The minimum horizonal movement is 2x in the same direction for the user to feel he has moved in that direction.
The movement is one tile distance away from the side walls , so that the user do not encounter a blank wall that causes disorientation. This holds true with the exception of the back wall. The back wall has indentation features.
Design of Experiment 02
Vertical movement is best viewed near to a featured wall or window , for the user to see that he is moving up or down .
A voice signal or command before the movement enhances the movement.
Improvements Done
Warning text is separated into 3 parts in sync with voice reading.
