Description

TECHNICAL FIELD

The present application relates to the field of communications, and in particular, to content sharing methods and apparatuses.

BACKGROUND

With development of technologies, new display devices such as near-to-eye display devices (for example, smart glasses) and transparent screens constantly emerge, and users have more abundant and more convenient content display ways. However, compared with the traditional mobile devices (for example, smart phones and tablet computers), although the new display devices have advantages of great field of vision, being easy to wear and the like, the new display devices still have some disadvantages in aspects such as screen resolution and display effects (color saturation, brightness and contrast); while the traditional mobile devices have developed for several years, and display effects, pixel density thereof and the like have reached a higher level. Therefore, making full use of respective advantages of the traditional mobile devices and the new devices to perform display interaction and content sharing between the two kinds of devices will provide greater convenience for users.

Generally, sharing local content in which a user is interested in display content from a display device A to a display device B comprises the following steps: 1) establishing a communication connection between the device A and the device B; 2) sending, by the device A, the display content to the device B; 3) receiving, by the device B, the display content; and 4) obtaining, by the user, a region of interest through a corresponding operation (for example, zoom or take a screenshot) on the device B. The process has tedious steps, takes more time and has poor user experience.

DETAILED DESCRIPTION

Example embodiments of the present application are described in detail hereinafter with reference to the accompanying drawings and embodiments. The following embodiments are intended to describe the present application, but not to limit the scope of the present application.

It should be understood by those skilled in the art that, in the embodiments of the present application, the value of the serial number of each step described above does not mean an execution sequence, and the execution sequence of each step should be determined according to the function and internal logic thereof, and should not be any limitation to the embodiments of the present application.

FIG. 1 is a flowchart of the content sharing method according to one embodiment of the present application. The method may be implemented on, for example, a content sharing apparatus. As shown in FIG. 1, the method comprises:

S120: determining position information of a projection region of a second display region of a second display device on a first display region of a first display device relative to at least one eye of a user; and

S140: acquiring related information of the projection region from the first display device according to the position information.

The content sharing method according to this embodiment of the present application determines position information of a projection region of a second display region of a second display device on a first display region of a first display device relative to at least one eye of a user, and then acquires related information of the projection region from the first display device according to the position information, that is to say, a user can acquire content of interest from the first display device only by adjusting the position of the first display device or the second display device to cause the projection region to cover the content of interest, thereby simplifying content sharing steps, improving content sharing efficiency and enhancing user experience.

The functions of steps S120 and S140 will be described below in detail in combination with example embodiments.

S120: Determine position information of a projection region of a second display region of a second display device on a first display region of a first display device relative to at least one eye of a user.

The at least one eye may be one eye (the left eye or the right eye) of the user, or may be two eyes (the left eye and the right eye) of the user. Description will be given below according to two situations of one eye and two eyes respectively. The first display region and the second display region may be real display regions or virtual display regions.

Firstly, in the situation of one eye, in one example embodiment, step S120 may comprise:

S120′: determining position information of a projection region of the second display region on the first display region relative to one eye of the user.

Referring to FIG. 2, the projection region 230 is a region formed by points of intersection between connecting lines from one eye 240 of the user to the second display region 220 and the first display region 210. As light enters the eye 240 through a pupil 241, it may also be said that the projection region 230 is a region formed by points of intersection between connecting lines from a pupil 241 of one eye 240 of the user to the second display region 220 and the first display region 210. In addition, the one eye may be the left eye or the right eye; their principles are the same, and will not be described respectively.

By taking FIG. 2 as an example, the projection region 230 may also be understood as a region corresponding to projection formed by convergent light emitted by a light source located on a first side of the second display region 220 on the first display region 210 located on a second side of the second display region 220. The convergent light converges into a point at the pupil 241 of the one eye 240, and the first side is a side opposite to the second side.

Referring to FIG. 3, in one example embodiment, step S120′ may comprise:

S121′: determining the position of the one eye;

S122′: determining the position of the first display region; and

S123′: determining the position information of the projection region of the second display region on the first display region relative to the one eye according to the position of the one eye and the position of the first display region.

