Commentary 21 Why ongoing study of targeted users is crucial for design success. Designing Information for Users Thyra Rauch IBM Corporation SWS/RTP Human Factors Research Triangle Park, NC trauch@us.ibm.com Wright has written a thought-provoking article on the evolution of document design and how some issues regarding document design might become the basis for a framework to support future efforts. Not only have GUIs evolved through the years, but the advent of first Web pages and then Web-based applications has changed the way we need to design documentation. And, as we look at the proliferation of small, hand-held, portable electronic devices, we should also consider the future of documentation for devices beyond the desktop computer. Documentation, in its traditional forms, is becoming ludicrous for many of these small devices, precisely because these devices are becoming embedded in other things so that we hardly realize they are there. How, then, is a user supposed to get assistance in using the device? New technologies can indeed lead to new ways to provide user assistance. And, new ways to provide user assistance can give rise, as Wright suggests, to new design problems. Beyond that, there certainly should be opportunities for users to
