🧠 Behavioral typing sensor and rhythm analysis layer for the FastJava ecosystem.
FastKeylogger transforms raw hardware events into high-level behavioral typing signatures. While standard loggers only capture characters, FastKeylogger captures the biological rhythm (dwell times, flight times) and cognitive patterns (correction behavior) of the user.
import fastkeylogger.FastKeylogger;
public class Example {
public static void main(String[] args) {
FastKeylogger logger = new FastKeylogger();
logger.addListener(event -> {
System.out.println("Typed: " + event.character() + " (Hold: " + event.durationMs() + "ms)");
});
logger.start();
}
}- 📝 Text Reconstruction — Converts raw hardware scancodes into a logical character stream.
- ⏱️ Timing Signatures — Captures precise Dwell Time (hold duration) and Flight Time (inter-key latency).
- 🧠 Correction Awareness — Monitors backspaces and deletions to analyze cognitive load and error patterns.
- 🎯 Zero Polling — Purely event-driven logic based on
FastKeyboardraw input callbacks.
