Therefore, the conventional dance game system is large and hard to carry about, and the sites for playing a dance game are limited. Besides, when two persons play the dance game at the same time, they both face the display units 11 with the result that users lack interaction between them. As the users have to use the dance pads 12 to input signals, dance activities are limited to inside the dance pads 12. Further, the dance pads 12 may slip and cause safety concern of the players.
  • Accordingly, how to solve the above-mentioned problems of the conventional dance game system is highly desirable.

  • The objective, technologies, features and advantages of the present invention will become apparent from the following description in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of the present invention.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • The foregoing conceptions and their accompanying advantages of this invention will become more readily appreciated after being better understood by referring to the following detailed description, in conjunction with the accompanying drawings, wherein:
  • FIG. 1 is a diagram schematically illustrating the operation of a conventional dance game system;
  • FIG. 2 is a block diagram schematically illustrating a dance game system according to an embodiment of the present invention; and
  • FIG. 3 is a diagram schematically illustrating the host appearance of a dance game system according to an embodiment of the present invention.
    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIG. 2 illustrates a dance game system. In one embodiment, a dance game system 2 comprises a host 21 and a motion sensor 22. The host 21 comprises a data inputting interface 218, an audio outputting unit 212, a prompting unit 211, a control unit 215, a first transceiver 217, a user interface 214 and a power supply unit 216. The data inputting interface 218 communicates with a storage medium 3. The storage medium 3 stores at least one audio signal AS and at least one prompting signal PS. For example, the storage medium 3 is a memory card or a game cartridge. The audio outputting unit 212 outputs audio signals AS. The prompting unit 211 prompts step directions to users.
  • The control unit 215 is electrically coupled to the data inputting interface 218, the audio outputting unit 212, and the prompting unit 211. The control unit 215 receives audio signals AS and prompting signals PS from the storage medium 3 via the data inputting interface 218. Then, the control unit 218 transmits the audio signals AS to the audio outputting unit 212, and the audio outputting unit 212 outputs the audio signals AS. The control unit 218 controls the prompting unit 211 according to the prompting signals PS. For example, the audio outputting unit 212 is a built-in speaker or an external speaker, and the prompting unit 211 includes a plurality of LEDs (Light Emitting Diode), and the LEDs are respectively arranged in 4-8 different directions to prompt dance step directions to a user, as shown in FIG. 3.
  • The first transceiver 217 receives a step signal StS, and the control unit 215 determines whether or not the step of a user is correct according to the step signal StS. The user uses the user interface 214 to operate the host 21. For example, the user interface 214 comprises a plurality of buttons 2141 and a built-in display unit 2142, as shown in FIG. 3. The display unit 2142 is only intended to present brief information, such as repertoire, score, elapsed time, consumed calories, etc. Therefore, the display unit 2142 can be miniaturized. The power supply unit 216 provides power for the host 21.
  • The motion sensor 22 is worn on two feet of a user. The motion sensor 22 detects the motions of the feet and transmits the motion signals to the host 21. The motion sensor 22 comprises an acceleration sensor 223, a processing unit 222, a second transceiver 221 and a battery module 224. The acceleration sensor 223 senses the motions of the feet and outputs a sensation signal SeS. For example, the acceleration sensor 223 is a two-axis or three-axis acceleration sensor. It should be particularly mentioned that the acceleration sensor 223 not only can sense the motions of two feet toward 4-8 different directions but also can detect the motions of standing on toes, standing on heels, revolving, bouncing, etc.
  • The processing unit 222 is electrically coupled to the acceleration sensor 223. The processing unit 222 processes sensation signals SeS and outputs step signals StS. The second transceiver 221 is electrically coupled to the processing unit 222 to receive step signals StS and then sends out the step signals StS. The battery module 224 provides power for the motion sensor 22.
  • In one embodiment, a communication frequency of the second transceiver 221 and the first transceiver 217 may be an ISM band (Industrial Scientific Medical band), such as 27 MHz or 2.4 GHz, and the second transceiver 221 and the first transceiver 217 may be two-way transmission. For example, each of the second transceiver 221 and the first transceiver 217 may be a Bluetooth module or a WLAN (Wireless Local Area Network) module. The power supply unit 216 may be a rechargeable battery, a disposable battery or an external power source. The battery module 224 may be a rechargeable battery or a disposable battery.
  • In the abovementioned structure, the control unit 215 of the host 21 receives audio signals AS and prompting signals PS. The audio signals AS include music, voice, sound effects and a combination thereof. The control unit 215 controls the audio outputting unit 212 to output the audio signals AS for users. According to the predetermined prompting signals PS, the control unit 215 controls the indicators of the prompting unit 211, and the user moves his feet according to the indicators. For example, the user moves his feet forward, backward, left, right, upper left, lower left, upper right, or lower right according to the indicators. According to another example, the user stands on toes, stands on heels, revolves or bounces according to the indicators.
  • Further, the motion sensor 22 worn on the feet converts the foot motions responding to the indicators into step signals StS and returns the step signals StS to the host 21. The control unit 215 evaluates the foot motions of the user according to the feedback step signals StS and responds to the foot motions via controlling the audio outputting unit 212 to make voices (such as GREAT, GOOD, BAD, etc.) or sound effects.
  • Referring to FIG. 2, the host 21 of the dance game system 2 further comprises a communicating port 213 electrically coupled to the control unit 215, and the host 21 can exchange data with another host 21′ via the communication port 213. Inserting the storage medium 3 into the host 21 or the host 21′ enables more than two persons to play dance game simultaneously. In one embodiment, the communicating port 213 is a wired or wireless communicating port.
  • In conclusion, the dance game system of the present invention does not use a larger-size and complicated display unit, instead adopts indicators to prompt step directions. Therefore, the present invention can realize a miniaturized dance game system which is not limited by the space. The present invention does not use the conventional dance pads, instead adopts an acceleration sensor to detect dance steps and transmits the results to the host wirelessly. Therefore, the operation area of the dance game system is not limited by the dance pads, and the safety concern of the users caused by slippery dance pads may be avoided. Further, when using the present invention, users needn't face conventional display units, such as televisions, but can arbitrarily arrange the portable dance game systems. For example, the users can play the dance game systems of the present invention by facing to each other. Therefore, the users can have better interaction while using the present invention.
  • The embodiments described above are intended to demonstrate the technics and features of the present invention to enable the persons skilled in the art to understand, make, and practice the present invention. However, it is not intended to limit the scope of the present invention. Any equivalent modification or variation according to the spirit of the present invention shall also be construed to be within the scope of the present invention.
