Description

DISPLAY REGION TRANSFERAL FOLDING INPUT

TECHNICAL FIELD

[0001] The present application relates generally to a user interface.

BACKGROUND

[0002] As electronic apparatuses become more prolific, the amount of activities that a user may perform with the apparatus is increasing. For example, many users interact with their apparatuses in manners that, in the past, were unassociated with an electronic apparatus. For example, many users interact with interface items, such as icons, text, etc. that represent data objects governed by the apparatus. It may be desirable to allow a user to manage such interface items in a simple and intuitive manner.

Communication device 15 may operate in accordance with wireline protocols, such as Ethernet, digital subscriber line (DSL), asynchronous transfer mode (ATM), and/or the like.

[0073] Processor 11 may comprise means, such as circuitry, for implementing audio, video, communication, navigation, logic functions, and/or the like, as well as for implementing embodiments of the invention including, for example, one or more of the functions described herein. For example, processor 11 may comprise means, such as a digital signal processor device, a microprocessor device, various analog to digital converters, digital to analog converters, processing circuitry and other support circuits, for performing various functions including, for example, one or more of the functions described herein. The apparatus may perform control and signal processing functions of the electronic apparatus 10 among these devices according to their respective capabilities. The processor 11 thus may comprise the functionality to encode and interleave message and data prior to modulation and transmission. The processor 1 may additionally comprise an internal voice coder, and may comprise an internal data modem. Further, the processor 11 may comprise functionality to operate one or more software programs, which may be stored in memory and which may, among other things, cause the processor 11 to implement at least one embodiment including, for example, one or more of the functions described herein. For example, the processor 11 may operate a connectivity program, such as a conventional internet browser.

In at least one example embodiment, the apparatus causes display of information, the causation of display may comprise displaying the information on a display comprised by the apparatus, sending the information to a separate apparatus that comprises a display, and/or the like. The electronic apparatus may comprise an input device 13. Input device 13 may comprise a light sensor, a proximity sensor, a microphone, a touch sensor, a force sensor, a button, a keypad, a motion sensor, a magnetic field sensor, a camera, and/or the like. A touch sensor and a display may be characterized as a touch display. In an embodiment comprising a touch display, the touch display may be configured to receive input from a single point of contact, multiple points of contact, and/or the like. In such an embodiment, the touch display and/or the processor may determine input based, at least in part, on position, motion, speed, contact area, and/or the like. In at least one example embodiment, the apparatus receives an indication of an input. The apparatus may receive the indication from a sensor, a driver, a separate apparatus, and/or the like. The information indicative of the input may relate to information that conveys information indicative of the input, indicative of an aspect of the input indicative of occurrence of the input, and/or the like.

[0075] The electronic apparatus 10 may include any of a variety of touch displays including those that are configured to enable touch recognition by any of resistive, capacitive, infrared, strain gauge, surface wave, optical imaging, dispersive signal technology, acoustic pulse recognition or other techniques, and to then provide signals indicative of the location and other parameters associated with the touch. Additionally, the touch display may be configured to receive an indication of an input in the form of a touch event which may be defined as an actual physical contact between a selection object (e.g., a finger, stylus, pen, pencil, or other pointing device) and the touch display. Alternatively, a touch event may be defined as bringing the selection object in proximity to the touch display, hovering over a displayed object or approaching an object within a predefined distance, even though physical contact is not made with the touch display. As such, a touch input may comprise any input that is detected by a touch display including touch events that involve actual physical contact and touch events that do not involve physical contact but that are otherwise detected by the touch display, such as a result of the proximity of the selection object to the touch display. A touch display may be capable of receiving information associated with force applied to the touch screen in relation to the touch input. For example, the touch screen may differentiate between a heavy press touch input and a light press touch input. In at least one example embodiment, a display may display two-dimensional information, three-dimensional information and/or the like.

[0076] In embodiments including a keypad, the keypad may comprise numeric (for example, 0-9) keys, symbol keys (for example, #, *), alphabetic keys, and/or the like for operating the electronic apparatus 10. For example, the keypad may comprise a conventional QWERTY keypad arrangement. The keypad may also comprise various soft keys with associated functions. In addition, or alternatively, the electronic apparatus 10 may comprise an interface device such as a joystick or other user input interface.

[0077] Input device 13 may comprise a media capturing element. The media capturing element may be any means for capturing an image, video, and/or audio for storage, display or transmission. For example, in at least one example embodiment in which the media capturing element is a camera module, the camera module may comprise a digital camera which may form a digital image file from a captured image. As such, the camera module may comprise hardware, such as a lens or other optical component(s), and/or software necessary for creating a digital image file from a captured image.

Alternatively, the camera module may comprise only the hardware for viewing an image, while a memory device of the electronic apparatus 10 stores instructions for execution by the processor 11 in the form of software for creating a digital image file from a captured image. In at least one example embodiment, the camera module may further comprise a processing element such as a co-processor that assists the processor 11 in processing image data and an encoder and/or decoder for compressing and/or decompressing image data. The encoder and/or decoder may encode and/or decode according to a standard format, for example, a Joint Photographic Experts Group (JPEG) standard format.

