Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to an information terminal and an input control program, such as a cellular phone, etc., equipped with a touch panel for inputting manipulate signals by a pressure of a touch manipulation. 
       BACKGROUND ART 
       [0002]    In recent years, it has been increasing to equip a touch panel for an input manual operation within an information terminal, such as a cellular phone terminal and a portable information terminal (PDA). This type of the touch panel is provided with a touch sensor superposed on a display screen, and the touch sensor detects a contact position and determines whether a user manipulates buttons and icons on the screen by comparing this position and positions of buttons and icons displayed on the screen when the user applies pressure to the display screen with a finger or a pen. 
         [0003]    Incidentally, in accordance with the information terminal as mentioned above, downsizing is expected, but along with rapid progress in multi-functionalization, such as transmission and reception of e-mails, the Internet connectivity, and camera photographing, etc., select options, such as many icons and files, are increasing, and things cannot be displayed on the display screen sometimes. 
         [0004]    As opposed to this, an art disclosed by the patent literature 1 proposes that a user touches a touch panel of a display screen with a finger and moves relative position (up and down or sideways) to scroll option items on the display screen and to move option items that are not displayed on the display screen at first to be displayed on the display screen. According to such arts disclosed in the patent literature 1, it is possible to reduce a number of manipulations by button manipulations etc., to quickly display intended select options, and to select from them.

       SUMMARY OF THE INVENTION 
     Technical Problem 
       [0006]    However, as for the art disclosed in the above mentioned PATENT LITERATURE 1, when one of the many select options displayed on the display screen is selected by the user&#39;s finger through the touch panel, other select options which are adjacent to the intended select option that the user tries to select are accidentally selected since display intervals and display areas of multiple select options are smaller than an area of a user&#39;s fingertip. In particular, when the intended select option that the user tries to select is displayed near a scroll bar, there is a problem that the scroll bar is accidentally selected and the select options disappear from the display screen. 
         [0007]    Therefore, the present invention provides a user interface that can avoid accidentally selecting select options and improve operability within an information terminal, such as a cellular phone and a mobile terminal, having a touch panel, by controlling an input range on the touch panel according to manipulation contents of the user. 
       Solution to Problem 
       [0008]    In order to accomplish the object as described above, the present invention provides an information terminal having a touch panel for inputting manipulate signals with a pressure of a touch manipulation; a manipulate signal acquisition section for detecting a coordinate position of the manipulate signals input to the touch panel; an input range setting section for partitioning multiple input ranges on the touch panel; a manipulate signal analyzing section for acquiring and analyzing a specified manipulate signal; and a manipulate mode switching section for changing a position or size of each of the input range on the touch panel based on a analysis result by the manipulate signal analyzing section. 
         [0009]    In addition, another invention provides an input control program for controlling input of manipulate signals against a touch panel within an information terminal having the touch panel for inputting the manipulate signals with a pressure of a touch manipulation, the input control program causing the information terminal to perform: 
         [0010]    (1) an input range setting step for partitioning multiple input ranges onto the touch panel; 
         [0011]    (2) a manipulate signal acquisition step for detecting a coordinate position of manipulate signals input to the touch panel; 
         [0012]    (3) a manipulate signal analyzing step for acquiring and analyzing specified manipulate signals; and 
         [0013]    (4) a manipulate mode switching step for changing a position or a size of each of the input range on the touch panel based on an analysis result by the manipulate signal acquisition step. 
         [0014]    In accordance with these present inventions, since the input range is partitioned in the touch panel, the input information and the manipulation method can be split according to the partitions, and areas of the touch panel can be effectively utilized. At that time, by manipulating specified manipulation in a partition of either one of the partitions, it is possible to change the input information of each partitions and priority of the manipulation methods by changing locations or areas of the input range, and it is possible to easily change prior input information and manipulation method. 
         [0015]    In the invention as described above, it is preferred that for analyzing the manipulate signals, it measures an input duration at a specified coordinate position; and for switching the manipulate mode, it changes the input range when an input duration measured by measuring the input time becomes a specified duration or an interval. 
