Multi-Sensory Experience in Inclined Planes - Focused on Claude Parent’s Oblique Theory -

This study aims to explore the characteristics of spaces with inclined planes and users' multi-sensory experiences, focusing on Claude Parent’s Oblique Theory. The Oblique Theory rejects the two basic directions of vertical and horizontal commonly used in Euclidean space for architecture and cities, proposing instead a diagonal design utilizing inclined planes as an alternative. According to Parent, experiencing inclined planes allows us to perceive our surroundings more subtly and enhances our sensory and responsive capabilities. This form of experience can be explained through the oblique effect and body schema. The Oblique Theory can be divided into diagonal design utilizing inclined planes and Gestalt psychology. This study selected four cases that meet the criteria of the Oblique Theory and analyzed the spatial characteristics and multi-sensory experiences on inclined planes based on diagonal design and Gestalt psychology. The findings show that the Oblique Theory is closely related to designs that use inclined planes, maintaining the flow of movement without interruption, and a landscape architecture mindset that connects buildings and topography naturally. Furthermore, through inclined planes, a continuous awareness of gravity is induced, allowing the body to become accustomed to imperfection and adapt to new ways of conforming to space.
