There are more sophisticated protocols using them can manage multiple eyeglasses, each separately, it is made to replace splitskrin. So television can watch several persons, each of them will only see his picture on the entire screen.

Lord, I have everything. In the next section we will analyze a real 3D helmet. If you have any comments and advice I will gladly listen.

For special interest is the description of the protocols
