People with visual impairment often rely on their residual vision when interacting with their spatial environments. The goal of visual accessibility is to design spaces that allow for safe travel for the large and growing population of people who have uncorrectable vision loss, enabling full participation in modern society. This paper defines the functional challenges in perception and spatial cognition with restricted visual information and reviews a body of empirical work on low vision perception of spaces on both local and global navigational scales. We evaluate how the results of this work can provide insights into the complex problem that architects face in the design of visually accessible spaces.

Movement experts tend to outperform non-experts on some tasks of spatial ability, suggesting that movement experts possess enhanced spatial-cognitive abilities, which may be developed over years of practice. In the current study, movement experts (dancers and athletes) and non-experts completed one verbal working memory task and two spatial working memory tasks—a traditional Corsi block-tapping task and a new full-bodied version of the Corsi task, nicknamed the "Twister Task." Movement experts outperformed non-experts on both the Corsi and Twister tasks but not on the verbal task, suggesting that movement experience may relate to spatial working memory specifically. Additionally, the Twister task significantly correlated with the traditional Corsi task, providing validation for a new measure of spatial working memory. [ABSTRACT FROM AUTHOR]
