Measuring and selecting an effective user experience pattern for commercial web applications
Abstract:
Web interface design patterns provide solutions to recurring design problems. A category of user interface design patterns offers several design solutions and techniques to solve the same design problem. A large number of solutions can lead to confusion and make it hard to compare one solution to another, or even to a benchmark. Novice designers, therefore, may have a difficult time in choosing the right solution to a design problem. Moreover, designers often do not know whether users would be satisfied with their chosen choice until near or at the end of the web development process. In this study, factors affecting the ease-of-use of a user interface design pattern were determined. A new measurement and selection framework for design patterns was also developed. This framework is consisted of four metrics: 1) human action (HA), 2) non-human action (NHA), 3) all action count (AC), and 4) maximum continuing human action (MCHA). Ease-of-use scores were examined among thirty task-based design solutions, which were developed for the study. The analysis of the results showed that the value of HA, AC, and MCHA were inversely related to the ease-of-use scores whereas the value of NHA and the ease-of-use scores showed a positive relationship. The developed framework was also evaluated against two other design techniques: with and without using design patterns. The evaluation results showed that the developed framework obtained the highest satisfaction score from novice designers. Novice designers also indicated that the developed framework could be used to improve the design process in their real work setting and reduce communications among stakeholders. Considering the ease of use, both the developed framework and design pattern online library received equal ease-of-use scores.
