As an alternative, the audio output port is not provided on the dual-screen device housing, and the dual-screen device is connected to the Bluetooth speaker 1612 via Bluetooth, thereby making the dual-screen device thinner and lighter.

The hardware architecture and the software described above form a functional architecture of the dual-screen device of the embodiment of the present invention. For example, the display device 12, the button 141, and the USB 152 are respectively combined with respective drivers to implement corresponding functions. As shown in FIG. 3, functionally speaking, the dual screen device according to an embodiment of the present invention includes a display output module and a flash card learning and self-test module 21. The display output module is configured to output an image to be displayed to the two screens on the front and back sides of the dual screen device, including the display device 12 and the display driver. The flash card learning and self-test module 21 is configured to output a flash card sequence to the display output module, and control the display output module to display the front side of the flash card on the front screen and the reverse side of the flash card on the reverse screen. Further, the flash card learning and self-test module 21 includes a flash card sequence output sub-module 211 and an update display control sub-module 212, as shown in FIG.

The flash card sequence output sub-module 211 is configured to send the original flash card content forming flash card sequence from the database to the update display control sub-module 212. An example of a flash card output sequence is that different flash cards are arranged in alphabetical order or in random order in the front content. Different flash cards are output once and then output again, and thus cycle. Another example of an output sequence is that the repetition frequency and repetition interval of each card can be generated according to a human memory rule, called spatial repetition. Smart draw is a learning method. The dual-screen device sets a time node for the next display based on the historical record of the user's self-test for each flash card based on the Ebbinghaus memory curve for different flash cards. Specifically, based on the time point when the user last knows the correct answer of a flash card and the total length of time that the user views the problem face of the flash card, the time node dual screen displayed by the different flash cards is determined. In this way, the device intelligently extracts the next flash card displayed on the dual-screen device, and the user can use it to self-detect and simultaneously remember. The flash card that has been basically mastered is displayed at a lower frequency than the flash card that has not yet been mastered. The intelligent ticking algorithm can be a simple Leithner system algorithm or other algorithms.

The update display control sub-module 212 is configured to generate a front display image and a reverse display image one by one for each flash card content in the flash card sequence, and control the display output module to update the screen facing the user according to the update instruction input by the user. The content displayed. In one embodiment, the update command entered by the user is entered via button 141. In another embodiment, the update command entered by the user is entered via the motion detection module. The motion detection module includes a motion detection device 142, an input control interface 143, and a driver. For the user to input an update command via the motion detection module, the motion detection module is configured to detect which form of motion, such as rotational motion or linear motion, the motion of the dual screen device. The motion detection module can determine whether the detected motion is a prescribed motion or a random motion, and if it is a prescribed motion, the identification is which of the prescribed motions. An example of a specific display update process is shown in FIG. Step S1, the motion detection module detects the user input instruction; in step S2, the motion detection module detects whether the motion of the dual screen device is the first rotation mode, and if it is the first rotation mode, performs step S3, otherwise returns to step S1; step S3, updates The display control sub-module 212 receives the notification that the motion detection module detects that the user rotates the dual-screen device in the first rotation mode, and controls the display output module to determine whether the front screen and the reverse screen are displaying the front and back of the same flash card, if two screens If the same flash card is displayed, proceeding to step S4, otherwise proceeding to step S5; step S4, displaying the front screen update as the front side of the next flash card, returning to step S1; and step S5, displaying the reverse screen update as lower On the reverse side of a flash card, return to step S1. The first rotation mode is, for example, a manner in which the dual screen device is turned in the longitudinal direction.

On the one hand, if at least one of the two screens of the dual-screen device is an electronic paper screen, due to the material characteristics of the electronic paper screen, there will be a delay of one or two seconds when the screen is updated, so the reverse facing of the dual-screen device is updated. The scheme of the user's content on one screen solves the delay problem that the user needs to wait when changing the content of the electronic paper screen. On the other hand, the action of flipping the dual-screen device is consistent with the user's reading of the paper flash card, and conforms to the user's traditional reading habits, which makes the user more comfortable and smoother to use.

If there is a function of optimizing self-detection according to the user history learning situation, the flash card learning and self-test module 21 further includes a flash card memory condition feedback sub-module 213, as shown in FIG. The flash card memory condition feedback sub-module 213 is configured to obtain the latest memory status of the flash card by the user and instantly update the user's history record of each flash card memory. The flash card memory condition feedback sub-module 213 records the user's memory of the knowledge points on the flash card according to the direction in which the user rotates the dual-screen device. As an alternative to input via the motion detection module, the dual screen device may also provide a button 141 for the user to enter memory condition information. Therefore, the flash memory condition feedback sub-module 213 has a function of matching the motion detected by the motion detection module or the different button presses to the input memory condition information.

