## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of International Application No. PCT/CN2012/070870, filed on Feb. 3, 2012, which claims priority to Chinese Patent Application No. 201110215318.8, filed on Jul. 29, 2011, both of which are hereby incorporated by reference in their entireties.


FIELD OF TECHNOLOGY
The present disclosure relates to communication technologies, and more particularly, to a method and a terminal of displaying contact list.
BACKGROUND
With fast development of information technologies, it is increasingly easier for people to communicate with each other, and the communication methods are increasing as well, for example, to communicate through a cell phone or a fixed phone, to communicate through an electronic mail (email), to communicate through an instant messaging (IM: Instant Messaging) terminal and so on. Because of a variety of reasons, a user will communicate with more and more people, each having different contact manners. Consequently, it is almost an impossible mission for a user to remember all of the contact manners of everyone who communicates with him or her. Thus, in order to reduce memory capacity of a user and be convenient for a user to communicate with others, a conception of contact list is provided.
A contact list is usually maintained by a user himself. Contact information in the contact list includes at least two parts, one being an identifier of a contact recorded by the user, which may be a name, a nickname, a code and so on, the other being contact manner, which may be a telephone number, and/or an email address, and/or a IM account number and so on.
A prior method of displaying a contact list is based on a particular order, such as alphabetic order, Chinese pinyin alphabetic order and so on, to display contacts in the contact list. Due to limitation on the display size of a terminal screen, contacts in the contact list may need several screens to be displayed completely. Consequently, the contact list will be paged to display. If a user wants to find a particular contact, he may have to scroll several pages to find it, which leads to inconvenience for the user and degrades the user's experience.
SUMMARY

DETAILED DESCRIPTION OF THE EMBODIMENTS
Solutions in the embodiments of the present disclosure are hereinafter described in detail and completely, with reference to accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part, but not all, of the embodiments of the present disclosure. All of the other embodiments that are obtained by those skilled in the art based on the embodiments in the disclosure without any inventive efforts fall into the scope protected by the present disclosure.
First, a method of displaying contact list provided by an embodiment of the present disclosure will be introduced. The embodiment of the present disclosure provides a terminal with a touch sensitive display, which may be an apparatus with a touch sensitive display, such as a mobile phone, a tablet computer, a personal digital assistant (PDA: Personal Digital Assistant), a laptop and so on. FIG. 1 is a flow chart illustrating a contact list display method provided by an embodiment of the present disclosure, comprising:
101, detecting a touch on the touch sensitive display, after receiving an instruction for opening a contact list.
The instruction for opening the contact list may be sent by a user's operation, for example, by the user clicking a contact list menu, a contact list button and so on.
In particular, touch by finger(s) of the user with the touch sensitive display, touch by a touch pen with the touch sensitive display and so on may be detected.
102, determining a touch position, when detecting the touch on the touch sensitive display.
Each point on the touch sensitive display has a unique coordinate (x, y). Consequently, the coordinate of the touch position may be determined, when the touch on the touch sensitive display is detected.
103. determining a large contact group corresponding to the touch position, and displaying contacts in the large contact group by the touch sensitive display.
The large contact groups may be divided according to different dividing principles, in which for example, contacts may be divided into classmates, colleagues, relatives, friends and so on. Of course, contacts may also be divided according to the first words or the first letters of the contacts. Each large contact group has a corresponding index.
In particular, as the amount of large contact groups is predictable, the display positions of the indices of the large contact groups on the touch sensitive display are preset. Consequently, the correspondence between each large contact group and position on the touch sensitive display may be preset or calculated, so that the large contact group corresponding to the touch position may be determined, after the coordinate of the touch position is determined. For example, the coordinate ranges of the areas corresponding to respective large contact groups may be pre-stored. As a result, after the coordinate of the touch position is acquired, it may be directly determined which of the large contact groups has a corresponding coordinate range contains the coordinate of the touch position, and the large contact group corresponding to the touch position can be determined.
