Towards the automatic evaluation of the quality of commercially-oriented Web interfaces

Usability is considered as one of the most important quality factors for commercial Web interfaces, along with others such as performance and security. However, most of usability evaluation methods for these Web applications do not support automatic measures. This paper addresses these issues through the presentation of an automatic evaluation model based on a systematic qualitative technique to validate the quality of commercially-oriented web interfaces. Thus, a case study was conducted to analyze and validate the feasibility of the approach by applying a quality model. The proposed model was based on four key usability items, which consists of 32 dimensions and 73 criteria. The results suggest that the main usability factors for commercially-oriented web interfaces are: appreciation of design, good quality of information, security/privacy of users and ease of use.
