Referring to FIG. 1, an electronic device 101 according to various embodiments may include a foldable housing 110, a folding portion 120, and a display 130. The display 130 may be a flexible or foldable display disposed in a space formed by the foldable housing 110.

According to various embodiments, the foldable housing 110 may include a first housing 112 and a second housing 114. The first housing 112 may include a first surface (or a first front surface) and a third surface (or a first rear surface) which faces away from the first surface. The second housing 114 may include a second surface (or a second front surface) and a fourth surface (or a second rear surface) which faces away from the second surface.

According to various embodiments, the first housing 112 and the second housing 114 may be disposed on both sides of the folding portion 120, and connected by the folding portion 120. For example, the folding portion 120 may be coupled with a side surface of the first housing 112 and a side surface of the second housing 114 which faces the side surface of the first housing 112, and thus pivotably or rotatably interconnect the first housing 112 and the second housing 114.

According to various embodiments, the display 130 may be disposed on the first housing 112 and the second housing 114 by traversing the folding portion 120. The display 130 may be supported by the first housing 112 and the second housing 114. In various embodiments, the display 130 may be disposed on the first surface of the first housing 112 and the second surface of the second housing 114 by traversing the folding portion 120.

The electronic device 101 according to various embodiments may be folded based on the folding portion 120. For example, the folding portion 120 may be disposed between the first housing 112 and the second housing 114 of the electronic device 101, to bend, curve, or fold the electronic device 101. According to various embodiments, the first housing 112 may be connected to the second housing 114 through the folding portion 120, and may rotate based on the folding portion 120. According to various embodiments, the second housing 114 may be connected to the first housing 112 through the folding portion 120, and may rotate based on the folding portion 120. According to various embodiments, the first housing 112 and the second housing 114 may rotate based on the folding portion 120 and be folded to face each other. In various embodiments, the first housing 112 and the second housing 114 may be substantially folded or overlapped. For example, the first housing 112 and the second housing 114 rotate and fold based on the folding portion 120, wherein the first surface of the first housing 112 and the second surface of the second housing 114 face each other or the third surface of the first housing 112 and the fourth surface of the second housing 114 face each other.

According to various embodiments, the first housing 112 and the second housing 114 of the electronic device 101 may be folded out by means of the folding portion 120. According to various embodiments, if the electronic device 101 is folded out, the first surface of the first housing 112 may be substantially flush with the second surface of the second housing 114. In various embodiments, the folded out state of the electronic device 101 may indicate that a user's field of view or angle of view heading toward the front surface of the electronic device 101 covers all of a left area corresponding to the first surface of the entire area of the display 130, a right area corresponding to the second surface of the entire area of the display 130, and a center area corresponding to the folding portion 120 of the entire area of the display 130. The center area may overlap with at least part of the left area and at least part of the right area.

According to various embodiments, the first housing 112 and the second housing 114 of the electronic device 101 may be folded in by means of the folding portion 120. According to various embodiments, if the electronic device 101 is folded in, the first surface of the first housing 112 and the second surface of the second housing 114 may make an angle within a designated range. For example, if the electronic device 101 is folded in, the angle between the first surface of the first housing 112 and the second surface of the second housing 114 may be greater than 0 degree and smaller than 180 degrees.

According to various embodiments, the electronic device 101 may close the first housing 112 and the second housing 114 by means of the folding portion 120. According to various embodiments, if the electronic device 101 is closed, the first surface of the first housing 112 and the second surface of the second housing 114 may face each other and be substantially flush with each other. According to various embodiments, the closed state may indicate that the display 130 is hidden in the user's field of view which faces the front surface of the electronic device 101.

According to various embodiments, at least one sensor may be disposed in each of the first housing 112 and the second housing 114. For example, a first sensor 141 may be disposed in the first housing 112, and a second sensor 142 may be disposed in the second housing 114. According to an embodiment, the first sensor 141 and the second sensor 142 may acquire angle information between the first housing 112 and the second housing 114. The first sensor 141 may include at least one of, for example, a gyroscope sensor, a distance sensor, or a strain sensor. The second sensor 142 may include at least one of, for example, a gyroscope sensor, a distance sensor, or a strain sensor.

FIGS. 4A and 4B illustrate a program module 400 or 401 for detecting and processing a folding state in an electronic device according to various embodiments of the disclosure.

According to an embodiment, the program module 400 or 401 of FIG. 4A and FIG. 4B may be the program 240 of the electronic device 201 of FIG. 2. According to an embodiment, the program module 400 or 401 of FIGS. 4A and 4B may be at least part of the program module 300 of FIG. 3.

Referring to FIG. 4A, an event converter 420 (e.g., the folding event converter 325 of FIG. 3) may determine (or calculate) a folding state by analyzing raw data provided from a non-angle sensor 410 (e.g., the strain sensor 332, the distance sensor 333, or the gyroscope sensor 334 of FIG. 3). The folding state may indicate the angle between the first surface and the second surface of the electronic device, or the designated angle range corresponding to the angle between the first surface and the second surface of the electronic device. The folding state may indicate which one of a designated first angle range (e.g., greater than 180 degrees), a designated second angle range (e.g., greater than 0 degree and less than 180 degrees), and a designated third angle range (e.g., 0 degree) the angle between the first surface and the second surface of the electronic device corresponds to. The designated angle ranges are exemplary to facilitate the understanding, and the disclosure is not limited thereto. According to various embodiments, the designated angle ranges may be set and/or changed by the designer and/or the user. According to an embodiment, the folding state may represent increase or decrease of the folding angle. According to an embodiment, the event converter 420 may calculate a folding angle between the first surface and the second surface of the electronic device, based on data provided from a gyroscope sensor mounted on the first surface of the electronic device and data provided from a gyroscope sensor mounted on the second surface of the electronic device. The data provided from the gyroscope sensor may indicate an angle between the surface of the corresponding gyroscope sensor and a ground. According to an embodiment, based on data provided from a distance sensor mounted on the first surface of the electronic device and data provided from a distance sensor mounted on the second surface of the electronic device, the event converter 420 may calculate a distance between the first surface and the second surface of the electronic device and calculate a folding angle of the electronic device 201 based on the calculated distance. For example, since the distance between the first surface and the second surface of the electronic device is proportional to the folding angle of the first surface and the second surface of the electronic device, the folding angle corresponding to the distance may be calculated using a preset function.

