Smartphones, Tablets, and now wearable computers (Google Glass and Sony SmartWatch). The recent past has seen the invention of a variety of gadgets which promise to make our computing experience easy. The main objective of these inventions is to bring gadgets with different processing capacities and, more importantly, different display sizes. The invention of Gadgets with different display sizes is necessitated due to the different needs we have with gadgets. A smartphone with a smaller display size offers a different kind of utility when compared with a tablet which is more suitable for reading and watching movies. But carrying these multiple gadgets when you are on the move is harrowing. Imagine carrying a smartphone in your pocket, a tablet in your hand, and a laptop in your backup. All these gadgets are essentially similar functionality but have different display sizes and different processing capabilities.

But imagine a single gadget which can easily fit in your pocket and can ‘create’ multiple display sizes depending upon your need. At one stroke this will remove the need of carrying multiple gadgets with you. Scientists working at the Carnegie Mellon University have recently demonstrated a new technology which can just accomplish this. The technology dubbed as ‘Worldkit system’ enables you to rub any surface like a wall, table, your doors and convert them into touch screens. The technology uses a depth camera system like ‘Kinect’ along with a projector to turn any surface into a touch screen.

Earlier, the technology needed bigger projectors to achieve this feat. Recent advancements in the technology have however made it possible to use smaller projectors and light bulbs which can be fixed in any portable gadgets like smartphones and even watches. The opportunities such a technology opens are numerous. With processors and flash memory shrinking in size, companies can create ultra smart gadgets similar to the current smart phones which can have good processing and memory capabilities along with the ability to ‘create’ screens with multiple sizes depending upon the need. Future gadgets sporting this technology can very well make the current smartphones and tables obsolete.

The technology for now can only turn any surface into a touch screen. But scientists are hoping that Worldkit system can create touch screens in free space (thin air) in future.
