This portable game apparatus includes a portable multifunction terminal capable of enjoying a game while having functions of a mobile phone terminal, a portable music / image playback terminal, and the like in addition to a device dedicated to the game.

    In such portable computers, in order to enlarge the display area of the display as much as possible, there is a strong tendency to use the input method from the keyboard format to the touch panel format using the display surface of the display. In this case, operation keys for inputting user instructions are also displayed on the display as a so-called graphical user interface (GUI), and the user inputs various commands to the portable computer via the GUI. To do.

    Conventionally, the user interface component displayed in such a graphic has a default display position on the display on the assumption that the user's dominant hand is right-handed (or left-handed), and left-handed (or When a user who is right-handed) changes his handedness, the user has to open a setting screen provided separately from the normal operation screen of the application and set it again, which is complicated and takes time. There was an inconvenience.

    Therefore, a pressure sensor is provided on the right or left side of the device casing, and the user detects the side (right side or left side) holding the device casing, which is opposite to the side holding the device casing. A technique has been proposed in which a side arm is determined as a dominant arm and an operation key is displayed at a position on the display corresponding to the dominant arm (Patent Document 1).

JP-A-9-305315

    However, this method cannot detect the holding side of the device casing unless the user accurately holds the part of the device casing where the pressure sensor is arranged. There is a disadvantage that occurs.

  Therefore, the present invention is a portable computer such as a portable game device having a small-sized display having a touch panel type input function on which a GUI is displayed. It is an object of the present invention to provide a portable computer that can be switched and set.

A first aspect of the present invention includes a main body (2) and a display (3) that also serves as a touch panel type input unit (5) provided in the main body (2), and a predetermined display position ( In the portable computer (1) capable of executing processing according to the user interface by touching the user interface component (19) displayed in a form corresponding to the dominant arm setting state in (RDP),

    Embodiments of the present invention will be described below with reference to the drawings.

    FIG. 1 shows a portable game device as a game machine constituting a portable computer. As shown in FIG. 1, the portable game apparatus 1 has a main body 2 made of a portable casing, and the main body 2 is provided with a display 3. The display 3 is a touch panel type input. The player who is also a user of the portable computer and presses various objects such as operation keys, cursors, icons, and characters displayed on the display surface 3a of the display 3 with a finger. The portable game apparatus 1 can be made to perform various processes corresponding to the object. Since the touch panel type input method is already known, detailed description thereof is omitted here. In the case of the portable game apparatus 1 shown in FIG. 1, all inputs are made by touching the display surface 3a of the display 3 with a finger.

    As shown in FIG. 3, the portable game device 1 that is a portable computer has a main control unit 6, and the main control unit 6 includes the touch panel type input unit 5, the game, and the like described above via the bus line 4. The progress control unit 9, the display 3, the main body posture detection control unit 11, the input interface display control unit 12, the program memory 13, the posture detection sensor 15 and the like are connected. These components are all installed in the main body 2, and when the user carries the main body 2, the portable game apparatus 1 that is a portable computer is carried. Note that the block diagram shown in FIG. 1 exemplarily shows only the portion related to the present invention, and does not show the entire configuration of the portable game apparatus 1 that is an actual portable computer.

      The portable game device 1 which is a portable computer shown in FIG. 2 is configured such that the computer reads and executes a predetermined program stored in the program memory 13 so that a CPU or memory (not shown) can perform multitasking. Thus, the operation is performed in a time-sharing manner, and the functions shown in each block shown in FIG. 1 are executed. However, the portable game device 1 which is a portable computer can be configured with hardware corresponding to each block, and each block is controlled by a CPU or MPU provided in a distributed manner in each block. It is also possible to configure.

    Since the portable game device 1 which is a portable computer has the above-described configuration, when the user plays a game, the touch panel type input unit 5 shown in FIG. 1 is operated to instruct the start of the game. In response to this, the main control unit 6 instructs the game progress control unit 9 to execute the game, and the game progress control unit 9 reads a predetermined game program GPR from the program memory 13 and executes it.

