Sightbased

Sightbased is an adjective used to describe systems, methods, or theories that rely primarily on visual information to perceive, interpret, and respond to the environment. The term is not tied to a single discipline, and its meaning can vary by context, but it generally implies an emphasis on sight as the principal data source rather than other senses or modalities such as hearing, touch, or proprioception.

In technology, sightbased approaches are common in computer vision and robotics. They use cameras and image processing to extract features, recognize objects, track motion, and guide decision making. In user interface design, sightbased interfaces prioritize visual cues and feedback as the main channel of interaction, while acknowledging that many systems still incorporate multimodal input to support accessibility and context.

In cognitive science and psychology, sightbased processing refers to perceptual systems that give priority to visual information, though multisensory integration can modulate perception and behavior. The term is also applied in security and surveillance to describe monitoring methods that depend on visual data from cameras and line-of-sight observation rather than solely on non-visual sensors.

Advantages of sightbased approaches include access to rich, high-resolution data and intuitive interpretability for humans. Limitations include dependence on lighting and visibility, vulnerability to occlusion, and higher computational demands for real-time processing. The term is used variably across fields, and its precise scope depends on the domain in question.
