Torta: Generating Mixed-Media GUI and Command-Line App Tutorials Using Operating-System-Wide ...
summary
Torta automatically generates mixed-media tutorials by combining operating-system-wide tracing with screencast, bash hooks, keystroke and process logging to produce step-level file diffs, short screencap clips, and copyable terminal commands. An editor lets authors trim steps and add validation criteria; a web viewer shows clips, file diffs, and a validate and run button that spawns a terminal. Authors (10 CS TAs) prefer it to Google Docs and 6 student consumers all prefer Torta; it excels for code/sysadmin/data science but not binary apps like Photoshop.
