     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following description is of the best presently contemplated mode of carrying out the present invention. This description is not to be taken in a limiting sense but is made merely for the purpose of describing the general principles of the invention. The scope of the invention should be determined by referencing the appended claims. 
       FIG. 1  is a simplified block diagram of the communication device  200  utilized in the present invention. In  FIG. 1  communication device  200  includes CPU  211  which controls and administers the overall function and operation of communication device  200 . CPU  211  uses RAM  206  to temporarily store data and/or to perform calculation to perform its function. Video processor  202  generates analog and/or digital video signals which are displayed on LCD  201 . ROM  207  stores data and programs which are essential to operate communication device  200 . Wireless signals are received by antenna  218  and processed by signal processor  208 . Input signals are input by input device  210 , such as dial pad, and the signal is transferred via input interface  209  and data bus  203  to CPU  211 . Indicator  212  is an LED lamp which is designed to output different colors (e.g., red, blue, green, etc). Analog audio data is input to microphone  215 . A/D  213  converts the analog audio data into a digital format. Speaker  216  outputs analog audio data which is converted into an analog format by D/A  204 . Sound processor  205  produces digital audio signals that are transferred to D/A  204  and also processes the digital audio signals transferred from A/D  213 . CCD unit  214  captures video image which is stored in RAM  206  in a digital format. Vibrator  217  vibrates the entire device by the command from CPU  211 . 
       FIG. 2   a  illustrates one of the preferred methods of the communication between two communication devices. In  FIG. 2   a  both device A and device B represents communication device  200  in  FIG. 1 . Device A transfers wireless data to transmitter  301  which relays the data to host  303  via cable  302 . The data is transferred to transmitter  308  (e.g., a satellite dish) via cable  320  and then to artificial satellite  304 . Artificial satellite  304  transfers the data to transmitter  309  which transfers the data to host  305  via cable  321 . The data is then transferred to transmitter  307  via cable  306  and to device B in a wireless format. 
       FIG. 2   b  illustrates another preferred method of the communication between two communication devices. In this example device A directly transfers the wireless data to host  310 , an artificial satellite, which transfers the data directly to device B. 
       FIG. 2   c  illustrates another preferred method of the communication between two communication devices. In this example device A transfers wireless data to transmitter  312 , an artificial satellite, which relays the data to host  313 , which is also an artificial satellite, in a wireless format. The data is transferred to transmitter  314 , an artificial satellite, which relays the data to device B in a wireless format. 
     Voice Recognition 
     Communication device  200  has a function to operate the device by the user&#39;s voice or convert the user&#39;s voice into a text format (i.e., voice recognition). The voice recognition function can be performed in terms of software by using area  261 , the voice recognition working area, of RAM  206  ( FIG. 1 ) which is specifically allocated to perform such function as described in  FIG. 3 , or can also be performed in terms of hardware circuit where such space is specifically allocated in area  282  of sound processor  205  ( FIG. 1 ) for the voice recognition system as described in  FIG. 4 . 
       FIG. 5  illustrates how the voice recognition function is activated. CPU  211  ( FIG. 1 ) periodically checks the input status of input device  210  ( FIG. 1 ) (S 1 ). If the CPU  211  detects a specific signal input from input device  210  (S 2 ) the voice recognition system which is described in  FIG. 2  and/or  FIG. 3  is activated. 
     Voice Recognition—Dialing/Auto-Off During Call 
       FIG. 6   a  and  FIG. 6   b  illustrate the operation of the voice recognition in the present invention. Once the voice recognition system is activated (S 1 ) the analog audio data is input from microphone  215  ( FIG. 1 ) (S 2 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 3 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) to retrieve the text and numeric information therefrom (S 4 ). Then the numeric information is retrieved (S 5 ) and displayed on LCD  201  ( FIG. 1 ) (S 6 ). If the retrieved numeric information is not correct (S 7 ) the user can input the correct numeric information manually by using input device  210  ( FIG. 1 ) (S 8 ). Once the sequence of inputting the numeric information is completed the entire numeric information is displayed on LCD  201  and the sound is output from speaker  216  under control of CPU  211  (S 10 ). If the numeric information is correct (S 11 ) communication device  200  ( FIG. 1 ) initiates the dialing process by using the numeric information (S 12 ). The dialing process continues until communication device  200  is connected to another device (S 13 ). Once CPU  211  detects that the line is connected it automatically deactivates the voice recognition system (S 14 ). CPU  211  checks the status communication device  200  periodically (S 1 ) as described in  FIG. 7  and remains the voice recognition system offline during call (S 2 ). If the connection is severed, i.e., user hangs up, then CPU  211  reactivates the voice recognition system (S 3 ). 
     Voice Recognition—Tag 
       FIG. 8  through  FIG. 12  describes the method of inputting the numeric information in a convenient manner. RAM  206  includes Table # 1  ( FIG. 8 ) and Table # 2  ( FIG. 9 ). In  FIG. 8  audio information # 1  corresponds to tag “Scott.” Namely audio information, such as wave data, which represents the sound of “Scott” (sounds like “S-ko-t”) is registered in Table # 1 , which corresponds to tag “Scott”. In the same manner audio information # 2  corresponds to a tag “Carol”; audio information # 3  corresponds to a tag “Peter”; audio information # 4  corresponds to a tag “Amy”; and audio information # 5  corresponds to a tag “Brian.” In  FIG. 9  tag “Scott” corresponds to numeric information “(916) 411-2526”; tag “Carol” corresponds to numeric information “(418) 675-6566”; tag “Peter” corresponds to numeric information “(220) 890-1527”; tag “Amy” corresponds to numeric information “(615) 125-3411”; and tag “Brian” corresponds to numeric information “(042) 643-2097.”  FIG. 11  illustrates how CPU  211  ( FIG. 1 ) operates by utilizing both Table # 1  and Table # 2 . Once the audio data is processed as described in S 4  of  FIG. 6  CPU  211  scans Table # 1  (S 1 ). If the retrieved audio data matches with one of the audio information registered in Table # 1  (S 2 ) it scans Table # 2  (S 3 ) and retrieves the corresponding numeric information from Table # 2  (S 4 ).  FIG. 10  illustrates another embodiment of the present invention. Here, RAM  206  includes Table #A instead of Table # 1  and Table # 2  described above. In this embodiment audio info # 1  (i.e., wave data which represents the sound of “Scot”) directly corresponds to numeric information “(916) 411-2526.” In the same manner audio info # 2  corresponds to numeric information “(410) 675-6566”; audio info # 3  corresponds to numeric information “(220) 890-1567”; audio info # 4  corresponds to numeric information “(615) 125-3411”; and audio info # 5  corresponds to numeric information “(042)645-2097.”  FIG. 12  illustrates how CPU  211  ( FIG. 1 ) operates by utilizing Table #A. Once the audio data is processed as described in S 4  of  FIG. 6  CPU  211  scans Table #A (S 1 ). If the retrieved audio data matches with one of the audio information registered in Table #A (S 2 ) it retrieves the corresponding numeric information therefrom (S 3 ). As another embodiment RAM  206  may contain only Table # 2  and tag can be retrieved from the voice recognition system explained in  FIG. 3  through  FIG. 7 . Namely once the audio data is processed by CPU  211  as described in S 4  of  FIG. 6  and retrieves the text data therefrom and detects one of the tags registered in Table # 2  (e.g., “Scot”) it retrieves the corresponding numeric information (e.g., “(916) 411-2526”) from the same table. 
