Eric Michelman
Eric Michelman, a graduate from MIT, 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.
== History ==
In 1993, Michelman began work on his project to ease navigation 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.” 〔(【引用サイトリンク】 url = http://www.ericmic.com/history%20of%20the%20scroll%20wheel.htm )〕
Michelman initially looked to add a 'zoom-lever' for the left hand to control while navigating the Microsoft GUI. After experimenting with a joystick assigned to panning (scrolling) as well as 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 to the current hardware to allow richer input and then evangelized the new functionality to the other Office applications. A debate raged over whether all the Office applications should have the same scrolling or zooming default, with Michelman subsequently conceding to the idea that having them all, including Excel, scroll by default would possess the greatest overall utility. Michelman was charged with organizing the software support for this new function. Being the Program Management Lead for the Excel project, he was well positioned to achieve this, and did.
