Abstract
The goal of much work in Virtual Environments (VEs) to date has been to produce innovative technology but until recently, there has been very little user-centered, usability-focused research in VEs that will turn interesting applications into usable ones. There is beginning to be at least some awareness of the need for usability engineering within the VE community. A handful of articles address usability concerns for particular parts of the VE usability space. From this point Gabbard and Hix [1997] has proposed a taxonomy about usability characteristics in VEs to help VE usability engineers and designers. This taxonomy can be used to learn characteristics of VEs or to develop usability engineering methodologies specifically for VEs. In this study, we built hypermedia representation of the taxonomy and evaluated the effectiveness of the user interface by using scenario based formative usability engineering method that developed by Hix and Hartson [1993]. First, we discussed the need for usability engineering for VEs and took a look at a proposed usability engineering methodology [Gabbard and others, 1999] for VEs. Second we implemented hypermedia based web-site taxonomy and then evaluated it iteratively. Last, we added a new study to show the dynamic nature of web-site application.
