Description

  The present invention relates to a mobile terminal, an information processing method, and a program.

  In recent years, portable terminals such as tablet terminals, smartphones, and handy terminals have been used for various tasks in various situations.

  In many portable terminals, the display screen portion is a touch panel, and the operation / instruction by the user is received by directly pressing a button displayed on the screen.

  As described above, since the portable terminal is used in various places, settings that are easy to operate differ depending on the environment of the place where the portable terminal is used.

  Japanese Patent Application Laid-Open No. 2004-228688 describes a technique for providing a user interface that is easy to visually recognize by changing the size of a button displayed on a touch panel depending on the illuminance at a place where the device is used.

JP 2001-197185 A

  As described above, the portable terminal is used in various places, for example, in a cold district or a freezer warehouse. Thus, when used in a place where the temperature is low, it is considered that the user operates the mobile terminal with thick gloves.

  When operating with thick gloves, the contact area between the fingertip and the touch panel increases, and it is difficult to check the contact position, so the user presses a button that is different from the button that the user tried to press. This is likely to cause erroneous operations.

  In addition, when the touch panel is operated in a state of shaking on the sea such as on a ship, an incorrect button may be pressed in the case of a small button.

  Further, if the button area is small in the above-described case, even if the button area is intended to be pressed, an area where the pressing cannot be detected (area that is not a button) may be pressed.

  As described above, for example, in the case of an operation with a glove, an operation with a biting hand, an operation on a swaying ship, etc., fine work becomes difficult, and the possibility of an erroneous operation increases.

  Therefore, an object of the present invention is to provide a mechanism for reducing erroneous operations even in a situation where fine work is difficult, such as when used in a place where the temperature is low.

  The present invention is a portable terminal that receives an instruction from a user by pressing an instruction reception area in the display unit, and an acquisition unit that acquires an external state, and an external state acquired by the acquisition unit are: And a control means for changing the instruction receiving area when a predetermined condition is satisfied.

  The present invention is also an information processing method in a mobile terminal that receives an instruction from a user by pressing an instruction receiving area in the display unit, wherein the acquisition unit of the mobile terminal acquires an external state And a control step of changing the instruction receiving area when the external state acquired by the acquisition step satisfies a predetermined condition.

  In addition, the present invention is a program that can be executed in a mobile terminal that receives an instruction from a user when an instruction receiving area in the display unit is pressed, and the mobile terminal acquires an external state. When the external state acquired by the acquisition unit satisfies a predetermined condition, the external unit is made to function as a control unit that changes the instruction receiving area.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the structure which reduces an erroneous operation also in the situation where detailed work is difficult, such as the case where it uses at the place where temperature is low.

  The control unit 152 has a function of expanding the instruction reception area in the display unit 154 when the temperature acquired by the acquisition unit 151 satisfies a preset condition. In addition, a function for enlarging buttons displayed on the display unit 154 in accordance with enlargement of the instruction receiving area is provided.

  The determination unit 153 has a function of determining whether an instruction via the touch panel by the user is using a touch pen or a user's finger.

  The display unit 154 is a touch panel, and has a function of receiving an instruction to the mobile terminal when the instruction receiving area of the touch panel is pressed (contacted) by the user. Further, the display unit has a function of displaying an instruction receiving area for detecting a press by the user as a button. It also has a function to display other necessary information.

  Next, the hardware configuration of the mobile terminal 101 according to the present invention will be described with reference to FIG.

  In FIG. 2, reference numeral 201 denotes a CPU that comprehensively controls each device and controller connected to the system bus 204. Further, the ROM 203 or the external memory 211 is necessary to realize a BIOS (Basic Input / Output System) or an operating system program (hereinafter referred to as an OS), which is a control program of the CPU 201, or a function executed by each server or each PC. Various programs are stored.

  A RAM 202 functions as a main memory, work area, and the like for the CPU 201. The CPU 201 implements various operations by loading a program necessary for execution of processing from the ROM 203 or the external memory 211 into the RAM 202 and executing the loaded program.

  An input controller 205 controls input from the input device 209 or the like. A video controller 206 controls display on a display device 210 such as a liquid crystal display. The display device is not limited to a liquid crystal display, and may be a CRT display or the like. These are used by clients as needed.

  A memory controller 207 is connected to the hard disk (HD), flexible disk (FD), or PCMCIA card slot for storing a boot program, various applications, font data, user files, editing files, various data, etc. via an adapter. The access to the external memory 211 such as a compact flash (registered trademark) memory is controlled.

