The antenna 101 transmits and receives the signal to the base station (not shown) via the electric wave line. The duplexer 102 is a circuit which changes input and output of the signal transmitted and received, inputs into the low noise amplifier 110 the signal which the antenna 101 received, and outputs the signal outputted from the power amplifier 130 to the antenna 101.

In the receiving system module, the low noise amplifier 110 amplifies the signal inputted from the duplexer 102, and outputs it to the mixer 111. The mixer 111 undergoes the output of the low noise amplifier 110, separates only specific frequency, and is outputted as an intermediate frequency signal. IF amplifier 112 amplifies the intermediate frequency signal outputted from the mixer 111. The orthogonal mixer 113 undergoes and carries out orthogonal demodulation of the output of IF amplifier 112. The A/D converter 114 digitizes the output of the orthogonal mixer 113. The demodulator 115 restores to the output of A/D converter 114. The channel decoder 116 carries error correction to the output of the demodulator 115. The control message and voice data are contained in the signal which carried error correction. The control message is sent out to CPU160 and voice data is sent out to the audio decoder 117.

The signal inputted into the audio decoder 117 from the channel decoder 116 is decoded by voice data, and is delivered to D/A converter 118.

In the user interface system, the acceleration sensor 164 is the sensor which detects the value and the direction of acceleration. The LCD165 is a liquid crystal display on which the user is made to display the message, the input character, etc. In GUI on the touch panel 300, the key for inputting the numbers from “0” to “9”, “#”, etc. via this LCD165 can be displayed, and the manipulate signal is acquired through the touch sensor 168 on the touch panel 300.

The gadget section 200 is the input device formed in the longitudinal direction of the surface of the body so that slide movement was available, and equips the front face part with the manual operation button 201,202 and the arrow key (joystick) 203.

The LED167 is for telling the user the message by lighting and putting out lights. The touch sensor 168 detects that the user's finger contacted the touch panel surface, and inputs the manipulate signal with the pressure to the touch panel 300 surface. It may be made for the touch sensor 168 to detect the user's fingerprint. The vibrator 174 is a device which informs mail arrival, and when it receives a message, it will vibrate.

The electrical power system battery 171 supplies electric power to the power supply 172 and A/D converter 173. The power supply 172 is the power supply of the portable communication terminal 1. The A/D converter 173 supplies the signal to CPU160.

The CPU160 is an processing unit which controls each section of the above, carries out sequential execution of the command of the program stored in ROM163, and performs the various functions. The RAM162 is used as a working memory of CPU160, etc. and stores the result of an operation by CPU160 temporarily. The program for CPU160 is recorded on ROM163 and the executive instruction of the program is outputted one by one with the request from the CPU160. The user data, IDs indigenous on the body, and the telephone numbers, such as the abbreviated dialing, are recorded on the EEPROM161.

And as for this embodiment, modules, such as a display information generating section 160a, a manipulation position detector 160c, and an input range setting section 160d, are virtually built by CPU160 by executing the above program by the application execution section 160b as shown in FIG. 3. Here, the “module” in the following explanation is constituted by hardwares, such as the device and apparatus, software with the function, or such combination, and means the functional unit for attaining predetermined operation.

The application execution section 160b is a module for executing the program and builds each above module virtually on the CPU160.

The display information generating section 160a is a module for generating the display information, including the picture, alphabetic information, etc., displayed on the LCD165, and constituting GUI by cooperating with the manipulate signal acquisition section 160f. This display information generating section 160a is provided with the function to divide the display range in the LCD165 into a plurality of display ranges while it sets up the range which displays display information on the LCD165. And the ratio of a plurality of display ranges is changed with the relative position detected by the manipulation position detector 160c.

The display information generating section 160a changes display information according to the coordinate point (the relative position on the touch panel 300) which the manipulate signal was inputted and was detected by the manipulation position detector 160c, and the acceleration detected by the acceleration sensor 164.

The manipulation position detector 160c is a module for detecting the coordinate point specified on the touch panel 300. This coordinate point is detected as a coordinate point of the input position based on the input coordinate of the manipulate signal which the touch sensor 168 detected, and the relative position of the gadget section 200 on the body. The display information generating section 160a changes display information according to the relative position of the gadget section 200 on the body detected by this manipulation position detector 160c.

The input range setting section 160d is a module for dividing the input range of the manipulate signal on the touch panel 300. In the case of the present embodiment, the manipulation position detector 160c detects the operating point on the touch panel 300, and the relative position of the gadget section 200, The input range changes according to this detected relative position and the acceleration which the acceleration sensor 164 detected. The input interface (I/F) 160e is a module which receives the user's manipulate signal inputted from the operation devices, such as the touch panel, the manual operation button, the joystick, and is inputted into the manipulate signal acquisition section 160f.

The manipulate signal acquisition section 160f is a module which inputs the inputted manipulate signal into the application execution section 160b as an operating command. In detail, the manipulate signal is compared with the relative position of the gadget section 200, and the input setting for which the input range setting section 160d determines, the operating command associated with the comparison result and manipulate signal is selected, and is inputted into the application execution section 160b.

Operation Method

The portable communication terminal 1 which has the above composition is operated as follows. The portable communication terminal 1 is provided with many functions, such as transmission and reception of e-mail, the Internet connectivity, camera photographing, the movie/picture browser, the game, as to the touch panel 300 or the gadget section 200, the manipulate signal and operating command which are assigned to each manual operation button (GUI is included.) are suitably changed according to the input mode in each function.

