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.
