[0039] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0040] First, the application scenarios of the embodiments of the present disclosure are introduced.
[0041] The interactive method provided in the embodiment of the present disclosure can be applied to an electronic device provided with an electromagnetic screen, wherein the electromagnetic screen can receive a resonance signal emitted by an electromagnetic pen to determine the hovering position of the electromagnetic pen on the electromagnetic screen.
[0042] For example, Figure 1 FIG. 2 is a schematic diagram showing the structure of an electromagnetic touch control system in an embodiment of the present disclosure. Figure 1 As shown, the electromagnetic touch system includes an electromagnetic pen 110 and an electromagnetic screen 120 .
[0043] The electromagnetic screen 120 may include a display layer 121 and an electromagnetic induction layer 122 .
[0044] The display layer 121 is used to display content to the user. For example, the display layer 121 may be an organic light-emitting semiconductor (OLED) panel or a liquid crystal display (LCD) panel.
[0045] For example, a touch module may be configured in the display layer 121, so that the electromagnetic screen 120 can detect touch operations of other objects (e.g., fingers, capacitive pens) in addition to the electromagnetic pen 110, so as to enrich the interaction mode of the electromagnetic screen 120. The touch module may be a capacitive touch module, a resistive touch module, or an infrared touch module, which is not limited in the embodiments of the present disclosure.
[0046] The electromagnetic induction layer 122 is disposed on the back side of the display layer 121 , ie, the side not used for displaying content.
[0047] Exemplarily, the electromagnetic induction layer 122 may include an antenna array. The antenna array may be composed of a plurality of coils staggered horizontally and vertically, and these coils can receive the resonance signal emitted by the electromagnetic pen 110. Since the coils are staggered horizontally and vertically, the horizontal coil with the strongest received resonance signal intensity and the vertical coil with the strongest received resonance signal intensity can be determined respectively, and the intersection of the horizontal coil and the vertical coil is used as the hovering position of the electromagnetic pen 110.
[0048] Exemplarily, the electromagnetic pen 110 can be an active electromagnetic pen or a passive electromagnetic pen. In the case where the electromagnetic pen 110 is a passive electromagnetic pen, the antenna array can also generate a magnetic field when powered on, so that the passive electromagnetic pen can generate an induced current, thereby enabling the passive electromagnetic pen to generate a resonant signal through the induced current.
[0049] Next, exemplary embodiments of the present disclosure will be described in detail in conjunction with the above application scenarios.
[0050] An interactive method is provided in an embodiment of the present disclosure. The method can be executed by an electronic device provided with an electromagnetic screen.
[0051] Figure 2 A flow chart of an interactive method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the interactive method provided in the embodiment of the present disclosure includes the following steps S201 to S203.
[0052] S201, the electromagnetic pen is in a hovering state, a resonance signal is received, and a hovering position of the electromagnetic pen on the electromagnetic screen is determined.
[0053] In some embodiments, the hovering state is a state in which the orthographic projection of the electromagnetic pen on the electromagnetic screen coincides with the display area of the electromagnetic screen and is not in contact with the electromagnetic screen.
[0054] Exemplarily, whether the electromagnetic pen is in contact with the electromagnetic screen can be determined based on the strength of the resonance signal received by the electromagnetic screen. Since the closer the vertical distance between the electromagnetic pen and the electromagnetic screen is, the greater the strength of the resonance signal received by the electromagnetic screen is, the resonance signal strength threshold can be set to determine that the electromagnetic pen is in contact with the electromagnetic screen when the received resonance signal is greater than the resonance signal strength threshold. The resonance signal strength threshold can be determined in advance through experiments, that is, the resonance signal strength received by the electromagnetic screen when the electromagnetic pen is in contact with the electromagnetic screen is measured in an experimental environment, and the resonance signal strength threshold is set accordingly.
[0055] Exemplarily, a touch module is provided in the electromagnetic screen. At this time, the touch module can receive a touch signal for the electromagnetic screen, thereby determining whether the electromagnetic pen is in contact with the electromagnetic screen.
[0056] For example, a pressure sensor is provided at the tip of the electromagnetic pen. At this time, the pressure on the tip of the pen can be received, and when the pressure is greater than a preset pressure threshold, it is determined that the electromagnetic pen is in contact with the electromagnetic screen. The pressure threshold can be determined in advance through experiments, that is, the pressure on the tip of the pen when the user performs a touch operation is measured in an experimental environment, and the pressure threshold is set accordingly.
[0057] The above lists a variety of ways to determine the contact between the electromagnetic pen and the electromagnetic screen. Under the concept of the embodiment of the present disclosure, other ways can also be used to determine whether the electromagnetic pen is in contact with the electromagnetic screen, and the embodiment of the present disclosure does not limit this.
