In the information locating method of the present invention, after receiving the first initial letter of the information name input by the user, only the second initial letter of the item matching the first initial letter with the letter entered by the user is used. The corresponding button prompts to the user, and the method for prompting the user may be displayed in the virtual keyboard area, such as displaying the characters of the virtual keyboard as "available" and "not available", and the "available" state is reflecting the characters of the keyboard. Highlight the button, the status of "not available" is that the character of the keyboard is grayed out, or it can be displayed on the physical keyboard, so that the button corresponding to the next matching initial letter is displayed as "available", and other letters correspond. The display is displayed as "not available"; or the next matching initial is displayed directly on the screen by a text entry. Therefore, the user can accurately and quickly click the button corresponding to each initial letter of the information, thereby increasing the input rate and the rate at which the contact is located.

The name of the information here can include a variety of situations, such as the name of a contact in a cell phone or PDA, such as a place name in a computer, a restaurant name, and the like. Let's take a look at the contact name in the phone or PDA as an example to illustrate this information location method.

3 to FIG. 6 are schematic diagrams of contact location in a third embodiment of the present invention. As shown in FIG. 2 to FIG. 5, in the third embodiment of the present invention, the letter code corresponding to each initial letter of the contact name is sequentially input. Quickly find contacts in the people database.

First save more than one contact name;

An entry containing each of its initials is created for the contact name, wherein the order of the initials is the same as the arrangement of the initials in the contact name, and Table 1 is a correspondence table between the contact name and the entry containing each of the initials. The entry containing the initials of the contact name is an entry containing the initial letter code of the contact name.

- ' - This assumes that the terminal at this time has the function of a touch screen. When the contact is located in the 26-letter virtual keyboard area of the touch screen operation interface of the contact, as shown in Figure 3 to Figure 6, when "Lianyiwu" is located, 26 The letter keys will display the characters of the keyboard as "available" and "not available" according to the contact name entries in each, and the "available" state is a state in which the characters of the keyboard are highlighted, and the "unusable" state is displayed. The color of the keyboard is not grayed out.

For example: Find "Li Yiwu", make sure that the user enters "L" in the search box of the touch screen operation interface, and finds the entry of the first word with the first letter "L" in all the entries, in the contact list. , only the first entry with the first letter "L" in all entries is displayed. Here, the entry in this contact list can be called the first entry set, where the first entry set is: "LH", "LJ ", "LXE", "LYT", "LS", "LYW", "LC", and prompt the user with the second initial of all entries in the first item set, ie only display 'in the input disk'Ή", T, "X,,""Y,,,"S,,,"C" select alphabetic keys; then determine that the user input is "Y", find the second initial from the first set of entries The entry of "Y" is called the second set of entries, where the second set of entries is "LYT", "LYW", in which case there is not only one entry in the second set of entries, but all the initials in the entry It is not required to be the same as the "LY" input by the user. Only the "T" and W" optional letter buttons are displayed in the input disk, and the third initial letter entered by the user is continued. "W", then find the third entry with the first letter "W" in the second set of entries, and become the third entry, where the third entry is set to "LYW", in which the second entry is both There is only one entry, and the item in the entry The first letter is the same as the "LYW" input by the user, that is, the information to be found is located. You can also use the following contact location method. For example, look for "Li Yi Wu" as an example. The process is as follows: Make sure that the user searches for the first word in all the entries after entering "L" in the search box of the touch screen operation interface. The entry with the initial letter "L", in the contact list, only the first entry with the first letter "L" in all the entries. Here, the entry in this contact list can be called the first entry set. , where the first set of entries is: "LH", "LJ", "LXE", "LYT", "LS", "LYW", "LC", and the second of all entries in the first entry set The first letter prompts the user, that is, only the "H", ' _τ ,, " _χ , , , " _γ , , , " _s , , , "c" optional letter buttons are displayed in the input disk; then the user input is determined as 'Ύ', find the first two entries in the entry whose initials are "LY". In the contact list, only the first two entries with the first letter "LY" in all entries are displayed, called the second entry. , where the second set of entries is "LYT", "LYW", in which there is more than one entry in the second set of entries, and all the entries in the entry The "LY" input by the parent and the user is not required to be the same. Only the "T" and W" optional letter buttons are displayed in the input disk. Continue to determine that the third initial letter entered by the user is "W", and find in all entries. The first three entries with the initial "LYW" become the third entry, where the third entry is set to "LYW", in which case there is only one entry in the third set of entries, and all the initials in the entry are The "LYW" entered by the user is also the same, that is, the information to be found is located.

