Situation: I am seated on a black chair at the table and facing a table with a projector screen behind me and there are two chairs on the same side of the table with me on my left.
Alternative situations: I turn around 180 degrees from the door and walk into the room, to the projector screen where I turn another 90 degrees to my left and take a seat in the chair. I am sitting on chair bottom right corner of the table, writing notes down on a notebook that is resting on the table in front of me.
Question: Which way can I see my backpack?
