Remote pointing is an input method that involves in-air gesticulation. Target selection via Leap Motion-based remote pointing and mouse-based pointing were compared while addressing methodological limitations that were present in previous studies. Participants completed the ISO 9241-9 multidirectional tapping test for pointing device evaluation with a wide range of target size-distance combinations and a standardized arm posture. Dependent variables included movement time, errors, throughput, perceived comfort, perceived fatigue, user preference, and perceived usability. Leap Motion-based input led to (a) worse user productivity, (b) more finger, wrist, shoulder, and neck fatigue, (c) lower preference ratings, and (d) lower usability ratings than mouse-based input. The experiment (i) confirmed findings about remote pointing-related productivity and fatigue, and did so while controlling methodological limitations present in prior studies, (ii) revealed significant discomfort and fatigue despite the presence of an arm rest, and (iii) revealed new findings about preference and usability.

远程指向是一种涉及空中手势的输入方法。比较了通过基于Leap Motion的远程指向和基于鼠标的指向进行的目标选择，同时解决了先前研究中存在的方法学局限性。参与者完成了针对指向设备评估的ISO 9241-9多向攻丝测试，该目标设备具有多种目标尺寸-距离组合和标准化的手臂姿势。因变量包括移动时间，错误，吞吐量，感知的舒适度，感知的疲劳，用户喜好和感知的可用性。与基于鼠标的输入相比，基于Leap Motion的输入导致（a）用户工作效率降低；（b）手指，手腕，肩膀和颈部的疲劳加剧；（c）偏好等级较低；以及（d）可用性等级较低。
