This chapter has highlighted some of the features that should be a part of every development process to ensure that applications are accessible to everyone who needs to use them. While it might be impossible or impractical to include everything mentioned here in every application, you should consider this a strong guideline. For more information on accessibility issues, including detailed guidelines and resources, and on Active Accessibility, check Microsoft's Web site at http://www.microsoft.com/enable. Extensive research has also been done on this topic at the Trace Research & Development Center, University of Wisconsin-Madison. You'll find their Web site at http://tracecenter.org.
