本文研究了近体交互中精确空间操作的精细运动策略。我们与生俱来的精确工作能力是视觉-触觉感知、本体感觉和双手运动控制共同作用的结果。与此相反，大多数混合现实（MR）系统都是为臂长的交互而设计的。为了制定MR系统中精确操作的指南，需要对运动策略进行系统研究，包括物理索引、双手协调以及视觉和触觉反馈之间的关系。为了满足这一需求，我们提出了一系列的实验，使用三种变化的平板电脑为基础的MR接口，使用近距离运动捕捉系统和运动跟踪的形状代理。我们调查了一个精心制作的版本的经典钉孔任务，我们的研究结果强烈建议的关键需要高精度的跟踪，使精确的操作。
This paper studies fine motor strategies for precise spatial manipulation in close-to-body interactions. Our innate ability for precise work is the result of the confluence of visuo-tactile perception, proprioception, and bi-manual motor control. Contrary to this, most mixed reality (MR) systems are designed for interactions at arms length. In order to develop guidelines for precise manipulations in MR systems, there is a need for a systematic study of motor strategies including physical indexing, bi-manual coordination, and the relationship between visual and tactile feedback. To address this need, we present a series of experiments using three variations of a tablet-based MR interface using a close-range motion capture system and motion-tracked shape proxies. We investigate an elaborate version of the classic peg-and-hole task which our results strongly suggests the critical need for high precision tracking to enable precise manipulation.
