The above and other aspects, features and advantages of the present disclosure will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which:
Hereinafter, various embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that there is no limiting the present disclosure to the particular forms disclosed herein; rather, the present disclosure should be construed to cover various modifications, equivalents, and/or alternatives of embodiments of the present disclosure. In describing the drawings, similar reference numerals may be used to designate similar constituent elements.
As used herein, the expressions “have”, “may have”, “include”, or “may include” refer to the existence of a corresponding feature (e.g., numeral, function, operation, or constituent element such as component), and do not exclude one or more additional features.
In the present disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include all possible combinations of the items listed. For example, the expressions “A or B”, “at least one of A and B”, or “at least one of A or B” refer to all of (1) including at least one A, (2) including at least one B, or (3) including all of at least one A and at least one B.
The expressions such as “first”, “second”, and the like as used in various embodiments of the present disclosure may modify various elements regardless of order or importance, and do not limit corresponding elements. The above-described expressions may be used to distinguish an element from another element. For example, a first user device and a second user device indicate different user devices although both of them are user devices.

The bus 110 is a circuit that interconnects the aforementioned elements and transmits communication signals (e.g., control messages) between the aforementioned elements.
The processor 120 carries out operations or data processing related to control and/or communication of at least one other component (for example, the memory 130, the input/output interface 150, the display 160, or the communication interface 170) of the electronic device 101.
The memory 130 stores commands or data (e.g., a reference pattern or a reference touch area) associated with one or more other components of the electronic device 101. According to an embodiment of the present disclosure, the memory 130 stores software and/or a program 140. For example, the program 140 includes a kernel 141, a middleware 143, an application programming interface (API) 145, an application program or application 147, and the like, with one or more of the kernel 141, the middleware 143, and the API 145 being referred to as an operating system (OS).
The kernel 141 controls or manages system resources (e.g., the bus 110, the processor 120, or the memory 130) used for performing an operation or function implemented by the other programs (e.g., the middleware 143, the API 145, or the application 147). Furthermore, the kernel 141 provides an interface through which the middleware 143, the API 145, or the application 147 may access the individual elements of the electronic device 101 to control or manage the system resources.
The middleware 143, for example, functions as an intermediary for allowing the API 145 or the application 147 to communicate with the kernel 141 to exchange data. In addition, the middleware 143 processes one or more task requests received from the application 147 according to priorities thereof. For example, the middleware 143 assigns priorities for using the system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) of the electronic device 101, to at least one application of the application 147. For example, the middleware 143 performs scheduling or loading balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned thereto.
The API 145 is an interface through which the application 147 controls functions provided from the kernel 141 or the middleware 143, and may include, for example, at least one interface or function (e.g., instruction) for file control, window control, image processing, or text control.
The input/output interface 150 forwards instructions or data input from a user through an input/output device (e.g., various sensors, such as an acceleration sensor or a gyro sensor, and/or a device such as a keyboard or a touch screen), to the processor 120, the memory 130, or the communication interface 170 through the bus 110. For example, the input/output interface 150 provides the processor 120 with data on a user's touch entered on a touch screen. Furthermore, the input/output interface 150 outputs instructions or data, received from, for example, the processor 120, the memory 130, or the communication interface 170 via the bus 110, through an output unit (e.g., a speaker or the display 160).

According to an embodiment of the present disclosure, the server 106 may include a group of one or more servers. All or a part of operations performed in the electronic device 101 may be performed in the other electronic device or the first external electronic device 102 or the second external electronic device 104 or the server 106. When the electronic device 101 should perform some functions or services automatically or by a request, the electronic device 101 may make a request for performing at least some functions related to the functions or services by the first external electronic device 102, the second external electronic device 104, or the server 106 instead of performing the functions or services by itself. The first external electronic device 102, the second external electronic device 104, or the server 106 may perform a function requested from the electronic device 101 or an additional function and transfer the performed result to the electronic device 101. The electronic device 101 may provide the requested function or service to another electronic device by processing the received result as it is or additionally.
