CHALLENGE
Current Limitations
Existing input methods face limitations from physical and environmental constraints. SWAVI overcomes these limitations with surface friction-based input technology.
Existing Technologies Compared Physical Keypads, Touch Screens, Biometrics, RFID/NFC
Lack of Durability
Part Wear & Damage
Security Weakness
Traces, Tampering, Theft
Environmental Limits
Water, Dust, Noise, Vibration
Installation Constraints
Requires panel thickness & wiring
HOW IT WORKS
Technology Architecture Overview
SWAVI is an AI sound-based interface technology that detects micro-friction signals on surfaces and converts them into input commands through AI analysis.
Surface Friction Input
Sensors detect micro-friction sounds generated by the user's gesture on a surface
Signal Preprocessing
Digitization of the analog signal and organization into an analyzable form
Acoustic Feature Extraction
Extraction of the acoustic features that distinguish each gesture
AI Pattern Classification
A lightweight acoustic AI model classifies the features against learned patterns
Command Output
The classified result is mapped to an input command and delivered to the device
COMPETITIVE EDGE
Competitor Analysis
SWAVI overcomes the limitations of existing input methods, achieving robustness, privacy, and design freedom all at once.
Exceptional Environmental Robustness
Works even when wet, dusty, or with gloves. Accurate operation on curved and metal surfaces.
Superior Privacy Protection
No visual data is captured or processed — significantly more secure than camera-based technologies.
Hidden UI & Zero-Button Design
Enables a fully seamless UI without physical buttons, supporting premium, minimalist design.
| Technology | Input Method | Touch | Robustness | Privacy | Design Limitation |
|---|---|---|---|---|---|
| SWAVI | Surface Acoustics | Indirect* | Excellent | Highly Safe | None (Hidden UI) |
| Capacitive Touch | Electric Current | Touch | Low | Safe | Flat Surface |
| Smart Sensor | Pressure Force | Touch | Low | Safe | Panel |
| Mechanical Button | Mechanical Click | Touch | Moderate | Safe | Protruded |
* SWAVI's indirect-touch input: delivers input by rubbing the sensor-attached surface without directly touching the input device.