[0058] Exemplarily, whether the orthographic projection of the electromagnetic pen on the electromagnetic screen coincides with the display area of the electromagnetic screen can be determined by the strength and range of the resonance signal received by the electromagnetic screen. The method of using the resonance signal to determine the posture of the electromagnetic pen is well known to those skilled in the art and will not be elaborated in this disclosure.
[0059] Based on this, the disclosed embodiment can distinguish the touch operation or other operations of the electromagnetic pen from the hovering state, thereby avoiding misjudging the touch operation or other operations of the electromagnetic pen as the hovering state.
[0060] In some embodiments, when the electromagnetic pen is in a hovering state, after receiving the resonance signal, the position where the resonance signal is received strongest can be determined as the hovering position. For the detailed principle of determining the hovering position of the electromagnetic pen, please refer to Figure 1 The description in the illustrated architecture will not be repeated here.
[0061] S202: Determine a target element in the multimedia elements displayed on the electromagnetic screen according to the hovering position.
[0062] In some embodiments, the multimedia element may be all text content currently displayed on the electromagnetic screen. In addition to text content in text form, it may also include text content in pictures or videos (which can be extracted by text recognition algorithms). This embodiment of the present disclosure is not limited to this.
[0063] In some embodiments, the target element may be the text in the multimedia element that is closest to the hovering position. In order to enable the user to accurately locate the target element through the hovering operation, when the electromagnetic pen is in the hovering state, after receiving the resonance signal, a hovering mark may be displayed on the electromagnetic screen. The position of the hovering mark corresponds to the hovering position.
[0064] Exemplarily, the hover mark may be a graphic mark such as “○” or “×”, which is not limited in the embodiments of the present disclosure.
[0065] S203, acquiring and displaying corresponding information of the target element.
[0066] In some embodiments, the corresponding information of the target element can be obtained through a network query, or through a dictionary or artificial intelligence assistant pre-configured locally in the electronic device, etc., which is not limited in the embodiments of the present disclosure. After obtaining the corresponding information of the target element, the corresponding information of the target element can be displayed.
[0067] Exemplarily, when the target element is a text element, the corresponding information of the target element may be the interpretation information of the text element. When the target element is a picture element, the corresponding information of the target element may be the description information of the picture element.
[0068] Exemplarily, the display form of the corresponding information may be a combination of one or more of text form, picture form, audio form and video form.
[0069] In some embodiments, please refer to Figure 3 , the corresponding information of the target element can be displayed in a floating window 301, and the floating window 301 covers the content displayed on the electromagnetic screen.
[0070] Please continue to refer to Figure 3 The floating window 301 can be displayed in a non-full screen style, and the floating window 301 does not cover the target element displayed on the electromagnetic screen. In other words, the display of the corresponding information will not cover the target element itself, so that the user can compare the target element and its corresponding information.
[0071] Therefore, the solution provided by the embodiment of the present disclosure can enable the user to quickly determine the target element and query its corresponding information by hovering, which has higher interaction efficiency compared with the query by touching in the related art.
[0072] In some embodiments, when the electromagnetic screen cannot receive the resonance signal, or the electromagnetic pen contacts the electromagnetic screen, it can be determined that the electromagnetic pen exits the hovering state (i.e., is in a non-hovering state), and the corresponding information of the target element can be stopped from being displayed. The former can be considered as the user lifting the electromagnetic pen, i.e., the electromagnetic pen has left the receiving range of the electromagnetic screen; the latter can be considered as the user expecting to use the electromagnetic pen to perform a touch operation, and no longer view the corresponding information of the target element.
[0073] In some embodiments, when the hovering position of the electromagnetic pen changes, the above S201 and S202 may be re-executed. That is, after stopping displaying the corresponding information of the current target element, a new target element may be determined according to the new hovering position, and the corresponding information of the new target element may be displayed.
[0074] In some embodiments, when the target element is a text element, the language type of the target element may also be detected. The language type may include a target language and a non-target language. The target language may be understood as the user's native language or commonly used language, which may be set by the user; and the non-target language may be understood as any language other than the target language.
[0075] When the language type of the target element is a non-target language, the target element of the non-target language can be converted into a target element of the target language. At this time, when acquiring and displaying the corresponding information of the target element, the target element of the target language and its corresponding corresponding information can be displayed together.
[0076] That is to say, the target elements in the non-target language can be translated through the dictionary preset locally on the electronic device or in the cloud, and the translation results and corresponding information can be displayed together.
[0077] Next, the method of determining the target element will be described in detail.
