[0112] When the second user (50-2) performs the action of tapping the second user terminal device (200-2) on the electronic device (100) while the login for the first account is maintained, the electronic device (100) detects the user interaction and obtains login information from the user terminal device (200-2), and can perform a login to the second account using the obtained login information.

[0113] When the electronic device (100) performs a login to the second account while the login to the first account is maintained, it can execute a multi-login function and display a UI (166-2) indicating that the first account and the second account are linked to the electronic device (100).

[0114] On the other hand, if a login is performed with a second account and a log off is performed on the first account that was previously logged in, the login account may switch from the first account to the second account. This is explained in detail in FIG. 8.

[0115] FIG. 7 is a drawing for explaining the operation of performing a login to an electronic device according to at least one embodiment of the present disclosure.

[0116] Referring to FIG. 7, when the electronic device (100) detects at least one of a first user interaction or a second user interaction, it can obtain distance information of a user terminal device located within a preset radius of the electronic device (100) and identify a user terminal device to obtain login information based on the distance information.

[0117] For example, when a first user (50-1) taps an electronic device (100) using a first user terminal device (200-1), the electronic device (100) can identify the user terminal device within a preset radius.

[0118] When the electronic device (100) identifies a first user terminal device (200-1), a second user terminal device (200-2), and a third user terminal device (200-3) within a preset radius, it can obtain distance information for each user terminal device using at least one sensor. For example, the electronic device (100) can calculate the distance between the electronic device (100) and the user terminal device using an ultrasonic sensor.

[0119] The electronic device (100) can compare distance information of each user terminal device and, if it identifies the first user terminal device (200-1) as being located at the closest distance, identify the first user terminal device (200-1) as the user terminal device to obtain login information. That is, it can obtain user account information or login information by performing communication with the first user terminal device (200-1).

[0120] The electronic device (100) can obtain account information or login information of the first user (50-1) based on information obtained from the first user terminal device (200-1) and perform a login to the first user's account. In this case, the electronic device (100) can display a UI (167) indicating that a login to the first user's (50-1) account has been performed.

[0121] FIG. 8 is a drawing for explaining the operation of performing a login to an electronic device according to at least one embodiment of the present disclosure.

[0122] Referring to FIG. 8, the electronic device (100) can perform a log off for the first account and maintain a login state for the second account based on a preset condition. Here, “preset condition” may mean a condition to disable a multi-login function that performs simultaneous login with multiple accounts.

[0123] For example, when a first user (50-1) performs the action of tapping the first user terminal device (200-1) on the electronic device (100), the electronic device (100) detects the user interaction and obtains login information from the user terminal device (200-1), and can perform a login to the first account using the obtained login information.

[0124] When a login is performed with the first account, the electronic device (100) can display a UI (168-1) indicating that the user terminal device (200-1) is linked to the electronic device (100) through the first account.

[0125] When the second user (50-2) performs the action of tapping the second user terminal device (200-2) on the electronic device (100) while the login for the first account is maintained, the electronic device (100) detects the user interaction and obtains login information from the user terminal device (200-2), and can perform a login to the second account using the obtained login information.

[0126] In this case, if a condition to disable the multi-login function that performs simultaneous login with multiple accounts on the electronic device (100) is set, the multi-login is not executed and the previously logged-in account can be switched to the newly logged-in account.

[0127] For example, the electronic device (100) can display a UI (168-2) indicating that the device has switched from a first account that is already logged in to a second account that is newly logged in.

[0128] FIG. 9 is a drawing for explaining the operation of displaying an image on an electronic device according to at least one embodiment of the present disclosure.

[0129] The electronic device (100) can control a communication interface to receive an image from at least one of a first user terminal device or a second user terminal device, and control a display to display the received image.

[0130] For example, when a user taps an electronic device (100) using a user terminal device (200) in which a video (269) is being played, the electronic device (100) can receive data regarding the video (269) being played on the user terminal device and display the received video (169).

[0131] At this time, the operation of receiving and displaying video from a user terminal device connected via communication may be referred to as a “mirroring function,” but is not limited thereto, and may be referred to by various terms such as screen casting, screen duplication, display sharing, screen sharing, and screen transfer.

[0132] Meanwhile, it is not limited to this, and if the electronic device (100) is an electronic device including a speaker (e.g., an audio device), it may receive audio being played on a user terminal device and play the received audio.

[0133] As another example, if the electronic device (100) is a portable projector capable of performing a speaker function, it may receive a video being played on a user terminal device and display it in a projected form, and if audio is being played along with the video, it may receive the audio and play it through the speaker.

[0134] In addition, it is possible to connect to a network of electronic devices by receiving not only video or audio data from the user terminal device, but also connection information stored in the user terminal device.

