Description

TECHNICAL FIELD

Embodiments of the present invention relates to the field of man-machine interaction technologies, and in particular, to an interaction method and apparatus for electronic devices.

BACKGROUND

With the rapid development of electronic technologies, electronic devices have been diversified, such as notebook computers, tablet computers, smart phones, and e-books. An electronic device usually provides a good man-machine interface on which a user may use multiple input manners, such as a manner of using a mouse, key board, or touch screen to perform operations. A display apparatus of an electronic device displays corresponding operation results to a user.

In the prior art, an electronic device usually provides indexes of contents that a user needs to browse in the form of a thumbnail list or word list. When the user needs to browse the detailed content of an object in the list, the user needs to click the object. The electronic device then displays corresponding detailed information of this object for the user by opening a new page. After checking the details, the user needs to close this detail page or return to the previous list. In this way, the user needs to frequently open and close pages that display detailed information or perform return operations, which causes low browsing efficiency.

To overcome technology flaws in the foregoing method, the prior art further provides another method, where an electronic device displays list information and detailed information simultaneously for a user. However, due to restriction from display space, the display effect is poor.

SUMMARY

Embodiments of the present invention provide an interaction method and apparatus for electronic devices to improve interaction effects of electronic devices.

An embodiment of the present invention provides an interaction method for electronic devices, including:

generating a visual interface, where the visual interface includes at least two different display areas;

detecting a current hot spot and determining a display area corresponding to the current hot spot as a hot spot display area; and

stretching the hot spot display area along a direction of a display area other than the hot spot display area.

An embodiment of the present invention provides an interaction apparatus for electronic devices, including:

an interface generation unit, configured to generate a visual interface, where the visual interface includes at least two different display areas;

a hot spot detection unit, configured to detect a current hot spot and determine a display area corresponding to the current hot spot as a hot spot display area; and

an area stretching unit, configured to stretch the hot spot display area along a direction of a display area other than the hot spot display area.

As can be seen from the foregoing technical solutions, in the interaction method and apparatus for electronic devices provided in the embodiments of the present invention, a visual interface including at least two different display areas is generated, a display area corresponding to a current hot spot is determined as a hot spot display area, and the hot spot display area is stretched along a direction of a display area other than the hot spot display area. This increases display space of the display area a user is paying attention to and may display content of the hot spot display area in more details. The user can stretch the display area the user is paying attention to only by changing the current hot spot instead of performing open and close operations frequently, thereby improving interaction effect of electronic devices.

DESCRIPTION OF EMBODIMENTS

The following clearly describes the technical solutions in embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

Embodiment 1

FIG. 1 is a flowchart of an interaction method for electronic devices in Embodiment 1 of the present invention. As shown in FIG. 1, the interaction method for electronic devices provided in the embodiment of the present invention may be used for but not limited to man-machine interactions of electronic devices. The interaction method for electronic devices may be executed by a control apparatus of an electronic device and implemented in the form of hardware and software.

The interaction method for electronic devices provided in this embodiment includes the following steps:

Step 10: Generate a visual interface, where the visual interface includes at least two different display areas.

Each display area may be specifically used to display different content, or one display area therein is used to display a thumbnail list or a word list, while at least one of other display areas is used to display corresponding information of an object on the list.

Step 20: Detect a current hot spot and determine a display area corresponding to the current hot spot as a hot spot display area.

The current hot spot may be specifically a motion track of a mouse left on a screen or a finger movement of a user using a touch screen. The display area where the current hot spot resides is taken as the hot spot display area, indicating that attention focus of the user is on the display area.

Step 30: Stretch the hot spot display area along a direction of a display area other than the hot spot display area.

The stretching the hot spot display area along a direction of a display area other than the hot spot display area may be specifically stretching the hot spot display area in horizontal, vertical, or diagonal direction. The implementation manner may be set according to layout of each display area on the visual interface. When the hot spot display area is stretched, display space and display content of the display area other than the hot spot display area may remain unchanged. The stretched hot spot display area partially covers other display areas. The display area other than the hot spot display area may also be dimmed to highlight the hot spot display area. The display area other than the hot spot display area may further contract as the hot spot display area is stretched.

Content displayed after the hot spot display area is stretched may be detailed information or relative information of content displayed before stretching. If the content displayed before the hot spot display area is stretched is an image, the content displayed after stretching may be an enlarged image or a clearer image of a high resolution. The content displayed in the display area and in the stretched hot spot display area may be set according to actual content display requirements and is not limited by the embodiment of the present invention.

