A user interface (not shown) for ON/OFF of sound may be provided on the swipe-to-preview user interface. The user may listen to the sound of sticker contents using the user interface for ON/OFF of sound. 
       FIG.  8    illustrates an example of an operation of browsing sticker contents in response to a control instruction of a user according to at least one example embodiment. The control instruction may be input from the user to sticker contents displayed on the swipe-to-preview interface  430 . Control information of the user refers to mobile gesture information that includes a tap, a split tap, a flick, and a swipe and represents inputting an instruction using a finger on a touchscreen. For example, gestures of using five fingers starting from a single finger may be present. A tap gesture refers to tapping a touchscreen of an electronic device with a finger, a split tap gesture refers to tapping with one finger on the touchscreen first and then another finger, a flick gesture refers to softly flicking a finger left/right and up/down, and a swipe gesture refers to swiping the touchscreen longer than the flick. Here, the flick gesture on the swipe-to-preview interface also could be referred to as the swipe gesture. 
     The processor  220  may receive swipe information as the control instruction of the user. The processor  220  may move a location of sticker contents based on the received swipe information and may display corresponding sticker contents at the moved location. When the sticker contents corresponding to the moved location are positioned at the center of the swipe-to-preview interface  430 , the sticker contents may be highlighted to be larger and darker than when the sticker contents are positioned at sides of the swipe-to-preview interface  430 . For example, when three sticker contents are displayed on the swipe-to-preview interface  430 , the sticker content positioned at the center of the swipe-to-preview interface  430  may be displayed to be larger and darker and the sticker contents at both sides may be displayed to be relatively smaller and lighter. Also, a size of sticker content displayed on the swipe-to-preview interface  430  and a size of the swipe-to-preview interface  430  may be adjusted according to a type of sticker content positioned at the center of the swipe-to-preview interface  430 . When sticker content including an action is positioned at the center of the swipe-to-preview interface  430 , the size of the sticker content including the action may increase. According to an increase in the size of the sticker content including the action displayed on the swipe-to-preview interface  430 , the size of the swipe-to-preview interface  430  may also be expand. 
     An example in which swipe information is input in a left direction or a right direction is described. Here, without being limited to the left/right direction, the swipe information may be configured to be input in up (upper) and down (lower) directions. For example, swipe information may be input in the left direction or the right direction by a user  810 . In response to the swipe information being input in the left direction from the user  810 , sticker contents configured in the swipe-to-preview interface  430  may move in the left direction. In response to the swipe information being input in the right direction from the user  810 , the sticker contents configured in the swipe-to-preview interface  430  may move in the right direction. For example, it is assumed that (N−2)-th sticker content (e.g., heart), (N−1)-th sticker content (e.g., trapezoid), N-th sticker content (e.g., rounded rectangle), (N+1)-th sticker content (e.g., rhombus), and (N+2)-th sticker content (e.g., star) are configured in the swipe-to-preview interface  430 . For example, the (N−1)-th sticker content (e.g., trapezoid), the N-th sticker content (e.g., rounded rectangle), and the (N+1)-th sticker content (e.g., rhombus) may be displayed on the swipe-to-preview interface  430 . For clarity of description, an example in which one sticker content is moved according to swipe information of the user and displayed on the swipe-to-preview interface  430  is described. In response to the swipe information being input in the right direction to the swipe-to-preview interface  430  from the user  810 , the (N−2)-th sticker content (e.g., heart), the (N−1)-th sticker content (e.g., trapezoid), and the N-th sticker content (e.g., rounded rectangle) may be displayed on the swipe-to-preview interface  430 . In response to the swipe information being input in the left direction to the swipe-to-preview interface  430  by the user  810 , the N-th sticker content (e.g., rounded rectangle), the (N+1)-th sticker content (e.g., rhombus), and the (N+2)-th sticker content (e.g., star) may be displayed on the swipe-to-preview interface  430 . 
     For example, a moving speed of sticker contents displayed on the swipe-to-preview interface  430  may be determined according to strength of the swipe information input from the user  810 . That is, the swipe-to-preview interface  430  may be configured such that a browsing speed of sticker contents may be applied according to the strength of the swipe information input from the user  810 . For example, when swipe information is quickly or forcefully input in the left direction or the right direction from the user  810 , sticker contents displayed on the swipe-to-preview interface  430  may be quickly moved. In some example embodiments, when swipe information is slowly or weakly input in the left direction or the right direction from the user  810 , sticker contents displayed on the swipe-to-preview interface  430  may be slowly moved. 
     A control instruction may be input for sticker content desired by the user  810  among sticker contents that are configured to move on the swipe-to-preview interface  430 . Here, double tap information may be input as the control instruction of the user  810 . For example, in response to the double tap information being input as the control instruction of the user  810  at the center of the swipe-to-preview interface  430 , sticker content selected by the user may be transmitted to a chatroom of a message transmission and reception service. 
