Visual Accessibility and Inclusion. An Exploratory Study to Understand Visual Accessibility in the Built Environment.

Abstract

Current research shows that visual accessibility assessment in the built environment typically considers objectively measurable parameters. However, considering subjective visual perception for architectural characteristics is extremely important. Visual perception can vary depending on environmental factors and personal factors and is particularly relevant for people with low to mild visual impairments. This explorative research studied the current state of the art of tools and systems that support the assessment of visual accessibility and investigated new ways of experiencing visual accessibility in the built environment. After identifying gaps in the current scenario, the Cambridge simulation glasses were selected as a tool to simulate visual impairments and therefore experience visual accessibility in the built environment. A pilot study was conducted by navigating a publicly accessible building and experiencing how clearly visible certain architectural characteristics were, while walking with and without wearing the glasses. The goal of this study was to understand their potential use in different settings and explore how to offer an empathic experience of visual accessibility with a low-cost tool for different stakeholders.
