DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
The technical solutions of the embodiments of the disclosure will be described clearly and completely in conjunction with the figures herein. Obviously, the described embodiments are a part of the embodiments of the disclosure. A person skilled in the art can obtain other embodiments within the scope of the disclosure based on the embodiments herein.
A mobile terminal is provided according to embodiments of the disclosure.
FIG. 1 illustrates a mobile terminal according to an embodiment of the disclosure, comprising:
A display unit 11 configured to display an image to be displayed in 3D space beyond the mobile terminal;
A determination module 12 configured to determine an instruction input by a user in accordance with the displayed image through spatial position detection; and
A processing module 13 configured to execute an operation corresponding to the determined instruction.
Wherein the display unit 11 may display the image by Light Re-construction Technology (also referred to as Light Field Technology) or other technologies.
Also, the image displayed by the display unit 11 may be a preset-shaped planar interface and/or a preset-shaped solid graphical interface.
In a circumstance that the displayed image is the preset-shaped planar interface, if a target page to be displayed is determined in accordance with the instruction input by the user, the target page is displayed in the planar interface.
The target page to be displayed is determined in accordance with the instruction input by the user in the operation of the mobile terminal according to the embodiments of the disclosure, wherein the manners to input the instruction by the user include, but not limited to, a point touch manner and a sliding manner. Moreover, the image displayed by the mobile terminal according to the embodiments of the disclosure can be subjected to different operations such as point touch, sliding and the like by a hand (for example, fingers) or a touch pen and the like. The description is made with reference to the operation implemented by the user's fingers, and the technical solutions covered in the disclosure are also applicable to the operations implemented by the user in other manners.
In FIG. 2, the display unit 11 may display a primary menu 21 including a plurality of icons 21-1 (only two icons are illustrated in FIG. 2 for clarity) in the planar interface in an embodiment. When one icon in the primary menu 21 displayed by the display unit 11 is operated by the user's finger in a point touch manner, the mobile terminal can determine positions touched by the user's finger to further determine the icon operated by the user's finger (an executed operation); accordingly a secondary menu 22 is displayed in the planar interface. The secondary menu 22 can also include a plurality of icons, an entire picture, and combination thereof although not shown in FIG. 2. The secondary menu 22 may be a game picture and also an interface where a picture, a webpage, texts, a clock page, a navigation map and other applications to be browsed are operated.
In other embodiment, as shown in FIG. 3, the display unit 11 may display a primary menu 31 in a planar interface. When the user's finger slides in a region of the primary menu 31, the mobile terminal can determine motion trails of the user's finger so as to determine a sliding direction of the user's finger. If the current sliding direction of the user's finger corresponds to a page turning operation, a target page will be displayed, namely, the previous or next page 32 of the primary page 31. Similarly, the page 32 also includes a plurality of icons, an entire picture, and combination thereof. The page 32 may be a game picture and also an interface where a picture, a webpage, texts, a clock page, a navigation map and other applications to be browsed are operated.
Furthermore, the sliding direction of the user's finger may correspond to different orders, for example, the user's finger slides to the left and the right, which may be configured to correspond to page turning operations; the user's finger slides upwardly and downwardly, which may be configured to correspond to operations of backing to the previous menu and the main menu. Many configurations are not discussed in the description in detail.
Optionally, the planar interface may include, but not limited to, parallelogram, roundness, triangle, polygon and/or other planes pre-recorded by the mobile terminal.
Additionally, if a target page to be displayed is determined in accordance with the instruction input by the user and is not displayed in the solid graphical interface currently, the target page is displayed in a portion facing to the user currently within the solid graphical interface, alternatively, the target page is displayed in the solid graphical interface which is rotated so that the target page faces to the user in a circumstance that the displayed image is the preset-shaped solid graphical interface.
And, if a target page to be displayed is determined in accordance with the instruction input by the user and then displayed in the solid graphical interface currently, the solid graphical interface is rotated to face to the user in a circumstance that the displayed image is the preset-shaped solid graphical interface.
Optionally, the solid graphical interface may include, but not limited to, cube, sphere, solid triangle and/or other solid shapes (including irregular shapes) pre-recorded by the mobile terminal.
Taking a solid graphical interface of the cube for example, six surfaces of the cube may display different interfaces. For example, in an embodiment, under a condition that a page to be displayed is not displayed in the three-dimensional graphical interface, when the user's finger clicks an icon displayed on one surface where the page may display a plurality of icons/options, the next menu (i.e. the target page) the user will enter into after clicking the icon may be displayed in the current surface where the menu may display one or more instruction input box capable of receiving word and voice instructions input by the user. In another embodiment, when the user's finger clicks an icon displayed in one surface, the next menu the user will enter into after clicking the icon may be displayed in another surface, and the solid graphical interface is rotated so that the another surface where the next menu is displayed faces to the user.
