3d representation of "my head"

I think this may already exist.  I just cant find it.      http://backyard-history.com/mbient.jpg

I would like to have my metawear  fob inside my wool cap,

and track my head orientation.  "SEE" where my nose is pointing.  

          I have in mind to have an azi-el camera (a foscam, because I have one and can control it) see where I am looking?

Thank you, Bradshaw at Buzzards Bay MA, doing underwater photography in the cold speedy Cape Cod Canal.
