摘要：In Colombia, the participation of people with some disability in the different educational levels is still deficient. Although it has been growing since 2010, the CNPV estimates that the illiteracy rate for the population with some disability is still three times higher than the national figure. However, the country has been adopting a policy of Inclusive Education focused on reducing barriers to learning and participation for all, which implies a high level of commitment and understanding by the entire educational community to achieve good practices. When analyzing the specific case of people with visual impairment, it is evident that one of the main mediating agents of inclusive education is teachers. They, in some cases, have led their students' reading-writing process to be ineffective due to their lack of knowledge in the Braille language. An example of this is the significant amount of time they take to transcribe texts in Braille, decreasing the ability to evaluate or rectify whether or not the student understands a text, preventing timely feedback. This situation hinders how students learn, understand, and produce texts. Therefore, the use of technological tools that facilitate the teaching work is proposed by developing applications for transcription of Braille text to literary Spanish both on mobile devices and personal computers to minimize this problem and support the teaching-learning process in the classroom. Initially, the article describes the application developed for mobile devices with an Android operating system and the software application developed for PCs using Matlab. Subsequently, the performance analysis of applications is presented in terms of processing time, transcription error percentages, and response to different test conditions. Finally, the results and improvements concerning previous works are presented in terms of versatility and robustness achieved in detecting Braille dots, cells, and characters with different lighting characteristics and types of sheets.
