How Vertical Spaces Are Perceived and Represented

چکیده
Introduction The purpose of this symposium is to highlight how the vertical dimension is perceived and represented differently from the horizontal dimensions, and the role of this dimension in spatial learning. This is a new and important issue because literature on spatial cognition has hitherto neglected the study of the vertical dimension, under the assumption that space can identically be investigated in the horizontal plane. This notion, while untested, ignores a crucial, unique property of the vertical dimension – that of being parallel to the force of gravity, which poses constraints on affordances and energetic potential. Additionally, the ability to move freely in three dimensions imposes computational complexities not present in two. New research impetus is trying to clarify the role of the vertical dimension in space. The present symposium will try to tie together different perspectives (psychophysics, cognition, neurophysiology), using different animal models (human and non-human), and different experimental methods (real and virtual environments), in order to provide a synthetic view on this issue, and to establish future goals of common interest. We focus here on two aspects of threedimensional space: surface properties (e.g., hills and valleys) and volumetric properties.

This Study has discussed the meaning of public space and has shown that public spaces are an essential part of people’s lives. It has also identified the key urban design and architectural ideologies that have influenced the shape of the built environment, and has discussed how each has perceived the value of public spaces. In the following provides an overview of the relationship between peopl...
متن کاملComparing the Microclimatic Role of Horizontal and Vertical Vegetation to Improving the Thermal Comfort of Outdoor Spaces between Buildings: A Case study (Faculty of Agriculture, I.K.I University), Qazvin.
Vegetation moderates a microclimate by casting shadows, increasing light reflection, evaporation and perspiration; and correcting wind patterns. The present study aims to investigate the microclimatic role of vegetated surfaces and bodies in improving thermal comfort in outdoor spaces between buildings. The main research question is which of the green system modes, that is, horizontal vegetatio...

Introduction: Shoe insoles are widely recommended to increase sport shoes comfort during running. However, relationship between ground reaction force frequency and perceived comfort is still unclear. The purpose of this study was to evaluate the relationship between ground reaction force frequency changes and perceived comfort during stance phase of running. Methods: 30 female students (mean...
متن کاملReasons for Creation of Important and Sacred Numbers and Their Reflections in Architectural and Urban Spaces
This research was an attempt to study reasons for creation of some of the important and sacred numbers and their reflection in architectural and urban spaces. This subject matter is important because significant and sacred numbers were used in design and construction of a number of historical spaces. The research objective was to discover some of the reasons for formation of important and sacre...
متن کاملAnalytical and numerical investigation of heat and mass transfer effects on magnetohydrodynamic natural convective flow past a vertical porous plate
The aim of this investigation is to study the effect of hall current on an unsteady natural convective flow of a viscous, incompressible, electrically conducting optically thick radiating fluid past a vertical porous plate in the presence of a uniform transverse magnetic field. The Rosseland diffusion approximation is used to describe the radiative heat flux in the energy equation. Analytical a...
