Information and user interfaces are often in a form not suitable for all terminals, or accessible by all users. A conventional computer system is typically directly coupled to its input and output devices, such as a keyboard, mouse and CRT. This restricts access to those able to use these devices, and it also restricts applications to those that are able to present and receive information using them.
Presented here is a paradigm that disconnects applications from input and output devices to enable interaction using personalized user interfaces and interaction models. The approach is based on the Total Access System (TAS) ( Scott 1991) originally developed to enable disabled users access to computers. Over time we have seen that technologies developed for disabled users have become conveniences for everyone else. This realization initiated work on how the TAS could be enhanced to provide a network of dedicated resources that when so combined provide personalized interaction with information technology appliances. We have called this the D.A.I.M.
The TAS simply consists of a "black-box" inserted between the computer system and its traditional input and output devices. This black-box, called a Total Access Port, or TAP, can now monitor, redirect and emulate all of the input and output devices.