[0078] Figure 4 A schematic diagram of a target element determination method according to an embodiment of the present disclosure is shown. Figure 4 As shown, the target element determination method provided in the embodiment of the present disclosure includes the following steps S401 to S403.
[0079] S401: When the multimedia element includes a text element, perform word segmentation processing on the text element to obtain at least one candidate element.
[0080] Since the embodiment of the present disclosure finally displays the corresponding information of the target element, when the multimedia element includes a text element, the corresponding information is the analysis of a certain word in the text element, rather than the analysis of the entire sentence or paragraph. Therefore, when the multimedia element includes a text element, it is necessary to perform word segmentation processing on the text element, and decompose a large text element into a combination of several words.
[0081] In some embodiments, a word segmentation model in the field of natural language processing (NLP) may be used to perform word segmentation processing on multimedia elements to obtain at least one candidate element.
[0082] In some embodiments, the text element may also be sent to a cloud device so that the cloud device performs a word segmentation operation on the text element. The word segmentation result returned by the cloud device is then received to obtain at least one candidate element. In other words, for electronic devices with low computing power, the word segmentation process may be transferred to the cloud device for processing to increase the speed of determining the target element.
[0083] It can be understood that, for text elements, at least one candidate element is a word segmentation result, and each candidate element consists of an independent word.
[0084] S402: When the multimedia element includes a picture element, each picture in the multimedia element is taken as a candidate element.
[0085] It can be understood that, when the multimedia elements include picture elements, each picture can be regarded as an independent candidate element.
[0086] S403: Determine at least one candidate element of all candidate elements whose element positions on the electromagnetic screen are closest to the hovering position as the target element.
[0087] It should be noted that all candidate elements include both the candidate elements obtained in S401 (if the elements displayed on the electromagnetic screen include text elements) and the candidate elements obtained in S402 (if the elements displayed on the electromagnetic screen include picture elements).
[0088] In some embodiments, the distance between the element position of the candidate element on the electromagnetic screen and the hovering position can be understood as the shortest distance between the element position and the hovering position in the reference coordinate system provided by the electromagnetic screen. Here, it can be assumed that in the reference coordinate system provided by the electromagnetic screen, a line segment is used to connect the hovering position and the element position of the candidate element. When the line segment is shortest, the length of the line segment can represent the distance between the element position of the candidate element and the hovering position.
[0089] In some embodiments, when the distance between the target element position and the hovering position of the target element on the electromagnetic screen is too large, the electromagnetic pen is not suspended near the target element. At this time, the user may not want to query the corresponding information of the target element. In order to avoid the display of the corresponding information blocking the content that the user is actually viewing, the corresponding information of the target element can be displayed when the distance between the target element position and the hovering position is less than a preset distance threshold. In other words, the corresponding information of the target element can be displayed when the user determines to suspend the electromagnetic pen near the target element.
[0090] Based on the same inventive concept, the present disclosure also provides an electromagnetic screen device, such as the following embodiment. Figure 2 The method embodiment shown is similar to that shown in FIG. 1 , so the implementation of the electromagnetic screen device embodiment can refer to the above Figure 2 The implementation of the illustrated method embodiment will not be described in detail in detail.

[0092] The electromagnetic screen 501 is used to receive the resonance signal emitted by the electromagnetic pen.

[0094] In some embodiments, the control unit 502 is also used to, when the multimedia element includes a text element, perform word segmentation processing on the text element to obtain at least one candidate element; when the multimedia element includes a picture element, take each picture in the multimedia element as a candidate element; and determine at least one candidate element that is closest to the element position and the hovering position of all candidate elements on the electromagnetic screen as the target element.
[0095] In some embodiments, the control unit 502 is further configured to obtain and display corresponding information of the target element if the distance between the target element position and the hovering position on the electromagnetic screen is less than a preset distance threshold.
[0096] In some embodiments, the control unit 502 is further used to send the text element to the cloud device so that the cloud device performs a word segmentation operation on the text element; and receive the word segmentation result returned by the cloud device to obtain at least one candidate element.
[0097] In some embodiments, the control unit 502 is further configured to receive a resonance signal and display a hovering mark on the electromagnetic screen when the electromagnetic pen is in a hovering state; wherein the position of the hovering mark corresponds to the hovering position.
[0098] In some embodiments, the control unit 502 is also used to, when the target element is a text element, detect the language type of the target element, the language type including the target language and the non-target language; when the language type of the target element is a non-target language, convert the target element of the non-target language into a target element of the target language; and obtain and display the target element of the target language and its corresponding corresponding information.
[0099] In some embodiments, the control unit 502 is further configured to, when the electromagnetic pen is in a hovering state, receive a resonance signal and determine a position where the resonance signal is received most strongly as the hovering position.
