Multi-Fidelity Modeling

A design strategy that provides tactile representations at multiple levels of detail and complexity to support layered learning and comprehension. In accessible museum and educational contexts, this means offering simplified low-fidelity models (like 2D silhouettes or outline shapes) for initial spatial orientation, followed by progressively more detailed high-fidelity models for deeper exploration. This approach scaffolds understanding by allowing users to build a mental framework before encountering complex details, and is particularly effective for helping blind and low vision people comprehend large or abstract structures.
