VR-Based Assessment for Picture-Book Storytelling Training: A Preliminary Research

Picture-book storytelling fosters preschool children's cognitive and literacy development in Japanese childcare centers. However, training childcare workers remains challenging due to the need for emotional engagement and adaptive strategies. This study develops a VR-based storytelling training system that enables trainees to practice in an immersive environment with virtual child avatars. The system evaluates performance based on voice volume, reading speed, posture, gaze, and eye contact, providing real-time feedback. An expert evaluation confirmed the system's validity but identified areas for improvement. Adaptive scoring for voice and reading speed, tracking of page-turning techniques, and body orientation assessment should be incorporated. Additionally, realistic child reactions and adjusted gaze evaluation for children sitting on the floor are needed.