         [0016]    In this case, specified manipulate signals can be specified by the specified coordinate position, the input duration and the interval, for example long-pressing an arbitrary point on the touch panel and tapping, etc., and it is possible to implement changing the input information and the manipulation methods easily without providing a special device. 
         [0017]    In the invention as described above, it is preferred that a first input range and a second input range are partitioned for setting the input range;
   the first input range displays selectable select options as icons by touch manipulation and moving the icons according to a shift amount of the coordinate position of the manipulate signals at the first input range;   the second input range displays a total shift amount of the icons as a gauge, and the gauge is changed according to a shift amount of the coordinate position of the manipulate signals in the second input range; and for switching the manipulate mode, it is independent from a display range of the gauge and a display range of the icons, and a position and a size of the first input range and the second input range are changed   
 
         [0020]    In this case, when the first and the second input range have a hierarchical relationship, it is possible to switch a hierarchy by specific switching manipulation. At this time, since the display range of the icons or the gauge are kept intact and a location and an area of the input range are changed independently from the display, malfunctions over the display range can be accepted and manipulations toward any input ranges can be given priority. 
         [0021]    In the invention as described above, it is preferred that for setting the input range, the input range is split into multiple split screens, and the first input range and the second input range are partitioned as a pair within all or a part of the multiple split screens. In this case, it is possible to form multiple manipulate objects on one touch panel at the same time, and it is possible to achieve diversification as an interface. 
         [0022]    In the invention as described above, it is preferred that the icons are arrayed in a spiral form, and shifted back and forth in a radial direction in accordance with a rotational transfer of the coordinate position of an input signal in the first input range or in accordance with a manipulated variable against the gauge in the second input range. 
         [0023]    In this case, necessary information can be intensively presented in a limited display range such that the icons are arranged in a helical form within a virtual space and displayed in a so-called spiral form, which is two-dimensionally indicating them, and the icons are displayed zooming in and out its scaling such that zooming-out from the center to the outward, or zooming-in from the outside to the center by rotating manipulation of the user to form clockwise or counter-clockwise spiral. In particular, in this invention, a rotational manipulation that the user describes a circle with touched finger is manipulated in the first input range, and it is possible to switch shifting method of the icons because of a manipulation to change a gauge display in the second input range such that rotationally shifting the coordinate position of the input signal or sliding a point on the gauge; therefore, it is possible to improve operability. 
         [0024]    In the invention as described above, it is preferred that the select options form a virtual hierarchical structure according to its type, a link is formed between the select options according to a mutual relevance, and it is possible to be shifted between hierarchies by following the link; and the icons are arranged in the spiral form according to the hierarchical structure or the link, and color-coded by hierarchies or coded to be displayed. 
         [0025]    In this case, it is possible to organize with a virtual hierarchical structure when the select options are increased by multi-functionality of the information terminal and wide variety of icons are needed to be displayed, and it is possible to improve operability by presenting this hierarchical structure in the above mentioned spiral form. 
       Advantageous Effects of Invention 
       [0026]    In accordance with the present invention, it is possible to provide a user interface that can avoid accidentally selecting select options and improve operability within an information terminal, such as a cellular phone, etc., by controlling an input range on the touch panel according to manipulation contents of the user.

     DESCRIPTION OF EMBODIMENTS 
       [0037]    With reference to the accompanying drawing, an embodiment of an information terminal related to the present invention is described in detail in the following.  FIG. 1  is an outline view of a portable communication terminal  1  in accordance with this embodiment. As shown in  FIGS. 1(   a ) and ( b ), the portable communication terminal  1  is provided with a body  100  of rectangular shape, and a touch panel  300  is provided in a predetermined arrangement on a surface in a front side of the body  100 . 
         [0038]    (Description for Displaying and Manipulation of Touch Panel) 
         [0039]    The touch panel  300  is an input device inputting manipulate signals with a pressure of a touch manipulation, touching with a finger of a user, a pen or the like, and is provided with and superposed on a LCD  165  which is displaying graphics and a touch sensor  168  which is receiving the manipulate signals corresponding to a coordinate position of the graphics displayed on the LCD  165 . The portable communication terminal  1  of this embodiment is provided with a manual operation button  166 , such as a button switch, an arrow key, and so forth, other than the touch panel  300 , and it is possible to input the manipulate signals by using this manual operation button  166 . 
