The Core Mechanism
1. Motion Detection
Inside the sensor are medical-grade accelerometers and gyroscopes (called an IMU—Inertial Measurement Unit). These components continuously measure the angle and position of your spine in three-dimensional space.
When you calibrate the device in an upright position, the sensor establishes your personal baseline. It then monitors deviations from that baseline in real-time.
2. Intelligent Algorithm
The onboard processor analyzes incoming motion data to distinguish between actual slouching and normal movements like reaching forward, bending to pick something up, or leaning into a conversation.
This smart detection prevents the false alerts that plague simpler angle-based devices.
3. Haptic Feedback
When sustained slouching is detected beyond your set threshold (adjustable from 1-20 seconds), the device activates a small vibration motor. This gentle tactile cue prompts immediate postural correction without requiring you to check your phone or consciously remember.
4. App Sync & Tracking
Via Bluetooth, the sensor transmits posture data to the companion app, where algorithms calculate your daily upright percentage, track progress over time, and adjust training difficulty as your habits improve.
