@nikitonsky if a new edition of The Design of Everyday Things is printed, this exact example should be included in the discussion of door handles and affordances

@nikitonsky for every automatic door automation can be disabled at least for maintenance and there you need a handle

@nikitonsky the handle is a safety feature for of the door breaks or electric is gone. So removing it will not be enough

Maybe if you make it handle you can push in or put it very low so you force of habit does not kick in

@nikitonsky no, removing the handle can't prevent people from forcing the door by pushing. What is really missing in most automatic doors is a clutch to disengage the support when a certain amount of force is applied.
