Desarrollo de prototipo de aplicación móvil para permitir el reconocimiento de billetes estadounidenses para personas no videntes

Abstract

Blind people have great difficulties when it comes to identifying objects of daily life that do not have any tactile or auditory identifier, such as US banknotes. And these, to this day, have not implemented any tactilely identifiable differentiation system that allows this group of people to differentiate one denomination from another. In a search to solve this problem, in certain countries such as the United States, it was decided to provide its blind citizens with a device that allows banknotes to be easily identified, which does not happen for the rest of the countries that have as their currency. national the US dollar. In the present work, we propose the development of a mobile application for devices with Android operating system that allows blind people to identify the value of US banknotes using the camera of their devices and an image recognition system using artificial intelligence. . This application must comply with the accessibility guidelines for blind people established through an exhaustive investigation, since there are no universal guidelines established specifically for this accessibility case. The development as the framework for its execution to Scrum, which is part of the agile methodology and facilitates the management of implementation of functionalities during the execution of the project. The Kotlin programming language was mainly used, which is recommended for Android, and several frameworks that allowed the implementation of certain main functionalities.
