Desarrollo de un prototipo de gafas para lectura de texto con visión artificial que asista a personas con discapacidad visual

Abstract

Eyeglasses for reading text with artificial vision improve the ability of visually impaired people to function in their environment, accessing all types of information written using artificial vision and obtaining an adequate inclusion of these people in daily activities. For the first part the use of OpenCV was determined; in addition, it consists of a digital camera which takes a photo of the document that is wanted to read, then the image passes to a process of improvement, which by means of programming in language Python processes the same one using techniques of artificial vision to be later implemented in the converter of text to voice. Function tests were carried out to validate the prototype with people from the UNESCO Chair of the Salesian Polytechnic University, so that the glasses facilitate their inclusion. The tests performed took into account the distance at which the text is recognized and the clarity with which the words are pronounced by the voice of the system, in these two tests was obtained a minimum recognition distance of 20cm and for all users interviewed the clarity, volume and speed with which you hear the text is more than adequate to understand the contents. The people interviewed consider the system to be positive as a complementary part of the teaching since it allows for a better understanding of the texts and the proposed hardware was not a disadvantage for its use.
