The foot pattern at the start shown in FIGS. 5 to 9, and the foot pattern image at the start (F0) corresponding to the foot pattern at the first step to the fourth step, and the first foot pattern image (F1) The data of the fourth foot image (F4) is created in advance and recorded in the computer 1. On the floor display device 2, the foot image (F0) at the start and the first foot image (F4) are recorded. The foot image (F1) to the fourth foot image (F4) are displayed in full screen. A creation method of the foot-shaped image (F0) data at the start and the first foot-shaped image (F1) data to the fourth foot-shaped image (F4) data will be described later.

  Table 1 is an example of control data corresponding to the foot diagram shown in FIG. 4, and FIG. 10 is a timing chart showing the timing at which the computer 1 transmits foot image (F0 to F4) data to the controller 3. . In Table 1, the display time T of each step is determined in accordance with the slowness C of each corresponding step.

First, when the practitioner operates the operation unit 15 to instruct the computer 1 to select a desired type of dance, the computer 1 transmits the foot-shaped image (F0) data at the start to the controller 3 to display the floor surface. The device 2 displays the foot image (F0) at the start. Specifically, as shown in FIG. 5, the foot molds 31 </ b> L and 31 </ b> R of the left and right feet at the start are displayed on the floor display device 2.

  Next, when the practitioner operates the operation unit 15 to instruct the computer 1 to start practice, that is, when the start signal S is transmitted from the operation unit 15 to the computer 1, the computer 1 outputs the start signal S. After a predetermined waiting time (for example, 1000 milliseconds) recorded as data in advance in the computer 1 from the received time, the first foot-shaped image (F1) data is transmitted to the controller 3, and the floor display device 2 Displays the first foot-shaped image (F1). Specifically, as shown in FIG. 6, the foot pattern 31 a of the first step and the foot pattern 31 R of the right foot at the start are displayed on the floor display device 2. Here, the character “1” and the character “S” are displayed as the step character 32 and the count character 33 on the inner side of the foot pattern 31a, and the practitioner is shown to step “slowly” on the “first” step. .

  Next, the computer 1 receives the second foot-shaped image (F2) data after 600 milliseconds designated as the display time T in the first step from the time when the first foot-shaped image (F1) data is transmitted. Is transmitted to the controller 3, and the floor display device 2 displays the second foot image (F2). In this way, the first foot image (F1) is displayed for 600 milliseconds until the second foot image (F2) is displayed. Specifically, as shown in FIG. 7, on the floor display device 2, a footstep 31b of the second step and a footstep 31a of the first step are displayed. Here, the character “2” and the character “S” are displayed as the step character 32 and the count character 33 on the inner side of the foot shape 31b, and the practitioner is shown to take the “second” step “slowly”. . The characters “1” and “S” displayed on the inner side of the foot mold 31a in the first step are not displayed in the second step.

  Next, the computer 1 transmits the third foot-shaped image (F3) data after 600 milliseconds specified as the display time T in the second step from the time when the second foot-shaped image (F2) data is transmitted. Is transmitted to the controller 3, and the floor display device 2 displays the third foot image (F3). As described above, the second foot image (F2) is displayed for 600 milliseconds until the third foot image (F3) is displayed. Specifically, as shown in FIG. 8, on the floor display device 2, a footstep 31c of the third step and a footstep 31b of the second step are displayed. Here, the character “3” and the character “Q” are displayed as the step character 32 and the count character 33 on the inner side of the footprint 31c, and the practitioner is shown to take the “third” step “fast”. . The characters “2” and “S” displayed on the inner side of the foot mold 31b in the second step are not displayed in the third step.

  Next, the computer 1 transmits the fourth foot image (F4) data after 300 milliseconds designated as the display time T in the third step from the time when the third foot image (F3) data is transmitted. Is transmitted to the controller 3, and the floor surface display device 2 displays the fourth foot image (F4). In this way, the third foot image (F3) is displayed for 300 milliseconds until the fourth foot image (F4) is displayed. Specifically, as shown in FIG. 9, the footstep 31 d of the fourth step and the footstep 31 c of the third step are displayed on the floor display device 2. Here, the character “4” and the character “Q” are displayed as the step character 32 and the count character 33 inside the footprint 31d, and the practitioner is shown to take the “fourth” step “fast”. . The character “3” and the character “Q” displayed inside the foot mold 31c in the third step are not displayed in the fourth step.

