With iOS SDK, I am able to create AR apps that allow users to: 1/ Place objects on the floor/walls. 2/ Place objects on the body, not just behind it. I'm currently working on setting up objects behind the body as well. 3/ Create various types of face masks. 4/ Work with tags, whether they are objects or video hooks. In addition, with Unity SDK, I can create simple games such as car driving, object placement, face masks, and work with tags.
