Abstract: Current gesture interaction technologies are not satisfactory to perform 2D interaction tasks, since they are developed for 3D interactions. To solve this problem, this paper presents a new 3D gesture interaction technique to emulate a mouse function for 2D interactions. Based on the ISO9241-9 standard, a multi-directional tapping test for controlling typical 2D interactions is developed to evaluate the performance by comparing the 3D gesture interaction method with the general 3D gesture interaction method and the mouse interaction method in three aspects： the standard throughput, pointing-selection time and error rate. After that, a survey is conducted by users to evaluate the satisfactory scores of the proposed method. The results show that the proposed method can perform 2D interaction tasks by achieving higher accuracy, better controlling experiences, and without reducing the throughput rate than the general 3D gesture interaction method.

摘要： 针对当下3D手势交互在执行2D交互任务时用户体验不佳，提出了一种模拟鼠标2D交互方式的3D手势交互技术。根据ISO9241-9标准，设计多方向点选实验，用于比较该3D手势交互技术、一般3D手势交互技术和日常鼠标这三种交互技术在执行典型2D交互任务时的标准吞吐量、指向-选择时间和错误率。以调查问卷的方式评估该交互技术的主观舒适性。结果显示，与一般的手势交互相比，在不降低吞吐率的情况下，该交互技术在执行2D交互任务时可以获得更高的准确率以及更好的舒适度体验。
