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 ...

Embodiment Construction

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0042] The interactive process of the inventive method is as figure 1As shown, from the perspective of user input, it includes two major operations: calibration operation and confirmation operation; and from the perspective of system output, it includes two major feedbacks: highlight feedback and result feedback. The user performs the calibration operation to complete the input, and the computer collects and processes the input data and informs the user of the currently selected object (set) through the highlighted object. After multiple interaction cycles, the user finally selects the target object, and the calibration process ends. Calibration and highlight feedback complement each other in th...
