Description

Technical Field

[0001] The invention relates to the field of human-computer interaction in electronic paper display devices, and in particular to a method, apparatus and electronic device for quick selection interaction in electronic paper display devices. Background Technology

[0002] With the increasing demand for eye protection, portable electronic devices using e-paper displays (such as E-ink screens), such as electronic flashcards, have become important learning tools. These devices utilize the bistable properties of e-ink to display static content, providing a paper-like reading experience, and are usually equipped with physical buttons for operation.

[0003] In existing devices of this type, when users need to choose from multiple options (e.g., selecting word meaning or mastery level during vocabulary learning), an interaction mode inherited from LCD or LED display devices is commonly used. This mode typically involves: presenting a movable cursor or highlighted focus on the display interface to indicate the current candidate option; the user moves the cursor by pressing up, down, or other arrow keys to traverse and stop at different options; and when the cursor reaches the target option, the user needs to press an additional confirmation button to complete the final selection.

[0004] However, directly applying the traditional "cursor movement-confirmation" interaction mode to e-paper display devices exposes serious technical problems that conflict with the inherent hardware characteristics of e-paper. The refresh rate of e-paper screens is significantly lower than that of conventional LCD screens. Each image update (even a partial update) requires hundreds of milliseconds of refresh time, accompanied by noticeable full-screen flicker to clear afterimages. Therefore, in the existing interaction mode, each time the user presses a directional key to move the cursor, a screen refresh is triggered to re-render the cursor position, forcing the user to go through a cycle of "pressing the key, waiting for the screen refresh to complete, observing the cursor position, and deciding whether to press the key again." This waiting process, forced by hardware refresh delay, causes noticeable lag and unresponsiveness, severely disrupting the smoothness of the interaction. Furthermore, in high-frequency, fast-paced learning scenarios (such as continuous vocabulary memorization), frequent triggering of screen refreshes solely for cursor movement exacerbates screen flicker, potentially leading to eye strain, contradicting the eye-friendly purpose of using e-paper devices, and also resulting in unnecessary power consumption increases. Summary of the Invention

[0005] Therefore, it is necessary to provide a fast selection interaction method, device, and electronic device for electronic paper display devices that can avoid frequent screen refreshes and operation delays caused by cursor movement, in order to address the above-mentioned technical problems.

[0006] This invention provides a quick selection interaction method for an electronic paper display device, the electronic paper display device including an electronic paper display unit and a physical direction button group, the method being executed by the electronic paper display device, the method comprising:

[0007] An interactive interface containing multiple candidate options is rendered and displayed simultaneously on the electronic paper display unit, wherein a movable visual focus for indicating the current candidate option is not displayed in the interactive interface;

[0008] Establish a one-to-one mapping relationship between each option in the plurality of candidate options and each specific physical direction button in the physical direction button group, wherein the mapping relationship is determined based on the spatial arrangement of each option in the interactive interface;

[0009] In response to detecting a trigger operation on a target physical direction key in the physical direction key group, the trigger operation is directly identified as a selection operation on the option mapped to the target physical direction key according to the mapping relationship, and the subsequent logic corresponding to the option is executed.

[0010] During the process of responding to the trigger operation and executing the subsequent logic, the electronic paper display unit does not perform an interface refresh triggered by moving the movable visual focus; and the interactive interface is configured as a static display interface, and the electronic paper display unit is only triggered to perform an interface refresh once when the content of the set of candidate options changes as a whole; the change in the content of the set of candidate options includes at least one of the following situations: the text content of the options to be displayed changes due to the switching of learning content; the function type of the options to be displayed changes due to the switching of learning stages.

[0011] In one embodiment, establishing a one-to-one mapping relationship between each option in the plurality of candidate options and each specific physical direction key in the physical direction key group includes:

[0012] Each of the candidate options presented in the interactive interface is uniquely mapped to a physical button with a specific directional indication in the physical direction button group.

