To address this, a Vietnamese Braille raised letter board has been developed to support learning and work for the visually impaired in the digital age. This board can incorporate advanced artificial intelligence (AI) algorithms to control tactile feedback mechanisms, facilitating the learning of Vietnamese Braille characters for the visually impaired. The board is integrated with advanced sensors and actuation mechanisms. Both laboratory and real-world experiments have demonstrated that the Vietnamese Braille raised letter board accurately receives and displays signals from a computer and quickly responds to Braille characters through an electromagnetic drive system. The tactile feedback mechanism ensures that the raised Braille dots are durable and user-friendly, providing a rich sensory experience on the fingertips of the visually impaired users. Furthermore, the Vietnamese Braille raised letter board also includes modules for signal reception and transmission, enabling the emission of sound to enhance listening and reading comprehension skills for the visually impaired individuals. This innovation aims to empower visually impaired individuals, allowing them to access educational materials and information more effectively and independently.
