Physiological Response Indexing & State Monitoring Device

The Physiological Response Indexing and State Monitoring (PRISM) system is proposed as a child-oriented wearable device paired with a mobile application. The wearable collects physiological and motion-based biometric signals, including heart rate, galvanic skin response, and inertial motion, which are used to identify changes in the user's state. Collected data are transmitted to the mobile application, where they are stored, analyzed, and displayed to provide simple feedback and coping suggestions through linked resources. The wearable includes child-friendly visual indicators to promote self-awareness, while the companion application allows parents or guardians to monitor trends and provide support when needed. The system is designed to be low power, noninvasive, and unobtrusive, with an emphasis on data security and user safety. The proposed design aims to support emotional awareness and basic state management for children experiencing stress, anxiety, and attention-related challenges.