[0013] In one embodiment, the plurality of candidate options includes at least a plurality of definition options for word meaning recognition; and the execution of the subsequent logic corresponding to the option includes: using the user's selection result of the target definition option as the confirmation basis for word learning.

[0014] In one embodiment, the arrangement of the plurality of interpretation options displayed in the interactive interface is configured such that the position of each interpretation option corresponds intuitively in space to the direction of a physical direction button.

[0015] In one embodiment, the plurality of candidate options includes at least a plurality of degree options for marking the level of learning mastery; and the execution of the subsequent logic corresponding to the option includes: updating the mastery status mark corresponding to the current learning content according to the user's selection of the target degree option.

[0016] In one embodiment, after updating the mastery status flag, the method further includes:

[0017] Control the electronic paper display unit to refresh, so as to display the next learning content and a new set of corresponding options;

[0018] A new one-to-one mapping relationship is re-established between the new set of candidate options and the physical direction button group.

[0019] In one embodiment, the plurality of candidate options in the interactive interface are divided into at least two groups, each corresponding to a directional button in a different dimension of the physical direction button group.

[0020] In one embodiment, the physical direction button group includes at least an up button, a down button, a left button, and a right button; and the interactive interface includes at least one first group of options and at least one second group of options; the first group of options is arranged vertically and mapped to the up button and the down button respectively; the second group of options is arranged horizontally and mapped to the left button and the right button respectively.

[0021] In one embodiment, the interactive interface is configured as a static display interface, and the electronic paper display unit is only triggered to perform an interface refresh when the content of the set of candidate options undergoes a complete change; the complete change of the content of the set of candidate options includes at least one of the following situations:

[0022] Switching learning content causes changes to the text content of the options that need to be displayed;

[0023] Switching between learning phases results in a change in the types of options that need to be displayed.

[0024] The present invention also provides a quick selection interaction device for an electronic paper display device, the electronic paper display device including an electronic paper display unit and a physical direction button group, the device comprising:

[0025] The rendering and display module is used to render and display an interactive interface containing multiple candidate options on the electronic paper display unit at one time, wherein the interactive interface does not display a movable visual focus for indicating the current candidate option;

[0026] The mapping relationship establishment module is used to establish a one-to-one mapping relationship between each option in the plurality of candidate options and each specific physical direction button in the physical direction button group. The mapping relationship is determined based on the spatial arrangement of each option in the interactive interface.

[0027] The mapping response module is used to respond to the detection of a trigger operation on a target physical direction key in the physical direction key group, and directly identify the trigger operation as a selection operation on the option mapped to the target physical direction key according to the mapping relationship, and execute the subsequent logic corresponding to the option.

[0028] During the process of responding to the trigger operation and executing the subsequent logic, the electronic paper display unit does not perform an interface refresh triggered by moving the movable visual focus; and the interactive interface is configured as a static display interface, and the electronic paper display unit is only triggered to perform an interface refresh once when the content of the set of candidate options changes as a whole; the change in the content of the set of candidate options includes at least one of the following situations: the text content of the options to be displayed changes due to the switching of learning content; the function type of the options to be displayed changes due to the switching of learning stages.

[0029] The present invention also provides an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement a quick selection interaction method for an electronic paper display device as described above.

[0030] The aforementioned fast selection interaction method, device, and electronic device for e-paper display devices render a static interactive interface without a movable visual focus in a single step and pre-establish a direct mapping relationship between options and physical directional buttons. This allows a single trigger operation of a specific physical directional button by the user to be directly recognized as the final selection of the corresponding option. This design fundamentally eliminates the traditional interaction process that relies on the movement of the cursor or focus between options and the subsequent screen refresh. Therefore, throughout the entire process of responding to user selections, the e-paper display unit avoids performing any interface redrawing operations caused by cursor movement, thereby completely eliminating the operational lag and visual waiting caused by the e-paper screen refresh delay, and significantly reducing the screen flicker frequency caused by frequent refreshes. While improving the interaction response speed and operational smoothness, it also reduces visual fatigue and unnecessary power consumption. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] The following is combined Figures 1-5 The present invention describes a quick selection interaction method, apparatus, and electronic device for an electronic paper display device.