A folding state manager 430 (e.g., the state manager 321 of FIG. 3) may determine whether an event occurs according to the folding state, based on folding state information provided from the event converter 420 and/or angle information provided from an angle sensor 412. The folding state manager 430 may provide the event occurrence based on the folding state to an event handler 460. The event based on the folding state may be processed by the event handler 460. The event handler 460 may be registered by various modules such as a system 440, an application 450 (e.g., the application 301 of FIG. 3), and a background service, and the registered event handler 460 may process the event based on the folding state according to a priority. For example, the priority may be determined in order of the system 440, a visible (or activated) application, an application which is being executed but is not directly visible to the user, and a background service which does not have a visible user interface. For example, if the event based on the folding state is not processed by the event handler of a high priority, the event based on the folding state may be processed by the event handler having a next priority.

According to an embodiment, the system 440 may identify the folding state of the electronic device based on an event processing request of the event handler 460, and provide the application 450 with display position information of at least one object based on the folding state. According to an embodiment, based on the event processing request of the event handler 460, the system 440 may identify a situation (e.g., a landscape mode) which satisfies a designated condition of not processing the folding event, and may not process the folding event. For example, if the electronic device 101 is in the landscape mode, the system 440 may ignore the folding event, not to change the display position of at least one object due to the folding event. According to an embodiment, the application 450 may control the display position of at least one object, based on the event processing request of the event handler 460. According to an embodiment, based on the event processing request of the event handler 460, the application 450 may control to split and display at least part of an application screen.

It has been described that, but not limited to, the folding event is not processed in the landscape by way of example. For example, according to an embodiment, the system 440 may process the folding event even in the landscape mode, depending on a design. For example, if a folding event occurs in the landscape mode of the electronic device 101, the system 440 may process the folding event to control the display position of at least one object in response to the folding event.

Referring to FIG. 4B, the folding state manager 430 forwards the event based on the folding state directly to the system 440 or the application 450, without passing through the event handler. For example, the folding state manager 430 may determine whether to forward the event based on the folding state and/or a target to which the event is forwarded, based on context information of the electronic device obtained from a context manager (the context manager 326 of FIG. 3).

According to various embodiments, a processor (e.g., the processor 220 of FIG. 2) may detect a folding state of the electronic device using at least one sensor (e.g., the sensor module 276), and control a user interface based on the folding state of the electronic device. According to an embodiment, the processor 220 may determine the folding state indicating a mechanical state of the electronic device 201, based on data received from the sensor module 276. For example, the processor 220 may determine (or calculate) an angle between a first surface of a first housing (e.g., the first housing 112 of FIG. 1) and a second surface of a second housing (e.g., the second housing 114 of FIG. 1) of the electronic device 201, based on at least one of an angle sensor, a strain sensor, a distance sensor, or a gyroscope sensor of the electronic device 201. According to an embodiment, the processor 220 may determine which one of a designated first angle range (e.g., 180 degrees), a designated second angle range (e.g., greater than 0 degree and less than 180 degrees), and a designated third angle range (e.g., 0 degree) the angle between the first surface of the first housing and the second surface of the second housing corresponds to. If the angle between the first surface of the first housing and the second surface of the second housing corresponds to the designated first angle range, the processor 220 may determine a folded out state of the electronic device 201. If the angle between the first surface of the first housing and the second surface of the second housing corresponds to the designated second angle range, the processor 220 may determine a folded in state of the electronic device 201. If the angle between the first surface of the first housing and the second surface of the second housing corresponds to the designated third angle range, the processor 220 may determine a closed state of the electronic device 201.

According to various embodiments, the processor 220 may control to provide any one of a first user interface or a second user interface corresponding to a running application based on the folding state of the electronic device. For example, the processor 220 may control to provide the first user interface corresponding to the running application if the electronic device is folded out, and control to provide one of the first user interface or the second user interface corresponding to the running application if the electronic device is folded in. The second user interface includes the same object as the first user interface, but a display position of at least one object may be different from the first user interface. For example, the first user interface may display at least one main object in a first area of the display, whereas the second user interface may display at least one main object in a second area which is a different area of the display. According to an embodiment, at least part of the second area may overlap at least part of the first area. According to an embodiment, the second area may not overlap the first area. According to an embodiment, the display area and/or the position of the at least one main object in the second user interface may be changed based on at least one of a grip mode of the electronic device, a position of a detected hovering input, a user preferred direction, or a mainly used direction.

According to various embodiments, if the electronic device is folded out, the processor 220 may control a display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2) to provide the first user interface corresponding to the running application. For example, if the electronic device is folded out and a home application is running, the processor 220 may control to display a first home screen on the display. For example, if the electronic device is folded out and a camera application is running, the processor 220 may control to display a first screen (e.g., a preview screen, a video recording screen, or a camera setting screen) of the camera application on the display. According to an embodiment, the first user interface corresponding to the running application may include at least one of an object or content. The object may include may include an item (e.g., a menu item, a popup window, a function button, or an icon) for triggering at least one designated function. According to an embodiment, the content may include at least one of an image or a text. For example, the first user interface (e.g., the first home screen) corresponding to the home application may include at least one of a home button, a back button, a recent use history button, at least one application icon, or a background image. For example, the first user interface (e.g., the first screen) corresponding to the camera application may include at least one of an image capturing button, a video recording button, a captured image view button, a shooting mode switch button, a flash setting button, a camera setting menu entry button, or preview images obtained from the camera module 280 in real time.

