This paper presents the "Letter Explorers" platform, an educational tool designed to support preschool children in their writing acquisition process. The platform was designed based on recognized pedagogical guidelines, structuring its activities into progressive levels of difficulty. The main focus is on learning letters and encouraging independent writing, respecting the motor and cognitive development of young children. Its features include real-time visual and auditory feedback, which helps correct and reinforce learning, as well as the possibility of personalizing activities based on the child’s name, a factor that contributes to motivation and engagement. The proposal aims to serve, especially, educational contexts in the interior of emerging countries, where access to quality digital solutions may be limited. Preliminary results indicate the potential of the tool to promote an interactive, inclusive and contextualized environment for learning to write in preschool education.

This paper presents a computational approach for the machine translation of comic book texts, aiming to promote linguistic accessibility, particularly in emerging countries. The proposed system performs end-to-end processing: it detects text regions, extracts content using Optical Character Recognition (OCR), translates the text into the target language, and reinserts the translated content into the original image, preserving its visual structure. Built with open-source libraries, the system is lightweight and suitable for low-resource computational environments. The methodology was validated through an experiment involving 1,000 pages of comics in four languages—English, French, Spanish, and Japanese. Results demonstrated high accuracy in the OCR and translation stages for Latin-based languages, and satisfactory performance for Japanese, despite its right-to-left reading layout and ideographic characters. The tool also showed potential as an assistive reading solution, with applications in educational and inclusive contexts. This work contributes to the development of accessible technologies aligned with the United Nations Sustainable Development Goals (SDGs), particularly in promoting quality education and reducing inequalities.
