Situation: I just entered the room and there is a projector on my right.
Alternative situations: I am standing in front of a wall in the bottom left corner of the room and all I can think of is I can't want to leave through the door in front of me in the next 5 minutes. I've just got into the room through the door behind me, there is a cabinet on my right side.
Question: What object to my right is the projector screen placed on top of?
