I love large touchscreens but I also love tactile feedback when typing, so unless I get a phone with a slide-out keyboard, I have to choose one or the other. I highly doubt I'm the only one with this problem. Fortunately, it may not be a problem much longer thanks to Tactus Technology. The California-based tech company recently revealed Tactile Layer, a technology that allows buttons to rise out of a touchscreen and then recede when you no longer need them.
Since the new touchscreen is replacing the existing layer, it wouldn't add any thickness. It's flat and transparent the company says it's "the world's first deformable tactile surface."
While this technology seems tailor-made for smartphones and tablets, given the rising popularity of touchscreens, there's a wide array of applications. The first Tactus products should be available by mid-2013.