[0078] FIGURES 2A-2E are diagrams illustrating an angle between a first display region and a second display region according to at least one example embodiment. The examples of FIGURES 2A-2E are merely examples and do not limit the scope of the claims. For example, orientation of the displays may vary, number of displays may vary, placement of the displays may vary, and/or the like.

[0079] As electronic apparatuses have evolved, and users have become increasingly dependent upon such apparatuses in performing many tasks, the importance of display area has increased. The importance of display area has become further enhanced by the widespread adoption of touch displays for apparatus interaction. However, there is also a driving force in the market for apparatuses to be portable. Therefore, there may often be a desire for the form factor of the apparatus to be small. At least one approach for addressing this seemingly conflicting desire for large display area and small form factor relates to providing apparatuses with multiple displays, where the housing is designed to be configured in various arrangements. For example, such an apparatus may relate to a folding apparatus form factor that allows use of more than one display in at least one configuration and a more compact form factor in a different configuration.

[0080] In some circumstances, it may be desirable to monitor the angle between such displays as the apparatus varies its configuration. For example, the apparatus may evaluate an angle between two or more displays, and perform various operations based, at least in part, on the angle.

[0081] In at least one example embodiment, an apparatus may be associated with a plurality of displays. For example, the apparatus may comprise a plurality of displays, may be in communication with a plurality of displays, may comprise one or more displays and be in communication with one or more displays, and/or the like. In such an example, the apparatus may be configured to detect an angle between at least two such displays. For example, the apparatus may comprise, or be in communication with, a sensor that is configured to provide information indicative of the angle between the displays. For example, the sensor may be a potentiometer, and encoder, and/or the like. In this manner, the apparatus may be configured to determine the angle between displays at various times and under various circumstances.

[0082] In some circumstances, a display region may be identified with a particular display. For example, an apparatus may comprise multiple displays. In such an example, there may be a distinct display region that corresponds with each display. For example, a first display region may be a first display and a second display region may be a second display. In some circumstances, a flexible display may comprise multiple display regions that are associated with regions of the display between which the display is folded. For example, a flexible display may be folded such that a display region exists on a side of the fold, and a different display region exists on an opposite side of the fold. In this manner, the fold may be a demarcation between the a first display region and a second display region.

[0083] In at least one example embodiment, the apparatus may be configured such that a first display region and a second display region are simultaneously viewable at a particular angle. In this manner, the apparatus may be configured to allow a user to interact with the first display region in conjunction with the second display region. For example, the user may interact with elements displayed on the first display region in conjunction with interaction with elements displayed on the second display region. In at least one example embodiment, an angle between the first display region and the second display region relates to an angle between a viewable part of the first display region and a viewable part of the second display region. In at least one example embodiment, a viewable part of a display region relates to a surface of the display region upon which information displayed by the display region may be seen.

[0084] The examples of FIGURES 2A-2E relate to apparatus 202, which comprises displays 204 and 206, which are foldably attached at hinge 208. FIGURE 2A is a diagram illustrating angle 210 between display region 204 and display region 206 according to at least one example embodiment. It can be seen that angle 210 relates to an angle of approximately 180 degrees.

[0085] FIGURE 2B is a diagram illustrating angle 220 between display region 204 and display region 206 according to at least one example embodiment. It can be seen that angle 220 relates to an angle of approximately 150 degrees.

[0086] FIGURE 2C is a diagram illustrating angle 230 between display region 204 and display region 206 according to at least one example embodiment. It can be seen that angle 230 relates to an angle of approximately 100 degrees.

[0087] FIGURE 2D is a diagram illustrating angle 240 between display region 204 and display region 206 according to at least one example embodiment. It can be seen that angle 240 relates to an angle of approximately 45 degrees.

[0088] FIGURE 2E is a diagram illustrating angle 250 between display region

204 and display region 206 according to at least one example embodiment. It can be seen that angle 250 relates to an angle of approximately 0 degrees. In at least one example embodiment, the configuration illustrated in FIGURE 2E may relate to an apparatus in a closed position. For example, the closed position of an apparatus may be characterized by displays of the apparatus facing each other in a way that allows the separate housings of the displays to be handled together by the user as a single housing. For example, the apparatus may be configured such that, in the closed position, the housing of display region 204 protects the face of display region 206, and the housing of display region 206 protects the face of display region 204.

[0089] In some circumstances, the apparatus may interpret a change of the angle between displays as a particular input. For example, the apparatus may receive

information indicative of the angle, information indicative of a change of the angle, and/or the like, and interpret the information as an input. The apparatus may perform an operation based, at least in part, on such an input. For example, the apparatus may perform an operation based, at least in part, on a change from angle 220 to angle 230.

