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.

Since its Android operating system is basically geared for touch-screen technology, rather than keyboard technology, Google's mobile market strategy is aimed at taking on Apple's iPhone and iPad that use touch screen technology.

The acquired Toronto company will no longer sell its software independently after May 7.
In a statement on its website Monday, it said, "Today, we have a big announcement to make: we're excited to announce that we've been acquired by Google! This means that BumpTop (for both Windows and Mac) will no longer be available for sale. Additionally, no updates to the products are planned.''

The acquisition of BumpTop is the fifth such deal by the Mountain View-based Google within a month as part of its strategy to take on Apple.

Just last week, it had acquired Labpixies that develops social games for mobile services and Facebook. Agnilux, Plink, and Episodic are the other three acquisitions made by Google within a month.
