ADAPT-O PILLOW: A SMART ORIENTATION-BASED INFLATABLE PILLOW SYSTEM

Adapt-O Pillow presents a prototype architecture for an orientation-aware inflatable pillow that brings together wearable inertial sensing, Bluetooth communication, user calibration, pressure feedback, and pneumatic actuation. Its core idea is to turn a detected stable sleeping orientation into a personalized pressure target and then use closed-loop feedback to bring the pillow to that target. Posture recognition is thereby kept apart from low-level pressure regulation, giving a clear structure for step-by-step implementation and testing. The documented prototype integrates ESP32-C3/MPU6050 sensing, a main ESP32 controller, an HX710B pressure-feedback path, pump and solenoid-valve actuation, and a web application into a coherent whole. Filtering and deadband logic limit unnecessary changes, and conservative pressure limits with manual or emergency deflation are specified as safeguards. The system is deliberately presented as an assistive comfort prototype, not a medical device. The chief limitation of the present work is that no quantitative evaluation is documented. Future work should measure orientation-recognition performance, pressure-regulation behavior, communication reliability, energy use, and user-centered outcomes under controlled conditions. Such an evaluation would show how well the architecture performs beyond functional prototype operation.