[0039] like Figure 1 As shown, in one embodiment, a quick option interaction method for an electronic paper display device, the electronic paper display device including an electronic paper display unit and a physical orientation button group, the method being executed by the electronic paper display device, includes the following steps:

[0040] Step S110: Render and display an interactive interface containing multiple candidate options on the electronic paper display unit at one time. The interactive interface does not display a movable visual focus (such as a highlighted cursor) used to indicate the current candidate option.

[0041] Step S120, establish a one-to-one mapping relationship between each option in multiple candidate options and each specific physical direction key in the physical direction key group, and this mapping relationship is determined based on the spatial arrangement layout of each option in the interaction interface.

[0042] Step S130, in response to detecting a triggering operation on a target physical direction key in the physical direction key group, according to the mapping relationship, directly recognize the triggering operation as a selection operation on the option mapped by the target physical direction key, and execute the subsequent logic corresponding to this option (such as judging right or wrong or recording the mastery level).

[0043] Among them, during the process of the triggering operation being responded to and the subsequent logic being executed, the e-paper display unit does not perform the interface refresh triggered by moving the movable visual focus. In this embodiment, by pre-establishing and solidifying the direct mapping between options and keys, the intermediate steps of the traditional interaction, namely "the key moves the cursor - the screen refreshes to display the new cursor position - and then the key is pressed to confirm", are completely skipped, enabling the user to complete the selection with one key press. This directly eliminates the visual delay and waiting feeling generated during this intermediate step due to the low refresh rate of the e-paper screen, realizing a smooth operation experience of "press and respond immediately"; at the same time, since multiple local screen refreshes for moving the cursor are avoided, the number of flips of the electronic ink particles is reduced, thereby reducing the screen flicker frequency, alleviating visual fatigue, and saving refresh power consumption, which is more in line with the original intention of the eye protection and long battery life design of e-paper devices.

[0044] Establishing a one-to-one mapping relationship between each option in multiple candidate options and each specific physical direction key in the physical direction key group specifically includes: uniquely mapping each candidate option presented in the interaction interface to a physical key with a specific direction indication in the physical direction key group. A dedicated physical trigger key is clearly specified for each option on each screen, constructing a definite and unambiguous corresponding relationship, providing a clear logical basis for subsequent direct recognition and response, and ensuring the accuracy and reliability of the interaction. The multiple candidate options at least include multiple paraphrase options for word meaning recognition; and, executing the subsequent logic corresponding to this option includes: using the selection result of the user on the target paraphrase option as the confirmation basis for word learning. Refer to Figure 2 , in the interface for displaying the word "light" and its paraphrase options, this method enables the user to directly press the physical direction key corresponding to the paraphrase option considered correct (such as the option "light..." at the bottom and mapped to the down key) without moving the cursor, and the system immediately recognizes this pressing operation as the selection of this paraphrase and judges it as correct. Applied to the word meaning test scenario, it greatly improves the answering speed and reduces the interruption of the continuity of learning and memory caused by interaction lag. The arrangement layout of the multiple paraphrase options displayed in the interaction interface is configured such that the position of each paraphrase option forms an intuitive spatial correspondence with the direction of a physical direction key. For example, in Figure 2 In the vertical list shown, the top option is mapped to the up button, the middle option to the left button, and the bottom option to the down button. This leverages human intuition about spatial orientation to associate the visual position of screen options with the position of physical buttons (up, down, left, right), reducing the user's memory and cognitive burden, making operation more intuitive, and facilitating "blind operation."