  Further, as shown in FIG. 10, the fourth foot image (F4) is displayed next in the fourth foot image (F4) as in the case of the third foot image (F3). It is displayed for 300 milliseconds until an image to be displayed is displayed.

  In this way, the foot pattern is displayed with the step character 32 and the count character 33 at the position where the foot should be placed in each step. The step character 32 and the count character 33 are displayed only for a period corresponding to the speed at which the step should be carried, and the step character 32 and the count character 33 are not displayed on the foot corresponding to the foot that does not move. Thereby, the practitioner can correctly understand the order of steps and the count of steps, and can prevent the practitioner from misidentifying the order of steps and the speed.

  In the following, based on the data shown in Table 1, the foot-shaped image (F0) data at the start and the first foot-shaped image (F1) data for displaying the footprints shown in FIGS. An example of a method for creating the fourth foot image (F4) data will be described. In the following description, a program having an image composition function, background image data, left foot foot image data (FL), right foot foot image data (FR), step character image data, and count character data It is assumed that the image data is recorded in the computer 1 in advance. Unless otherwise specified, background image data, left foot foot image data (FL), right foot foot image data (FR), step character image data and count character image data are each foot shape. Each time image (F0 to F4) data is created, the intermediate composite image data that is newly read from the recording unit 13 into the memory 12 and temporarily used for the synthesis of the image data is the foot image (F0 to F4) data. Is erased from the memory 12 each time the creation of each is completed.

  FIG. 11 is an enlarged plan view of region IV in FIG. As shown in FIG. 11, in the method for creating the foot image (F0 to F1) according to the present embodiment, for example, the image data (FR) of the right foot or the image data (FR) of the right foot is added to the data of the white background image. Foot-shaped image data (FL) (hereinafter referred to as partial foot-shaped image data) is rotated by a rotation amount R and synthesized at the position indicated by coordinates (X, Y) to create a foot-shaped image To do. The coordinates (X, Y) are the coordinates of the center of gravity G of the partial foot image when the lower right end of the floor display device 2 is used as a reference (origin). The rotation amount R is a clockwise rotation angle (degree) of the long axis passing through the center of gravity of the partial foot type image with respect to the Y axis.

  First, with reference to FIG. 5, a method of creating the foot-shaped image (F0) data at the start will be described. As shown in FIG. 5, at the start, the left and right foot molds are displayed. For this reason, as shown in Table 1, the control data includes two sets of data corresponding to the step order n = 0 (both left and right feet), and these are identified by the left / right distinction M of the step. Further, when creating the foot-shaped image (F0) data at the start time, the data of the step C and the foot-shaped image display time T are unnecessary. Therefore, as shown in Table 1, the character string “NULL”, which means that there is no value, is set in the step steepness C and the foot-shaped image display time T in the two data corresponding to n = 0. ing.

  First, with reference to the control data corresponding to the step order n = 0 and the left / right distinction M = L of the step, the foot image data of the left foot corresponding to the left / right distinction M = L of the step (see FIG. FL) is rotated by a rotation amount R = 340 degrees, and is synthesized at a position corresponding to the foot-shaped image display position (X, Y) = (50, 40) to create a first intermediate composite image To do. Next, referring to the control data corresponding to n = 0 and M = R, the right foot-shaped image data (FR) corresponding to M = R is further added to the first intermediate composite image as R = 340. It is rotated by a degree and is synthesized at a position corresponding to (X, Y) = (40, 50) to create the foot-shaped image (F0) data at the start.

  Next, a method for creating the first foot image (F1) data will be described with reference to FIG. First, in the first step, the image data of the step character “1” corresponding to n = 1 and the step speed C are shown in order to show that the foot corresponding to n = 1 means the first step. The image data of the count character “S” corresponding to “= S” is synthesized with the foot-shaped image data (FL) of the left foot corresponding to “M = L” to create a first intermediate composite image. Next, referring to the control data corresponding to n = 1, the image data of the first intermediate composite image is rotated by R = 340 degrees to the background image data, and (X, Y) = (75 , 90) to generate a second intermediate composite image. Next, since the first step is the left foot indicated by M = L, control of the right foot indicated by M = R among the data for both the left and right feet corresponding to n = 0 indicating the foot shape at the start. Based on the data, foot image data is synthesized. That is, referring to control data corresponding to n = 0 and M = R, right foot-shaped image data (FR) corresponding to M = R is further added to the second intermediate composite image, and R = 340 degrees. And the first foot image (F1) data is created by combining the positions corresponding to (X, Y) = (40, 50).

