Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present invention are proposed.
A first embodiment of the present invention provides a method for displaying a double-sided screen, and referring to fig. 3, fig. 3 is a schematic flow chart of the first embodiment of the method for displaying a double-sided screen according to the present invention, where the method for displaying a double-sided screen includes:
step S10, acquiring image data of a target object when receiving a display instruction based on the target object;
with the continuous development of intelligent terminals, different manufacturers try to release various innovations, wherein the appearance of a double-screen mobile phone indicates unprecedented mobile phone experience. As the name implies, a mobile phone has two screens, generally speaking, one screen of the mobile phone is a common screen, and the other screen of the mobile phone is a screen adopting an electronic ink technology. Of course, according to different requirements, the double-sided screen is not limited to the screen made of two different materials, but can be the screen made of the same material, for example, an electronic screen is adopted.
Receiving a display instruction based on a target object, and determining whether touch operation corresponding to the display instruction meets a target object display condition; and when the touch operation of the display instruction is determined to meet the display condition of the target object, acquiring the image data of the target object. The specific form of the display instruction may be preset by the system, or may also be user-defined, and may be specifically set according to an actual situation, which is not limited in the embodiment of the present invention. The display condition of the target object is a condition that the display instruction needs to be satisfied effectively. For example, the display instruction may be a long-press touch operation on the target object, when the terminal screen detects a touch operation of the user based on the target object, it is determined whether a touch duration of the touch operation meets a preset touch duration of the display instruction, and when the preset touch duration is met, it is determined that the touch operation meets the display condition of the target object.
A step S20 of generating front side data and back side data based on the image data;
when the image data of the target object is acquired, determining the holding angle of the current double-sided screen terminal; and processing the image data into front data and back data according to the holding angle.
In this embodiment, the holding angle of the dual-screen terminal can be determined by a gravity sensor and a gyroscope, the purpose of determining the holding angle is to determine which screen of the terminal faces the user, and if the user faces the first display screen, the first display screen displays the front data of the target object; if the user is facing the second display screen, the back data of the target object is displayed on the front side of the actual object, and the front data, that is, the data displayed on the first display screen is displayed on the back side of the actual object. For example, after receiving a display instruction, the terminal needs to display three-dimensional image data of a human body, the user is oriented to the back side of the terminal, and after the terminal acquires the image data of the human body, the front side of the human body is processed into back side data for displaying on the second display screen, and the back side of the human body is processed into front side data for displaying on the first display screen. In general, the terminal determines which display screen of the user is oriented toward the user according to the grip angle, and displays the front of the three-dimensional stereoscopic image data to the user. The front data and the back data correspond to the first display screen and the second display screen, and no matter what the specific image content is, the front data is displayed in the first display screen, and the back data is displayed in the second display screen.
The important step of processing an image into front data and back data is to divide the complete three-dimensional data into two parts, one of which is to simply mark the image data after the image data is acquired and distinguish the front data from the back data according to the mark points. The other mode is based on artificial intelligence, and a model or a network is trained through a large amount of marked data, so that the neural network has the capability of distinguishing the front data from the back data, and the corresponding front data and back data can be obtained after any image data is input.
And step S30, displaying the front data of the target object through a first display screen, and displaying the back data of the target object through a second display screen.
Acquiring a first display parameter corresponding to a first display screen, adjusting front data based on the first display parameter, and displaying the front data in the first display screen; and acquiring a second display parameter corresponding to a second display screen, adjusting reverse data based on the second display parameter, and displaying the reverse data in the second display screen.
Further, in an embodiment, before step S10, the method further includes:
and establishing image data of the target object in a preset mode, and storing the image data according to the specified path.
The image data of the target object can be obtained in various ways, for example, the image data of the object to be displayed can be obtained by shooting, the target object can be shot based on different angles to obtain a plurality of photos, and the photos are synthesized into three-dimensional stereo data through a later image processing means. Three-dimensional image data of a target object can also be directly generated through computer software, for example, after the design requirements of related products are acquired, a mathematical model is established based on a product modeling technology.
