[Game device]
FIG. 1 is a perspective view showing a use situation of a first embodiment of a game apparatus according to the present invention, FIG. 2 is a block diagram showing the game apparatus of FIG. 1, and FIG. 3 is a functional block diagram showing the game apparatus of FIG. It is.

  As shown in FIG. 1, the game apparatus GM includes a main body 1000 and a pointing device (pointing means) 1100, and a display 2000 is connected to the main body 1000. The game apparatus main body 1000 is connected to the speaker 2020 of the display 2000 and can output the sound of the game to be executed.

  A pair of light emitting diode modules 3000 and 3020 is disposed at a predetermined position in the vicinity of the display 2000, for example, a predetermined position on the display 2000, and the pointing device 1100 detects light emitted from the light emitting diode modules 3000 and 3020.

  As shown in FIG. 2, the pointing device 1100 is provided with a photo sensor 1120 that detects light emitted from the light emitting diode modules 3000 and 3020, a plurality of operation input switches 1140, and an acceleration sensor 1150. Further, the pointing device 1100 calculates image information calculation for calculating coordinates on the image IM indicated by the pointing device 1100 based on the position of light emitted from the light emitting diode modules 3000 and 3020 in the image taken by the photosensor 1120. Unit 1160 (FIG. 4: coordinate detection means 4010). The calculation of the designated coordinates is described in detail in Patent Document 1. As shown in Patent Document 2, it is naturally possible to detect coordinates on a display using raster scanning lines.

  Note that the coordinate detection means 4010 is configured by the image information calculation unit 1160 and the acceleration sensor 1150, and together with the calculation result of the image information calculation unit 1160 based on the images of the light emitting diode modules 3000 and 3020, the movement of the pointing device 1100 by the acceleration sensor 1150 is detected. You may detect a designated coordinate or a designated coordinate change using a detection result.

  The game apparatus main body 1000 drives a CPU 1010 that controls the entire game apparatus GM, a ROM 1030 that stores basic software, a game control program, and the like, a system memory 1020 that stores various data for program execution, and a speaker 2020. An audio signal generation circuit 1040 for generating an audio signal for generating a video signal, and a video signal generation circuit 1050 for generating a video signal for the video IM to be displayed on the display 2000. The acoustic signal generation circuit 1040 and the video signal generation circuit 1050 are connected to the CPU 1010, the ROM 1030, and the system memory 1020 via the interface 1060.

  In the image IM displayed on the display 2000 in FIG. 1, areas (referred to as direction indicating areas) AR1, AR2, AR3, and AR4 are respectively set around the right and left upper and lower sides, and the pointing coordinates by the pointing device 1100 are set to these. The game device GM determines that a direction instruction corresponding to these areas has been made. Direction indication is a right direction when the designated coordinate is the right area AR1, a left direction when the designated coordinate is the left area AR2, an upward direction when the designated coordinate is the upper area AR3, and a downward direction when the designated coordinate is the lower area AR4. Instructed.

  As the shapes of the areas AR1 to AR4, a rectangular shape along the XY direction and other arbitrary shapes can be adopted.

  In the case of a rectangular area, the X coordinate range X11 to X12 of the area AR1, the Y coordinate range Y11 to Y12, the X coordinate range X21 to X22 of the area AR2, the Y coordinate range Y21 to Y22, the X coordinate range X31 to X32 of the area AR3, Y Coordinate range Y31 to Y32, X coordinate range X41 to X42 of region AR4, Y coordinate range Y41 to Y42, X coordinate range Xc11 to Xc12 of region ARv1, Y coordinate range Yc11 to Yc12, X coordinate range Xc21 to Xc22 of region ARv2, When the Y coordinate range Yc21 to Yc22, the X coordinate range Xc31 to Xc32 of the area ARv3, the Y coordinate range Yc31 to Yc32, the X coordinate range Xc41 to Xc42 of the area ARv4, and the Y coordinate range Yc41 to Yc42, Xcij is converted by coordinate conversion. Convert to Xij and convert Ycij to Yij (i = 1, 2, j 1, 2).

  Thus, continuous direction operation input is easy by giving direction directions based on field AR1-AR4.

  A reference position RP related to the direction indication is set at a predetermined position of the image IM, for example, in the center, and becomes a reference for setting a conversion coordinate system to be described later.

  For example, in a dance simulation game in which dancer objects OB1, OB2, and OB3 are displayed on the screen IM and the direction of the dancer's movement is instructed according to the dance rhythm, the direction can be instructed by the pointing device 1100.

  As shown in FIG. 3, the CPU 1010, the system memory 1020, and the video signal generation circuit 1050 function together as an image generation unit 4000 that generates an image IM.

