Essential Diagnostic Tests for Input Peripherals
Input devices endure millions of mechanical actuations over their operational lifespan. Over time, physical switch contacts develop micro-corrosion, dust accumulation, or spring fatigue. Our Keyboard Tester logs exact JavaScript KeyboardEvent codes and physical scan codes across full, tenkeyless, 75%, 60%, and Apple Mac layouts. The Double Typing and Key Chattering tests detect debounce anomalies where a single key actuation registers twice within milliseconds—a classic symptom of failing mechanical switches.
Sensor Accuracy, Click Latency & Stick Drift Analysis
For mice and gamepads, precision is paramount. The Double Click Test measures the exact microsecond interval between mousedown events, identifying faulty Omron or Huano microswitches before they ruin productivity. The Mouse Polling Rate Test leverages PointerEvent coalesced updates to measure true reporting frequency up to 8000 Hz. Gamers can inspect controller thumbsticks using our Gamepad Tester, which computes resting center offset, circularity error, and deadzone integrity in real time to catch Hall-effect or potentiometer drift.
Typing Speed, Spacebar & Reflex Benchmarks
Beyond fault detection, our suite provides competitive typing benchmarks and click speed utilities. The Typing Speed Test calculates WPM and CPM across curated word pools, while the CPS Test measures raw click rate across 1s to 60s bursts. Spacebar Clicker evaluates heavy thumb switch stamina and detects double-actuations on large stabilized keys.
