Abstract

A control method includes responding to a first trigger event to control a screen to display a set three-dimensional (3D) cubic space region, responding to an operation on the set 3D cubic space region to obtain adjustment information of the set 3D cubic space region, adjusting the set 3D cubic space region based on the adjustment information to obtain an adjusted 3D cubic space region, and controlling the screen to display the adjusted 3D cubic space region.

First claim

What is claimed is:

1. A control method comprising:
responding to a first trigger event to control a screen to display a plurality of set three-dimensional (3D) cubic space regions;
responding to an operation on at least one set 3D cubic space region selected by a user from the plurality of set 3D cubic space regions to obtain adjustment information of the at least one set 3D cubic space region;
adjusting the at least one set 3D cubic space region based on the adjustment information to obtain at least one adjusted 3D cubic space region each corresponding to one of the at least one set 3D cubic space region;
controlling the screen to display the at least one adjusted 3D cubic space region; and
in response to determining that eyes are in the at least one adjusted 3D cubic space region, controlling the screen to be in a 3D display mode.

2. The method according to claim 1 , wherein responding to the operation on the at least one set 3D cubic space region to obtain the adjustment information of the at least one set 3D cubic space region includes:
responding to the operation on the at least one set 3D cubic space region to obtain relative movement information of an input object that performs the operation.

3. The method according to claim 2 , wherein responding to the operation on the at least one set 3D cubic space region to obtain the relative movement information of the input object that performs the operation includes:
responding to a movement operation on a first point, a first edge, or a first surface of the at least one set 3D cubic space region to obtain the relative movement information of the input object for adjusting a relevant portion of the first point, the first edge, or the first surface.

4. The method according to claim 1 , wherein responding to the operation on the at least one set 3D cubic space region to obtain the adjustment information of the at least one set 3D cubic space region includes:
responding to a volume adjustment operation on the at least one set 3D cubic space region to obtain the adjustment information corresponding to the volume adjustment operation, wherein the volume adjustment operation is performed to maintain a shape of the at least one set 3D cubic space region while adjusting a volume of the at least one set 3D cubic space region.

5. The method according to claim 1 , further comprising:
responding to a second trigger event on the at least one adjusted 3D cubic space region to control the screen to stop displaying the at least one adjusted three-dimensional cubic space region.

6. The method according to claim 1 , further comprising:
in response to determining that eyes are in a state of moving out of the at least one adjusted 3D cubic space region, controlling the screen to display an edge of the at least one adjusted 3D cubic space region in a set prompt method.

7. The method according to claim 6 , wherein in response to determining that the eyes are in the state of moving out of the at least one adjusted 3D cubic space region, controlling the screen to display the edge of the at least one adjusted 3D cubic space region in the set prompt method includes:
in response to determining that the eyes are in the state of moving out of the at least one adjusted 3D cubic space region, based on change information of a distance between the eyes and the edge of the at least one adjusted 3D cubic space region, controlling the screen to display the edge of the at least one adjusted 3D cubic space region in a set gradually changing prompt method.

8. The method according to claim 7 , wherein the set gradually changing prompt method includes at least one of a set color gradually changing prompt method or a set brightness gradually changing prompt method.

9. The method according to claim 8 , wherein based on change information of a distance between the eyes and the edge of the at least one adjusted 3D cubic space region, controlling the screen to display the edge of the at least one adjusted 3D cubic space region in the set gradually changing prompt method includes:
based on the change information of the distance between the eyes and the edge of the at least one adjusted 3D cubic space region, determining that the eyes being in a state of being close to the edge; and
at least one of:
controlling the screen to display the edge of the at least one adjusted 3D cubic space region in a prompt method of gradually changing from a first brightness to a second brightness, the second brightness being different from the first brightness; or
controlling the screen to display the edge of the at least one adjusted 3D cubic space region in the prompt method of gradually changing from a first color to a second color, the second color being different from the first color.

10. The method according to claim 6 , wherein controlling the screen to display the edge of the at least one adjusted 3D cubic space region in the set prompt method includes:
controlling the screen to display the edge of the at least one adjusted 3D cubic space region in a set color; and/or
controlling the screen to display the edge of the at least one adjusted 3D cubic space region in a set animation effect.

11. The method according to claim 1 , wherein responding to the operation on the at least one set 3D cubic space region to obtain the adjustment information of the at least one set 3D cubic space region includes:
responding to a shape adjustment operation on the at least one set 3D cubic space region to obtain the adjustment information corresponding to the shape adjustment operation, wherein the shape adjustment operation is performed to change a shape of the at least one set 3D cubic space region.

12. The method according to claim 1 , further comprising:
performing a same operation on the plurality of set 3D cubic space regions simultaneously.

13. An electronic device comprising:
a processor; and
a memory storing an instruction set that, when executed by the processor, causes the processor to:
respond to a first trigger event to control a screen to display a plurality of set three-dimensional (3D) cubic space regions;
respond to an operation on at least one set 3D cubic space region selected by a user from the plurality of set 3D cubic space regions to obtain adjustment information of the at least one set 3D cubic space region;
adjust the at least one set 3D cubic space region based on the adjustment information to obtain at least one adjusted 3D cubic space region each corresponding to one of the at least one set 3D cubic space region;
control the screen to display the at least one adjusted 3D cubic space region; and
in response to determining that eyes are in the at least one adjusted 3D cubic space region, control the screen to be in a 3D display mode.

14. The device according to claim 13 , wherein the instruction set further causes the processor to:
