I thought this concept was bigger than the focus. 🙂

For those of you without any background in UX, read Don Norman's The Design of Everyday Things. You won't look at the world the same again. https://www.amazon.com/Design-Everyday-Things-Revised-Expanded/dp/0465050654/ref=sr_[…]nFzcCI6IjEuNjIifQ%3D%3D&sprefix=the+design%2Caps%2C131&sr=8-1

Currently I am working on Open Learning Server, this book sounds like a great read to that objective. Thanks @Brian
