Since the advent of all-touch smartphones and tablets, pinch-to-zoom has been a hallmark of intuitive gestural interaction. And while it's
intuitive, it's unfortunately not very
convenient - it's awkward at best, and almost impossible to accomplish one-handed. The team at Google Maps must have realized this, and
designed a one-finger zoom: double-tap anywhere on the map, and drag your finger up or down to zoom in or out. Those blue circles and arrows shown in this illustration aren't actually onscreen - as with all gestural interfaces, real estate is at a premium and visual clutter is a no-no, which leads some to
call this feature a "secret." But Google appropriately assumes that users will be quick learners - especially when the benefits are so compelling!