  A communication I / F controller 208 connects and communicates with an external device via a network (for example, the LAN 400 shown in FIG. 1), and executes communication control processing in the network. For example, communication using TCP / IP is possible.

  Note that the CPU 201 enables display on the display device 210 by executing outline font rasterization processing on a display information area in the RAM 202, for example. Further, the CPU 201 enables a user instruction with a mouse cursor (not shown) on the display device 210.

  Various programs that operate on the hardware are recorded in the external memory 211 and are executed by the CPU 201 by being loaded into the RAM 202 as necessary.

  The printer controller 212 controls a printing machine such as a thermal dot line type printer 213.

  The scanner controller 214 controls a discriminator such as the scanner 215.

  It should be noted that not all devices have these configurations, and it is only necessary to provide necessary devices.

  Next, the mode switching process in the embodiment of the present invention will be described with reference to FIG.

  Note that the process illustrated in FIG. 3 is a process in which the CPU 201 of the mobile terminal 101 reads and executes a predetermined control program. The process shown in FIG. 3 is a process that is repeatedly executed at predetermined intervals, for example, every 10 seconds.

  In step S301, the CPU 201 of the mobile terminal 101 acquires whether the most recent operation (operation via the touch panel) is a finger or a so-called touch pen.

  That is, it is determined whether the user has pressed a button displayed on the touch panel with his / her finger or a button displayed on the touch panel using a touch pen.

  Since it is necessary for the processing in this step, the CPU 201 of the mobile terminal 101 determines whether the operation is performed with a finger or a touch pen each time an operation through the touch panel is received.

  If the operation is a touch pen operation (step S303: YES), the process proceeds to step S308. Details of the processing in step S308 will be described with reference to FIG.

  If it is not an operation with a touch pen (that is, an operation with a finger) (step S303: NO), the process proceeds to step S304.

  Whether it is an operation with a touch pen or an operation with a finger can be determined based on the contact area on the touch panel when a button press is detected, pressure, or the like. For example, if the contact area is a predetermined value (for example, a diameter of 2 mm) or less, it is determined as a touch pen, and if it is more than that, it can be determined as a finger.

  In step S304, the CPU 201 of the mobile terminal 101 acquires the outside air temperature. In this embodiment, it is assumed that the thermometer function is attached to the portable terminal 101, and the outside air temperature measured by the thermometer function is acquired. However, it is not always necessary to have the thermometer function. For example, the current location information may be acquired or calculated from a GPS function or a base station of the mobile terminal, and communicated with a server that holds the temperature around the current location to acquire the current temperature.

  Further, as another embodiment, if it is outdoor in the winter from the current position information, it may be in the low temperature mode described below, and if it is determined from the current position information that it is on the sea, it is low. It is good also as temperature mode. A condition for shifting to the low temperature mode described below from the current position information calculated by the mobile terminal will be described with reference to FIG.

  FIG. 13 is a diagram showing an example of data storing position information for shifting to the low temperature mode of the present invention.

  Reference numerals 1301 and 1302 in FIG. 13 denote latitude and longitude of the position information, and an example is shown in which an area having two points 1301 and 1302 as diagonal lines functions as a mode described in 1303. Information associating these position information and mode information may be held by a portable terminal, or may be held by a communicable server.

  As another embodiment, the gyro sensor of the portable terminal shifts to the low temperature mode by determining when the shaking frequency of the portable terminal is 1.2 Hz or less, which is a shaking when riding on a ship. May be. Returning to the flowchart of FIG.

  In step S305, the CPU 201 of the mobile terminal 101 determines whether the outside air temperature acquired in step S304 is equal to or higher than a predetermined temperature. In addition to determining whether the temperature is higher than a predetermined temperature, it may be determined based on the current location information described above whether a predetermined position (outdoor in the sea or winter in Hokkaido) is met. This criterion may be set in advance by the user.

  When judging based on the outside air temperature, the air temperature serving as a judgment criterion is set via the screen shown in FIG. In the example shown in FIG. 9, 3.0 ° C. is the threshold, and if it is 3.0 ° C. or higher, YES is determined in step S305, and if it is less than 3.0 ° C., NO is determined in step S305.

  If the temperature is equal to or higher than the predetermined temperature (step S305: YES), that is, if it can be operated with bare hands, the process proceeds to step S307. Details of the processing in step S307 will be described with reference to FIG.

