👆
OBJ — 04
Capacitive Touch Interface

Ultra-responsive touch sensing with multi-layout QWERTY, gaming, and numeric modes. Drag-and-drop key reconfiguration at runtime — no hardware changes needed.

Adaptive HMI
🔐
OBJ — 02
Layered Security Architecture

PIN authentication gated with SHA-256 hashing, retry lockout after 5 failures, forced system restart, and tamper-resistant hashed event logs. No plaintext ever stored.

Keylogger-Resistant
📡
OBJ — 06
BLE Wireless + GATT

Boots as a BLE HID device. Structured GATT service-based communication delivers low-latency wireless input with stable pairing and zero observed packet loss.

Wireless Native
🛡️
OBJ — 01
Kiosk Mode Isolation

Three-layer access control: private network isolation, controlled app launch, and runtime navigation restriction. Users interact only within the authorized interface environment.

Zero Escape
⚡
OBJ — 05
Reliability Engine

Per-key state-lock algorithm eliminates double-triggers. Debounce filtering (100–150ms) suppresses noise. State-transition-only output prevents false activation under any condition.

Zero False Triggers

Ambient RGB Feedback

Programmable ambient lighting provides live visual interaction feedback. Theme switching and layout state awareness at a glance. Ergonomics meets aesthetics.

// Security Stack

4 Layers.
Zero Compromise.

  • L1
    Access Control PIN-gated entry. Only authenticated sessions reach the keyboard interface.
  • L2
    Credential Protection SHA-256 cryptographic hashing. Credentials never stored or validated in plaintext.
  • L3
    Enforcement Response 5 failed attempts triggers logging, forced restart, and execution-state reset.
  • L4
    Tamper-Proof Logging All events timestamped and stored as hashed entries. Forensically traceable, modification-resistant.
✓ PIN verified
✓ Hash: SHA256
✓ Access granted
⚑ Event logged
✓ Integrity: PASS