    In a game based on the game program GPR, for example, as shown in FIG. 1, an object set by a game progress control unit 9 in a two-dimensional or three-dimensional virtual space set in a memory (not shown) in the game progress control unit 9 Based on the above, a predetermined game image IG is displayed on the display surface 3 a of the display 3. The game image IG includes, for example, an image of the building 16 and the character 17 that can be operated by the user. In addition, the input interface display control unit 12 displays an image of the operation button 19 as an operation key as a user interface component on the display 5 on the left side of FIG. The The position corresponding to the operation button 19 displayed on the display 6 by the user's finger, for example, any one of the four arrows 19 a, 19 b, 19 c, and 19 d projected and displayed in the vertical and horizontal directions of the operation button 19 When the vicinity of the arrow is touched, the touch panel type input unit 5 detects the coordinates of the contact position by the user's finger based on the operation key control program described later, and the arrows 19a, 19b, 19c of the operation buttons 19 displayed on the display 6 are displayed. , 19d, the direction DN indicated by the user is calculated by a known method, and the result is output to the game progress control unit 9. Here, an image that is mainly displayed on the display other than an image such as an operation key that is a user interface component, that is, a game image IG that is controlled by a command input via the operation key is referred to as a control target image. Called.

    In the game progress control unit 9, based on the direction DN calculated by the input unit 5, control for moving the image of the character 17 of the game image IG that is the control target image in the direction DN indicated by the user on the screen. To proceed with a given scenario.

    At this time, the position where the operation button 19 is displayed on the display 6 by the input interface display control unit 12 is the lower left part of the display surface 6 a of the display 6 in FIG. 1, which is displayed on the portable game apparatus 1. The game image IG is displayed so as to be located in the lower left part. In this case, as a matter of course, the game image IG is arranged such that the upper part of the game image IG is arranged on the upper side of the display surface 6a of the display 6 in FIG. 1, and the lower part of the display surface 6a of the display 6 in FIG. The lower position of the game image IG is arranged on the side, and a normal position display state is set. This “normal position display state” means that when the user holds the portable game device 1 shown in FIG. 1 with the right hand 20 and the left hand 21 shown in FIG. This is a state in which the upper middle part is displayed in the upper side.

    In the case of FIG. 1, since the user operates the operation button 19 with the thumb 20a of the left hand 20, it is estimated that the user is right-handed. Usually, the input interface display control unit 12 displays an operation button 19 as an operation key for instructing a moving direction of the character 17 on the lower left part of FIG. Right-handed display is the default value. The setting state of the dominant hand in the current portable game device 1 is stored in an appropriate memory in the input interface display control unit 12, and this dominant arm setting state is appropriately set by changing the dominant arm described later. The content is switched and updated between “right-handed” and “left-handed”.

    In this case, at the position of the right-handed operation button 19 displayed by default by the input interface display control unit 12, the arrangement is difficult for a left-handed user who wants to operate the operation button 19 with the thumb 21a of the right hand 21. . Therefore, even if the left-handed user is in the middle of a game scenario by the game progress control unit 9, the main body 2 of the portable game device 1 is displayed on the operation button 19 displayed on the display 6. In order to arrange on the left hand 21 side, it is inverted 180 degrees in the directions of arrows A and B in the horizontal plane.

    While the user is playing the game, and thus, during the progress control of the game scenario by the game progress control unit 9, the force that the main body 2 of the portable game device 1 rotates in the horizontal direction (while the main body 2 rotates in the three-dimensional direction) When the rotation has a horizontal component, any rotation mode may actually be applied), and the three-dimensional acceleration sensor that is the posture detection sensor 15 detects the movement and acts on the main body 2. The acceleration is output as a signal SG to the rotation angle determination means, the dominant arm change request presence / absence determination means, and the main body posture detection control section 11 as a timing determination section. The three-dimensional acceleration sensor that is the posture detection sensor 15 is a known sensor that can measure acceleration in a three-dimensional direction (which is a vector value and has a magnitude and a direction). The acceleration sensor can always detect a three-dimensional acceleration acting on the main body 2 and output the measurement result as a signal SG.

