Abstract:

Leap Motion gesture recognition has an unstable recognition phenomenon at the edge of recognition area and the occlusion of finger. This paper proposes a Leap Motion gesture interaction level correction method. The method analyzes the recognition error of Leap Motion by real-time contrast threshold method, and uses the layered correction algorithm to correct the position of the human hand and solve the identification instability phenomenon in the process of human interaction. Through the analysis of the experiment, 75% participants are satisfied with the experimental interaction, 80% participants believe that the method is more accurate, and the recognition accuracy of the interactive content exceeds 89%, which fully proves that the method can improve the recognition accuracy and improve the user experience of Leap Motion.

Key words: Human-Computer Interaction（HCI）, Leap Motion, hierarchical movement, user study
