ELECTRONIC APPARATUS AND METHOD FOR PROCESSING INPUT FROM STYLUS PEN IN ELECTRONIC APPARATUS

BACKGROUND
Field

The disclosure relates to an electronic apparatus and a method for processing an input from a stylus pen in an electronic apparatus.

Description of Related Art

An electronic apparatus is being developed to be able to receive various inputs from a user via a specified input device (e.g., a stylus pen) connected to the electronic apparatus through wireless communication. The electronic apparatus may identify a position on the electronic apparatus designated by an input device having a pen function (which may be referred to as a “stylus pen” hereinafter for convenience of description), and may perform a corresponding function.

The stylus pen may include wireless communication, and may provide various functions, such as pressure information about the stylus pen, battery state information, or event information according to a button input, through a display of the electronic apparatus linked with the stylus pen.

When an application including an input area for displaying a text input through a keypad is executed, the electronic apparatus may separately provide a handwriting area for displaying handwriting data via the stylus pen through the application.

In addition, when the application including the input area for displaying text input through the keypad is executed, the electronic apparatus may provide a copy and paste function as data stored in a clipboard is displayed by selection of a menu present on the keypad.

When an application including an input area for displaying a text input through a keypad is executed, an electronic apparatus may provide a handwriting area for displaying handwriting data via the stylus pen by additional selection of a user. When handwriting data is input in the handwriting area, the electronic apparatus converts the input handwriting data into text data and displays the text data in the input area, making it difficult to intuitively recognize the text data.

Further, the electronic apparatus is able to provide data stored in a clipboard only in the electronic device, and is not able to share the data stored in the clipboard with an external electronic apparatus.

SUMMARY

According to various example embodiments, an electronic apparatus may include: a display and a processor, wherein the processor may be configured to: convert handwriting data being input into text data based on input of the handwriting data with a stylus pen being detected in a second input area including a first input area in a first state of waiting for an input of handwriting data and switch to a second state in which the converted text data is displayed as preview data in the first input area while displaying the handwriting data being input in the second input area, and determine the text data displayed as the preview data as input data and switch to a third state in which the converted text data is displayed in the first input area based on termination of the input of the handwriting data being detected.

According to various example embodiments, a method for processing an input from a stylus pen in an electronic apparatus may include: converting handwriting data being input into text data based on input of the handwriting data with a stylus pen being detected in a second input area including a first input area in a first state of waiting for input of handwriting data, switching to a second state in which the converted text data is displayed as preview data in the first input area while displaying the handwriting data being input in the second input area, and determining the text data displayed as the preview data as input data and switching to a third state in which the converted text data is displayed in the first input area based on termination of the input of the handwriting data being detected.

According to various example embodiments, handwriting data corresponding to an input from a stylus pen may be displayed in an extended input area including an input area, and the handwriting data may be converted to be displayed as text data in the extended input area when the input from the stylus pen is terminated, thereby providing convenience for a user. Further, while displaying the handwriting data by the input from the stylus pen in the extended input area, the handwriting data may be converted into text data to be displayed as preview data, thereby preventing and/or reducing incorrect input of the handwriting data.

According to various example embodiments, an electronic apparatus may share data stored in a clipboard with an external electronic apparatus, thereby providing convenience of being able to continuously use the data.

FIG. 3 is a block diagram 300 illustrating an example configuration of a stylus pen (e.g., the stylus pen 201 of FIG. 2) according to various embodiments.

Referring to FIG. 3, according to various embodiments, the stylus pen 201 may include a processor (e.g., including processing circuitry) 220, a memory 230, a resonant circuit 287, a charging circuit 288, a battery 289, a communication circuit 290, an antenna 297, a trigger circuit 298, and/or a sensor 299. In various embodiments, the processor 220, at least part of the resonant circuit 287, and/or at least part of the communication circuit 290 of the stylus pen 201 may be configured on a printed circuit board or in the form of a chip.

