Technology blogs have been abuzz that smartwatches may soon
be on their way from companies such as Apple, Google, Samsung and Microsoft.
But as capable as these ultra-small computers may be, how will users enter an
address, a name, or a search term into them? One solution is an iterative zooming
technique developed and tested by researchers at Carnegie Mellon University.
Called ZoomBoard, this text entry technique is based on the
familiar QWERTY keyboard layout. Though the full keyboard is impossibly small
on a watch-size display, simply tapping the screen once or twice will enlarge
an individual key until it can be comfortably and accurately pressed.