According to various embodiments, if the electronic device is changed from the folded out state to the folded in state, the processor 220 may determine whether to change the user interface, based on whether at least one main object exists in the first user interface corresponding to the running application. According to various embodiments, if the application is executed in the folded in state of the electronic device, the processor 220 may determine whether to maintain the first user interface or to switch to the second user interface, based on whether at least one main object exists in the first user interface corresponding to the running application. The main object may include at least one of an object displayed in a first area of the display in the folded out state of the electronic device 201, an object pre-designated by a designer, a designated object in the application, or an object of which use frequency exceeds a designated threshold. According to an embodiment, the first area of the display may include at least part of an area corresponding to the position of the folding portion 120 in the whole area of the display 130. For example, the first area of the display may be an area where a left area corresponding to the first surface and a right area corresponding to the second surface meets in the entire area of the display meet. The first area of the display may include at least part of the area corresponding to the folding portion of the display 130. The first area of the display may include at least part of the left area corresponding to the first surface of the display and at least part of the right area corresponding to the second surface of the display. The first area of the display may be set and/or changed by the designer and/or the user. According to an embodiment, if there is no at least one main object in the first user interface, the processor 220 may maintain the first user interface without changing the user interface. For example, if there is no at least one main object in the first user interface, the processor 220 may maintain the first user interface corresponding to the running application, in response to an event which changes the electronic device from the folded out state to the folded in state.

According to an embodiment, if at least one main object exists in the first user interface, the processor 220 may change the user interface for the running application from the first user interface to the second user interface. For example, by changing the display area (or position) of at least one main object in the first user interface, the processor 220 may provide the second user interface of the changed display area of the main object. For example, in response to an event which changes the electronic device from the folded out state to the folded in state, the processor 220 may move and display at least one main object of the first area to the second area. The second area may be a different area not overlapping the first area.

According to an embodiment, the processor 220 may determine the second area for displaying the moved main object, based on the grip mode of the electronic device 201 and/or the area of the detected hovering input. The grip mode may indicate whether the electronic device 201 is held with one hand or two hands. The grip mode may be divided into, for example, a one-hand grip mode and a two-hand grip mode. The processor 220 may determine the grip mode based on a contact area size or a contact position detected by a touch sensor. According to an embodiment, in the one-hand grip mode, the processor 220 may determine at least part of a display area corresponding to the grip surface of the first surface and the second surface of the electronic device 201, as the second area. For example, if the user grips the first surface, the processor 220 may determine at least part of an area not overlapping the first area in the left area of the display corresponding to the first surface, as the second area. For example, if the user grips the second surface, the processor 220 may determine at least part of an area not overlapping the first area in the right area of the display corresponding to the second surface, as the second area. According to an embodiment, in the two-hand grip mode, the processor 220 may determine the second area based on a user preferred direction. For example, the processor 220 may determine the user preferred direction based on a preset main object display direction or a mainly used direction, and determine the second area based on the determined user preferred direction. According to an embodiment, the processor 220 may request the user to preset the main object display direction for the two-hand grip mode, and preset the main object display direction based on a user input. The main object display direction may be set to one of a left direction, a right direction, an up direction, a down direction, a first direction, a second direction, or a bi-direction. If the preset main object display direction is the left direction in the two-hand grip mode, the processor 220 may determine at least partial area not overlapping the first area in the left area of the display corresponding to the first surface in the left direction based on a folding portion (e.g., the folding portion 120 of FIG. 1), as the second area. If the preset main object display direction is the bi-direction in the two-hand grip mode, the processor 220 may determine the second area in each of the left area and the second area of the display. For example, if the preset main object display direction is the bi-direction, the processor 220 may determine at least partial area not overlapping the first area in the left area of the display as the second area, and determine at least partial area not overlapping the first area in the right area of the display as the second area. If determining two second areas, the processor 220 may display the same main object in each of the second areas. According to an embodiment, the processor 220 may determine a direction mainly used by the user based on a shape change of the contact area detected by the touch sensor, or a hovering input detection position, and determine the second area based on the determined direction. For example, if the shape change of the contact area of the left direction of the display is more frequent than the shape change of the contact area of the right direction in the two-hand grip mode, the processor 220 may determine the right direction as the mainly used direction. For example, if hovering inputs detected in the left direction of the display are more than hovering inputs detected in the right direction of the display in the two-hand grip mode, the processor 220 may determine the left direction as the mainly used direction. The processor 220 may determine at least partial area not overlapping the first area of the display area corresponding to the surface of the mainly used direction based on the folding portion (e.g., the folding portion 120 of FIG. 1), as the second area. According to an embodiment, the main object display direction or the mainly used direction may be set and/or determined for each application. For example, the main object display direction for the home screen application may be set to the bi-direction, and the main object display direction for the camera application may be set to the right direction. For example, the mainly used direction for the home screen application may be set to the right direction, and the mainly used direction for the camera application may be set to the left direction. According to an embodiment, the mainly used direction may be re-determined (or updated) at a periodic or designated event occurrence. If the mainly used direction is changed, the processor 220 may change the second area which is the main object display area, based on the changed mainly used direction. For example, the processor 220 may determine the mainly used direction, based on the contact area shape changes and the hovering inputs which are accumulated for a preset time period. If the mainly used direction is changed, the processor 220 may re-determine the second area based on the changed mainly used direction, and control to display the main object in the re-determined second area.