[0090] FIGURES 3A-3B are diagrams illustrating transferal operations associated with a first display region and a second display region according to at least one example embodiment. The examples of FIGURES 3A-3B are merely examples and do not limit the scope of the claims. For example, position of one or more interface items may vary, number of interface items may vary, orientation of displays may vary, and/or the like.

[0091] There are various interface paradigms that may be possible by way of utilization of multiple displays. For example, paradigms may take advantage of a user's awareness of the displays as distinct displays. For example, it may be easier for a user to perceive a functional difference between information that is displayed on a first display region versus information that is displayed on a second display region. In this manner, the user's perception of the physical distinctiveness of the displays may play a role in the manner in which the apparatus interacts with the user. For example, information displayed on a first display region may be associated with different utilization than information displayed on a second display region. In such an example, information displayed on the first display region may relate to individual interface items without regard for any interrelationship between the interface items, and information displayed on the second display region may relate to interface items comprised by a particular collection of items. In at least one example embodiment, an interface item relates to a visual representation of a software object, such as a program, a file, a contact, a song, a video, and/or the like.

[0092] In at least one example embodiment, the apparatus allows selection of one or more interface items. Selection may relate to the apparatus receiving an input indicative of designation of the interface item. Such designation of the interface item may relate to designation of the interface item for an operation. In at least one example embodiment, the apparatus identifies an interface item to be selected based, at least in part, on a selection input. The selection input may be an input that identifies the interface item for selection. For example, the selection input may relate to a touch input, a cursor input, and/or the like. The cursor input may relate to an input associated with a cursor that has a position that corresponds with a position of the interface item. For example, the cursor may be a cursor controlled by way of a mouse, a directional keypad, a touch sensor, and/or the like. The touch input may relate to a touch input that has a position that corresponds with a position of the interface item. For example, the touch input may be a touch input of a touch display.

[0093] The apparatus may display an interface item at a position on the display. For example, the apparatus may display the interface item at a designated position, may change the position at which an interface item is displayed to a different position, and/or the like.

[0094] In at least one example embodiment, it may be desirable to transfer information based, at least in part, on an input indicative of transferal of an interface item from a display region to a different display region. For example, the transfer may relate to the interface item being relocated from the display region to the different display region, may relate to information associated with the interface item becoming associated with information of an interface item of the different display region, and/or the like. Even though causation of association between information of the interface item and information of a different interface item may not necessarily relate to a visual or informational transfer, such association may be characterized as a transfer by way of a change in the manner in which the information may be accessed, found, used, etc. For example, causation of an association between a song represented by a first interface item and a playlist represented by a second interface item may be referred to as a transfer by way of the conceptual relationship of the song being part of a list of songs associated with the playlist.

[0095] There may be many different types of inputs that may cause such transferal. Such inputs may be referred to as transferal inputs. For example, the user may perform a drag input in relation to the interface item, such that the drag input terminates on the different display region. In another example, there may be menu item that the user may select for causing such a transferal. In at least one example embodiment, it may be desirable for the apparatus to utilize the angle between the display region and the different display region as a transferal input. In at least one example embodiment, a transferal input that is based, at least in part, on an angle between at least two display regions is referred to as a display transferal folding input. The angle may relate to an angle between two display regions that are associated with different displays that are configurable with respect to the angle between them. For example, there may be a hinge between the displays that allows for change of angle between the displays. In another example, the display regions may be parts of a flexible display such that the display may be folded between the display regions. It may be desirable to utilize a display region transferal folding input as a transferal input due to the user's natural identification of the physical distinction or separation of the display region from the other display region. In this manner, the user may readily identify the interface items of the display region as being different from interface items of the different display region, based, at least in part, on the physical difference of the displays. By utilizing a change of angle as a transferal input, it allows the user to associate a physical action with the transferal that is performed by the apparatus. In this manner, the performance of the physical action in relation with the transferal allows the user to more easily understand the transferal operation, more easily remember the input that causes transferal, and/or the like.

[0096] In at least one example embodiment, the apparatus receives a display region transferal unfolding input. A display region transferal unfolding input may relate to change of angle between a display region and a different display region from a lesser angle to a greater angle. In this manner, a display region transferal unfolding input may be an input that is the opposite of a display region transferal folding input.

[0097] In at least one example embodiment, the apparatus receives information indicative of a display region transferal folding input, and performs a transferal operation based, at least in part, on the display region transferal folding input. In at least one example embodiment the display region transferal folding input may relate to a change from a first angle to a second angle, such that the second angle is less than the first angle. In this manner, the display region transferal folding input may relate to a change in angle towards a closed position, to a closed position, and/or the like. In some circumstances, the apparatus may perform the transfer operation on more than one interface item. For example, if there is a plurality of selected interface items, the apparatus may perform the transfer operation for each of the plurality of selected interface items. In at least one example embodiment, the apparatus determines an input to be a display region transferal folding input based, at least in part, on the initial angle between the displays being greater than ninety degrees. For example, the apparatus may determine that a change from angle 240 of FIGURE 2D to angle 250 of FIGURE 2E fails to relate to a display region transferal folding input. In at least one example embodiment, the apparatus may determine that a change in angle between displays that decreases the angle relates to a display region transferal folding input. For example, the apparatus may determine that a change from angle 220 of FIGURE 2B to angle 230 of FIGURE 2C relates to a display region transferal folding input. In another example, the apparatus may determine that a change from angle 230 of FIGURE 2C to angle 220 of FIGURE 2B fails to relate to a display region transferal folding input.

