This chapter focuses on an aspect of programming that is too often overlooked—creating applications that are accessible to people with disabilities. There are few jobs today that don't require the use of a computer. Creating an application necessary to perform a job that can't be used by someone with a disability essentially denies that otherwise qualified person a job. This type of exclusion can and should be eliminated, as it creates a work environment that hurts people and companies. It can even be illegal for a company or government office to require the use of such software to perform a particular job. This chapter will present you with some guidelines for ensuring that your applications are accessible to as many people as possible, and as a result more marketable.