According to an embodiment, the processor 220 may detect a state in which the user grips the first area where the first surface and the second surface meet (or a state in which a center area of the display is gripped). If detecting the gripped state of the first area, the processor 220 may detect the area for displaying the moved main object as the second area, based on at least one of the hand holding the first area (e.g., the left hand or the right hand) or the user preferred direction. According to an embodiment, the processor 220 may determine whether the first area of the display is gripped with the left hand or the right hand, based on at least one of a contact area position, a contact area size, or a contact area shape detected by the touch sensor. For example, if the first area of the display is gripped with the right hand, the processor 220 may determine at least partial area not overlapping the first area in the right area of the display, as the second area. If the first area of the display is gripped with the left hand, the processor 220 may determine at least partial area not overlapping the first area in the left area of the display, as the second area. According to an embodiment, the processor 220 may determine the user preferred direction based on a preset main object display direction for the first area grip state (or the center grip state) or the mainly used direction. By requesting the user to preset the main object display direction for the first area grip state, the processor 220 may preset the main object display direction for the first area grip state based on a user input. If the first area is gripped and the preset main object display direction for the first area grip state is the left direction, the processor 220 may determine at least partial area not overlapping the first area in the left area of the display, as the second area. The processor 220 may determine the direction mainly used by the user, based on the contact area shape change detected by the touch sensor, or a hovering input detection position. If the first area of the display is gripped and the mainly used direction is the right direction, the processor 220 may determine at least partial area not overlapping the first area in the right area of the display, as the second area. The examples of determining the second area if the first area is gripped are to ease the understanding, and the disclosure is not limited thereto.

According to an embodiment, the processor 220 may determine a position, a size and a shape of the second area, by further considering at least one of a sub-object display area in the first user interface corresponding to a running application, or a content display area. For example, the processor 220 may determine at least one of the position, the size and the shape of the second area, wherein the second area for displaying the moved main object does not overlap the sub-object display area. According to an embodiment, the sub-object may include at least one of an object displayed in other area than the first area of the display, an object designated by the designer as the sub-object, an object designated as the sub-object in the application, or an object of which a use frequency is lower than a designated threshold.

According to an embodiment, the processor 220 may adjust at least one of the position, the size and the shape of the sub-object, based on at least one of the position, the size, and the shape of the second area to which the main object is moved. For example, the processor 220 may adjust at least one of the position, the size and the shape of the sub-object, wherein a sub-object display area and a main object display area do not overlap. According to an embodiment, the processor 220 may adjust the display position of the sub-object to display the sub-object in the same direction as the main object. For example, the processor 220 may move the main object from the first area of the display to the left area of the display, and move the sub-object displayed in the right area of the display to the left area of the display. According to an embodiment, the processor 220 may control to display the sub-object in the same direction as the main direction, based on the use frequency of the sub-object. For example, if the use frequency of a first sub-object is higher than a designated use frequency, the processor 220 may control to display the first sub-object in the same direction as the main direction. For example, if the use frequency of the first sub-object is higher than the designated use frequency, the processor 220 may control to display the first sub-object in the same direction as the main direction by moving the main object from the first area of the display to the right area of the display and moving the first sub-object displayed in the left area of the display to the right area of the display. For example, if the use frequency of a second sub-object is lower than the designated use frequency, the processor 220 may maintain a display area of the second sub-object, regardless of the movement direction of the main object. For example, if the use frequency of the second sub-object is lower than the designated use frequency, the processor 220 may move the main object from the first area of the display to the right area of the display and maintain the second sub-object displayed in the left area of the display without changing it.

According to an embodiment, the processor 220 may adjust at least one of a size, a shape, or a color of at least one main object, based on the determined position, size, and shape of the second area. According to an embodiment, with a plurality of main objects, the processor 220 may change arrangement of the main objects based on the second area.

According to an embodiment, the processor 220 may provide an additional object allowing the user to directly change the main object display area. For example, if the main object is moved and displayed in other area than the first area of the display due to the folding state of the electronic device, the processor 220 may display an additional object allowing the user to change the display area and/or the direction of the main object. If the additional object is selected by a user input, the processor 220 may change the main object display area to an opposite area based on the folding portion 120. For example, if the additional object is selected with the main object displayed in the left area of the display based on the folding portion 120, the processor 220 may move and display the main object in the right area of the display based on the folding portion 120.

According to various embodiments, if detecting a designated gesture for the main object and/or the sub-object, the processor 220 may change the display area of the main object and/or the sub-object. The designated gesture may include at least one of, for example, drag, double touch, long touch, and press touch, which are exemplary. The designated gesture according to various embodiments of the disclosure is not limited thereto. According to an embodiment, if the main object and/or the sub-object is touched long and dragged, the processor 220 may change the display area of the main object and/or the sub-object based on the drag direction.

According to various embodiments, if the electronic device 201 is changed from the folded in state to the folded out state, the processor 220 may control to change the user interface for the running application from the second user interface to the first user interface.

Operations may be or may not be performed in order. For example, order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 5 are described by referring to FIGS. 6A and 6B.

FIGS. 6A and 6B are screen views for controlling a user interface based on a mechanical state change in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 5, an electronic device (e.g., the processor 220 of FIG. 2) according to various embodiments may provide a first user interface corresponding to a running application in an unfolding state (or a folded out state) in operation 501. According to an embodiment, the processor 220 may determine the angle between the first housing 112 and the second housing 114 of the electronic device 101 or 201, using at least one sensor (e.g., the first sensor 141 or the second sensor 142 of FIG. 1, or the sensor module 276 of FIG. 2), and determine whether the electronic device 101 or 201 is unfolded, based on the calculated angle. The unfolding state may indicate that the angle between the first housing 112 and the second housing 114 of the electronic device corresponds to a designated first angle range. The first angle range may include, for example, an angle greater than about 175 degrees and smaller than 185 degrees, which is exemplary to ease the understanding. Notably, the first angle range may be set and/or changed by the designer. According to an embodiment, if the electronic device is folded out, the processor 220 may control a display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2) to provide the first user interface corresponding to the running application. The first user interface corresponding to the running application may include at least one of an object or content. The object may include an item (e.g., a menu item, a popup window, a function button, or an icon) for triggering at least one function relating to the running application. According to an embodiment, the content may include at least one of an image or a text relating to the running application. For example, the first user interface corresponding to a home application may include at least one of a home button, a back button, a recent use history button, at least one application icon, or a background image. For example, the first user interface corresponding to a camera application may include at least one of an image capturing button, a video recording button, a captured image view button, a shooting mode switch button, a flash setting button, a camera setting menu entry button, or preview images obtained from the camera module 280 in real time. According to an embodiment, the first user interface corresponding to the running application may include at least one main object displayed in the first area of the display 130 or 260 with the electronic device 101 or 201 folded out. According to an embodiment, the first area of the display 130 or 260 may include at least part of an area corresponding to a position of a folding portion (e.g., the folding portion 120 of FIG. 1) of the whole area of the display 130 or 260. The first area of the display may be set and/or changed by the designer and/or the user. For example, the processor 220 may control to provide the first user interface displaying a main object 601 in a first area 610 of the display 130 as shown in FIG. 6A.

