Prioritizing the Usability Criteria of Adaptive User Interfaces of Information Systems based on ISO/IEC 25040 Standard
Priorisation des critères d’utilisabilité des interfaces utilisateur adaptatives des systèmes d’information basé sur la norme ISO/IEC 25040
Résumé
Usability is a major concern within adaptive user interfaces. It presents a combination of different attributes. The impact of each usability attribute may vary from one layer to another during the usability evaluation of adaptive user interfaces. On that basis, one question that arises is: “What are the priority levels of usability criteria that need to be assessed in individual layers and in the whole adaptive system?" This paper presents possible directions to address this question by identifying the priority level of usability criteria to be assessed in the adaptive user interfaces of information systems, considering the ISO/IEC 25040 standard. The priority level is calculated using a multi-criteria decision analysis method, namely the Analytic Hierarchy Process. The proposed approach provides guidance for evaluators to better evaluate adaptive user interfaces. An adaptive information system in the field of transport is presented in order to validate and illustrate our approach. © 2017 Lavoisier.
