Freeware Helps Disabled to Click Accurately
“The hand moves the computer mouse, but the cursor doesn’t comply. The cursor doesn’t go where told.
The hand tries again. The cursor shoots past the intended target.
The hand tries a third time – and the cursor loops farther from the target than where it started. And the user is frustrated.
So it often goes for computer users whose motor disabilities prevent them from easily using a mouse.
As the population ages, more people are having trouble with motor control, but a University of Washington team has invented two mouse cursors that make clicking targets a whole lot easier. And neither requires additional computer hardware – just some free, downloadable software. The researchers hope that in exchange for the software, users offer feedback.
The Pointing Magnifier combines an area cursor with visual and motor magnification, reducing need for fine, precise pointing. The UW’s AIM Research Group, which invented the Pointing Magnifier, learned that users can much more easily acquire targets, even small ones, 23 percent faster with the Pointing Magnifier.”
