Technology Report-A Better Computer Mouse Cursor for the Disabled
|
|||
|
Using a computer mouse or trackball can be a little tricky. You choose the object you want and move it to where you want it, only to have it end up in a different position. This happens to all of us sometimes, and we think little of it. But for people who have a difficult time controlling their movements, this little navigational issue can be a really big problem. Now, researchers at the University of Washington have developed new cursors that make activating objects easier for people with motor disabilites. Jacob Wobbrock is an assiatant professor at the University of Washington. He leads the AIM Research Group that developed the cursors. Professor Wobbrock says mouse cursor operations are complex processes that assume things about computer users. JACOB WOBBROCK:" For many people who have poor dexterity, the inability to control their fingers well, maybe pain in their wirsts or hand, maybe arthritis-those assumptions of the average user, they don't hold." The AIM Research Group has developed two cursors. One is called the Pointing Magnifier. Professor Wobbrock says it uses a large circular cursor instead of the traditional arrow pointer. JACOB WOBBROCK:" And they can make that circle as big as they like. So, if their motor impairments are fairly severe, they can make that circle large. When the circle is positioned over the target, everything in the circle appears larger, almost filling the whole screen. This makes it easier for the user to click on the object. JACOB WOBBROCK:" At this point the user sees the regular point cursor now, the little arrow, inside that exploded magnified view. And with that they can move and click on the target they want or they can begin to drag the target they want. The AIM Research Group's Pointing Magnifier software can be downloaded free from the University of Washington website. AIM is short for Accessible, Interactive and Mobile. Professor Wobbrock says the group's main goal is to make information and computer systems more available and easier to use. And he says AIM's work is not just for people with disabilities. JACOB WOBBROCK:" Some of our projects have looked at what we call situational impairments, which are challemges to accessibility that are caused more by the situation or context that the computer user is in instead of maybe as we usually think of accessibility as having to do with someone's own physical or cognitive state." Professor Wobbrock says an example of this might be using a small mobile device while walking. |
