Virtual Hand with Ambiguous Movement between the Self and Other Origin: Sense of Ownership and 'Other-Produced' Agency

6.0K
While previous research on bodily self-consciousness assumed that self- and other-origin movements were perceptually distinguishable, this protocol allows them to be ambiguous on a virtual hand with unintentional slight movements. This enables us to observe one’s experience formed by SoO and other-produced SoA, rather than the absence of...

    Area of Science:

    • Human-Computer Interaction
    • Wearable Technology
    • Biomedical Engineering

    Background:

    • Traditional human-computer interaction methods can lead to repetitive strain injuries like carpal tunnel syndrome (CTS).
    • Existing gesture recognition systems often require complex setups or lack real-time responsiveness.

    Purpose of the Study:

    • To develop and evaluate a novel framework for real-time gesture recognition using pressure signals from a wearable device.
    • To assess the system's accuracy and usability for computer interaction and as a mouse replacement.

    Main Methods:

    • A prototype wearable gesture sensing device with four pressure sensors was developed.
    • An algorithmic framework incorporating innovative segmentation and recognition schemes was implemented.
    • A pressure-parameter adaptive updating strategy was employed for robustness.

    Main Results:

    • The system achieved a gesture recognition delay of approximately 100 ms.
    • Average accuracy reached 95.28% for experienced users and 86.20% for inexperienced users.
    • The system performed well in a mouse-controlling interaction task for both user groups.

    Conclusions:

    • Pressure-sensor based wristbands are effective for classifying hand gestures and enabling computer interaction.
    • The developed system offers a viable, interactive alternative to traditional mouse control.
    • This approach has the potential to mitigate the risk of developing carpal tunnel syndrome.
