Camera Guidance

Non-visual feedback systems that help blind users position a camera to capture usable images of documents, objects, or scenes. Guidance may include spoken directional instructions (e.g., "move up", "move left"), audio tones indicating proximity to a target, or vibration patterns. Effective camera guidance in accessibility applications reduces the time needed to capture OCR-readable document images and can serve as implicit training that improves users' proprioceptive camera skills even when guidance is not active.
