Description
DESCRIPTION
Portable Terminal Character Selectively In~uttina Device and Character Selectively In~uttina Method Technical Field The invention relates to a portable terminal apparatus which enables characters to be inputted and to a character selection input apparatus and a character selection input method which are suitable for use in character input of the portable terminal apparatus.
Background Art There is a case where characters are inputted to a portable terminal apparatus such as a pager. In the portable terminal apparatus such as a pager, a number of keys cannot be arranged in order to realize a small size and a light weight and to improve operating efficiency. In the pager in which a number of keys cannot be arranged as mentioned above, hitherto, the following character input methods have been considered.
First, there is considered a method such that when a predetermined button is depressed, one character candidate is displayed at an input position, when this button is further depressed, the next character candidate is displayed, and when the user continuously depresses the predetermined button until a desired character is displayed, the desired character is inputted. Such a method has an advantage that the character input can be performed by one key.
According to the above method, however, since the predetermined button is continuously depressed until the desired character is displayed, ire the worst case, the user needs to continuously depress the key the number of times as many as the number of characters (for example, in case of Japanese, 50 tones + numerals, symbols, and the like) in order to input the desired character, so 'that the operating efficiency is not good.
As another method, there is considered an input method such that about ten characters serving as candidates are displayed in a partial area of a screen and the user searches a desired character among the character candidates and selects this character, thereby performing a character input. According to such a method, since the desired character can be selected among the characters serving as candidates, the number of operating times of the key is reduced and the operating efficiency is improved as compared with the foregoing method of displaying the next character candidates one by one each time the button is depressed.
In the method, however, a key to select a 3 < CA 02284289 1999-09-20 desired character among the displayed characters is needed besides the key to display characters serving as candidates, so that there is a problem that the number of keys increases. Although it is considered to use right/left keys or up/down keys as a key to select the desired character, in case of using the right/left keys and up/down keys, it is necessary to arrange at least four or more keys. When the character is selected by the right/left keys or up/down keys, an erroneous operation easily occurs.
There is a pager having a rotary knob constructed by a rotary encoder and a switch. It is considered to performed the character input by using the rotary knob.
That is, according to such a method, characters in one character group are displayed in a part of a display area. The user selects a desired character among the characters in the character group by using the rotary knob comprising the rotary encoder and the switch. When the desired character does not exist in the character group, the character group is switched to the next one. When the character group is switched, characters in the next character group are displayed. The user selects the desired character among the characters of the next character group by using the rotary knob comprising the rotary encoder and the switch. When the desired character does not exist in the character group, the character group is further switched to the next one.
According to the above method, since the character can be inputted without using any key, the operating efficiency is improved.
When a plurality of character groups are switched, however, the operation to switch the character group is needed. Therefore, the character input cannot be performed by only the rotary knob. It is necessary to provide a key for switching the r_haracter group and to switch the character group by operating the key.
It is, therefore, an object of the invention to provide a portable terminal apparatus which can perform a character input without needing a key and a button with good operating efficiency and a character selection input apparatus and a character selection input method which are suitable for use in character input of the portable terminal apparatus.

Best Mode for Carrying Out the Invention An embodiment of the invention will now be described hereinbelow with reference to the drawings.
Fig. 1 shows an external construction of a pager 1 to which the invention is applied. As shown in Fig. 1, a display 2, a rotary knob 3 comprising a rotary encoder and a switch, and an escape key 4 are provided for the pager 1 to which the invention is applied.
The display 2 is used to display instruction marks indicative of various setting states or operating states or display characters of received messages or characters of a memo.
Fig. 2 shows a display screen of the display 2. Various instruction marks 51 to 57 are displayed on the display 2.
The instruction mark 51 indicates whether the pager exists in a service area or not. The instruction mark 52 shows that the received message is a locked message. The instruction mark 53 indicates the presence of a message which is not read yet. The instruction mark 54 indicates that a battery capacity :is lacking. The instruction mark 55 shows that an alarm clock has been set. The instruction marks 56 and 57 denote that the displayed message continues upward or downward. An instruction mark 58 indicates that when a reception sound is generated upon reception. An instruction mark 59 shows that a vibration is generated upon reception.
Display areas 60 to 62 are also provided for the display 2. The display area 60 displays date and a message number. Date is displayed in the area 60 in a standby state. When the hour is displayed in a 12-hour mode, "AM" or "PM" is displayed in the display area 61.
Characters of the message or memo are displayed in the display area 62. As a display area 62 for character display, for example, an area of up to 80 characters of four lines in which one line is constructed by 20 characters is assured.
