Playing in Perfect Time: A Method for Synchronizing Scores, Avatars, and Game Elements With Precision

Sensorimotor synchronization (SMS) supports not only music and dance but also reading, language acquisition, and sports performance. Neurological and developmental conditions such as Parkinson's disease, dyslexia, or ADHD can impair SMS, limiting motor coordination and cognitive abilities. Rhythm‐based video games provide a motivated interactive training tool for clinical contexts. However, commercial rhythm games often have problems with timing accuracy, overly broad response windows, and a lack of feedback, which makes them less useful for therapy or research. This work introduces a method designed to achieve precise synchronization in rhythm games. The method enables the translation of music scores into a component field in the Unity Inspector and generates game elements and interaction windows aligned with auditory cues and avatar movement. The method addresses existing limitations by ensuring strict response windows, accurate input logging, and balanced audiovisual integration. Evaluation against theoretical onset times showed a small and stable synchronization error (mean error = 5.164 ms, RMSE = 5.697 ms, median shift = 5.200 ms), supporting the timing accuracy of the proposed system. It provides a robust foundation for rhythm games supporting training, rehabilitation, and education.
