The control unit 130 creates a name tag by identifying a name of a contact person from the log data analyzed at step S310 in step S320. The name tag may be a name of the contact person or a nickname stored in a telephone book of the mobile terminal 100. The control unit 130 then calculates group levels according to the human contact frequency in step S330. The group levels may be calculated by subtracting the lowest human contact frequency from the highest human contact frequency on the log data list, and dividing the difference by a predetermined number of group levels. The number of group levels may be set at a production process of the mobile terminal, or by a user in a display setting of a people cloud screen. For example, in a case where the highest human contact frequency is 20, the lowest human contact frequency is 2, and the predetermined number of group levels for displaying a name tag is 4, the difference between the human contact frequencies is 18 (20−2) and the range of a group level becomes 4.5 (18÷4), as shown in Table 4.









TABLE 4






Group level
Range (R) of group level








Group level 1
  2 ≦ R ≦ 6.5



Group level 2
 6.5 < R ≦ 11



Group level 3
  11 < R ≦ 15.5



Group level 4
15.5 < R ≦ 20









Alternatively, the group level may be set by the user without a calculating process. For example, the range of group level 1 may be set to ‘less than or equal to 10’, the range of group level 2 may be set to ‘more than 10 and less than or equal to 25’, and so on.
The control unit 130 classifies the name tags according to the calculated group levels in step S340. The control unit 130 identifies the total human contact frequency corresponding to the name tag and determines the group level of the name tag. For example, referring to Table 3, the total human contact frequency of Name 1 is 20, and the control unit 130 compares this value with each range of the group levels shown in Table 4 and determines the group level of Name 1 as ‘Group level 4’. When the classification of the name tag is complete, the process continues at step S230 of FIG. 2.
The control unit 130 displays a people cloud screen including a name tag in the display unit 140 in step S230.
FIG. 4 is a flow chart showing a detailed process of step S230 of displaying a people cloud screen in the method of displaying human contact data of FIG. 2. FIGS. 5A to 5C are views of display screens showing a people cloud screen displayed in the method of displaying human contact data of FIG. 2. FIGS. 6A to 6C are views of display screens showing steps of identifying detailed information by selecting a name tag in the method of displaying human contact data of FIG. 2.
Referring to FIG. 4, the control unit 130 controls the display unit 140 to display name tags in step S410, as shown in FIGS. 5A to 5C. The order of displaying name tags may be set by the user, as shown in the display screens of FIGS. 5A to 5C. According to the user setting, the name tags may be displayed in alphabetical order as shown in FIG. 5A, in order of human contact frequency as shown in FIG. 5B, or in order of event generation time point as shown in FIG. 5C. The order of displaying name tags is determined by selecting a display method from a menu or by inputting a specific key.
The control unit 130 then identifies whether a name tag is selected from the displayed name tags in step S415. If a name tag is selected from the displayed name tags, the control unit 130 identifies whether an executable function is assigned to the selected name tag. The executable function may be a function of displaying a log data list of the selected name tag or of executing a human contact event corresponding to the selected name tag. The control unit 130 determines which one of the executable functions is selected by the user in step S420.
If the function of executing a human contact event is selected, the control unit 130 controls the display unit 140 to display the types of human contact events in a pop-up window in step S421. The type of human contact events displayed in the pop-up window may be call transmission, short message transmission, multimedia message transmission, or deletion of the corresponding name tag.
The control unit 130 identifies whether a type of human contact event to be executed is selected in step S423. If a type of human contact event to be executed is selected through the input unit 150, the control unit 130 identifies a telephone number corresponding to the selected name tag in step S425, and executes the selected human contact event in step S427. For example, if call transmission is selected as the human contact event to be executed, the control unit 130 dials the identified telephone number and transmits a call through the RF communication unit 110. If message transmission is selected as the human contact event to be executed, the control unit 130 identifies a telephone number corresponding to the selected name tag and controls the display unit 140 to display an input window for preparing a message. When the user completes preparing a message and inputs a command for transmitting the message through the input unit 150, the control unit 130 transmits the input message to the identified telephone number.
If the function of displaying a log data list is selected at step S420, the control unit 130 controls the display unit 140 to display a stored log data list of the selected name tag in step S430, as shown in FIG. 6A. For example, if the user selects a name tag ‘Jane’ from the displayed tag names at step S415, upon selecting the function of displaying a log data list, the control unit 130 controls the display unit 140 to display a log data list corresponding to the name tag ‘Jane’. The control unit 130 may display a photograph corresponding to the selected name tag as a background image. The log data list may include the total human contact frequency and the frequencies of individual human contact events. The log data list may further include the number of data files containing a contact person name corresponding to the name tag. The data file may be a music file, a voice file, a memo file, a photograph or an image file containing the contact person name, stored in the mobile terminal 100.
The control unit 130 identifies whether a log data item is selected from the log data list in step S440. If the user selects a log data item from the log data list (for example, ‘2. Call’ of FIG. 6B), the control unit 130 controls the display unit 140 to display log data corresponding to the selected log data item in step S450, as shown in FIG. 6C. Here, the log data includes a type of a call, and date and time of call transmission or call reception. When displaying log data of the corresponding log data item, the control unit 130 displays each log data item in a tabular format. Therefore, when log data of a selected log data item is displayed in a screen, the user may select another log data item.
In this specification, a people cloud screen has been described as an example of displaying data in a standby screen of the mobile terminal 100. However, the people cloud screen may further display the quantities of data, such as a photograph, music, memo, and schedule data, stored by individual contact persons in the mobile terminal 100, in addition to data generated during communication with the mobile terminal 100. The people cloud screen may further display accumulated log data by selecting an optional function from a menu. The people cloud screen may be set to be displayed in the display unit 140 when a function of displaying a people cloud screen is selected from a menu.
When a name tag is selected from the people cloud screen, the control unit 130 may display statistical information for a predetermined period corresponding to the selected name tag. For example, the control unit 130 may display statistical information of how often a person has been contacted and how much data exists that is related to the contact person.
Name tags for other types of data (for example, moving picture and photograph) stored in the mobile terminal 100 may be input through the people cloud screen. For example, if the user inputs a command for assigning a name tag to a photograph, the control unit 130 controls the display unit 140 to display a people cloud screen. If the user selects a tag from the people cloud screen, the control unit 130 assigns the selected name tag to a photograph selected by the user.
According to the present invention, a user may identify a human contact frequency by using log data of a mobile terminal. That is, the user may easily identify the most frequently contacted person and the least frequently contacted person for a predetermined period by using the log data.
The log data is displayed in a user-oriented method instead of a function-related display method, and thereby the user may easily identify log data and the human contact frequency for each contact person.
While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
