Systematically Evaluating Equivalent Purpose for Digital Maps

Brandon Biggs, Brett Oppegaard, Bruce N. Walker, David Sloan, James M. Coughlan, Nicholas A. Giudice

The Map Equivalent-Purpose Framework defines three items and fifteen criteria to determine if non-visual maps serve the same purpose as visual maps.

Claims

C1strongest claim

The MEP Framework provides a replicable methodology for comprehensively assessing digital map accessibility, clarifying WCAG's 'equivalent purpose', and guiding compliant and usable map creation.

C2weakest assumption

That the three defined items (Generalized, Spatial Information, and Spatial Relationships) together with the 15 measurable criteria fully and accurately capture the equivalent purpose of visual maps for non-visual users without omissions or over-specifications.

C3one line summary

The MEP Framework uses three purpose categories and 15 criteria to evaluate map representations, finding that tables and turn-by-turn directions fall short while Audio Maps and similar methods succeed in conveying equivalent spatial information.
