To accommodate users with seizure disorders, including those with epilepsy, users can adjust screen elements, such as timing, color and contrast, and sound by using Accessibility Wizard or Control Panel in Windows. The range and selection in many of these features are expanded in Windows 2000. Users can also limit the number of fonts to one or more specified favorites. The following accessibility features can be customized for people with seizure disorders.
Timing patterns can affect users in many adverse ways. Users with seizure disorders, such as epilepsy, can be sensitive to screen refresh rates and blinking or flashing images. Settings in Windows 2000 Control Panel can prevent the default loading of animations and videos. Users can adjust the rate at which most objects flash to select a frequency that is less likely to trigger seizures. Users or administrators can alter the insertion point indicator (sometimes called the caret) blink rate, and can link it to flashing events for users who are sensitive to screen refresh rates. They can turn off blinking or flashing images.
In addition to users with hearing impairments or users in crowded or noisy environments, users with seizure sensitivity can also be susceptible to specific sounds. Settings in Windows 2000 can prevent the default loading of animations, videos, and sounds. Using Windows Control Panel, users can also assign custom sounds to any event. The ability to customize sound schemes, whether to turn sound on or off, or to adjust volume up or down, is becoming more important for users and takes many forms in Windows 2000 in support of people with various kinds of disabilities and requirements.
Through Accessibility Options in Control Panel and Magnifier, users can adjust color and contrast settings. New to Windows 2000 is an expanded spectrum of color schemes, customizable to suit a user's individual needs. For more detailed information, see the following section on visual impairments.