According to various embodiments, the resonant circuit 287 may resonate based on an electromagnetic signal generated from a digitizer (e.g., the display module 160) of the electronic apparatus 101, and may radiate an electromagnetic resonance (EMR) input signal (or magnetic field and) by resonance. The electronic apparatus 101 may identify a position of the stylus pen 201 on the electronic apparatus 101 using the EMR input signal. For example, the electronic apparatus 101 may identify the position of the stylus pen 201, based on a magnitude of an induced electromotive force (e.g., an output current) generated by the EMR input signal, in each of a plurality of channels (e.g., a plurality of loop coils) in the digitizer. Although the electronic apparatus 101 and the stylus pen 201 have been described above as operating based on an EMR method, which is merely for illustration, the electronic apparatus 101 may generate a signal based on an electric field, based, for example, and without limitation, on an electrically coupled resonance (ECR) method. The resonant circuit of the stylus pen 201 may resonate by an electric field. The electronic apparatus 101 may identify a potential in a plurality of channels (e.g., electrodes) by resonance in the stylus pen 201, and may also identify the position of the stylus pen 201, based on the potential. The stylus pen 201 may also be configured by an active electrostatic (AES) method, and those skilled in the art will understand that a type in which the stylus pen 201 is configured is not limited. The electronic apparatus 101 may also detect the stylus pen 201, based on a change in capacitance (self capacitance or mutual capacitance) associated with at least one electrode of a touch panel. In this case, the stylus pen 201 may not include a resonant circuit. In the disclosure, “panel” or “sensing panel” may be used as a term encompassing a digitizer and a touch screen panel (TSP).

According to various embodiments, the memory 230 may store information related to an operation of the stylus pen 201. For example, the information may include information for communication with the electronic apparatus 101 and frequency information related to an input operation of the stylus pen 201. In addition, the memory 230 may store a program (or an application, an algorithm, or a processing loop) for calculating information about the position of the stylus pen 201 (e.g., coordinate information and/or displacement information) from sensing data of the sensor 299. The memory 230 may store a communication stack of the communication circuit 290. The communication circuit 290 and/or the processor 220 may include a dedicated memory depending on a configuration.

According to various embodiments, the resonant circuit 287 may include a coil (or inductor) and/or a capacitor. The resonant circuit 287 may resonate based on an input electric field and/or magnetic field (e.g., an electric field and/or magnetic field generated from the digitizer of the electronic apparatus 101). When the stylus pen 201 transmits a signal using the EMR method, the stylus pen 201 may generate a signal including a resonant frequency, based on an electromagnetic field generated from an inductive panel of the electronic apparatus 101. When the stylus pen 201 transmits a signal using the AES method, the stylus pen 201 may generate a signal using capacitive coupling with the electronic apparatus 101. When the stylus pen 201 transmits a signal using the ECR method, the stylus pen 201 may generate a signal including a resonant frequency, based on an electric field generated from a capacitive device of the electronic apparatus. According to an embodiment, the resonant circuit 287 may be used to change a strength or frequency of an electromagnetic field according to a manipulation state of a user. For example, the resonant circuit 287 may provide various frequencies for recognizing a hovering input, a drawing input, a button input, or an erasing input. For example, the resonant circuit 287 may provide various frequencies for recognizing a hovering input, a drawing input, a button input, or an erasing input. For example, the resonant circuit 287 may provide various resonant frequencies according to a connection combination of a plurality of capacitors, or may provide various resonant frequencies, based on a variable inductor and/or a variable capacitor.

According to various embodiments, when connected to the resonant circuit 287, based on a switching circuit, the charging circuit 288 may rectify a resonant signal generated by the resonant circuit 287 into a DC signal, and may provide the DC signal to the battery 289. According to an embodiment, the stylus pen 201 may determine whether the stylus pen 201 is inserted into the electronic apparatus 101 using a voltage level of a DC signal detected by the charging circuit 288. Alternatively, the stylus pen 201 may determine whether the stylus pen 201 is inserted by identifying a pattern corresponding to a signal identified by the charging circuit 288.

According to various embodiments, the battery 289 may be configured to store power required for an operation of the stylus pen 201. The battery 289 may include, for example, a lithium-ion battery or a capacitor, and may be rechargeable or replaceable. According to an embodiment, the battery 289 may be charged using power (e.g., a DC signal (DC power)) provided from the charging circuit 288.

