Problems solved by technology

[0007] In this way, the user's gesture input device must be in a certain space to obtain the spatial position and rotation information, and to select objects. Long-term use will cause user hand fatigue
In addition, the rotation of the user's wrist will cause the gesture input device to shake, resulting in wrong selection, especially for the selection of long-distance, small, and dense target objects

Embodiment approach

[0064] The first way is to control the ray emitted from the handheld device by obtaining information such as the spatial position and direction of the handheld device. The virtual ray points to the target in the virtual space or within a certain area of ​​the target position (not pointing to the target), and then touches the ray on the handheld device with the thumb. Slide in the area, map the sliding trajectory in the target space as a visual cue, and the ray or trajectory will intersect with the target object to complete the target object selection. Wherein, the ray can move in the sliding direction or stay still. If sliding, the end of the ray is the end of the gesture sliding track. Implementation methods such as figure 2 shown.

[0065] The second method is to obtain information such as the spatial position and direction of the user's head-mounted display, and according to such information, control the rays emitted from the head, and the rays point to the target or a ce...

Abstract

The invention discloses a target selection method and system for virtual reality, and relates to the technical fields of virtual reality, augmented reality and mixed reality. The invention can help users select target objects in a virtual environment, especially far, small and dense objects The selection of objects can improve the speed and accuracy of object selection, and improve the comfort of users. The invention includes the following steps: using setting equipment to issue virtual rays pointing to the target area in the virtual environment. Obtain the sliding action of the specified part of the user's hand within the set touch area, and map the sliding action from the touch area to the target area as the sliding track of the virtual ray. In the target area, an object intersecting with the sliding track of the virtual ray is selected as the selected target object.

Description

technical field [0001] The invention relates to the technical fields of virtual reality, augmented reality and mixed reality, in particular to a method and system for selecting a target for virtual reality. Background technique [0002] Virtual reality, augmented reality, and mixed reality technologies can create virtual worlds, virtual objects, and enhance user experience. Users can interact with objects in the virtual environment through certain methods and systems. Object selection in a virtual environment is fundamental to interacting with that object. [0003] In the virtual reality system, the method of using the virtual ray controlled by the spatial position and direction of the hand-held controller to point the target, and then confirming the target object by pressing the button on the hand-held controller is the most advanced method in the current commercial head-mounted reality device. Commonly used object selection methods, such as the target selection method in ...