The virtual design technology is a comprehensive system technology formed by multidisciplinary advanced knowledge, and is essentially based on a simulation technology supported by a computer, the whole process of product development and the influence of the whole process on product design are simulated in real time and in parallel at the product design stage, and the product performance, the product manufacturing cost, the product manufacturability, the product maintainability, the product detachability and the like are predicted, so that the one-time success rate of product design is improved. It is also beneficial to more effectively, economically and flexibly organizing manufacturing production, so that the design and layout of factories and workshops are more reasonable and more effective, and the development period and the cost of products are minimized, the design quality of the products is optimized, and the production efficiency is maximized.
In the double-sided screen display method provided in the embodiment, when a display instruction based on a target object is received, image data of the target object is acquired; then generating front data and back data based on the image data; then, displaying the front data of the target object through a first display screen, and displaying the back data of the target object through a second display screen; the method can make full use of the characteristics of the double-sided screen, reasonably and fully display the target object by combining the interactive characteristics of the two screens, simultaneously provides a flexible switching mode, and improves the user experience.
Based on the first embodiment, a second embodiment of the double-sided screen display method of the present invention is provided, and referring to fig. 4, after step S30, the method further includes:
step S40, receiving a slide operation entered on the first display screen or the second display screen;
in this embodiment, the first display screen and the second display screen are respectively disposed on two sides of the mobile terminal and fixedly connected to each other through a frame structure of the mobile terminal. The first display screen and the second display screen only represent two different display screens and have no essential difference. In practice, one of the first display screen and the second display screen is a main screen, that is, a screen on the front side of the terminal, which is a screen mainly used by a user at ordinary times, and the other is a screen on the back side of the terminal.
First display screen and second display screen are the screen of touch-sensitive, when detecting that the user carries out the sliding operation in above-mentioned screen, can acquire information such as the slip direction, sliding distance and the slip orbit of this sliding operation.
Step S50, determining whether the sliding operation meets a preset switching condition;
determining whether the sliding direction of the sliding operation is a preset direction; or determining whether the sliding distance of the sliding operation exceeds a preset distance threshold; or determining whether the sliding operation is the sliding operation input by at least 2 fingers on a preset area of the first display screen or the second display screen. The preset direction may be a sliding direction such as leftward sliding, rightward sliding, upward sliding, downward sliding, and the like, and may be set according to an actual situation, which is not limited in the present invention. In the embodiment of the present invention, the preset distance threshold may be a sliding distance of 2cm, 3cm, and the like, and may be specifically set according to an actual situation, which is not limited in the present invention. In the embodiment of the present invention, the sliding direction and the sliding distance of the sliding operation may be obtained according to the starting point of the sliding operation and the direction and the distance between the terminals sensed by the touch sensing function of the display screen when the sliding operation is entered, and are not described again. In a preferred embodiment of the present invention, to increase the interaction between the first display screen and the second display screen, sliding tracks may be entered on both the first display screen and the second display screen, that is, a preset region of the first display screen slides onto a preset region of the second display screen, for example, slides from an edge of the first display screen to an edge of the second display screen, so as to implement a cross-screen operation, increase the interaction between the screens, increase the user interest, and improve the user experience. In the embodiment of the present invention, in order to avoid that the sliding operation is mistakenly regarded as performing other operations, for example, sliding of a page, 2 fingers may be simultaneously used, and the sliding operation is simultaneously entered, that is, when 2 sliding touch points are detected, it may be determined that the sliding operation satisfies the preset information switching condition. Further, the sliding operation may be combined with other operations to perform a determination, for example, long press first and then slide, or during sliding, the fingerprint of the sliding finger is detected, and when the fingerprint is a preset fingerprint, for example, the index finger, it is determined that the sliding operation satisfies the preset information switching condition.
The preset information switching condition may be preset by a system, or may also be user-defined, and may be specifically set according to an actual situation, which is not limited in the embodiment of the present invention. The preset information switching condition may be that the sliding direction of the sliding operation is a preset direction, for example, sliding to the left, or the sliding distance of the sliding operation reaches a preset distance threshold, for example, 2cm, or whether the sliding track of the sliding operation is "circular", or the like, which may be specifically set according to the actual situation, and the present invention is not limited. The sliding operation may include a plurality of sliding parameters such as a sliding direction, a sliding distance, a sliding track, and the like, and may be specifically obtained according to the positions of a starting point and an end point of the sliding operation, for example, if the coordinate of the starting point is (0, 1), the coordinate of the end point is (0, 5), and the sliding distance of the sliding operation is 4.
