Tablets with paper-thin screens that can be folded and tucked into your back pocket, artificial intelligence and augmented reality -- the stuff of science fiction may be coming to a store near you.
It's been two years since Apple Inc launched the iPad and spawned rival tablets from the likes of Samsung Electronics Co, Amazon.com Inc, Sony Corp , and now Google Inc and Microsoft Corp .
Much of the competition so far has centered on making smartphone and tablets lighter, slimmer, faster and longer-running than their predecessors, and the trend shows no signs of slowing. The increasingly crowded marketplace is also galvanizing hardware designers and software engineers to explore new technologies that may revolutionize the look and feel of mobile devices in coming years.