According to various embodiments, the electronic device (e.g., the processor 220) may detect a folding event in operation 503. According to an embodiment, the processor 220 may determine the angle between the first housing 112 and the second housing 114 of the electronic device 101 or 201, using at least one sensor (e.g., the first sensor 141, the second sensor 142, or the sensor module 276), and detect the folding state of the electronic device 101 or 201, based on the calculated angle. If the angle between the first housing 112 and the second housing 114 corresponds to a designated second angle range, the processor 220 may determine occurrence of the folding event. The second angle range may include, for example, an angle greater than about 5 degrees and smaller than 175 degrees, which is exemplary to ease the understanding. Notably, the second angle range may be set and/or changed by the designer.

According to various embodiments, the electronic device (e.g., the processor 220) may provide the second user interface corresponding to the running application in operation 505. According to an embodiment, in response to detecting folding event, the processor 220 may control a display (e.g., the display 130 or the display device 260) to provide the second user interface corresponding to the running application. According to an embodiment, if the electronic device 101 or 201 is folded in, the processor 220 may control the display (e.g., the display 130 or the display device 260) to provide the second user interface corresponding to the running application. The second user interface corresponding to the running application may include the same object as the first user interface but a display position of at least one main object may be different from the first user interface. For example, the first user interface displays the at least one main object 601 in the first area 610 of the display as shown in FIG. 6B, whereas the second user interface may display at least one main object 611 in the second area which is a different area of the display as shown in FIG. 6B. According to an embodiment, the processor 220 may determine the second area for displaying the main object, based on at least one of a grip mode of the electronic device 101 or 201, a hovering input detection position, a user preferred direction, or a mainly used direction. The second area may be determined to a different area not overlapping the first area in the whole area of the display 130 or 260. According to an embodiment, if the electronic device 101 or 201 is changed from the folded out state to the folded in state, the processor 220 may control the display 130 or 260 to provide an effect which moves at least one main object form the first area to the second area.

FIG. 7 is a flowchart 700 for controlling a user interface based on a grip mode in an electronic device according to an embodiment of the disclosure.

Operations of FIG. 7 may be at least part of detailed operations of operation 505 of FIG. 5. Operations may be or may not be performed in order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 7 are described by referring to FIGS. 8A to 8F.

FIGS. 8A, 8B, 8C, 8D, 8E, and 8F are screen views for controlling a user interface based on a grip mode in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 7, an electronic device (e.g., the processor 220 of FIG. 2) according to various embodiments may identify contact area and position in operation 701. According to an embodiment, the processor 220 may detect a user contact to the electronic device 101 or 201 using at least one sensor (e.g., the sensor module 276 of FIG. 2), and identify the detected contact area and contact position. For example, the processor 220 may identity the contact area and position of a user grip of the electronic device 101 or 201 using a touch sensor which is coupled to or embedded in a display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2).

According to various embodiments, the electronic device (e.g., the processor 220) may determine whether it is in the one-hand grip mode in operation 703. According to an embodiment, the processor 220 may determine the grip mode based on the contact area size and/or the contact position detected using at least one sensor (e.g., the sensor module 276 of FIG. 2). For example, if the user contact is detected only in an area corresponding to a first housing (e.g., the first housing 112 of FIG. 1) of the whole area of the display 130 and the size of the detected contact area is greater than a threshold size, the processor 220 may determine the one-hand grip mode in which the first housing is gripped. For example, if the user contact is detected only in an area corresponding to a second housing (e.g., the second housing 114 of FIG. 1) of the whole area of the display 130 and the size of the detected contact area is greater than the threshold size, the processor 220 may determine the one-hand grip mode in which the second housing is gripped. For example, if the user contact is detected in each of the area corresponding to the first housing 112 and the area corresponding to the second housing 114 of the whole area of the display 130 and the size of each detected contact area is greater than the threshold size, the processor 220 may determine the two-hand grip mode in which both of the first housing and the second housing are gripped. For example, if the user contact is detected in each of the area corresponding to the first housing 112 and the area corresponding to the second housing 114 of the whole area of the display 130 but the size of the detected contact area in the area corresponding to the first housing 112 is greater than the threshold size and the size of the detected contact area in the area corresponding to the second housing 114 is smaller than the threshold size, the processor 220 may determine the one-hand grip mode in which the first housing is gripped. For example, if the contact area size is smaller than the threshold size, the processor 220 may process the corresponding contact as a non-grip touch input.

According to various embodiments, in the one-hand grip mode, the electronic device (e.g., the processor 220) may determine a second area based on the grip direction and/or a hovering input in operation 705, and display at least one main object in the second area in operation 709. According to an embodiment, in the one-hand grip mode, the processor 220 may determine at least one partial area of a surface corresponding to the grip direction in the first surface of the display 130 corresponding to the first housing 112 and the second surface of the display 130 corresponding to the second housing 114, as the second area. For example, if the user grips the first housing 112, the processor 220 may determine at least partial area not overlapping the first area in the left area of the display corresponding to the first surface, as the second area. For example, if the user grips the second housing 114, the processor 220 may determine at least partial area not overlapping the first area in the right area of the display corresponding to the second surface, as the second area. According to an embodiment, in the one-hand grip mode, the processor 220 may determine at least one partial area of the surface of the detected hovering input in the first surface of the display 130 corresponding to the first housing 112 and the second surface of the display 130 corresponding to the second housing 114, as the second area. According to an embodiment, the processor 220 may move and display at least one main object in the determined second area. For example, if a left portion of the electronic device 101 or 201 is gripped and the electronic device 101 or 201 is folded, the processor 220 may display objects 801, 811, and 821 displayed at the bottom including at least part of the first area in the folded out state, in second areas 803, 813, and 823 which are part of the left surface as shown in FIGS. 8A, 8B, and 8C. For example, if a right portion of the electronic device 101 or 201 is gripped and the electronic device 101 or 201 is folded, the processor 220 may display the objects 801, 811, and 821 displayed at the bottom including at least part of the first area in the folded out state, in second areas 805, 815, and 825 which are part of the right surface as shown in FIGS. 8A, 8B, and 8C.