         [0040]    As shown in  FIGS. 1(   a ) and ( b ), the touch panel  300  displays manipulation menu, select options selectable by a touch manipulation, as icons. The icons are arranged in a spiral form on a display screen which is displayed by the LCD  165 , and the icons are provided to shift according to the touch manipulation. In detail, in accordance with this embodiment, by arranging multiple icons in a helical form within a virtual space and two-dimensionally indicating them, the icons are arrayed in a so-called spiral form. By rotating manipulation of the user toward the touch panel  300  to form clockwise or counter-clockwise spiral, icons are displayed zooming in and out its scaling such that zooming-out from the center to the outward, or zooming-in from the outside to the center. 
         [0041]    In addition, in accordance with the touch panel  300  of this embodiment, as shown in  FIG. 5 , the icons are arranged in the spiral form in a first input range  401 , and a gauge is displayed in a second input range  402 . Generally, the icons are shifted by rotational manipulation (“round-and-round manipulation”) on the first input range, and a present shift amount with respect to a total shift amount of the icons is displayed at a position of a point on the gauge. 
         [0042]    When this round-and-round manipulation is detected, the display range of the icons and the gauge are kept intact, a proportion of the first and the second input range is changed, and entire touch panel  300  is set to the first input range. As a result, although the user touches the gauge during the round-and-round manipulation, the manipulation toward the gauge is ignored and malfunction may be avoided. 
         [0043]    On the other hand, in accordance with either one of the first or the second input range, as shown in  FIG. 5(   b ), when any one point is long pressed for a specified duration, the display range is kept intact, the second input range is zoom out, and the entire touch panel  300  is set to the second input range. This duration for long pressing is memory indication on the gauge, and a sufficient duration for switching the input range is indicated as if energy has been stored in an energy gauge. 
         [0044]    As a result, it is possible to perform manipulations of the gauge at any place on the touch panel, and a point of the gauge is easily manipulated although a display of the gauge is small. In particular, since the duration for switching the input range is indicated at the energy gauge, sufficient duration can be visually verified and malfunctions can be avoided. 
         [0045]    In this way, the first and the second input range can have a hierarchical relationship, and a hierarchy of the input range can easily be switched. At this time, since the display range of the icons or the gauge are kept intact and a location and an area of the input range are changed independently from the display, malfunctions over the display range can be accepted and manipulations toward any input ranges can be given priority. 
         [0046]    Moreover, in accordance with this embodiment, the above mentioned select options, as shown in  FIG. 8(   a ), it forms a virtual hierarchical structure according to its type, a link is formed between the select options according to a mutual relevance, and it is possible to be shifted between hierarchies by following the link. In addition, in accordance with the above mentioned second input range, as shown in  FIGS. 8(   b ) and ( c ), the icons are arranged in the hierarchical structure or linearly arranged according to the link, arrayed in the spiral form, and color-coded by hierarchies ( FIG. 8(   b ) or coded ( FIG. 8(   c )) to be displayed. This color-coding and coding may be performed against all icons displayed on the display, and as shown in  FIG. 9 , it may also be formed to change colors and forms of the focus  403  according to the hierarchy of the icons, alternative options located in the focus  403 . 
         [0047]    Furthermore, when the select options are related to camera functions, this focus indication may be a focus  404  designed like a camera shutter, as shown in  FIG. 10(   a ) through ( d ). In accordance with this focus  404 , as enlarged and shown in  FIG. 10(   e ), settings of a shutter speed, an exposure compensation, and other camera functions are indicated by colors and figures. In addition, as shown in  FIG. 10(   a ) through ( d ), settings according to situations at photographing, such as “portraits camera” suitable for taking indoors and outdoors pictures of people, “birthday camera,” “baby camera,” and etc., or types of subject are indicated by colors of the shutter or changes of the figures so that users may visually perceive camera settings. 
