Systems and methods for providing an audio-guided virtual reality tour

1. A system for providing an audio-guided in-door virtual reality (VR) tour, comprising:

a communication interface configured to receive input from a user and to output media contents;

a memory storing computer-readable instructions; and

at least one processor coupled to the communication interface and the memory, wherein the computer-readable instructions, when executed by the at least one processor, cause the at least one processor to perform operations comprising:

displaying, through the communication interface, a view of a three-dimensional (3D) VR environment;

playing, through the communication interface, an audio guide associated with the view;

during the playing of the audio guide, automatically altering the view by playing back a sequence of pre-recorded spatial operations to manipulate a field of view (FOV) for observing the 3D VR environment, wherein the playing back of the sequence of the pre-recording spatial operations is in synchronization with the playing of the audio guide;

detecting, during the playing of the audio guide, a target operation input by the user to further alter the view that is being automatically altered;

in response to the detection of the target operation, adjusting, based on the detected target operation, the view with respect to a fixed point position within the 3D VR environment, wherein the fixed point position is within a first functional space of the 3D VR environment and adjusting the view by changing to any other point position is not allowed;

detecting, during the playing of the audio guide, an operation input by the user to change, in virtual reality, the view from the first functional space to a second function space that is different from the first functional space; and

in response to the detection of the operation, sending, through the communication interface, an alert indicating the operation is not permitted because of the playing of the audio guide.

2. The system of claim 1 , wherein the fixed point position corresponds to a first point position at which the view is displayed when the target operation is detected.

3. The system of claim 1 , wherein the fixed point position corresponds to a first point position at which the view is captured by a VR image capturing device.

4. The system of claim 1 , wherein:

the target operation comprises altering the FOV for observing the 3D VR environment; and

the operations comprise displaying, based on the FOV, the adjusted view observed at the fixed point position.

5. The system of claim 4 , wherein the target operation comprises at least one of a sliding operation, a zooming-in operation, or a zooming-out operation.

6. The system of claim 1 , wherein the operations comprise:

displaying, through the communication interface, an audio guide control associated with the audio guide on a launching page of the audio-guided in-door VR tour, the launching page comprising an image associated with the audio-guided in-door VR tour;

receiving, through the communication interface, an instruction from the user triggering the audio guide control; and

in response to the reception of the instruction, automatically playing the audio guide and displaying the view of the 3D VR environment associated with the audio guide.

7. The system of claim 6 , wherein the audio guide control comprises at least one of an image of an audio guide narrator, a description of the audio guide, or a play button.

8. A method for providing an audio-guided in-door virtual reality (VR) tour, comprising:

displaying, through a communication interface, a view of a three-dimensional (3D) VR environment;

playing, through the communication interface, an audio guide associated with the view;

during the playing of the audio guide, automatically altering the view by playing back a sequence of pre-recorded spatial operations to manipulate a field of view (FOV) for observing the 3D VR environment, wherein the playing back of the sequence of the pre-recording spatial operations is in synchronization with the playing of the audio guide;

detecting, during the playing of the audio guide, a target operation input by a user to further alter the view that is being automatically altered;

in response to the detection of the target operation, adjusting, based on the detected target operation, the view with respect to a fixed point position within the 3D VR environment, wherein the fixed point position is within a first functional space of the 3D VR environment and adjusting the view by changing to any other point position is not allowed;

detecting, during the playing of the audio guide, an operation input by the user to change, in virtual reality, the view from the first functional space to a second function space that is different from the first functional space; and

in response to the detection of the operation, sending, through the communication interface, an alert indicating the operation is not permitted because of the playing of the audio guide.

9. The method of claim 8 , wherein the fixed point position corresponds to a first point position at which the view is displayed when the target operation is detected.

10. The method of claim 8 , wherein the fixed point position corresponds to a first point position at which the view is captured by a VR image capturing device.

11. The method of claim 8 , wherein:

the target operation comprises altering the FOV for observing the 3D VR environment; and

the method comprises displaying, based on the FOV, the adjusted view observed at the fixed point position.

12. The method of claim 11 , wherein the target operation comprises at least one of a sliding operation, a zooming-in operation, or a zooming-out operation.

13. The method of claim 8 , comprising:

displaying, through the communication interface, an audio guide control associated with the audio guide on a launching page of the audio-guided in-door VR tour, the launching page comprising an image associated with the audio-guided in-door VR tour;

receiving, through the communication interface, an instruction from the user triggering the audio guide control; and

in response to the reception of the instruction, automatically playing the audio guide and displaying the view of the 3D VR environment associated with the audio guide.

14. The method of claim 13 , wherein the audio guide control comprises at least one of an image of an audio guide narrator, a description of the audio guide, or a play button.

15. A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method for providing an audio-guided in-door virtual reality (VR) tour, the method comprising:

displaying, through a communication interface, a view of a three-dimensional (3D) VR environment;

playing, through the communication interface, an audio guide associated with the view;

during the playing of the audio guide, automatically altering the view by playing back a sequence of pre-recorded spatial operations to manipulate a field of view (FOV) for observing the 3D VR environment, wherein the playing back of the sequence of the pre-recording spatial operations is in synchronization with the playing of the audio guide;

detecting, during the playing of the audio guide, a target operation input by a user to further alter the view that is being automatically altered;

in response to the detection of the target operation, adjusting, based on the detected target operation, the view with respect to a fixed point position within the 3D VR environment, wherein the fixed point position is within a first functional space of the 3D VR environment and adjusting the view by changing to any other point position is not allowed;