    The main body posture detection control unit 11 calculates and integrates the horizontal component of the signal SG from the signal SG to calculate the rotation angle of the main body 2 in the horizontal plane, and the rotation angle of the main body 2 in the horizontal plane. While calculating α, the posture detection sensor 15 starts to move the main body 2 in the horizontal direction (rotational movement having a horizontal component), and therefore the posture detection sensor 15 detects the movement of the main body 2 and detects the signal SG. The calculation of the elapsed time T from the point in time when the signal is output is started. The main body posture detection control unit 11 determines whether or not the main body 2 has rotated 180 degrees in the horizontal plane within a predetermined time DT, for example, within 1 second, and within a predetermined time, the main body 2 has rotated 180 degrees in the horizontal plane. If it is determined that the user's dominant arm change request has been input via the main body 2, the input interface display control unit 12 performs a display position change operation of the operation button 19 as an operation key, which will be described later, and Inverts the game image IG. Further, if the main body 2 does not rotate 180 degrees within the horizontal plane within a predetermined time, it is determined as an unnatural operation as a command operation for inputting a dominant arm change request to the portable game apparatus 1. That is, it is determined that the main body 2 is rotated accidentally or regardless of the presence of the command input request of the user's dominant arm change request, and the user's dominant arm change request is not input. And the signal SG from the attitude detection sensor 15 is ignored, and no processing is performed thereafter.

    Note that the rotation angle of the main body 2 when determining that the user's dominant arm change request is input is not limited to 180 degrees, and any angle range that can be estimated that the main body is inverted in a horizontal plane is used. The angle may be set, and may be set in a range of about 150 to 210 degrees. Further, in the body posture detection control unit 11, not only the rotation angle of the main body 2, but also the action mode of acceleration when the main body 2 is rotated, the rotation speed duration time of the main body 2 and / or the rotation movement duration time in the horizontal rotation direction. As a parameter, the presence / absence of the input of the user's dominant arm change request is calculated and estimated, and when a smaller rotation angle (for example, a rotation of 150 degrees of the main body 2) is detected. It is also possible to calculate whether or not a dominant arm change request has been input, and to enable quick execution of the dominant arm change process.

    For example, normally, when the user performs an operation that rotates the main body 2 unintentionally or unintentionally, and when the main body 2 naturally rotates for some reason, it acts on the main body 2. The acceleration tends to be omnidirectional in the three-dimensional direction, the fluctuation of the rotation speed of the main body 2 in the horizontal direction is large, and the rotation direction is always constantly changing in the three-dimensional direction. Further, it is considered that the rotational movement duration time often shows an intermittent pattern in a short time. On the other hand, when the user rotates the main body 2 in the horizontal plane with a clear intention of changing the dominant arm, the elements constituting the rotation operation of the main body 2, that is, the direction and speed of acceleration thereof. Is the main component for generating the rotation of the main body 2 in the horizontal plane, and the acceleration acting on the main body 2 is a horizontal rotation in which the horizontal component is larger than the other direction components. The directivity of is strong. As a result, the fluctuation of the rotation speed of the main body 2 in the horizontal direction is reduced, and the rotation direction is also substantially constant in the horizontal direction.

    Therefore, the main body posture detection control unit 11 not only calculates the horizontal rotation angle of the main body 2 from the signal SG from the posture detection sensor 15 but also the rotation mode such as the direction of acceleration and speed constituting the rotation operation. If it is determined that the directionality of rotation in the horizontal direction is strong, it can be determined that a user's dominant arm change request is input via the main body 2. Specific acceleration values, speed directions, and the like may be appropriately set through experiments. As described above, it is possible to perform more accurate determination by determining whether or not there is an input of the dominant arm change request by the user in a form using the rotation mode of the main body 2 as a parameter. If the main body posture detection control unit 11 determines that the dominant arm change request is not detected from the detected rotation of the main body 2, the main body 2 rotates 180 degrees in the horizontal direction within a predetermined time DT. Is completed, the dominant arm change processing request signal S1 described later is not output to the input interface display control unit 12. Therefore, the subsequent reverse display processing of the game image IG described later and the operation button 19 are not performed. The display position switching control process is not performed.

    Note that the user's dominant arm change is determined by measuring the elapsed time T from the start to the end of the 180-degree rotation operation of the main body 2 by the user and determining whether the rotation operation is completed within the predetermined time DT. It is possible to prevent malfunctions caused by the user's casual rotation and movement of the main body 2 that are not based on the request.

    When the main body 2 of the portable game apparatus 1 is rotated 180 degrees in the horizontal plane, the main body 2 in a state as shown in FIG. 1 before the rotation, for example, as shown in FIG. 1 is reversed, and the game image IG is also not shown, but from the normal position display state shown in FIG. 1, the game game IG is turned upside down, that is, with the right hand 20 and the left hand 21, the portable game apparatus 1 shown in FIG. When the game image IG is held on the display 6, the game image IG is in a reverse position display state where the lower side in the figure is up for the user. At this time, the display position of the operation button 19 that has been displayed at the lower left position LDP in FIG. 1 is also changed to the upper right position RUP in FIG.

