I wish to create a set of physical tokens, each with a unique design so that each token can be tracked. Think of printed squares with unique abstract images on each one. An AR virtual object would be connected to each token, so if the user moves the token, the AR image moves. Think of a fancy chessboard. What is a good method or tool to create the needed artwork? Each design should be unique, but need not be human identifiable. Similar projects for other devices use patterns of lines and dots, but other methods can be used. The important thing is a design that ARKit has no issues identifying and tracking each token. Does anyone have a suggestion?
Creating physical tokens for ARKit tracking
You may have a look at App Clip Codes. Here is a developer sample that illustrates their usage with ARKit.
An alternative could be image tracking. When loading a set of detection images, Xcode can warn you if some are too similar, which can help you create a set of unique images. While this technology is not ideal for minimal, abstract images, it might still work dependent on the design you have in mind, so it may be worth a try.
