Cognitive engineering is a big fancy word that basically means, making things that work well with the way our brains work. Just like how we use tools, machines or toys that are made to fit our hands, cognitive engineering is about making things that fit our brains.
You know how sometimes you might use a toy or a game that is really hard to figure out or play, and it makes you frustrated? That means the toy or game wasn't designed in a way that fits how your brain works. Cognitive engineering tries to prevent that frustration by designing tools, toys, games, and even computer programs in a way that follows the way our brains process information.
Cognitive engineers study how our brains work and how we think and learn things. They then use that knowledge to design things like computer interfaces or video games that are easier to understand and use. So the next time you play a video game or use a computer program that just makes sense, you can thank cognitive engineering for making your experience smooth and easy.
