The door example: person feels trapped in the doors and begins to panic. Bad design, at brock u arranged by lettered block and people get lost due to the fact that they aren"t in alphabetical order people get lost, airplane is well designed. Human error: depends of the goal of the operator and the system, most errors are human errors, typically due to design. Errors of omission: basically forgot to do something example a step your forgot which leads to error, operator forgets to preform the activity. Incorrect action is preformed: timing error(too fast/slow), sequence errors( improper order), Quantitative/qualitative error( movement form: pushing a door when you are exposed to pull on, you do something you aren"t exposed to do. Interface is where the interaction happens between human and machine: human: information perception information processing- control, machine: input- processing /reaction, output. Redundancy gains: present a variable in more than one way will make it more likely to be.