     Voice Recognition—Background Noise Filter 
       FIG. 13  through  FIG. 15  describes the method of minimizing the undesired effect of the background noise. ROM  207  includes area  255  and area  256 . Sound audio data which represents background noise is stored in area  255 , and sound audio data which represents the beep, ringing sound and other sounds which are emitted from the communication device  200  are stored in area  256 .  FIG. 14  describes how these data are utilized. When the voice recognition system is activated as described in  FIG. 5  the analog audio data is input from microphone  215  ( FIG. 1 ) (S 1 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) (S 3 ) and compared to the data stored in area  255  and area  256  (S 4 ). Such comparison can be done by either sound processor  205  or CPU  211 . If the digital audio data matches to the data stored in area  255  and/or area  256  the filtering process is initiated and deleted as background noise. Such sequence of process is done before retrieving text and numeric information from the digital audio data.  FIG. 14   a  describes the method of updating area  255 . When the voice recognition system is activated as described in  FIG. 5  the analog audio data is input from microphone  215  ( FIG. 1 ) (S 1 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) (S 3 ) and the background noise is captured (S 4 ). CPU  211  ( FIG. 1 ) scans area  255  and if the captured background noise is not registered in area  255  it updates the sound audio data stored therein.  FIG. 15  describes another embodiment of the present invention. CPU  211  ( FIG. 1 ) routinely checks whether the voice recognition system is activated (S 1 ). If the system is activated (S 2 ) the beep, ringing sound and other sounds which are emitted from the communication device  200  are automatically turned off (S 3 ). 
     Voice Recognition—Automatic Turn-Off 
     The voice recognition system can automatically be turned off to avoid glitch as described in  FIG. 16 . When the voice recognition system is activated (S 1 ) CPU  211  ( FIG. 1 ) automatically sets a timer (S 2 ). The value of timer (i.e., the length of time until the system is deactivated) can be set manually by the user. The timer is incremented periodically (S 3 ) and if the incremented time equals to the predetermined value of time as set in S 2  (S 4 ) the voice recognition system is automatically deactivated (S 5 ). 
     Voice Recognition—E-Mail 
       FIG. 17   a  and  FIG. 17   b  illustrate the method of typing and sending e-mails by utilizing the voice recognition system. Once the voice recognition system is activated (S 1 ) the analog audio data is input from microphone  215  ( FIG. 1 ) (S 2 ). The analog audio data is converted into digital data by A/D  213  ( FIG. 1 ) (S 3 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) to retrieve the text and numeric information therefrom (S 4 ). Then the text and numeric information are retrieved (S 5 ) and displayed on LCD  201  ( FIG. 1 ) (S 6 ). If the retrieved information is not correct (S 7 ) the user can input the correct text and/or numeric information manually by using the input device  210  ( FIG. 1 ) (S 8 ). If inputting the text and numeric information is completed (S 9 ) and CPU  211  detects input signal from input device  210  to send the e-mail (S 10 ) the dialing process is initiated (S 11 ). The dialing process is repeated until communication device  200  is connected to its host (S 12 ) and the e-mail is sent to the designated address (S 13 ). 
     Voice Recognition—Speech-to-Text 
       FIG. 18  illustrates the speech-to-text function of communication device  200 . Once communication device  200  receives a transmitted data from another device via antenna  218  ( FIG. 1 ) (S 1 ) signal processor  208  ( FIG. 1 ) processes the data (e.g., such as decompression) (S 2 ) and the transmitted data is converted into audio data (S 3 ). Such conversion can be done by either CPU  211  ( FIG. 1 ) or signal processor  208 . The audio data is transferred to sound processor  205  ( FIG. 1 ) via data bus  203  and text and numeric information are retrieved therefrom (S 4 ). CPU  211  designates the predetermined font and color to the text and numeric information (S 5 ) and also designates a tag to such information (S 6 ). After these tasks are completed the tag and the text and numeric information are stored in RAM  206  and displayed on LCD  201  (S 7 ).  FIG. 19  illustrates how the text and numeric information as well as the tag are displayed. On LCD  201  the text and numeric information  702  (“XXXXXXXXX”) are displayed with the predetermined font and color as well as with the tag  701  (“John”). 
     Positioning System 
       FIG. 20   a  illustrates the simplified block diagram to detect the position of communication device  200 . In  FIG. 20   a  relay R 1  is connected to cable C 1 , relay R 2  is connected to cable C 2 , relay R 3  is connected to cable C 3 , and relay R 4  is connected to cable C 4 . Cables C 1 , C 2 , C 3 , and C 4  are connected to transmitter T, which is connected to host H by cable C 5 . The relays (R  1  . . . R  20 ) are located throughout the predetermined area in the pattern illustrated in  FIG. 20   b . The system illustrated in  FIG. 20   a  and  FIG. 20   b  is designed to pin-point the position of communication device  200  by using the method so-called “global positioning system” or “GPS.” 
       FIG. 21  through  FIG. 26  illustrate how the positioning is performed. Assuming that device A, communication device  200 , seeks to detect the position of device B, another communication device  200 , which is located somewhere in the matrix of relays illustrated in  FIG. 20   b . First of all the device ID of device B is entered by using input device  210  ( FIG. 1 ) of device A (S 1 ). The device ID may be its corresponding phone number. A request data including the device ID is sent to host H from device A (S 2 ). 
     As illustrated in  FIG. 22  host H periodically receives data from Device A (S 1 ). If the received data is the request data (S 2 ) host H first of all searches its communication log which records the location of device B which it last communicated with host H (S 3 ). Then host H sends search signal from relays described in  FIG. 20   b  which are located within 100 meter radius from the location registered in the communication log. If there is no response from Device B (S 5 ) host H sends search signal from all relays (from R 1  to R 20  in  FIG. 20   b ) (S 6 ). 
     As illustrated in  FIG. 23  device B periodically receives data from host H (S 1 ). If the data received is the search signal (S 2 ) device B sends response signal to host H (S 3 ). 
     As illustrated in  FIG. 24  host H periodically receives data from device B (S 1 ). If the data received is the response signal (S 2 ) host H locates the position of device B by using the method described in  FIG. 20   a  and  FIG. 20   b  (S 3 ), and sends the location data and the relevant map data of the area where device B is located to device A (S 4 ). 
     As illustrated in  FIG. 25  device A periodically receives data from host H (S 1 ). If the data received is the location data and the relevant map data mentioned above device A displays the map based on the relevant map data and indicates the location thereon based on the location data (S 3 ). 
