[0003]

However, the above-mentioned game device is for business use provided in a game arcade or the like, and cannot be used anytime when one wants to enjoy a dance game at home. On the other hand, home-use game consoles can also support dance games, and if you have a home-use footswitch that allows you to input the player's step action in the dance game, you can use it whenever you want to enjoy the dance game at home You can do it. Even in this case, it is desirable that the foot switch be capable of expressing a rhythmic feeling using the whole body in accordance with the music, similarly to the above-mentioned business use.

By the way, when playing a dance game at home, a foot switch is directly placed on the floor surface, and when the player performs a step operation on the foot switch, the position of the foot switch is recognized so as not to deviate from the position of the foot switch under the foot. There is a need to. Also, noise may be generated during the step operation. For this reason, the player sees his or her feet one by one, and it is impossible to drastically reduce the noise in order to suppress the generation of noise. Therefore, in order to enable the player to express a sense of rhythm using the whole body in tune with the music in the same manner as in the above-mentioned business use, the position of the foot switch can be recognized with the sense of the foot and appropriate soundproofing measures must be taken. Need to take. It is also necessary to consider transportation and the like. Furthermore, the same foot switches as described above are used in game machines other than dance game machines, for example, exercise machines, other reflex performance testing machines, and the like. However, foot switches used in these machines have exactly the same problems as above. there were.

[0005] The present invention has been made in view of the above,
The purpose of the present invention is to provide a mat that is used by being superimposed on a footswitch sheet that can be used by being connected to a home-use game machine, and a centerpiece structure when the mat is divided so that it can be easily transported. is there.

Of these data, the polygon vertex address data on the display area is determined by the graphics data generation processor 3 by the polygon vertex coordinate data in the three-dimensional space from the CPU 1 by the movement amount data and rotation amount of the screen itself. By performing coordinate transformation based on the data, 2
This is replaced with polygon vertex coordinate data on the dimension. The luminance data is determined by the graphics data generation processor 3 from the position indicated by the polygon vertex coordinate data after the coordinate conversion from the CPU 1 based on the distance between the light sources virtually arranged.

The start button 22a is for the player to instruct the CPU 1 to start the game program data loaded from the recording medium 30. The select button 22b is used by the player to instruct the CPU 1 to make various selections regarding game program data loaded from the recording medium 30 to the main memory 5. The functions of the first left button 22L1, the second left button 22L2, the first right button 22R1, and the second right button 22R2 differ depending on the game program data loaded from the recording medium 30.

The foot switch device 200 is, similarly to the controller 22, an operation means that can be operated from the outside, and is operated by the player performing a stepping operation (step operation) thereon. Hereinafter, a configuration example of the foot switch device will be described.

(Structural Example of Foot Switch Device) As shown in FIGS. 3 and 4, the foot switch device 200 has a rectangular thin-layer foot switch portion 210 and a thick mat laid thereunder, for example. A part 220. The foot switch section 210 includes, from top to bottom, a first sheet 211 made of a transparent body made of EMMA (ethylene-methyl-methacrylate), a printed second sheet 212 made of soft PVC, and an entire back surface made of soft PVC. Sheet 213 coated with carbon, fourth sheet 214 made of urethane, fifth sheet 215 coated with carbon at an appropriate position on the surface made of PET, and sixth sheet 2 made of EVA
It has 16 six-layer structures. And as shown in FIG.
Each of the six-layer sheets is fixed at its periphery with a polyester tape 218 so as not to be shifted from each other to form the foot switch section 210. In addition, each material is an example, and any material may be used as long as it has the same properties.