If it is an English name, it can be filtered by the initials of the English name or by consecutive letters. For example, Luke Haines can be searched by the initials "LK" in English, or by continuous letter search, such as setting "Luke".

7 to FIG. 10 are schematic diagrams showing contact location in a fourth embodiment of the present invention. As shown in FIG. 6 to FIG. 9, according to a fourth embodiment of the present invention, a digital code corresponding to the first letter of the contact name is input in the contact. Quickly find contacts in the database.

Here again, it is assumed that the terminal at this time has the function of a touch screen. When the contact is located in the nine digital virtual keyboard areas of the touch screen operation interface of the contact, when the "Eight Five" is located in FIG. 7 to FIG. 10, 9 numbers are The button will display the characters of the keyboard as "available" and "not available" according to various contact name entries. The "available" state is a key for highlighting by keyboard. The status of "not available" is The characters on the keyboard are grayed out and cannot be pressed. First save more than one contact name;

Create an entry containing the initials of the contact name, wherein the order of the initials is the same as the arrangement of the initials in the corresponding contact name, and Table 2 is the correspondence table between the contact name and the entry containing each of the initials. The entry containing the initials of the contact name is an entry containing the first alphanumeric code of the contact name, and the corresponding manner of the initial letter and the digital code may be in a corresponding manner of a conventional telephone, such as the letter corresponding to the digital code 2" ", "b", "c", the numeric code "3" corresponds to the letters "d", "e,,, "f", and so on.

Table II

For example: Find "Li Yiwu", make sure that the user enters "5" in the search box of the touch screen operation interface, and finds the entry of the first word with the first letter "5" in all the entries, in the contact list. , only the first entry with the first letter of "5" in all entries is displayed. Here, the entry in this contact list can be referred to as the first set of entries, where the first set of entries is: "54", "55 ", "593", "598", "57", "599", "52", and prompt the user with the second initial of all entries in the first entry set, ie only "displayed on the input disk"2","4","5","9","7" optional letter buttons; then determine the user input is "9", find the second initial letter "9" from the first item set The entry, called the second set of entries, where the second set of entries is "593", "598", "599", in which case there is more than one bar in the second set of entries. And all the initials in the entry are not required to be the same as the "59" entered by the user. Only the "3", "8", 9" optional letter buttons are displayed in the input disk, and the third input from the user is continued. The first letter is "9", then the third item in the collection looks for the third entry with the initial "9", which becomes the third entry, where the third entry is "599" and the second entry There is only one entry in the collection, and all the initials in the entry are the same as the "599" entered by the user, that is, the information to be searched.

You can also use the following contact location method. For example, look for "Li Yi Wu" as an example. The process is as follows: Make sure that the user searches for the first word in all the entries after entering "5" in the search box of the touch screen operation interface. The entry with the initial letter "5", in the contact list, only the first entry with the first letter "5" in all the entries is displayed. Here, the entry in this contact list can be called the first entry set. , here the first set of entries is: "54", "55", "593", "598", "57", "599", "52", and the second of all entries in the first entry set The first letter prompts the user, that is, only the "2", "4", "5", "9", "7" optional letter buttons are displayed in the input disk; then it is determined that the user input is "9", and the search is performed again. The first two entries in the entry whose initials are "59". In the contact list, only the first two entries in the first two initials of "5Y" are displayed, called the second entry, where the second entry is set. "593", "598", "599", at this time there is more than one entry in the second item set, and all the initials in the item are The "59" entered by the user is not required to be the same. Only the "3", "8", and 9" optional letter buttons are displayed on the input disk. Continue to determine that the third initial letter entered by the user is "9" in all entries. Find the first three entries with the initial "599" and become the third entry. Here, the third entry is set to "599". At this time, there is only one entry in the third set, and all the entries in the entry. The letters are the same as the "599" entered by the user, that is, the information to be found is located.