     Device A can continuously track down the location of device B as illustrated in  FIG. 26 . First, device A sends a request data to host H (S 1 ). As soon as host H receives the request data (S 2 ) it sends a search signal in the manner illustrated in  FIG. 22  (S 3 ). As soon as device B receives the search signal (S 4 ) it sends a response signal to host H (S 5 ). Based on the response signal host H locates device B with the method described in  FIG. 20   a  and  FIG. 20   b  (S 6 ). Then host H sends to device A a renewed location data and a relevant map data of the area where device B is located (S 7 ). As soon as these data are received (S 8 ) device A displays the map based on the relevant map data and indicates the updated location based on the renewed location data (S 9 ). If device B is still within the specified area device A may use the original relevant map data. As another embodiment of the present invention S 1  through S 4  may be omitted and make device B send a response signal continuously to host H until host H sends a command signal to device B to cease sending the response signal. 
     Positioning System—Automatic Silent Mode 
       FIG. 27   a  through  FIG. 32   g  illustrate the automatic silent mode of communication device  200 . 
     In  FIG. 27   a  relay R 1  is connected to cable C 1 , relay R 2  is connected to cable C 2 , relay R 3  is connected to cable C 3 , and relay R 4  is connected to cable C 4 . Cables C 1 , C 2 , C 3 , and C 4  are connected to transmitter T, which is connected to host H by cable C 5 . The relays (R  1  . . . R  20 ) are located throughout the predetermined area in the pattern illustrated in  FIG. 27   b . The system illustrated in  FIG. 27   a  and  FIG. 27   b  is designed to pin-point the position of communication device  200  by using the method so-called “global positioning system” or “GPS.” 
     As illustrated in  FIG. 28  the user of communication device  200  may set the silent mode by input device  210  ( FIG. 1 ). When communication device  200  is in the silent mode (a) the ringing sound is turned off, (b) vibrator  217  ( FIG. 1 ) activates when communication device  200  receives call, and/or (c) communication device  200  sends a automatic response to the caller device when a call is received. The user may, with his discretion, select any of these predetermined function of the automatic silent mode. 
       FIG. 29  illustrates how the automatic silent mode is activated. Communication device  200  checks its present location with the method so-called “global positioning system” or “GPS” by using the system illustrated in  FIG. 27   a  and  FIG. 27   b  (S 1 ). Communication device  200  then compares the present location and the previous location (S 2 ). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of communication device  200  exceeds the predetermined value (S 3 ) the silent mode is activated and (a) the ringing sound is automatically turned off, (b) vibrator  217  ( FIG. 1 ) activates, and/or (c) communication device  200  sends an automatic response to the caller device according to the user&#39;s setting. Here, the silent mode is automatically activated because the user of communication device  200  is presumed to be on an automobile and is not in a situation to freely answer the phone, or the user is presumed to be riding a train and does not want to disturb other passengers. 
     As another embodiment of the present invention the automatic silent mode may be administered by host H ( FIG. 27   a ). As illustrated in  FIG. 30  the silent mode is set in the manner described in  FIG. 28  (S 1 ) and communication device  200  sends to host H a request signal. When host H detects a call to communication device  200  after receiving the request signal it checks the current location of communication device  200  (S 1 ) and compares it with the previous location (S 2 ). If the difference of the two values is more than the specified amount X, i.e., when the moving velocity of communication device  200  exceeds the predetermined value (S 3 ) host H sends a notice signal to communication device  200  (S 4 ). As illustrated in  FIG. 32  communication device  200  receives data periodically from host H (S 1 ). If the received data is a notice signal (S 2 ) communication device  200  activates the silent mode (S 3 ) and (a) the ringing sound is automatically turned off, (b) vibrator  217  ( FIG. 1 ) activates, and/or (c) communication device  200  sends an automatic response to the caller device according to the user&#39;s setting. The automatic response may be sent from host H instead. 
     As another embodiment of the present invention a train route data may be used. As illustrated in  FIG. 32   a  the train route data is stored in area  263  of RAM  206 . The train route data contains three-dimensional train route map including the location data of the route.  FIG. 32   b  illustrates how the train route data is utilized. CPU  211  ( FIG. 1 ) checks the present location of communication device  200  by the method described in  FIG. 27   a  and  FIG. 27   b  (S 1 ). Then CPU  211  compares with the train route data stored in area  263  of RAM  206  (S 2 ). If the present location of communication  200  matches the train route data (i.e., if communication device is located on the train route) (S 3 ) the silent mode is activated in the manner described above. The silent mode is activated because the user of communication device  200  is presumed to be currently on the train and may not want to disturb the other passengers on the same train. As another embodiment of the present invention such function can be delegated to host H ( FIG. 27   a ) as described in  FIG. 32   c . Namely, host H checks the present location of communication device  200  by the method described in  FIG. 27   a  and  FIG. 27   b  (S 1 ). Then host H compares the present location with the train route data stored in its own storage (not shown) (S 2 ). If the present location of communication  200  matches the train route data (i.e., if communication device is located on the train route) (S 3 ) host H sends a notice signal to communication device  200  thereby activating the silent mode in the manner described above. 
     Another embodiment is illustrated in  FIG. 32   f  and  FIG. 32   g . As illustrated in  FIG. 32   f  relays R  101 , R  102 , R  103 , R  104 , R  105 , R  106 , which perform the same function to the relays described in  FIG. 27   a  and  FIG. 27   b , are installed in train Tr. The signals from these relays are sent to host H illustrated in  FIG. 27   a . Relays R  101  through R  106  emit inside-the-train signals which are emitted only inside train Tr.  FIG. 32   g  illustrates how communication device  200  operates inside train Tr. Communication device  200  checks the signal received in train Tr (S 1 ). If communication device  200  determines that the signal received is an inside-the-train signal (S 2 ) it activates the silent mode in the manner described above. 
     Positioning System—Auto Response 
       FIG. 32   d  and  FIG. 32   e  illustrates the method to send an automatic response to a caller device when the silent mode is activated. Assume that the caller device, a communication device  200 , intends to call a callee device, another communication device  200  via host H. As illustrated in  FIG. 32   d  the caller device dials the callee device and the dialing signal is sent to host H (S 1 ). Host H checks whether the callee device is in the silent mode (S 2 ). If host H detects that the callee device is in the silent mode it sends a predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is received by the caller device (S 3 ). If the user of the caller device still desires to request for connection and certain code is input from input device  210  ( FIG. 1 ) (S 4 ) a request signal for connection is sent and received by host H (S 5 ), and the line is connected between the caller device and the callee device via host H (S 6 ). As another embodiment of the present invention the task of host H which is described in  FIG. 32   d  may be delegated to the callee device as illustrated in  FIG. 32   e . The caller device dials the callee device and the dialing signal is sent to the callee device via host H (S 1 ). The callee device checks whether it is in the silent mode (S 2 ). If the callee device detects that it is in the silent mode it sends an predetermined auto response which indicates that the callee is probably on a train and may currently not be available, which is sent to the caller device via host H (S 3 ). If the user of the caller device still desires to request for connection and certain code is input from input device  210  ( FIG. 1 ) (S 4 ) a request signal for connection is sent to the callee device via host H (S 5 ), and the line is connected between the caller device and the callee device via host H (S 6 ). 