In the interaction method for electronic devices provided in this embodiment, a visual interface including at least two different display areas is generated, a display area corresponding to a current hot spot is determined as a hot spot display area, and the hot spot display area is stretched along a direction of a display area other than the hot spot display area. This increases display space of the display area the user is paying attention to and may display the content of the hot spot display area in more details. The user can stretch the display area the user is paying attention to only by changing the current hot spot instead of performing open and close operations frequently, thereby improving interaction effect of electronic devices.

In this embodiment, when step 30 is performed to stretch the hot spot display area along the direction of the display area other than the hot spot display area, the hot spot display area partially covers the display area other than the hot spot display area. At this time, the display area other than the hot spot display area may remain unchanged. The display area other than the hot spot display area may also be dimmed to highlight the hot spot display area.

In this embodiment, only the hot spot display area needs to be stretched, and the display area other than the hot spot display area may remain unchanged, that is, after each display area in the visual interface is stretched and the current hot spot falls on a display area, it is only required to place the display area on other display areas. When the current hot spot switches from a display area to another, the display area that is stretched before may automatically restore to its initial size.

In this embodiment, when step 30 is performed to stretch the hot spot display area along the direction of the display area other than the hot spot display area, step 40 may be simultaneously performed to compress the display area other than the hot spot display area along a stretching direction of the hot spot display area. When the hot spot display area is stretched, the display area other than the hot spot display area is compressed correspondingly so that the display areas do not overlap.

In this embodiment, specifically, a compressed display area is attached to a boundary or a corner of a stretched display area as a label. The hot spot display area may be stretched to occupy display space of the whole visual interface, presenting for the user in a maximum display form. At this time, the compressed display area is attached to the boundary or corner of the stretched display area as a label. When the current hot spot falls on the label, the label may be restored to an original display area and be stretched.

Embodiment 2

An interaction method for electronic devices provided in this embodiment is a specific implementation manner of Embodiment 1.

In this embodiment, the stretching the hot spot display area along a direction of a display area other than the hot spot display area in step 30 may specifically include:

gradually increasing the length and the width of the hot spot display area to a first preset length and a second preset width, respectively, to stretch the hot spot display area.

In this embodiment, the compressing the display area other than the hot spot display area along a stretching direction of the hot spot display area in step 40 may specifically include:

gradually reducing the length and the width of the display area other than the hot spot display area to a second preset length and a second preset width, respectively, to compress the display area other than the hot spot display area.

In this embodiment, when the at least two display areas are stretched or compressed, displayed content in each display area is dynamically zoomed in or out as the display areas are stretched or compressed; or the displayed content in each display area is dynamically increased or decreased as the display areas are stretched or compressed.

In this embodiment, the dynamically increasing or decreasing the displayed content in the at least two display areas as the display areas are stretched or compressed may specifically include the following steps:

invoking a content object corresponding to each of the at least two display areas respectively and displaying content of the content object in the corresponding display area, where, specifically, the content of the content object may be dynamically generated according to background information, and when the interaction method for electronic devices provided in the embodiment of the present invention is applied to Web page interaction, a Javascript object may be used as the content object.

FIG. 2 is a flowchart of an interaction method for electronic devices in Embodiment 2 of the present invention. As shown in FIG. 2, a specific process of the interaction method for electronic devices provided in this embodiment may be as follows:

Step 10: Generate a visual interface, where the visual interface includes at least two different display areas.

Step 20: Detect a current hot spot and determine a display area corresponding to the current hot spot as a hot spot display area.

Step 31: Gradually increase the length and the width of the hot spot display area to a first preset length and a second preset width, respectively.

Step 41: Gradually reduce the length and the width of the display area other than the hot spot display area to a second preset length and a second preset width, respectively.

Step 51: Invoke a content object corresponding to the at least two display areas respectively and display content of the content obj ect in the corresponding display area.

It should be noted that step 31 and step 41 are executed simultaneously, and are not subject to a specific time sequence during execution.

Embodiment 3

An interaction method for electronic devices provided in this embodiment is another specific implementation manner of Embodiment 1.

In this embodiment, after step 10 is performed to generate a visual interface, where the visual interface includes at least two different display areas and before step 20 is performed to detect a current hot spot and determine a display area corresponding to the current hot spot as a hot spot display area, the following steps may be further included:

Step 60: Divide the visual interface into at least two underlying operating areas, where each display area at least covers one underlying operating area.

The dividing the visual interface into at least two underlying operating areas is specifically division of a physical interface of the visual interface. The total display area of all the underlying operating areas is the display area of the visual interface. For example, if the display area of the visual interface is 900 pixel×600 pixel and the visual interface is divided into three underlying operating areas, the display area of each underlying operating area is 300 pixel×600 pixel.

Step 70: Assign a grade to each of the underlying operating areas.

