Logitech Performance Mouse M950

Laser tracking that works on virtually any surface and a tiny, leave-in wireless receiver put the power to achieve in your hand.

Logitech had announced the Performance Mouse M950. It is a wireless laser mouse which boast the company’s Darkfield Laser Tracking. It also features Hyper-Fast scrolling and come with Logitech Unifying Receiver. The M950 Wireless Mouse is targeted at right-handed users as it features a right-hand shape that fit your hand and four customizable thumb buttons plus a micro-USB recharging system that lets you use the mouse when charging.

Regular laser tracking technology relies on the ability of the mouse’s sensor to detect the textural derails 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 4mm 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 our eye sees the clear night sky, the mouse’s sensor sees the clean areas of the 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.