In Fig. l, the rotary knob 3 is used to scroll the display of the display 2 or select items.
As will be described hereinlater, a memo function to store telephone numbers, names, and the like is provided for the pager 1 to which the invention is applied. The rotary knob 3 is used even for a character input when the memo function is used.
The rotary knob 3 is constructed by the rotary encoder and the switch. The depressing operation as shown by an arrow 5 in Fig. 3A and the rotating operation as shown by arrows 6 in Fig. 3B can be performed. When the display on the display 2 is scrolled or the item is selected, the rotating operation as shown in Fig. 3B is used. When the selected item is set, the depressing operation as shown in Fig. 3A is used.
The escape key 4 is used for the operation to turn on the pager or return to the previous picture plane.
Fig. 4 shows an internal construction of the pager 1 to which the invention is applied.
In Fig. 4, radio waves which are transmitted from a pager company are received by an antenna 11. A
reception signal of the antenna 11 is supplied to a receiving unit 12. The reception signal of a predetermined carrier frequency is selected by the receiving unit 12.
An output of the receiving unit 12 is supplied to a demodulating unit. l3. The demodulating unit 13 performs, for example, a demodulating process of an FSK (Frequency Shift Keying). Data of a message is demodulated from the reception signal by the demodulating unit 13. The demodulated message data is transmitted to a microcomputer 14.
The microcomputer 14 controls the whole pager 1. An input is supplied to the microcomputer 14 from ' CA 02284289 1999-09-20 the rotary knob 3 comprising a rotary encoder 18 and a switch 19 and an input is also supplied from the escape key 4. An output from the microcomputer 14 is supplied to the display 2 and to an output unit 17. The output unit 17 is, for example, a buzzer or a speaker to inform of a call reception or a vibrator which vibrates upon call reception.
When the pager 1 is called, a message is transmitted from the company of the pager to the pager 1. The message data is, for example, FSK modulated and transmitted by using a radio wave of a frequency band 900 MHz. This signal is sent to the receiving unit 12 through the antenna 11 and message data is demodulated from the signal by the demodulating unit 13. The message data is sent to the microcomputer 14.
When the message data is received, the microcomputer 14 allows the message data to be displayed by the display 2 and sends a signal indicative of the reception of the message data to the output unit 17. Thus, a buzzer sound to notify of the call reception is generated or a vibration to notify of the call reception is generated. The transmitted message is displayed on the display 2.
The transmitted message data can be stored in a memory 15. The stored message data can be displayed on the display 2 by operating the rotary knob 3 or escape key 4 by the user.
That is, Figs. 5A and 5B show a display picture plane of the display 2 when the message is z:eceived. When the message is received, as shown in Fig. 5A, characters of the received message are displayed in the display area 62 of the display 2. A
message number is displayed in the display area 60 of the display 2. When the message further continues, the instruction mark 57 is displayed. When the rotary knob 3 is rotated, the display is scrolled. As shown in Fig. 5B, the subsequent message is displayed. A
message type and a time stamp are displayed at the end of the message.
When the message stored in the memory 15 is read out, as shown in Fig. 6A, the rotary knob 3 is rotated during the standby mode and (PERSONAL MESSAGES) or (INFORMATION SERVICE) is selected. The selected :item is displayed in a highlight state. As a highlight display, surrounded characters, emphasized characters, underline, inverted characters, or the like is considered. When (PERSONAL MESSAGES) or (INFORMATIOP~
SERVICE) is selected, the rotary knob 3 is depressed.
When (PERSONAL MESSAGES) or (INFORMATION
SERVICE) is selected by the rotary knob 3 and the rotary knob 3 is depressed, as shown in Fig. 6B, 18 characters in each message are displayed as a list of the messages. The list of those messages is arranged so that the latest message is displayed at the top stage. Symbols 71 to 74 indicative of "not read", "read", "lock", and the like are added to each message.
The rotary knob 3 is subsequently rotated, thereby selecting a desired message from the list of the messages. The selected message is displayed in the highlight state. When the message is selected, the rotary knob 3 is depressed. When the desired message is selected and the rotary knob 3 is depressed, as shown in Fig. 6C, characters of the selected message are displayed.
When the instruction mark 57 of the downward arrow indication is displayed during the display of the message, the instruction mark 57 shows that messages further continue downward. When the rotary knob 3 is rotated, such a downward message is displayed. When the instruction mark 56 of the upward arrow indication is displayed during the display of the message, this means that messages further continue upward. When the rotary knob 3 is rotated upward, such an upward message is displayed.