     Auto Backup 
       FIG. 32  through  FIG. 37  illustrate the automatic backup system of communication device  200 . As illustrated in  FIG. 32  RAM  206  ( FIG. 1 ) includes areas to store the data essential to the user of communication device  200 , such as area  278  for a phone list, area  279  for an address book, area  280  for email data, area  281  for software A, area  282  for software B, area  283  for software C, area  284  for data D, area  285  for data E. RAM  206  also includes area  264 , i.e., the selected data info storage area, which will be explained in details hereinafter. 
     As described in  FIG. 34  the user selects data by using input device  210  ( FIG. 1 ) which he/she intends to be automatically backed up (S 1 ). The selected data are written in area  264 , the selected data info storage area (S 2 ). 
     The overall operation of this function is illustrated in  FIG. 35   a  and  FIG. 35   b . First of all, a timer (not shown) is set by a specific input signal produced by input device  210 ″( FIG. 1 ) (S 1 ). The timer is incremented periodically (S 2 ) and when the incremented value equals the predetermined value (S 3 ) communication device  200  initiates the dialing process (S 4 ). The dialing process continues until communication device  200  is connected to host  400  explained in  FIG. 37  (S 5 ). Once the line is connected CPU  211  reads the information stored in area  264  (S 6 ) and based on such information it initiates to transfer the selected data from RAM  206  to host  400  (S 7 ). The transfer continues until all of the selected data are transferred to host  400  (S 8 ) and the line is disconnected thereafter (S 9 ). This backup sequence can be initiated automatically and periodically by using a timer or manually. As another embodiment of the present invention, instead of selecting the data that are to be backed up, all data in RAM  206  ( FIG. 1 ) can be transferred to host  400 . 
       FIG. 36  illustrates the basic structure of the data transferred to host  400 . Transferred data  601  includes header  602 , device ID  603 , selected data  604  and footer  605 . Device ID  603  is the identification number of communication device  200  preferably its phone number, and selected data  604  is the pack of data which are transferred from RAM  206  to host  400  based on information stored in area  264 . 
       FIG. 37  illustrates the basic structure of host  400 . Host  400  includes backup data storage area  401  which is used to backup all of the backup data transferred from all communication devices. Host  400  stores the transferred data  601  to the designated area based on the device ID included in transferred data  601 . For example, transferred data  601  transferred from device A is stored in area  412  as backup data A. In the same manner transferred data  601  transferred from device B is stored in area  413  as backup data B; transferred data  601  transferred from device C is stored in area  414  as backup data C; transferred data  601  transferred from device D is stored in area  415  as backup data D; transferred data  601  transferred from device E is stored in area  416  as backup data E; and transferred data  601  transferred from device F is stored in area  417  as backup data F. 
     Signal Amplifier 
       FIG. 38  illustrates a signal amplifier utilized for automobiles and other transportation carriers, such as trains, airplanes, space shuttles, and motor cycles. As described in  FIG. 38  automobile  500  includes interface  503 , an interface detachably connectable to communication device  200 , which is connected to amplifier  502  via cable  505 : Amplifier  502  is connected to antenna  501  via cable  504  and connector  507  as described in this drawing. The signal produced by communication device  200  is transferred to interface  503 . Then the signal is transferred to amplifier via cable  505  where the signal is amplified. The amplified signal is transferred to antenna  501  via cable  504  and connector  507 , which transmits the amplified signal to host H (not shown). The receiving signal is received by antenna  501  and transferred to amplifier  502  via connector  507  and cable  504 , and then is transferred to interface  503  via cable  505 , which transfers the amplified signal to communication device  200 . 
     Audio/Video Data Capturing System 
       FIG. 39  through  FIG. 44  illustrate the audio/video capturing system of communication device  200 . Assuming that device A, a communication device  200 , captures audio/video data and transfers such data to device B, another communication device  200 , via a host (not shown). Primarily video data is input from CCD unit  214  ( FIG. 1 ) and audio data is input from microphone  215  of ( FIG. 1 ) of device A. As illustrated in  FIG. 39  RAM  206  includes area  267  which stores audio data, area  268  which stores video data, and area  265  which is a work area utilized for the process explained hereinafter. 
     As described in  FIG. 40  the video data input from CCD unit  214  (S 1   a ) is converted from analog data to digital data (S 2   a ) and is processed by CCD unit  214  (S 3   a ). Area  265  is used as work area for such process. The processed video data is stored in area  267  of RAM  206  (S 4   a ) and displayed on LCD  201  ( FIG. 1 ). As described in the same drawing the audio data input from microphone  215  (S 1   b ) is converted from analog data to digital data by A/D  213  ( FIG. 1 ) (S 2   b ) and is processed by sound processor  205  ( FIG. 1 ) (S 3   b ). Area  265  is used as work area for such process. The processed audio data is stored in area  268  of RAM  206  (S 4   b ) and is transferred to sound processor  205  and is output from speaker  216  ( FIG. 1 ) via D/A  204  ( FIG. 1 ) (S 5   b ). The sequences of S 1   a  through S 5   a  and S 1   b  through S 5   b  are continued until a specific signal indicating to stop such sequence is input from input device  210  ( FIG. 1 ) (S 6 ). 
     As described in  FIG. 41  CPU  211  ( FIG. 1 ) of device A initiates a dialing process (S 1 ) until the line is connected to a host (not shown) (S 2 ). As soon as the line is connected CPU  211  reads the audio/video data stored in area  267  and area  268  (S 3 ) and transfer them to signal processor  208  where the data are converted into a transferring data (S 4 ). The transferring data is transferred from antenna  218  in a wireless fashion (S 5 ). The sequence of S 1  through S 5  is continued until a specific signal indicating to stop such sequence is input from input device  210  ( FIG. 1 ) (S 6 ). The line is disconnected thereafter (S 7 ). 
       FIG. 42  illustrates the basic structure of the transferred data which is transferred from device A as described in S 4  and S 5  of  FIG. 41 . Transferred data  610  is primarily composed of header  611 , video data  612 , audio data  613 , relevant data  614 , and footer  615 . Video data  612  corresponds to the video data stored in area  267  of RAM  206 , and audio data  613  corresponds to the audio data stored in area  268  of RAM  206 . Relevant data  614  includes various types of data, such as the identification number of device A (i.e., transferor device) and device B (transferee device), a location data which represents the location of device A, etc. 
       FIG. 43  illustrates the data contained in RAM  206  ( FIG. 1 ) of device B. As illustrated in  FIG. 39  RAM  206  includes area  269  which stores audio data, area  270  which stores video data, and area  266  which is a work area utilized for the process explained hereinafter. 