[0045] The multiple candidate options include at least several level options for marking the degree of learning mastery; and the subsequent logic corresponding to that option is executed, including: updating the mastery status marker corresponding to the current learning content based on the user's selection of the target level option. (See reference...) Figure 3 In the interface displaying the word "advance" and the mastery level options at the bottom, the user directly presses the physical button (down button) corresponding to their own mastery level (e.g., "fuzzy"), and the system immediately records the word's status. Applied to learning progress management scenarios, this makes recording mastery levels an extremely quick and efficient operation, improving the efficiency of the learning process. After updating the mastery status marker, the method also includes: controlling the e-paper display unit to refresh to display the next learning content and its corresponding new set of options; and re-establishing a new one-to-one mapping between the new set of options and the physical direction button group. After completing the interaction with the current word, the device enters the next learning cycle and re-initializes the button mapping for the new interface, thereby extending the rapid single-option interaction capability to a continuous, cyclical learning process, ensuring the coherence and efficiency of the entire learning session.

[0046] Multiple options in the interactive interface are divided into at least two groups, each corresponding to a different dimension of the directional buttons in the physical directional button group. This allows the interface design to accommodate more options or more complex layouts. Grouping and mapping fully utilizes limited physical directional button resources to address different interaction scenarios, increasing the flexibility and applicability of the method. The physical directional button group includes at least an up button, down button, left button, and right button; and the interactive interface includes at least one first group of options and at least one second group of options. The first group of options is arranged vertically and mapped to the up and down buttons respectively; the second group of options is arranged horizontally and mapped to the left and right buttons respectively. This provides a specific and common mapping configuration scheme, clarifying the principle that vertical layout options use the up and down buttons, and horizontal layout options use the left and right buttons, making the mapping rules clear, consistent, and easy for system implementation and user understanding.

[0047] The interactive interface is configured as a static display, triggering a refresh of the e-paper display unit only when the content of the set of candidate options changes entirely. A change in the content of the set of candidate options includes at least one of the following: a change in the text content of the options to be displayed due to a change in the learning content; or a change in the function type of the options to be displayed due to a change in the learning stage. This clarifies that the screen only refreshes globally when necessary (such as switching words or question types), remaining static throughout all option selection operations within a single interface. This further minimizes the number of refreshes on the e-paper screen, representing a broader application of the aforementioned "skip cursor movement refresh" principle, maximizing the advantages of low power consumption and flicker-free static content display on e-paper.

[0048] The method updates the mastery status marker corresponding to the current learning content, including associating the mastery status data corresponding to the target level option selected by the user with the unique identifier of the currently displayed learning content and storing it in the device's non-volatile memory. The user selection results generated by rapid interaction are persistently saved to ensure that learning progress data is not lost after the device is powered off or restarted, providing reliable data support for building a long-term, continuous, and traceable personal learning profile. Before controlling the electronic paper display unit to refresh and display the next learning content, the method further includes: dynamically determining the next learning content from the set of content to be learned based on the historical mastery status data stored in the non-volatile memory; wherein, dynamic determination includes prioritizing the selection of learning content associated with markers representing lower mastery levels in the historical mastery status data. The persistently stored historical data drives the intelligent scheduling of learning content. The system no longer presents content in a fixed order, but prioritizes pushing content with lower mastery levels and greater need for review based on the user's past mastery of each content. This changes the learning path from "sequential playback" to "on-demand push," achieving adaptive learning and significantly improving review efficiency and consolidation effects within a limited learning time. The system dynamically determines the next learning content based on historical mastery data. Specifically, when it detects that for the same learning content, the associated stored mastery data has been marked as the highest mastery level in multiple consecutive learning sessions, the learning content is removed from the current cycle of the learning content set, and the overall progress information of the learning content set is updated. Subsequently, priority selection logic is executed from the updated learning content set to determine the next learning content. This achieves automated and dynamic management of the learning content set. The system can automatically identify and filter out content that has already been mastered, ensuring that the current learning cycle always focuses on the knowledge points to be mastered, avoiding wasting screen refresh resources and user time on already mastered content. At the same time, synchronously updating the overall progress information ensures the consistency between the user interface (such as the progress bar) display and the actual internal learning progress, maintaining the accuracy of user expectations. This forms a complete learning-evaluation-optimization closed loop, allowing the learning process to continuously refine itself as the user's ability improves.
