8ware Touch 8 Mobile Digital Pen Designed for Windows 8

Touch 8, a cordless pen that works in tandem with an attachment that plugs into the Windows computer's USB port; Turn your ordinary screen to Touch Screen specially designed for Windows 8.

The attachment, which is really an infrared and ultrasonic receiver, clips magnetically to the side of the screen, which can be as large as 17 inches diagonally. The pen emits an infrared beam out of its tip. The receiver attachment sends the pen's signals to the computer, which interprets its precise location.

Pushing down on the pen results in a separate ultrasonic signal, which is equivalent to a touch screen sensing when you are touching it. Just like that, you can swipe and tap your way through Windows 8. The pen runs on a watch battery, which should last about 500 hours and is replaceable.

Windows 8, Microsoft Corp.'s effort to make desktop and laptop computers work more like tablet computers, was released in October to mixed reviews. A major problem is the fact that many of the features require a touch-screen monitor to work, making the experience unpleasant for those with older machines. 8ware Touch 8 offers a way for those with older computers to experience the newer touch-based functions.

Many people who have upgraded to Microsoft Windows 8 will not necessarily want to buy a new touch screen computer to take advantage of the many touch and swipe gestures in the new operating system.
