Provided are methods and systems for providing a game based on a video call and object recognition. A game providing method of an electronic device configured as a computer including displaying game content on a video call screen in response to a video call being established between a user of the electronic device and a counterpart through a voice over Internet protocol (VoIP) channel, recognizing an object in a call image as motion data with respect to the game content, and controlling a game element corresponding to the game content using a result of the recognizing may be provided.

Method and system for providing game based on video call and object recognition

A video call providing method using a video call providing device capable may include: transmitting or receiving, by the video call providing device, a signal of displaying a first effect while the video call is performed to or from the external communication device; transmitting or receiving, by the video call providing device, a signal of displaying a second effect to or from the external communication device, after the first effect is transmitted or received; verifying, by the video call providing device, a type of the first effect, and a type of the second effect, after the second effect is transmitted or received; determining, by the video call providing device, an additional output of an effect and an additional effect to be output; and displaying, by the video call providing device, the additional effect, based on the determined additional output and additional effect.

Video call providing device, method, system, and non-transitory computer readable medium storing a computer program

Provided is a method, system, and non-transitory computer-readable recording medium for delivering audio feedback of a viewer to a caster during a live broadcast. A method implemented on a computer system includes providing a live broadcast by receiving broadcast content transmitted from an electronic device of a caster, and by streaming the received broadcast content to each of electronic devices of a plurality of users through a communication session established between an account of the caster and accounts of the plurality of users; receiving an audio feedback about the live broadcast from an electronic devices of a user during the live broadcast; and delivering the audio feedback to the electronic device of the caster.

Method, system, and non-transitory computer readable medium for audio feedback during live broadcast

Provided is a method, a system, an apparatus, and/or a non-transitory computer readable medium for providing a ringback tone and a ringtone using a Voice over Internet Protocol (VoIP) call service. A call method may provide sound sources directly edited by users as a ringtone or a ringback tone in a VoIP call service.

Method and system for providing ringback tone service and ringtone service in Voice over Internet Protocol (VoIP) call service

An apparatus for providing a document sharing service based on a messaging service. The apparatus includes a memory configured to store computer readable instructions and a processor configured to execute the computer readable instructions. The processor is configured to execute the computer readable instructions to receive a document transmission signal for transmitting a document displayed in a chat window of a first chat group from a first terminal application corresponding to a member of the first chat group, to a second chat group via second terminal applications respectively corresponding to members of the second chat group, the second chat group being different from the first chat group, obtain a document identifier from the document transmission signal, retrieve a document corresponding to the document identifier, transmit the document to the second terminal applications, and update shared status information of the document in the database based on a shared status of the document in the second chat group. The shared status information includes at least one of a number of users who read the document, and a number of chat groups to which the document is transmitted.

Apparatus for providing document sharing service based on messaging service, and method using the apparatus

A video call method and system may use a two-way transmission of a visual effect or an auditory effect. A server may manage and store content that includes visual information or auditory information as an effect to apply to a video call in association with an effect identifier. A server may receive, during the video call, an effect identifier and may transmit the visual information or audio information associated with the effect identifier to a reception-side electronic device together with a data packet for the video call.

Method and system for video call using two-way communication of visual or auditory effect

A method of providing a document sharing service based on a messaging service includes: receiving, by a server, a document transmission signal for transmitting a document which is displayed in a chat window of a first chat group from a first terminal application corresponding to a member of the first chat group, to second terminal applications respectively corresponding to members of a second chat group different from the first chat group; obtaining, by the server, a document identifier from the document transmission signal, searching, by the server, a database for a document corresponding to the document identifier, and transmitting, by the server, the document to the second terminal applications; and updating, by the server, shared status information of the document in the database based on a shared status of the document in the second chat group.
