Arrow by jinhyuk rho from korea

we've always been confused by door handles, especially those outside of buildings.
there is no sign showing us the right direction to push or pull.
more often than we would like, we open the door in the wrong direction.
opening by pushing the door when in fact one has to pull can cause injury to people
standing behind the door and disturbs the flow of people using the door.
this arrow door handle makes up for this weakness.
the user knows which way he should open the door by noticing the direction of the arrow-like door handle.