[0098] It has been shown that many users find interfaces to be more intuitive, and find inputs easier to remember and understand, when the inputs relate to physical activities that the user performs outside of the use of the apparatus. For example, users may perform fewer accidental inputs, may learn an interface more quickly, and/or the like, if the inputs of the interface are similar to physical manipulations with which the user may already be familiar. In this manner, the change of angle between the displays may be an intuitive input for, at least, the reason that the angle may relate to physical transferals that the user may already be familiar with. For example, the user may be familiar with wet ink on one page of a book being transferred to an opposing page when the book is closed. Similarly, the user may be familiar with tilting a wet object so that gravity pulls the liquid to a lower part of the object. In this manner, the display region transferal folding inputs may be a simple and intuitive manner for a user to cause transferal operations.

[0099] In performance of the transferal operation, the apparatus may determine transferal position. In relation to a transferal operation associated with a transition from a display region to a different display region, the transferal position may relate to a position on the different display region to which the transferal applies. For example, the transfer position may relate to a position that corresponds with the position of an information item of the display region, a position that is based, at least in part, on a calculation performed in relation to the position of the information item on the display region, a predetermined position, and/or the like. For example, the predetermined position may be a position in conformance with a position convention of the different display region. In such an example, the mere fact that the selected item is at a position of the display region causes determination of the transfer position on the different display region. For example, an interface item at a position that is not on the display region may preclude the apparatus from determination of a transfer position on the different display. In this manner, determination of the predetermined transfer position is based, at least in part on the position on the display region, for at least the reason that the position is on the display region, instead of another display region, or the different display region. In at least one example embodiment, the transfer position is determined based, at least in part, on the display region transferal folding input. For example, the apparatus may identify various types of display region transferal folding inputs, and may base the determination of the transfer position, at least in part, on the identified type of display region transferal folding input. The type of display region transferal folding input may be similar as described regarding FIGURES 4A-4D, FIGURES 5A-5C, and/or the like. In at least one example embodiment, the transferal operation may be based, at least in part on receipt of information indicative of a display region transferal unfolding input subsequent to the display region transferal folding input. For example, the apparatus may avoid performance of the transferal operation until the apparatus receives the information indicative of the display region transferal unfolding input. In this manner, the transferal operation may be caused, at least in part, by receipt of the information indicative of the display region transferal unfolding input subsequent to the display region transferal folding input.

[00100] In at least one example embodiment, a transferal operation relates to causation of transferal of the interface item from a display region to a different display region. For example the apparatus may cause transferal of the interface item from a position on the display region to a transfer position of the different display region. In at least one example embodiment, such a transition may comprise termination of display of the interface item from the first display region, and causation of display of the interface item on the second display region. In at least one example embodiment, such a transition may comprise continuation of display of the interface item from the first display region, and causation of display of the interface item on the second display region.

[00101] The examples of FIGURES 3A-3B illustrate transfer of a plurality of interface items from display region 301 to display region 302. The example of FIGURE 3A relates to a representation of interface items associated with circumstances prior to a transferal operation and the example of FIGURE 3B relates to a representation of interface items subsequent to the transferal operation, in accordance with at least one example embodiment. It can be seen, in FIGURE 3 A, that interface items 310, 311, and 312 relate to selected interface items, and that interface items 313, 314, 315, 316, and 317 relate to non-selected interface items. In at least one example embodiment, the apparatus may perform a transferal operation that causes transferal of selected interface items 310, 311, and 312 from display region 301 to display region 302. It can be seen, in FIGURE 3B, that display of interface items 310, 311, and 312 have been terminated from display on display region 301, and that interface items 310, 311, and 312 have been caused to be displayed on display region 302. Even though the example of FIGURE 3B illustrates interface items 310, 311, and 312 as retaining the size and configuration as in the example of FIGURE 3A, in some circumstances, the apparatus may change size and/or configuration of interface items 310, 311, and 312. For example, the apparatus may change size and/or configuration of interface items 310, 311, and 312 to conform to size and/or configuration of interface items 313, 314, and 315. Even though the examples of FIGURES 3A-3B illustrate transfer from display region 301 to display region 302, other examples may allow for transfer from display region 302 to display region 301. In such an example, selection of an interface item that is displayed on display region 302 may allow a display region transfer folding input to cause transfer from display region 302 to display region 301.

