During the last two decades, development of 3D object selection techniques has been widely studied because it is critical for providing an interactive virtual environment to users. Previous techniques encounter difficulties with selecting small or distant objects, as well as naturalness and physical fatigue. Although eye-hand based interaction techniques have been promoted as the ideal solution to these problems, research on eye-hand based spatial interaction techniques in 3D virtual spaces has progressed very slowly. We propose a natural and efficient spatial interaction technique for object selection, which is motivated by understanding the human grasp. The proposed technique, gaze–grasp pose interaction (GG Interaction), has many advantages, such as quick and easy selection of small or distant objects, less physical fatigue, and elimination of eye-hand visibility mismatch. Additionally, even if an object is partially overlapped by other objects, GG Interaction enables a user to select the target object easily. We compare GG Interaction with a standard ray-casting technique through a formal user study (participants \(=\) 20) across two scenarios. The results of the study confirm that GG Interaction provides natural, quick and easy selection for users.

GG交互：用于3D虚拟对象选择的凝视-笔势姿势交互

在过去的二十年中，由于3D对象选择技术的发展对于为用户提供交互式虚拟环境至关重要，因此已经得到了广泛的研究。先前的技术在选择较小或较远的物体以及自然度和身体疲劳方面遇到困难。尽管基于眼手的交互技术已被推广为解决这些问题的理想方法，但是在3D虚拟空间中基于眼手的空间交互技术的研究进展非常缓慢。我们提出了一种自然而有效的空间交互技术来进行对象选择，这是通过了解人类的掌握来激发的。提出的技术，凝视-笔势姿势交互（GG Interaction）具有许多优点，例如可以快速轻松地选择较小或较远的物体，较少的身体疲劳，并消除了手眼可见度不匹配的情况。另外，即使一个对象被其他对象部分重叠，GG Interaction也使用户能够轻松选择目标对象。通过正式的用户研究，我们将GG Interaction与标准的射线投射技术进行了比较（参与者\（= \） 20）在两种情况下。研究结果证实，GG Interaction为用户提供了自然，快速和轻松的选择。