Of the above sheets, the first sheet 211
Since the player steps directly on the player, durability is required, and a device devised against slippage in order to ensure a preferable stepping action by the player is employed. In the present embodiment, the first sheet 211 is made of the above-described EMMA, which is a material that is unlikely to cause slippage, and the sheet surface is subjected to, for example, shallow groove processing over the entire surface. For example, a groove is formed by a hot roller, a press or cutting. As the groove pattern, a straight groove 211 parallel to one of the diagonal lines of the foot switch section 210 as shown in FIG.
a, 211a,... are formed. As described above, the diagonal direction is such that, in a dance game, the stepping position is changed in the front, rear, left and right with respect to the center, as described later. This is because there is a risk of slipping at a stepping position parallel to the groove as viewed from the side. By forming the direction of this straight groove parallel to one of the diagonal lines of the foot switch unit 210, the front and rear and left and right directions intersect with the stepping-out direction of the foot, so that a non-slip component exists. It will be. In addition, you may form in parallel to both of a diagonal line. Further, from the viewpoint of the slip prevention effect, for example, the groove pitch is preferably about 2 mm and the groove depth is about 0.02 mm, and the groove cross-section is preferably wedge-shaped or rectangular.

The second sheet 212 is printed via the transparent first sheet 211 so that the position of the foot switch can be recognized. For example, arrow marks (→, ←, ↑, ↓) indicating directions from the center are printed at the positions of the front, rear, left and right foot switches with respect to the center. By performing printing on the second sheet 212, it is possible to prevent the print content from being erased even when the player repeatedly performs the stepping operation.

The third sheet 213 is coated with carbon on the entire back surface, and the carbon forms the common electrode 213a of the foot switch. Carbon is suitable as an electrode of a foot switch because it can be coated with a thin film and has excellent conductivity and pressure resistance.

The fourth sheet 214 is used as a spacer that can be elastically deformed until its thickness becomes almost zero when the player steps on the player, and the fourth sheet 214 is positioned at an appropriate position on the center of the sheet. And a plurality of small holes 214a, 214a,
Are dispersedly provided so as to correspond to at least one or more of the back surface of the human foot. The fifth sheet 215 is coated with carbon in a part of the surface, that is, in the individual squares at the front, rear, left, and right with respect to the center, and the carbon forms the individual electrodes 215a to 215d of the foot switch. When the player steps on the fourth seat 2
The common electrode 213a of the third sheet 213 is electrically connected to at least one of the individual electrodes 215a to 215d of the fifth sheet 215 through the fourteen small holes 214a, 214a,. Small holes 214a, 21
The size of 4a,... Is set to such a size as not to be crushed and completely closed at the time of the stepping action of the player, for example, about 10 mm in diameter. Note that the positions of the small holes 214a, 214a,... May be dispersed so as to be uniform over the entire surface of the fourth sheet 214, depending on processing convenience. Thus, the common electrode 213a of the third sheet 213, the individual electrode 215a of the fourth sheet 214 and the fifth sheet 215
215d, foot switches are respectively formed at square positions (areas) corresponding to the four printed arrows.

EVA is used as the material of the sixth sheet 216 in order to withstand repeated repetition of the stepping action of the player and to have appropriate hardness to prevent plastic deformation of the foot switch. Further, a front electrode assembly for electrically connecting the common electrode 213a of the third sheet 213 and the four individual electrodes 215a to 215d of the fifth sheet 215 to the interface 20a of the game machine main body 100. The wiring is patterned and printed up to 217a, and the electrode assembly 217a has an electric wire cable 217b.
Is connected. At the tip of the electrode assembly 217a, FIG.
Is provided with a connection terminal portion 217c detachable from the interface 20a shown in FIG.

It should be noted that a game selection switch (other switch) can be additionally provided in addition to the four foot switches. In that case, the game selection switch is provided in a portion where the foot switch is not provided, for example, in two squares diagonally forward with respect to the center of the foot switch portion 210. Then, an appropriate mark indicating the position of the game selection switch (for example, a mark and a mark) is printed on the second sheet 212 at that position, and the small hole 2 is printed on the fourth sheet 214.
, And a fifth sheet 215
The individual electrodes 215e and 215f are formed on the substrate. These individual electrodes 215 e and 215 f and the third sheet 213
And the common electrode 213a form two game selection switches. There are also switches other than the foot switch and the game selection switch, for example, a start switch, a select switch, and the like, but these can be operated by the player while visually recognizing them, so that there is no need to identify them with feet. Therefore, there is no problem even if a plurality of such mats are provided on the same mat portion.