  When the temperature is lower than the predetermined temperature (step S305: NO), that is, in the case of the low temperature mode, the process proceeds to step S306. Details of the processing in step S306 will be described with reference to FIG.

  Hereinafter, detailed processing in steps S306, S307, and S308 will be described with reference to FIGS.

  FIG. 4 is a flowchart showing the detailed process of step S306.

  In step S401, the CPU 201 of the mobile terminal 101 displays a confirmation screen shown as an example in FIG.

  On the confirmation screen, information for switching to the low temperature mode and buttons for accepting selection of whether to approve the switching (an OK button 801 and a cancel button 802) are displayed.

  In step S402, the CPU 201 of the portable terminal 101 determines whether or not an instruction to approve switching to the low temperature mode is given on the screen shown in FIG. Specifically, in the example of FIG. 8A, the determination is made based on whether the OK button 801 is pressed or the cancel button 802 is pressed.

  If the OK button 801 is pressed (step S402: YES), the process proceeds to step S403.

  When the cancel button 802 is pressed (step S402: NO), the processing shown in this flowchart is terminated.

  In step S403, the CPU 201 of the mobile terminal 101 switches to the low temperature mode.

  Next, detailed processing in steps S307 and S308 will be described with reference to FIG.

  In step S501, the CPU 201 of the mobile terminal 101 displays a confirmation screen as an example shown in FIG.

  On the confirmation screen, information for switching to the normal mode and buttons for accepting selection of whether to approve the switching (an OK button 803 and a cancel button 804) are displayed.

  In step S502, the CPU 201 of the portable terminal 101 determines whether or not an instruction to approve switching to the normal mode is given on the screen shown in FIG. 8B. Specifically, in the example of FIG. 8B, the determination is made based on whether the OK button 803 is pressed or the cancel button 804 is pressed.

  If the OK button 803 is pressed (step S502: YES), the process proceeds to step S503.

  When the cancel button 804 is pressed (step S502: NO), the processing shown in this flowchart is terminated.

  In step S503, the CPU 201 of the mobile terminal 101 switches to the normal mode.

  Here, the normal mode and the low temperature mode will be described.

  The normal mode is a mode that is applied when the outside temperature satisfies a predetermined temperature (when the temperature is equal to or higher than the predetermined temperature) and when an operation on the touch panel is performed using a touch pen.

  Screens displayed when the normal mode is applied are screens such as FIG. 6A and FIG. 7A.

  For example, in the screens shown in FIGS. 6A and 7A, the back button 601 and the forward button are compared with the screens shown in FIGS. 6B and 7B (screens displayed in the low temperature mode). 602, the registration button 701 is small.

  This is because it is operated with a finger or a touch pen, so there is little need to display a large button, but by increasing the amount of information displayed on one screen (by increasing the display area), the user can Convenience can be improved.

  Therefore, the button (the area where the button is displayed (that is, the operation unit)) is displayed smaller than in the low temperature mode.

  The low temperature mode is when the outside temperature does not meet the specified temperature (if it is less than the specified temperature) or when operating on a swaying ship, and when the touch panel is operated without using the touch pen. Applicable mode.

  Screens displayed when the low temperature mode is applied are screens such as FIG. 6B and FIG. 7B.

  For example, in the screens shown in FIGS. 6B and 7B, each button (return button 603, forward button 604, and forward button 604, compared to the screens displayed in the normal mode (FIGS. 6A and 7A) A registration button 702) is displayed large.

  In addition, the scroll bar 703 in FIG. 7B is also displayed larger than the scroll bar in FIG. As described above, the area that can be operated by the user (the area that receives an instruction from the user) is displayed larger than the button, so that the operability of the user can be improved.

  This may be done by wearing thick gloves when the temperature is low, and when operating in a rocking condition such as on a ship, the contact area will be large and a small button will cause an error. This is to reduce such erroneous operations because a case where the button is pressed or a case where the button is not pressed even if the button is intended to be pressed occurs.

  In the example shown in FIGS. 6 and 7 for the low temperature mode, the example in which the size of the button displayed on the actual display unit is increased has been described.

  On the other hand, FIG. 10 shows an embodiment in which an area for detecting an instruction (instruction reception area) is wider than that in the normal mode without changing the screen configuration actually displayed as in the normal mode.

