Don't just alert. Connect.
A smart communication system for the deaf. Sound to vibration, gestures to speech. A bridge for your daily environment.
Real-time telemetry for sound classification and gesture mapping.
All sensors calibrated and ready for real-time interaction.
How SIGNAL bridges sound and communication
A high-speed sensory pipeline that translates acoustic events into haptic alerts and hand gestures into human speech.
Acoustic Event Detection
Real-time microphone monitoring identifies doorbells, alarms, or speech, converting audio into precise haptic patterns.
Gesture Recognition Engine
Translates hand signs from the communication glove into intent, using k-nearest-neighbors for reliable pose matching.
Synthetic Speech & Display
Converts recognized gestures into clear, synthesized speech and text, bridging the gap for non-hearing visitors.

Technical Architecture
A bridge between sound and touch. Our system uses local browser intelligence to translate environmental audio into haptic alerts and hand gestures into speech.
Real-time sound classification engine that maps environmental audio to specific haptic vibration patterns.
- Live microphone amplitude monitoring
- Cosine similarity for custom sounds
- Zero-latency classification pipeline
Low-latency processing of flex sensor data to translate hand signs into synthesized human speech.
- Steady-state pose detection (0.8s)
- k-nearest-neighbours classification
- Real-time finger deflection mapping
High-fidelity 3D visualization of hardware states, providing visual feedback for every haptic alert.
- Real-time wristband vibration HUD
- Dynamic finger articulation model
- Orbit controls with motion toggle
All audio and gesture data is processed locally on-device. No data is ever uploaded to external servers.
- Audio processed in memory buffers
- Gesture models stored as JSON
- No cloud-based telemetry tracking
Standard Alerts vs. SIGNAL Bridge
Traditional flashers only notify; SIGNAL connects. Compare our haptic-gesture bridge against legacy systems.
| Feature | Legacy Systems | SIGNAL ACTIVE |
|---|---|---|
Alert Latency Performance | Variable; depends on manual setup | Sub-10ms haptic response time |
Sound Recognition Intelligence | Basic fixed-frequency detection | Adaptive AI sound fingerprinting |
Gesture Accuracy Interaction | Manual slider-based input only | Real-time IMU & flex sensor fusion |
Visitor Bridge Communication | null; requires manual typing | Live text-to-speech & visual panel |
Hardware Integration Flexibility | Hardwired, non-portable systems | Modular ESP32 & wearable design |
Privacy & Security Compliance | Cloud-dependent audio processing | 100% local on-device processing |
Total System Cost Cost | $2,000+ for professional installs | Accessible DIY hardware components |
