Logitech debuts Darkfield Laser Tracking technology

Posted on Saturday, August 22 2009 @ 15:55:38 CEST by

Logitech announced Darkfield Laser Tracking, a new mouse technology that promises to enable you to use your mouse anywhere you want, including clear glass and high-gloss surfaces.
“Laptops have gained popularity in the last several years because of the freedom they afford – people today want to be able to connect to their digital world anytime, anywhere. However, until now, no mouse has been able to match that flexibility,” said Rory Dooley, Logitech’s senior vice president and general manager of the Control Devices business unit. “Thanks to Logitech Darkfield, whether you’re checking the morning news from the granite counter top in your kitchen or at work manipulating a spreadsheet from your glass desk, you can be confident that your Logitech mouse will be up to the task.”

A pioneer in the development of the computer mouse in the 1980s, Logitech has enthusiastically driven nearly every major innovation in mouse technology – persistently refining this ubiquitous interface between people and their digital experiences. From laser tracking to hyper-fast scrolling to the Plug-and-Forget Nano-receiver, Logitech has dedicated itself to creating ways to help you get more out of your computing experience. The latest in this line of innovations, Logitech Darkfield opens up new possibilities for when and where you can use your mouse.

Regular laser tracking technology relies on the ability of the mouse’s sensor to detect the textural details of the surface. The more irregularities a surface exhibits, the easier it is for the sensor to identify reference points that it can use to accurately measure motion. However, because high-gloss surfaces such as glass are almost completely flat, there are not enough details for a typical laser mouse’s sensor to detect.

To track on glass (that’s at least 4 mm thick), Logitech Darkfield uses dark field microscopy to detect microscopic particles and micro-scratches on these surfaces, rather than tracking the surface itself. Similar to the way in which our eye sees the clear night sky, 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.
