I recently drove a car whose whole control and entertainment system was a gigantic iPad-like thing mounted to the dash. It caused me to have a realisation about the #Ui and #UX of touch screens.
There is no way to touch a touchscreen without it treating that touch as intentional. What I mean is: without taking my eyes off the road, I can grope across the dashboard, find a knob or button—by touching it—without activating any function. Touching the volume button or temperature knob doesn’t DO anything until I do it with more force and intentionality. Not so for a #touchscreen.
My mobile #phone (an #iPhone 13) has no dead space in its face. There’s no part of the phone face I can touch without it assuming I meant to do that and I wanted to activate whatever was under my finger. Old iPhones that had physical home buttons also had dead space to either side: a safe space to hold the phone without DOING anything.
Computer keyboard have little raised pips on the F and J keys so you can find them by touch without looking. I do this all the time. But I don’t type the letters F or J. Touch screens have no such affordances.
I look at the #blackberry keyboard in this photo and I see a raised space bar. It’s an #affordance that lets you orient your fingers, and orient how you hold the phone, without looking.
I miss buttons.
