How to create a unique Website with an improved usability is an important task for many Website designers. This study was conducted to examine innovative Websites designed by 96 international design companies between 2010 and 2011, in which the idiosyncrasies of those innovative Websites were analyzed through literature review and interview with experts. People from different backgrounds were invited to assess the innovative techniques used for the design of those Websites and their usability. It was found that the expression techniques adopted by those innovative Websites can be divided into map-guided type, interactive game type, dynamic menu type, virtual reality type and visual context type, and that their respective usability problems are: users can easily get lost in the hierarchical structures of a map-guided Website; interactive game-based Websites often encounter problems with their interface deployment; dynamic menu-based Websites is not very interactive; virtual reality-based Websites can easily encounter problems with hierarchical structure and interface deployment; visual context-based Websites would often run into hierarchical structure problems. In this study, experiments were conducted to identify the usability problems with those innovative Websites. It is hoped the results of this study can serve as reference for Website designers to prevent Websites' usability problems.
