So it goes something like this then: Aunt Tilie wants to go outside so she goes to her desk and writes on a sheet of paper door open then presents it to the door which responds with a paper that says how do I know it is you aunt Tilie some one could have crawled in the window last night. To which she hands the door another sheet of paper with her password. Riiight. She approaches the door pannel and visually identifies the door's current state and manipulates objects on that panel until it is in the appropriate state then she can open the door.