         [0048]    (Internal Configuration of Portable Communication Terminal) 
         [0049]    The following is a detailed explanation for a specific internal configuration of the portable communication terminal  1 , described above, having a displayable and manipulatable touch panel.  FIG. 2  is the block diagram showing the internal configuration of the portable communication terminal  1  related to this embodiment. As shown in the figure, the portable communication terminal  1  is provided with a duplexer  102  connected to an antenna  101 , and the receiving system module and transmission system module which were connected to this duplexer  102 . 
         [0050]    As for the receiving system module, it has a low noise amplifier  110 , a mixer  111 , an IF amplifier  112 , an orthogonal mixer  113 , an A/D converter  114 , a demodulator  115 , a channel decoder  116 , an audio decoder  117 , a D/A converter  118 , an amplifier  119  with a switch and a loudspeaker  120 . On the other hand, as a transmission system module, it has a microphone  140 , an amplifier  139 , an A/D converter  138 , a voice encoder  137 , a channel encoder  136 , a modulator  135 , a D/A converter  134 , an orthogonal mixer  133 , an IF amplifier  132 , a mixer  131 , and a power amplifier  130 . 
         [0051]    The portable communication terminal  1  is provided with a synthesizer  103 , a time base  150 , a CPU  200 , a RAM  152 , a ROM  153 , and an EEPROM  151  as a control system module, is provided with an acceleration sensor  164 , an LCD  165 , a manual operation button  166 , an LED  167 , a touch sensor  168 , and a vibrator  174  as a user interface system module, and is provided with an electrical power system battery  171 , a power supply  172 , and an A/D converter  173  as an electrical power system module. 
         [0052]    The antenna  101  transmits and receives a signal to abase station (not shown) via an 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 . 
         [0053]    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. The 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 the IF amplifier  112 . The A/D converter  114  digitizes the output of the orthogonal mixer  113 . The demodulator  115  restores to the output of the 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 the CPU  200  and voice data is sent out to the audio decoder  117 . 
         [0054]    The signal inputted into the audio decoder  117  from the channel decoder  116  is decoded by voice data, and is delivered to the D/A converter  118 . The D/A converter  118  changes the output of the audio decoder  117  into the analog signal. The amplifier  119  with the switch is changed to suitable timing based on the control signal from the CPU  200 , and amplifies the output of the D/A converter  118  in the state of the switch ON. The loudspeaker  120  amplifies the output of the amplifier  119  with the switch. 
         [0055]    On the other hand, in the transmission system module, the microphone  140  receives the audio signal from the user, and outputs this audio signal as an analog signal. The amplifier  139  amplifies the analog signal outputted from the microphone  140 . The A/D converter  138  changes the output of the amplifier  139  into the digital signal. The voice encoder  137  codes and curtails the output of the A/D converter  138 , and outputs it as voice data. The channel encoder  136  combines the control message from CPU  200  with a voice data from the voice encoder  137  and adds the error correcting code. 
         [0056]    In addition, the modulator  135  modulates the output of the channel encoder  136 . The D/A converter  134  changes the output of the modulator  135  into an analog signal. The orthogonal mixer  133  changes the output of the D/A converter  134  into the IF frequency signal (intermediate frequency signal). The IF amplifier  132  amplifies the output of the orthogonal mixer  133 . The mixer  131  raises the frequency of the signal which IF amplifier  132  outputs. The power amplifier  130  amplifies the output of the mixer  131 . 
         [0057]    The synthesizer  103  takes the synchronization of the mixer  111 , the orthogonal mixer  113 , the mixer  131 , and the orthogonal mixer  133  during communication. The time base  150  supplies the clock signal to each part. 
         [0058]    In the user interface system, the acceleration sensor  164  is the sensor which detects a value and a direction of acceleration. The LCD  165  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 , graphics, such as characters, figures and videos (movies), can be displayed via this LCD  165 , and the manipulate signal is acquired through the touch sensor  168  on the touch panel  300 . 
