BACKGROUND OF THE INVENTION
The present invention relates to a function determination method that simplifies key operations when inputting functions and characters in a terminal having a limited number of keys, and a portable communication terminal that simplifies key operations when inputting functions and characters.
[0002]
[Prior art]
At present, mobile communication terminals such as mobile phones, PHS (Personal Handy-phone System), PDA (Personal Digital Assistants) and the like are widely used as Internet connection tools that are most familiar to users.
Currently, the functions installed in mobile communication terminals are steadily increasing, but on the other hand, in order to improve the portability of the terminals, the size and weight have been reduced, and the number of operation keys has increased accordingly. Limited.
As described above, while the number of installed functions increases, the number of operation keys for operating these functions still does not increase. As a result, many functions must be assigned to one key. Therefore, the user has to perform various operations while selecting functions assigned to these keys depending on the application.
[0003]
[Problems to be solved by the invention]
For example, a frequently used function is transmission / reception of electronic mail. When sending an e-mail, it is mandatory to enter the address to which the e-mail is sent. This e-mail address consists of letters, symbols, numbers, etc. The input operation had to be performed while switching the mode several times.
In addition, since the character input mode can be toggled between kanji, half-width kana, full-pitch kana, alphabetic, numeric, and symbol modes, key operations are very complicated when the input mode is frequently switched. There were drawbacks such as.
In addition, unlike the case of alphanumeric input, the symbols assigned to each manufacturer and the display order of the symbols may be different, which makes it very difficult for the user to use the symbols.
[0004]
The present invention has been made in view of such circumstances, and when inputting an e-mail address, by automatically interpolating an identification symbol or the like common to any e-mail address, the burden on the user in character input An object of the present invention is to provide a mobile communication terminal that can reduce the risk and can be easily handled.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a set of symbols for distinguishing two or more pieces of identification data for designating a transmission destination in an electronic mail address in a portable communication terminal having an electronic mail transmission / reception function. A storage means in which the body is stored as address complement information, an address complement information read means for reading the address complement information from the storage means when any key is operated when an e-mail address is input, and an operation There is provided a portable communication terminal comprising: character detection means for detecting a character assigned to the key, and display control means for displaying the address complement information following the detected character.
[0006]
For example, the two or more pieces of identification data for designating the transmission destination include a user name, a domain name, a subdomain name, an organization ID, a country ID, and the like. "@ (At mark)" that distinguishes a user name and a domain name, and ". (Dot)" interposed between a domain name and an organization ID, or between an organization ID and a country ID. Etc. ". The number of dots constituting the aggregate is 1 or 2 or 3.
The address complement information reading unit, the character detection unit, and the display control unit described above are processes performed by the CPU 12 executing a program stored in the ROM 9.
[0007]
According to such a configuration, when the input of the first character is detected when the e-mail address is input, the predetermined address supplement information selected in advance is automatically set to the character selected as the first character. Display in a complementary form. Thereby, it is possible to simplify the input operation of the e-mail address, reduce the input burden on the user, and provide an easy-to-use portable communication terminal.
[0008]
In the mobile communication terminal, the address supplement information is information that can be deleted, changed, or added by a user.
Thus, by making it possible to arbitrarily change the setting of the address interpolation information, it is possible to further enhance the information to be interpolated, thereby further reducing the burden of the user's key operation when inputting the mail address.
[0009]
Further, in the mobile communication terminal described above, the storage means stores a plurality of address complement information, and the address complement information read means is operated by any key when inputting an e-mail address. In this case, the predetermined address complement information designated in advance is read from the storage means.
As described above, the storage means stores a plurality of pieces of address supplement information, and when an e-mail address is input, if any key is operated by the user, a predetermined designation specified by the user in advance is made. Since the address complement information is supplemented to the currently entered email address, it is possible to further complement the email address according to the user's wishes, thereby further reducing the input burden on the user. .
[0010]
Further, in the mobile communication terminal described above, the storage means stores a plurality of address complement information, and the address complement information read means is operated by any key when inputting an e-mail address. In this case, all the address complement information stored in the storage means is read out, and the display control means displays all the read address complement information as a list on the display unit as an option, and any address complement information is displayed. When the information is selected by the user, the selected address completion information is displayed following the detected character.
Thus, a plurality of address supplement information is stored in the storage means, and when any key is operated by the user at the time of inputting an e-mail address, a plurality of information currently stored in the storage means is stored. The address complement information is displayed as an option to prompt the user to select the desired one. When any address supplement information is selected by the user, the selected address supplement information is supplemented to the currently input e-mail address, so that the address supplement information always meets the user's request. Can be selected, and the input burden on the user can be greatly reduced.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a mobile communication terminal according to an embodiment of the present invention, and FIG. 2 is an overview diagram of the mobile communication terminal.
In FIG. 1, reference numeral 1 denotes an RF unit having an antenna 2, which transmits transmission data on a carrier wave and transmits it from the antenna 2, and outputs an incoming signal received via the antenna 2. Reference numeral 3 denotes a codec, which decodes and outputs data input from the RF unit 1, while encoding data input from the CPU 12 and outputs the encoded data to the RF unit 1. Reference numeral 4 denotes a microphone that converts an externally input audio signal into an analog signal and outputs the analog signal to the CPU 12. Reference numeral 5 denotes a speaker that outputs the audio signal output from the CPU 12 as audio. Reference numeral 6 denotes display data supplied from the CPU 12. Is a display unit including a liquid crystal display or the like.
[0012]
Reference numeral 7 denotes an operation unit including a numeric keypad 7a for inputting a telephone number, characters, and the like, and a function key 7b to which various functions are assigned. A plurality of characters are assigned to the operation keys 100, 101, 102,... Constituting the numeric keypad 7a as shown in FIG.
