Toronto: No more cribbing about scattered papers in office, no more complaining about bulky size of cell-phones. Very soon, markets will witness a sea-change in the cell-phone technology with the invention of plastic smart phones as thin and as a credit card.   

Canadian researchers have invented this phone which changes its shape depending on where it is stored. According to the researchers, the PaperPhone with its 9.5-cm diagonal thin film flexible display is a forerunner of paper thin handset and tablets of the future.
Describing their qualities researchers said that with this ultra-thin smart phone, users don't need a touch screen or buttons to make a call, play music, zoom, google maps or flip through e-books.

Rather, instructions are triggered by bending its corners, or rolling its right edge backward or forward. Bending it in different ways, triggers different instructions in its sensors. They said it does everything a smart phone does, like store books, play music or make phone calls.

It will be much more portable in comparison to any other mobile device because of its stretchy form of display and it will shape with your pocket because it senses its shape.

Lead researcher Roel Vertegaal who is the director of the University Human Media Lab at Queen's University in Kingston said, 'This is the future. Everything is going to look and feel like this within five years. You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen.'

With the invention of these ultra-thin smart phones, offices in future will not require paper or printers as users will be able to store and interact with documents on larger version of these mobile devices, say the researchers.

''The paperless office is here. Everything can be stored digitally and you can place these computers on top of each other just like a stack of paper, or throw them around the desk, says Vertegaal.
Describing another exciting technology, researcher Vertegaal said that he has also developed a wearable computer that bends to wrap around your wrist. Once you remove it, you can use it as a notepad.

Naming it a game changing technology, he says it will five to 10 years to mass market.
