For fall detection devices, a sound approach must identify sensor type and wearing position, coverage zone, algorithm validation in similar users, sensitivity, false alarm rate, cancellation window, immobility logic, location accuracy, response delay, battery, charging gaps, connectivity, nighttime use, privacy, and manual call backup.
This guide focuses on the interpretation of results. It uses inertial sensor, sensitivity, and false alarm to explain what changes the outcome, where uncertainty enters, and which response is proportionate.
