Object picking device in three-dimensional display and object picking method in three-dimensional display

Abstract

The invention discloses a device for picking up an object in a three-dimensional display and a method for picking up an object in a three-dimensional display, wherein the device includes: a fixation point information acquisition module for acquiring position information of the fixation point of the current user's eyes relative to the user An object determination module, configured to determine the object picked up by the user according to the user's current position in the display space and motion posture information, the position information of the gaze point relative to the user, and the distribution information of the current object in the display space. The device and method of the present invention determine the object picked up by the user through the position of the gaze point of the eyes. The object picked up in the three-dimensional display space is natural and convenient, and the picking accuracy is high, and it is especially suitable for objects in the scene in the three-dimensional display space. Picking, still has good performance when the objects that can be picked up are dense.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display interaction, in particular to a device and method for picking objects in three-dimensional display. Background technique [0002] With the development of three-dimensional (3Dimension) display technology, the corresponding interaction methods and methods become more and more important. Selecting objects in 3D displayed content is an important step in interacting with 3D display technology. [0003] However, it is more difficult to select an object in three-dimensional space. One method is to require the user to move the position of himself (or a part of the body, such as a hand) to select. For some large scenes, the user needs a large range. It is very inconvenient to move your own position; another method is to pick up the desired object by selecting a direction. There are often multiple objects, and secondary selection from the multiple objects to obtain the object that you n...

[0003] However, it is more difficult to select an object in three-dimensional space. One method is to require the user to move the position of himself (or a part of the body, such as a hand) to select. For some large scenes, the user needs a large range. It is very inconvenient to move your own position; another method is to pick up the desired object by selecting a direction. There are often multiple objects, and secondary selection from the multiple objects to obtain the object you need to pick up will reduce the efficiency of object selection and the user experience is not good

[0004] In addition, taking the true 3D display based on the voxel (VolumetricPixel, also known as dynamic volume scanning) technology as an example, since the displayed 3D picture is formed by the rotation of the display surface, it is more difficult to select objects for interaction, and it is necessary to use a projection device to convert the image Direct object selection is only possible when projected outside the rotating display