In an embodiment of the present disclosure, on the touch sensitive display, a touch area provided for a user to click and a display area for displaying the contacts may be separate. Therefore, the user clicks different areas within the touch area, while the display area displays contacts corresponding to different large contact groups. In another embodiment of the present disclosure, the touch area may be transparent or semitransparent. As such, the display area may be the whole area of the touch sensitive display. When the touch sensitive display displays contacts in a large contact group, even the contact information is displayed on the display area, it is visible to the user.
When the touch sensitive display displays the contacts, it may display only identifiers of the contacts, or may display both of the identifiers and images of the contacts at the same time. If the user does not set up images for some contacts, a default image may be used. When the touch sensitive display supports multi-touch, if there are so many contacts in a large contact group that the display area cannot display them completely at a time, the user may touch the display area, click a specific position or button to implement page scrolling for the contacts on the display area. Of course, some gestures may be preset, so as to match a touch of a user with the preset gestures when the touch of the user is detected, and therefore perform an operation corresponding to the matched gesture, such as page up, page down and so on.
It can be known from the above that the embodiments of the present disclosure may be applied on a terminal with a touch sensitive display, and contacts in the contact list have been divided into large contact groups previously according to a certain principle. As a result, when it is needed to display the contact list, as long as the touch position on the touch sensitive display is determined, the large contact group in correspondence with the touch position can be determined, so as to display the contacts in the large contact group by the touch sensitive display. As different touch positions corresponds to different large contact groups, the user may trigger to display the contacts in different large contact groups by touching different positions on the touch sensitive display, so that the user can search a contact quickly which improves the user's experience.
For example, when the shape of the touch sensitive display is a rectangle, indices of large contact groups may be placed on at least one side of the four sides of the rectangle. Particularly, in order to satisfy usages of users with various habits, in an embodiment of the present disclosure, a user may set indices of large contact groups to display on which side(s) according to his or her habit. For example, a user who gets used to left hand may set the indices of large contact groups to display on the left side; and a user who gets used to right hand may set the indices of large contact groups to display on the right side. Of course, the indices of large contact groups may also be set on an arc which uses any one angle of the four angles of the rectangle as its center. In order to satisfy usages of users with various habits, in an embodiment of the present disclosure, a user may set the indices of large contact groups to display on an arc using which angle as its center. For example, a user who gets used to left hand may set the indices of large contact groups to display on the arc which uses the left-bottom angle as its center; and a user who gets used to right hand may set the indices of large contact groups to display on the arc which uses the right-bottom angle as its center. It is convenient for the user to operate by one hand and improve the user's experience that the indices of large contact groups are set on the arc which uses the left/right-bottom angle as its center. In order to make it convenient for a user to recognize different large contact groups, the areas where the different large contact groups locate may be set with different colors, or any two adjacent areas where the large contact groups locate may be set with different colors.
Particularly, in an embodiment of the present disclosure, when the indices of large contact groups are set to display on an arc which uses one of the four angels of the rectangle as its center, the determination of the large contact group corresponding to the touch position may comprise determining a degree of an angle made by a datum line and a line joining the touch position and a datum mark, matching the degree of the angle and preset degree ranges of large contact groups, so as to obtain the large contact group corresponding to the touch position. The datum mark may be the point where the center locates, and the datum line may be any one of the two sides of the angle.
In an embodiment of the present disclosure, contacts in the contact list are divided into 27 large contact groups according to the first pinyin letters as the indices. The indices of the 27 large contact groups are A-Z and #, wherein contacts in the “#” are the ones who cannot be divided into the large contact groups corresponding to A-Z, such as those contacts which start with numbers, special signs and so on.
