Optical tracking - Reduce sticking and constant cleaning with optical tracking – a system that works through light with less moving parts for greater durability than ball-based mice.
Users benefit from a smooth, contoured shape that fits both hands – and a wheel that functions as a third button.
The optical sensor within the HP USB Optical Scroll Mouse employs a scan rate of 800dpi and enables crisp motion without a mouse pad, ball or roller.
