“…At the beginning of the research, three general-scope questions were considered as evaluation metrics, concerning their own domain name, if they have virtual museums services and three-dimensional modeling support. However, in the scientific field of human-computer interaction, the factor of website usability was determined via specialized assessment/inspection methods [19], while the methodology of heuristic evaluation is a mainstream, easy-to-follow and inexpensive procedure [20] that guides evaluators to search shortcomings and problems [21] in technology-oriented assessment tasks. Furthermore, the usability tests were able to reveal and quantify the effectiveness, accuracy and completeness of the user experience of the design choices of a website/application, while they also examined the efficiency of the offered resources/content, towards meeting the users' needs and expectations, thus, providing a sense of the satisfaction, comfort and acceptability of use/interaction.…”