FIG. 2 illustrates a display instance in which the touch sensitive display is a rectangular, and when the first pinyin letters which are used as the indices are displayed on an arc which uses the right-bottom angle as its center, the large contact group corresponding to “L” corresponds to the touch position. As shown in FIG. 2, contacts in the large contact group corresponding to “L” are Luyi, Linglin, Lan, Lili, Li, Lirui, Liuyong and so on. In an embodiment of the present disclosure, in order for a user to confirm which large contact group is displayed more easily, the currently displayed index of the large contact group may be highlighted, wherein the method of highlight may be to display an enlarged index of the large contact group, to display with different colors, or the like. The embodiments of the present disclosure do not limit the specific methods of highlight. It will not affect the implementations of the present disclosure as long as a user can easily confirm which large contact group is displayed currently. As shown in FIG. 2, L is highlighted.
FIG. 3 illustrates a display instance in which the touch sensitive display is a rectangular, and when the first pinyin letters which are used as the indices are displayed on an arc which uses the right-bottom angle as its center, the large contact group corresponding to the “S” corresponds to the touch position. As shown in FIG. 3, contacts in the large contact group corresponding to the “S” are Saralin, Shenghao, Shasha, Songqing, Shencheng, San, Sumi and so on. In order for a user to confirm which large contact group is displayed more easily, as shown in FIG. 3, S is highlighted.
The case has been described above in which contacts in the contact list are divided into large contact groups in the embodiments of the present disclosure. In another embodiment of the present disclosure, contacts in a large contact group may be further divided into at least two small contact groups after being divided into large contact groups. For example, after the contacts are divided into classmates, colleagues, relatives, friends and other large contact groups, the contacts in the large contact group of classmates can be divided into at least two small contact groups according to the first words or the first letters, or the contacts in the large contact group of classmates may be divided into at least small contact groups according to contact relationship values, such as, being divided as frequently-contacted or infrequently-contacted; or being divided as frequently-contacted, occasionally-contacted and infrequently-contacted. For example, after the contacts are divided into at least two large contact groups according to the first words or the first letters of the contacts, the contacts in each large contact group may be further divided into at least small contact groups according to contact relationship values, such as, being divided as frequently-contacted or infrequently-contacted; or being divided as frequently-contacted, occasionally-contacted and infrequently-contacted, and so on.
When the contacts in the large contact group are divided into at least two small contact groups according to the relationship values of the contacts, the contacts in the large contact group may be divided into small contact groups by the following method: calculating contact relationship values of the contacts in a large contact group; adding the contacts into a corresponding small contact group, according to the contact relationship values and preset ranges of contact relationship values corresponding to the small contact groups. In an embodiment of the present disclosure, contact relationship values of the contacts are obtained by a terminal background performing statistics on communication records. The relationship value of a contact may be determined according to the frequency in which the user communicates with the contact. For example, in an embodiment of the present disclosure, the terminal background will calculate the contact relationship value R in the latest 30 days, and the time frame is the latest 30 days. The factors affecting the contact relationship value R comprise: A=telephone, B=text message, Z=interaction; weights of the respective factors are: A=1, B=0.5, Z=0.5; the calculation time frame is the latest 30 days, wherein the frequency of the latest 10 days takes 70% proportion, and the frequency of the earlier 20 days takes 30% proportion; wherein contact frequency Q10 denotes the average frequency in the latest 10 days, and Q20 denotes the average frequency in the earlier 20 days, and then the frequencies corresponding to the respective factors may be expressed as: Qa10, Qb10, Qz10; Qa20, Qb20, Qz20 respectively. An embodiment of the present disclosure provides a calculation formula for contact relationship value R as given below:

R=(A*Qa10+B*Qb10+C*Qz10)*10*0.7+(A*Qa20+B*Qb20+C*Qz20)*20*0.3

where R≧0 and R≦100. The value 100 is selected when the value of calculated R>100.

Consequently, the large contact group is divided into at least two small contact groups. After determination of the large contact group corresponding to the touch position, an embodiment of the present disclosure further includes determining a small contact group from the large contact group corresponding to the touch position, in which case, display of the contacts in the large contact group by the touch sensitive display includes displaying the contacts in the small contact group of the large contact group by the touch sensitive display.
