Errors are part of any design. It's not a flaw in your creativity just a flaw in the way in which you've designed. Work with it and rectify it. Problem solve before problems arise.
Ergonomics is an applied science that coordinates the design of devices, systems, and physical working conditions with the capacities and requirements of the worker.
Anthropometrics is a comparative study of human body measurements and properties.
Usability is the ease of use and learnability of human-made objects

Push/Pull systems are very prominent. But they can have flaws too. Weight, strength needed to use them for example. Like the door to f15 which is super heavy.
Usability as defined by interaction design:
- Time to complete task after a specified time away from the product.
- Number and type of errors per task
- Number of errors per unit time
- Number of navigations to online help or manuals
- Number of users making a specific error
- Number of users completing a task specifically.
