  In the present embodiment, the mat system shown in FIGS. 1 and 2 is used as a lower limb training system. Hereinafter, the lower limb training by the present system will be described with reference to the training screen displayed on the television monitor 5.

  FIG. 3 is an exemplary diagram of a training screen according to the embodiment. Referring to FIG. 3, the training screen displayed on the television monitor 5 by the processor 11 is a remaining time display unit 16 for displaying the remaining training time, a score display unit 18 for displaying the score, and 4 arranged in a horizontal line. This includes the hole images H1 to H4. The processor 11 displays a mole character (target) Tg that appears as “nu” from the hole images H1 to H4, and returns (withdraws) to the hole images H1 to H4.

  In this case, the processor 11 causes the mole character Tg to appear at random from the hole images H1 to H4. Mole characters Tg can appear one by one, and a plurality of mole characters Tg can appear at the same time. A plurality of mole characters Tg appear on the screen, but the appearance timing can be shifted little by little. Furthermore, each mole character Tg can be displayed at different speeds of appearance and withdrawal. In this case, the speed of appearance and withdrawal can be randomly changed for each mole character Tg.

  The four hole images H1 to H4 correspond to the four step areas ST1 to ST4 (foot switches SW1 to SW4) in FIG. Here, the hole images H1 to H4 may be collectively referred to as the hole image H, the step regions ST1 to ST4 in FIG. 1 may be collectively referred to as the step region ST, and the foot switches SW1 to SW4 may be collectively referred to as the foot switch SW. When the player depresses the step region ST and causes the corresponding foot switch SW to transition from OFF to ON, the processor 11 superimposes the hole image H corresponding to the foot switch SW on the translucent sole image 20. Is displayed. Note that the foot image SW imitating the left foot sole is displayed when the foot switch SW1 or SW2 transitions from OFF to ON, and the foot sole imitating the right foot sole is displayed when the foot switch SW3 or SW4 transitions from OFF to ON. An image 20 is displayed.

  Then, when the player depresses the step region ST corresponding to the hole image H where the mole character Tg is located at the timing when the mole character Tg appears, the foot switch SW changes from off to on. Over the back image 20, a mole character Tg that has been flattened by being stepped on "Mnu" is displayed. In the example shown in the figure, the mole character Tg appearing from the hole image H3 is stepped and flattened. If the mole character Tg can be stepped on in a timely manner, one point is added to the score display unit 18.

  Next, the flow of processing by the processor 11 will be described using a follow chart.

  FIG. 4 is a flowchart showing the flow of processing by the processor 11 of FIG. Referring to FIG. 4, in step S1, processor 11 performs initial setting of the entire system. Specifically, the system and each variable are initialized.

  In step S3, the processor 11 calculates the remaining training time. In the present embodiment, since the video frame is updated every 1/60 seconds (step S25 described later), the remaining time can be calculated by counting the number of video frames. In this embodiment, the training time is 5 minutes. In step S4, the processor 11 sets a numerical image representing the remaining time calculated in step S3 (image storage position and display position) for display on the remaining time display unit 16.

  In step S5, the processor 11 determines whether or not the remaining time becomes 0. If the remaining time becomes 0, the processor 11 proceeds to step S31, sets the result screen, and proceeds to step S25. Otherwise, the processor 11 proceeds to step S9.

  In step S9, the processor 11 controls the appearance and speed of the mole character Tg. That is, the processor 11 determines the hole image H in which the mole character Tg appears. In this case, one hole image H or a plurality of hole images H may be used. Further, the processor 11 determines which type of mole character Tg is to appear in the hole image H in which it is determined that the mole character Tg appears. In this case, the type is the speed of appearance and withdrawal, and in the present embodiment, large, medium, and small are prepared, and different colors are attached thereto. When there are a plurality of hole images H that are determined to cause the mole character Tg to appear, the type of the mole character Tg is determined for each hole image H. Further, the processor 11 randomly determines the hole image H in which the mole character Tg appears, and also randomly determines the type of the mole character Tg at that time.

  FIG. 5 is a flowchart showing the mole control process in step S9 of FIG. Referring to FIG. 5, in step S50, processor 11 determines whether mole character Tg is appearing or withdrawing from hole image H, that is, animation of mole character Tg in hole image H is referred to. Is being executed, the process proceeds to step S58 if it is appearing or withdrawing, and in other cases, that is, if the mole image Tg is not present in the hole image H, the process proceeds to step S52.

  In step S52, the processor 11 determines whether or not the mole character Tg appears from the hole image H based on the random number. In step S54, the processor 11 proceeds to step S56 if it is determined to cause the mole character Tg to appear, otherwise proceeds to step S58. In step S56, the processor 11 selects one of the three types of mole characters Tg based on the random number. In step S57, the processor 11 sets an animation of the selected mole character Tg.

