Embodiment Construction

[0073] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0074] The present invention proposes a solution to the "Midas Touch Problem", that is, the concept of a virtual interface. First, determine the size of the virtual interface through a learning process; then divide the virtual interface into partitions, each area represents a different function, and interact with the 3D virtual scene through the virtual interface; at the same time, the virtual interface will keep in sync with the human body, that is, when the human body moves to the left Or when moving a certain distance to the right, the virtual interface will also move accordingly to achieve the effect of keeping pace with the human body, so that the user can continue to operate in the original virtual interface. The experimental results show that the algorithm in this paper can efficiently solve the "Midas Touch Problem" and has a good user experience.

Abstract

The invention provides a gesture interaction method based on a virtual interface, and belongs to the field of man-machine interaction. The method includes the steps of firstly, segmenting a gesture, wherein a gesture image is separated out of a complex background, and the gesture part is reserved only in the foreground; secondly, establishing the virtual interface, wherein an operator draws a rectangular track in the air according to the left-to-right sequence and the bottom-to-top sequence, and conducts refitting according to the rectangular track to obtain the virtual interface; thirdly, partitioning the virtual interface, and judging the partition where a human hand is located; fourthly, refreshing and moving the virtual interface in real time, wherein when a human body moves, the generated virtual interface moves in the corresponding same direction while the human body moves.

Description

technical field [0001] The invention belongs to the field of human-computer interaction, and in particular relates to a gesture interaction method based on a virtual interface. Background technique [0002] As a natural way of interaction, gesture interaction has been paid more and more attention by people, and it is a research hotspot in the field of human-computer interaction. Compared with the traditional GUI-based interaction method, Vision-Based Gesture Interface (VBGI) enables users to get rid of the constraints of keyboard and mouse, thus becoming a natural and unconstrained interaction method. Vision-based gesture interface is widely used in many fields such as smart space, augmented reality, and pervasive computing, and has gradually become a research hotspot at home and abroad. However, because VBGI has the characteristics of non-contact and ambiguity, there is still a problem called "Midas Touch Problem". Since the effective range of human hand activities is oft...
