Incorporating the user's model of a task. Understanding the user's conceptual model is the basis of our design process: what concepts and tasks does the user have in mind already? How will that affect how she uses your product? This article is a case study of user research from consulting projects. Download the user model document (PDF).

Creating a home page. Your home page may be the most important part of your Web site. It's the first thing that many visitors see, and it has to get your message across quickly. People are always looking for the next thing to click on, and won't spend time interpreting long text or unclear marketing messages. Read tips on creating a home page.

Using color in UI design. I had a wonderful experience a few years ago, working with Ati Gropius Johansen. She teaches a course called Dynamics of Color, which I took. I wound up teaching a workshop with her and writing an article on using color in UI design; it's based on Josef Albers' ideas about color. Ati is the daughter of Walter Gropius, founder of the Bauhaus School, and was a student of Albers. She's a great teacher.