     As described in  FIG. 44   a  and  FIG. 44   b  CPU  211  ( FIG. 1 ) of device B initiates a dialing process (S 1 ) until device B is connected to a host (not shown) (S 2 ). Transferred data  610  is received by antenna  218  ( FIG. 1 ) of device B (S 3 ) and is converted by signal processor  208  into a readable data which is readable by CPU  211  (S 4 ). Video data and audio data are retrieved from transferred data  610  and stored into area  269  and area  270  of RAM  206  respectively (S 5 ). The video data stored in area  269  is processed by video processor  202  ( FIG. 1 ) (S 6   a ). The processed video data is converted into an analog data (S 7   a ) and displayed on LCD  201  ( FIG. 1 ) (S 8   a ). S 7   a  may not be necessary depending on the type of LCD  201  used. The audio data stored in area  270  is processed by sound processor  205  ( FIG. 1 ) (S 6   b ). The processed audio data is converted into analog data by D/A  204  ( FIG. 1 ) (S 7   b ) and output from speaker  216  ( FIG. 1 ) (S 8   b ). The sequences of S 6   a  through S 8   a  and S 6   b  through S 8   b  are continued until a specific signal indicating to stop such sequence is input from input device  210  ( FIG. 1 ) (S 9 ). 
     Digital Mirror 
       FIG. 44   c  through  FIG. 44   e  illustrates the method of using communication device  200  as a mirror. In this embodiment communication device  200  includes rotator  291  as described in  FIG. 44   c . Rotator  291  is fixed to the side of communication device  200  and rotates CCD unit  214  ( FIG. 1 ) and thereby CCD unit  214  is enabled to face multi-direction. CPU  211  ( FIG. 1 ) reads the video data stored in area  267  ( FIG. 39 ) from left to right as described in  FIG. 44   d  when CCD unit  214  is facing the opposite direction from LCD  201 . However, when CCD unit  214  is facing the same direction with LCD  201 , CPU  211  reads the video data stored in area  267  from right to left as described in  FIG. 44   e  thereby producing a “mirror image” on LCD  201 . 
     As another embodiment of the present invention more than one CCD units which face multi-direction may be utilized instead of enabling one CCD unit to rotate in the manner described above. 
     Caller ID 
       FIG. 45  through  FIG. 47  illustrate the caller ID system of communication device  200 . 
     As illustrated in  FIG. 45  RAM  206  includes Table C. As shown in the drawing each phone number corresponds to a specific color and sound. For example phone # 1  corresponds to color A and sound E; phone # 2  corresponds to color B and sound F; phone # 3  corresponds to color C and sound G; and phone # 4  corresponds to color D and sound H. 
     As illustrated in  FIG. 46  the user of communication device  200  selects or inputs a phone number (S 1 ) and selects a specific color (S 2 ) and a specific sound (S 3 ) designated for that phone number. Such sequence can be repeated until there is a specific input from input device  210  ordering to do otherwise (S 4 ). 
     As illustrated in  FIG. 47  CPU  211  ( FIG. 1 ) periodically checks whether it has received a call from other communication devices (S 1 ). If it receives a call (S 2 ) CPU  211  scans Table C ( FIG. 45 ) to see whether the phone number of the caller device is registered in the table (S 3 ). If there is a match (S 4 ) the designated color is output from indicator  212  ( FIG. 1 ) and the designated sound is output from speaker  216  ( FIG. 1 ) (S 5 ). For example if the incoming call is from phone # 1  color A is output from indicator  212  and sound E is output from speaker  216 . 
     Stock Purchase 
       FIG. 48  through  FIG. 52  illustrate the method of purchasing stocks by utilizing communication device  200 . 
       FIG. 48  illustrates the data stored in ROM  207  ( FIG. 1 ) necessary to set the notice mode. Area  251  stores the program regarding the vibration mode; area  252  stores the program regarding sound which is emitted from speaker  216  ( FIG. 1 ) and several types of sound data, such as sound data I, sound data J, and sound data K; area  253  stores the program regarding the color emitted from indicator  212  ( FIG. 1 ) and several types of color data, such as color data L, color data, M, and color data N. 
     As illustrated in  FIG. 49  the notice mode is activated in the manner in compliance with the settings stored in setting data area  271  of RAM  206 . In the example illustrated in  FIG. 49  when the notice mode is activated vibrator  217  ( FIG. 1 ) is turned on in compliance with the data stored in area  251   a , speaker  216  ( FIG. 1 ) is turned on and sound data J is emitted therefrom in compliance with the data stored in area  252   a , and indicator  212  ( FIG. 1 ) is turned on and color M is emitted therefrom in compliance with the data stored in area  253   a . Area  292  stores the stock purchase data, i.e., the name of the brand, the amount of limited price, the name of the stock market (such as NASDAQ and/or NYSE) and other relevant information regarding the stock purchase. 
     As illustrated in  FIG. 50  the user of communication device  200  inputs the stock purchase data from input device  210  ( FIG. 1 ), which is stored in area  292  of RAM  206  (S 1 ). By way of inputting specific data from input device  210  the property of notice mode (i.e., vibration ON/OFF, sound ON/OFF and the type of sound, indicator ON/OFF and the type of color) is set and the relevant data are stored in area  271  (i.e., areas  251   a ,  252   a ,  253   a ) of RAM  206  by the programs stored in areas  251 ,  252 ,  253  of ROM  207  (S 2 ). Communication device  200  initiates a dialing process (S 3 ) until it is connected to host H (described hereafter) (S 4 ) and sends the stock purchase data thereto. 
       FIG. 51  illustrates the operation of host H. As soon as host H receives the stock purchase data from communication device  200  (S 1 ) it initiates monitoring the stock markets which is specified in the stock purchase data (S 2 ). If host H detects that the price of the certain brand specified in the stock purchase data meets the limited price specified in the stock purchase data (S 3 ) it initiates a dialing process (S 4 ) until it is connected to communication device  200  (S 5 ) and sends a notice data thereto (S 6 ). As illustrated in  FIG. 52  communication device  200  periodically monitors the data received from host H (S 1 ). If the data received is a notice data (S 2 ) the notice mode is activated in the manner in compliance with the settings stored in setting data area  271  of RAM  206  (S 3 ). In the example illustrated in  FIG. 49  vibrator  217  ( FIG. 1 ) is turned on, sound data J is emitted from speaker  216  ( FIG. 1 ), and indicator  212  ( FIG. 1 ) emits color M. 
     Timer Email 
       FIG. 53   a  and  FIG. 53   b  illustrate the method of sending emails from communication device  200  by utilizing a timer. Address data, i.e., email address is input by input device  210  or by voice recognition system explained in  FIG. 3 ,  FIG. 4 ,  FIG. 5 ,  FIG. 13 ,  FIG. 14 ,  FIG. 14   a ,  FIG. 15 ,  FIG. 16  and/or  FIG. 17  (S 1 ) and the text data, the text of the email message is input by the same manner (S 2 ). The address data and the text data are automatically saved in RAM  206  ( FIG. 1 ) (S 3 ). The sequence of S 1  through S 3  is repeated (i.e., writing more than one email) until a specified input signal is input from input device  210  or by utilizing the voice recognition system explained above ( FIG. 1 ). Once inputting both the address data and the text data (which also includes numeric data, images and programs) are completed a timer (not shown) is set by input device  210  or by utilizing the voice recognition system (S 5 ), and the timer is incremented periodically (S 6 ) until the timer value equals the predetermined value specified in S 5  (S 7 ). A dialing process is continued (S 8 ) until the line is connected (S 9 ) and the text data are sent thereafter to email addresses specified in S 1  (S 10 ). All of the emails are sent (S 11 ) and the line is disconnected thereafter (S 12 ). 
