Digital art is a child of visual imaging computer technology. It starts with concepts developed from visual grouping and is then transformed into a digital artwork that integrates digital imaging technology. Today with the overall strong digital technology support, the field of visual image design is able to utilize highly digitalized means for the development of their many artistic concepts. This research aims to explore the possibility of visual illusion techniques in design education. According to "Gestalt Psychology," the research may help shed light on measuring the value of narrative text in the digital art classroom. Using visual illusion text as research means in in-depth interviews, the research adopts text analysis models based on grounded theory, and relevant supportive literature for the interpretation of the research participants’ responses. In addition, this research interviews 5 design education experts and scholars for additional supportive evidence from the perspective of educators’ sides. Notably, the research uses NVivo for the collection and interpretation of the data. The research aims at establishing a referencing point for educators in providing more effective design education, while students who refer to this research may better respond to one’s creativity in their creative works. Conclusions: 1. Visual illusion grouping requires visual experiences and storytelling to help realize one’s artistic expression. 2. The Gestalt theoretical principles tell us that the "visual principle" through art works may help heighten one’s perception and cognition. 3. The text clustering analysis may lead to further explanation in details. Cross-comparison of similar words shows us more on the significance and interpretation of the correlation the research proposes. It demonstrates to us that the research result derived from textual aspect analysis corresponds to the mental narrative according to the Gestalt theory. 4. With the help of computer and digital technology, the application of the research results may benefit digital art design education. Through the analysis as proposed on the digital art expressions, the research finds its way to six conclusive points. Without limiting themes or subjects, an educator may find it valuable in their classroom in working with students working on digital image works the ideas proposed in this research, some very practical and revealing tools for art educators.