In step S121′, an image of the one eye can be acquired, and then the position of the one eye is determined through image processing.

In step S122′, an image of the first display region can be acquired, and then the position of the first display region is determined through image processing. Alternatively, the position of the first display region may also be acquired through communication with the first display device, for example, in one example embodiment, in FIG. 2, four vertices E, F, G and H of the first display region 210 can send visible light information respectively, and the position of the first display region 210 can be determined according to the visible light information.

By still taking FIG. 2 as an example, in step S123′, suppose that the position of the first display region 210 has been determined, a projection point A′ of a vertice A of the second display region 220 on the first display region 210 (that is, a point of intersection between a connecting line from the vertice A to the eye 240 (or the pupil 241) and the first display region 210) can be computed and determined according to the position of the one eye 240 (or the pupil 241). Similarly, projection points B′, C′ and D′ corresponding to vertices B, C and D of the second display region 220 can be obtained, and the projection region 230 can be obtained by connecting the four projection points A′, B′, C′ and D′. Position information of the projection region 230 may be coordinate information of the four projection points A′, B′, C′ and D′.

In addition, in the above example embodiments, the first display region 210 is located between the eye 240 and the second display region 220, but the present application is not limited to the position relation. Referring to FIG. 4, in the event that the second display region 220 is located between the eye 240 and the first display region 210, the projection region of the second display region 220 on the first display region 210 relative to the one eye 240 may also be determined according to the position of the first display region 210 and the position of the one eye 240; the principle thereof is similar to the above example embodiments, which is no longer described individually.

Then, in the situation of two eyes, in one example embodiment, step S120 may comprise:

S120″: determining position information of a projection region of the second display region on the first display region relative to two eyes of the user.

Referring to FIG. 5, in the example embodiment, the projection region is associated with a left eye projection region and a right eye projection region. The left eye projection region is a region formed by points of intersection between connecting lines from the left eye 550 of the user to the second display region 520 and the first display region 510. The right eye projection region is a region formed by points of intersection between connecting lines from the right eye 560 of the user to the second display region 520 and the first display region 510. As light enters eyes through pupils, it may also be said that the left eye projection region 531 is a region formed by points of intersection between connecting lines from the left pupil 551 of the left eye 550 of the user to the second display region 520 and the first display region 510; and the right eye projection region 532 is a region formed by points of intersection between connecting lines from the right pupil 561 of the right eye 560 of the user to the second display region 520 and the first display region 510.

Referring to FIG. 6, in one example embodiment, step S120″ may comprise:

S121″: determining the position of the left eye and the position of the right eye of the user respectively;

S122″: determining the position of the first display region;

S123″: determining a left eye projection region of the second display region on the first display region relative to the left eye and a right eye projection region of the second display region on the first display region relative to the right eye according to the position of the left eye, the position of the right eye and the position of the first display region; and

S124″: determining the position information of the projection region of the second display region on the first display region relative to the two eyes according to the left eye projection region and the right eye projection region.

In step S121″, images of the left eye and the right eye can be acquired respectively, and then the position of the left eye and the position of the right eye are determined respectively through image processing.

In step S122″, an image of the first display region can be acquired, and then the position of the first display region is determined through image processing. Alternatively, the position of the first display region may also be acquired through communication with the first display device, for example, suppose that, in FIG. 5, the first display region 510 is rectangular, four vertices E, F, G and H of the first display region 510 can send visible light information respectively, and the second display device can determine the position of the first display region 510 according to the visible light information.

By still taking FIG. 5 as an example, in step S123″, suppose that the position of the first display region 510 has been determined, a projection point A′ of a vertice A on the first display region 510 (that is, a point of intersection between a connecting line from the vertice A to the right eye 560 (or the pupil 561) and the first display region 510) can be computed and determined according to the position of the right eye 560 (or the pupil 561). Similarly, projection points B′, C′ and D′ corresponding to vertices B, C and D can be obtained, and the right eye projection region 532 can be obtained by connecting the four projection points A′, B′, C′ and D′. The above steps are repeated for the left eye 550, and the left eye projection region 531 can be obtained.

