Keyboard tester PT

This tool provides quantitative analysis of keyboard input quality. It records key events, computes per-key latency, detects debounce anomalies, and maps keys to layouts to verify consistency across devices. It targets developers, QA engineers, and accessibility testers who need objective timing data to validate keyboard-driven interfaces. By aggregating per-key metrics and exporting results, teams can diagnose hotkeys, mapping errors, or debounce issues that affect usability. The system is designed to work with multiple layouts (ANSI, ISO, JIS) and supports configurable sample sizes for CI integration. It differentiates itself by offering per-key timing profiles, layout-aware reporting, and straightforward export formats back to popular analysis pipelines. Typical use cases include validating input latency in new hardware, verifying debounce behavior after driver updates, and ensuring layout accuracy across operating systems. The tool emphasizes data-oriented insights over UI, focusing on reproducible measurements and clear, actionable metrics. Real-world scenarios include validating accessibility keyboards, gaming keyboards with rapid key presses, and standard office keyboards in cross-language environments.
