Finding 3D CAD data production methods that work for people with visual impairments

Abstract

This study presents available 3D CAD data production methods that work for people with visual impairments. Standard CAD programs rely heavily on GUI, making it impossible for them. The best way for them to produce 3D CAD data would be to describe the 3D data file itself. As one of such methods, SCAD direct source input method is introduced. It then presents objects produced using that method to illustrate the effectiveness of such methods.
