<p>There is no shortage of startups attacking the virtual keyboard space, as you'd expect with so much scope to improve the experience of touchscreen typing. Yesterday Toronto-based Whirlscape launched a beta version of its Qwerty-squashing Minuum software keyboard, for instance. Today it's SnapKeys' turn. The New York based startup is readying the full launch of its Si Evolution invisible keyboard, which we last covered at its December beta launch, due to land on Google Play in the next day or so.</p><p>SnapKeys says it's racked up between 50,000 and 100,000 beta testers (i.e. app downloads) since then. Its Android keyboard software disrupts the traditional Qwerty layout by grouping letters into four islands, with more commonly used letters appearing larger than others. This arrangement leaves the majority of the screen empty to display whatever is underneath.</p><p>Indeed, even SnapKeys' four key-carrying islands can be made invisible once the user is comfortable they know where they need to tap. An entirely invisible keyboard is clearly one better than the translucency Apple has added to its native keyboard in iOS 7, allowing content like photos to be viewed in full at the same time as typing.</p><p>The most notable change in the full version of SnapKeys' keyboard software as it comes out of beta is that it's switched the order of the letters to an alphabetic one, instead of its prior arrangement (right) which required users to learn an entirely new letter order. Clearly that was proving a disruption too far.</p><p><a href="http://techcrunch.com/2013/06/19/snapkeys-exits-beta/">Keep reading...</a></p>
