An automatic door, also known as an auto door, is a door that opens automatically, without the need for human intervention or usually upon sensing the approach of a person. A person can be detected by microwave pulses, infrared sensors , or pressure-sensing pads.
To open the door, the motor turns the pulley, which in turn turns the belt, which in turn drags the door. To close the door, the reverse occurs. Historically, elevator doors were opened using simple harmonic motion by a set of mechanical linkages; the motor, geared down, would rotate linked arms, which in turn would drive the door.
Swing side, door mounted sensor—mounted on the swing side of the door itself, used as the door is opening to detect a user in the way of the opening door. In that case, the operator stops the door. The sensitivity of infrared sensors must be reduced at the end of the opening angle, if it starts seeing a wall next to the door, so it may not ...

A door is an example of a complex feature that is seemingly trivial to implement correctly. In the original description of the analogy, Liz England justifies and explains the job requirements of a designer and how complex the job actually is compared to how the requirements are initially posed (making a door).
