IntelliEye optical tracking technology gives IntelliMouse Explorer unsurpassed precision and control by replacing moving parts with an optical sensor that tracks movement.

This mouse has no moving parts to collect dirt, dust and grime, a mouse ball never needs to be cleaned.

IntelliMouse Explorer works on virtually any surface, eliminating the need for a mouse pad.

Two new customizable function buttons provide effortless Internet navigation with their forward and back default settings.

The neat buttons, located on the left side of the mouse, can also easily be mapped to execute useful program shortcut commands, like print or cut and paste.

• IntelliEye Technology - provides unsurpassed accuracy over time by replacing mouse-ball technology with an optical sensor and digital signal processor (DSP). 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 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 provide effortless Internet navigation with their forward and back default settings. The buttons, located on the left side of the mouse, can also easily be mapped to execute useful program shortcut commands, like print or cut and paste.
• Precision over time - With the new IntelliEye technology, there are no more mechanical parts to become worn or dirty!
• A proven ergonomic design allows users to align their hand and forearm in a natural, relaxed position on the mouse. The shape of the IntelliMouse Explorer supports the entire hand and fingers, while the slope helps keep the hand and forearm aligned naturally.
