How it works

The regular mouse track movement by detecting the textural details of the surface. The sensor works well on irregular surfaces such as mouse pads or white paper. However, glass or glossy surfaces are almost completely flat hence the regular mouse sensors can’t detect movement.

Logitech Darkfield uses dark field microscopy to detect microscopic particles and micro-scratches on these surfaces, rather than tracking the surface itself. It’s like we look into clear night sky and seeing the stars as a pointers. The Darkfield mouse sensor sees the glass surface as a dark background and the dust as pointers to track the mouse movement.