  Next, with reference to FIG. 7, a method for creating the second foot image (F2) data will be described. First, in the second step, the image data of the step character “2” corresponding to n = 2 and C = S are set to indicate that the foot corresponding to n = 2 meaning the second step is carried. The image data of the corresponding count character “S” is combined with the right foot foot image data (FR) corresponding to M = R to create a first intermediate composite image. Next, referring to the control data corresponding to n = 2, the image data of the first intermediate composite image is rotated by R = 340 degrees to the background image data, and (X, Y) = (85 , 150) to create a second intermediate composite image. Next, referring to the control data corresponding to n = 1, the left foot-shaped image data (FL) corresponding to M = L is further rotated by R = 340 degrees in addition to the second intermediate composite image. Then, the second foot-shaped image (F2) data is created by combining the positions (X, Y) = (75, 90).

  Thereafter, the third foot-shaped image (F3) data is referred to the control data corresponding to n = 3 and the control data corresponding to n = 2 by the same creation method as the second foot-shaped image (F2). The fourth foot-shaped image (F4) data is created by referring to the control data corresponding to n = 4 and the control data corresponding to n = 3.

  Next, a function for synchronizing and displaying the image of the dance that has actually danced and the foot shape will be described. FIG. 12 is a perspective view showing a state in which the dance practice device according to the embodiment of the present invention is installed.

  As shown in FIG. 12, a floor display device 2 for displaying a foot shape is disposed on the floor, and a display device 6 having speakers 4 at both ends is disposed at the height of the eyes of the practitioner in front of the dance practice device. Has been. A plurality of photographing devices 5 are arranged in four directions around the dance practice device. While the floor display device 2 displays a series of foot shapes corresponding to the type of dance selected by the practitioner, the speaker 4 outputs dance music having a predetermined rhythm corresponding to the type of dance, and the display device 6. Displays a video corresponding to the type of dance, for example, a dance video corresponding to the selected type of dance.

  The photographing device 5 photographs the dance and records the photographed video, that is, moving image data, in the computer 1. The recorded moving image data is read from the recording unit 13 and displayed on the display device 6. For example, using the photographing device 5, a dance by an instructor is photographed in advance and recorded in the computer 1, and the recorded dance video is displayed on the display device 6. Further, the position and timing of a series of steps by the instructor are detected by the touch panel 24, and the detected position data and step timing (for example, time information) are used as the foot-shaped image display position (X, Y) and The display time T of the foot-shaped image is recorded in the computer 1 in advance, and is displayed on the floor display device 2 together with the dance video by the instructor described above. At this time, as the rotation amount R data necessary for displaying the foot-shaped image, data on the rotation amount R of the same dance step as the instructor dances recorded in advance in the computer 1 is used. Alternatively, the computer 1 detects a stepped area using the touch panel 24 and creates foot-shaped image data, and the computer 1 determines the long axis and the short axis of the foot shape in the obtained image data. By detecting, data of the rotation amount R is calculated. As a result, the practitioner checks the dance image by the instructor displayed on the display device 6 in front of the eyes and the foot pattern displayed on the floor display device 2 below the feet while synchronizing with the dance image. Can be practiced efficiently. In order to display the dance video and the foot-shaped pattern in synchronization, the computer records the time information represented by the start signal S when recording the captured dance video and when recording the timing of the detected step. 1 may be recorded. Accordingly, the computer 1 can display the dance video and the foot pattern in synchronization with each other based on the start signal S.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to said embodiment.

  For example, in the above description, a case has been described in which a series of foot-shaped images to be displayed is generated in advance and these are sequentially displayed at a specified timing. However, even if a foot-shaped image is generated in real time according to a specified timing, Good. For example, at each timing determined by the display time T in Table 1, processing corresponding to each timing is performed among the above-described methods for creating a foot image, and corresponding foot image data is created. May be. When all the foot-shaped image data of a dance is recorded in advance, it is necessary to equip a large-capacity recording means in order to cope with various kinds of dances. However, if only control information as shown in Table 1 and relatively small partial images of the right foot and left foot are recorded and foot image data is generated in real time, a relatively small capacity recording means can be used. More types of foot-shaped image data of dance can be displayed.