The working principle is that when the user sees that the problem on the front side of the dual-screen device is easily associated with the corresponding answer on the reverse side, the user can rotate the dual-screen device in a clockwise direction as seen from the right hand side as shown in FIG. 6A. Conversely, if the user sees a positive problem but cannot associate the opposite answer, the user rotates the dual screen device in a counterclockwise direction as viewed from the right hand side as shown, for example, in FIG. 6B. The dual-screen device obtains the user's information on the memory of the knowledge point by recognizing the direction of rotation of the dual-screen device, and updates the flash card memory history record 1312 in the memory 13. Further, after the user sees the content on the reverse side, if it is the same as previously known, the dual-screen device is rotated in a clockwise direction as viewed from the right hand side as shown in FIG. 6A, for example, as shown in FIG. 6B. Rotate the dual-screen device in the counterclockwise direction as seen from the right hand side. Users can assign the meaning of the two directions of rotation according to their own usage habits.

An example of a specific process for obtaining a flash card memory situation will be described below. This is shown in Figures 7A and 7B. An example of the interface of the flash card learning and self-test module 21 is shown in Figs. 7A and 7B. The English word "Pulchritude" (beautiful; Peugeot) is displayed in the middle of the front screen shown in Figure 7A. The upper and lower parts of the screen are user instructions: If the user thinks the word is "very simple", it is indicated by the arrow "very simple". Rotate the dual-screen device in the direction. If the user thinks the word is "a bit difficult", turn the dual-screen device in the direction indicated by the arrow in front of "a bit difficult". In the middle of the reverse screen shown in FIG. 7B, the word "Pulchritude" and its English explanation "Physical beauty" are displayed. The upper and lower parts of the screen are user operation instructions: if the user sees the opposite answer, the meaning of the word that is thought of before the user answers the answer, Then turn the dual-screen device in the direction indicated by the arrow in front of "Completely remember!". If the user sees the opposite answer and the meaning of the word that he thought before he flipped the answer, follow the "it seems more back" The front arrow indicates the direction of the dual screen device.

Preferably, the flash card memory condition feedback sub-module 213 also records the time point at which the user turns the dual screen device and/or records how long the user views the front screen display content.

If the dual screen device of the embodiment of the present invention has more than one usage mode, the mode selection module 25 needs to be set. The mode selection module 25 is configured to allow the user to select which usage mode the dual screen device is in, and to activate the corresponding module upon detecting which usage mode the user has selected and an instruction to initiate the selected usage mode. In the case where the mode selection module 25 is provided, the purpose of menu selection is also achieved by the motion detection module. Preferably, the instruction to initiate the selected usage mode may specifically be an action of detecting that the user flips the dual screen device. With the cooperation of the motion detection module and the screen display, the dual screen device does not need to set multiple buttons. The flash card learning and self-test module 21 is coupled to the mode selection module 25 and is further configured to initiate operation in accordance with a start command of the mode selection module 25.

In a preferred embodiment, the dual screen device may also include a knowledge point test module 22. The knowledge point test module 22 is configured to initiate a run according to a start command of the mode selection module 25, and is further configured to control the display output module to display a test knowledge point on the front screen, and at least in the upper left, upper right, lower left, and lower right portions of the reverse screen. The two sections display at least two answer options for the question.

Preferably, the knowledge point testing module 23 is connected to the motion detecting module, and is located when receiving the notification that the motion detecting module detects which part of the upper left, upper right, lower left and lower right portions of the dual screen device is tilted downward and then quickly lifts up. Select and confirm the options in the corresponding section.

The working principle is to run the knowledge point test module 22. After the user sees the content on the front side, the dual screen device is rotated to see the other side of the option. The options are up to four items, occupying the top left, top right, bottom left, and bottom right portions of the screen. The user tilts the side of the option that he wants to select, and the option is selected on the screen. After the user confirms, the user selects it quickly and then selects it. In order to improve the accuracy of the selection, you can also use a button instead of a fast upward lift to make the final selection behavior. The user confirms by flipping the dual screen device. The user can change the selection by re-tilting and then quickly lifting it before flipping the dual-screen device.

An example of the interface of the knowledge point test module 22 is shown in Figures 8A and 8B. The front screen shown in FIG. 8A displays the English word "cat", and the reverse screen shown in FIG. 8B displays the corresponding Chinese meaning options: "cat", "dog", "car", and "cow", occupying the screen. Four parts of the upper left, upper right, lower left, and lower right. The user tilts the side of the option that he wants to select, and the option is selected on the screen. After the user confirms, the user selects it quickly and then selects it.

