Degree Show plan

Here is the plan I want to show my project.
I wanted to use rear screen for the show however it is not only to find out but
make more complex unless I can use big space.

The things I need to figure out are.

Projector
There would be an interrution between viewer and projection If I put the projector under the chair. It is depends on whether my place is narrow enogh to hang a screen and a projector on each side.
But I think most of student would be the same situation and want the place like me. I may put a projector in middle of the chaire like arm.

Sound
I prefer to play sound directly to the view but it also need to be concerned the show's atmospere. playing music without using headphone would make noise and people even hardly hear the sound.