According to various embodiments, in the two-hand grip mode, the electronic device (e.g., the processor 220) may determine the second area based on the user preferred direction in operation 707, and display at least one main object in the second area in operation 709. According to an embodiment, in the two-hand grip mode, the processor 220 may determine the user preferred direction based on a preset main object display direction or a mainly used direction, and determine the second area based on the determined user preferred direction. According to an embodiment, the processor 220 may determine the direction mainly used by the user based on a shape change of the contact area detected by the touch sensor or a hovering input detection position, and determine the mainly used direction as the user preferred direction. The processor 220 may request the user to preset the main object display direction for the two-hand grip mode, and preset the main object display direction based on a user input. The processor 220 may determine the preset main object display direction as the user preferred direction. According to an embodiment, if the user preferred direction is the left direction in the two-hand grip mode, the processor 220 may determine at least part of the left area of the display based on a folding portion (e.g., the folding portion 120 of FIG. 1), as the second area, and control a display (e.g., the display 130 or the display device 260) to display a main object in the second area. For example, as shown in FIG. 8D, if both side portions of the electronic device 101 or 201 are gripped and the electronic device 101 or 201 is folded in, the processor 220 may display objects 831 displayed at the bottom including at least part of the first area in the folded out state, in a second area 833 which is part of the right surface corresponding to the user preferred direction. According to an embodiment, if the user preferred direction is both directions in the two-hand grip mode, the processor 220 may determine the second area in each of the left area and the right area of the display and control the display (e.g., the display 130 or the display device 260) to display a main object in the two second areas of the left area and the right area. For example, as shown in FIG. 8E, if both side portions of the electronic device 101 or 201 are gripped and the electronic device 101 or 201 is folded in, the processor 220 may display objects 841 displayed at the bottom including at least part of the first area in the folded out state, in second areas 843 and 845 which are part of the both surfaces (the first surface and the second surface). For example, as shown in FIG. 8F, if both side portions of the electronic device 101 or 201 are gripped and the electronic device 101 or 201 is folded in, the processor 220 may display an object placed in the first area among objects 851 displayed at the bottom in the folded out state, in second areas 853 and 855 which are part of the both surfaces.

FIG. 9 is a flowchart 900 for controlling a user interface based on a designated condition in an electronic device according to an embodiment of the disclosure.

Operations of FIG. 9 may be at least part of detailed operations of operation 707 and operation 709 of FIG. 7. Operations may be or may not be performed in order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 9 shall be described by referring to FIGS. 10A and 10B. FIGS. 10A and 10B are screen views for controlling a user interface based on a designated condition in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 9, an electronic device (e.g., the processor 220 of FIG. 2) may determine whether a designated condition is satisfied in operation 901. According to an embodiment, the designated condition may include a condition of whether a designated main object is included in the first user interface. For example, the processor 220 may determine whether the main object designated to display on both surfaces in the two-hand grip mode exists in at least one object of the first user interface of a running application. If the main object designated to display on both surfaces in the two-hand grip mode is included in the first user interface, the processor 220 may determine that the designated condition is satisfied. If the main object designated to display on both surfaces in the two-hand grip mode is not included in the first user interface, the processor 220 may determine that the designated condition is not satisfied. According to an embodiment, the designated condition may include a condition of whether the running application is a designated application. For example, the processor 220 may determine whether the running application is an application designated to display the main object on both surfaces in the two-hand grip mode. The processor 220 may determine whether the corresponding application is the application designated to display the main object on both surfaces in the two-hand grip mode, based on at least one of a type of the running application, application identification information, or application functionality. For example, if the application designated to display the main object on both surfaces in the two-hand grip mode matches the running application in type, the processor 220 may determine that the designated condition is satisfied. For example, if the application designated to display the main object on both surfaces in the two-hand grip mode does not match the running application in type, the processor 220 may determine that the designated condition is not satisfied. According to an embodiment, the designated condition may include a condition on a use frequency or a use count of the main object included in the first user interface. For example, the processor 220 may determine whether a main object which is used over a threshold count during a preset time period exists in at least one object of the first user interface of the running application. If at least one main object of the first user interface of the running application is used over the threshold count, the processor 220 may determine that the designated condition is satisfied. If main objects of the first user interface of the running application are used in a number of times which is smaller than or equal to the threshold count, the processor 220 may determine that the designated condition is not satisfied.

According to various embodiments, if the designated condition is satisfied, the electronic device (e.g., the processor 220) may determine two second areas in operation 903, and display a main object in each of the two determined areas in operation 905. According to an embodiment, the processor 220 may determine at least part of the first surface of the electronic device 101 or 201 as the second area, determine at least part of the second surface as the second area, and control the display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2) to display at least one main object in each of the two determined second areas. The second area of the first surface and the second area of the second surface may face each other if the electronic device 101 or 201 is closed. The main object displayed in each of the two second areas may include an object to be displayed on both surfaces in the two-hand grip mode. For example, as shown in FIG. 10A, if a home button object of objects 1001 of the first user interface is used over a threshold count, the processor 220 may control to display the home button object in each of a second area 1003 of the first surface and a second area 1005 of the second surface. For example, as shown in FIG. 10B, if a call end button object 1011 of objects of the first user interface corresponding to a call application is a designated object to be displayed on both surfaces in the two-hand grip mode, the processor 220 may control to display the call end button object in each of a second area 1013 of the first surface and a second area 1015 of the second surface.