The stretching the hot spot display area along a direction of a display area other than the hot spot display area in step 30 may specifically include the following steps:

Step 301: Acquire a highest grade of an underlying operating area in the hot spot display area as an attention grade.

Step 302: Acquire at least one underlying operating area as an auxiliary area, where the underlying operating area is neighboring to the hot spot display area and with a grade lower than the attention grade.

Step 303: Combine the hot spot display area and the auxiliary area.

Through acquiring at least one underlying operating area as an auxiliary area, where the underlying operating area is neighboring to the hot spot display area and with a grade lower than the attention grade, and combining the hot spot display area and the auxiliary area, the hot spot display area is stretched. The display area other than the hot spot display area may remain unchanged or be compressed by subtracting the auxiliary area when the auxiliary area used for combination is an underlying operating area included in one or more display areas in the display area other than the hot spot display area.

FIG. 3 is a flowchart of an interaction method for electronic devices in Embodiment 2 of the present invention. As shown in FIG. 3, a specific process of the interaction method for electronic devices provided in the embodiment of the present invention may be as follows:

Step 10: Generate a visual interface, where the visual interface includes at least two different display areas.

Step 60: Divide the visual interface into at least two underlying operating areas, where each display area at least covers one underlying operating area.

Step 70: Assign a grade to each of the underlying operating areas.

Step 20: Detect a current hot spot and determine a display area corresponding to the current hot spot as a hot spot display area.

Step 301: Acquire a highest grade of an underlying operating area in the hot spot display area as an attention grade.

Step 302: Acquire at least one underlying operating area as an auxiliary area, where the underlying operating area is neighboring to the hot spot display area and with a grade lower than the attention grade.

Step 303: Combine the hot spot display area and the auxiliary area.

Embodiment 4

In this embodiment, at least two different display areas may include a first display area and a second display area. The first display area is used to display at least one marked graph, where the marked graph is used to indicate specified content. The second display area is used to display brief information of at least one marked graph in the first display area. If the first display area is a hot spot display area, the second display area displays brief information of a marked graph in the first display area. If the second display area is the hot spot display area, the brief information displayed in the second display area is unfolded into detailed information. The marked graph may be in icon form or in text form. The first display area may be a list area including multiple marked graphs. The second display area may be brief information corresponding to a marked graph in the list area.

The following example uses a Web page as an example to specifically describe the interaction method for electronic devices provided in the embodiment of the present invention.

FIG. 4 is a schematic operation diagram for Web page interaction in Embodiment 4 of the present invention. As shown in FIG. 4, a visual interface is generated. The visual interface may be specifically a Web page displayed in a browser. The visual interface includes two display areas with D1 as the first display area and D2 as the second display area. The first display area D1 and the second display area D2 are laterally distributed. The first display area D1 displays multiple marked graphs, and the second display area D2 displays brief information of a marked graph displayed in the first display area D1. Initial content of the second display area D2 may be brief information of a first marked graph in the first display area D1. The brief information may include specifically a contracted form of an image and brief text description. A user may choose to click a marked graph in the first display area D1 to display its corresponding brief information in the second display area D2.

When the user needs to browse detailed information of the marked graph, the user switches a current hot spot to the second display area D2 (step 111) and stretches the second display area D2 along a direction of the first display area D1. The brief information displayed in the second display area D2 is unfolded into detailed information. The detailed information may include specifically an enlarged form of an image and detailed text description. At this time, the size and content of the first display area D1 remain unchanged. The second display area D2 is presented to the user by partially covering the first display area D1.

After the user completes browsing the detailed information in the second display area D2, the user switches the current hot spot to the first display area D1 (Step 112). Because the size and content of the first display area D1 remain unchanged when the second display area D2 is stretched, the first display area D1 may be directly displayed as a top layer, and at this time, the second display area D2 may be restored to its initial state and display brief information.

The stretching the second display area D2 may be implemented by using the method provided in Embodiment 2, that is, increasing the length and the width of the second display area D2 to a first preset length and a second preset width. The second display area D2 may also be stretched using the method provided in Embodiment 3. FIG. 5 is a schematic diagram for underlying operating area division in Embodiment 4 of the present invention. As shown in FIG. 5, the visual interface may be divided into three underlying operating areas from left to right. The three underlying operating areas are respectively a first underlying operating area, a second underlying operating area, and a third underlying operating area. In initial state, the first display area D1 includes the first and second underlying operating areas, and the second display area D2 includes the third underlying operating area. The grade of the first underlying operating area is A, the grade of the second underlying operating area is B, and the grade of the third underlying operating area is A. When the user switches the current hot spot to the second display area D2, the second display area D2 acquires and is combined with the second underlying operating area to stretch the second display area D2.
