Natural control 3D gesture interface and system facing hierarchical information

Abstract

The present invention discloses a natural control 3D gesture interface facing hierarchical information. The novel 3D gesture interface is constructed facing a hierarchical information structure in a computer system. A 3D radiation tree display mode of a 3D gesture interface hierarchical space is combined with gesture motion data acquired by gesture acquisition equipment and parametric virtual hand shapes are used for defining a uniform gesture model so as to construct a set of gesture instructions for natural control of the hierarchical information of the computer system and implement the interactive response. According to the natural control 3D gesture interface facing the hierarchical information provided by the present invention, the hierarchical information structure through gestures can be effectively managed, accommodating the natural gesture behavior of people, which is convenient to understand, labor-saving, and simple to implement.

Description

technical field [0001] The invention relates to a gesture interaction interface, in particular to a 3D gesture interface and system for natural manipulation of hierarchical information. Background technique [0002] With the development of technology, the interface is becoming more and more simple, and it is difficult to provide a better interactive experience with two-dimensional operation. 3D technology simulates the environment of real life. To reduce learning costs and have a better experience, the user interface in many fields is gradually converted to 3D, and 3D technology has developed rapidly. [0003] Although 3D technology has been developed rapidly, there is currently no method for displaying hierarchical information structures such as file systems and menus in computers. Fumas and Card et al. pointed out that when users interactively explore large-scale visual information, they tend to maintain the visibility of the overall view of the information while explorin...

AI Technical Summary

Problems solved by technology

[0003] Although 3D technology has been developed rapidly, there is currently no method for displaying hierarchical information structures such as file systems and menus in computers.

[0005] Hierarchical data requires users to constantly search for target nodes or perform corresponding operations on target nodes. For these operations, traditional interaction methods often require hardware devices such as auxiliary keyboards, mice, and control pens. Users fail to free their hands. And poor environmental adaptability

The introduction of multi-touch technology makes the human-computer interaction represented by touch screen more convenient and natural, but the way of multi-touch screen is limited to the operation of the user's hands on a two-dimensional specific plane, and the user still cannot leave the hardware device and The size of the device is limited, and it has not really achieved a natural and free human-computer interaction effect

At the same time, due to the addition of one-dimensional information in the 3D interface display form, on the one hand, the authenticity and immersion are greatly improved; on the other hand, it also makes the traditional interaction method and touch screen method more inapplicable