According to various embodiments, if the designated condition is not satisfied, the electronic device (e.g., the processor 220) may determine one second area in operation 911, and display a main object in the determined second area in operation 913. According to an embodiment, the processor 220 may determine at least part of one of the first surface and the second surface of the electronic device 101 or 201 as the second area, and control the display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2) to display at least one main object in the determined second area. The processor 220 may select one of the first surface and the second surface based on the user preferred direction, and determine at least part of the selected surface as the second area. For example, as shown in FIG. 10B, if the first user interface corresponding to the call application includes main objects 1031 not designated to display on both surfaces in the two-hand grip mode, the processor 220 may control to move and display the corresponding main objects 1031 in a second area 1021 of the first surface based on the user preferred direction. According to an embodiment, if the second area 1021 of the first surface includes sub-objects, the processor 220 may control to display the sub-objects not to overlap the main objects, by adjusting a display position and/or a size of the sub-objects.

FIG. 11 is a flowchart 1100 for controlling a user interface based on a mainly used surface in an electronic device according to an embodiment of the disclosure.

Operations of FIG. 11 may be at least part of detailed operations of operation 707 of FIG. 7. The operations may be or may not be performed in order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 11 shall be described by referring to FIGS. 12A and 12B.

FIGS. 12A and 12B are screen views for controlling a user interface based on a mainly used surface in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 11, the electronic device (e.g., the processor 220) according to various embodiments may determine the mainly used direction based on a hovering input and a contact area shape change in operation 1101. According to an embodiment, the processor 220 may determine the direction mainly used by the user, based on the contact area shape change detected by the touch sensor or the hovering input detection position. For example, if the contact area shape change of the left direction of the display is more frequent than the contact area shape change of the right direction in the two-hand grip mode, the processor 220 may determine the right direction as the mainly used direction. For example, if the number of hovering inputs detected on the first surface in the left direction is greater than the number of hovering inputs detected on the second surface in the right direction in the two-hand grip mode, the processor 220 may determine the left direction as the mainly used direction.

According to various embodiments, the electronic device (e.g., the processor 220) may determine whether a mainly used surface corresponding to the mainly used direction matches the surface of the second area in operation 1103. For example, based on whether the mainly used surface matches the surface of the second area, the processor 220 may determine whether the main object is displayed in the mainly used surface. If the mainly used surface matches the surface of the second area, the processor 220 may determine that the main object is displayed in the mainly used surface. If the mainly used surface does not match the surface of the second area, the processor 220 may determine that the main object is not displayed in the mainly used surface.

According to various embodiments, if the mainly used surface matches the surface of the second area, the electronic device (e.g., the processor 220) may control a display (e.g., the display 130 of FIG. 1 or the display device 260 of FIG. 2) to maintain the main object display in operation 1105. For example, if the mainly used surface matches the surface of the second area, the main object is displayed in the mainly used surface and accordingly the processor 220 may maintain the main object display. For example, as shown in FIG. 12A, if a play button 1201 which is the main object is displayed in the second surface and the mainly used surface is the second surface of the right direction, the play button 1201 is displayed in the mainly used surface and accordingly the processor 220 may maintain the display of the main object.

According to various embodiments, if the mainly used surface does not match the surface of the second area, the electronic device (e.g., the processor 220) may change the second area to at least part of the mainly used surface in operation 1107, and display the main object in the changed second area in operation 1109. For example, if the mainly used surface does not match the surface of the second area, the main object is not displayed in the mainly used surface and accordingly the processor 220 may determine at least part of the mainly used surface as the second area and thus move and display the main objet in the mainly used surface. For example, as shown in FIG. 12B, if a play button 1211 which is the main object is displayed in the second surface and the mainly used surface is the first surface of the left direction, the processor 220 may control to display a play button 1213 in part of the mainly used surface.

FIG. 13 is a flowchart 1300 for controlling a user interface based on an object use frequency in an electronic device according to an embodiment of the disclosure.

Operations of FIG. 13 may be at least part of detailed operations of operation 505 of FIG. 5. The operations may be or may not be performed in order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 13 shall be described by referring to FIG. 14.

FIG. 14 is a screen view for controlling a user interface based on a use frequency in an electronic device according to an embodiment of the disclosure.

Referring to FIG. 13, the electronic device (e.g., the processor 220) according to various embodiments may determine whether a sub-object exists in the first user interface in operation 1301. According to an embodiment, the sub-object may include at least one of an object displayed in other area than the first area of the display, an object designated by the designer as the sub-object, an object designated as the sub-object in an application, or an object not designated as a main object. For example, the processor 220 may determine whether the first user interface corresponding to a running application includes at least one sub-object.

According to various embodiments, the electronic device (e.g., the processor 220) may compare a use frequency of the sub-object with a designated threshold and determine whether the use frequency of the sub-object is greater than the designated threshold in operation 1303. According to an embodiment, the use frequency of the sub-object may be calculated by accumulating the use count during a preset time period in the electronic device 101 or 201.

According to various embodiments, if the use frequency of the sub-object is smaller than or equal to the designated threshold, the electronic device (e.g., the processor 220) may maintain the display of the sub-object in operation 1311. According to an embodiment, if the use frequency of the sub-object is smaller than or equal to the designated threshold, the use frequency of the sub-object is low and accordingly the processor 220 may maintain the same display position of the sub-object of the second user interface as the display position of the sub-object of the first user interface. For example, as shown in FIG. 14, if a record button 1401 which is the sub-object is included in the first user interface corresponding to a camera application and the use frequency of the record button 1401 is smaller than the threshold, in response to detecting a folding event, the processor 220 may move and display an image capture button 1405 being the main object in the second surface which is gripped and control not to change the display position of the record button 1403 which is the sub-object.

