Object Localisation

The process of determining the position and location of an object within a physical or virtual space. In accessibility, object localisation is a key challenge for blind and visually impaired users interacting with spatial interfaces, virtual environments, or graphical content. Non-visual techniques for object localisation include auditory displays (sonification, 3D audio), haptic feedback, and combinations of both that help users build mental models of where objects are located without relying on sight.
