[0016] FIG. 1 is a block diagram illustrating an electronic apparatus according to an example.
[0017] Referring to FIG. 1 , an electronic apparatus 100 may include a capacitive touch panel 110 and a processor 120.
[0018] The capacitive touch panel 110 may include a display panel. In an example, the electronic apparatus 100 may receive an input (e.g., a command) through the capacitive touch panel 110 and display data. The capacitive touch panel 110 may recognize an input tool or coordinates by detecting an amount of change of capacitance. For example, the capacitive touch panel 110 may include a touch sensing function to detect an amount of change of capacitance based on the input tool directly touching a surface of the capacitive touch panel 110, a proximity sensing function to detect an amount of change of capacitance based on the input tool being located at a specific distance from a surface of the capacitive touch panel 110, or a hovering touch function to detect an amount of change of capacitance based on the input tool being located within a certain distance from a surface of the capacitive touch panel 110. In an example, the input tool may include a finger of the user, a stylus pen, and the like.
[0019] The processor 120 may control an operation of the electronic apparatus 100. The processor 120 may operate in various sensing modes based on the amount of change of capacitance according to a distance between the capacitive touch panel 110 and the input tool or the touch thereof. For example, the processor 120 may operate in a proximity sensing mode if the input tool is recognized in a predetermined threshold distance area from a surface of the capacitive touch panel 110. The processor 120 may operate in a hovering sensing mode if the input tool is recognized within a predetermined threshold distance from the surface of the capacitive touch panel 110. In addition, the processor 120 may operate in a touch sensing mode if the touch is recognized on the surface of the capacitive touch panel 110.
[0020] The processor 120 may activate the capacitive touch panel 110 in a power saving state based on operating in the proximity sensing mode. In an example, the processor 120 may activate the capacitive touch panel 110 in the power saving state based on the input tool being recognized for a predetermined first time or longer in a predetermined threshold distance area. In addition, the processor 120 may switch the activated capacitive touch panel 110 to the power saving mode if the input tool is not recognized for a predetermined second time or longer. Based on the capacitive touch panel 110 being in the power saving state, the processor 120 may set a scanning rate of scanning the capacitive touch panel 110 as a first value. If the capacitive touch panel 110 is activated and operates in the hovering sensing mode, the processor 120 may set the scanning rate as a second value greater than the first value. In addition, if the capacitive touch panel 110 operates in the touch sensing mode, the processor 120 may set the scanning rate as a third value greater than the second value. In an example, the electronic apparatus 100 may reduce the power consumption by switching the capacitive touch panel 110 to the power saving mode based on the input tool not being recognized. In addition, the electronic apparatus 100 may reduce the power consumption by setting the value of the scanning rate to a lower value than that in the touch sensing mode based on operating in the hovering sensing mode. [0021] The processor 120 may recognize coordinates of the input tool based on operating in the hovering sensing mode or the touch sensing mode. In an example, there may be a plurality of areas divided from the surface of the capacitive touch panel 110 according to distances and the hovering sensing mode may include separate hovering sensing modes corresponding to respective divided areas. For example, the hovering sensing mode may include a plurality of hovering sensing modes based on the distances from the surface of the capacitive touch panel 110. In an example in which the input tool is located within a certain distance, the processor 120 may operate in one hovering sensing mode corresponding to the distance of the input tool among the plurality of hovering sensing modes.
[0022] In an example, the electronic apparatus 100 may include a controller to process a signal relating to the input tool detected on the capacitive touch panel 110, a location of the detected input tool, a touch by the detected input tool, or the like. The controller to process the signal related to the input tool may be included in the capacitive touch panel 110 or included in the processor 120. In an example, the electronic apparatus 100 may include a plurality of processors 120 and the controller to process the signal related to the input tool may be included in one of the plurality of processors 120.

The capacitive touch panel 110 is to perform the same functions as the capacitive touch panel 110 of FIG. 1 and therefore an overlapped description will not be provided. The processor 120 is to perform the same functions as the processor 120 of FIG. 1 such that the description of the processor 120 made above with regard to FIG. 1 will not be repeated and content related to the constituent elements and functions added to FIG. 2 will be described below.