The mat section 220 is configured by combining nine (3 × 3) rectangular mat pieces (mat sections) slightly larger than the underside of the player's feet. As shown in FIG. 7, mat pieces 222 to 225 corresponding to the positions where the foot switches are formed are arranged in front, rear, left and right with a center piece 221 as one of the mat pieces as a center, and four mat pieces 226 to 225 in the remaining portion. 229 are arranged, and each is engaged via an engagement portion formed of an inverted wedge-shaped projection and a groove.

As shown in FIG. 8, the center piece 221 is formed such that only one of the engaging portions 221a of the four sides is different from the engaging portions 221b to 221c of the other three sides. This is because, among the four mat pieces 222 to 225 directly engaged with the center piece 221, the shape of the mat piece 222 arranged at the front is different from the other. That is, the mat piece 222 needs to be formed slightly longer by the amount of the electrode assembly 217a as described above, while the other mat pieces 223 are formed.
225 are the same shape, so that there is no problem even if the shape of the engaging portion is the same, sharing can be achieved, thereby facilitating the assembling work. Specifically, the engaging portion 221
The shape of the combination of the inverted wedge-shaped projection and groove shown in FIG. 7A is inverted from that of the other engagement portions 221b to 221d. The size of the protrusions and the grooves is determined to be appropriate so as to have strength enough to withstand repeated steps of the player.

The mat pieces 221 to 229 are all made of resin in order to obtain a soundproofing effect. Of these, the mat pieces 222 to 225 facing the foot switch are used.
Is made of a relatively soft sponge, polyethylene or the like. On the other hand, other mat pieces 226-
229 is made of relatively hard material such as EVA. By making each mat have a hardness difference depending on whether it is facing the foot switch or not, the player himself sinks into the mat to some extent when stepping on the grid position of the foot switch, but when stepping on other grid positions Because of the difference in the feeling that the foot switch does not sink, the user can easily recognize whether or not the foot switch is at the cell position without having to check the foot step by step during the game. The difference in hardness can be realized not only by the material but also by surface processing or shape, and also includes a difference in sinking amount when the player steps. For example, a substantial number of hemispherical convex bodies may be formed on the surface to give a foot a foreign-body sensation, thereby giving a substantial sense of hardness.

The foot switch section 210 is provided in the mat section 2
For example, as shown in FIG. 9, four points are fixed on the upper surface of the pad 20 by hook-and-loop fasteners 230 to prevent the two from shifting during the game. Alternatively, as shown in FIG. 10, the foot switch section 210 is attached to the upper surface of the mat section 220 by the hook-and-loop fastener 2.
30 and the other transparent sheet 240
, So that the displacement between the two hardly occurs. In this case, it is desirable that the mat section 220 be of an integral type in terms of manufacturing. However, even if it is a split type, it is possible to make it possible to engage the wrapped one as a unit. Further, a groove for preventing slip is formed on the surface of the sheet 240.

(Schematic Operation of Home Game System) Next, the schematic operation of the game system will be described with reference to FIG. A power switch (not shown) is turned on, and power is supplied to the game system. At this time, if the recording medium 30 is loaded in the recording medium driver 19,

The step position instruction data set by the rhythm setting unit 107 and read from the step position instruction data memory 105 for one set of data is replaced with image data (hereinafter referred to as a step position instruction mark) and temporarily stored in the mark memory 111. It is taken in. In this mark memory 111,
In the scroll display, two consecutive sets of data are written so that the image of the step position indication mark can always be displayed on the display surface of the monitor 12 without interruption. The scroll display control unit 110 sequentially writes the tread position indicating mark from the mark memory 111 as a scroll image in the buffer 11 (FIG. 2) so as to shift the read address at predetermined time intervals. In this way, in addition to the dance image which is not scrolled, the scrolling step position indicating mark is sequentially transferred to the buffer 11, and the contents of the buffer 11 are repeatedly repeated at a cycle of 1/60 second or the like by a known display scanning means. While being read out and displayed, a step position indication mark is scroll-displayed on the display surface of the monitor 12 and a dance image is displayed as a moving image as a background image.

