Israel-Austin company raises $24 million. Firm plans to expand work on touch-screen technology.

N-trig Ltd., an Israeli technology company with Austin operations, has raised $24 million in its latest investment round from investors that included Microsoft Corp.

N-trig, based in Kfar Saba, Israel, makes computer touch-screen devices that allow PC users to control functions with the swipe of a finger or with a pen.

The company, which employs about 100 people worldwide, operates a sales and customer support office in Austin for its North American business.

The 10-year-old company's DuoSense input screens are employed in Dell Inc.'s Latitude XT tablet computer and Hewlett-Packard Co.'s TouchSmart tx2 notebook.

N-trig CEO Amichai Ben-David said his company will use the money to develop new applications for its technology, expand its global supply chain and "penetrate new markets."

Microsoft, the lead investor in N-trig's latest round, is incorporating more touch-control technology in its forthcoming Windows 7 operating system.

Touch screens are an expanding feature in personal computing and an alternative to a mouse and keyboard for some uses.

"The mouse, I think, is gone," Ben-David told the Wall Street Journal. "I don't see a reason to have one."

N-trig uses so-called capacitive touch technology, which senses when a finger is nearby, so the user does not have to actually touch the screen.

Part of the investment will support N-trig's work to assist software companies that want to develop touch-based programs to work with the Windows 7 operating system, which is expected to be released within the next year.

"By simulating the way people write and touch naturally, N-trig is helping to make it easier to navigate your PC and enable a new class of Windows experiences," said Ian LeGrow, Microsoft's group program manager for Windows client software.

The other investors were Aurum Ventures, Challenger Ltd., Canaan Partners and Evergreen Partners.
