Please consider that sufficient floor space/desk surface and lighting conditions are required, and the time for the scanning and detection process to map out the environment. This step by be achieved by slowly moving the mobile device in a circular motion, as indicated by the UI/UX elements. This procedure involves physical environment tracking and simultaneously, thus creating and placing as many point clouds (white dots) as possible to achieve a steady placement of the virtual elements in the surrounding environment.

SLAM Scanning and Detection Process

When a similar appearance of point clouds is displayed on your screen, as in the above image, tap on them to place the virtual elements at that location/position, which will blend with your environment.

Points to note:

• Navigate around the scene; clues can be lighting sources and virtual objects.
• Actions are triggered when you are near virtual elements.
• If you need any guidance, please ask your instructor.
• You can check your knowledge by completing the "About AR Development" quiz.
