Been writing up some super basic notes on using “intuitive” tech for an octogenarian who has never used a touchscreen before and let me tell you, so many things people consider “intuitive” are absolutely not when you try to explain them from first principles. I think we’ve got worse at building truly intuitive interfaces in the last 20 years because no-one involved has known a time before many of these assumed behaviours existed
Old intuitive interface design was rooted in the concept of “affordance”, in that things did what they looked like they did, or felt they did when you touched them. Buttons were raised and went down, knobs turned, sliders only went back and forth. Now, nothing looks or feels like what it does; everything assumes a meta knowledge, something that is completely the opposite of intuition
