Blind learning terminal supporting multi-modal interaction and personalized learning evaluation

Abstract

This invention proposes a learning terminal and method for blind students that supports multimodal interaction and personalized learning assessment. The device integrates a Braille dot matrix display, an input keyboard, and a multimodal authentication module. Through two-way Braille interaction and a low-latency response mechanism, it enables real-time courseware conversion and efficient teacher-student interaction. Its core lies in a built-in algorithm for assessing blind students' learning abilities and generating personalized strategies. This algorithm focuses on five ability dimensions: Braille reading and writing, device operation, auditory attention, spatial orientation, and social interaction. Combining dynamic difficulty adjustment and individual development trajectory analysis, it accurately models the learning status of blind students and automatically generates targeted educational support strategies, providing teachers with data-driven decision-making support.
