Kathy Sierra has returned to the world of blogging after a 6-year hiatus, and her first post on her new blog is stellar. It’s called “Your app makes me fat”, and it’s a fantastic piece about cognitive load — that is, how much brain power you have to put into completing a task.
She talks about how cognitive load not only impacts how our users interact with our applications, but also how it impacts the lives of our users. It’s a great reminder that our user experience doesn’t stand by itself. Instead, our user experience is just a part of the day for our users. We often talk about “death by a thousand paper cuts”, and I think that we forget that those paper cuts still hurt even when our users leave their desks. After all, who hasn’t gone home after a bad technology day at the office and been unable to focus on anything else because they were so drained by what they’d experienced that day?
It’s a long post, and there’s a lot in there to think about. Make sure that you’re ready to settle in, read the post, and think about her points. I know I’m going to have to re-read it at another time when I’ve got more energy to focus on it.
