I want to use Hololens2's spatial recognition to detect what I put on my desk.

What do you want to do

·If you have a mug, watch, or cell phone on your desk, attach a bounding box only to the watch as seen from Hololens 2.
·The bounding box is projected in real time, and the size changes depending on the size of the clock
·In addition, the bounding box will follow you even if you put the clock on your wrist.

Problems

"·I was able to recognize ""desk"" and ""floor"" using the ""space awareness"" function of Hololens, but
" 　"I think it is difficult to recognize small things like ""something"" (for example, a clock) on the desk."
·Experimentally, I skip Ray from Head and try to infer the shape of the object using collision determination with the spatial recognition layer.
　Space-aware mesh is rough (even high mesh) and can slip through or out of alignment.

If detailed recognition becomes possible, it is assumed that a bounding box can be attached to the target. Do you know any improvement measures or breakthrough measures?Also, I would appreciate it if you could let me know if you have any sample sources for reference.