According to various embodiments, the communication circuit 290 may be configured to perform a wireless communication function between the stylus pen 201 and the communication module 190 of the electronic apparatus 101. According to an embodiment, the communication circuit 290 may transmit state information, input information, and position-related information about the stylus pen 201 to the electronic apparatus 101 using a short-distance communication method. For example, the communication circuit 290 may transmit direction information (e.g., motion sensor data) about the stylus pen 201 obtained via the trigger circuit 298, voice information input via a microphone, or information about a remaining level of the battery 289 to the electronic apparatus 101. For example, the communication circuit 290 may transmit sensing data obtained from the sensor 299 and/or information related to the position of the stylus pen 201 identified based on the sensing data to the electronic apparatus 101. For example, the communication circuit 290 may transmit information about a state of a button (e.g., a button 337) included in the stylus pen 201 to the electronic apparatus 101.

According to various embodiments, when receiving a first event from a stylus pen 201 (e.g., the stylus pen 201 of FIG. 2 and FIG. 3), the processor 420 may switch to a first state of waiting for input of handwriting data via the stylus pen 201.

According to an embodiment, when executing a first application including a first input area and detecting detachment of the stylus pen 201 inserted into the electronic apparatus 401, the processor 420 may configure a second input area for switching to the first state of waiting for the input of the handwriting data. The processor 420 may configure an input area obtained by extending the first input area by a certain area (e.g., a certain pixel) as the second input area.

According to an embodiment, when receiving the first event indicating a hovering input or a touch input from the stylus pen 201 in the second input area, the processor 420 may switch to the first state in which the second input area for inputting handwriting data with the stylus pen 201 is displayed. In the first state, the second input area may be selectively displayed. For example, the first application including the first input area may include a gallery application, a search application, a message application, and/or an Internet application. For example, the first input area may include an edit field area, a text input field area, a tool bar, and/or an input field area in HTML of the Internet.

According to various embodiments, when receiving a second event indicating input of handwriting data with the stylus pen 201 (e.g., the stylus pen 201 of FIG. 2 and FIG. 3) in the second input area in the first state, the processor 420 may switch to a second state in which the handwriting data and preview data obtained by converting the handwriting data into text data are displayed.

According to an embodiment, when detecting the input of the handwriting data with the stylus pen 201 in the second input area, the processor 420 may convert the handwriting data being input into the text data, and may switch to the second state in which the converted text data is displayed as the preview data in the first input area while displaying the handwriting data being input in the second input area.

According to an embodiment, in the second state, the processor 420 may determine the type of a letter included in the handwriting data, based on trajectory information about a touch event received from the stylus pen 201, and may display the handwriting data in the second input area.

According to an embodiment, in the second state, when detecting the input of the handwriting data with the stylus pen 201 in the second input area, the processor 420 may convert the handwriting data being input in letters into the text data, and may display the converted text data as the preview data in the first input area.

According to an embodiment, the text data displayed as the preview data in the second state is provided as a preview for the user in order to prevent and/or reduce erroneous input of the handwriting data input from the stylus pen 201, and may refer to text data before being confirmed as input data.

According to an embodiment, in the second state, the processor 420 may detect the input of the handwriting data through the stylus pen 201 in all areas of the display 460 in which an input from the stylus pen 201 is detectable including the second input area.

According to an embodiment, when the handwriting data is out of the second input area while detecting the input of the handwriting data with the stylus pen 201 in the second input area in the second state, the processor 420 may recognize the handwriting data which is out of the second input area as handwriting data in the second input area.

According to an embodiment, in the second state, the processor 420 may provide a toolbar including functions available via the stylus pen 201 at a position adjacent to the second input area. When detecting a drag gesture through the stylus pen 201, the processor 420 may move the position of the toolbar to correspond to the drag gesture. When the toolbar disappears and is then regenerated and displayed, the processor 420 may display the toolbar at a position configured as an initial position or the position where the toolbar is displayed before disappearing. The toolbar displayed at the adjacent position not overlapping the second input area may basically include, for example, a space function, a backspace function, and/or a keypad switch function, and the processor 420 may add a required function according to the first input area included in the first application. For example, a first input area indicating an email field included in an email application may include an input key for inputting text indicating an email domain address, for example “.com”, as an additional function. For example, when there is no input data in a first input area indicating a URL field included in an Internet application, an input key for inputting “www.” may be included as an additional function. For example, when there is input data in the first input area indicating the URL field included in the Internet application, an input key for inputting text indicating an Internet top-level domain, for example, “.com”, may be included as an additional function. For example, a first input area indicating a text input field included in a message application may include an input key for inputting or adding an object other than text, for example, an input key for inputting an emoticon, as an additional function.

