ARium is an augmented reality application that allows users to create immersive scenes by placing objects in their surroundings. After selecting locations for four objects by tapping on yellow dots, the program generates fifty small occluding objects around them for a realistic experience. The app encourages users to explore the scene, suggesting an optimal distance of approximately 3 feet (1m) from the device for the best interaction.

One of the unique features of ARium is the ability to customize objects using photos from the device's Photo Library. Users can wrap "skinnable" and noise objects with their chosen images, enhancing the personalization of the augmented reality environment.
