When the player waves the pointer, the game peripheral apparatus can capture a plurality of images per second. That is, the motion tracking sensor senses sequential spots of the moving infrared ray. Therefore, the game peripheral apparatus compares the coordinates of the spots in each of the images with each other to instruct the game host to change the position of the cursor or the object that displays on the screen of the television. Such a conventional game peripheral apparatus and game host cannot achieve the communication of considerable data between them. That is, the transmission of the infrared ray practically cannot satisfy the requirement of the very high baud rate. Moreover, the manipulation challenges this game peripheral apparatus.
  • As a result, the conventional game peripheral apparatus and game host cannot meet the requirement of the player for handy control.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • A UWB system uses a frequency band with an extreme wide bandwidth for wireless communication through pulse signal transmission technology. Instead of continuous sine waves, such a system speedily generates pulse signals through a time modulation method so that a very high data flow rate is carried on the extreme wide band.
  • As shown in FIG. 3, a UWB system 32 has the ratio of its bandwidth to its central frequency larger than 25%. The American Federal Communications Commission (FCC) has approved regulations releasing a band between 3.1-10.6 GHz for the free use of the UWB system. For example, the central frequency of UWB signals is at 4 GHz, and its corresponding bandwidth is larger than 1 GHz. Because each of the pulse signals has a very short period in a time domain, a very wide bandwidth occurs on a frequency domain. Excluding the pulse signals spread in a single band, they can also be spread in a plurality of bands through a multi-band processing. That is, the whole bandwidth of the UWB is divided into a plurality of narrow bands so that the narrow bands are simultaneously distributed on the spectrum of the UWB system.
  • Shannon proposes that the maximal channel capacity formula is in the form of:

  • Transmission Rate=Utilized Bandwidth×log2(S/N);
  • where S is signal power and N is noise power.
  • The transmission rate is linearly increased depending on the increase of the utilized bandwidth. Therefore, the UWB system has a very high transmission rate of 480 Mbps. It is superior to the transmission rate of an infrared communication or Bluetooth communication with a narrow band (721 kbps-1 Mbps).
  • FIG. 4 is a schematic diagram of an interactive wireless game apparatus in accordance with a first embodiment of the present invention. An interactive wireless game apparatus 44 comprises a wireless USB interface module 43, a game host 42 and a game peripheral apparatus 41. A wireless peripheral module 40 comprises the wireless USB interface module 43 and the game peripheral apparatus 41. Furthermore, the wireless USB interface module 43 is detachable from the game host 42. The game host 42 utilizes a multimedia processing module or a program to execute game software, and has interactive actions with a player who manipulates the game peripheral apparatus 41 through the wireless USB interface module 43.
  • Furthermore, the wireless USB interface module 43 is a plug-in for a personal computer 42′ to execute the play program. The game peripheral apparatus 41 employs an image sensor 411 to capture specified motion signals or instruction image signals such as trajectory images tracking the movement of a light spot generator device held by the player. An image preprocessing unit 412 can modulate and modify the images captured by the image sensor 411. For example, the luminance and chroma of the images are altered, or a specified image adjustment result is achieved by performing image data calculation and image compression.
  • The image sensor 411 and image preprocessing unit 412 can be integrated into an IC to form a system on chip (SOC). A data processing unit 413 converts the data after image processing into compressed signals with different formats. That is, the image data are converted into signals that comply with the protocol of the UWB system. The motion signals detected by the image sensor 411 are digitalized and transmitted to a transmitter/receiver unit 414. Because the transmitter/receiver unit 414 is compatible with the aforesaid UWB system, it can utilize an ultra wide band to transmit a very large data flow. In comparison with conventional systems, the present invention has advantages of high transmission rate and wireless convenience. Furthermore, a universal asynchronous receiver transmitter (UART) interface (not shown) is placed between the image preprocessing unit 412 and data processing unit 413.
  • The transmitter/receiver unit 414 wirelessly communicates with the transmitter/receiver unit 433 of the wireless USB interface module 43 through series signals, and wireless signals are received and emitted by antennas 415 and 434. The wireless USB interface module 43 is compatible with the protocol of the IEEE802.15.3 and USB so that it can communicate with at least one game peripheral apparatus 41 through transmitting and receiving wireless signals. In some cases, it can simultaneously communicate with up to 127 sets of the game peripheral apparatuses 41 by utilizing a working frequency band ranging from 3.1 GHz-10.6 GHz. To prevent interference with the band at 5 GHz which is authorized to IEEE 802.11a, the wireless USB interface module 43 reduces the emitting power to 75 nW/MHz. Giving an example of the application of IEEE802.15.3a, the transmission rate is 480 Mbps at most. In this case, the emitting power is adjusted to 0.2 mW to prevent interference with the utilized bands, and the corresponding effective transmission distance is ten meters or more.
  • The wireless USB interface module 43 applies multiband orthogonal frequency division multiplexing technique to modulate signals, and the band ranging from 3.1 GHz to 10.6 GHz is divided into 13 sub-bands of which each has a bandwidth of 528 MHz. Each sub-band employs 128 sub-carriers. Furthermore, 100 of the sub-carriers are specially modulated by quadrature phase shift keying (QPSK) technique for data transmission. The data transmission rate for the wireless USB interface module 43 is adjustable; for example 55 Mbps, 80 Mps, 110 Mbps, 200 Mbps, 320 Mbps and 480 Mbps. In addition, wireless USB (WUSB) technique proposed by Intel on 2005 is also applicable to the wireless USB interface module 43 so that it can similarly transmit and receive wireless signals compatible with the USB protocol.
  • The wireless USB interface module 43 has a USB control unit 431 bidirectionally communicating with either the game host 42 or the personal computer 42′, and further has a data conversion unit 432 to convert UWB signals to USB signals and convert USB signals to UWB signals.
  • FIG. 5 is a schematic diagram of an interactive wireless game apparatus in accordance with a second embodiment of the present invention. In contrast with FIG. 4, the wireless USB interface module 43 is integrated into a game host 52. The game host 52 comprises a multimedia processing module 521 executing the game program. The wireless USB interface module 43 transmits the received wireless signals to the multimedia processing module 521 for processing. The game host 52 and the game peripheral apparatus 41 make up an interactive wireless game apparatus 50.
  • The aforementioned descriptions of the present invention are intended to be illustrative only. Numerous alternative methods may be devised by persons skilled in the art without departing from the scope of the following claims.
