In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
At present, users generally display contents through computers, and the display of the contents in VR scenes cannot be realized. To this end, in one embodiment of the present invention, a method and an apparatus for displaying content in a VR scene are provided, and the method may be applied to a processing device, for example: a computer or the like, the processing device being communicatively connected to the VR interaction device, and the VR interaction device may be provided with an inertial sensor, a position sensor, and the like, as shown in fig. 1 and 2, the method includes:
step S101, detecting whether contents to be displayed exist or not;
in this step, in one embodiment of the present invention, the content to be displayed that needs to be displayed at a certain display time may be stored in the storage space of the processing device, and when the display time comes, it is determined that the content to be displayed exists.
In another embodiment of the present invention, it may be determined whether acquisition content acquired by a data acquisition device is received; if the pre-stored content to be displayed exists or the collected content collected by the data collecting equipment is received, determining that the content to be displayed exists; otherwise, determining that the content to be displayed does not exist.
Step S102, if the content to be displayed exists, acquiring the content to be displayed;
step S103, determining a first virtual object used for displaying the content to be displayed in the VR scene;
in the embodiment of the invention, the user can specify the first virtual object through the VR interaction device, or can preset the first virtual object through a program.
And step S104, displaying the content to be displayed on the first virtual object.
In this step, the content to be displayed may be directly displayed on the first virtual object; or drawing a curve based on the content to be displayed and displaying the curve; or drawing a chart based on the content to be displayed and displaying the chart.
According to the embodiment of the invention, the content to be displayed can be displayed on the first virtual object of the VR scene, the data content is visualized, and a user can conveniently acquire the required data content in the VR scene.
In yet another embodiment of the present invention, as shown in fig. 3, the method further comprises:
after the content to be displayed is displayed on the first virtual object, acquiring the posture of VR interactive equipment;
in the embodiment of the present invention, the VR interaction device may refer to a motion capture glove, and the like, the motion capture glove may be worn on a hand of a user, and when the motion capture glove acquires a gesture of the hand of the user in a real scene, information including the gesture is sent to the processing device, so that the processing device acquires the gesture of the first motion capture glove.
For example, the first gesture may refer to a gesture of a user's hand, such as: open five fingers, grasp a fist, pinch the thumb and forefinger or pinch the thumb and middle finger, etc.
Determining, based on the gesture, a gesture in the VR scene that corresponds to the gesture;
in this step, a gesture matching the gesture is generated in the VR scene, and for example, the gesture may be the same as the gesture; the corresponding positions in a plurality of important positions and the first gesture can be the same, other non-important positions are similar to the gestures, and the important positions can refer to key points of preset hand gesture collection positions, such as fingertips, palm centers and the like.
Judging whether the gesture is a preset disappearing control gesture for controlling the disappearing of the content to be displayed and displayed on the first virtual object;
for example, the preset disappearing control gesture may be a five-finger opening gesture, a fist making gesture, or the like, in this step, the gesture may be compared with the preset disappearing control gesture, and if the similarity between the two gestures is greater than a preset similarity threshold, the gesture may be determined to be the preset disappearing control gesture.
And if the gesture is the preset disappearing control gesture, controlling the content to be displayed on the first virtual object to disappear.
According to the embodiment of the invention, the real content to be displayed on the first virtual object can be controlled to disappear according to the posture of the VR interactive device, and the content to be displayed can not be displayed on the first virtual object any longer through interaction with the VR scene when the user does not need to continuously display the content to be displayed by the first virtual object.
In a further embodiment of the present invention, as shown in fig. 4 and 5, the method further comprises:
determining an alignment line in a VR scene corresponding to the alignment gesture;
to facilitate alignment, a straight line perpendicular to the palm in the alignment gesture may be determined as an alignment line; or, for more accuracy in alignment, an extension line of the wrist in the alignment gesture may be determined as an alignment line; or, in order to reduce the angle of wrist lifting in the alignment process, a line connecting the center of the palm and the centers of circles formed by three preset finger tips in the alignment gesture can be determined as the alignment line.
And if the alignment line is aligned with a second virtual object after the first virtual object is aligned, controlling the content to be displayed to be transferred from the first virtual object to the second virtual object for display.
In this step, firstly, the user may make the alignment line pass through the first virtual object in the VR scene, and after the hand gesture of the user changes, the alignment line determined according to the gesture corresponding to the gesture correspondingly passes through the second virtual object, so that it may be determined that the alignment line aligns with the second virtual object after aligning with the first virtual object. Furthermore, it may be considered that the user needs to transfer the content to be displayed on the first virtual object to the second virtual object for display, and therefore, the processing device controls the content to be displayed to be transferred from the first virtual object to the second virtual object for display.
In embodiments of the invention, the visible light emitting assembly on the motion capture glove can be controlled to emit visible light along the alignment line when the virtual object is aligned, the visible light forming a beam of light in its path of travel, which can facilitate determining whether the alignment line passes through the virtual object.
According to the embodiment of the invention, the content to be displayed, which needs to be displayed on the first virtual object by the user, can be transferred to the second virtual object to be displayed according to the change of the hand gesture of the user, so that the operation is simple, and the use by the user is convenient.
