Description

TECHNICAL FIELD

The present disclosure relates to the field of Social Network Service (SNS), and particularly, to a method and apparatus for providing a social network service, which can visualize and express user's emotions or opinions and can randomly arrange or permanently delete the content of conversation exchanged between the user and a counterpart.

BACKGROUND

Social Network Service (SNS) means an online platform which forms and strengthens social relations through free communication, information sharing, expansion of human network and the like among users. Most of SNSs are web-based services and provide a means for making contact with each other among the users through an e-mail or an instant messenger service.

An SNS application may provide services such as transfer of pictures, moving images and positions of the users and the like, and a user of the SNS application may communicate an intention to a counterpart using text. In addition, the user of the SNS application may confirm in real-time whether or not the counterpart has read a message, synchronize counterparts registered in a phone book of a cellular phone with a chatting counterpart list of the SNS application, and replace a background screen of a chat window with photos or pictures. Further, the user of the SNS application may communicate an emotion of the user to the counterpart in a chat room by inputting emoticons instead of text.

A procedure of providing an SNS service using the SNS application is as follows. The SNS application provides the user with the chatting counterpart list. If the user selects a counterpart that the user desires to chat with from the chatting counterpart list, a chat room screen is displayed. The user may additionally invite another chatting counterpart on the chat room screen; and if another chatting counterpart is not added, the user may perform one-to-one chatting with the initially selected counterpart, and if another chatting counterpart is added, the user may perform group chatting. The user inputs text or emoticons on the chat room screen to communicate text or emoticons to the counterpart.

Recently, leakage of personal information is emerging as an issue, wherein since a conventional SNS application records all of transmitted and received contents of a conversation from beginning to end, a serious infringement of privacy may occur if the contents of conversation are leaked. Furthermore, since the conventional SNS application communicates an intention by using text or emoticons, there is a problem in that an emotion of the user may not be expressed specifically. That is, since an emotion of the user is expressed using only limited emoticons or extremely limited buttons, an accurate and detailed emotion of the user may not be expressed. Since the expression of an emotion is an input of emoticons or text containing an intention of the user, there is a problem in that a content different from actual emotional and biological conditions may be selected so that an inaccurate emotion may be delivered to the counterpart. Further, since an emotion of the user is expressed using pre-formed emoticons and words, only a simple intention of the user is delivered.

FIG. 18 is a view showing a procedure of performing a message recall function in an SNS chat room, according to an embodiment of the present disclosure.

As shown in FIG. 18, when the SNS application is driven in the user equipment 130-1, the chatting counterpart list can be confirmed, and the SNS chat room can be created by selecting a desired chatting counterpart (step S1801). In another embodiment, the SNS chat room may be created using a method of creating an SNS chat room based on the position of the user equipment 130-1 described with reference to FIGS. 4 to 8. The user may transmit a message to a counterpart user equipment 130-n at the user equipment 130-1 (step S1802) and may select a specific message after transmitting the message and then select a message recall function (step S1803). When a message recall request is received from the specific user equipment 130-1, the SNS server 110 may delete the corresponding message from the counterpart user equipment 130-n and the SNS server 110 (step S1804).

An emotional signature (eMo) technique according to an embodiment of the present disclosure allows the SNS server 110 to digitize various emotional conditions of an SNS user and to transfer them to a counterpart user. In order to digitize various emotional conditions of the user, the user equipment 130-1 can be used to analyze the body temperature, blood flow, heartbeat, moisture of the skin, loudness of a voice, trembling of a voice, typing pattern, image pattern, video pattern and the like of the user. Further, in order to digitize an emotional condition of a user, it is possible to use at least one active method of directly inputting an emotional condition by the user using the user equipment 130-1 and one passive method of sensing an emotional condition of the user by the user equipment 130-1. In one embodiment, as one of the passive methods, a heartbeat rate per minute of the user can be measured using a heartbeat rate measurement sensor attached to the user equipment 130-1. A heartbeat rate of the user between forty and sixty may show a stable state (e.g., an emotional condition of comfort, pleasure or the like), a heartbeat rate between sixty and seventy may show a slightly excited state (e.g., an emotional condition of love, enjoyment or the like) and a heartbeat rate between seventy and one hundred may show an extremely excited state (e.g., an emotional condition of anger or the like). In another embodiment, as one of the passive methods, an emotional condition of the user can be digitized according to how many times a specific word has been used while the user exchanges messages with a counterpart. For example, if the word “love” has been used a predetermined number of times (e.g., five to ten times) while transmitting and receiving messages, an emotional condition of love can be expressed through a big data analysis. In another embodiment, as one of the passive methods, if a face included in an image is recognized as smiling, an emotional condition of pleasure may be expressed, or if the face is recognized as frowning, an emotional condition of anger may be expressed. In another embodiment, if a voice input by the user through the user equipment 130-1 is not greater than a predetermined level (e.g., 10 to 15 dB), a stable emotional condition may be expressed, and if the voice is not less than a predetermined level (e.g., 25 to 35 dB), an excited (angered) emotional condition (anger) may be expressed.

