Abstract
En el área de la medicina gran parte de los esfuerzos están centrados a enfermedadescrónicas que afectan a la población, sin embargo, existen otras aristas en la medicina las cualesno han recibido el mismo nivel de esfuerzos, ese es el caso de las discapacidades físicas,cognitivas y sensoriales [9]. En la actualidad se estima que cerca de 295 millones de personasen el mundo padecen algún tipo de discapacidad visual, de los cuales 39 millones son ciegos[8]. Aunque no clasifica como una patología que comprometa la vida del paciente, le generagrandes dificultades para desarrollar su vida con normalidad e insertarse en la sociedad actuala un gran número de personas.Es por lo anterior que se dedican los esfuerzos del presente trabajo de memoria de titulación a aportar en el desarrollo de ingeniería enfocado a personas con ceguera. Para ello, sedesarrolla un programa informático capaz de convertir imágenes en señales acústicas, con lafinalidad de que el usuario pueda percibir su entorno visual mediante el uso del sentido de laaudición.El programa es escrito utilizando el lenguaje de programación Python y consta principalmentede dos partes; una que realiza el procesamiento de imágenes y extrae la informaciónrelevante, y otra que en base a la información otorgada por el anterior realiza la generación desonidos audibles mediante la utilización de un lenguaje de programación llamado CSound.En un entorno controlado, se somete a diferentes pruebas a un grupo de usuarios sin experienciade uso del dispositivo, con las cuales se comprueba la efectividad del prototipo, juntocon los tiempos que requieren los usuarios para lograr realizar determinadas actividades.
Most of the achievements and studies within the medical field are focused on chronic diseasesaffecting the population, however, there are other facets in medicine that have not receivedthe same level of attention, this is the case of physical, cognitive, and sensory disabilities[9].Nowadays, about 295 million people worldwide suffer from some type of visual disability,out of which, 39 million are completely blind [8]. Even though, this condition is not a pathologycompromising the life of the patients, it generates great difficulties in their everyday lifeand it complicates their incorporation into society.Due to the aforementioned facts, the present work aims to contribute in the developmentof engineering to improve the life of people suffering from blindness. In order to achieve thisgoal, a computer program capable of converting images into acoustic signals is developed,allowing the users to perceive their visual environment by using the sense of hearing.This program is written using the Python programming language and it consists of twoparts; the first one performs image processing extracting relevant information, while the secondone uses the information provided by the previous one to generate audible sounds througha programming language called CSound.Under a controlled environment, different tests are performed within a group of userswithout experience using the device, in order to check the performance of the prototype, alongwith the times required by users to complete certain activities.