     As another embodiment of the present invention a specific time may be input by input device  210  and send the text data on the specific time (i.e., a broad meaning of “timer”). 
     Call Blocking 
       FIG. 54  through  FIG. 56  illustrates the method of so-called “call blocking.” 
     As illustrated in  FIG. 54  RAM  206  ( FIG. 1 ) includes area  273  and area  274 . Area  273  stores phone numbers that should be blocked. In the example illustrated in  FIG. 54  phone # 1 , phone # 2 , and phone # 3  are blocked. Area  274  stores a message data stating that the phone can not be connected. 
       FIG. 55  illustrates the operation of communication device  200 . When communication device  200  receives a call (S 1 ), CPU  211  ( FIG. 1 ) scans area  273  of RAM  206  (S 2 ). If the phone number of the incoming call matches one of the phone numbers stored in area  273  of RAM  206  (S 3 ) CPU  211  sends the message data stored in area  274  of RAM  206  to the caller device (S 4 ) and disconnects the line (S 5 ). 
       FIG. 56  illustrates the method of updating area  273  of RAM  206 . Assuming that the phone number of the incoming call does not match any of the phone numbers stored in area  273  of RAM  206  (see S 3  of  FIG. 55 ). In that case communication device  200  is connected to the caller device. However, the user of communication device  200  may decide to have such number “blocked” after all. In that case the user dials “999” while the line is connected. Technically CPU  211  ( FIG. 1 ) periodically checks the signals input from input device  210  ( FIG. 1 ) (S 1 ). If the input signal represents “9991” from input device  210  (S 2 ) CPU  211  adds the phone number of the pending call to area  273  (S 3 ) and sends the message data stored in area  274  of RAM  206  to the caller device (S 4 ). The line is disconnected thereafter (S 5 ). 
       FIG. 57  through  FIG. 59  illustrates another embodiment of the present invention. 
     As illustrated in  FIG. 57  host  400  includes area  403  and area  404 . Area  403  stores phone numbers of communication device  200  that should be blocked. In the example illustrated in  FIG. 57  phone # 1 , phone # 2 , and phone # 3  are blocked for device A; phone # 4 , phone # 5 , and phone # 6  are blocked for device B; and phone # 7 , phone # 8 , and phone # 9  are blocked for device C. Area  404  stores a message data stating that the phone can not be connected. 
       FIG. 58  illustrates the operation of host  400 . Assuming that the caller device is attempting to connect to device B illustrated in  FIG. 57 . Host  400  periodically checks the signals from all communication device  200  (S 1 ). If host  400  detects a call for device B (S 2 ) it scans area  403  and checks whether the phone number of the incoming call matches one of the phone numbers stored therein (S 4 ). If the phone number of the incoming call does not match any of the phone numbers stored in area  403  the line is connected to device B (S 5   b ). On the other hand, if the phone number of the incoming call matches one of the phone numbers stored in area  403  the line is “blocked,” i.e., not connected to device B (S 5   a ) and host  400  sends the massage data stored in area  404  to the caller device (S 6 ). 
       FIG. 59  illustrates the method of updating area  403  of host  400 . Assuming that the phone number of the incoming call does not match any of the phone numbers stored in area  403  (see S 4  of  FIG. 58 ). In that case host  400  allows the connection between the caller device and communication device  200 . However, the user of communication device  200  may decide to have such number “blocked” after all. In that case the user simply dials “999” while the line is connected. Technically host  400  ( FIG. 57 ) periodically checks the signals input from input device  210  ( FIG. 1 ) (S 1 ). If the input signal represents “999” from input device  210  ( FIG. 1 ) (S 2 ) host  400  adds the phone number of the pending call to area  403  (S 3 ) and sends the message data stored in area  404  to the caller device (S 4 ). The line is disconnected, thereafter (S 5 ). As another embodiment of the method illustrated in  FIG. 59  host  400  may delegate some of its tasks to communication device  200  (this embodiment is not shown in drawings). Namely communication device  200  periodically checks the signals input from input device  210  ( FIG. 1 ). If the input signal represents “999” from input device  210  communication device  200  sends to host a block request signal as well as with the phone number of the pending call. Host  400 , upon receiving the block request signal from communication device  200 , adds the phone number of the pending call to area  403  and sends the message data stored in area  404  to the caller device. The line is disconnected thereafter. 
     Online Payment 
       FIG. 60  through  FIG. 64  illustrates the method of online payment by utilizing communication device  200 . 
     As illustrated in  FIG. 60  host  400  includes account data storage area  405 . All of the account data of the users of communication device  200  who have signed up for the online payment service are stored in area  405 . In the example described in  FIG. 60  account A stores the relevant account data of the user using device A; account B stores the relevant account data of the user using device B; account C stores the relevant account data of the user using device C; and account D stores the relevant account data of the user using device D. Here, device A, B, C, and D are communication device  200 . 
       FIG. 61   a  and  FIG. 61   b  illustrate the operation of the payer device. Assuming that device A is the payer device and device B is the payee device. Account A explained in  FIG. 60  stores the account data of the user of device A, and account B explained in the same drawing stores the account data of the user of device B. As illustrated in  FIG. 61   a  LCD  201  of device A displays the balance of account A by receiving the relevant data from host  400  ( FIG. 60 ) (S 1 ). From the signal input from input device  210  ( FIG. 1 ) the payer&#39;s account and the payee&#39;s account are selected (in the present example account A as the payer&#39;s account and account B as the payee&#39;s account), the amount of payment and the device ID (in the present example device A as the payer&#39;s device and device B as the payee&#39;s device) (S 2 ). If the data input from input device  210  is correct (S 3 ) CPU  211  ( FIG. 1 ) of device A prompts for other payments. If there are other payments to make the sequence of S 1  through S 3  is repeated until all of the payments are made (S 4 ). The dialing process is initiated and repeated thereafter (S 5 ) until the line is connected to host  400  (S 6 ). Once the line is connected device A sends the payment data to host  400  ( FIG. 60 ) (S 7 ). The line is disconnected when all of the payment data are sent to host  400  (S 8  and S 9 ). 
       FIG. 62  illustrates the payment data described in S 7  of  FIG. 61   b . Payment data  620  is consisted of header  621 , payer&#39;s account information  622 , payee&#39;s account information  623 , amount data  624 , device ID data  625 , and footer  615 . Payer&#39;s account information  622  represents the information regarding the payer&#39;s account data stored in host  400  which is, in the present example, account A. Payee&#39;s account information  623  represents the information regarding the payee&#39;s account data stored in host  400  which is, in the present example, account B. Amount data  624  represents the amount of monetary value either in the U.S. dollars or in other currencies which is to be transferred from the payer&#39;s account to the payee&#39;s account. The device ID data represents the data of the payer&#39;s device and the payee&#39;s device, i.e., in the present example, device A and device B. 
