Tactile Fidelity

The degree of detail and accuracy in a tactile representation compared to the real object or concept it represents. High-fidelity tactile models include fine details, textures, and proportional accuracy, while low-fidelity models use simplified shapes and reduced detail to convey essential spatial relationships. Research in accessible design shows that both levels serve important purposes: low-fidelity models support initial orientation and overview comprehension, while high-fidelity models enable deeper exploration and understanding. The optimal fidelity level depends on the learning objective, the user's prior knowledge, and the context of use.