[00102] In some circumstances, it may be desirable for the transfer operation to relate to establishment of an association between an object of an interface item and an object of a different interface item. For example, the apparatus may determine that an object represented by a selected interface item is a transfer object. In such an example, the apparatus may identify a recipient object to which the apparatus will associate the transfer object. The apparatus may identify the recipient object based, at least in part, on the transfer position of the recipient object interface item. For example, for a transfer operation associated with a first display region and a second display region, the apparatus may identify the recipient object to be an object that correlates with the transfer position on the second display region. In this manner, the apparatus may cause establishment of an association between a transfer object identified by the interface element and recipient object.

[00103] In at least one example embodiment, establishment of an association between objects may relate to alteration of a data structure that introduces a reference to another data structure. For example, the association may relate to a connection in a database, addition of metadata, inclusion in a list, and/or the like. In at least one example embodiment, establishment of the association relates to storage of information indicative of the association in memory. For example, the apparatus may store, in memory comprised by the apparatus, information indicative of the association. In at least one example embodiment, establishment of the association relates to sending a directive to a separate apparatus, such that the directive identifies the association. For example, the apparatus may send a directive to a separate apparatus such that the different apparatus stores information indicative of the association. In such an example, the separate apparatus may be a server, a repository, and/or the like, that comprises data associated with the transfer object and/or the recipient object.

[00104] There may be many different types of associations that the apparatus may establish between a transfer object and a recipient object. For example, the recipient object may relate to a collection of a particular type of objects and the transfer object may relate to an object of the particular type. In such an example, the transfer operation may cause establishment of an association between the collection and the transfer object such that the transfer object is considered to be a part of the collection. For example, establishment of the association may comprise establishment of an association between the objects comprised by the collection of the recipient object and the transfer object. In at least one example embodiment, the recipient object may relate to a playlist, and the transfer object relates to a media object. The media object may relate to an audio object, a video object, an image object, and/or the like. In at least one example embodiment, the recipient object relates to a folder, and the transfer object relates to a program, a file, and/or the like. In at least one example embodiment, the recipient object relates to a contact list, and the transfer object relates to a contact object. A contact list may relate to a distribution list, a contact group, a blacklist, a whitelist, and/or the like. A contact object may relate to a phone number, messaging address, an identity, a uniform resource locator, and/or the like.

[00105] The examples of FIGURES 3C-3D illustrate transfer of a plurality of interface items from display region 351 to display region 352. The example of FIGURE 3C relates to a representation of interface items associated with circumstances prior to a transferal operation and the example of FIGURE 3D relates to a representation of interface items subsequent to the transferal operation, in accordance with at least one example embodiment. It can be seen, in FIGURE 3C, that interface items 360A, 361 A, and 362A relate to selected interface items, and that interface items 366, 367, and 368 relate to non- selected interface items. In can be seen in the example of FIGURE 3C that interface item 353 relates to a collection of objects that includes objects identified by representations 363, 364, and 365. For example, interface item 353 may relate to a playlist, and representations 363, 364, and 365 may represent albums, songs, other playlists, and/or the like. In at least one example embodiment, the apparatus may perform a transferal operation that causes establishment of associations between the objects of selected interface items 360A, 361 A, and 362A and the object of interface item 353. It can be seen, in FIGURE 3D, that objects of interface items 360A, 361 A, and 362A are respectively represented by representations 360B, 361B, and 362B. It can be seen that representations 360B, 361B, and 362B are included in interface item 353. In at least one example embodiment, such inclusion is indicative of the establishment of the association between the objects of 360A, 361 A, and 362 A and the object of interface item 353. For example, interface item 353 may relate to a playlist, and representations 360B, 361B, and 362B may represent albums, songs, other playlists, and/or the like. In this manner the albums, songs, other playlists, and/or the like, represented by representations 360B, 361B, and 362B, may have become associated with the playlist of interface item 353. It can be seen in the example of FIGURE 4D that the apparatus has changed size and/or configuration of interface items 360A, 361 A, and 362A to the size and configuration of representations 360B, 361B, and 362B to conform with size and/or configuration of representations 363, 364, and 365. Even though the examples of FIGURES 3C-3D illustrate transfer from display region 351 to display region 352, other examples may allow for transfer from display region 352 to display region 351. In such an example, selection of a representation that is displayed on display region 352 may allow a display region transfer folding input to cause transfer from display region 352 to display region 351.

[00106] FIGURES 4A-4D are diagrams illustrating a transposition position according to at least one example embodiment. The examples of FIGURES 4A-4D are merely examples and do not limit the scope of the claims. For example, number of interface items may vary, orientation of displays may vary, distance between displays may vary, and/or the like.