       FIG. 63  illustrates the basic structure of the payment data described in S 7  of  FIG. 61   b  when multiple payments are made, i.e., when more than one payment is made in S 4  of  FIG. 61   a . Assuming that three payments are made in S 4  of  FIG. 61   a . In that case payment data  630  is consisted of header  631 , footer  635 , and three data sets, i.e., data set  632 , data set  633 , data set  634 . Each data set represents the data components described in  FIG. 62  excluding header  621  and footer  615 . 
       FIG. 64  illustrates the operation of host  400  ( FIG. 60 ). After receiving payment data from device A described in  FIG. 62  and  FIG. 63  host  400  retrieves therefrom the payer&#39;s account information (in the present example account A), the payee&#39;s account information (in the present example account B), the amount data which represents the monetary value, the device IDs of both the payer&#39;s device and the payee&#39;s device (in the present example device A and device B) (S 1 ). Host  400  based on such data subtracts the monetary value represented by the amount data from the payer&#39;s account (in the present example account A) (S 2 ), and adds the same amount to the payee&#39;s account (in the present example account B) (S 3 ). If there are other payments to make, i.e., if host  400  received a payment data which has a structure of the one described in  FIG. 63  the sequence of S 2  and S 3  is repeated as many times as the amount of the data sets are included in such payment data. 
     Navigation System 
       FIG. 65  through  FIG. 74  illustrate the navigation system of communication device  200 . 
     As illustrated in  FIG. 65  RAM  206  ( FIG. 1 ) includes area  275 , area  276 , area  277 , and area  295 . Area  275  stores a plurality of map data, two-dimensional (2D) image data, which are designed to be displayed on LCD  201  ( FIG. 1 ). Area  276  stores a plurality of object data, three-dimensional (3D) image data, which are also designed to be displayed on LCD  201 . The object data are primarily displayed by a method so-called “texture mapping” which is explained in details hereinafter. Here, the object data include the three-dimensional data of various types of objects that are displayed on LCD  201 , such as bridges, houses, hotels, motels, inns, gas stations, restaurants, streets, traffic lights, street signs, trees, etc. Area  277  stores a plurality of location data, i.e., data representing the locations of the objects stored in area  276 . Area  277  also stores a plurality of data representing the street address of each object stored in area  276 . In addition area  277  stores the current position data of communication device  200  and the destination data which are explained in details hereafter. The map data stored in area  275  and the location data stored in area  277  are linked each other. Area  295  stores a plurality of attribution data attributing to the map data stored in area  275  and location data stored in area  277 , such as road blocks, traffic accidents, and road constructions, and traffic jams. The attribution data stored in area  295  is updated periodically by receiving an updated data from a host (not shown). 
     As illustrated in  FIG. 66  video processor  202  ( FIG. 1 ) includes texture mapping processor  290 . Texture mapping processor  290  produces polygons in a three-dimensional space and “pastes” textures to each polygons. 
     As illustrated in  FIG. 67  the voice recognition system is activated when the CPU  211  ( FIG. 1 ) detects a specific signal input from input device  210  ( FIG. 1 ) (S 1 ). After the voice recognition system is activated the input current position mode starts and the current position of communication device  200  is input by voice recognition system explained in  FIG. 3 ,  FIG. 4 ,  FIG. 5 ,  FIG. 13 ,  FIG. 14 ,  FIG. 14   a ,  FIG. 15 ,  FIG. 16  and/or  FIG. 17  (S 2 ). The current position can also be input from input device  210 . As another embodiment of the present invention the current position can automatically be detected by the method so-called “global positioning system” or “GPS” as illustrated in  FIG. 20   a  through  FIG. 26  and input the current data therefrom. After the process of inputting the current data is completed the input destination mode starts and the destination is input by the voice recognition system explained above or by the input device  210  (S 3 ), and the voice recognition system is deactivated after the process of inputting the destination data is completed by using such system (S 4 ). 
       FIG. 68  illustrates the sequence of the input current position mode described in S 2  of  FIG. 67 . When analog audio data is input from microphone  215  ( FIG. 1 ) (S 1 ) such data is converted into digital audio data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) to retrieve text and numeric data therefrom (S 3 ). The retrieved data is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The data can be corrected by repeating the sequence of S 1  through S 4  until the correct data is displayed (S 5 ). If the correct data is displayed such data is registered as current position data (S 6 ). As stated above the current position data can input manually by input device  210  ( FIG. 1 ) and/or by automatically inputting such data by the method so-called “global positioning system” or “GPS” as described above. 
       FIG. 69  illustrates the sequence of the input destination mode described in S 3  of  FIG. 67 . When analog audio data is input from microphone  215  ( FIG. 1 ) (S 1 ) such data is converted into digital audio data by A/D  213  ( FIG. 1 ) (S 2 ). The digital audio data is processed by sound processor  205  ( FIG. 1 ) to retrieve text and numeric data therefrom (S 3 ). The retrieved data is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The data can be corrected by repeating the sequence of S 1  through S 4  until the correct data is displayed (S 5 ). If the correct data is displayed such data is registered as destination data (S 6 ). 
       FIG. 70  illustrates the sequence of displaying the shortest route from the current position to the destination. CPU  211  ( FIG. 1 ) retrieves both the current position data and the destination data which are input by the method described in  FIG. 67  through  FIG. 69  from area  277  of RAM  206  ( FIG. 1 ). By utilizing the location data of streets, bridges, traffic lights and other relevant data CPU  211  calculates the shortest route to the destination (S 1 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from area  275  of RAM  206  (S 2 ). As another embodiment of the present invention by way of utilizing the location data stored in area  277  CPU  211  may produce a three-dimensional map by composing the three dimensional objects (by method so-called “texture mapping” as described above) which are stored in area  276  of RAM  206 . The two-dimensional map and/or the three dimensional map are displayed on LCD  201  ( FIG. 1 ) (S 3 ). As another embodiment of the present invention the attribution data stored in area  295  of RAM  206  may be utilized. Namely if any road block, traffic accident, road construction, and/or traffic jam is included in the shortest route calculated by the method mentioned above, CPU  211  calculates the second shortest route to the destination. If the second shortest route still includes road block, traffic accident, road construction, and/or traffic jam CPU  211  calculates the third shortest route to the destination. CPU  211  calculates repeatedly until the calculated route does not include any road block, traffic accident, road construction, and/or traffic jam. The shortest route to the destination is highlighted by a significant color (such as red) to enable the user of communication device  200  to easily recognize such route on LCD  201 . 
     As another embodiment of the present invention an image which is similar to the one which is observed by the user in the real world may be displayed on LCD  201  ( FIG. 1 ) by using the three-dimensional object data. In order to produce such image CPU  211  ( FIG. 1 ) identifies the present location and retrieves the corresponding location data from area  277  of RAM  206  ( FIG. 65 ). Then CPU  211  retrieves a plurality of object data which correspond to such location data from area  276  or RAM  206  ( FIG. 65 ) and displays a plurality of objects on LCD  201  based on such object data in a manner the user of communication device  200  may observe from the current location. 