When receiving a sliding operation entered on the first display screen, the sliding parameter of the sliding operation may be acquired, the sliding parameter of the sliding operation is further matched with a preset information switching condition according to the sliding parameter of the sliding operation, and when the sliding parameter of the sliding operation is matched with the preset information switching condition, it is determined whether the sliding operation meets the preset information switching condition, for example, the preset information switching condition is: when the sliding track of the sliding operation is 'circular', and the sliding track of the sliding operation is detected to be 'circular', whether the sliding operation meets the preset information switching condition or not is determined.
And step S60, when the sliding operation is determined to meet the preset switching condition, exchanging the image data displayed by the first display screen and the second display screen.
When the sliding operation is judged to meet the preset information switching condition, the information displayed on the first display screen is displayed on the second display screen, and meanwhile, the information displayed on the second display screen can also be displayed on the first display screen, for example, the content displayed on the first display screen is A, the content displayed on the second display screen is B, when the sliding operation meets the preset information switching condition, the A is displayed on the second display screen, and the B is displayed on the first display screen.
Further, in an embodiment, after step S50, the method further includes:
and when the sliding operation is determined not to meet the preset switching condition, controlling the rotation of the front data or the back data in the screen according to the sliding direction of the sliding operation.
And when the judgment is negative, namely the sliding operation does not meet the preset switching condition, determining the sliding direction of the sliding operation, and rotating the display object in the current screen according to the sliding direction so that the display object can rotate in a certain angle range along the sliding direction. For example, when the first display screen currently displays the front data, if it is detected that the first display screen receives a sliding touch signal from the left end of the screen to the right end of the screen, and the sliding operation does not satisfy the preset switching condition for switching the display objects in the first display screen and the second display screen, the display angle of the display object in the first display screen is rotated according to the direction of the sliding touch signal, that is, the direction from the left end of the screen to the right end of the screen. Of course, the above-mentioned rotation operation is limited because image data of a certain side of a display object including front side data or back side data, etc. is displayed on both the first display screen and the second display screen. Therefore, only the boundary of the image data of a certain surface can be displayed. For example, the display object is a portrait, the first display screen displays front data of portrait data, before a sliding operation is received, the middle surface of the portrait data is displayed by default, after the portrait data is rotated according to the direction of the sliding operation, a side surface with an included angle of 30 degrees with the middle tangent plane is displayed, but the back surface of the portrait data cannot be seen, and the terminal can only be turned over when the back surface is wanted to be seen, or the sliding operation is performed according to a preset switching operation.
In another embodiment, when the holding angle of the terminal is changed, although no sliding touch operation is detected in any one of the screens, a certain rotation operation may be performed on the image data in the current screen. This process may be implemented by a gravity sensor or a gyroscope. The gravity sensor can detect the change of gravity and output related data as the name suggests. A gyroscope is also called an angular velocity sensor, and unlike an accelerometer, a measured physical quantity of the gyroscope is a rotational angular velocity in yaw and tilt. Besides the axial linear action which can be measured by the accelerometer, the gyroscope can also measure the actions of rotation and deflection, so that the complete 3D action is measured or reconstructed, and the actual action of a user can be accurately analyzed and judged. Then, according to the action, corresponding operation can be carried out on the mobile phone. For example, when a holder of the terminal rotates the terminal by a certain angle, the image data in the first display or the second display is rotated by a certain angle according to the direction of the rotation operation, and if the rotation angle of the terminal itself exceeds the limit of the rotation angle of the image data in the screen, the image data is rotated in the rotation direction up to the limit.
In the method for displaying a double-sided screen provided in this embodiment, a sliding operation entered on the first display screen or the second display screen is received; then determining whether the sliding operation meets a preset switching condition; then, when the sliding operation is determined to meet a preset switching condition, exchanging image data displayed by the first display screen and the second display screen; the method increases the interactive operation mode of the double-sided screen, improves the user experience, switches through sliding, is simple and convenient to operate, has high flexibility, and meets the requirements of users.