     Also, in response to double tap information being input as the control instruction of the user  810  around the center of the swipe-to-preview interface  430 , movement to the auto-suggestion area  410  including sticker contents configured in relation to a keyword input from the user  810  may be performed. That is, the swipe-to-preview interface  430  may be terminated. In some example embodiments, a user interface for terminating the swipe-to-preview interface  430  may be provided at a specific location of the swipe-to-preview interface  430 . For example, the user interface for terminating the swipe-to-preview interface  430  may be displayed at an upper right end of the swipe-to-preview interface  430 . In response to a selection on the user interface for terminating the swipe-to-preview interface  430  displayed at the upper right end of the swipe-to-preview interface  430  from the user  810 , the swipe-to-preview interface  430  may be terminated. 
       FIG.  9    illustrates an example of an operation of adjusting a size of a swipe-to-preview interface in a case that sticker content includes an action, according to at least one example embodiment. 
     The processor  220  may adjust the size of the swipe-to-preview interface  430  based on a type of sticker content corresponding to a location moved according to swipe information of a user. For example, the type of sticker content may include a sticker content, a sticker content including a text, and/or a sticker content including an action. 
     The processor  220  may set the size of the swipe-to-preview interface  430  to be maintained when the type of sticker content is the sticker content or the sticker content including the text and may set the size of swipe-to-preview interface  430  to expand by assigning an expansion effect to the swipe-to-preview interface  430  when the type of sticker content is the sticker content including the action. Here, the expansion effect represents that the size of the swipe-to-preview interface  430  is expanded. The user may recognize that the size of the swipe-to-preview interface  430  is being expanded. 
     When the type of sticker content is the sticker content including the action, the processor  220  may dynamically expand the swipe-to-preview interface  430  by size information set to correspond to a size of the sticker content including the action. For example, a process in which, in response to occurrence of the expansion effect, the swipe-to-preview interface  430  expands by a size set to correspond to a size of the sticker content including the action may be displayed. When sticker content corresponding to a location moved according to a control instruction of the user is the sticker content or the sticker content including the text rather than the sticker content including the action, the processor  220  may reduce the size of the expanded swipe-to-preview interface  430 . 
     The apparatuses described above may be implemented using hardware components, software components, and/or a combination thereof. For example, the apparatuses and components described herein may be implemented using one or more general-purpose or special purpose computers, for example, a processor, a controller, an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a programmable logic unit (PLU), a microprocessor, or any other device capable of responding to and executing instructions in a defined manner. The processing device may run an operating system (OS) and one or more software applications that run on the OS. The processing device also may access, store, manipulate, process, and create data in response to execution of the software. For simplicity, the description of a processing device is used as singular; however, one skilled in the art will be appreciated that the processing device may include multiple processing elements and/or multiple types of processing elements. For example, the processing device may include multiple processors or a processor and a controller. In addition, different processing configurations are possible, such as parallel processors. 
     The software may include a computer program, a piece of code, an instruction, or some combinations thereof, for independently or collectively instructing or configuring the processing device to operate as desired. Software and/or data may be embodied in any type of machine, component, physical equipment, virtual equipment, a computer storage medium or device, or in a propagated signal wave capable of providing instructions or data to or being interpreted by the processing device. The software also may be distributed over network coupled computer systems so that the software is stored and executed in a distributed fashion. The software and data may be stored by one or more computer readable storage mediums. 
     The methods according to some example embodiments may be configured in a form of program instructions performed through various computer methods and recorded in non-transitory computer-readable media. The media may include, alone or in combination with program instructions, data files, and data structures. The program instructions recorded in the media may be specially designed and configured for the example embodiments or may be known to and available to those skilled in the computer software art. Examples of the media include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical media such as CD-ROM and DVDs; magneto-optical media such as floptical disks; and hardware devices that are specially configured to store and perform program instructions, such as ROM, RAM, flash memory, and the like. Examples of program instructions include a machine language code as produced by a compiler and a high-level language code executable by a computer using an interpreter. 
     Any functional blocks shown in the figures and described above may be implemented in processing circuitry such as hardware including logic circuits; a hardware/software combination such as a processor executing software; or a combination thereof. For example, the processing circuitry more specifically may include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a System-on-Chip (SoC), a programmable logic unit, a microprocessor, application-specific integrated circuit (ASIC), etc. 
     The methods (as well as the computer devices) according to some example embodiments of the present disclosure provide a swipe-to-preview interface in response to a selection on one sticker contents configured in relation to a keyword input from a user, and enable the user to preview a subset of the sticker contents displayed on the swipe-to-preview interface and take an action within the preview screen, Thus, a dedicated user interface configured to allows a user to browse other sticker contents before transmitting a sticker content may be provided within a message, instead of automatically converting and delivering a sticker content corresponding to a specific keyword as in the conventional methods. Thus, there is no need for a user to perform additional operations to generate a preview screen including sticker contents, from which the user can select a sticker content different from the one initially recommended by the system, thereby consuming lesser computing resources and less power. 
     While this disclosure includes specific example embodiments, it will be apparent to one of ordinary skill in the art that various alterations and modifications in form and details may be made in these example embodiments without departing from the spirit and scope of the claims and their equivalents. For example, suitable results may be achieved if the described techniques are performed in a different order, and/or if components in a described system, architecture, device, or circuit are combined in a different manner, and/or replaced or supplemented by other components or their equivalents.