[00107] As previously described, in some circumstances, it may be desirable to identify different types of display region transferal folding inputs. In at least one example embodiment, an apparatus identifies a display region transferal folding input as a display region transposition transferal folding input. In at least one example embodiment, a display region transposition transferal folding input relates to an input that is indicative of the angle between a plurality of displays approaching an angle indicative of a closed position, a rapidly changing angle that may be indicative of the displays approaching a closed position, and/or the like. For example, a change from angle 230 of FIGURE 2C to angle 250 of FIGURE 2E may be indicative of a display region transposition transferal folding input.

[00108] The apparatus may base determination of the transfer position of an interface item displayed on a first display region, at least in part, on determination that a display region transferal folding input is a display region transposition transferal folding input. In at least one example embodiment, the apparatus determines the transfer position based, at least in part, on a transposition position. The apparatus may determine the transposition position based, at least in part, on the position of the selected interface item on the first display region. The transposition position may relate to a position that corresponds with transposition of the position of the interface item on the first display region onto a second display region.

[00109] In some circumstances, it may be desirable to determine the transfer position to be a transposition position to allow the transfer position to indicate a position that corresponds with the interface item in relation to the second display region when the displays are in a closed position. Such a transfer position may provide an impression to the user that the closing of the angle between the first display region and the second display region has caused the interface item to leap from a position of the first display region to a position on the second display region that is physically in front of the interface item.

[00110] In this manner, it may be desirable for the display region transposition transferal folding input to be indicative of displays approaching a closed position, of the displays reaching a closed position, and/or the like. For example, if the apparatus determines a change from a first angle between the displays to a second angle between the displays, the apparatus may determine the change in angle to be indicative of the display region transposition transferal folding input based, at least in part, on the second angle. For example, the apparatus may determine whether the second angle satisfies a

transposition transferal angle threshold. In at least one example embodiment, an angle satisfies a transposition transferal angle threshold if the angle is less than the transposition transferal angle threshold, if the angle is substantially equal to the transposition transferal angle threshold, and/or the like. In at least one example embodiment, substantially equal relates to a determination of equal within an error range that may be attributable to manufacturing tolerances, sensor tolerances, and/or the like. In at least one example embodiment, the transposition transferal angle threshold relates to a predetermined angle that designates an angle indicative of a closed position. For example, the transposition transferal angle threshold may relate to an angle that corresponds with the apparatus being in a closed position, to an angle that corresponds with the first display region facing the second display region, to an angle that corresponds with the first display region being substantially parallel with the second display region, and/or the like.

[00111] In at least one example embodiment, the apparatus determines that a display region transferal folding input relates to a display region transposition transferal folding input based, at least in part, on the angular velocity of the change from the first angle to the second angle. For example the apparatus may determine that a low angular velocity is inconsistent with a display region transposition transferal folding input, may determine that a high angular velocity is indicative of a display region transposition transferal folding input, and/or the like. In at least one example embodiment, the apparatus determines whether the change from the first angle to the second angle satisfies a transposition transferal angular velocity threshold. In at least one example embodiment, the transposition transferal angular velocity threshold relates to a predetermined angular velocity that designates a minimum angular velocity for identification of the display region transposition transferal folding input.

[00112] In at least one example embodiment, an angular velocity satisfies a transposition transferal angular velocity threshold if the angular velocity is less than the transposition transferal angular velocity threshold, if the angle is substantially equal to the transposition transferal angular velocity threshold, and/or the like.

[00113] FIGURE 4A is a diagram illustrating a transposition position according to at least one example embodiment. The example of FIGURE 4A illustrates selected interface elements 41 OA, 411 A, and 412A in relation to non-selected interface elements 413, 414, 415, and 416. The example of FIGURE 4A illustrates transferal position 410B, which indicates a transferal position of interface item 41 OA, transferal position 41 IB, which indicates a transferal position of interface item 411 A, and transferal position 412B, which indicates a transferal position of interface item 412A. It can be seen that the transferal position relate to a transposition onto display region 402 of the position of the respective interface item on display region 401. For example, if the displays are in a closed position such that the top of display region 401 is proximate to the bottom of display region 402, it can be seen that the transferal positions relate to positions on display region 402 that are physically in front of the respective interface items of display region 401 in such a closed position.

[00114] FIGURE 4B is a diagram illustrating a transposition position according to at least one example embodiment. In at least one example embodiment, regarding a transfer operation associated with an interface item displayed on a first display region to a second display region, a transposition position relates to a position on the second display region that corresponds with an intersection of a normal from the position on the first display region when the apparatus is in a closed position. This relationship may be seen in the example of FIGURE 4B. It can be seen that normal 423 relates to an imaginary line that is normal to display region 421. It can be seen that normal 423 intersects display region 421 at position 424, and intersects display region 422 at position 425. In this manner, the apparatus may determine that an interface item displayed at position 424 on display region 421 has a transposition position of position 425.