  The CPU 1010 and the system memory 1020 cooperate to function as a game control signal generation unit 4100 that generates a game control signal for controlling the game based on the designated coordinates by the pointing device 1100.

  The CPU 1010 and the system memory 1020 cooperate to function as direction indication area setting means 4110 for setting the areas AR1 to AR4 in the image IM.

[Calibration]
FIG. 4 is a diagram showing a concept of calibration in the game device of FIG. 1, and FIG. 5 is a diagram showing a specific example of calibration in FIG.

  In FIG. 4, when the initial designated coordinate by the pointing device 1100 is the reference position PR (in FIG. 1, the cross-shaped cursor is at the reference position RP and the designated coordinate is the reference position RP). The direction instruction has the same swing width in all directions, up, down, left, and right, and the player can perform the direction instruction with a natural feeling.

  However, as indicated by the current position CP in FIG. 4, when the direction instruction is started from a position displaced in the lower left direction from the reference position RP, the direction instruction by the areas AR1 to AR4 has a bad balance between left and right and up and down. There is a possibility of incorrect input of instructions.

  Therefore, calibration for converting the current position CP to the reference position RP is executed. At this time, when the coordinates (X0, Y0) of the position RP and the coordinates (Xc, Yc) of the position CP are given, the position CP is given a displacement of (X0-Xc) for the X coordinate and (Y0-Yc) for the Y coordinate. It is done.

  As a result of the calibration, a coordinate instruction centered on the current position CP is converted into a direction instruction based on the areas AR1 to AR4. As shown by a two-dot chain line in FIG. 4, areas centering on the current position CP (referred to as conversion direction instruction areas) ARv1, ARv2, ARv3, and ARv4 are set corresponding to the areas AR1 to AR4. When the designated coordinates are included in any one of the conversion direction indication areas ARv1, ARv2, ARv3, and ARv4, it is regarded as a direction indication by the corresponding areas AR1 to AR4. As a result, it is possible to indicate a direction by a natural input operation.

  The size of the areas ARv1 to ARv4 and the positional relationship with the current position CP are not necessarily the same as the size of the areas AR1 to AR4 and the positional relationship with the reference position RP. For example, it is set in consideration of a range in which a sufficient coordinate instruction accuracy by the pointing device 1100 can be obtained.

  The calibration can be performed at various timings, such as when the game is started, when a direction instruction is to be executed in the game, and when the player inputs using the operation input switch 1140 or the like. It is also possible to execute calibration by moving the designated coordinates of the pointing device 1100 outside the screen IM. For example, in a dance simulation game, a dance is performed with the dancer object OB1 as a model, and then the player performs calibration when starting the direction instruction learned from the model in synchronization with the movement of the dancer object OB1. By doing so, good operability can be obtained.

  The CPU 1010 and the system memory 1020 function together as a conversion coordinate system setting unit that sets a conversion coordinate system.

  The indicated coordinates after calibration are converted into a conversion coordinate system and applied to the direction indication determination based on the areas AR1 to AR4.

  The CPU 1010 and the system memory 1020 cooperate to function as detection coordinate conversion means for converting the indicated coordinates into the converted coordinate system, and further determine whether the indicated coordinates are included in the areas AR1 to AR4. Functions as a means.

  Further, the CPU 1010 and the system memory 1020 cooperate to function as the direction control signal generation unit 4150 based on the determination result of the direction determination unit, and to the game control signal generation unit 1140 based on the direction control signal. Make control run.

  As shown in FIG. 5, the conversion direction indication areas ARv1, ARv2, ARv3, and ARv4 are set corresponding to the areas AR1 to AR4 set positions, for example, and sufficient coordinate indication accuracy by the pointing device 1100 can be ensured.

  For example, when the current position CP (Xc, Yc) is displaced in the area AR2 direction (left direction) and the AR4 direction (downward direction) with respect to the reference position RP, the right X coordinate Xc22 of the conversion direction instruction area ARv2 Is matched with the right X coordinate X22 of the area AR, and the upper Y coordinate Yc42 of the conversion direction indicating area ARv4 is matched with the upper Y coordinate Y42 of the area AR.

  At this time, when the distances from the reference position RP to the areas AR1, AR2, AR3, AR4 are XR, XL, YU, YD, and X0−Xc = ΔX, Y0−Yc = ΔY, the distances from the position CP to the areas ARv2, ARv4 Are distances | XL−ΔX | and | YD−ΔY |.

  On the other hand, the regions ARv1 and ARv3 are formed, for example, symmetrically with respect to the regions ARv2 and ARv4 with respect to the position CP, and are disposed inside the regions AR1 and AR3. Thereby, it is possible to guarantee a good coordinate indication accuracy.