    In this state, the left-handed user turns the game image IG upside down, and the display position of the operation button 19 changes to the upper right of the display surface 6a of the display 6. Therefore, the visibility of the game screen and the operability of the operation button 19 are improved. Is extremely bad.

    Therefore, if it is determined that the main body 2 has rotated 180 degrees within the horizontal plane within a predetermined time, the main body posture detection control unit 11 has input the dominant arm change request by the user as described above. It determines with a thing, and outputs dominant hand conversion process request signal S1 with respect to the input interface display control part 12 which is a control object image reverse display means. In response to this, the input interface display control unit 12 switches the dominant-arm setting state stored in a memory (not shown) from the right-handed state so far to the left-handed state. When the dominant hand setting state is switched from the right-handed state to the left-handed state, the input interface display control unit 12 continues to start the dominant-arm conversion process. Specifically, the game image IG currently displayed on the display 3 is reversed by 180 degrees from the display state shown in FIG. 1 displayed before the main body 2 starts rotating in the horizontal plane. Let That is, the game progresses so that the upper and lower sides of the game image IG are displayed in the reverse state with respect to the display state shown in FIG. 1, that is, in the normal position display state in which the main body 2 is reversed 180 degrees. Commands to the control unit 9.

    In response to this, the game progress control section 9 immediately displays the game image IG upside down as shown in FIG. 2, and the main body 2 is inverted (the upper and lower sides of the main body 2 are opposite to the previous state). So that the normal position display state is obtained. Further, the input interface display control unit 12 displays the operation button (operation key) 19 displayed in the upper right position RUP in FIG. 2 when the dominant arm setting state in the memory is switched from the right-handed state to the left-handed state. The position is controlled to be changed to the display position in the left-handed state stored in the memory, that is, the lower right position RDP in FIG. 2 on the display 6 of the main body 2 in the inverted state. In accordance with the display position switching process of the display position of the operation button (operation key) 19, the touch panel type input unit 5 displays the operation button (operation key) 19 portion displayed at the lower right position RDP in FIG. 1, an operation button (operation key) control program for controlling the touch input operation of the touch panel type input unit 5 so that the input operation of the predetermined operation button 19 can be performed is executed by the lower left position LDP (FIG. When the operation button 19 is displayed at the lower right position RDP in FIG. 2 from the operation button (operation key) control program used when the operation button (operation key) 19 is displayed at the upper right position RUP in FIG. Switch to the operation button (operation key) control program used for.

    As described above, the display position of the operation key on the display according to the right-handed or left-handed hand setting state is stored in the memory, and the operation button corresponding to the operation key displayed at the display position is stored. Since the control unit program is stored so as to be executable, these switching operations can be easily performed. As a result, the touch panel type input unit 5, and hence the lower right position RDP of the display 6 in FIG. 2 is effective as the input unit, and the user moves and displays the lower right position RDP of the display 6 with the thumb 21 a of the right hand 21. The button 19 can be operated.

    Thereafter, in the state of the main body 2 shown in FIG. 2, the left-handed user operates the operation button 19 with the thumb 21a of the right hand 21 to execute the game, but again switches the play with the right-handed user. In this case, as described above, the main body 5 of the portable game apparatus 1 is further inverted 180 degrees in the horizontal plane and returned from the state of FIG. 2 to the state of FIG. Then, 180 degree inversion of the main body 5 is detected by the posture detection sensor 15 and the main body posture detection control unit 11, and the dominant arm setting state is switched from left-handed to right-handed, and the game progress control unit 9 and the input interface display control unit 12 The game image IG is reversely displayed from the state shown in FIG. 2 to the state shown in FIG. 1, and the operation button 19 is moved from the lower right position RDP of the display 6 in FIG. 2 to the lower left position LDP in FIG. It is displayed in the form. Then, the operation button control program is for the right-handed operation button 19 that is switched to the lower-left position LDP in FIG. 1 from the left-handed operation button 19 that has been displayed in the lower-right position RDP in FIG. The right-handed user can operate with the left hand thumb 20a.