[00115] In at least one example embodiment, the apparatus determines the transposition position based, at least in part, on an axis that represents a line between the displays. For example, a selected interface item may be at a position on a first display region and the apparatus may determine a transposition position on a second display region. Where the position on the first display region corresponds with a first distance from a fist display region axis and a second distance along the first display region axis, and the transposition position may relate to a position on the second display region that corresponds with the first distance from the second display region axis and the second distance along the second display region axis. The axis may relate to a line between the first display region and the second display region, such as a boundary between the first display region and the second display region, a line that represents a midpoint between the first display region and the second display region, a line that relates to a vertex of an angle between the first display region and the second display region, and/or the like.

[00116] FIGURE 4C is a diagram illustrating a transposition position according to at least one example embodiment. In the example of FIGURE 4C, transfer position 460B relates to a transposition position of interface item 460A. In the example of FIGURE 4C, display region 451 and display region 452 have a boundary that relates to the bottom of display region 451 and the top of display region 452. It can be seen that interface item 460A is positioned at distance 461 A from the left edge of display region 451, and distance 462 A from the boundary. It can be seen that transfer position 460B is at distance 46 IB from the left edge of display region 452, and distance 462B from the boundary. Distance 46 IB may be proportional or equal to distance 461 A, and distance 462B may be proportional or equal to distance 462A. In this manner, transfer position 460B may relate to a transposition of the position of interface item 460A about the boundary between display region 451 and display region 452.

[00117] FIGURE 4D is a diagram illustrating a transposition position according to at least one example embodiment. In some examples, there may not be a boundary between the displays. For example the displays may be separated from each other. In such an example, the transposition position may be based, at least in part, on an axis that corresponds with a vertex of the angle between the displays. For example, the vertex may correspond with a flexural attachment between the housings of the displays.

[00118] In the example of FIGURE 4D, transfer position 480B relates to a transposition position of interface item 480 A. In the example of FIGURE 4D, display region 471 and display region 472 are at an angle with respect to each other at a vertex that corresponds with line 473. It should be understood that line 473 may be an imaginary line for purposes of calculation, and that there may not necessarily be a physical embodiment of such a line. It can be seen that interface item 480A is positioned at distance 481 A from the left edge of display region 471, and distance 482A from line 473. It can be seen that interface item 480A is positioned at distance 483 A from the bottom of display region 471. In this manner, distance 483A may differ from distance 482A by an amount of separation between the bottom of display region 471 and line 473.

[00119] It can be seen that transfer position 480B is at distance 481B from the left edge of display region 472, and distance 482B from line 473. It can be seen that transfer position 480B is positioned at distance 483B from the top of display region 472. In this manner, distance 483B may differ from distance 482B by an amount of separation between the top of display region 472 and line 473. Distance 48 IB may be proportional or equal to distance 481 A, and distance 482B may be proportional or equal to distance 482A. In this manner, transfer position 480B may relate to a transposition of the position of interface item 480A about line 473. In circumstances where the separation between display region 471 and line 473 differs from the separation between display region 472 and line 473, distance 483 A may fail to be proportional or equal to distance 483B. However, an apparatus may determine distance 438B based, at least in part, on distance 483 A and information indicative of the separation between display region 47 land line 473 and the separation between display region 472 and line 473.

[00120] In this manner, the transposition position may be a simple and intuitive result of a display region transposition transferal folding input by way of a user's likely familiarity with wet ink on a page of a book being transferred to an opposing page of the book when the book is closed. Such parallelism with a physical experience of the user may make such an input a simple and intuitive input for performing a transposition transfer operation.

[00121] FIGURES 5A-5C are diagrams illustrating position display region flow transferal according to at least one example embodiment. The examples of FIGURES 5A- 5C are merely examples and do not limit the scope of the claims. For example, number of interface items may vary, orientation of displays may vary, distance between displays may vary, and/or the like.

[00122] As previously described, in some circumstances, it may be desirable to identify different types of display region transferal folding inputs. In at least one example embodiment, an apparatus identifies a display region transferal folding input as a display region flow transferal folding input. The apparatus may perform a display region flow transferal based, at least in part, on the display region flow transferal folding input. In at least one example embodiment, a display region flow transferal relates to the apparatus causing display of an animation that illustrates movement of one or more selected interface items towards a transfer position. For example, the animation may simulate gravity pulling the interface item towards the transfer position. In this manner, the animation may provide the appearance of the interface item flowing from a position on a first display region to a transfer position on a second display region. In this manner, the user may be able to associate the folding action with the transferal of the interface item by identifying the transferal with a familiar gravitation effect. For example, the user may be familiar with tilting a wet surface and having the liquid flow across the surface in the direction of the tilt. In this manner, the user may find the change of angle associated with the display region flow transferal input to be a simple and intuitive input for transferring the interface item.

