| Abstract |
Information asymmetry is the biggest reason for variations and change orders in the field of construction. These issues lead to increased
construction period and cost, legal claims, and disputes. Especially, the design of a special tree is difficult for clients to perceive the
description of the tree due to the limited experience and information. Consequently, designers have used representation tools such as 2D CAD
or BIM to make their proposals easier for clients to understand more intuitive. However, existing representation tools require professional
knowledge and the ability to imagine or shape the information, which intensifies difficulties in communication between practitioners and
clients. Thus, more immersive realistic models in virtual-reality or mixed-reality environments are applied in the design review process to
support decision-making. In this study, the mixed reality was introduced to determine whether it could be used as a representation tool while
supporting the client’s special tree design decision-making. To verify this hypothesis, an experiment, about the installation of a special tree in
the landscape design review phase, was conducted to compare mixed reality with the 2D CAD drawing plans, which is the representative
design proposal representation. In addition, 12 questionnaires are classified by each category, understanding of space, understanding of
greenery, and decision-making supporting. Mann-Whitney U test and paired t-test were conducted to analyze the significance between previous
representation tools and mixed-reality about the understanding of space, design, and greenery. In addition, the correlation between
understanding and decision-making support for landscape design review was analyzed by applying the Pearson correlation coefficient. As a
result, it was found that mixed-reality is more intuitive and easier than 2D CAD drawings to understand essential information such as spatial,
design, and scale information in the design review phase of a special tree. Even with the technical limitations of tactility visualization in
mixed-reality, quick introduction of this innovative tool would support clients to determine the size and installation location of a special tree. |
