Text/code editor typing latency analyzer
Typometer is a tool to measure and analyze visual latency of text/code editors. Its features: - Cross-platform (Windows, Mac, Unix) - Native API calls for faster screen access - Synchronous and asynchronous modes - Import and export of CSV data - Summary statistics, frequency distribution - Line/bar charts (including comparative ones) - Chart image export (with legend) Editor latency is delay between an input event and a corresponding screen update, in particular -- delay between keystroke and character appearance. While there are many kinds of delays (caret movement, line editing, etc.), typing latency is a major predictor of editor usability. Java 8 or later is required to run the program.