  Note that the conversion direction indication areas ARv1, ARv2, ARv3, and ARv4 may be asymmetrically arranged and shaped as long as the coordinate indication accuracy can be ensured.

[Game control program]
Next, a game control program executed in the game device of the first embodiment will be described.

  10 is a flowchart showing the process of the game control program executed by the game device of FIG. 1, FIG. 11 is a flowchart showing the input determination process of FIG. 10, and FIG. 12 is the direction instruction determination process of FIG. It is a flowchart to show.

  In FIG. 10, the game control program causes the game apparatus body 1000 to execute the processing of the following steps.

  Step S1001: First, a game to be executed, for example, a dance simulation game, is initialized by the CPU 1000 and the system memory 1020.

  Step S1002: Following step S1001, the CPU 1000, the system memory 1020, the video signal generation circuit 1050, and the acoustic signal generation circuit 1040 output a model dance image and sound.

  Step S1003: Subsequent to step S1002, the input by the pointing device 1100 is determined by the game control signal generation means 4100.

  Step S1004: Following step S1003, the CPU 1000 and the system memory 1020 determine whether or not the player's input is excellent as a result of the input determination. When it is excellent, the process proceeds to step S1005, and when it is not excellent, the process proceeds to step S1006.

  Step S1005: The CPU 1000, the system memory 1020, the video signal generation circuit 1050, and the audio signal generation circuit 1040 execute processing for providing points to the player.

  Step S1006: The CPU 1000 and the system memory 1020 determine whether or not the game is the final play. If it is the final play, the process is terminated as it is, and if it is not the final play, the process proceeds to step S1007.

  Step S1007: The next play is set by the CPU 1000 and the system memory 1020, and the process returns to step S1002.

  In FIG. 11, the game control program executes an input determination process (step S <b> 1003) by causing the game apparatus body 1000 to execute the processes of the following steps.

  Step S1101: First, the CPU 1000 and the system memory 1020 initialize an internal rhythm counter (not shown) in the dance simulation game. The internal rhythm counter is realized by a counter or the like in the CPU 1010.

  Step S1102: Subsequent to step S1101, the CPU 1000 and the system memory 1020 set the output timing of the model dance.

  Step S1103: Subsequent to step S1102, the game control signal generation unit 4100 determines a direction instruction of the pointing device 1100.

  Step S1104: Following step S1103, the CPU 1000 and the system memory 1020 determine whether or not the determination of the direction instruction for the predetermined number of times of sampling has been completed. When the predetermined number of times is determined, the process proceeds to step S1105, and when the predetermined number of times is not determined, the process returns to step S1103.

  Step S1105: The CPU 1000 and the system memory 1020 evaluate the direction instruction input by the player's pointing device 1100, and execute score addition / subtraction.

  Step S1106: Following step S1105, the CPU 1000 and the system memory 1020 add / subtract the player's life (game continuation point or time). Thereafter, the process ends.

  In FIG. 12, the game control program executes a direction instruction determination process (step S <b> 1103) by causing the game apparatus main body 1000 to execute the processes of the following steps. In the process of FIG. 12, when the designated coordinates of the pointing device 1100 reach an area outside a predetermined coordinate area, calibration is executed according to the coordinate detection of the area.

  Step S1201: First, the CPU 1000 and the system memory 1020 read the designated coordinates (Xc, Yc) of the current position CP.

  Step S1202: Following step S1201, the CPU 1000 and the system memory 1020 determine whether or not the current position CP is within the screen IM. When the current position CP is within the screen IM, the process proceeds to step S1204. When the current position CP is outside the screen IM, the process proceeds to step S1203.

  Step S1203: The CPU 1000 and the system memory 1020 turn on a calibration flag for executing calibration in the next direction instruction determination process.

  Step S1204: The CPU 1000 and the system memory 1020 determine whether or not the calibration flag is ON. When the calibration flag is ON, the process proceeds to step S1205, and when the calibration flag is not ON, the process jumps to step S1206.

  Step S1205: Calibration is executed, and the process proceeds to step S1206.

  Step S1206: Following step S1205, the CPU 1000 and the system memory 1020 obtain a direction instruction, and the process is terminated as it is.

Next, a second embodiment of the game apparatus according to the present invention will be described.
[Game device]

  6 is a perspective view showing a usage situation of the game device according to the second embodiment of the present invention, FIG. 7 is a block diagram showing the game device of FIG. 6, and FIG. 8 is a functional block diagram showing the game device of FIG. FIG. 9 is a diagram showing a concept of direction indication by the pointing device of FIG. In the figure, the same or corresponding parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the first embodiment, coordinate detection is performed on the pointing device 1100 side, but the game apparatus main body 1000 can also perform coordinate detection.