[0013]
Reference numeral 8 denotes a key press detection unit that detects the press of each operation key constituting the operation unit 7, and outputs information on the pressed operation key to the CPU 12 when the press of the operation key is detected.
[0014]
Reference numeral 9 is a ROM (read on memory) in which various programs executed by the CPU 12, function information assigned to each operation key, and the like are stored, and reference numeral 10 is a RAM (random access memory) for data storage. The CPU 12 (central processing unit) performs predetermined processing by reading and executing various programs stored in the ROM 9. In addition, data is temporarily stored in the RAM 10 during the process.
[0015]
In a predetermined memory area of the ROM 9, character information assigned to each operation key is stored in association with the number of times the operation key is pressed. Thereby, the CPU 12 can detect the corresponding function / character based on the pressed operation key and the number of times the operation key is pressed.
[0016]
The RAM 10 stores various address complement information.
Many of the e-mail addresses currently used are “user name” + “@ (at sign)” + “domain name” + “. (Dot)” + “organization ID” + “. (Dot)” + “ Furthermore, “co” and “ne” can be cited as examples of the organization ID widely adopted in the country, and “jp” can be cited as the country ID.
Address complement information is an identification data for specifying a transmission destination in the e-mail address having the above configuration, a symbol for distinguishing each of a user name, a domain name, a subdomain name, an organization ID, and a country ID “@ (At mark)” and “. (Dot)”, for example, “@ ..”, “@ ...”. In addition to these address completion information, for example, “@ .co.jp”, “@ .ne.jp”, “@ .com”, which are information common to email addresses, are registered in advance as address completion information. By doing so, it is possible to enhance supplementary information at the time of e-mail input.
[0017]
The address supplement information may be information stored in advance in a non-rewritable memory such as the ROM 9 at the time of manufacture / design of the mobile communication terminal, or may be a rewritable nonvolatile memory. It may be information stored in advance in the RAM 10 or the like. It is also possible that the user can arbitrarily add or change registration after sales. In this case, it is necessary to further provide a mode for registering address complement information in the terminal.
[0018]
Next, an e-mail address input process of the mobile communication terminal having the above configuration will be described.
First, before performing the e-mail address input process described below, the user performs an operation for designating the most frequently used address completion information among one or more address completion information stored in the ROM 9 or the RAM 10. . Note that the address complement information specified here is valid until this designation operation is performed again by the user and the specified address complement information is changed.
[0019]
Subsequently, when creating a new e-mail, the user changes the mode to the new e-mail creation mode by operating the function key 7b (see FIG. 2), and then selects an e-mail address input field. By doing so, an e-mail address is input.
For example, when the address to be input by the user is “abcde@efg.ne.jp”, the user first presses a predetermined key of the function key 7b to change the character input mode. Set English input mode. It should be noted that the character input mode may be automatically switched to the English input mode by selecting the input field for the e-mail address.
Subsequently, the operation key 101 corresponding to the first character “a” of the mail address is pressed to input the destination address of the electronic mail.
[0020]
When such an operation is performed, first, the key press detection unit 8 in the mobile communication terminal detects that the operation key 101 is pressed, and notifies the CPU 12 of pressing of the operation key 101. Upon receiving the press notification, the CPU 12 reads “a”, which is a character corresponding to the case where the operation key 101 is pressed once from the ROM 9, and the CPU 10 further specifies the current designation from the address complement information stored in the ROM 9 or RAM 10. The address completion information, for example, “@ ..” is read out.
Then, “a @...” With address supplement information “@...” Added to the read character “a” is displayed on the display unit 6.
[0021]
The user continues to input the e-mail address while checking the display screen. For example, since the input character “a” has not yet been determined at the present time, by depressing the confirmation key, “a” is confirmed, and then an e-mail address input operation is performed.
When inputting a domain name, organization ID, or country ID, the cursor is moved to the input position and a character input operation is performed.
When the address complement information to be complemented is an incorrect input, the user can delete the automatically complemented address complement information by operating the clear key.
[0022]
As described above, according to the present embodiment, when the input of the first character is detected at the time of inputting the e-mail address, the predetermined address supplement information selected in advance is continued to the first character. Since the display is performed in a complemented form, the user input process can be omitted, the input burden on the user can be reduced, and an easy-to-use portable communication terminal can be provided.
[0023]
<< Second Embodiment >>
Next, a mail address input process according to the second embodiment of the present invention will be described.
In the first embodiment described above, the case where the user preliminarily specifies the address complement information to be complemented when the mail address is input has been described. However, in this embodiment, the CPU 10 inputs the first character by the user. When it is detected, all the address complement information stored in the ROM 9 or the RAM 10 is read, and this information is displayed as a list on the display unit 6 as options. When any address supplement information is selected by the user, the mail address complemented with the selected address supplement information is displayed on the display unit 6.
As a result, the user can select the corresponding information from the currently registered address supplement information when inputting the e-mail address, so that the address supplement information can be used more effectively than the first embodiment described above. can do.
[0024]
In addition, except for the supplemented information, the mail addresses are often composed of alphabets. Accordingly, the user can input a mail address without switching the character input mode such as kana, numbers, alphabets and the like.
In this way, the user can input address completion information as an e-mail address simply by specifying one of the displayed address completion information. It is not necessary to do anything at all, and it becomes possible to input an e-mail address very easily.
[0025]
As described above, according to the present embodiment, when the input of the first character is detected when the e-mail address is input, all registered address supplement information is presented to the user, When the address completion information is selected, the selected address completion information is complemented to the input e-mail address. Therefore, compared with the first embodiment, the range of use of the address completion information can be expanded. Thereby, it becomes possible to reduce a user's input burden more.
[0026]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design and the like within the scope not departing from the gist of the present invention.
[0027]
【The invention's effect】
