Daedalus in the Dark: Designing for Non-Visual Accessible Construction of Laser-Cut Architecture
summary
A Fusion 360 plugin named Daedalus generates laser-cut layouts plus tactile aids (engraved lines and arrows, hollow entry circles and layered ground supports) by building an undirected assembly graph, running breadth-first layering and a star search for engraving paths, and detecting joint types from contours. Co-design with 7 blind participants yields heuristics; a validation study with 8 blind participants on five models shows higher completion accuracy and faster pairing and more stable assemblies, demonstrating the aids materially improve non-visual assembly.
