This research aims to evaluate the effectiveness of employing an augmented reality-based Picture Exchange Communication System (PECS) to enhance the communication skills of autistic students in Indonesian language subjects. A systematic literature review collected and analyzed various studies integrating PECS with augmented reality technology in educational settings. The study comprised three stages: determining keywords, searching for article data, and determining inclusion criteria. The findings from this review indicate that augmented reality-based PECS significantly enhances verbal and nonverbal communication abilities among autistic students. Key advantages of this approach include increased interactivity, enhanced visualization, and heightened student motivation. However, challenges such as requiring specialized equipment and sufficient teacher training were identified. Additionally, the review revealed fluctuations in the number of publications on PECS use across different years. This research aims to contribute to communication training for autistic children, particularly in the context of learning the Indonesian language. This study aims to inform educational practices and stimulate further research in this area by highlighting the benefits and challenges of AR-based PECS integration.