  6 to 9, the ponting device 1200 is formed in a long wand shape, and is provided with a plurality of light emitting units 3040 and 3060 and an operation input switch 1140. On the other hand, a video camera 3100 that detects the light emitting units 3040 and 3060 is disposed at a predetermined position near the display 2000, for example, a predetermined position on the display 2000, and the video camera 3100 is connected to the game apparatus main body 1000. The light emitting units 3040 and 3060 have a light emitting function similar to that of the light emitting diode modules 3000 and 3020.

  The video camera 3100 detects light emitted from the light emitting units 3040 and 3060, and the game apparatus body 1000 detects a coordinate instruction and a direction instruction based on the positional relationship.

  As shown in FIG. 9, the positional relationship between the light emitting units 3040 and 3060, for example, the angles θ1 and θ2 from the vertically lower side of the center line CL of the wand 1200 are associated with the X coordinate, and the height from the light emitting unit 3040 to the light emitting unit 3060 is increased. The heights H1 and H2 can be associated with the Y coordinate. Alternatively, the change from the angle θ1 to θ2 and the change from the height H1 to H2 can be associated with the change of the X coordinate and the Y coordinate.

  As shown in FIG. 7, the video camera 3100 is connected to a CPU 1010 and a system memory 1020 via an interface 1060.

  As shown in FIG. 8, the CPU 1010 and the system memory 1020 function as coordinate detection means for detecting coordinates or coordinate changes based on the images of the light emitting units 3040 and 3060 acquired by the video camera 3100.

[Features obtained by calibration]
As described above, the following situation can be considered as a case where the effect of performing calibration at any time can be obtained.

  For example, a dance game in which the progress of the game is controlled by four-direction operation input information such as “up”, “down”, “left”, “right”, etc., which is input as time information, screen display or voice instruction information In response to this, there is a flag raising game in which two or more controllers are held in the right and left hands and raised and lowered in two directions.

  Taking the case of the above dance game as an example, when inputting using the pointing device in the upward direction twice in quick succession, for example, “up” and “up”, simply as in the conventional patent document 1 When such an operation is performed by a method based on the technique, the pointing device is tilted upward once, the pointing position is quickly returned to the neutral position IM, and the tilting upward is performed again. Even if the user is familiar with the operation to some extent, for example, the hand shakes to the left or right in response to a quick input, or jumps over the area IM which is the neutral position (in this case, the upper area) It is assumed that an input error is determined when the pointing position enters up to an input area in the downward direction opposite to the direction).

  However, by performing calibration when there is an input once in any area (in this case, the upward input area) as in the present application, the player himself is not in the area IM where the player is in the neutral position. For example, even if the hand shakes and moves to the left or right, or if it moves in the opposite direction due to momentum, the software side re-assigns that position as the region IM that is the neutral position (the position where no input is made in either direction). By making the setting, it is possible to avoid such an erroneous input.

  In addition, when the acceleration sensor is used together, for example, when there is a response from the acceleration sensor in the opposite direction to the signal input to the acceleration sensor when input is made to any input area, for example. By performing only the calibration, it is possible to further improve the accuracy of avoiding erroneous input.

  In addition, for example, the present invention exerts its effect even when “lower” and “left” are continuously input.

  For example, when “down” or “left” should be input, if the player is not proficient in the operation, the controller should be tilted down and left without returning to the region IM which is the neutral position. As a result, after performing the downward input, the input is performed obliquely in the lower left direction, and as a result, the operation input in the left direction is not judged and an error occurs, and even if the user intends to input correctly, the game It was impossible to operate well in the course of progress, and there were cases where it was intriguing.

  However, when processing such as this application is performed, the calibration processing is performed after detection of the area in the downward direction, so even if input is performed in the left direction as it is (actually left diagonally downward), the operation is performed. As the signal processing is input as “left” and “down”, it is possible to control the game progress more easily reflecting the player's own intention.

  Furthermore, by performing calibration using the acceleration sensor together as described above, even when inputting downward, returning to the center position once and inputting further to the left as in the case of the prior art, Even if the input is performed downward and the input is performed in the left direction without returning to the center position, the game progress control can be performed in the same manner, and the conventional technique is used (when calibration is not performed). It is possible to provide a lighter and easier continuous direction operation input to a larger number of players.

  The present invention is not limited to the above-described embodiments, and can be applied to any game apparatus and game control program provided with a pointing device capable of instructing coordinates or coordinate changes.