  Also, in the above embodiment, the explanation was given using “Blues” Quarter Turns, but the type of dance is not limited to this, other items of social dance such as tango and waltz, hip hop, flamenco or Other types of dance such as hula dance may be used.

  In the above embodiment, the character “S” or “Q” is used as the count character 33 indicating the speed of the step, but any figure (including letters and numbers) is used as the count character 33. Can be changed as appropriate according to the type of dance. For example, an alphabet other than “S” and “Q”, a combination of numbers, alphabets and figures, for example, a character surrounded by a circle, an arbitrary character or symbol such as a midpoint “·” and an ampersand “&” is used. be able to.

  Further, in each step, the step character 32 and the count character 33 are not limited to the case where the step character 32 and the count character 33 are attached to only one of the footprints with movement, and the step character 32 and the count character 33 attached to the foot pattern without the movement are included. You may leave without erasing.

  Further, in the above embodiment, the foot shape in the case of one practitioner is displayed, but the foot shape in the case of two practitioners, for example, the foot shape for a male and a female foot shape for ballroom dance And may be displayed simultaneously. In this case, for example, in order to distinguish between a foot pattern for men and a foot pattern for women, for example, a foot pattern image of a female step is different from a foot pattern image of a male step (for example, a heel). The corresponding portion may be displayed in a foot shape with a small circle). Alternatively, for example, the foot pattern image for men may be displayed in blue, the foot pattern image for women may be displayed in red, and the foot pattern for men and the foot pattern for women may be displayed in different colors.

  Moreover, in the said embodiment, although the distance between the footprints of the footprint diagram displayed on the floor-surface display apparatus 2 and the magnitude | size of each footprint | foot_shape are fixed, these values are made into an exerciser's Depending on the extension, the display may be changed depending on whether the trainee is an adult or a child. For example, when the practitioner is a child, the foot position image display position (X, Y) is obtained by multiplying the coordinate values X and Y by a child coordinate scaling value α (0 <α <1). A foot image (F0 to F1) may be created as coordinates, that is, coordinates represented by (α × X, α × Y). At this time, the right and left foot image data (FR) and left foot image data (FL) to be combined with the background image data are also reduced by multiplying the vertical and horizontal sizes of the image by α. Is desirable. Thereby, when the practitioner is a child, the distance between the foot forms and the size of each foot form can be reduced and displayed on the floor display device 2 as compared with the case of an adult.

  Moreover, in the said embodiment, although the display timing of the footprint figure displayed on the floor display apparatus 2 is being fixed, you may change according to a practitioner's liking and skill level. For example, as described above, when the display timing is changed between the case where the practitioner is an adult and the case where the practitioner is a child, the time scaling value β (β> 1) for the child is added to the display time T of the foot-shaped image. The foot images (F0 to F4) may be displayed as the multiplied time, that is, the time represented by β × T. Thereby, when the practitioner is a child, the foot-shaped images (F0 to F4) can be displayed on the floor display device 2 at longer time intervals than in the case of an adult. Further, in order to change the timing for displaying the foot image according to the practitioner, the scaling value β may be specified to the computer 1 by operating the operation unit 15. In addition, the above-mentioned method for generating the foot-shaped image data in real time creates foot-shaped image data for children, scales the foot-shaped image data according to the height of the practitioner, It can also be applied to the case of displaying at a timing according to the degree.

  Moreover, in the said embodiment, although the step character 32 and the count character 33 were attached | subjected to the foot type | mold and it displayed on the floor surface display apparatus 2, the arrow 34 which means step sending according to a practitioner's selection is displayed. You may display on the floor surface display apparatus 2. FIG. By displaying the arrow 34, the practitioner can more intuitively understand the movement of the foot between steps.

  In the above embodiment, the dance video being practiced is photographed and the photographed dance video is displayed on the display device 6 in front of the practitioner. However, the video displayed on the display device 6 is the actual dance video itself. For example, a dance video is created by synthesizing, for example, images of forests, beaches, and the moon, which have been recorded on the computer 1 in advance, with the background of the shot dance video, and is displayed on the display device 6. It may be displayed. Thereby, a favorite image is synthesized with the background of the dancer's own dance video, and the amusement of the dance practice device can be enhanced.