When the contact you need to find is not sure of the full name, you can find it by entering a wildcard. For example: If the user wants to find "Li Yiwu", but only knows "Yiwu", and is not sure of the contact's last name, he can enter the matching symbol "?" indicating the fuzzy character of a single character in the search box. All the keys in the virtual keyboard are displayed as "available" status or only the key symbols corresponding to the letter or numeric code of the second letter of all the initials of the contact database stored in the contact database are displayed as "available"state; , enter the letter code or the numeric code "Y" or "9" of the known second letter, and the mobile terminal selects the letter or digit code of the second letter of the contact name as "Y" or "9" Record, in the contact list, Only the contact data records with "Y" or "9" in the corresponding location in the contact library are displayed. In the virtual keyboard, the contact library is displayed with "Υ" or "9" as the second initial letter. Record, as in the contact list in the first embodiment, at this time, the "T" and "W" buttons in the virtual keyboard display "available", or in the contact list in the first embodiment, at this time the virtual keyboard is "8", " The 3" or "9" button displays "Available"; finally, after entering "W" or "9", it is positioned to "Li Yiwu". The exception can also set a string match indicating that the number of matches is not limited. Assume that the user wants to find "Li Yiwu" at this time, but the user only determines the contact name "Li" at this time, but the name of the contact is not To be sure, the user can wait for the terminal to display the next matching letter after entering "L" first, and can also directly input "L*". At this time, the screen will directly locate "Li San" and "Li Yiwu". " At the office, the user is choosing as needed.

In the above embodiments, we only refer to the entry as the initial letter code or numeric code of the contact name. In practical applications, many users will set the identifiers in front of the contact name as needed. In this case, the positioning The manner is similar to that of the first embodiment and the second embodiment, except that in the correspondence table at this time, other identifiers are included in addition to the letter code or the digital code.

In the following, the correspondence table between the contact name and the initials of the contact name is the letter code correspondence table of the contact name and the initial letter of the contact name, indicating the special case. Suppose that the user adds the identifier "W" before "Li Day", the identifier "1" before "Li San", and the identifier "#" before "Yulong". The contact correspondence table at this time is as follows:

Luke Johnstone LJ At this time, if the user wants to find "#宇龙", the user first inputs #, and the subsequent terminal operates as in the first embodiment.

11 is an information positioning apparatus in Embodiment 5 of the present invention, as shown in FIG. 11, including a database.

1101, an input module 1102, a comparison module 1103, a prompting module 1104, and a determining module 1105.

The database 1101 saves more than one name of the information to be queried, and creates an entry containing the initials for each name of the information to be queried, wherein the order of the initials is the same as the arrangement of the initials in the corresponding names. Here, an entry containing the letter code corresponding to each of the initial letters may be created for each name of the information to be queried, or an entry containing the digital code corresponding to each of the initials may be created for each name of the information to be queried.

The input module 1102 determines the letters entered by the user, where the letters correspond to the entry types in the database 1101. If the entries in the database 1101 are alphabetic code entries, the letters entered here are alphabetic codes, if the entries in the database 1101 are numbers For the code entry, the letter entered here is a numeric code.

After the input module 1102 determines the first letter input by the user, the matching module 1103 searches for an entry in which the first letter of all the entries in the database 1101 matches the letter input by the user by the input module 1102, and is the first item set; At the same time, the second letter of all the items in the first item set is output to the prompting module 1104, and the prompting module 1104 prompts the user. After the input module 1102 determines the second letter input by the user, the matching module 1103 searches for an entry in which the second letter of all the entries of the first item set matches the letter entered by the user, and is the second item set. .

The determining module 1105 determines whether the final set of items found has only one item, or finally indicates that the information to be queried has been located at this time, and the name of the information to be queried corresponding to each item in the finally found item set is outputting the prompting module. 1104, the prompting module 1104 prompts the user, otherwise the notification matching module 1103 outputs the third letter of all the entries in the second item set to the prompting module 1104, and the prompting module 1104 prompts the user.

At this point, the input module 1102 continues to determine the third letter entered by the user, and the subsequent processing is the same as above. The determining module 1105 determines that the information to be queried has been located, and outputs the prompting module 1104 of the name of the information to be queried corresponding to each entry in the finally found item set, and the prompting module 1104 prompts the user.

Here, after the input module 1102 determines the second letter input by the user, the matching module 1103 also finds an entry in which the first two letters of all the entries match the first two letters entered by the user, and is the second set of entries.

At this time, the judging module 1105 also judges whether the finally found item set has only one item, or finally finds whether all the letters in each item in the item set are the same as all the letters input by the user, and if so, it indicates that the content has been positioned at this time. The information of the query, the name of the information to be queried corresponding to each item in the final set of items is outputted to the prompting module 1104, and the prompting module 1104 prompts the user, otherwise the notification matching module 1103 will list all the items in the second item set. The third letter is output to the prompting module 1104, which is prompted by the prompting module 1104.

At this time, the input module 1102 continues to determine the third letter input by the user, and the subsequent processing is the same as above, until the determining module 1105 determines that the information to be queried has been located, and the name of the information to be queried corresponding to each entry in the finally found item set. The output prompting module 1104 is presented to the user by the prompting module 1104.

In conclusion, the above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
