Preference technique: deceptive visual representations in the digital realm

Abstract

In the digital era, architectural designs can be quickly visualized. However, the material abstraction from digital visualization tools may reduce immersion and make it hard to recognize design intention. This paper discusses how architectural students acknowledge the design representation, despite various ways of visualization. Material is key to visualizing architecture in ways of adding realism, depth, and texture. People create mental concepts of material beyond words. Thus, design representations can have positive or negative impacts depending on how effectively the idea is delivered to the audience. This study uses a quantitative method to investigate the extent to which the preference technique of students represents the design’s idea. The main objective of the study is to identify the criteria for representation that effectively convey the designer's intentions while minimizing visual deception. The analyzed data is classified into three archetypes consisting of (1) the student’s previous knowledge about representation, (2) the intention of design representation, and (3) mass and material in representation. The result shows that there is no strict correlation between previous knowledge and the preferred technique to represent an idea. Yet, the result indicates that there is the correlation between previous knowledge and technique to represent material. The photorealism technique is preferable in representing the clarity of material in representation. There are advantages to using photorealism in showing the quality of shade in the material. On the other hand, to show information about scale and mass, respondents tend to choose to use sketches. The research comprehensively explains this phenomenon in the context of positive theory, particularly in design communication and representation.
