The total access system

In this paper, we describe the Total Access System (TAS) developed by the Archimedes Project at Stanford University's Center for the Study of Language and Information. The purpose of the TAS is to ensure everybody is able to access information regardless of individual needs, abilities, preferences and culture. Rather than modifying the computer that is to be accessed, the TAS provides individuals with a personal information appliance, called an accessor, that provides alternative ways to perform all of the necessary keyboard, mouse and/or monitor functions. With this approach, disabled users can transparently use the full capabilities of any system without penalty and with whatever performance augmentation they may require to be competitive.
