Photoplethysmography for Measuring Cognitive Load in XR Environments: A Systematic Review
Advanced Sensor Research, Volume 5, Issue 3, March 2026.ABSTRACT Photoplethysmography (PPG) is a low‐cost, low‐power biosensing technology with growing applications in education, particularly for monitoring cognitive load in eXtended Reality (XR) learning environments. Measuring cognitive load is critical for preventing overload and optimising immersive learning, yet existing approaches such as self‐reports
