Visual Affordance

A visually conveyed cue that signals how an object can be used or what it represents - for example, a handle suggesting 'grasp', a button suggesting 'press', or color and labeling suggesting product identity. Many visual affordances are inaccessible through touch alone: blind and low vision users cannot perceive that two identically shaped bottles contain different products, or that a label indicates caffeine content, without alternative description channels. Designing accessible interfaces and assistive technologies that surface visual affordances non-visually - through audio description, tactile substitution, or AI-generated narration - is a core accessibility challenge.
