The sensor snaps pictures of the work surface at a rate of 1,500 images per second and then translates changes between the images into onscreen movements. This technique, called image correlation processing, results in smooth, precise pointer movement. The shape supports your hand and encourages natural posture. The scrolling and zooming wheel lets users enjoy universal scrolling in their favorite applications directly from their mouse without having to use scrollbars.
Users can zoom without using toolbars or menus.
Two new customizable function buttons Browse the Web without using toolbars or the keyboard. Simply use either side button to go forward or backward on the Internet.

The shape of the IntelliMouse Explorer supports the entire hand and fingers, while the slope helps keep the hand and forearm aligned naturally. The IntelliMouse Optical comes with a five year hardware warranty.
