Abstract

A local perspective method and device of a virtual reality equipment and a virtual reality equipment are disclosed. The local perspective method of a virtual reality equipment includes: detecting a user's hand gesture; displaying a real scene in a local perspective display area in a virtual scene according to a position of the user's hand gesture in response to that the user's hand gesture satisfies a preset trigger gesture; tracking the position of the user's hand gesture which satisfies the preset trigger gesture; and adjusting the local perspective display area in the virtual scene according to the position of the user's hand gesture.

First claim

What is claimed is:

1 . A local perspective method of a virtual reality equipment, comprising:
detecting a hand gesture of a user; determining whether the hand gesture satisfies a preset trigger gesture of trigging a local perspective function of the virtual reality equipment, wherein the local perspective function is configured to implement display of a real scene in a local perspective display area in a virtual scene based on determining the local perspective display area according to a position of the hand gesture; in response to determining that the hand gesture satisfies the preset trigger gesture, displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture, wherein the preset trigger gesture comprises a one-hand trigger gesture or a two-hand trigger gesture, and wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
generating a circular perspective display area in the virtual scene based on positions of an index finger and a thumb of the user's one-hand gesture, or
generating a triangular perspective display area in the virtual scene based on positions of two index fingers and two thumbs of the user's two-hand gesture;
tracking the position of the hand gesture and determining whether a change of the position is detected; and adjusting the local perspective display area in the virtual scene in response to detecting the change of the position of the hand gesture.

2 . The local perspective method according to claim 1 , wherein the hand gesture which satisfies the preset trigger gesture remains after the displaying the real scene.

3 . The local perspective method according to claim 1 , wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
in response to that the user's one-hand gesture satisfies the one-hand trigger gesture, determining the positions of the index finger and the thumb of the user's one-hand gesture.

4 . The local perspective method according to claim 1 , wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
in response to that the user's two-hand gesture satisfies the two-hand trigger gesture, determining the positions of the two index fingers and the two thumbs of the user's two-hand gesture.

5 . The local perspective method according to claim 1 , further comprising:
in response to that the hand gesture satisfies a preset turning-off gesture, turning off a local perspective function of the virtual reality equipment.

6 . The local perspective method according to claim 1 , wherein the triggering the local perspective function of the virtual reality equipment in response to determining that the hand gesture satisfies the preset trigger gesture comprises:
counting a duration of the hand gesture in response to that the hand gesture satisfies the preset trigger gesture, and triggering the local perspective function of the virtual reality equipment in response to that the duration of the hand gesture exceeds a preset time threshold, or counting number of times of performing the hand gesture in response to that the hand gesture satisfies the preset trigger gesture, and triggering the local perspective function of the virtual reality equipment in response to that the number of times of performing the hand gesture reaches a preset number of times of performing; and
determining the local perspective display area in the virtual scene to display the real scene in the local perspective display area according to the position of the hand gesture.

7 . A virtual reality equipment, comprising a processor and a memory for storing computer executable instructions, wherein the executable instructions upon execution by the processor cause the processor to implement operations comprising:
detecting a hand gesture of a user; determining whether the hand gesture satisfies a preset trigger gesture of trigging a local perspective function of the virtual reality equipment, wherein the local perspective function is configured to implement display of a real scene in a local perspective display area in a virtual scene based on determining the local perspective display area according to a position of the hand gesture; in response to determining that the hand gesture satisfies the preset trigger gesture, displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture, wherein the preset trigger gesture comprises a one-hand trigger gesture or a two-hand trigger gesture, and wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
generating a circular perspective display area in the virtual scene based on positions of an index finger and a thumb of the user's one-hand gesture, or
generating a triangular perspective display area in the virtual scene based on positions of two index fingers and two thumbs of the user's two-hand gesture;
tracking the position of the hand gesture and determining whether a change of the position is detected; and adjusting the local perspective display area in the virtual scene in response to detecting the change of the position of the hand gesture.

8 . The virtual reality equipment according to claim 7 , wherein the hand gesture which satisfies the preset trigger gesture remains after the displaying the real scene.

9 . The virtual reality equipment according to claim 7 , wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
in response to that the user's one-hand gesture satisfies the one-hand trigger gesture, determining the positions of the index finger and the thumb of the user's one-hand gesture.

10 . The virtual reality equipment according to claim 7 , wherein the displaying the real scene in the local perspective display area in the virtual scene based on the position of the hand gesture comprises:
in response to that the user's two-hand gesture satisfies the two-hand trigger gesture, determining the positions of the two index fingers and the two thumbs of the user's two-hand gesture.

11 . The virtual reality equipment according to claim 7 , wherein the operations further comprise:
in response to that the hand gesture satisfies a preset turning-off gesture, turning off a local perspective function of the virtual reality equipment.

12 . The virtual reality equipment according to claim 7 , wherein the triggering the local perspective function of the virtual reality equipment in response to determining that the hand gesture satisfies the preset trigger gesture comprises:
counting a duration of the hand gesture in response to that the hand gesture satisfies the preset trigger gesture, and triggering the local perspective function of the virtual reality equipment in response to that the duration of the hand gesture exceeds a preset time threshold, or counting number of times of performing the hand gesture in response to that the hand gesture satisfies the preset trigger gesture, and triggering the local perspective function of the virtual reality equipment in response to that the number of times of performing the hand gesture reaches a preset number of times of performing; and
determining the local perspective display area in the virtual scene to display the real scene in the local perspective display a
