The first laser picks out imperfections in the surface of a tabletop while the second laser focuses on microscopic imperfections highlighted and uses those to direct the cursor.
The technique, dubbed dark field microscopy, allows mice to be used on almost any surface, including glass as long as it is more than 4mm thick.
“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.”
The two models, a desktop Performance Mouse MX and the smaller travel Anywhere Mouse MX are priced at Us$99.99 and US$79.99 respectively.
