Title: Web guidelines and usability
Abstract: In this study, user performance differences has been examined over time on two interfaces, which differed in terms of their implementation of a defined set of web guidelines (i.e. one that conforms to the guidelines and one that contradicts the guidelines). Two web sites were designed using web guidelines derived from the literature. The content covered in both sites consisted of a list of recipes and nutrition-related information, contained in five different sections: (1) Vitamins, (2) Minerals, (3) Nutrients, (4) Recipes, and, (5) Nutrition Info. Various features were manipulated so as to present an Ideal web site (i.e. one that conformed to a stipulated set of guidelines) and a Non-Ideal website (i.e. one that contradicted them). Manipulation involved the use of color (i.e. with respect to colors used in the background and the pictures), visibility of menu options, color of unvisited and visited links, and, the use of frames. Pilot testing of both interfaces showed that users performed better in using the Ideal than the Non-Ideal site.
