REB / recognizable elevator button


Nowadays buildings are taller and taller, so elevators have become part of our lives. Arrangement of buttons in the elevator is confusing and inefficient. It will take seconds, even a minute, to choose the right floor. In the new design, buttons’ placements are arranged by floor numbers, so people can find specific buttons quickly. It is more efficient.
