RuView: Contactless Wi-Fi CSI Spatial Intelligence
Harnessing commodity 802.11 Wi-Fi Channel State Information (CSI) to decode sub-carrier amplitude and phase shifts for non-invasive human presence detection and vital signs monitoring — without a single optical camera.
The Sensing Paradigm
Traditional indoor monitoring relies heavily on optical surveillance, creating grave privacy compromises in private residences and clinical spaces. RuView treats ordinary multipath Wi-Fi reflections as a high-density radar interferometer. As humans breathe or move, RF reflections perturb the amplitude and phase across 52 to 256 OFDM subcarriers, enabling sub-millimeter physiological telemetry.
Key Technical Pillars
Phase Sanitization Pipeline
Eliminates carrier frequency offsets (CFO) and sampling time offsets (STO) through linear phase transformation in real time.
Respiratory Micromovement Extraction
Extracts 0.2–0.5 Hz chest cavity micro-displacements from noisy RF multipath environments using wavelet decomposition in Rust.
Zero-Allocation High Throughput
Engineered with zero-copy Rust buffers processing up to 1,000 CSI packets per second without runtime heap allocations.
Complete Privacy Protection
Generates spatial presence coordinates and vital telemetry without recording any visual imagery or identifiable biometric portraits.
