Lamprey is a new tool for analyzing user behavior on biomedical websites. It tracks web sessions to evaluate user interfaces without altering existing software, providing detailed insights into navigation patterns.

Area of Science:

  • Biomedical Informatics
  • Human-Computer Interaction
  • Web Analytics

Background:

  • Understanding user behavior is crucial for optimizing web-based information systems.
  • Evaluating the usability of biomedical information interfaces requires detailed user interaction data.
  • Existing methods may not capture the full context of user navigation.

Purpose of the Study:

  • To introduce Lamprey, a novel tool for quantitative and qualitative analysis of web-based user interfaces.
  • To enable comprehensive evaluation of user interaction with biomedical information systems.
  • To provide a method for retaining full user session data for detailed analysis.

Main Methods:

  • Lamprey functions as a centralized filter, rerouting World Wide Web (WWW) navigation.

  • It collects the sequence and timing of hyperlink usage for individual users.
  • The tool is implemented as a standard Common Gateway Interface (CGI) application.
  • Lamprey requires no modifications to client or server software and is browser-compatible.

    • Main Results:

    • Lamprey successfully captures detailed user session data, including navigation sequences and timing.
    • The tool facilitates both quantitative and qualitative assessments of web interface usability.
    • It provides a complete record of user interactions, enabling session recreation.
    • Demonstration shows effective evaluation of web usage patterns.

    Conclusions:

    • Lamprey offers a robust and non-intrusive method for analyzing user behavior on biomedical websites.
    • The tool enhances the evaluation of web-based user interfaces by preserving full session details.
    • Lamprey supports the optimization of biomedical information systems through detailed usage pattern analysis.
