When we had the boom about User Experience last years, all of us were astonished; "Yes! That's it!". But do you already stopped to think if it really was discovered in the last 10, 20, 30 years?
We used to use the UX (User Experience) expression to referee about digital interaction, interfaces — any kind of them — and digital services. But the truth is that User Experience is much more than just a good experience about all of these stuffs.
Our first register about user experience design comes from almost 600 years ago with Leonardo da Vinci (always him) and his not successfully try of a functional kitchen designed for a high-society party, what means the first record about UX is a fail and a bad client experience.
