One Magic Formula to Calculate User Experience? (Wouter de Bres)

My quest for a formula to calculate User Experience started with a little experiment to see if I could calculate cognitive loading time of a design. When talking about loading speed of digital products the focus always seem to be the digital loading time, but we sometimes forget that trying to understand an interface also requires time – cognitive loading time. The more I thought and researched this problem, the more I discovered that loading time – digital and cognitive – might just be a small part of a bigger and more important question: Is it possible to quantify User Experience?
