Usability engineering

Usability engineering is about making sure things (like computers, mobile phones, websites, apps, games and any kind of digital product) are easy for people to use. It involves understanding how users interact with a product, and then designing and testing it until it meets their needs. Usability engineering is important, because it helps users feel comfortable and confident when using something and makes sure they can do what they need to do quickly and easily.