After the messages as shown in Fig. 6C were displayed, when the escape key 4 is once depressed, the screen is returned to the picture plane to display the message list shown in Fig. 6B. Another message can be selected on the message list selection picture plane.
When the escape key 4 is depressed twice, the screen is returned to the main menu shown in Fig. 6A.
The pager 1 to which the invention is applied has a memo function. The memo function is a function t=o store the telephone number, characters of the name, and numerals as memos into the memory 15 in Fig. 4.
S The character data has been stored in an ROM 20 in Fig.
4. The character data stored in the ROM 20 comprises, for example, four character groups.
When inputting characters, the characters in one character group are displayed. The user selects a desired character from the characters in the character group by using the rotary knob 3. When the desired character does not exist in the character group, the character group is switched to the next character group.
The switching of the character group can be performed by selecting an arrow mark allocated as a soft key in the character group. When the character group is switched, the characters in the next character group are displayed. The user selects a desired character from the characters in this character group by using the rotary knob 3. When the desired character does not exist in the character group, the character group is switched to the further next character group.
As mentioned above, the switching of the character group can be also performed by selecting an arrow mark allocated as a soft key in the character group. Therefore, characters can be inputted by only ' ' ' CA 02284289 1999-09-20 the operation of the rotary knob 3 without needing to expand keys and buttons to input characters.
That is, when the memo function is used, as shown in Fig. 7A, the rotary knob 3 is rotated during the standby mode, (FUNCTION MENU) is selected, and the rotary knob 3 is depressed. When (FUNCTION MENU) is selected and the rotary knob 3 is depressed; as shown in Fig. 7B, a function menu is displayed. Further, on the picture plane of the function menu, the rotary knob 3 is rotated, (MEMO) is selected, and the rotary knob 3 is depressed. When (MEMO) is selected and the rotary knob 3 is depressed, a memo function picture plane as shown in Fig. 7C is displayed.
The memo function picture plane shown in Fig.
'7C is a selection picture plane in case of newly forming a memo and in case of searching the memo.
In case of newly forming a memo, the rotary knob 3 is rotated, (NEW) is selected, and the rotary knob 3 is depressed. When (NEW) is selected and the rotary knob 3 is depressed, an input picture plane of a memo as shown in Fig. 7D is displayed.
As shown in Fig. 7D, a character input area '71 and a character group area 72 are provided in the input picture plane of (MEMO). The character input area 71 is an area to input and edit the memo. In this example, an area of two lines is assured as a character input area 71. A cursor 73 indicating a character input position is displayed in the character input area 71.
A character group comprising a plurality of characters to select the character to be inputted is displayed in the character group area 72. In this example, as shown in Fig. 8, four character groups 21a to 21d are prepared as a character group 21: The character group 21a is a character group of capital letters of alphabet. The character group 21b is a character group of small letters of alphabet. The character group 21c is a character group of numerals and symbols. The character group 21d is a character group of pictorial symbols.
As shown in Fig. 8, marks 23a and 23b, 24a to 24d, 25, 26, and 27 having special meanings are included in the characters of the character groups 21a to 21d which are displayed in the character group area 72.
The marks 23a and 23b function as soft keys to switch the character group 21 and have shapes of arrows. When the rotary knob 3 is rotated and the mark 23a is selected and the rotary knob 3 is depressed, the character group 21 which is displayed in the character group area 72 is switched in accordance with the order of the character group 21a ~ 21d ~ 21c ~ 21b. When the rotary knob 3 is rotated and the mark 23b is selected and the rotary knob 3 is depressed, the character group 21 is switched in accordance with the order of the character group 21a ~ 21b ~ 21c ~ 21d.
The marks 24a to 24d function as soft keys to move the cursor 73 and have a shape of arrows of front, rear, left, and right. When the rotary knob 3 is rotated and the marks 24a to 24d are selected and the rotary knob 3 is depressed, the cursor 73 in the character input area 71 is moved to the front, rear, left, or right.
The mark 25 functions as a soft key showing a space key. The mark 26 functions as a soft key showing a delete key. The mark 27 functions as a soft key showing an insert key. The mark 28 functions as a soft key showing an enter key.
In case of inputting a character, the rotary knob 3 is rotated and a desired character is selected from the character group displayed in the character group area 72. The selected character is displayed in a highlight state.
