Overhead bare-handed three-dimensional target selection method based on half-contour highlight

Abstract

The invention discloses an overhead bare-handed three-dimensional target selection method based on half-contour highlight. The method comprises the steps: (1) a preparation stage: a system presents ascene to a user, and configures a half-contour shielding model for each candidate object; (2) a calibration highlight feedback stage: a dynamic calibration method based on cone rays is adopted for selecting four or less than four objects as alternative sets for confirmation selection, and half-contour highlight feedback is carried out on the objects; and (3) confirmation result feedback stage: theuser executes a corresponding selection confirmation gesture operation according to different highlight forms of different objects, and then the system obtains a confirmation intention of the user according to analysis and recognition of the gesture, matches the confirmation intention with a corresponding highlight object and gives feedback of a selection result to the user. By utilizing the method, the user can accurately express the selection intention through inaccurate operation, and the selection performance of the object and the user experience are improved.

Description

technical field [0001] The invention belongs to the technical field of human-computer interaction, and in particular relates to a volley freehand three-dimensional target selection method based on semi-contour highlighting. Background technique [0002] Target object selection technology is one of the core technologies in human-computer interaction. In human-computer interaction, before operating on the target object, it needs to be selected first. With the emergence of new interaction modes, natural human-computer interaction has entered people's field of vision. Gesture interaction, as one of the important modes, has become a research hotspot. Due to its wide application value, it has become a research hotspot in 3D human-computer interaction. [0003] Among them, volley freehand interaction is considered to be the "mouse" of the next interactive era. Through the volley freehand mode, users can use gestures to communicate with the computer and realize the interaction of ...

AI Technical Summary

Problems solved by technology

[0005] However, in the volley freehand 3D selection method, due to the ambiguity of the volley freehand mode-users are accustomed to fuzzy operations, it is difficult for the computer to recognize the user's operation intention

Specifically, it is mainly manifested in the fact that at the device layer, the accuracy of hand data acquisition by the bare-handed data acquisition device is limited; at the interaction layer, the Heisenberg effect, that is, when the user confirms the selection, the hand operation will cause unexpected shaking , resulting in the failure to select the target object; in the user layer, the hand will shake unconsciously during the volley operation

[0006] It is precisely because of the gap between the imprecise input from the three levels of user, device and interaction and the precision required by the 3D selection task itself, which affects the accuracy of 3D target selection