For example, under a condition that the user clicks an icon A and a page X is the page to be displayed, if the page X is displayed on none of the six surface of the three-dimensional graphical interface, the page X is to be displayed on the surface where the icon A is positioned or other surface and thereby replace the originally displayed page.
Additionally, if the page to be displayed has been displayed in the three-dimensional graphical interface, the target page will be displayed by rotating the three-dimensional graphical interface.
In one embodiment, under a condition that the user clicks an icon B and a page Y is the page to be displayed, if the page Y has been displayed on the other surface of the three-dimensional graphical interface, the surface where the page Y is positioned faces to the user by rotating the three-dimensional graphical interface in response to the click executed by the user.
In another embodiment, the user can send an instruction for rotation of the three-dimensional graphical interface to rotate the three-dimensional graphical interface. In this case, when the user's finger slides in the graphical interface of the cube, the mobile terminal may determine a sliding direction of the user's finger (for example, the user's finger is detected to slide to the left and the right and slide upwardly and downwardly), and then the cube is rotated accordingly based on the directions. In an embodiment, if the plurality of surfaces of the cube can display a plurality of sub-pages in one menu, rotating the solid graphical interface of the cube is equal to execution of the page turning operation. In another embodiment, the plurality of surfaces of the cube displays not only a plurality of sub-pages in one menu but also the next or previous menu of the current menu. When the user's finger slides in the graphical interface of the cube and the solid graphical interface of the cube is rotated, both of the execution of the page turning operation and the execution of the back operation or the enter operation into the next menu are done. In another embodiment, the plurality of surfaces of the three-dimensional graphical interface are partially or completely configured to display the latest applications executed or latest pages browsed by the user.
Also, in some embodiments, the user can directly operate an icon displayed at each position within the solid graphical interface without rotation. In other embodiments, the mobile terminal may be preconfigured so that the mobile terminal merely identifies an operation to one or several portions in the solid graphical interface carried out by the user's finger, thereby avoiding error operation due to the larger size of the solid graphical interface.
Although the solid graphical interface of the cube is described, different-shaped solid graphical interfaces may be described similarly. For example, when the solid graphical interface is spherical, a spherical surface can be divided into several portions, wherein each portion is taken as a unit for displaying the primary menu or one page.
Furthermore, the mobile terminal according to embodiments of the disclosure further comprises an adjustment module (not shown) configured to regulate parameters of the displayed image, wherein the parameters include at least one of size, luminance, contrast ratio, shape and a distance from the image to the mobile terminal.
When the mobile terminal displays the planar interface, the user can operate to display the current contents in the solid graphical interface transferred from the planar interface; and the user may display the current contents in the planar interface transferred from the solid graphical interface, so that an image displayed in the solid graphical interface at any view is selected to be displayed in the planar interface. And, the transfers between different-shaped planar interfaces and different-shaped solid graphical interfaces may be implemented.
It means that the mobile terminal of the disclosure can transfer from the solid graphical interface to the planar interface. For example, when the user clicks one icon, or executes a page turning operation, or backs to the previous menu in the solid graphical interface, a target page to be entered may be a planar interface as needed; and when the user clicks one icon, or executes a page turning operation, or backs to the previous menu in the planar interface, a target page to be entered may be a solid graphical interface as needed.
In some embodiments, the size of the image displayed in 3D space and a distance between the image and the mobile terminal may be set by the adjustment module. For example, the size of the displayed image can be set to meet the user's requirement; and the distance between the displayed image and the mobile terminal may be also set.
In setting the size of the displayed image and the distance between the displayed image and the mobile terminal, the maximal/minimal size of the displayed image and the maximal/minimal distance between the displayed image and the mobile terminal both depend on performances of both the display unit and other components inside the mobile terminal, such as focal length of lens of the display unit, power consumption of the mobile terminal, and other factors. In some embodiments, the size of the image and the distance between the image and the mobile terminal may be set freely and may be set independently as well without departing from the scope of allowed performances of the mobile terminal.
In some embodiments, the size of the image may be scaled depending on the distance from the image to the mobile terminal. Optionally, in theses embodiments, the size of the image and the distance from the image to the mobile terminal can be preset at a plurality of levels for the user's selection. For example, refer to FIG. 4, the mobile terminal may display planar interfaces 41-43 in 3D space, and the size of the image is in direct proportion to the distance from the image to the mobile terminal. For example, the mobile terminal may display the planar interface 41 which has the minimal size and the closest distance from the mobile terminal; the mobile terminal also displays the planar interface 42 which has the size more than the size of the planar interface 41 and the distance from the mobile terminal more than the distance from the planar interface 41 to the mobile terminal; and the mobile terminal also displays the planer interface 43 which has the maximal size and the maximal distance from the mobile terminal.