For example, as shown in FIG. 4, in cases where the touch panel 300 is divided into the above and below display ranges 301 and 302 by making the gadget section 200 into the boundary line, the ratio of the display ranges 301 and 302 changes by sliding the gadget section 200 up and down, and changing the relative position to the body 100. At this time, as shown in the FIG. (b) and (c), the character input key 401 is displayed on the lower display range 302 as GUI as an input range responded the input mode, the display range is expanded and contracted by the slide moving of the gadget section 200.

In addition, in the case of the present embodiment, the auxiliary input key 402 is added and displayed with the character input key 401 by the further upward movement of the gadget section 200. As for this auxiliary input key 402, the character group forecast from the character inputted by the character input key 401 is displayed. In the illustrated example, in cases where Japanese “A” is inputted by the character input key 401, the character group forecast from “A” is displayed. In this way, the above manipulate signal acquisition section 160f changes the coordinates of the input range of each input key according to the expanding and contracting of the input range, and the addition and reduction of the input key, and compares the operating point and the input range of each input key which are inputted by the user's touch operation, and selects the inputted operating command.

As shown in FIG. 5, regarding the input key, the character kind to input is automatically changed according to the input mode of each application. For example, be shown in the figure (a), in the case of calling operation, when alter operation is carried out, the number like the telephone number will be inputted, as shown in the FIG. (b) and (c), in inputting the texts, such as e-mail, it changes to katakana, the hiragana, and Roman letters input, as shown in the figure (d), in the input columns (text box), such as the mail address, the input of the half-width alphabetic characters and the symbols are available. In the figure (e), in cases where it starts application and the function, the menu item is displayed on the input key.

As shown in FIG. 6 (a), in list display modes, such as the address book, it becomes the complete display by lowering the gadget below, at this time, address information can be called by touching the name listed in the list.

As shown in FIG. 6 (b), in cases where the portable communication terminal 1 is used as a game controller, the input range is divided according to the relative position of the gadget section 200 detected by the position detector, and the gadget section 200 and the input range 403 are positioned in the both sides of the display range 301 of display information. Thereby, when the game screen is displayed on the display range 301, the joystick of the gadget as an arrow key and the manual operation button displayed on the input range 403 are placed at the both sides. The position of the gadget section 200 can turn over right and left by slide moving, and the input range 403 can also be positioned in the opposite side of the game screen following it.

As shown in FIG. 7 (a) and (b), at the input range 404, the input key of GUI is placed obliquely the 45 degrees, by detecting tilt of the body with the acceleration sensor, the character to display may be changed corresponding to it. That is, each of the input key displayed cancellous as GUI is tilted the 45 degrees, when the body is stood or lie down, the character is arranged in each readable direction. In cases where it stands, as for these characters, the character in the input key becomes the input character, when it lies, the character besides the input key becomes the input character. In this case, even though the two characters will be assigned to the one input key, the character inputted is switched in the time of lying with the time of standing corresponding to the detection result of the acceleration sensor.

As shown in the figure (b), the left screen 405 is the menu screen of the card game type in the case of the present embodiment. In the menu screen of this card game type, the application and the function for starting are assigned to the card shape icon (card icon) I1 like playing card, and each function can be started by touching this card icon I1. As to this card icon I1, the card icon is shuffled by shaking the body and generating acceleration, the position of the card icon and the overlap can be changed, thereby, the card icon assigned the required function can be moved to the position easy to operate. The box type icon (box icon) I2 is displayed together, and by touching this box icon I2, the card can be aligned or can be put into the box icon I2. By shaking the body, in the screen, this box icon I2 itself can also roll and can be moved.

Modification Example

Incidentally, the present invention is not limited thereto, but it is possible to add a variety of modification. For example, With the above embodiment, even though modification of the display range and the input range is adjusted by slide moving of the gadget section 200, FIG. 8 (a) be shown in—(d), the coordinate point on the touch panel 300 is appointed by touching and dragging the basic information bar 303 as a boundary line with the finger 300a, the ratio of the display range 301,302 may be changed by making this move up and down.

Operation/Effect

In accordance with the present embodiment, since the screen is divided into a plurality of display ranges 301, or 302 and the input range 400, the information displayed on the touch panel can be made clear, and the display mode can be varied according to each function of the information terminal, and it is possible to respond to multi-functionalization of the information terminal.

Particularly, in the case of the present embodiment, since the coordinate point on the touch panel 300 can be specified with the position of the gadget section 200 slid to the longitudinal direction of the body 100 surface, by moving the gadget section 200, the boundary line at the time of dividing into a plurality of display ranges can be changed freely, thereby, the area of each display range can be expanded and contracted.

Further, in the case of the present embodiment, since to have further the acceleration sensor 164 for detecting value and the direction of acceleration given to the body 100, the display style can be changed with acceleration given to the body 100 by shaking, tilting, standing or laying in addition to alter operation on the input interface like the gadget section 200 and the touch panel 300.

In addition, as shown in FIG. 7 (a) and (b), the display mode of the display button can be settled without being affected by effect of the direction of the body, since to make the input key of GUI tilt over the 45 degrees, to detect the direction of the body with the acceleration sensor as the input range 404 and to change the character displayed, since the manipulate signal inputted changes responding the direction of the body, the user can carry suitable alter operation by pushing the input key according to the character of the direction easy to read, without being sensible of the direction of the body.

Since the manual operation buttons 201 and 202 and the arrow key 203 are placed as an input part for inputting the manipulate signal into the gadget section 200, the manipulate signal can be inputted also from gadget section 200 itself, and diversification of the interface can be attained. In addition, as shown in FIG. 6, since the input range is divided in order that the gadget section 200 and the manual operation button 403 may be positioned in both sides of the display range 301, the manual operation button and the arrow key can be arranged on both sides of the game screen (display range 301), for example like the game controller.
