Research and Development of Reading Visual Aids for Low-Vision Individuals Based on Virtual Reality Technology
Sponsor: Beijing Tongren Hospital
Summary
Low vision substantially impairs reading ability and educational participation in adolescents. Existing assistive technologies, including optical magnifiers and electronic visual aids, are often limited by fragmented system architectures and insufficient support for multimodal cognitive processing. This study aimed to develop and evaluate a virtual reality (VR)-based intelligent reading aid integrating image enhancement, optical character recognition (OCR), text-to-speech (TTS), and large language model (LLM)-based semantic summarization for low-vision users.

VR-Based Intelligent Reading Aid
Intervention Description： Participants use the VR head-mounted intelligent reading aid to complete the same standardized reading tasks. The device integrates image enhancement, OCR, text-to-speech (TTS) and LLM-based semantic summarization. The test luminance is set at 400 nit (maximum recommended brightness). Each task contains 100 Chinese characters. Duration：Single session, approximately 5 minutes
Natural Vision Reading (No Assistive Device)
Participants complete reading tasks with natural vision, without using any assistive device.
