Toronto, May 4 (IANS) Google Monday snapped up a top Canadian startup which pioneered a 3D interface technology for Mac and Windows PCs.

Called Canada's hottest software startup, Toronto-based BumpTop has been acquired by the search engine for reportedly between $30 and $45 million, according to reports. However, there were no details of the deal by the two sides.

Set up just three years ago, BumpTop has pioneered touch-screen software that allows use of multiple fingers at a time on a multiple touch screen.

Called 'desktop workspace,' the software allows users to organise pictures, documents and videos much more intuitively. Users can perform many functions with their fingers, including dragging of items into docks, and playing around with photos on desktop.

Though Google has not specified how its will use this pioneering technology, it is certain that it will use touch-screen software in its smart phones based on its Android operating system.
