(Phys.org) ?If you did not hear it from somebody else, you probably asked the same question yourself: What would I really do with a smartwatch, if it's for viewing only, when I need something for text
entry too? Viewing is only half of the equation, when you need to find the location of a school or key in any urgent instruction. After all, text input on a watch screen? No way? Way. A Carnegie Mellon team has come up with a concept translated into something called ZoomBoard, a keyboard that zooms when you tap it. ZoomBoard enables text entry on ultra-small devices, such as a smartwatch screen, using what the team calls "iterative zooming" to enlarge tiny keys to a size that is comfortable for the user.