[0025] The sensor 130 may recognize a situation of the electronic apparatus 100, an object around the electronic apparatus 100, or the like. In an example, the sensor 130 may detect an input tool within a certain distance of the capacitive touch panel 110. The sensor 130 may include an acceleration sensor, a gravity sensor, a gyro sensor, a geomagnetic sensor, a direction sensor, a motion recognizing sensor, a proximity sensor, an infrared sensor, an ultrasonic sensor, and the like. In an example, the processor 120 may operate in the proximity sensing mode or the hovering sensing mode based on the signal detected by the sensor 130.
[0026] The communication interface 140 may communicate with an external apparatus. For example, the external apparatus may include a server, a cloud, and the like. The communication interface 140 may connect the electronic apparatus 100 to the external apparatus and may be connected via a universal serial bus (USB) port, a wireless communication (e.g., Wi-Fi 802.11a/b/g/n, near field communication (NFC), or Bluetooth) port, or the like in addition to the connection to the external apparatus via a local area network (LAN), the Internet, or the like. The communication interface 140 may be referred to as a communicator, a communication module, a communication device, or a transceiver.
[0027] The memory 150 may store at least one instruction for the electronic apparatus 100. For example, the memory 150 may store various programs (e.g., machine readable instructions) for the electronic apparatus 100 to operate according to various examples of the disclosure.
[0028] The speaker 160 may output state information of the electronic apparatus 100 as a sound. For example, if the electronic apparatus 100 is in an error state, the speaker may output a sound corresponding to the error state. The speaker 160 may output voice data converted into a voice or voice data in an audio format.
[0029] If the electronic apparatus 100 is an image forming apparatus, the electronic apparatus 100 may include the print engine 170. The print engine 170 may form an image. As an example, the print engine 170 may print a print image generated on the processor 120 on a printing medium such as paper. The print engine 170 may perform printing by an electrophotography method, an ink jet method, or the like. In addition, the print engine 170 may be a monochrome print engine capable of printing one color or may be a color print engine capable of printing multiple colors (i.e. , color printing).
[0030] Hereinabove, an example of the electronic apparatus 100 has been described. Hereinafter, various sensing modes will be described according to various examples.
[0031] FIG. 3 is a diagram illustrating various sensing modes according to an example.
[0032] Referring to FIG. 3, a diagram in which an input tool 1 is located at different distances from the capacitive touch panel is illustrated. The capacitance of the capacitive touch panel may change if the input tool 1 is located at a distance equal to or less than a certain distance from the surface of the capacitive touch panel. The amount of change of capacitance may be transferred to the processor, and the processor may operate in one sensing mode among the various sensing modes by recognizing the location of the input tool 1 based on the transferred amount of change of capacitance.
[0033] In an example, referring to FIG. 3, the capacitive touch panel may include a recognition area 11 capable of recognizing the input tool 1. The electronic apparatus may operate in the proximity sensing mode if the input tool 1 is recognized in a boundary area of the recognition area 11 . In other words, the electronic apparatus may operate in the proximity sensing mode if the input tool 1 is recognized in the predetermined threshold distance area from the surface of the capacitive touch panel. Based on the electronic apparatus operating in the proximity sensing mode, the capacitive touch panel in the power saving state may be activated. In an example, based on the input tool 1 being recognized in the predetermined threshold distance area for a certain time or longer, the electronic apparatus may activate the capacitive touch panel in the power saving state or wake up the electronic apparatus in the power saving mode. Based on the input tool 1 not being recognized for a predetermined second time or longer, the electronic apparatus may switch the activated capacitive touch panel to the power saving mode or switch the electronic apparatus to the power saving mode.
[0034] Based on the input tool 1 moving closer to the capacitive touch panel and being recognized in the recognition area 11 , the electronic apparatus may operate in the hovering sensing mode. In other words, the electronic apparatus may operate in the hovering sensing mode based on the input tool 1 being recognized within the predetermined threshold distance from the surface of the capacitive touch panel. Based on the electronic apparatus operating in the hovering sensing mode, coordinates of the input tool 1 may be recognized. Based on the input tool 1 touching the capacitive touch panel, the electronic apparatus may operate in the touch sensing mode. Based on the electronic apparatus operating in the touch sensing mode, the coordinates of the input tool 1 may be recognized.
[0035] The electronic apparatus may display a pointer corresponding to the coordinates of the input tool 1 recognized in the hovering sensing mode or the touch sensing mode. In addition, the electronic apparatus may move the displayed pointer according to the movement of the input tool 1. Further, based on the input tool 1 performing an operation of selecting a III menu displayed at the point where the pointer is located, the electronic apparatus may select the III menu displayed at the point where the pointer is located and perform a corresponding operation.
