Hey guys, I'm pretty new to AR, and not the most tech savvy so I apologize if some of these questions are ridiculous or outright stupid, but anyway..

I've seen AR be attached to a physical object like business cards and what not. And it seems to work much better when the image is being attached to a singular physical object like a QR code and not just "projected" onto a opened view in a room.

My question is, would this work for larger objects too? For example, if i wanted to attach a AR image to a t-shirt, would the t-shirt just need a QR code on it for the AR to attach to? And if so would the AR still work as that person walked or ran around or would it be lagging behind the person?

Would the projection only work at a certain distance away? Or is it completely independent on the camera being able to read the QR code and as long as it can read it it will be able to project the AR image?

And lastly, not sure if the technology is there but i've seen apps like AR kicks that just attach to your feet. Could the same be said for larger and further away object like a specific shirt? Or jacket maybe? I'm just curious on the current capabilities of AR and what factors are in play.

Thanks for any responses or reads everyone I appreciate the insight.
