2. Related Art
After the infant child is born to contact the external world, the child is grown around games in the daily life and explores the unknown things by playing toys in the games to further know the external world and satisfy his/her own curiosity. During the growing process of the child, the toy is an indispensable medium in the games.
With the progress of the technology, the toys have been developed from the simple dolls and building blocks to the currently popular intelligent (wise) toy. Recently, nothing is better than the apparatus for interacting amusement in the popular electronic audio-visual game consoles. The so-called apparatus for interacting amusement outputs active behaviors from the apparatus. For example, the apparatus for interacting amusement may be an “electronic pet”, such as the well known eChicken, Furby, iDog and the like, early sold in the market. The “electronic pet” is a game console which actively operates in response to a user's command. In addition, the most popular apparatus for interacting amusement is the Wii game console available from Nintendo Company so that the player can interact with the image on the display through the real striking and waving and more fun of game may be obtained.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
FIG. 1 is a schematic illustration showing an apparatus for interacting amusement (also referred to as an interacting amusement apparatus) according to a preferred embodiment of the present invention. As shown in FIG. 1, a bear doll serves as an example of the apparatus for interacting amusement according to the embodiment of the present invention. This apparatus includes an acoustic receiver 101, a decoder 102 and an interaction generating apparatus. The interaction generating apparatus of this embodiment includes, for example, an interaction controller 103, a speaker 104, and hand/foot driving mechanisms 105, 106, 107 and 108.
FIG. 2 is a schematic illustration showing a system for interacting amusement according to a first embodiment of the present invention. Referring to FIG. 2, the system for interacting amusement includes the apparatus of FIG. 1 for interacting amusement, and further includes a television 201. More particularly, a high-frequency modulation signal is added to a portion of an acoustic wave in an external acoustic wave signal 202 emitted from the television 201. The high-frequency modulation signal is modulated to have the frequency, such as the frequency higher than 17 KHz, which cannot be or is hard to be recognized by the human ears. Thus, when the user is watching the television 201, it is hard for the user to realize or it is impossible for the user to realize the abnormal acoustic wave.
When the interacting amusement apparatus starts to operate, it receives the external acoustic wave signal 202 through its acoustic receiver 101. The acoustic receiver 101 transfers the external acoustic wave signal 202 into an acoustic signal AS. The decoder 102 receives the acoustic signal AS. If the acoustic signal has the high-frequency modulation signal, the decoder 102 decodes the high-frequency modulation signal into a complete packet message PGM according to a specific decoding procedure. The interaction controller 103 receives the complete packet message PGM, and controls the speaker 104 or/and the hand/foot driving mechanisms 105, 106, 107 and 108 to perform the designated operation according to the meanings represented by the complete packet message PGM. In order to describe the present invention more clearly, one example will be illustrated to show how the interacting amusement apparatus interacts with the television 201.
For example, the television 201 is connected to a digital multi-function optical disk player, and is playing a digital multi-function optical disk (DVD). The DVD is designed to work in conjunction with the interacting amusement apparatus. The user may hear the acoustic signal of “HELLO” when watching the television. Meanwhile, the interacting amusement apparatus also receives the acoustic signal of “HELLO”. According to the above-mentioned decoding procedure, the decoder 102 decodes to obtain the complete packet message PGM. The interaction controller 103 controls the speaker 104 to output the acoustic signal of “HELLO” according to the complete packet message PGM and controls the hand driving mechanism 105 to wave.
The above-mentioned embodiment is only a special example, and the application thereof is not limited to the process of outputting the acoustic wave of “HELLO” or waving the hand driving mechanism 105. If the control mechanism is perfectly designed, answering, dancing or the like may be performed according to the played acoustic signal. So, the present invention is not particularly restricted to the above-mentioned embodiment.
In addition, although the television 201 serves as an example of the external acoustic generating apparatus in the embodiment, those skilled in the art should understand that the external acoustic generating apparatus has many implementations. FIGS. 3 to 6 are schematic illustrations showing several systems for interacting amusement according to first to fourth embodiments of the present invention. As shown in FIG. 3, the external acoustic generating apparatus is a CD/DVD player 301. Next, as shown in FIG. 4, the external acoustic generating apparatus is a radio 401. In this example, the high-frequency modulation signal is modulated in the broadcasting program, and the acoustic signal of the broadcasting program is modulated by the frequency modulation (FM) or the amplitude modulation (AM), which are referred to as the dual modulation. Next, the external acoustic generating apparatus of FIG. 5 is a personal computer 501. The user can make the speaker of the computer play the modulated acoustic signal by way of network downloading or purchasing a CD or a DVD. In addition, what is special in this example is that an additional display panel 502 is added to the interacting amusement apparatus. In other words, the interacting amusement apparatus may interact with the external acoustic generating apparatus by displaying an image or images.
Finally, as shown in FIG. 6, the external acoustic generating apparatus of FIG. 6 is a public audio broadcasting apparatus 601. In addition, the interacting amusement apparatus of this example further includes an external large-scale display billboard 602, such as a large-scale electronic billboard in a baseball field. For example, when the batter hits a homerun, the high-frequency modulation signal may be added to the acoustic signal 202 when the broadcaster is broadcasting. When the acoustic receiver 101 of the interacting amusement apparatus receives the high-frequency modulation signal of the acoustic signal 202 and after the above-mentioned decoding, the interaction controller 103 can control the large-scale display billboard 602 to display the texts of “HOMERUN” and display a sparkler or the like.
In addition, the suitable modulation should be the frequency shift keying (FSK) modulation. In practice, the center frequency of the FSK modulation may be set to be 18 KHz, 17 KHz is set to be a binary digit 0, and 19 KHz is set to be a binary digit 1. Because the acoustic response of the human's ears on the acoustic signal higher than 17 KHz is not good, the human's ears cannot realize the modulation with the acoustic signal higher than 17 KHz. Although the embodiment is described with the frequency shift keying modulation, those skilled in the art should understand that the FSK modulation is only a non-restrictive example, and may easily adopt another modulation method, such as a phase shift keying modulation (PSK), a differential phase shift keying modulation (DPSK) or a minimum shift keying modulation (MSK).
FIG. 7 is a circuit block diagram showing the decoder 102 in the apparatus for interacting amusement according to the preferred embodiment of the present invention.
Referring to FIG. 7, the decoder 102 includes an analog-to-digital converter 701, a spectrum analyzer 702, a binary data decision circuit 703, a package header comparing circuit 704 and an error correcting circuit 705. The analog-to-digital converter 701 receives the acoustic signal AS and converts the acoustic signal AS into a digital signal DS. The spectrum analyzer 702 receives the digital signal DS, analyzes a frequency spectrum of the digital signal DS and then outputs a frequency envelope FE. The binary data decision circuit 703 receives the frequency envelope FE and a clock signal CK, and generates two-bit data BD according to the clock signal CK and the frequency envelope FE. The package header comparing circuit 704 compares the two-bit data BD with a predetermined packet header bit to extract the complete packet message PGM. The error correcting circuit 705 receives the complete packet message PGM and performs an error correction code calibration to ensure correct contents of the complete packet message PGM.
According to the above-mentioned embodiments, a method for interacting amusement may be concluded. FIG. 8 is a flow chart showing the method for interacting amusement according to the preferred embodiment of the present invention. Referring to FIG. 8, the method includes the following steps.
In step S801, the method starts.