[0036] Based on the III menu being selected in the hovering sensing mode, the electronic apparatus may display a feedback for the user’s selection, such as by displaying, flashing, or the like to highlight the selected III menu. In addition, based on an operation of the input tool 1 that is maintained at a selected location for a certain time or moves in a capacitive touch panel direction being recognized while the feedback is displayed, the electronic apparatus may execute the selected III menu.
[0037] The electronic apparatus may scan the capacitive touch panel at a certain cycle to detect a location where the capacitance is changed and an amount of change. The electronic apparatus may set different scanning rates according to the sensing mode. In an example, based on the capacitive touch panel being in the power saving mode, the electronic apparatus may set the scanning rate for scanning the capacitive touch panel as a first value. Based on the capacitive touch panel operating in the hovering sensing mode, the electronic apparatus may set the scanning rate as a second value greater than the first value. Based on the capacitive touch panel operating in the touch sensing mode, the electronic apparatus may set the scanning rate as a third value greater than the second value. As the scanning rate increases, the power consumption increases. Therefore, an example in which the scanning rate is set to be lower in the power saving state and the hovering sensing mode than in the touch sensing mode may reduce the power consumption of the electronic apparatus.
[0038] In an example, the hovering sensing mode may be set as a plurality of hovering sensing modes according to distances.
[0039] FIG. 4 is a diagram illustrating a plurality of hovering sensing modes according to an example.
[0040] Referring to FIG. 4, the recognition area 11 (within a predetermined threshold distance) may include a plurality of recognition areas 11 -1 and 11 -2. The recognition area 11 may be divided into the plurality of recognition areas 11- 1 and 11 -2 according to the distances from the surface of the capacitive touch panel. A plurality of hovering sensing modes respectively corresponding to the plurality of recognition areas 11 -1 and 11 -2 may be set.
[0041] Referring to FIG. 4, based on the input tool 1 being located in the first recognition area 11 -1 , the electronic apparatus may operate in a first hovering sensing mode. Based on the input tool 1 being located in the second recognition area 11-2, the electronic apparatus may operate in a second hovering sensing mode. In other words, the hovering sensing mode may include the plurality of hovering sensing modes set to be divided based on the plurality of areas according to the distances from the surface of the capacitive touch panel. In addition, the electronic apparatus may operate in one hovering sensing mode corresponding to the distance of the recognized input tool 1 among the plurality of hovering sensing modes.
[0042] The electronic apparatus may display a user interface (III) corresponding to each hovering sensing mode or touch sensing mode.
[0043] FIGS. 5A to 5C are diagrams illustrating Ills corresponding to various sensing modes according to an example. The description will be made with reference to FIGS. 5A to 5C.
[0044] Referring to FIGS. 5A and 5B, example Ills respectively corresponding to hovering sensing modes are illustrated. The III illustrated in FIG. 5A may correspond to the first hovering sensing mode described in FIG. 4, and the III illustrated in FIG. 5B may correspond to the second hovering sensing mode. The first hovering sensing mode may be a mode corresponding to the input tool 1 being located in an area further from the surface of the capacitive touch panel, compared to the second hovering sensing mode. As the input tool 1 becomes further from the surface of the capacitive touch panel, an inaccuracy of location recognition of the input tool 1 may increase. Accordingly, a menu of the III illustrated in FIG. 5A corresponding to the first hovering sensing mode may be displayed to be larger than a menu of the III illustrated in FIG. 5B corresponding to the second hovering sensing mode. For example, the III menu may include an icon, a text, a button, and the like.
[0045] Referring to FIG. 5C, an example III corresponding to the touch sensing mode is illustrated. The touch sensing mode recognizes a touch on the surface of the capacitive touch panel, and accordingly, the location of the input tool 1 may be more accurately recognized as compared to the hovering sensing mode. Accordingly, a menu of the III illustrated in FIG. 5C corresponding to the touch sensing mode may be displayed to be smaller than the menus of the Ills illustrated in FIGS. 5A and 5B corresponding to the hovering sensing mode. As an example, a print menu 21 of FIG. 5A displayed in the first hovering sensing mode may be displayed with a largest size, a print menu 23 of FIG. 5B displayed in the second hovering sensing mode may be displayed with a medium size, and a print menu 25 of FIG. 5C displayed in the touch sensing mode may be displayed with a smallest size.