In one embodiment, the SNS server 110 may express an emotional condition in a circular shape (see “C” of FIG. 19) or the like blinking at an end of an SNS message, an image, a moving image, text or the like by using digitized emotional condition data (e.g., love, pleasure, anger or the like) of the user. The emotional condition may be expressed in a triangular or square shape instead of the circular shape. In addition, the expressed emotional condition may reflect the emotional condition of the user changing in real-time.

The SNS providing environment 100, i.e., the SNS server 110 and the user equipments 130-1 to 130-n, may share the digitized emotional condition of the user. That is, a specific user equipment 130-1 may measure an emotional condition of a user, transmit a corresponding measurement value of the emotional condition of the user to the SNS server 110 to be stored therein, and transmit the digitized emotional condition of the user to other user equipments 130-n connected through the network 120. The SNS server 110 may perform various signal processing such as analysis, statistics and the like using the digitized emotional condition data of the user received from the user equipments 130-1 to 130-n.

In addition, a specific user equipment 130-1 may transmit a measurement value of an emotional condition of a user to other user equipments 130-n connected using the network 120 without passing through the SNS server 110. In one embodiment, the user equipments 130-1 to 130-n may include various smart devices such as a personal computer, a tablet, a smart phone, a notebook computer, a personal digital assistant (PDA) and the like. In one embodiment, the SNS server 110 may store the digitized emotional condition of a user together with and incorporated into data of an SNS message, an image, a moving image, text or the like or separately from an SNS message data, an image, a moving image, text or the like.

FIGS. 19 to 26 are views showing an emotional signature displayed on a variety of media, according to an embodiment of the present disclosure. FIG. 19 shows an emotional signature displayed in a circular shape C on the user equipment 130-1 such as a smart phone or the like. Such an emotional signature may be used to express an emotion by the user himself/herself even during general use of the user equipment 130-1 (e.g., calling, web surfing or the like), may be transmitted together upon transmission of a message in the SNS chat room as shown in FIG. 10, and may be transmitted together with a moving image even upon transmission of the moving image as shown in FIG. 11, but it is not limited thereto. FIG. 20 shows an emotional signature expressed in a circular shape C on a smart television set ST, FIG. 21 shows an emotional signature expressed in a circular shape C on an electronic book EB, FIG. 22 shows an emotional signature expressed in a circular shape C on an electronic newspaper EN, FIG. 23 shows an emotional signature expressed in a circular shape C on an electronic magazine E-M, FIG. 24 shows an emotional signature expressed in a circular shape C on an electronic picture frame EF, and FIG. 25 shows an emotional signature expressed in a circular shape C on a web page of a personal computer PC.

FIG. 26 is a view showing responsive colors for expression emotional signatures of a user, according to an embodiment of the present disclosure.

As shown in FIG. 26, the SNS server 110 may store the emotional condition of the user by mapping boredom to gray, disgust to purple, surprise to blue, pleasure to sky-blue, stability to green, comfort to yellowish green, enjoyment to yellow, expectation to orange, love to pink and anger to red. Further, when the SNS server 110 receives the digitized emotional signature of the user, it may display a color mapped to the corresponding emotional signature at an end of an SNS message, an image, a moving image, text or the like, for example, in a circular shape (see “C” of FIG. 25).