  In step S58, the processor 11 determines whether or not the processing of steps S50 to S57 has been completed for all the hole images H. If completed, the processor 11 returns. If not, the processor 11 returns to step S60. Proceed to In step S60, the processor 11 proceeds to the next hole image H, and proceeds to step S50.

  Returning to FIG. 4, in step S <b> 11, the processor 11 refers to the on / off information of the foot switch SW acquired in step S <b> 33 described later, and the occurrence of a transition from off to on of the foot switch SW, i.e., trigger generation. Check for the presence or absence. In step S13, the processor 11 proceeds to step S15 if a transition from off to on has occurred, otherwise proceeds to step S25. The transition from OFF to ON of the foot switch SW occurs when the player raises and lowers the foot placed on the stepping area ST. Therefore, the occurrence of the transition from the off state to the on state of the foot switch SW means that the player has performed a step.

  In step S15, the processor 11 animates the foot image 20 at the position of the hole image H (hereinafter referred to as “stepping hole image H”) corresponding to the foot switch SW in which the transition from OFF to ON has occurred. Set still animation). In step S17, the processor 11 determines whether or not the mole character Tg exists in the tread hole image H, that is, whether or not the mole character Tg has been successfully stepped on. When the player steps, that is, when the foot switch SW transitions from OFF to ON, the presence of the mole character Tg in the tread hole image H means that the mole character Tg has been successfully stepped on. Means that.

  In step S19, the processor 11 proceeds to step S21 when determining that the stepping is successful, and proceeds to step S25 otherwise. In step S21, the processor 11 sets an animation in which the mole character Tg arranged in the tread hole image H becomes flat as a success effect. In this case, the setting of the animation of the mole character Tg placed in the tread hole image H set in step S9 is invalid.

  In step S23, the processor 11 adds one point to the current score for display on the score display unit 18, and sets a numeric image representing the score after the addition (image storage position and display position).

  In step S25, the processor 11 proceeds to step S27 if there is an interrupt due to the video synchronization signal, and returns to the same step S25 if waiting for an interrupt. The interruption by the video synchronization signal occurs at 1/60 second intervals, for example.

  In response to the interruption by the video synchronization signal, in step S27, the processor 11 updates the display image (video frame) of the television monitor 5 based on the settings in steps S4, S9, S15, S21, and S23. Further, in response to the interruption by the video synchronization signal, the audio processing in step S29 is executed, thereby outputting an audio guide, music, sound effects, and the like. Then, the process proceeds to step S3.

  An interrupt is generated in response to the signal from the IR receiver 15 of the adapter 1 transitioning from the low level to the high level, and the processor 11 starts the infrared code (IR code) acquisition process in step S33. After the start, the processor 11 executes IR code acquisition processing by a timer interrupt. The IR code acquired at this time includes on / off information of the foot switch SW.

  As described above, according to the present embodiment, the player can step on the mole character Tg that appears and withdraws through the sole image 20 by moving the foot. Therefore, a so-called mole hitting game can be performed using the legs, and as a result, the player can train the lower limbs while having fun.

  Further, the processor 11 can cause mole characters Tg to appear simultaneously from at least two hole images H. Therefore, compared with the case where the mole character Tg appears and withdraws one by one, the degree of difficulty can be increased and training that is hard to get tired can be provided.

  Furthermore, when the new mole character Tg appears, the processor 11 can change the speed of appearance and / or withdrawal of the mole character Tg. Further, the processor 11 makes the speed of appearance and / or withdrawal of the mole character Tg appearing from the hole image H different from the speed of appearance and / or withdrawal of another mole character Tg appearing from the other hole image H. Can do. Therefore, the difficulty level is high when the speed of appearance and / or withdrawal is high, and the difficulty level is low when the speed of appearance and / or withdrawal is slow, so that the difficulty level can be adjusted by adjusting the speed of appearance and / or withdrawal.

  Further, the processor 11 sets the appearance timing so that the other mole character Tg appears while the other mole character Tg is displayed when the appearance timings of at least two mole characters Tg are different. Can do. Therefore, compared with the case where the mole character Tg appears and withdraws one by one, the degree of difficulty can be increased and training that is hard to get tired can be provided. For example, the processor 11 sets the appearance timing so that the other mole character Tg starts appearing while the other mole character Tg appears. Further, for example, the processor 11 sets the appearance timing so that the other mole character Tg starts to appear while the other mole character Tg is withdrawn.

  Further, the processor 11 causes the mole character Tg to appear at random. Therefore, compared with the case where the mole character Tg appears in a predetermined order and position, the difficulty level can be increased and training that is hard to get tired can be provided.

  Further, the processor 11 can randomly change the speed of appearance and / or withdrawal of the mole character Tg. Therefore, compared with the case where it appears and / or withdraws at a predetermined speed for each mole character Tg, the degree of difficulty can be increased and training that is hard to get tired of can be provided.

  Further, the processor displays a translucent sole image 20. Therefore, even when the sole image 20 is displayed, the player can visually recognize the hole image H and / or the mole character Tg displayed in the back, and can improve the interest.
