The Steam gamepad and the Macbook&#x27;s new touchpads can simulate tactile borders and shapes on the surface with controlled vibration.<p>Combine with pressure detection and you can make Swype &#x2F; SwiftKey provide a sense of where you&#x27;re dragging your finger when swipe typing, plus that you can put emphasis on the right letters easily when swiping across groups of letters that would make for different words, making for better precision in the word suggestions.<p>It would also be much easier to implement gesture support by having areas much easier to target that you start gestures from or end them in. You&#x27;d also instantly get tactile feedback telling you if you made the gesture right or not, like for switching character sets or for moving the cursor.<p>Lots of gestures could be supported, where you&#x27;d essentially be &quot;asked&quot; with tactile feedback to push harder after making the gesture to activate the particular action. Suddenly you solved both accessibility, discoverability and precision, while reducing the error rate.
