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

Journal of Advanced Transportation, Volume 2018, Issue 1, 2018., 2018 We propose a novel remote heart rate (HR) estimation method using facial images based on video analytics. Most of previous methods have been demonstrated in well‐controlled indoor environments. In contrast, this paper proposes a practical video analytic framework under actual driving conditions by extracting key HR inducing features.
