    Area of Science:

    • Computer Science
    • Human-Computer Interaction
    • Data Visualization

    Background:

    • Augmented reality (AR) 3D visualization is crucial for Big Data dissemination.
    • High spatial density in AR visualization presents challenges in object selection and interaction due to small targets and occlusion.
    • Existing techniques struggle with precise selection in complex, dense 3D environments.

    Purpose of the Study:

    • To introduce StarPicker, a multimodal progressive target selection technique for AR-based 3D Big Data visualization.
    • To address the limitations of current methods in handling high-density and small-target object selection.
    • To improve the accuracy and user satisfaction of target selection in AR environments.

    Main Methods:

    • Developed StarPicker, integrating SpotLight and Clock metaphors with wrist rotation and gesture interactions.
    • Implemented a coarse-to-fine semantic disambiguation for precise object selection.
    • Conducted a comparative user study evaluating StarPicker against GridWall and FlowerCone under high-density (360 objects) and small-target (1cm) conditions.

    Main Results:

    • StarPicker significantly outperformed baseline techniques in target selection accuracy and user satisfaction.
    • Completion times with StarPicker were comparable or better, particularly in denser scenes.
    • The technique demonstrated effectiveness in challenging high-density and small-target visualization scenarios.

    Conclusions:

    • StarPicker offers a novel and effective solution for target selection in AR-based 3D Big Data visualization.
    • The multimodal approach enhances interaction precision and user experience in complex visual environments.
    • This work advances AR interaction technologies for handling large-scale 3D datasets.