FIG. 13 shows an example of a display screen of the monitor 12 (in the form of one set of data for four beats). In FIG. 13, a player plays a game on the foot switch device 200 and the dance image D is displayed. The background and the tread position indication marks M1 to M4 that sequentially scroll downward from the upper part of the screen at a predetermined speed are displayed in the order of M1, M4, M2, and M3.

Respectively. In the figure, the difficulty level of the dance image is relatively low.

The step operation monitoring unit 112 includes four foot switches 200 a to 200
This is to detect whether or not 200d has changed from off to on. The stepping action monitoring unit 112 processes the on points of the four foot switches 200a to 200d which are first turned on as detection data, and detects the on state of each foot switch in an identifiable manner.

(Game Operation) Next, the game operation of the present game system will be described with reference to the flow charts of FIG. 14 and FIGS.

FIG. 15 shows a main flowchart of the game operation. First, when the start button 22a of the controller 22 is detected to be on, a song name selection screen is displayed on the screen of the monitor 12 (step ST3). On this screen, for example, song names are displayed vertically and horizontally in a list, and when a desired song is selected from among them using the up key 22U or the like of the controller 22 or the game selection switch 200e of the foot switch device 200, the song title selection section is displayed. 10
3 reads out the performance data corresponding to the selected music title from the performance data memory 104, temporarily stores it in the buffer 14 (FIG. 2), and outputs it to the speaker 16 (step ST5). When the intro performance is started, a table having a rhythm of the number of beats corresponding to the selected music is designated from the step position indication data memory 105, and further a predetermined position of the table is set as the first two sets of data. For example, the step position instruction data having an intermediate level of difficulty is set, and the dance setting unit 109 sets a dance image of difficulty according to the rhythm and the difficulty of the set step position instruction data. (Step S
T7).

When one set of the first two sets of the step position indicating data is set, one set of the set data is overlapped on the background dance image D as shown in FIG. Display surface 3 as position indicating mark M
1 is scrolled up (step ST9). When the scroll display of each step position indication mark starts, a monitoring process is performed by the shift amount detection / integration unit 107 (step ST11). The monitoring process is performed in units of one set of data (step ST13). When a monitoring result for one set of data is transmitted to the rhythm setting unit 107, the rhythm setting unit 107 performs an evaluation based on the monitoring result (step S13).
T15).

Then, in response to the evaluation result, the next one set of data (that is, the third one set of data that is evaluated based on the monitoring result of the first one set of data) is set, and the set one is set. The dance image D corresponding to the set data is set (step ST17,
19). That is, the step position indicating mark for one set of data to be evaluated has already been scrolled out of the display surface 31, and the step position indicating mark based on the next one set of data is being scrolled displayed on the display surface 31. Therefore, one set of data set based on the evaluation result is set with one delay.

Next, it is determined whether or not the game has ended, that is, whether or not a predetermined time has elapsed since the start of the game, whether or not the performance of the selected music has ended, or whether or not a predetermined dance evaluation has been maintained at a certain level or higher. Is determined (step ST21). If the dance has not ended, the process returns to step ST9, where dance image D on display surface 31 is displayed.
The display of the step position indication mark M is continued, and the processing of steps ST9 to ST19 is sequentially repeated for each set data.

When it is determined that the game is over, the evaluation result for the dance of the player, which is the final content of the rhythm setting section 107, is displayed on the display surface 31 (step ST2).
3) The player is notified.

FIG. 16 is a flowchart showing a subroutine of the "monitoring process" in step ST11. In the figure, a variable i indicating the number of beats of one set of data is set to 1 (step ST31). The ON signal from 200d (FIG. 11) is detected, and ± time deviation from the actual stepping time with respect to the time when the mark M completely overlaps the stationary mark S is measured as deviation time data (step ST33).
In this measurement, the cycle of one beat is set by dividing the cycle by ± １ ／ cycle in the time direction (stroke direction of the mark M) with respect to the stationary mark S, and the mark M is stationary during the divided period. This is performed by measuring a time difference between the time point when the mark completely overlaps the mark S and the detected actual stepping time point. Since the time when the mark M completely matches the stationary mark S is obtained from the calculation for one beat, the on-state input from the stepping operation monitoring unit 111 on the condition that the corresponding stepping unit 13 is stepped on is set. Time lag data is obtained from the signal detection time. When the wrong footswitches 200a to 200d are stepped on, it may be treated as not being stepped on, or may be given a stricter negative evaluation, for example. Alternatively, the number of erroneous steps may be counted, and the game may be forcibly terminated when the number of steps reaches a predetermined number.

