Image perception for adolescent of mortise-and-tenon joints in wooden buildings

ABSTRACT Wooden structure and the process of extracting elements are performed together with the adolescent. Young people have gradually forgotten ancient wisdom hidden in traditional objects. Traditional East Asian wooden architecture use mortise-and-tenon joints with various types. We have summarized the main types of wood structure joints and selected joint styles for image perception analysis. First, the joint structure is simplified, and the CAD digital model of the objects was established to facilitate the understanding of its structures and assembly approach. Second, connecting elements were extracted into five functions and shape types. Four stages questionnaires were used to survey feedback to verify the main recognizable features. The initiative’s primary intended outcome is 30 adjective with each sample which have differences in their cognition. After summing up by factor analysis, they can more clearly know the difference in image cognition between mortise-and-tenon samples.
