Abstract
This study aims to remove some of the ambiguities of visual plagiarism in interior design (those related to the visual composition of space represented by line, form, shape, texture, time, colour, light, etc.) by examining the main detection methods, the extent of the issue, and the experiences and roles of academic interior designers. Two main methods were used: an analysis of the primary forms of visual plagiarism and an applied approach to test the effectiveness of plagiarism. Additionally, 30 academics in the Kingdom of Saudi Arabia, who majored in interior design, were surveyed using an online questionnaire. The results demonstrated that changing the light and colour while maintaining the rest of the properties and changing the line, form, and shape are considered visual plagiarism. However, the results also indicated that visual plagiarism is not always clear for academics. It is hoped that the results of this study will increase the awareness of visual plagiarism, enhance ethics in the university environment, and help academic interior designers apply scientific methods to detect plagiarism in design projects. This study can also assist regulatory authorities to manage complaints and disputes in plagiarism cases.
