Breadcrumb Navigation: Further Investigation of Usage

There has been speculation that a breadcrumb trail also aids the user's 'mental model' of the site's layout to reduce disorientation within the site (Bernard, 2003); however, we have not found research to validate this assumption. It would seem logical, however, that a constant visualization of the path to the user's current location would increase their awareness and knowledge of the site structure.

A Comparison of Two Evaluation Techniques for Technical Documentation

This study compared two evaluation techniques, Usability Testing and Cognitive Walkthrough, in their ability to identify errors in aviation maintenance documentation. The techniques were evaluated to see how much unique information they each produced as well as the type of errors identified. Results showed that the techniques were complementary in their findings and both are recommended in the development of technical documentation.

Evaluation Toolbox for Aviation Technical Publications

This article describes the Evaluation Toolbox (Chaparro et al., 2004) - an aid to understand the process of evaluating the usability of aviation maintenance documentation -- from the initial development stage through the final pre-publication stage. This toolbox provides techniques to help technical writers better understand their users and to evaluate their documentation more effectively and efficiently.

Measuring Online Experience: It's About More Than Time!

Users' specific online activities, their knowledge of computers and the Internet, and how they feel about being online could differ significantly. In order to obtain a more robust measure, researchers may want to consider how and what users think, feel, and do online when they assess level of experience. In this article we explore each of these areas and present a new measure of measuring online experience.

Breadcrumb Navigation: Further Investigation of Usage

There are three different types of breadcrumbs represented in websites – path, attribute, and location. Path breadcrumb trails are dynamic in that any given page will show a different breadcrumb trail based on how the user reached the page. Attribute breadcrumb trails display meta information showing many different trails representing several possible paths to reach the page.
