Research from User Interface Engineering and Jakob Nielsen.

As we worked on Trellix 1.0, we were pleased to find other research that provided more information in this area:
User Interface Engineering
One of the most influential to us was the extensive usability work done by User Interface Engineering (www.uie.com). We do a lot of usability testing at Trellix (one-way mirrors, video cameras, etc.) and have worked with some of the people there. Their publication, "Web Site Usability: A Designer's Guide", helps present some of their research. They are publicizing more of it through speeches, their web site, and courses.
Conclusions they have reached include the importance of writing clear, appropriate links, and the negative impact of animated graphics.
Jakob Nielsen (www.useit.com)
Another person who writes extensively about usability testing is Jakob Nielsen. He is a principal of the Nielsen Norman Group, a user experience consultancy. Until July 1998 he was a Sun Microsystems Distinguished Engineer and the company's Web usability guru. He writes a biweekly Alertbox column on Web usability (www.useit.com/alertbox/). He wrote a paper, "Concise, SCANNABLE, and Objective: How to Write for the Web" (available at "Writing for the Web") that has more research and more guidelines. This paper describes research that measures the impact of changing just the writing style (from promotional to scannable and objective) on usability of the material.
