Allocentric

A spatial reference frame in which locations and directions are defined relative to external landmarks or a fixed coordinate system, independent of the observer's own position or orientation. For example, "the shop is north of the park" or "there are two chairs side by side" are allocentric descriptions. In accessibility contexts, allocentric references are particularly important for people with visual impairments learning spatial layouts, as they help build survey-level cognitive maps that can be used regardless of where the person is standing. Research shows that people who are blind tend to use egocentric references more frequently but can benefit from developing allocentric spatial representations through tactile maps, 3D models, and collaborative spatial activities. The ability to switch between allocentric and egocentric frames is considered an important spatial skill.