    As already described, when the handedness setting state in the portable game apparatus 1 is right-handed, as shown in FIG. 1, the arrangement display position of the operation button 19 is the lower left position LDP in FIG. When the dominant arm setting state in the portable game apparatus 1 is left-handed, as shown in FIG. 2, the arrangement display position of the operation button 19 is set to the lower right position RDP in FIG. The arrangement display position of the operation button 19 is preset by the input interface display control unit 12 in accordance with the dominant arm setting state. That is, the input interface display control unit 12 previously corresponds to the display position of the operation button 19 on the display 6 and the operation button 19 displayed at each display position in accordance with the right-handed or left-handed handedness setting state. The operation button control program is stored in an appropriate memory, and the display position of the operation button 19 on the display 6 is set each time the user inputs a dominant arm change request for rotating the main body 2 in the horizontal plane. It switches between the display positions of the operation buttons 19 of the dominant hand. At the same time, the operation button control program for each operation button 19 displays the operation buttons 19 in order to invalidate the operation buttons 19 that have been displayed so far, and to activate the operation buttons 19 that are newly switched and displayed. Control is performed so that only the operation button control unit program for the operation button 19 newly switched and displayed in accordance with the switching is operated effectively. This ensures a smooth input operation switching operation.

    In addition, the arrangement display position of the operation button 19 in each dominant-arm setting state is not necessarily fixed, and the right-hand and left-handed users' game images IG are displayed before and after 180 degrees inversion in the horizontal plane of the main body 2. In the state, if it is right-handed, the position of the left-right part of the display 6 and the right-hand part of the display 6 in the case of left-handed may be anywhere. Similarly, other user interface components may be displayed at appropriate predetermined positions according to the operation.

    In the above-described embodiment, in the default state, as shown in FIG. 1, the user is right-handed. Therefore, the handed arm setting state in the portable game apparatus 1 is a right-handed state, so that it can be adapted to a left-handed user. Inverted the main body 5 of the portable game apparatus 1 in the horizontal plane, and changed the display state of the game image IG and the operation buttons 19 by switching the dominant arm setting state to the left-handed state as shown in FIG. However, on the contrary, in the default state, as shown in FIG. 2, the user is left-handed, so the handed arm setting state in the portable game apparatus 1 is a left-handed state. The main body 5 of the type game apparatus 1 is inverted in a horizontal plane, and as shown in FIG. 1, the dominant arm setting state is switched to the right-handed state, and the display state of the game image IG and the operation buttons 19 is changed. May be.

    In addition to the operation buttons 19 displayed on the display 3, the user interface components include any shapes and arrangements such as buttons, icons, keys, and the like used for input of a touch panel type input unit. It is possible to apply the present invention even if it is a thing. For example, as shown in FIG. 4, a plurality of buttons BT (icons, keys) displayed as user interface components are rotated by a predetermined angle within a horizontal plane from the right-handed display shown in FIG. Thus, the dominant hand setting state is changed according to the present invention, and the state shown in FIG. 5 is changed to the left-handed display. Further, the control target image according to the present invention is not limited to the game image IG, and may be any image as long as it is a normal operation image of an application executed by a program. In other words, the present invention is not limited to a portable game device, but can be applied to all portable computers such as a music player, an information terminal, and a telephone having a display that also serves as a touch panel type input unit. Further, the arrangement of the various buttons BT constituting the user interface components is arbitrary, and the operation mode of those users is also arbitrary. Accordingly, as shown in FIG. 4, the user interface component is arranged on one side of the display 3 so as to be operated with one hand of the user as in FIG. It is also possible to arrange the display 3 on both the left and right sides so that it can be operated with both hands.

    Furthermore, the main body posture detection control unit 11 that is a rotation angle determination means detects acceleration acting on the main body 2 of the portable computer via an acceleration sensor that is the posture detection sensor 15, so that the main body 2 is in a horizontal plane. Although it has been described about the case where it is determined whether or not it has rotated by a predetermined angle, the signal for calculating the rotation angle of the main body is not limited to the signal from the acceleration sensor which is the posture detection sensor 15. That is, as long as it is a posture detection sensor that can detect the posture of the main body 2 in the horizontal plane in real time, the posture variation with time in the horizontal plane of the main body is calculated based on signals output from those sensors. Since the rotation angle of the main body 2 in the horizontal plane can be calculated, any sensor may be used. For example, in addition to the three-dimensional acceleration sensor, the main body 2 is predetermined in the horizontal plane by calculating the angle difference before and after the rotation operation of the main body using a geomagnetic sensor, a direction sensor, a gyroscope, a captured image of the camera, and the like. Of course, it may be configured to determine whether or not the angle has been rotated.