The interval between the timing shifted by １ ／ cycle and the timing when both marks M and S completely overlap is represented by, for example, converting it into 0 to 100 points (step ST35). For example, if an actual stepping action is performed at a time point shifted by 周期 cycle in any of the ± directions, 0 point is obtained.
If the actual stepping operation is performed when both marks M and S completely overlap, 100 points are given.

When the conversion of the score of the shift time data with respect to the mark M for one beat is completed, the variable i is incremented by 1 (step ST37), and it is determined whether or not the variable i is less than a predetermined number K (step ST37). ST39). The predetermined number K is 5 when one set data includes four beats,
When one set data consists of 8 beats, the value 9 is
The setting is made in accordance with the number of beats of the table selected in the step position indicating data memory 105. If the variable i is less than 5 as one set of data for four beats, step S
Returning to T33, a score is obtained for the next mark M in the same manner as described above. When the variable i becomes 5 (YES in step ST39), points for four beats have been obtained. Therefore, each score in the variables i = 1 to 4 is multiplied by a weighting coefficient to evaluate one set of data. (Step ST41). For example, since it is more difficult to take a rhythm on the second and fourth beats than on the first and third beats, the weighting factor is 12.5% for those scores on the first and third beats. 25 for the second beat
Multiplied by 50% for the fourth beat and 10%
A score out of 0 is scored. The weighting coefficient when one set of data is composed of eight beats may be appropriately allocated so as to be 100% as a whole. Further, a desired value can be set as the weighting coefficient, or the weighting coefficient is uniformly set to 25.
% (4 beats) or 12.5% (8 beats).

FIG. 17 is a flowchart showing a subroutine of the "evaluation process" in step ST15. In the figure, for the score obtained in step ST41,
It is determined whether it is large, medium, or small. Large is when the score is 80 to 100, medium is when the score is 21 to 79, and small is when the score is 0 to 20.

If the score is 20 points, one set data to be set next is set as the set data whose difficulty level is reduced by one rank with respect to the current rank (step ST53). The dance image D to be set is set so that the difficulty level is reduced by one rank from the current rank (step ST55). If the score is between 21 and 79, the data of the same rank as the current rank is set as the one set data to be set next (step ST57), and the dance image D to be set next is set.
Is set to the same difficulty as the current rank (step ST59). In both the step position instruction data table and the dance image D table, a plurality of types of data are stored for the same difficulty level. In the same rank data setting, different types of data are used. What is necessary is just to set it. For example, the degree of difficulty may be changed in the direction of the difficulty shown in FIGS. 12A and 12B within the range of the data of the same rank, or may be set randomly from within the same rank. On the other hand, if the score is 80 to 100 points, one set data to be set next is set with the difficulty increased by one rank with respect to the current rank (step ST61). The dance image D to be set is set so that the difficulty level is increased by one rank with respect to the current rank (step ST63).

When the process of setting the next step position instruction data and the dance image is completed, the current score is converted into an evaluation point (step ST65) and integrated with the evaluation point immediately before (step ST67).

FIGS. 14A and 14B are diagrams for explaining the evaluation points. FIG. 14A shows a state where the evaluation points have risen and is stable at a high level. FIG. 14B shows a state where the evaluation points have risen slightly. , Then shows a stable figure at a lower level. The horizontal axis represents the time width of one set of data, and the vertical axis represents the rank. The thin line represents the width of each rank from the highest rank S to the lowest rank D. The evaluation results are sequentially performed for each set of data as shown in FIG. 14, and the final evaluation can be obtained by integrating the evaluations at each time, so that the player's sense of rhythm and dance ability are effected on the player. It is possible to be notified.
