通过手的直接操纵是重要的，因为它允许用户在沉浸式虚拟现实环境中容易地操纵3D虚拟对象。虽然直接的手操纵易于理解并且易于用于近似定位，但是它被认为不适合于对沉浸式环境中的虚拟对象进行精确调整，因为难以将无支撑的手保持在半空中，然后在固定点处释放对象。因此，本文提出了自动调整的方法，以准确地定位和释放虚拟对象。这些方法是位置调整、虚拟手大小调整、视点调整和释放调整。这些调整的组合使用户能够准确地操纵虚拟对象。实验结果表明，释放调整显著提高了任务完成率和对小目标的主观偏好。
Direct manipulation by hand is important in that it allows users to manipulate 3D virtual objects easily in an immersive virtual reality environment. Although direct hand manipulation is easy to understand and easy to use for approximate positioning, it has been considered unsuitable for making precise adjustments to virtual objects in an immersive environment because it is difficult to hold an unsupported hand in midair and then release an object at a fixed point. This paper therefore proposes automatic methods of adjustment to position and release virtual objects precisely. These methods are position adjustment, virtual hand size adjustment, viewpoint adjustment, and release adjustment. Combinations of these adjustments enable users to accurately manipulate virtual objects. Experimental evaluation revealed that release adjustment significantly increased the completion ratio for tasks and subjective preference for small targets.
