Report on Real-Time Monitoring of Stress, Heart Rate, and Heart Variability on Mobile Devices

Abstract

Chronic stress has become a ubiquitous issue in modern society, impacting both physical and mental well-being. Mobile devices, with their built-in sensors and processing power, offer a unique opportunity for real-time stress monitoring. This paper explores the current state of this technology, analysing its potential and limitations. We discuss the physiological markers used for stress detection, the technical aspects of mobile-based monitoring, including emerging advancements like ear worn sensors, and the role of machine learning in creating comprehensive stress profiles.  The benefits of real-time monitoring, such as increased self-awareness and biofeedback for stress management, are explored alongside the current limitations in accuracy and the importance of prioritizing medical consultations for chronic stress. Finally, we delve into ongoing developments in camera-based systems and address privacy concerns associated with this technology.