The knowledge point test module 22 can also be configured to count the user's memory response to the flash card according to the test result, such as the user's answer to the error, such as the example shown in FIG. 8A and FIG. 8B, if the user chooses to confirm the "cat" corresponding The Chinese meaning is that the option "cat" is correct. If the user chooses to confirm any of the other three options, the answer is incorrect, and the statistical result is stored in the flash memory history record 1312 in FIG. 3, so that In addition to the statistical information input by the user in the card learning and self-test module 21, the dual-screen device can obtain more objective flash card memory information.

The dual screen device may also include a game module 23. The game module 23 is configured to initiate a run in accordance with a launch command of the mode selection module 25, and is further configured to enable the user to practice the knowledge points based on the mini-game of the flash card content. The game module 23 includes, for example, a game of guessing the opposite side, and using the dual screen feature of the dual screen device, the game of guessing the opposite side can practice the knowledge point. The specific rules of the game are: two players sit face to face on both sides of the dual screen device, the dual screen device can stand on the desktop, or can be held by one of them, each person can only see one screen of the dual screen device, ie The front or back of the flash card. The smartphone or ipad is connected to the dual-screen device via Bluetooth, and the user presses the start button on the mobile phone to display a flash card content on the dual-screen device. The two players need to quickly guess the opposite side of the side of the flash card that they can see. The player who guessed first wins a little. The player can select the right person by the touch screen on the mobile phone, so that the mobile phone automatically records the result of the game, and controls the dual-screen device to display the next flash card. And so on, the people who won the most points win. It can be seen that the game module 23 controls the dual-screen device to play games by using a communication connection between a smart device such as a computer, a mobile phone or an ipad and a dual-screen device. At this time, the game module 24 is located in the smart device 3 such as a computer, a mobile phone, or an ipad. The player's memory of the flash card that the player knows in the game can be transferred to the flash card memory history record 1312 in Figure 4 via Wifi or Bluetooth, so that the dual-screen device can obtain a more objective flash card. Memory information.

Preferably, the dual screen device may further include a reading module 24 configured to start the operation according to the startup command of the mode selection module 25, and further configured to control the display output module to display the adjacent two pages of the book on the front screen and the reverse screen, respectively. .

The reading module 24 is further configured to update the content of the screen display that is facing away from the user based on the detected update instructions entered by the user. The update command input by the user can be input via the button 141 and can also be input via the motion detection module. An example of updating the display according to the update instruction input via the motion detection module is: controlling the display output module to display the screen of the nth page content upon receiving the notification that the motion detection module detects that the user rotates the dual screen device in the second direction And the screen displaying the nth page content in the screen displaying the n+1th page content is updated to display the n+2th page content. The reading module 24 controls the display output module to display the screen of the n+2th page content and display the n+1th page content upon receiving the notification that the motion detecting module detects that the user rotates the dual screen device in a direction opposite to the second direction. The screen that displays the n+2th page of the screen is updated to display the nth page of content. The second rotation mode is, for example, a manner in which the dual screen device is turned in the lateral direction.

Obviously, as an alternative, the page turning function can be implemented by the button 141 and the motion detecting module.

An example of the interface of the mode selection module 25 in the dual screen device according to an embodiment of the present invention is shown in FIGS. 9A to 9C. First, as shown in FIG. 9A, the "product logo, or picture" is displayed on the front screen of the dual-screen device, and the user operation instruction "Flip me to start the selection mode" is displayed below, and the user enters the reverse selection menu by flipping the dual-screen device. As shown in Figure 9B, the reverse screen shows four usage modes: "card learning and self-testing", "knowledge point testing", "game", and "reading". The user can select options by means of buttons or tilting the dual-screen device, and select which mode is used in which of the four usage modes is tilted, and then the screen highlights the selected option, such as As shown in Figure 9C, the prompt "Flip me to start" appears on the selected option. Finally, enter the selected usage mode by flipping the screen. The reason for determining the instruction by flipping the dual-screen device is that the dual-screen device screen is an electronic bank card size, and the touch screen and the button input method are relatively complicated in operation, and the method of inputting the user instruction by flipping the dual-screen device is simple, and the operation can be simple. Hand operation.

An example of the operation process of the dual screen device of the embodiment of the present invention is shown in FIG. In step S21, the dual-screen device switch is pressed to turn on the motion detecting device. In step S22, the screen displays the mode selection state, the front side of the screen is as shown in FIG. 9A, and the reverse side of the screen is shown in FIG. 9B. In step S23, one of the modes is selected on the reverse side of the dual-screen device. For example, as shown in FIG. 9C, after the dual-screen device is flipped, the module corresponding to the selected mode is turned on. In step S24, the module corresponding to the selected mode is run. In step S25, it is detected whether the dual-screen device is flipped. If it is reversed, the process proceeds to step S26, otherwise, the process returns to step S24.
