虽然用半空中的手势操纵3D虚拟模型具有自然交互的好处，并且没有触摸表面的卫生问题，但许多因素可能会影响这种交互范例的可用性。在这项研究中，作者进行了实验，研究基于视觉的空中手势缩放，平移和旋转的3D虚拟汽车显示在一个大屏幕上。采用英特尔实感3D摄像头进行手势识别。双手手势与抓取，然后移动分开/接近对方被施加到放大/缩小的3D虚拟汽车。将单手抓取后移动的手势应用于汽车零部件的平移。采用双手抓取并沿水平圆的圆周沿着相对移动的手势来旋转汽车。十七名研究生被邀请参加实验，并提供他们的评价和意见的手势可用性。结果表明，检测范围的宽度和深度是影响线性运动双手手势可用性的关键因素。对于具有快速转换和从张开到闭合手部姿势的运动的动态手势，确保手势识别鲁棒性是极其重要的。此外，给定具有人体工程学姿势的手势，不适当的控制-响应比可能由于手势的重复用力而导致疲劳，以实现3D模型操作任务的精确控制。
Although manipulating 3D virtual models with mid-air hand gestures had the benefits of natural interactions and free from the sanitation problems of touch surfaces, many factors could influence the usability of such an interaction paradigm. In this research, the authors conducted experiments to study the vision-based mid-air hand gestures for scaling, translating, and rotating a 3D virtual car displayed on a large screen. An Intel RealSense 3D Camera was employed for hand gesture recognition. The two-hand gesture with grabbing then moving apart/close to each other was applied to enlarging/shrinking the 3D virtual car. The one-hand gesture with grabbing then moving was applied to translating a car component. The two-hand gesture with grabbing and moving relatively along the circumference of a horizontal circle was applied to rotating the car. Seventeen graduate students were invited to participate in the experiments and offer their evaluations and comments for gesture usability. The results indicated that the width and depth of detection ranges were the key usability factors for two-hand gestures with linear motions. For dynamic gestures with quick transitions and motions from open to close hand poses, ensuring gesture recognition robustness was extremely important. Furthermore, given a gesture with ergonomic postures, inappropriate control-response ratio could result in fatigue due to repetitive exertions of hand gestures for achieving the precise controls of 3D model manipulation tasks.
