Tech Notes
Have you ever pulled on a door handle expecting the door to open, only to find out you needed to push? Usually these doors are in a public space, have an ambiguous bar, and are never clear if you need to push or pull. If you are lucky, worn letters or braille of “Push” or “Pull” might be marked on the handle. After much struggle, everyone eventually sheepishly opens the door. People sometimes feel as if they should have remembered how the door opens, which is not the case.
