What you say doesn&#x27;t change anything significantly, which means it doesn&#x27;t change the way we type on mobile phones--you still need to look at the screen. Also it&#x27;s a bit of a stretch thinking because it works on a game controller with limited number of inputs, it will work on a keyboard with way more keys, isn&#x27;t it?<p>As I mentioned above, I explored into building a mobile device that you can type into without looking, and my first hypothesis was &quot;tactile feedback is key&quot;. And turns out there are many many other factors at play. Even if Apple built something like you say, that won&#x27;t make more people buy iPhones, it&#x27;s just an incremental innovation that doesn&#x27;t significantly change any user behavior for the better.