         [0059]    The LED  167  is for telling the user the message by lighting and putting out lights. The touch sensor  168  detects that the user&#39;s finger contacted the touch panel surface, and inputs the manipulate signal with a pressure to the touch panel  300  surface. The vibrator  174  is a device which informs mail arrival, and when it receives a message, it will vibrate. 
         [0060]    The electrical power system battery  171  supplies electric power to the power supply  172  and the A/D converter  173 . The power supply  172  is a power supply of the portable communication terminal  1 . The A/D converter  173  supplies a signal to the CPU  200 . 
         [0061]    The CPU  200  is an processing unit which controls each section of the above, carries out sequential execution of the command of the program stored in ROM  153 , and performs the various functions. The RAM  152  is used as a working memory of the CPU  200 , etc. and stores the result of an operation by the CPU  200  temporarily. The program for the CPU  200  is recorded on the ROM  153  and the executive instruction of the program is outputted one by one with the request from the CPU  200 . The user data, IDs indigenous on the body, and the telephone numbers, such as the abbreviated dialing, are recorded on the EEPROM  151 . 
         [0062]    In addition, as for this embodiment, the CPU  200  works as an application execution section  200   b  to execute applications, and various modules are virtually built on the CPU  200  by executing software, such as the input control program of the present invention, in this application execution section  200   b.    
         [0063]    Concretely, as shown in  FIG. 3 , by executing an application including an input control program of the present invention in an application execution section  200   b,  modules, such as a display information generating section  200   a,  a manipulate signal acquisition section  200   f,  an input range setting section  200   d,  a manipulate signal analyzing section  200   h  and a manipulate mode switching section  200   g  are virtually built. Here, the “module” in the following explanation is constituted by hardware, such as a device and an apparatus, software with a function, or such combination, and indicates the functional unit for attaining predetermined operation. 
         [0064]    An input interface (I/F)  200   e  is a module for receiving manipulate signals of the user input from the touch sensor  168 , the manual operation button  166  and other manipulating devices and inputting to the manipulate signal acquisition section  200   f.    
         [0065]    The manipulate signal acquisition section  200   f  is a module which inputs the inputted manipulate signal into the application execution section  200   b  as an operating command. In detail, an input range setting determined by the input range setting section  200   d  and a relative position of the manipulate signal are compared, and an operating command associated with a comparison result and the manipulate signal is selected and input to the application execution section  200   b.    
         [0066]    Then, in accordance with this embodiment, the manipulate signal acquisition section  200   f  includes the manipulation position detector  200   c.  The manipulation position detector  200   c  is a module for detecting the coordinate position of the manipulate signals input to the touch panel  300 . This coordinate point detects a coordinate point of the input position from an input coordinate position of the manipulate signals detected by the touch sensor  168 . 
         [0067]    The input range setting section  200   d  is a module for partitioning the input range of the manipulate signals on the touch panel  300 . Within this embodiment, the manipulation position detector  200   c  detects a manipulated point (the coordinate position) on the touch panel  300 , and the input range varies according to this detected manipulated point, other input devices, and acceleration detected by the acceleration sensor  164 . 
         [0068]    In detail, the input range setting section  200   d  partitions multiple input ranges  400  on the touch panel  300 , and a first input range  401  and a second input range  402  are partitioned in accordance with this embodiment. At this point, the first input range  401  is an input range for displaying selectable select options by the touch manipulation as icons, and the second input range  402  is an input range for displaying a total shift amount of the icons as a gauge. Then, each of the input range detects the manipulated point on the touch panel  300  by using the manipulation position detector  200   c,  and the input ranges  400  are varied according to this detected manipulated point and the detected acceleration sensor  164 . 
         [0069]    In detail, within the first input range  401 , it is possible to vary its displaying form, such that the icons are arranged in a spiral form as shown in  FIG. 5(   a ), or this spiral form is arranged linearly as shown in  FIG. 5(   b ), and arrangement of the icons can be scrolled by moving the manipulated point to a direction of the icons at each of the displaying form. 