Similarly, the size of the solid graphical interface is regulated, which is not discussed to avoid the repetition.
For example, in a practical application, an option required for the image displayed in the 3D space by the mobile terminal of the disclosure is selected in a ‘Touch’ operation manner, which may be realized by means of the determination module 12 having a distance measurement function to measure a 3D position of the user's finger in touch operation, the determination module 12 also comprising:
A detection sub-module (not shown) configured to detect spatial positions and/or motion trails of the finger in accordance with a distance between the finger and the mobile terminal; and
A determination sub-module (not shown) configured to determine an object operated by the user in the displayed image in accordance with a detection result from the detection sub-module, and determining an instruction input by the user in accordance with the object operated by the user. Wherein, the determination sub-module is capable of determining the object operated by the user by detecting the distance between the spatial position of the user's finger or the motion trails of the user's finger and the target (for example, the icon) in the displayed image.
In some embodiments, the detection sub-module may have two or more than two cameras, each camera having a camera-shooting and/or picture-taking function for determining the positions and/or motion trails of the finger. In one embodiment, the two or more than two cameras can be closer to each other at positions of the mobile terminal. In another embodiment, the two or more than two cameras can be farther to each other at positions of the mobile terminal. The two or more than two cameras can be ensured to acquire the positions of the finger at different angles so that the exact positions of the finger can be determined, thereby determining the object operated by the user in the displayed image.
Additionally, the mobile terminal of the disclosure may detect the positions and/or motion trails of the finger by other technologies, for example, the detection sub-module may be a laser positioning/distance-measuring component, and components to implement respective functions may be arranged in the mobile terminal flexibly as needed.
The following description is made with reference to two cameras which are taken as the detection sub-module to determine the positions of the finger. A person skilled in the art should recognize that utilization of more cameras or further measurement of motion trails of the finger can be implemented by the similar principle or other principles.
FIG. 5 illustrates spatial position detection of the finger executing the touch operation in 3D space. Position information obtained by the detection may realize the correct ‘Touch’ operation in the 3D space.
There are many ways to measure 3D space positions (distances) of the finger in the touch operation. In FIG. 5, distance measurement is implemented by utilizing two cameras (i.e., camera 1 and camera 2; more than 2 cameras can be used in the practical applications), comprising the following steps:
Step 1, using camera parameters to correct images;
Step 2, forming a correspondence between the images;
Step 3, generating parallax images, for example, by a triangle method principle, which means that image planes of the two cameras and the object to be measured form a triangle and a position correspondence between the two cameras is known so that a 3D coordinate of feature points of the object to be measured in a shared field of view of the two cameras may be obtained, thereby achieving the measurement, namely, generation of the parallax images; and
Step 4, calculating the distances (X, Y and Z).
The following description is made with reference to manners to detect positions of target points by the two cameras. In FIG. 6, when the objects to be detected are positioned at P1, P2 and P3, respectively, the objects to be measured are always positioned at mb in an image 1 displayed in the camera 1 due to P1, P2, P3 and an optical center 1 of the camera 1 being in a line. However, P1, P2 and P3 as well as an optical center 2 of the camera 2 are out of the line, so the measured object at P1 is positioned at ml in an image 2 acquired by the camera 2 according to the line between P1 and the optical center 2 when the camera 2 shoots the object at P1. Similarly, the measured object at P2 is positioned at m2 in an image 2 acquired by the camera 2 according to the line between P2 and the optical center 2, and the measured object at P3 is positioned at m3 in an image 2 acquired by the camera 2 according to the line between P3 and the optical center 2. Therefore, P1, P2 and P2 are in a line Lp for the camera 2, but each position point can be identified and determined clearly by combining the images acquired by the cameras 1 and 2. In other words, any position operated by the user can be determined. Specifically, an operation that a distance of the position of the finger away from one surface facing to the user in the planar interface or the three-dimensional interface is less than a threshold is considered as an operation of the user on the current interface.
The utilization of more cameras and the acquisition of motion trails of the user's finger by the cameras can be implemented by the similar principles.

In an embodiment, two or more than two cameras may be arranged at a position where the determination module 12 is positioned, as shown in FIG. 7. The two or more than two cameras are ensured not to be overlapped so that detection for the positions and/or motion trails of the finger can be implemented. In another embodiment, the two or more than two cameras can be arranged at a farther distance. In yet another embodiment, the detection sub-module may be a laser positioning/distance-measuring component. In other embodiment, the detection sub-module may be also other positioning/distance-measuring component; furthermore, any component for detecting the finger can be arranged flexibly as needed, for example, a plurality of cameras can be arranged at four corners of the display unit 11.