[00123] The display region flow transferal may be different from the display region transposition transferal. For example, the apparatus may determine a transfer position associated with an interface item at a position on a first display region to correspond with the first position. For example, the apparatus may avoid transposition of the position of the interface item with respect to a display region flow transferal. In at least one example embodiment, correspondence between the first position and the transfer position relates to the transfer position corresponding with a distance from a center of the first display region to the position on the first display region, the transfer position corresponding with a distance from a top of the first display region to the position on the first display region, the transfer position corresponding with a distance from a bottom of the first display region to the position on the first display region, the transfer position corresponding with a distance from a side of the first display region to the position on the first display region, and/or the like. In at least one example embodiment, the apparatus may determine correspondence between the position on the first display region with the transfer position to relate to such distances being equal, being proportional, being normalized to compensate for display region proportion differences, and/or the like.

[00124] In at least one example embodiment, upon receipt of a display region transferal folding input, the apparatus may distinguish a display region flow transferal folding input from a display region transposition transferal folding input based, at least in part, on the angular velocity of the display region transferal folding input. For example, the apparatus may determine that a display region transferal folding input that fails to satisfy a display region transposition transferal angular velocity threshold relates to a display region flow transferal folding input. In this manner, a display region flow transferal folding input may relate to a display region flow transferal input that has less angular velocity than a display region transposition transferal folding input.

[00125] FIGURE 5A is a diagram illustrating position associated with display region flow transferal according to at least one example embodiment. The example of FIGURE 5 A illustrates selected interface items 51 OA and 511A, and the respective transfer positions 510B and 51 IB, in relation to non-selected interface items 512 and 513. It can be seen that interface item 51 OA is at distance 515A from the left side of display region 501, and at a distance 516A from the bottom of display region 501, and that transfer position 510B is at distance 515B from the left side of display region 502, and at a distance 516B from the bottom of display region 502. In at least one example embodiment, distance 515B corresponds with distance 515 A, and distance 516B corresponds with distance 516A. In this manner, transfer position 510B may correspond with the position of interface item 510A on display region 501. It can be seen that interface item 511A is at distance 517A from the left side of display region 501, and at a distance 518A from the bottom of display region 501, and that transfer position 51 IB is at distance 517B from the left side of display region 502, and at a distance 518B from the bottom of display region 502. In at least one example embodiment, distance 517B corresponds with distance 517A, and distance 518B corresponds with distance 518 A. In this manner, transfer position 51 IB may correspond with the position of interface item 511 A on display region 501.

[00126] In at least one example embodiment, the apparatus causes display of an animation illustrating movement of the interface item from the position on the first display region towards the transfer position on the second display region. The animation may be indicative of the interface item flowing from its position prior to the animation to the transfer position. Such animation may relate to an animation that indicates the interface item moving from a display region to a different display region to reach the transfer position.

[00127] FIGURES 5B and 5C are diagrams illustrating parts of an animation associated with display region flow transferal according to at least one example

embodiment. In at least one example embodiment, the apparatus terminates display of the selected interface item upon display of the animation. However, in at least one example embodiment, the apparatus retains display of the selected interface item upon display of the animation. The example animation of FIGURES 5B and 5C relate to termination of display of the selected interface items upon display of the animation.

[00128] In the examples animation of FIGURES 5B and 5C, representations 5 IOC and 511C relate to representations of interface items 510A and 511 A, respectively. It can be seen in FIGURE 5B that the animation illustrates that representations 5 IOC and 511C have moved from their initial position towards their respective transfer positions. It can be seen in FIGURE 5C that the animation illustrates that representations 5 IOC and 511C have moved from their position in the example of FIGURE 5B towards their respective transfer positions. It can also be seen that the animation involves indication of representations 5 IOC and 511C crossing from display region 501 to display region 502. In this manner, the animation may aid in the user understanding the display region transition associated with the transferal operation.

[00129] As previously described, the display region flow transferal folding input may relate to a change from a first angle between displays to a second angle between displays. In at least one example embodiment, speed of the movement of the interface item, in the animation, is proportional to the second angle. For example, the speed of the movement of the interface item may be based, at least in part, on a difference between the second angle and ninety degrees. In such an example, the speed may be inversely proportional to the difference between the second angle and ninety degrees. In this manner, an angle that is closer to ninety degrees is associated with a quicker speed than an angle that is further from ninety degrees. It may be desirable to correlate speed of movement in this manner to allow the speed to correlate with the tilting of the display region. Such correlation may strengthen the similarity between the physical property of fluid moving across a surface and the display region flow transferal, and allow the user to better understand and remember the inputs and the effects of the input.

[00158] In some circumstances, a user may desire to terminate a display region flow transferal prior to completion of the display region flow transferal. For example, the user may have inadvertently provided the display region flow transferal folding input.

If the apparatus determines that the change from the first angle between the first display region and the second display region to the third angle between the first display region and the second display region relates to another display region flow transferal folding input, flow proceeds to block 1218. If the apparatus determines that the change from the first angle between the first display region and the second display region to the third angle between the first display region and the second display region fails to relate to another display region flow transferal folding input, flow proceeds to block 1220.

[00165] At block 1218, the apparatus continues display of the animation. In at least one example embodiment, the apparatus may proceed with performance of the transferal operation.