That is, in Fig. 4, the rotary encoder 18 and switch 19 are provided in association with the rotary knob 3. The rotary knob 3 is rotated and the rotary encoder 18 rotates in accordance with the rotation of the rotary knob 3. An output of the rotary encoder 18 is supplied to the microcomputer 14. The microcomputer 14 controls an address in the ROM 20 in which the character data has been stored in accordance with the output of the rotary encoder 18, thereby moving a pointer 22 in the character group 21. In this instance, the pointer 22 showing the selected character is moved in accordance with the rotating direction of the rotary knob 3.
For example, when the pointer 22 exists at the position of "G" of the character group 21a, by rotating the rotary knob 3 in a predetermined direction, the pointer 22 is moved in accordance with the order of "G" ~ "H" ~ "I" ~ .... When the rotary knob 3 is rotated in the direction opposite to the predetermined direction, the pointer 22 is moved in accordance with the order of "G" ~ "F" ~ "E" ~ ....
When the character is selected from the character group area 72 by the rotary knob 3 and the rotary knob 3 is depressed, the character is inputted to the position of the cursor 73 in the character input area 71. The cursor 73 is advanced by one. As mentioned above, by rotating the rotary knob 3 and selecting the desired character from the characters in the character group 21 displayed in the character group area 72 and depressing the rotary knob 3, the character is inputted into the character input area 71.
When the user wants to input a character which does not exist in the character group, the mark ~?3a or 23b having the arrow shape is selected. Thus, the character group 21 which is displayed in the ' CA 02284289 1999-09-20 character group area 72 can be switched in accordance with the order of the character group 21a ~ 21d ~ 21c 21b or 21a ~ 21b ~ 21c ~ 21d. By switching the character group and selecting the desired character from the characters displayed in the character group area 72 and depressing the rotary knob 3 in a manner similar to the above, the character is inputted into the character input area 71.
Although the character input has been performed to use the memo function in the foregoing example, it is also possible to leave the characters as a memo and to enable the character data to be transmitted as a message.
For example, in case of transmitting the message recorded in the memory 15, each character of the character data is converted into a code corresponding to each numeral (0 1 2 3 4 5 6 7 8 9 0 #) which is used in the telephone and the character data is generated as a dual tone from a speaker of the output unit 16.
Specifically speaking, after dialing to the transmission destination (partner destination), by making the speaker approach a microphone of the receiver of the telephone, a voice sound of the dual tone generated from the speaker is transmitted to the pager company through the telephone line. The pager ~~ompany multiplexes the transmitted audio signal to the ' ' CA 02284289 1999-09-20 radio wave and transmits it from a transmitting station. Thus, it is received by the pager of the transmission destination and the sent message is displayed on the display.
Although the embodiment has been described with respect to the example in which the invention is applied to the pager, the invention is not limited to :it but can be applied to a cellular phone or a communication terminal having an access function or the like of a network.

'7C is a selection picture plane in case of newly forming a memo and in case of searching the memo.
In case of newly forming a memo, the rotary knob 3 is rotated, (NEW) is selected, and the rotary knob 3 is depressed. When (NEW) is selected and the rotary knob 3 is depressed, an input picture plane of a memo as shown in Fig. 7D is displayed.
As shown in Fig. 7D, a character input area '71 and a character group area 72 are provided in the input picture plane of (MEMO). The character input area 71 is an area to input and edit the memo. In this example, an area of two lines is assured as a character input area 71. A cursor 73 indicating a character input position is displayed in the character input area 71.
A character group comprising a plurality of characters to select the character to be inputted is displayed in the character group area 72. In this example, as shown in Fig. 8, four character groups 21a to 21d are prepared as a character group 21: The character group 21a is a character group of capital letters of alphabet. The character group 21b is a character group of small letters of alphabet. The character group 21c is a character group of numerals and symbols. The character group 21d is a character group of pictorial symbols.
As shown in Fig. 8, marks 23a and 23b, 24a to 24d, 25, 26, and 27 having special meanings are included in the characters of the character groups 21a to 21d which are displayed in the character group area 72.
The marks 23a and 23b function as soft keys to switch the character group 21 and have shapes of arrows. When the rotary knob 3 is rotated and the mark 23a is selected and the rotary knob 3 is depressed, the character group 21 which is displayed in the character group area 72 is switched in accordance with the order of the character group 21a ~ 21d ~ 21c ~ 21b. When the rotary knob 3 is rotated and the mark 23b is selected and the rotary knob 3 is depressed, the character group 21 is switched in accordance with the order of the character group 21a ~ 21b ~ 21c ~ 21d.
