SiouXtrack is a browser extension that allows the observation of user actions for ergonomic diagnosis. This extension, compatible with Chrome, records all user interactions with the web browser. It provides detailed information about user actions and the subsequent system reactions. From button clicks to text input and multimedia manipulation, SiouXtrack captures a wide range of user activities. It also records context changes, such as document opening/closing and window/tab manipulation.

Researchers and observers can access an interface within the browser preferences to customize the extension's settings. They can specify the types of events to be recorded, the level of detail to be captured, and the properties of web page elements to be memorized. Additionally, URL filtering allows users to create controlled experimental contexts, such as assigning specific tasks to participants.

The collected traces are transmitted to a server and stored in a database. Researchers can then analyze the data for statistical purposes, generate summaries of user journeys, and conduct individual protocol analyses. SiouXtrack's data can be used to characterize user behavior, diagnose navigation difficulties, and improve overall user experience.
