A cursor for disabled

The research group has published two AIM software for Windows intended to help disabled people to use a mouse. The Mouse Pointing Angle Magnifier and are downloadable for free. Some disabilities make using a mouse difficult because of the precision that is sometimes necessary to click on a specific corner of the screen.

AIM includes scientists from the University of Washington who tried to find a solution to this problem. Pointing The Magnifier creates a circle around the cursor. It is possible to adjust its size to customize the interface disability. The more the user has difficulty manipulating a mouse, the smaller the circle is large.

Once the mouse positioned on the place you want to achieve, clicking the left button shows a magnifying glass that magnifies the selected location. It is easier to click a button or link, for example. Scientists have warned however that their system still had some defects. It is impossible to use mouse events mouse over or hover.

For example, if the menu is set to be hidden and only appear when the mouse reaches the bottom of the screen, Pointing The Magnifier will not bring up the taskbar. In addition, context menus can not be magnified. The other software, Mouse Angle adjusts the speed and trajectory of the cursor and helps those with difficulty holding a mouse.

The system ignores the sporadic movements or inconsistent. Cursor movements are also slowed as it approaches its target, to help the user to position it correctly. Testimony on the Internet says that this software can even benefit people with all their motor skills, because it optimizes the movement of the mouse.

This second program is more advanced and more innovative than the first. These two programs are the result of studies and papers published by researchers. They require the presence of. NET Framework 2.0 and is licensed under New BSD.
