Abstract: – Learning Braille depends on repeated tactile practice, yet beginners often practise with printed material or with a teacher present to say whether a pattern is right. This paper describes the design of BrailleLearn, a low-cost console in which six push buttons, arranged as a Braille cell, and a confirm button are read by an ESP32 microcontroller. After each attempt the learner’s six-bit pattern is compared with the target pattern, and the difference is resolved to individual dots, separating dots that were left out from dots that were pressed without being required. The accumulated per-dot error counts are intended to drive a targeted practice mode that favours characters involving the dots a learner finds hardest. Feedback is planned through LEDs and a buzzer, with an optional Bluetooth Low Energy link to a smartphone for spoken prompts and progress records. We review related work on refreshable displays, IoT assistive devices, and technology for Braille literacy, state the gap the console addresses, and present the hardware, software, and evaluation design. At the time of writing the physical prototype and firmware have not been completed; no measurements or user-study results are reported, and an evaluation plan is given in their place.