There are many ways to display the indices of the small contact groups. For example, when the indices of the large contact groups are displayed on the left side or the right side of the touch sensitive display, the indices of the small contact groups may be displayed on the top side or the bottom side of the touch sensitive display. Accordingly, when the indices of the large contact groups are displayed on the top side or the bottom side of the touch sensitive display, the indices of the small contact groups may be displayed on the left side or the right side of the touch sensitive display.
When the indices of the large contact groups are displayed on an arc which uses one of the four angels of the touch sensitive display as its center, the sector which is defined by the indices of the large contact groups and the two sides of the angle may be divided into a sector and at least one sector ring, each sector or sector ring displaying an index of a small contact group. In this case, determination of the small contact group of the large contact group corresponding to the touch position comprises: determining a distance between the touch position and a datum mark, and matching the distance and preset distance ranges of small contact groups, so as to obtain the small contact group in correspondence with the touch position. Areas of different small contact groups may be set with different displaying colors, or any two adjacent areas where the small contact groups locate may be set with different colors, in order for a user to distinguish different small contact groups conveniently.
It may be understood that coordinate ranges of the areas of the respective small contact groups may also be preset. Thus, coordinate of the touch position may be matched with the coordinate ranges of the areas of the respective small contact groups, after determination of the coordinate of the touch position, so as to determine the small contact group corresponding to the touch position.
In an embodiment of the present disclosure, contacts in the contact list are divided into 27 large contact groups according to the indices which are the first letter of pinyin. The indices of the 27 large contact groups are A-Z and #, and contacts in each large contact group are divided into three small contact groups, frequently-contacted, occasionally-contacted and infrequently-contacted according to contact relationship values.
FIG. 4 illustrates a display instance in which the touch sensitive display is a rectangular, and when the first pinyin letters are displayed as the indices of the large contact group on an arc which uses the right-bottom angle as its center, and the indices of the small contact groups are displayed on a sector or sector ring, the large contact group corresponding to the “L” corresponds to the touch position and the small contact groups corresponds to “frequently-contacted”. As shown in FIG. 4, the displayed contacts in the “frequently-contacted” small contact group of the large contact group corresponding to the “L” include Luyi, Linglin, Lan, Lili, Li, Liuyong and Lirui and so on. In order for a user to distinguish different small contact groups, the sector areas corresponding to the small contact groups of “infrequently-contacted”, “occasionally-contacted” and “frequently-contacted” may corresponds to different colors, or gray levels, or transparencies and so on, so that the user may locate different small contact groups accurately. There is further an “ALL” area in FIG. 4. If the user clicks this area, only the contacts in the large contact groups will be shown, and no matter these contacts belong to which small contact groups. In order for the user to determine which large contact group is currently displayed more easily, as shown in FIG. 4, L is highlighted. Further, in order for the user to determine which small contact group is currently displayed more easily, the currently displayed small contact group may be highlighted, wherein the method of highlight may be to present a tag in the area of the current small contact group, highlight the area of the current small contact group, or the like. The embodiments of the present disclosure are not limited to the specific methods of highlight. It does not affect the implementations of the present disclosure as long as it enables the user to determine easily which small contact group is displayed currently. As shown in FIG. 4, a tag is presented in the area corresponding to frequently-contacted.
FIG. 5 illustrates a display instance in which the touch sensitive display is a rectangular, and when the first pinyin letters are displayed as the indices of the large contact group on an arc which uses the right-bottom angle as its center, and the indices of the small contact groups are displayed on a sector or sector ring, the large contact group corresponding to the “L” corresponds to the touch position and the small contact group corresponds to “occasionally-contacted”. As shown in FIG. 5, the displayed contacts in the “occasionally-contacted” small contact group of the large contact group corresponding to the “L” include Lianxin, Liuzhilan, Liushuangshuang, Liangwen, Linling, Liuming, Lilei and so on. In order for the user to determine which large contact group is currently displayed more easily, as shown in FIG. 5, L is highlighted. Further, in order for the user to determine which small contact group is currently displayed more easily, as shown in FIG. 5, a tag is presented in the area corresponding to occasionally-contacted.