According to an embodiment, in the second state, the processor 420 may identify recommended text data, based on the handwriting data being input through the stylus pen 201 in the second input area, and may display the recommended text data at a position adjacent to the handwriting data displayed in the second input area. The processor 420 may determine a letter to be input next, based on the handwriting data being input in the second input area, and may display the determined letter as recommended text data. The processor 420 may determine the letter to be input next, based on at least one of a probability value of a letter already input in the handwriting data, a context already input in the handwriting data, or a situation in which the handwriting data is input (e.g., the type of the first application being executed or the type of the first input area (e.g., a number field or an HTML field)), and may display the determined letter as recommended text data.

According to an embodiment, when receiving an event corresponding to a different function (e.g., a scroll function or a screen zoom function) from the input of the handwriting data from the stylus pen 201 in the first state or the second state, the processor 420 may terminate the first state or the second state, and may control the different function to be performed.

According to various embodiments, when receiving a third event from the stylus pen 201 (e.g., the stylus pen 201 of FIG. 2 and FIG. 3) or a different object in the second state, the processor 420 may switch to a third state in which the input of the handwriting data through the stylus pen 201 is terminated.

According to an embodiment, when receiving a third event of receiving no input signal from the stylus pen 201 for a certain time, receiving a third event indicating a touch input from the stylus pen 201 in an area other than the second input area within a certain time after the input of the handwriting data in the second input area is canceled, or receiving a third event indicating a touch input from a first object (e.g., a hand) in the second input area in the second state, the processor 420 may detect termination of the input of the handwriting data, and may switch to the third state.

According to an embodiment, when detecting the termination of the input of the handwriting data in the second state and switching to the third state, the processor 420 may determine, as input data, the text data displayed as the preview data in the second state, and may display the text data in the first input area.

According to an embodiment, when displaying, as the input data, the text data displayed as the preview data in the first input area in the third state, the processor 420 may delete the handwriting data displayed in the second input area.

According to an embodiment, when displaying, as the input data, the text data displayed as the preview data in the first input area in the third state, the processor 420 may cancel the display of the second input area.

According to an embodiment, when detecting a selection gesture for the recommended text data using the stylus pen 201 while displaying the recommended text data, based on the handwriting data being input through the stylus pen 201 in the second input area in the second state, the processor 420 may determine the recommended data as input data, may switch to the third state, and may display the recommended data as the input data in the first input area.

According to an embodiment, when detecting an editing gesture for the text data displayed in the first input area using the stylus pen 201 in the third state, the processor 420 may perform an editing function for the text data, based on the type of the detected editing gesture.

For example, when detecting a correction gesture using the stylus pen 201 which is superimposing a new second letter as handwriting data on a first letter among letters included in the text data displayed in the first input area, the processor 420 may convert the second letter input as the handwriting data into text data, may delete the first letter, and may display the second letter converted into the text data at the position of the deleted first letter.

For example, when detecting a deletion gesture using the stylus pen 201 which drawing a line a plurality of times on the first letter among the letters included in the text data displayed in the first input area, the processor 420 may delete the first letter.

For example, when detecting a space insertion gesture using the stylus pen 201 which is inputting a “V” shape, an arrow shape indicating a downward direction, or a shape of drawing a line in the downward direction between the first letter and a third letter among the letters included in the text data displayed in the first input area, the processor 420 may insert a space between the first letter and the third letter.

For example, when detecting an additional gesture using the stylus pen 201 which is inputting a “V” shape between the first letter and the third letter among the letters included in the text data displayed in the first input area and inputting the second letter as handwriting data in the “V” shape, the processor 420 may convert the second letter input as the handwriting data into text data, and may add and display the second letter converted into the text data between the first letter and the third letter.

According to an embodiment, when detecting a selection gesture of selecting some letters among the letters included in the text data displayed in the first input area by drawing a line thereon using the stylus pen 201 with a button 337 provided on the stylus pen 201 input and then canceling the touch input in the third state, the processor 420 may provide a text selection function of providing a relevant option menu (e.g., Copy, Cut, or Select All) for some selected letters.

