Design and Analysis of Vietnamese Braille Printer for Visual Impaired

The Braille printer is a revolutionary assistive technology designed to efficiently cater to the needs of the visually impaired. It converts digital text and graphics into embossed Braille, granting easy access to printed materials. With advanced features like high-quality embossing, user-friendly interfaces, seamless connectivity, and support for tactile graphics, this state-of-the-art Braille printer significantly improves the quality of life and opportunities for visually impaired individuals. This paper presents a simple, low-cost, and easy-to-operate Braille printer, developed through a comprehensive review of relevant literature and an exploration of its design and development process. The printer head is constructed using an Electromagnet mechanism, the movements of the printer axis are driven by the stepper motors, and the main processing unit is an Arduino board. The printer's performance is appraised through expert opinion in the field of Braille text.
