Google Maps One-Hand Zoom on iPhone
Think about everyone who doesn't see this post. Will they figure this gesture out? Did you? If it takes a blog post at the top of Hacker News for people here to find this, it's pretty far from discoverable. Is it really that great if most people can't use it?<p>On the other hand, you don't need any instruction for pinch-to-zoom. Intuitive interactions like that — or even double-tap-to-zoom — are much harder to come up with, but they're also accessible to everybody. This is a cool piece of trivia, but it's far from solving the one-handed zooming problem. I hope Google (or anybody else) is working on something to make this better for everyone.
