Proxemics

The study of how people use and perceive physical space in social interactions, originally defined by anthropologist Edward T. Hall in 1966. Hall identified four distance zones: intimate (0–45 cm), personal (45 cm–1.2 m), social (1.2–3.6 m), and public (beyond 3.6 m). In accessibility, proxemics is relevant in several ways: people with visual impairments may not perceive the spatial positioning of others, affecting social interaction; wheelchair users experience proxemics differently due to seated height and turning radius requirements; and in virtual reality, spatial relationships between avatars carry social meaning that must be conveyed through non-visual channels to be accessible. Built environment design also draws on proxemic principles to ensure adequate space for mobility aids and comfortable social interaction.
