extended features are updated according to each project’s deployment requirements.

After the admin reviews and approves the project, it will no longer appear in My Library and will be made publicly available in the Xense AR application to other users according to the system’s public availability mechanism.