         [0070]    On the other hand, the gauge is displayed at the second input range  402 , and icons displayed at the first input range  401  can be shifted by shifting a point on the gauge according to a scrolling manipulation for sliding a meter of this gauge. That is, this gauge shows the total shift amount of the icons as a length of the gauge, and the gauge and the icons can be interlocked that by shifting a point on this gauge, proportions, in which its point position indicates, to a full length of the gauge become proportions of a present shift amount to the total shift amount of the icons. Herewith, many icons can be scrolled by a little manipulation toward the gauge. 
         [0071]    Furthermore, this input range can switch its display direction by inclination of a main body of the device detected by the acceleration sensor  164  mentioned above. Specifically, as shown in  FIG. 6(   a ) and  FIG. 6(   b ), the display screen automatically turns sideways when the main body of the device is horizontally inclined. In this condition of inclining sideways, as shown in  FIG. 6 , an icon representation of the first input range and a gauge representation of the second input range are displayed as a set, the second input range is enlarged by specified manipulations such as long pressing of the display as shown in  FIG. 6(   a ), and the gauge manipulation can be possible on the display ranges of the icons as shown in  FIG. 6(   b ). 
         [0072]    In addition, the input range setting section  200   d,  as shown in  FIG. 7 , partitions the input range into multiple split screens and includes a function for partitioning the first input range  401  and the second input range  402  as a pair at all or a part of the multiple split screens. As a result, since a combination of the icons and the gauge are many displayed within the screen, multiple interfaces corresponding to wide variety of applications can be provided at the same time for assigning respective input information and manipulation methods to each combinations. 
         [0073]    The manipulate signal analyzing section  200   h  is a module for acquiring and analyzing specified manipulate signals from the manipulate signal acquisition section  200   f  and for transmitting analyzed signals to the application execution section  200   b  and the manipulate mode switching section  200   g,  and includes an input time measuring section  200   i  and a shift amount computing section  200   j  in accordance with this embodiment. 
         [0074]    The input time measuring section  200   i  is a module for measuring an input duration at a specified coordinate position, and the shift amount computing section  200   j  is a module for calculating a shift amount of the coordinate position of the manipulate signals generated by the touch manipulation. 
         [0075]    The manipulate mode switching section  200   g  is a module for changing a position or a size of each input range on the touch panel  300  based on a analysis result by the manipulate signal analyzing section  200   h,  and in accordance with this embodiment, the input range is changed when the input duration, measured by the input time measuring section  200   i,  becomes a specified duration or an interval. 
         [0076]    In addition, the manipulate mode switching section  200   g,  which is independent from the display range of the icons and the display range of the gauge, provides functions to change positions and sizes of the first input range  401  and the second input range  402 . 
         [0077]    The display information generating section  200   a  is a module for generating display information (graphics and textual information) displayed on the LCD  165 , and configures GUI by cooperating with the manipulate signal acquisition section  200   f.  This display information generating section  200   a  provides functions for setting a range to display the display information on the LCD  165  and partitioning the display range at the LCD  165  in to multiple display ranges. In addition, ratio of multiple display range is varied according to a relative position detected by the manipulation position detector  200   c.    
         [0078]    Moreover, in accordance with this embodiment, the display information generating section  200   a  displays the first input range  401  and the second input range  402  as input ranges. In the first input range  401 , select options selectable by the touch manipulation are displayed as icons. On the other hand, in the second input range  402 , the total shift amount of the icons is displayed as a gauge. 
         [0079]    Furthermore, the input range setting section  200   d  splits the input range into multiple split screens, and also provides a function for partitioning the first input range  401  and the second input range  402  as a pair within all or a part of the multiple split screens. 
         [0080]    In addition, the display information generating section  200   a  also provides a function for changing the display information according to the coordinate point (a relative position at the touch panel  300 ), which is detected by the manipulation position detector  200   c  and input the manipulate signals, and the acceleration, which is detected by the acceleration sensor  164 . 