[0135] For example, if the electronic device is a TV and is not connected to a network, tapping the user terminal device on the TV can receive mobile Wi-Fi information or hotspot information stored on the user terminal device, and the TV can be connected to the network using the received mobile Wi-Fi information or hotspot information.

[0136] FIG. 10 is a flowchart illustrating the operation of performing a login to an electronic device according to at least one embodiment of the present disclosure.

[0137] Referring to FIG. 10, when the electronic device detects a first user interaction, it can obtain login information from the first user terminal device and perform a login with the first account (S1010).

[0138] Here, “user interaction” includes interaction between a user and an electronic device. Interaction may include the act of a user inputting user input, such as touch, voice, or gestures, into an electronic device through a user interface to use the electronic device, or the user input itself. Additionally, interaction may include the response of the electronic device to the user input, and the response may consist of tactile, visual, auditory, and a combination of at least two of these.

[0139] For example, if user A says “Please log in with account A,” the electronic device may detect the user’s voice utterance as user interaction and perform a login with account A.

[0140] When the electronic device detects a second user interaction after a login to the first account has been performed, it can obtain login information from the second user terminal device and perform a login to the second account while maintaining the login to the first account (S1020).

[0141] Here, “second user interaction” may refer to a user interaction detected after the first user interaction has been detected. Additionally, the “action of logging in to a second account while the login to the first account is maintained” may be referred to as a “multi-login function.”

[0142] Here, the “multi-login function” may refer to a function that allows logging in with multiple accounts to a single electronic device or a single program, and managing the data of each account in an integrated manner.

[0143] FIG. 11 is a flowchart illustrating an operation for identifying a user terminal device according to at least one embodiment of the present disclosure.

[0144] When the electronic device detects at least one of the first user interaction or the second user interaction, it can obtain distance information of a user terminal device located within a preset radius of the electronic device (S1110).

[0145] The electronic device can identify a user terminal device located within a preset radius using a motion sensor and obtain distance information of the identified user terminal device using an ultrasonic sensor.

[0146] The electronic device can identify a user terminal device to acquire login information based on acquired distance information (S1120).

[0147] For example, if multiple user terminal devices are identified using a motion sensor, the user terminal device closest to the electronic device can be identified as the user terminal device to obtain login information based on the distance information of the identified user terminal devices. However, this is not limited to this, and the user terminal device to obtain login information can also be identified using data other than distance information based on various sensors.

[0148] The multi-login execution method described in FIGS. 10 and 11 may be performed by a device having various configurations such as FIGS. 2 and 3 described above, but is not necessarily limited thereto and may be performed by a device having various configurations.

[0149] The various embodiments described above may be implemented as individual embodiments, or at least one embodiment may be combined with one another, either wholly or partially, to be implemented together in a single device.

[0150] According to the various embodiments described above, by linking multiple accounts through the multi-login function, users can utilize content in an optimized state. Ultimately, the user experience can be improved.

[0151] Various embodiments of the present disclosure may be implemented as software stored on a machine-readable storage media that can be mounted on or connected to a smartphone, a user terminal device, and various other electronic devices (e.g., a computer).

[0152] Specifically, a non-transient readable storage medium may be provided that stores software for sequentially performing steps of: obtaining login information from a first user terminal device and performing a login with a first account when user interaction is detected; obtaining login information from a second user terminal device and performing a login with a second account when user interaction is detected after the login with the first account is performed; and executing a multi-login function corresponding to the login state when the login state is maintained based on the first account and the second account.

[0153] A device equipped with such a non-transient readable medium can perform various operations such as tag identification corresponding to user actions described in the various embodiments above, verification of importance per multiple frames, and generation of edited images.

[0154] In non-transitory readable storage media, 'non-transitory' simply means that the storage medium does not contain a signal and is tangible; it does not distinguish whether data is stored semi-permanently or temporarily on the storage medium.

[0155] Alternatively, a program for performing the methods according to the various embodiments described above may be distributed online through an application store. In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily created in a storage medium such as the memory of a manufacturer's server, an application store's server, or a relay server.

[0156] Each component (e.g., module or program) according to various embodiments may consist of a single or multiple entities, and some of the aforementioned sub-components may be omitted, or other sub-components may be further included in various embodiments. Generally or additionally, some components (e.g., module or program) may be integrated into a single entity to perform the same or similar functions as those performed by each of the respective components prior to integration.

[0157] Operations performed by a module, program, or other component according to various embodiments may be executed sequentially, in parallel, iteratively, or heuristically, or at least some operations may be executed in a different order, omitted, or other operations may be added.

[0158] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above. It is understood that various modifications can be made by those skilled in the art without departing from the essence of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present disclosure.
