Optimal User Study
* Large volume of visually impaired persons
* App automatically converts model based on real-world version
* One group uses app to practice new space; control group does not
* Both groups navigate new space: Previously explained & surprise routes
* Study intends to show that automated conversion produces a map which does assist in real-world navigation.
Compromises:
* Sighted individuals
* Questionaire instead of real-world navigation
* Model is based on hypothetical building