[0046] In other words, as the set distance area of the hovering sensing mode corresponding to the distance of the recognized input tool 1 becomes further from the surface of the capacitive touch panel, the electronic apparatus may increase a size of the displayed III menu. In addition, the electronic apparatus may display the III menu displayed in the touch sensing mode by reducing the size thereof to be smaller than the size of the III menu displayed in the hovering sensing mode.
[0047] In an example, the displayed III menu may include a menu to switch the mode to the hovering sensing mode or the touch sensing mode.
[0048] FIGS. 6A and 6B are flowcharts illustrating a process of setting Ills corresponding to various sensing modes according to an example. The description will be made with reference to FIGS. 6A and 6B.
[0049] Referring to FIGS. 6A and 6B, the electronic apparatus may select a control mode according to a user’s selection and execute a setting menu in operation S610. In an example, the selecting of the control mode may include selecting the sensing mode of the control mode and may include selecting the hovering sensing mode or the touch sensing mode in operation S620. Based on the hovering sensing mode being selected, the electronic apparatus may select whether to use a default setting in operation S630. Based on the default setting being selected according to the user’s selection, the electronic apparatus may apply a default layout to the III displayed in the hovering sensing mode in operation S640. In addition, based on a layout change being selected according to the user’s selection, the electronic apparatus may change the III displayed in the hovering sensing mode from the default layout to the layout selected by the user in operation S650.
[0050] Based on the touch sensing mode being selected in operation S620, the electronic apparatus may select whether to use the default setting in operation S660. Based on the default setting being selected according to the user’s selection, the electronic apparatus may apply the default layout to the III displayed in the touch sensing mode in operation S670. In addition, based on the layout change being selected according to the user’s selection, the electronic apparatus may change the III displayed in the touch sensing mode from the default layout to the layout selected by the user in operation S680. As described above, the III layout in the hovering sensing mode may have a size larger than the size of the III layout in the touch sensing mode. For example, an icon, a button, a text, and the like included in the III in the hovering sensing mode may have larger sizes than sizes of an icon, a button, a text, and the like included in the III in the touch sensing mode.
[0051] In an example, an area for recognizing proximity sensing of the input tool may be set in various areas of the capacitive touch panel.
[0052] FIGS. 7A to 7C are diagrams illustrating a proximity sensing area according to an example. The description will be made with reference to FIGS. 7A to 7C.
[0053] Referring to FIGS. 7A to 7C, a proximity sensing area in which the electronic apparatus operates in a proximity sensing mode may be set in the entire area of the capacitive touch panel (or display panel). In this case, the entire area of the capacitive touch panel may be a proximity sensing area and a touch area. In addition, referring to FIG. 7A, a proximity sensing area 31 may be disposed on an end portion (e.g., a lower end portion, an upper end portion, etc.) of the capacitive touch panel 110. In addition, an indicator 41 to indicate the proximity sensing area 31 may be disposed in the vicinity of the proximity sensing area 31. For example, the indicator 41 may include a light emitting diode (LED), a marking, a sticker, or the like. Referring to FIG. 7B, a proximity sensing area 32 may be disposed on a portion (e.g., a left portion, a right portion, etc.) of the capacitive touch panel 110. In addition, an indicator 42 to indicate the proximity sensing area 32 may be disposed in the vicinity of the proximity sensing area 32. Referring to FIG. 7C, a proximity sensing area 33 may be disposed in a partial area of the capacitive touch panel 110. In addition, an indicator 43 to indicate the proximity sensing area 33 may be disposed on a periphery of the proximity sensing area 33.
[0054] In the examples of FIGS. 7A to 7C, the proximity sensing areas are disposed in various areas of the capacitive touch panel 110. However, the proximity sensing area may be an area for recognizing the touch of the input tool, in addition to the region for recognizing the proximity of the input tool.
[0055] Hereinabove, examples of various sensing modes have been described. Hereinafter, an example method for controlling the electronic apparatus will be described.
[0056] FIG. 8 is a flowchart illustrating a method for controlling the electronic apparatus according to an example.