According to various embodiments, if the use frequency of the sub-object is greater than the designated threshold, the electronic device (e.g., the processor 220) may determine a third area to which the sub-object is moved, based on the second area which is the move area of the main object in operation 1305, and display the sub-object in the third area in operation 1307. According to an embodiment, if the use frequency of the sub-object is greater than the designated threshold, the use frequency of the sub-object is high and accordingly the processor 220 may determine the display area of the sub-object by considering the display area of the main object of the second user interface. For example, the processor 220 may determine the third area which is the display area of the sub-object, to display the sub-object having the use frequency greater than the threshold in the same surface as the main object. For example, as shown in FIG. 14, if the record button 1401 being the sub-object is included in the first user interface corresponding to the camera application and the use frequency of the record button 1401 is greater than the threshold, in response to detecting a folding event, the processor 220 may move and display the image capture button 1405 being the main object and a record button 1413 being the sub-object in the second surface which is gripped.

While it has been described that the display position of the sub-object in the user interface is controlled based on the use frequency in FIG. 13, the main object may be controlled in the same manner according to various embodiments. For example, if the use frequency of the main object is smaller than or equal to the threshold, the display position of the main object may be maintained in detecting the folding event. For example, if the use frequency of the main object is greater than the threshold, the display position of the main object in detecting the folding event may be changed according to the grip mode as mentioned in FIG. 7.

FIG. 15 is a flowchart 1500 for controlling a changed user interface based on a mechanical state change in an electronic device according to an embodiment of the disclosure.

Operations of FIG. 15 may be at least part of detailed operations of operations 705 and 707 of FIG. 7. The operations may be or may not be performed in order. For example, the order of the operations may be changed, and at least two operations may be performed in parallel. Herein, the electronic device may be the electronic device 101 of FIG. 1 and/or the electronic device 201 of FIG. 2. Now, at least some of the operations of FIG. 15 shall be described by referring to FIGS. 16A and 16B.

FIGS. 16A and 16B are screen views for controlling a changed user interface based on a mechanical state change in an electronic device according to various embodiments of the disclosure.

Referring to FIG. 15, the electronic device (e.g., the processor 220) according to various embodiments may display a main object in the second area and display an additional object for changing the main object display area in operation 1501. According to an embodiment, if the electronic device 101 or 201 is folded in the two-hand grip mode, the processor 220 may display the main object in the second area based on the user preferred direction and display the additional object for changing the main object display area. The additional object may be an object for moving the main object display area from the current display surface of the main object to other surface. The additional object may be displayed in other surface than the display surface of the main object. The additional object display surface may be determined based on the main object display area and/or the main object display surface, by way of example. However, the additional object display surface may be changed based on a design and/or user's setting. For example, as shown in FIG. 16A, if the electronic device 101 or 201 is folded in the two-hand grip mode, the processor 220 may display a main object 1611 in the second area of the second surface based on the user preferred direction and display an additional object 1603 for changing the display area of the main object 1611. For example, as shown in FIG. 16B, if the electronic device 101 or 201 is folded in the two-hand grip mode, the processor 220 may display a main object 1613 in the second area of the first surface based on the user preferred direction and display an additional object 1603 for changing the display area of the main object 1613.

According to various embodiments, the electronic device (e.g., the processor 220 may detect selection on the additional object in operation 1503. According to an embodiment, the processor 220 may detect a user touch input for selecting the additional object.

According to various embodiments, the electronic device (e.g., the processor 220) may change the display area of the main object in operation 1505. According to an embodiment, in response to the additional object selection, the processor 220 may move and display the main object from the current display surface to other surface area. According to an embodiment, the processor 220 may change the display area of the additional object based on the changed main object display area. For example, as shown in FIG. 16A, if the main object 1611 is displayed in the second surface and a user input to the additional object 1601 is detected while the additional object 1601 is displayed in the first surface, the processor 220 may control a display (e.g., the display 130 or the display device 260) to display the main object 1613 in the first surface and to display the additional object 1603 in the second surface.

According to various embodiments, an operating method of an electronic device may include detecting a folding angle of the electronic device using at least one sensor circuit, if the determined angle corresponds to a designated first range, displaying a first user interface corresponding to a running application, and if the determined angle corresponds to a designated second range, displaying a second user interface corresponding to the running application, wherein the second user interface may include the same object as the first user interface, and displays at least one object displayed in a first area, in a second area in the first user interface, the first area may include a partial area corresponding to a position of a hinge in a whole area of a flexible display, and the second area may be a different area from the first area.

According to various embodiments, displaying the second user interface may include determining the second area, based on at least one of a contact area detected through the at least one sensor circuit and a hovering input detection area.

According to various embodiments, displaying the second user interface may further include determining a grip mode based on the contact area detected through the at least one sensor circuit, and determining the second area, based on at least one of the grip mode, a grip direction, a hovering input detection direction, or a user preferred direction, wherein the grip mode may include at least one of a one-hand grip mode or a two-hand grip mode.

According to various embodiments, in the one-hand grip mode, the second area may be determined based on at least one of the grip direction or the hovering input detection direction.

According to various embodiments, in the two-hand grip mode, the second area may be determined based on the user preferred direction, and the user preferred direction may include at least one of an object display direction pre-designated by a user or a mainly used direction.

According to various embodiments, the mainly used direction may be determined based on a hovering input detected for a designated time duration or a contact area shape change.

According to various embodiments, displaying the second user interface may include identifying at least one sub-object in the first user interface, and adjusting a display position of the at least one sub-object in the second user interface, based on a use frequency of the identified sub-object, wherein the sub-object may include an object displayed in other area than the first area in the first user interface.

According to various embodiments, the second user interface may include an additional object for changing a display area of at least on object in the second user interface.

According to various embodiments, an electronic device of a foldable type may change a display position of at least one object based on a mechanical state change, and thus provide improved usability.
