I wrote about door design a few years ago and listed two similar examples:
- a swinging door with a handle on one and a plate on the other side
- a swinging door with handles on both side (wrongly) suggesting the door needs to be pulled on both sides (although someone tried to mend this mistake with a plate Push above both handles; otherwise, why would one side of the door need a manual and the other not?)
Here’s another nice design from an elementary school. I asked a child to open the door from both sides. Note the different handles and how a child (125 cm tall) interprets them. Note also the heigh at where they are positioned (chest height vs. over head height). However, while observing adults they often get confused with the pulling one (trying to push the handle at below the chest height).
