Sign language is an essential mode of communication for the hearing-impaired community yet learning it can be challenging for beginners due to the need for consistent practice and accessible instructional tools. Traditional learning methods often rely on human instructors or static illustrations, which may not provide sufficient engagement or real-time reinforcement. To address this gap, this study aims to design and develop a Robotic Sign Language Tutorial Device using an ESP32-controlled mechanical hand equipped with servo motors and display. The device demonstrates letters and words in Filipino Sign Language (FSL), accompanied by a small LCD display that shows the corresponding text. The robotic hand with a screen provides learners with visual reinforcement, allowing them to associate hand gestures with written language. The system was evaluated for accuracy in sign formation and the clarity of text output. Results indicate that the prototype consistently produced accurate signs based on comparisons with standardized Filipino Sign Language references and enabled intuitive touchscreen navigation as evidenced by successful user task completion, supporting its effectiveness as an assistive educational tool. The Robotic Sign Language Tutorial Device thus presents a low-cost, accessible solution that can enhance independent learning and bridge communication barriers for both hearing-impaired and hearing learners.
