Paco Hope #resist<p>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 <a href="https://infosec.exchange/tags/Ui" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Ui</span></a> and <a href="https://infosec.exchange/tags/UX" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>UX</span></a> of touch screens.</p><p>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 <a href="https://infosec.exchange/tags/touchscreen" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>touchscreen</span></a>. </p><p>My mobile <a href="https://infosec.exchange/tags/phone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>phone</span></a> (an <a href="https://infosec.exchange/tags/iPhone" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>iPhone</span></a> 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.</p><p>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. </p><p>I look at the <a href="https://infosec.exchange/tags/blackberry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>blackberry</span></a> keyboard in this photo and I see a raised space bar. It’s an <a href="https://infosec.exchange/tags/affordance" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>affordance</span></a> that lets you orient your fingers, and orient how you hold the phone, without looking.</p><p>I miss buttons. </p><p><a href="https://mobilesyrup.com/2025/02/15/blackberrys-expired-keyboard-patent/" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">mobilesyrup.com/2025/02/15/bla</span><span class="invisible">ckberrys-expired-keyboard-patent/</span></a></p>