According to various embodiments, when detecting the handwriting data input using the stylus pen 201 in the first input area as emoji data in the second state, the processor 420 may detect first emoji data corresponding to emoji data drawn by the handwriting data among a plurality of pieces of emoji data stored in the electronic apparatus 401, and may display the first emoji data in the first input area.

According to an embodiment, while displaying the first emoji data in the first input area, the processor 420 may display an input window including a plurality of pieces of emoji data, and may display emoji data selected from the input window in the first input area instead of the first emoji data, or may additionally display the selected emoji data in the first input area displaying the first emoji data.

According to various embodiments, the processor 420 may share data stored in a clipboard of the electronic apparatus 401 with a first external electronic apparatus.

According to an embodiment, the processor 420 may store a plurality of pieces of clip data in an area of the memory 430 corresponding to the clipboard.

For example, the plurality of pieces of clip data stored in the clipboard may include text data copied from the Internet, image data copied from the Internet, text data copied from a message, or image data shared from an SNS.

For example, a storage type of the first clip data may include text data, a URI, intent, HTML, or image data. The text data is a most general format, and may store long text data without any particular restriction on length. The uniform resource identifier (URI) stores a URI indicating the location of data in the clipboard, and may store only a URI to refer to the location of data, but the actual data may be received from a content provider (CP) after obtaining the URI. The intent stores data related to a command to execute an application, and may be used for a shortcut to an activity or a service.

According to an embodiment, the processor 420 may determine the first external electronic apparatus which logs in with the same user account as a user account of the electronic apparatus 401 among at least one external electronic apparatus detected based on a first communication module (e.g., a BLE communication module) included in the communication module 490, and may transmit at least one first clip data selected for sharing among the plurality of pieces of clip data stored in the clip board to the first external electronic apparatus.

When the first clip data has a data size less than or equal to a predetermined value, the processor 420 may transmit the first clip data (e.g., text data) including raw data to the first external electronic apparatus through the first communication module, based on a first transmission method (e.g., a real-time transfer method).

When the first clip data has a data size equal to or greater than the predetermined value, the processor 420 may transmit the first clip data (e.g., image data) including only metadata without the raw data to the first external electronic apparatus through the first communication module, based on a second transmission method (e.g., a delayed transfer method). Since original address information about the first clip data is included in the metadata of the first clip data, the processor 420 may change the original address information to address information in which the raw data of the first clip data is stored in the electronic apparatus 401, and may transmit the first clip data including only the changed metadata to the first external electronic apparatus.

According to an embodiment, when receiving a request for the raw data of the first clip data (e.g., the image data) from the first external electronic apparatus, the processor 420 may transmit the raw data of the first clip data to the first external electronic apparatus through a second communication module (e.g., a Wi-Fi communication module) included in the communication module 490.

It should be appreciated that various embodiments of the disclosure and the terms used therein are not intended to limit the technological features set forth herein to particular embodiments and include various changes, equivalents, or replacements for a corresponding embodiment. With regard to the description of the drawings, similar reference numerals may be used to refer to similar or related elements. It is to be understood that a singular form of a noun corresponding to an item may include one or more of the things, unless the relevant context clearly indicates otherwise. As used herein, each of such phrases as “A or B”, “at least one of A and B”, “at least one of A or B”, “A, B, or C”, “at least one of A, B, and C”, and “at least one of A, B, or C”, may include any one of, or all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, such terms as “1st” and “2nd”, or “first” and “second” may be used to simply distinguish a corresponding component from another, and does not limit the components in other aspect (e.g., importance or order). It is to be understood that if an element (e.g., a first element) is referred to, with or without the term “operatively” or “communicatively”, as “coupled with”, “coupled to”, “connected with”, or “connected to” another element (e.g., a second element), the element may be coupled with the other element directly (e.g., wiredly), wirelessly, or via a third element.

As used in connection with various embodiments of the disclosure, the term “module” may include a unit implemented in hardware, software, or firmware, or any combination thereof, and may interchangeably be used with other terms, for example, “logic”, “logic block”, “part”, or “circuitry”. A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).

Various embodiments as set forth herein may be implemented as software (e.g., the program 140) including one or more instructions that are stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., the electronic device 101).
