IntelliMouse Explorer 3.0

IntelliMouse is a series of computer mice from Microsoft. The IntelliMouse series is credited with a number of innovations[1] - for example, Microsoft was among the first mouse vendors to introduce a scroll wheel,[2] an optical mouse, and dedicated auxiliary buttons on the side of the mouse. They use IntelliPoint drivers and its main competitor throughout the years has been Logitech.


The original IntelliMouse was introduced on July 22, 1996, with its stand out feature being its scrolling wheel.[3] Its design was based to that of the Microsoft Mouse 2.0 from 1993.

In 1997 Microsoft made the IntelliMouse Trackball, a variant featuring a trackball. In May 1998 the IntelliMouse Pro was released, a redesign of the original IntelliMouse.[4]

The IntelliMouse Explorer was introduced on April 14, 1999 at COMDEX. This new version featured IntelliEye optical tracking technology, eliminating the need of a mouse ball or mat. Microsoft called it the "most radical computer mouse technology and design advancement" since computer mice were introduced in the 1960s.[5] It was released on October 4, 1999.[6]

IntelliMouse Explorer 2.0 was introduced in 2003, including a wireless variant called IntelliMouse Explorer for Bluetooth. The 3.0 version was also made that year but later discontinued, before being re-released in 2006.[7]

On October 17, 2017, Microsoft revived the series with the new Classic IntelliMouse, featuring a new dark look based on the IntelliMouse Explorer 3.0 design and featuring BlueTrack technology, allowing it to be used on glass surfaces.[8][9]
