Glad to see another video/post. Very informative. Thank you.

Hello, i'm trying to build the AR sandbox, i saw other videos recommanding the size of 30x40", i wonder if building it any bigger would cause issue with kinect detecting sand depth (surely by keeping the 3:4 ratio). thank you

You could build the sandbox at a wide range of sizes. The issue is the Kinect camera's limited resolution. The larger you make the box, the worse the software's internal representation of the sand surface is going to be. This especially holds for elevation measurements. If you make the box twice the size, meaning you have to put the camera at twice the height above the box to capture it all, elevation resolution will decrease by a factor of four. I recommend 40"x30" because it is a good compromise between play size and scanning resolution.
