A review of fuzzy Delphi method application in human-computer interaction studies

Abstract

The Fuzzy Delphi Method (FDM) is one of the research methods used in obtaining experts’ consensus on specific issues. FDM is a combination of the Delphi method and fuzzy theories. Although there are benefits of using FDM, but literature review on its application in the domain of Human-Computer Interaction (HCI) is still insufficient. Thus, this paper provided a review on FDM, including its application in the HCI domain. This paper begins with presenting a background on methods, discussing its benefits and weaknesses, comparing between the Delphi method and FDM, as well as steps in FDM. Several articles between 2015 and 2021 were reviewed. The study also examined FDM application in HCI in terms of field domain, number of experts, and data collection. This paper revealed FDM as one of the methods to obtain expert group consensus using a new construct of model or evaluation framework for user experience, augmented reality, usability, mobile applications, and online learning domain. The number of experts suggested for FDM implementation is ten. This paper mainly contributes in providing an overview on FDM in terms of conceptual, steps, and applications with a clear understanding for future studies.