  FIG. 10A is a screen corresponding to the screen shown in FIG. In FIG. 10A, an area 1001 surrounded by a broken line is an area for detecting pressing of the return button. That is, when an area 1001 surrounded by a broken line is pressed, the user's instruction is detected as a return button being pressed.

  Similarly, an area 1002 surrounded by a broken line is an area for detecting pressing of the forward button.

  FIG. 10B is a screen corresponding to the screen shown in FIG. In FIG. 10B, an area 1003 surrounded by a broken line is an area for detecting the pressing of the registration button.

  As described above, the screen that is actually displayed on the display unit (the screen that is actually viewed by the user) remains the same as that in the normal mode, and the area for detecting the button press can be widened. It is possible to solve. As a result, it is possible to reduce erroneous operations while securing the amount of information that can be displayed on one screen.

  Moreover, about low temperature mode, other embodiment of the example demonstrated in FIG. 6, FIG. 7 is described with reference to FIG.

  FIG. 11A shows an embodiment when the display in the normal mode in FIG. 6A is changed to the low temperature mode.

  The return button 1101 and the forward button 1102 in FIG. 11 (A) have a space (gap) between the two buttons compared to the return button 601 and the forward button 602 in the normal mode of FIG. 6 (A). it's shown. Only the displayed button areas 1101 and 1102 can detect user instructions.

  In this way, it is possible to reduce the probability of pressing the adjacent button by mistake when the hand is shaking at low temperatures by widening the interval between buttons in the normal mode in the low temperature mode. Have.

  Similarly, FIG. 11B is an embodiment when the display in the normal mode in FIG. 7A is changed to the low temperature mode.

  In FIG. 11B, a registration button 1103 similar to the registration button 701 in FIG. 7A is displayed, but the next line 1104 column is blank and nothing is displayed. The area (instruction reception area) for detecting the instruction of the registration button may be the same size as the registration button 1103, or as an enlarged range as shown in FIGS. 10A and 10B. Also good.

  Similar to the case of FIG. 11 (A), in FIG. 11 (B), the distance between the buttons in the normal mode is wider in the low temperature mode, so that when the hand shakes at low temperatures, This has the effect of reducing the probability of pressing the button.

  Further, the low temperature mode will be described with reference to FIG. 12 as a modified example of FIG. 6 (B) and FIG. 7 (B).

  FIG. 12 (A) is a modified example in the low temperature mode of FIG. 6 (B). The area where the return button 1201 in FIG. 12A is displayed is the same as the return button 603 in FIG. 6B, but the area where the instruction is detected (instruction reception area) is an area surrounded by a broken line. Only 1202 is set, and an interval with an area (instruction reception area) in which an instruction for a forward button is detected is provided.

  Such a control has the effect of reducing the probability of accidentally pressing the adjacent button when the hand is shaking at low temperatures.

  FIG. 12B is an example in which the low temperature mode of FIG. 7B and FIG. 10B are combined, and an area for detecting the instruction of the registration button (instruction reception area) is spaced. is there. An area (instruction reception area) 1203 for detecting an instruction surrounded by a broken line in FIG. 12B is set wider than the registration button 1204, but the interval between the adjacent registration buttons 1205 is displayed. The width is set smaller than 1204 and 1205.

  The control of FIGS. 11 and 12 has an effect of reducing the probability of erroneously pressing the adjacent button when the hand is shaking at low temperatures.

  3 to 5, when it is considered that an operation is performed by a finger wearing a glove, it is possible to reduce erroneous operations by expanding a region for detecting instructions on the touch panel. .

  On the other hand, even when the outside air temperature is low, when operating using a touch pen instead of a finger, there is a low risk of erroneous operation due to the wide contact area, so a normal screen configuration makes it possible to The amount of information that can be displayed on the screen can be secured, and the convenience for the user is not impaired.

  In addition, when the outside temperature of the environment that is normally used is low and the environment that is worn with gloves is the default, the instruction reception area from the user is usually large and the amount of information that can be displayed on one screen is small, but the outside temperature is When the temperature is within the range of normal temperature, the user's convenience can be improved by narrowing the instruction receiving area and increasing the amount of information that can be displayed on one screen.

  It should be noted that the configuration and contents of the various data described above are not limited to this, and it goes without saying that the various data and configurations are configured according to the application and purpose.

  Moreover, the program in this invention is a program which makes a computer perform the process of FIGS. The program in the present invention may be a program for each process in FIGS.
