In innovative education, tech- nologies can play a crucial role in teaching people with disabilities (PWD), offering new perspectives in learning. In this context, this work is specifically aimed at individuals with visual impairments, specifically those with total loss of vision, whether congenital or acquired, or even for individuals interested in learning Braille. The learning needs in this case are based on sensory per- ception, such as touch, taste, smell, and hearing. Therefore, the objective of this study is to present a cloud-based architecture that integrates a tactile reading device and Braille display, which is simple, low-cost, and uses a lightweight messaging protocol like the Message Queuing Telemetry Transport (MQTT), widely used in Internet of Things (IoT) architectures. In this architecture, the entire process of converting text into Braille occurs in the cloud. The used device has voice com- mands issued, received, and processed through an Application Programming Interface (API), commonly known as API, which performs the conversion of text to Braille. Then, the device prepares to display the points in high or low relief in a Braille cell, representing each character of the text. In this way, the visually impaired person can read the character through touch sensitivity. This architecture could provide a practical and accessible solution for learning Braille and for reading by visually impaired individuals, enabling greater inclusion and active participation in the educational process.
