Eric Michelman
Eric Michelman is credited with inventing the now commonplace computer input device known as the scroll wheel. Scroll wheels are most often located between the left and right-click buttons on modern computer mice. Michelman attended MIT's Sloan School of Management in the 70s.
History
In 1993, Michelman began work on his project to ease zooming within Excel. His interest in eased navigability stemmed from real-time observation of users entering data in spreadsheets.
“…as I was watching many Excel users do their work, I noticed the difficulty they had moving around large spreadsheets. Finding and jumping to different sections was often difficult. I had the idea that perhaps a richer input device would help.” [1]
Michelman looked to add a 'zoom-lever' for the left hand to control while navigating the Microsoft GUI. After experimenting with a joystick assigned to throttle-like zooming, Michelman approached Microsoft's engineers with his idea. In his position as Program Management Lead for the Excel project, he persuaded the hardware engineers to develop added functionality of the current hardware to allow richer input. (He insisted on zooming, but they persuaded him that a panning, or scrolling wheel would have wider applications.)
After appealing to the hardware engineers and subsequently conceding to the idea that a scrolling function would possess the greatest overall utility, Michelman was charged with organizing the software support for this new function. Being the Program Management Lead for Microsoft’s Excel spreadsheet productivity tool, he was well positioned to achieve this, and did.
Advances in Technology
There have been many advances in computing mice since the dawn of the scroll wheel. 1999 brought the advent of a marketable LED technology optical mouse from Agilent. [2] Close following in the same year, Microsoft released its version of an optical mouse, the Intellimouse Explorer.
Michelman's brainchild has since been elaborated on by the likes of Logitech, Apple, and other major computer peripheral manufacturers. In 2007 Logitech combined all of these technologies and more when the company released a 7-button, 2-wheel, fully customizable mousing device aptly named "MX Revolution." This technology is intended to address a user's need when
"The typical computer user has six applications open and switches windows every 50 seconds. In a work day, we rack up 26 feet on the mouse's scroll wheel." [3]
Other Contributors
A jointly developed mouse by Japanese (NTT) and Swiss (ETH) companies may mark the first appearance of a wheel-function on a mouse back in 1985. They developed what was a thumb wheel for their companies, the (original) "Mighty Mouse." [4] This mouse did not catch any traction in the world computing market.
Additional work by Michelman
Before working at Microsoft, Michelman is reported to have developed Terminate and Stay Resident programming for DOS at Borland Software Corporation. Michelman has also been prolific in participating in the production of patents pertaining to different ergonomic and navigability properties of computer input implements.
