Many businesses are inaccessible for individuals with disabilities. This is in part because a usable method of determining building accessibility is not available for business owners. Although a number of guidelines for accessibility exist, they can be difficult to understand. In this paper, we present Access Tools: a smartphone-based application that allows a user to determine an accessibility rating for different building features. In Access Tools, users are guided through a number of questions to determine an accessibility rating for a building’s various features. Users can choose the order they answer questions in, and skip questions that are irrelevant to them. Measurement tools that use smartphone sensors help determine accurate answers to questions on-demand. Finally, the application’s help function can give the assistance to the user on the fly with survey questions and measurement tools. We anticipate that this application will provide faster, inexpensive and easy method of determining building features if it is accessible.