[0057] Referring to FIG. 8, based on the input tool being recognized in a predetermined threshold distance area, the electronic apparatus may operate in the proximity sensing mode in operation S810. For example, based on operating in the proximity sensing mode, the electronic apparatus may activate the capacitive touch panel in the power saving state or wake-up the electronic apparatus. Based on the input tool being recognized in the predetermined threshold distance area for a predetermined first time or longer, the electronic apparatus may activate the capacitive touch panel in the power saving state or wake-up the electronic apparatus. In addition, based on the input tool not being recognized for a predetermined second time or longer, the electronic apparatus may switch the activated capacitive touch panel to the power saving mode or switch the waked-up electronic apparatus to the power saving mode.
[0058] In an example, the proximity sensing area for operating in the proximity sensing mode may be set in one area of the capacitive touch panel. In addition, the indicator for indicating the proximity sensing area may be located in the vicinity of the set one area.
[0059] Based on the input tool being recognized within the predetermined threshold distance, the electronic apparatus may operate in the hovering sensing mode in operation S820. For example, the hovering sensing mode may include a plurality of hovering sensing modes set to be divided into a plurality of areas according to a distance from a surface of the capacitive touch panel. The electronic apparatus may operate in one hovering sensing mode corresponding to the distance of the recognized input tool among the plurality of hovering sensing modes. As the set distance area of the hovering sensing mode corresponding to the distance of the recognized input tool becomes further from the surface of the capacitive touch panel, the electronic apparatus may increase a size of a displayed III menu.
[0060] Based on the touch being recognized on the surface of the capacitive touch panel, the electronic apparatus may operate in the touch sensing mode in operation S830. For example, the electronic apparatus may recognize coordinates of the input tool based on operating in the hovering sensing mode or the touch sensing mode. The electronic apparatus may display a pointer corresponding to the coordinates of the input tool recognized in the hovering sensing mode and the touch sensing mode. In addition, the electronic apparatus may move the displayed pointer according to the movement of the recognized input tool. In an example, a III displayed on the electronic apparatus may include a menu for switching the mode to the hovering sensing mode or the touch sensing mode.
[0061] The electronic apparatus may differently set a scanning rate for detecting a change of capacitance according to each mode. For example, based on the capacitive touch panel being in the power saving state, the electronic apparatus may set the scanning rate for scanning the capacitive touch panel as a first value. Based on the capacitive touch panel being activated and operating in the hovering sensing mode, the electronic apparatus may set the scanning rate as a second value that is greater than the first value. Alternatively, based on the capacitive touch panel operating in the touch sensing mode, the electronic apparatus may set the scanning rate as a third value that is greater than the second value.
[0062] In an example, the electronic apparatus may inactivate the touch sensing mode and operate in the proximity sensing mode and the hovering sensing mode. In this case, in order to ensure the operation performance in the proximity sensing mode or the hovering sensing mode, the electronic apparatus may set the scanning rate as a higher value, compared to a case of using the touch sensing mode together. In an example, based on the touch sensing mode being inactivated, if the capacitive touch panel is in the power saving mode, the electronic apparatus may set the scanning rate for scanning the capacitive touch panel as a fourth value. Based on the capacitive touch panel being activated and operating in the hovering sensing mode, the electronic apparatus may set the scanning rate as a fifth value that is greater than the fourth value. The fourth value may be a value greater than the first value described above, and the fifth value may be a value greater than the second value described above.
[0063] FIG. 9 is a diagram illustrating instructions stored in a non-transitory computer readable recording medium according to an example.
[0064] The example control process performed on an electronic apparatus described above may be implemented in a form of a non-transitory computer- readable recording medium storing an instruction or data executable by a computer or a processor. A non-transitory computer-readable recording medium 900 may store instructions related to the example operations of the electronic apparatus described above. For example, the non-transitory computer-readable recording medium 900 may include instructions 910 to operate in a proximity sensing mode, instructions 920 to operate in a hovering sensing mode, and instructions 930 to operate in a touch sensing mode.
[0065] Such a non-transitory computer-readable recording medium may be a read-only memory (ROM), a random-access memory (RAM), a flash memory, CD-ROMs, CD-Rs, CD+Rs, CD-RWs, CD+RWs, DVD-ROMs, DVD-Rs, DVD+Rs, DVD-RWs, DVD+RWs, DVD-RAMs, BD-ROMs, BD-Rs, BD-R LTHs, BD-REs, a magnetic tape, a floppy disk, a magneto-optical data storage device, an optical data storage device, a hard disk drive, a solid-state drive (SSD), and any device capable of storing machine readable instructions, related data, data files, and data structures, and providing machine readable instructions, related data, data files, and data structures to a processor or a computer so that the processor or the computer may execute the instructions.
