    Area of Science:

    • Medical Technology
    • Human-Computer Interaction
    • Surgical Innovation

    Background:

    • Sterile environments in operating rooms are critical, yet traditional interfaces pose contamination risks.
    • Advancements in natural user interfaces (NUIs) offer potential for safer human-machine interaction in complex settings.
    • Existing operating table controls can be cumbersome and increase infection hazards.

    Purpose of the Study:

    • To develop and evaluate a novel, touchless operating table control system for sterile environments.
    • To assess the usability and safety of a gesture-based interface for manipulating surgical equipment.
    • To reduce the risk of contamination associated with traditional operating table controls.

    Main Methods:

    • Implementation of a 3D sensor system (Microsoft Kinect) for motion capture.
    • Development of a gesture recognition algorithm for touchless control of motorized operating table segments.
    • Conducting a usability study with 15 participants to evaluate the system's effectiveness and user experience.

    Main Results:

    • The touchless system demonstrated intuitive and safe manipulation of the operating table via three distinct gestures.
    • Gesture dynamics were successfully synchronized with table movements, ensuring fluid control.
    • The system achieved a high System Usability Scale score of 79 in a usability study, indicating strong user acceptance.

    Conclusions:

    • The proposed gesture-controlled operating table system offers a significant improvement in usability and safety for sterile environments.
    • This touchless interface has high potential for implementation in interventional settings, reducing contamination risks.
    • Future applications may extend to controlling even higher-risk processes, enhancing safety and directness of interaction.
