![]() ![]() > Improving Browsing Performance (Shumin Zhai, Barton Smith, Ted Selker) The concept for the 'ScrollPoint' started in 1997 at the IBM Alamden Research Center to determine the most efficient way to scroll through documents. Regardless, it does have a following of few who like the ergonomy and enhanced scrolling ability. A few reasons may be that (1) most people don't like change, (2) the ScrollPoint performs too fast without drivers, (3) IBM didn't push marketing or continue to really develop the product into the mainstream. Speed is controlled based on the pressure applied for continuous-dynamic scrolling this reduces the strain on the finger caused by standard scroll wheels and also allows the user to adjust the speed on a variable basis (not fixed to a set interval at any given time).Īs ScrollPoints offer superior functionality to the standard 'wheel' mechanism, it's very curious why this alternative design never overtook standard mice. As the ScrollPoint mechanism operates on an X/Y axis it allows 360 degree scrolling (although without drivers installed it will only operate with vertical scrolling and at rather fast rates). ![]() The original ScrollPoint mouse debuted in 1998 to combine the similar TrackPoint mechanism as found on the ThinkPads to replace a standard mouse wheel. ![]()