In step S124″, the projection region finally determined may comprise the left eye projection region 531 and the right eye projection region 532, or the projection region finally determined may only comprise an overlapping region of the left eye projection region 531 and the right eye projection region 532.

In addition, in the above example embodiments, the first display region 510 is located between the eyes (the left eye 550 and the right eye 560) and the second display region 520, but the present application is not limited to the position relation. In the event that the second display region 520 is located between the eyes and the first display region 510, the method of the present application may also be implemented according to the same principle, which is no longer described individually herein.

S140: Acquire related information of the projection region from the first display device according to the position information.

The related information of the projection region may comprise: display content of the projection region. The display content may be an image, a map, a document, an application window or the like.

Alternatively, the related information of the projection region may comprise: display content of the projection region, and associated information of the display content. For example, if the display content of the projection region is a local map of a certain city, the associated information may comprise views of different enlarged scales of the local map. Thus, the user can perform a zooming operation on the local map on the second display device.

Alternatively, the related information of the projection region may comprise: coordinate information of the projection region. For example, if a local map of a certain city is displayed in the projection region, the coordinate information is coordinate information (that is, latitude and longitude information) of two diagonal vertices of the local map, and according to the coordinate information, the second display device can take a screenshot of the local map on a map stored locally and display the local map to the user.

Referring to FIG. 7, in one example embodiment, step S140 may comprise:

S141′: sending the position information to the first display device; and

S142′: receiving the related information of the projection region sent by the first display device according to the position information.

By taking FIG. 5 as an example, in step S141′, coordinates of four projection points A′, B′, C′ and D′ can be sent to the first display device, and the first display device can determine the projection region in the first display region according to the coordinates of the four projection points A′, B′, C′ and D′ and then feeds back related information of the projection region.

Referring to FIG. 8, in another example embodiment, step S140 may comprise:

S141″: receiving related information of the first display region sent by the first display device; and

S142″: determining the related information of the projection region according to the position information and the related information of the first display region.

In the previous example embodiment, the first display device determines the related information of the projection region according to the related information of the first display region and the position information; the example embodiment is different from the previous example embodiment in that, the execution body of the method, for example, the content sharing apparatus, previously receives related information of the entire first display region, and then computes and determines the related information of the projection region in combination with the position information. In comparison, the previous example embodiment is conducive to reducing network traffic, but the first display device is to have certain computation capability; the example embodiment is applicable to the situation where the first display device has weaker computation capability.

In addition, in order to make the user enjoy a better display effect, resolution of the second display device may be higher than that of the first display device.

In addition, the embodiment of the present application further provides a computer readable medium, comprising a computer readable instruction that performs the following operations when being executed: executing the operations of step S120 and S140 of the method in the example embodiment shown in FIG. 1.

To sum up, according to the method in the embodiment of the present application, position information of a projection region of a second display region of a second display device on a first display region of a first display device relative to at least one eye of a user can be determined, and related information of the projection region is acquired from the first display device according to the position information, thus simplifying an operation step of sharing a part of display content on the first display device to the second display device, improving content sharing efficiency and enhancing user experience.

The content sharing apparatus 900 may be disposed on the second display device as a functional module.

The functions of the determination module 910 and the acquisition module 920 will be described below in detail in combination with example embodiments.

By still taking FIG. 5 as an example, suppose that the position of the first display region 510 has been determined, the third determination unit 913″ can compute and determine a projection point A′ of a vertice A on the first display region 510 (that is, a point of intersection between a connecting line from the vertice A to the right eye 560 (or the pupil 561) and the first display region 510) according to the position of the right eye 560 (or the pupil 561). Similarly, projection points B′, C′ and D′ corresponding to vertices B, C and D can be obtained, and the right eye projection region 532 can be obtained by connecting the four projection points A′, B′, C′ and D′. Likewise, the left eye projection region 531 can be obtained.

The projection region that can be finally determined by the fourth determination unit 914″ comprises the left eye projection region 531 and the right eye projection region 532, or the projection region finally determined only comprises an overlapping region of the left eye projection region 531 and the right eye projection region 532.

Thus, the user can perform a zooming operation on the local map on the second display device.

Alternatively, the related information of the projection region may comprise: coordinate information of the projection region.
