Area of Science:

Medical Informatics
Human-Computer Interaction
Surgical Technology

Background:

Surgeons require rapid, efficient, and safe access to information during procedures.
Sterile environments necessitate hands-free interaction with computer systems.
Current systems often lack integration for comprehensive data management and recording.

Purpose of the Study:

To develop and evaluate "MedNav," a comprehensive operating room information system.
To address the need for hands-free control and data management in surgical settings.
To integrate Health Level 7 (HL7) and Digital Imaging and Communications in Medicine (DICOM) standards.

Main Methods:

Development of an integrated operating room information system (MedNav).
Implementation of a natural user interface (NUI) with touch-less finger and hand tracking.
Testing of a prototype system in a live operating room environment.
Conducting contextual interviews and usability satisfaction questionnaires.

Main Results:

The MedNav system successfully integrates HL7 and DICOM standards.
Touch-less NUI allows for practical and safe interaction during surgery.
The system enables automatic recording of procedural data and multi-perspective visualization.
Usability testing confirmed the system's usefulness in streamlining data and workflow.

Conclusions:

Integration of systems into a comprehensive solution maximizes surgical team usefulness.
MedNav provides a quick, practical, and harmless method for collecting and visualizing medical information.
The touch-less NUI management tool enhances efficiency and safety in the operating room.
