Device and method for picking object in three-dimensional display

Abstract

The invention discloses a device and method for picking up an object in three-dimensional display. The device comprises a fixation point information acquisition module and an object determining module, wherein the fixation point information acquisition module is used for obtaining information of the position, relative to a user, of the fixture point of the eyes of the user, and the object determining module is used for determining an object to be picked up by the user according to current position and moving posture information of the user in display space, the information of the position, relative to the user, of the fixture point and distribution information of current object in the display space. The device and method determine the object to be picked up by the user through the position of the fixture point of the eyes and are high in pick-up accuracy, and the object in the three-dimensional display space is picked up naturally and conveniently, The device is particularly suitable for picking up objects in occasions with large scenes in the three-dimensional display space and still has good performance when the objects allowing pick-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 (3 Dimension) 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 ...

[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 (Volumetric Pixel, 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. Direct object selection is possible only when the image is projected outside the rotating display device
