New Logitech Mouse Works on Glass

Logitech just announced a new computer mouse that you can use almost anywhere – even glass surfaces! With Logitech Darkfield Laser Tracking, you can use your mouse on clear glass (that's at least 4 mm thick) and high-gloss surfaces. The new technology is available in the Logitech Performance Mouse MX, a full-size mouse, and the Logitech Anywhere Mouse MX for the notebook computer.

To track on glass, Logitech Darkfield uses dark field microscopy to detect microscopic particles and micro-scratches on these surfaces, rather than tracking the surface itself. The mouse's sensor sees the clean areas of glass as a dark background with bright dots (the dust). Then, the sensor interprets the movement of these dots to track exactly where you've moved the mouse. Pretty cool, huh?

The full-size Logitech Performance Mouse MX features four customizable thumb buttons and force-sensitive side-to-side scrolling (software enabled) – a first for a Logitech mouse – lets you quickly navigate around Web pages. It will be available this month for $99.99.

The Logitech Anywhere Mouse MX comes with a travel pouch helps and includes back and forward buttons, placed within thumbs reach. It will be available in August as well, with an MSRP of $79.99.

Both mice feature the Logitech Unifying receiver that stays in your notebook, so you don't need to unplug it. Up to five other compatible Logitech keyboards and mice can be added to the receiver.