The marks 24a to 24d function as soft keys to move the cursor 73 and have a shape of arrows of front, rear, left, and right. When the rotary knob 3 is rotated and the marks 24a to 24d are selected and the rotary knob 3 is depressed, the cursor 73 in the character input area 71 is moved to the front, rear, left, or right.
The mark 25 functions as a soft key showing a space key. The mark 26 functions as a soft key showing a delete key. The mark 27 functions as a soft key showing an insert key. The mark 28 functions as a soft key showing an enter key.
In case of inputting a character, the rotary knob 3 is rotated and a desired character is selected from the character group displayed in the character group area 72. The selected character is displayed in a highlight state.
That is, in Fig. 4, the rotary encoder 18 and switch 19 are provided in association with the rotary knob 3. The rotary knob 3 is rotated and the rotary encoder 18 rotates in accordance with the rotation of the rotary knob 3. An output of the rotary encoder 18 is supplied to the microcomputer 14. The microcomputer 14 controls an address in the ROM 20 in which the character data has been stored in accordance with the output of the rotary encoder 18, thereby moving a pointer 22 in the character group 21. In this instance, the pointer 22 showing the selected character is moved in accordance with the rotating direction of the rotary knob 3.
For example, when the pointer 22 exists at the position of "G" of the character group 21a, by rotating the rotary knob 3 in a predetermined direction, the pointer 22 is moved in accordance with the order of "G" ~ "H" ~ "I" ~ .... When the rotary knob 3 is rotated in the direction opposite to the predetermined direction, the pointer 22 is moved in accordance with the order of "G" ~ "F" ~ "E" ~ ....
When the character is selected from the character group area 72 by the rotary knob 3 and the rotary knob 3 is depressed, the character is inputted to the position of the cursor 73 in the character input area 71. The cursor 73 is advanced by one. As mentioned above, by rotating the rotary knob 3 and selecting the desired character from the characters in the character group 21 displayed in the character group area 72 and depressing the rotary knob 3, the character is inputted into the character input area 71.
When the user wants to input a character which does not exist in the character group, the mark ~?3a or 23b having the arrow shape is selected. Thus, the character group 21 which is displayed in the ' CA 02284289 1999-09-20 character group area 72 can be switched in accordance with the order of the character group 21a ~ 21d ~ 21c 21b or 21a ~ 21b ~ 21c ~ 21d. By switching the character group and selecting the desired character from the characters displayed in the character group area 72 and depressing the rotary knob 3 in a manner similar to the above, the character is inputted into the character input area 71.
Although the character input has been performed to use the memo function in the foregoing example, it is also possible to leave the characters as a memo and to enable the character data to be transmitted as a message.
For example, in case of transmitting the message recorded in the memory 15, each character of the character data is converted into a code corresponding to each numeral (0 1 2 3 4 5 6 7 8 9 0 #) which is used in the telephone and the character data is generated as a dual tone from a speaker of the output unit 16.
Specifically speaking, after dialing to the transmission destination (partner destination), by making the speaker approach a microphone of the receiver of the telephone, a voice sound of the dual tone generated from the speaker is transmitted to the pager company through the telephone line. The pager ~~ompany multiplexes the transmitted audio signal to the ' ' CA 02284289 1999-09-20 radio wave and transmits it from a transmitting station. Thus, it is received by the pager of the transmission destination and the sent message is displayed on the display.
Although the embodiment has been described with respect to the example in which the invention is applied to the pager, the invention is not limited to :it but can be applied to a cellular phone or a communication terminal having an access function or the like of a network.
In the embodiment, although the character group is switched to the previous or subsequent character group by the marks 23a and 23b displayed in the character group 21, one key to switch to only the next character group can be also provided.
In the example, although capital letters and small letters of alphabet, numerals, and special symbols have been used as character groups, other character groups of Katakana, Hiragana, and Kanji (Chinese characters) can be prepared besides those character groups.
According to the invention as described above, the character group 21 is displayed in the character group area 72 of the display 2 and the marks 23a and 23b to switch the character group are displayed as soft keys in the character group 21. Therefore, the marks 23a and 23b are selected from the characters of t=he character group 21 by the rotating operation of the rotary knob comprising the rotary encoder 18 and the character group 21 can be switched by the depressing operation. Thus, the character can be inputted by only the rotary knob 3 without needing to expand the buttons or keys and the operability can be improved.
Industrial Applicability As mentioned above, the portable terminal apparatus according to the invention and the character selection input apparatus and character selection input method which are suitable for use in character input of such a portable terminal apparatus are suitable when they are used for character input of a pager.
