头戴式增强现实(AR)使得能够以三维(3D)体现原位绘图。我们探索3D绘图交互的基础上,无仪器,不受阻碍(裸)的手,保留用户的能力,自由地浏览和与物理环境进行交互。我们从文献和分析几个设想的用例中得出三种替代的交互技术,支持在AR中徒手绘图。这三种交互技术进行了评估,在一个控制的用户研究检查三个不同的绘图任务:平面绘图,路径描述,和3D对象重建。结果表明,连续手绘支持更快的线创建比控制点为基础的替代品,虽然精度降低。用户对不同技术的偏好是混合的,在不同的任务之间有很大的差异,突出了多样化和灵活的交互的价值。这三种绘图技术的组合效果在3D AR绘图的示例应用中示出。
Head-mounted augmented reality (AR) enables embodied in situ drawing in three dimensions (3D). We explore 3D drawing interactions based on uninstrumented, unencumbered (bare) hands that preserve the user's ability to freely navigate and interact with the physical environment. We derive three alternative interaction techniques supporting bare-handed drawing in AR from the literature and by analysing several envisaged use cases. The three interaction techniques are evaluated in a controlled user study examining three distinct drawing tasks: planar drawing, path description, and 3D object reconstruction. The results indicate that continuous freehand drawing supports faster line creation than the control point based alternatives, although with reduced accuracy. User preferences for the different techniques are mixed and vary considerably between the different tasks, highlighting the value of diverse and flexible interactions. The combined effectiveness of these three drawing techniques is illustrated in an example application of 3D AR drawing.
