Accessibility assessment of buildings: design and implementation of an advanced Android application

A4A fill and go is an Android application developed to help assessing whether a building of public interest can be considered accessible and usable for mobility and visually impaired people. It represents a useful and practical tool that directly allows the measurement of a considerable amount of data, stored in a database, and processed applying some innovative evaluation rules proposed in "Accessibilità e Fruibilità dei luoghi di interesse culturale: metodi, strumenti e soluzioni" by Eng. V. Giacometti. The app not only shows the evaluation obtained by the building under analysis in a clear form, using the literals from A to E, but also dynamically updates the grades obtained by the various groups of architectural components while inserting new information. Among the functionalities provided by the app it is possible to produce an external report, useful for technical reasons, and to export the database for further studies in a proper format. The user can also upload maps or blueprints of buildings that can guide through the fill out process of the different components by adding markers onto them, facilitating the measurement process while walking inside a building. The app targets technicians, but will have a positive impact on impaired people that will physically benefit the results of the measurement collection. Knowing in advance the accessibility grade given, let's say to a museum they might want to visit, can be vital for those people and their assistants that would be able to learn in advance the practical obstacles that might prevent them from enjoying their visit.
