The audio unit 27 provides information about the comparison results in a voice and/or a sound. - Hereinafter, a dance training method according to the present invention will be described with reference to
FIGS. 1 to 3 .FIG. 3 is a flow diagram illustrating, the dance training method of the invention As shown inFIG. 3 theportable wireless terminal 20 executes the dance training program in step S31. The dance training program has various dance step information by item and by stage for learner's dance training and is stored in thesecond memory unit 24. According to a learner's input, thesecond control unit 23 loads and executes the dance training program stored in thesecond memory unit 24. - The dance training program preferably includes several menus such as a dance item selection, an exhibition dance preview, a partial dance exercise by stage, and a complete dance exercise, as shown in FIG. 4., which shows a sample output menu of the dance training program in accordance with the present invention. The dance item selection is a menu that allows a learner to select one of the available dance items. For example, such dance items may have a tap dance, a waltz, a tango, a cha-cha, a samba, a rumba, etc.
- An exhibition dance preview shows all actions of a learner's selecting dance in a moving image or animation format. Suitable background music is also preferably output to the preview the available dances.
FIG. 5 shows a sample exhibition dance preview of the dance training program. - The partial dance exercise, by stage, outputs step information of the dance selected by the learner, by stage. Following the step information in this menu, a learner can learn the selected dance by following each stage of the dance, as further described below.
FIG. 6 shows one stage of a sample selected the partial dance exercise of the dance training program. - The complete dance exercise is a menu for not only showing all actions of the selected dance in a moving image or an animation, but also continuously outputting the step information. Therefore a learner can try to perform the entire dance course. Additionally, this menu continuously displays the foot motion data of a learner as well as the step information, and allows for a final evaluation for the results of dance learning, As described below
FIG. 7 shows a sample portion of the complete dance exercise of the dance training program. - Returning to
FIGS. 1 to 3 , after the dance training program is executed, thesecond control unit 23 executes a menu of the partial dance exercise, by stage, on receipt of a learner's input in step S32. Then the step information about a learner's selected dance item is shown on thedisplay unit 26, as illustrated inFIG. 6 . The example provided inFIG. 6 utilizes images to show the location and direction of the learner's feet at a particular step of the selected dance item. - After executing the partial dance exercise, the
second control unit 23 transmits a request for sensing a learner's foot motion to the footmotion sensing module 10 in step S33. - On receipt of foot motion sensing request, the foot
motion sensing module 10 senses a learner's foot motion through thesensor unit 11 and calculates the foot motion data in step S34. In other words, a learner performs a dance according to the step information displayed on thedisplay unit 26, and thesensor unit 11 perceives a resultant foot motion. - For example, the
sensor unit 11 obtains data on a first step by sensing the location and the direction of a learner's foot while a performs presses the first step. Subsequently, thesensor unit 11 recognizes a next step from variations of sensing values when a learner performs a second step, and then calculates data on the second step by sensing the location and the direction of a learner's foot. Alternatively, thesensor unit 11 may sense the moving velocity of a learner's foot when a learner moves a foot to perform a second step. Then thesensor unit 11 may obtain the moving distance between the first and second steps by using the moving velocity, and also calculate data on the second step. - The
first control unit 12 transmits the foot motion data, which thesensor unit 11 senses and outputs, to theportable wireless terminal 20 through the first short-distancewireless communication unit 14 in step S35. At this time, the foot motion data may include the locations of both feet, the order of dance steps, the identification code of the footmotion sensing module 10, the directions of both feet, the moving distance, the count and tempo of the dance steps, etc. - The second short-distance
wireless communication unit 21 of theportable wireless terminal 20 receives the foot motion data transmitted by the footmotion sensing module 10. Then the footmotion perception unit 22 extracts the foot motion data from data the second short-distancewireless communication unit 21 receives. At this time, the footmotion perception unit 22 uses the identification code of the footmotion sensing module 10 when extracting the foot motion data. - After the foot motion data is extracted, the
comparator 23 a compares the foot motion data with the dance step information in step S36. Specifically, thecomparator 23 a receives the foot motion data from the footmotion perception unit 22 and reads the dance step information in thesecond memory unit 24. Then thecomparator 23 a compares the foot location of the foot motion data with that of the corresponding step information. If the result of comparison is the same location, the step is determined to be right. However, if different, the step is determined to be wrong. Thecomparator 23 a sends such judging data to theoutput units 26 and 27. When thecomparator 23 a determined whether the step is right or wrong, proper margins may be allowable. For example, if the foot locations are within a predetermined range, it may be determined to be the same step. In addition, the direction of the foot, together with the location, may be considered for comparison. - The
output units 26 and 27 output the results of step comparison thecomparator 23 a executes in step S37. The output will preferably simultaneously show the foot motion data and the step information in different image types on thedisplay unit 26. Making reference toFIG. 6 , the step information is displayed without color and the foot motion data is displaying in color, allowing each to be readily distinguished from each other. For the foot motion data, a black, a blue, and a red color will preferably represent a current step, a right step, and a wrong step, respectively. Preferred the output also shows the comparison results as a text on the display unit 26 (for example, seeFIG. 6 , ‘wrong step: No. 3’). Still another example of the output is to inform of the comparison results by using a sound or a voice output through the audio unit 27. - Next, the
second control unit 23 decides whether to end the dance training in step S38. Specifically, thesecond control unit 23 waits for a learner to terminate the dance training program currently being executed. If the termination an input is received, thesecond control unit 23 quits the dance training program and then preferably launches a start scene of the dance training program. If terminated input is not received, the aforementioned processes are repeated from step S32 with the repeated execution of the dance training program preferably returning to the same stage or the next stage of the dance exercise. - As discussed heretofore, a learner may execute the dance training program stored in the portable wireless terminal and then select a menu of the partial dance exercise, by stage. The terminal shows dance step information about a learner's selected stage on the display unit and waits for a learner's correspondence foot motion. The foot motion sensing module obtains foot motion data through the sensor unit and transmits the data to the terminal via a short-distance wireless communication unit. On receipt of the foot motion data, the terminal compares them data with the dance step information and outputs the results of comparison to a learner.
- Accordingly, the present invention may not only output information about dance steps, but also inform whether a learner successfully follows the dance steps. The present invention allows for practical and effective dance training and enables learners to easily and conveniently learn various dances. Furthermore, the present invention may reinforce the portable wireless terminal with applied functions and enhance its utility and competitiveness.
- While this invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, as defined by the appended claims.
