Watch bad doors!
Bad doors are everywhere. Often it can become challenging how to open or use the door in it’s correct way. We all know these doors and start question ourself before we question the door. But, the good news is, it’s not you creating the problem, it’s in most facts the doors fault.
And not only doors can create those usability issues. See how Don Norman, a former Professor of psychology, Professor of cognitive science, Professor of computer science and Vice President of advanced technology at Apple describes the problem. He talks about the principals of Human-Centered-Design, the discoverability and feedback of many daily used things.