         [0081]    The application execution section  200   b  is a module for executing the program and builds each above module virtually on the CPU  200 . In particular, in accordance with this embodiment, it controls to shift icons according to a shift amount of the coordinate position of the manipulate signals in the first input range  401  based on an input from the manipulate signal acquisition section  200   f  and the manipulate signal analyzing section  200   h;  meanwhile, m it controls to change the gauge according to the shift amount of the coordinate position of the manipulate signals in the second input range  402 . Specifically, as shown in  FIG. 1 , it controls to shift back and forth in a radial direction according to a rotational transfer of the coordinate position of an input signal in the first input range  401  or a manipulated variable toward the gauge in the second input range  402 . 
         [0082]    (Manipulation of Interface and Controlling Method) 
         [0083]    By executing the program above mentioned, manipulation of the interface and controlling method can be performed.  FIG. 4  is a flowchart illustrating manipulating method of the portable communication terminal  1  of this embodiment. 
         [0084]    The portable communication terminal  1  is provided with many features such as transmission and reception of e-mails, the Internet connectivity, camera photographing, a video or picture browser and games, and following is an explanation of an example of manipulation when the user selects either one of each feature through the touch panel  300 . 
         [0085]    In addition, the input range of the touch panel  300  includes the first input range  401  and the second input range  402  in advance. 
         [0086]    First, the user inputs against the touch panel  300  by using a finger or a pen point, and these input manipulate signals are input to the manipulate signal acquisition section  200   f  through the input interface (I/F)  200   e  and detected as manipulate signals (S 101 ). Then, the manipulation position detector  200   c  detects the coordinate position of the manipulate signals input to the touch panel  300  from this manipulate signals (S 102 ). At this point, the manipulation position detector  200   c  determines from the coordinate position whether the input range is the first input range or the second input range. Furthermore, the manipulate signal acquisition section  200   f  transmits acquired manipulate signals to the manipulate signal analyzing section  200   h.    
         [0087]    The manipulate signals received from the manipulate signal acquisition section  200   f  is input to the input time measuring section  200   i,  and the input time measuring section  200   i  measures the input duration in the specified coordinate position (S 103 ). At this point, when the input duration is in a certain period of time (“N” in S 104 ), a manipulation mode is unswitched (S 105 ), and a presence or absence of a manipulation input is determined without changing areas of the first input range  401  and the second input range  402  (S 108 ). 
         [0088]    When the manipulation input is absent (“N” in S 108 ), the process is on standby until next manipulation input is operated and the manipulation signals are detected. When the manipulation input is present (“Y” in S 108 ), a process is executed according to manipulation contents, such as a manipulation location of its manipulation input and a shift amount, and the display information generating section  200   a  generates and changes display information, such as moving icons and displaying applications (S 110 ). 
         [0089]    On the other hand, when the input duration is greater than a certain period of time (“Y” in S 104 ), the manipulate mode switching section  200   g  changes to the manipulation mode (S 106 ) and changes all of the input ranges to the second input range (S 107 ). Then, the application execution section  200   b  determines presence or absence of input of the manipulate signals (manipulation input) (S 108 ). 
         [0090]    At this point, when the manipulation input is absent (“N” in S 108 ), the process is on standby until next manipulation input is operated and the manipulation signals are detected. When the manipulation input is present (“Y” in S 108 ), a process is executed according to manipulation contents, such as a manipulation location of its manipulation input and a shift amount. Since the manipulation mode is changed, all of the input ranges  400  are the second input range  402  now, and the manipulation contents based on the second input range is executed when either location is manipulated (S 109 ). Then, the display information generating section  200   a  generates and changes the display information, such as quickly moving icons (S 110 ). 
         [0091]    (The Operation and Effects) 
         [0092]    According to the present embodiment explained above, since the input range is partitioned in the touch panel, the input information and the manipulation method can be partitioned according to the partitions, and the areas of the touch panel can be effectively utilized. At that time, by long pressing in the partitions of either the first input range  401  or the second input range  402 , it is possible to change locations or areas of the input range, enlarges the input range of one side, and the input information and the manipulation method toward enlarged ranges can be given priority. 
         [0093]    As a result, according to the present embodiment, within an information terminal, such as a cellular phone etc., an input range of a touch panel  300  can be controlled according to manipulation contents of a user, an erroneous selection of select options by the touch manipulation can be avoided, and operability can be improved.