       FIG. 71  illustrates the sequence of updating the shortest route to the destination while communication device  200  is moving. By way of periodically and automatically inputting the current position by the method so-called “global positioning system” or “GPS” as described above the current position is continuously updated (S 1 ). By utilizing the location data of streets and traffic lights and other relevant data CPU  211  recalculates the shortest route to the destination (S 2 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from area  275  of RAM  206  ( FIG. 65 ) (S 3 ). As another embodiment of the present invention by way of utilizing the location data stored in  277  CPU  211  may produce a three-dimensional map by composing the three dimensional objects by method so-called “texture mapping” which are stored in area  276  of RAM  206  ( FIG. 65 ). The two-dimensional map and/or the three-dimensional map is displayed on LCD  201  ( FIG. 1 ) (S 4 ). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of communication device  200  to easily recognize the updated route on LCD  201 . 
       FIG. 72  illustrates the method of finding the shortest location of the desired facility, such as restaurant, hotel, gas station, etc. The voice recognition system is activated in the manner described in  FIG. 67  (S 1 ). By way of utilizing the system a certain type of facility is selected from the options displayed on LCD  201  ( FIG. 1 ). The prepared options can be a) restaurant, b) lodge, and c) gas station (S 2 ). Once one of the options is selected CPU  211  ( FIG. 1 ) calculates and inputs the current position by the method described in  FIG. 68  and/or  FIG. 71  (S 3 ). From the data selected in S 2  CPU  211  scans area  277  or RAM  206  ( FIG. 65 ) and searches the location of the facilities of the selected category (such as restaurant) which is the closest to the current position (S 4 ). CPU  211  then retrieves the relevant two-dimensional map data which should be displayed on LCD  201  from area  275  of RAM  206  ( FIG. 65 ) (S 5 ). As another embodiment of the present invention by way of utilizing the location data stored in  277  CPU  211  may produce a three-dimensional map by composing the three dimensional objects by method so-called “texture mapping” which are stored in area  276  of RAM  206  ( FIG. 65 ). The two-dimensional map and/or the three dimensional map is displayed on LCD  201  ( FIG. 1 ) (S 6 ). The shortest route to the destination is re-highlighted by a significant color (such as red) to enable the user of communication device  200  to easily recognize the updated route on LCD  201 . The voice recognition system is deactivated thereafter (S 7 ). 
       FIG. 73  illustrates the method of displaying the time and distance to the destination. As illustrated in  FIG. 73  CPU  211  ( FIG. 1 ) calculates the current position where the source data can be input from the method described in  FIG. 68  and/or  FIG. 71  (S 1 ). The distance is calculated from the method described in  FIG. 70  (S 2 ). The speed is calculated from the distance which communication device  200  has proceeded within specific duration of time (S 3 ). The distance to the destination and the time left are displayed on LCD  201  ( FIG. 1 ) (S 4  and S 5 ). 
       FIG. 74  illustrates the method of warning and giving instructions when the user of communication device  200  deviates from the correct route. By way of periodically and automatically inputting the current position by the method so-called “global positioning system” or “GPS” as described above the current position is continuously updated (S 1 ). If the current position deviates from the correct route (S 2 ) warnings are given from speaker  216  ( FIG. 1 ) and/or LCD  201  ( FIG. 1 ) (S 3 ). The method described in  FIG. 74  is repeated for certain period of time. If the deviation still exists after such period of time has passed CPU  211  ( FIG. 1 ) initiates the sequence described in  FIG. 70  and calculates the shortest route to the destination and display on LCD  201 . The details of such sequence is as same as the one explained in  FIG. 70 . 
       FIG. 74   a  illustrates the overall operation of communication device  200  regarding the navigation system and the communication system. When communication device  200  receives data from antenna  218  (S 1 ) CPU  211  ( FIG. 1 ) determines whether the data is navigation data, i.e., data necessary to operate the navigation system (S 2 ). If the data received is a navigation data the navigation system described in  FIG. 67  through  FIG. 74  is performed (S 3 ). On the other hand, if the data received is a communication data (S 4 ) the communication system, i.e., the system necessary for wireless communication which is mainly described in  FIG. 1  is performed (S 5 ). 
     Remote Controlling System 
       FIG. 75  through  FIG. 83  illustrates the remote controlling system of communication device  200 . 
     As illustrated in  FIG. 75  communication device  200  is connected to network NT. Network NT may be the interne or have the same or similar structure described in  FIG. 2   a ,  FIG. 2   b  and/or  FIG. 2   c  except “device B” is substituted to “sub-host SH” in these drawings. Network NT is connected to sub-host SH in a wireless fashion. Sub-host SH administers various kinds of equipment installed in building  801 , such as TV  802 , microwave oven  803 , VCR  804 , bathroom  805 , room light  806 , AC  807 , heater  808 , door  809 , and CCD camera  810 . Communication device transfers a control signal to sub-host SH via network NT, and sub-host SH controls the selected equipment based on the control signal. 
     As illustrated in  FIG. 76  communication device  200  is enabled to perform the remote controlling system when the device is set to the home equipment controlling mode. Once communication device  200  is set to the home equipment controlling mode, LCD  201  ( FIG. 1 ) displays all pieces of equipment which are remotely controllable by communication device  200 . Each equipment can be controllable by the following method. 
       FIG. 77  illustrates the method of remotely controlling TV  802 . In order to check the status of TV  802  a specific signal is input from input device  210  ( FIG. 1 ) and communication device  200  thereby sends a check request signal to sub-host SH via network NT. Sub-host SH, upon receiving the check request signal, checks the status of TV  802 , i.e., the status of the power (ON/OFF), the channel, and the timer of TV  802  (S 1 ), and returns the results to communication device  200  via network NT, which are displayed on LCD  201  (S 2 ). Based on the control signal produced by communication device  200 , which is transferred via network NT, sub-host SH turns the power on (or off) (S 3   a ), selects the channel (S 3   b ), and/or sets the timer of TV  802  (S 3   c ). The sequence of S 2  and S 3  can be repeated (S 4 ). 
       FIG. 78  illustrates the method of remotely controlling microwave oven  803 .

       FIG. 85  is a further description of the communication performed between sub-host SH and door  809  which is described in  FIG. 82 . When sub-host SH receives a check request signal as described in  FIG. 82  sub-host SH sends a check status signal which is received by controller  831  via transmitter  830 . Controller  831  checks the status of door lock  832  and sends back a response signal to sub-host SH via transmitter  830  indicating that door lock  832  is locked or unlocked. Upon receiving the response signal from controller  832  sub-host SH sends a result signal to communication device  200  as described in  FIG. 82 . When sub-host SH receives a control signal from communication device  200  as described in  FIG. 82  it sends a door control signal which is received by controller  831  via transmitter  830 . Controller  831  locks or unlocks door lock  832  in conformity with the door control signal. As another embodiment of the present invention controller  831  may owe the task of both sub-host SH and itself and communicate directly with communication device  200  via network NT. 
     As another embodiment of the present invention each equipment, i.e., TV  802 , microwave oven  803 , VCR  804 , bathroom  805 , room light  806 , AC  807 , heater  808 , door lock  809 , and CCD camera  810 , may carry a computer which directly administers its own equipment and directly communicates with communication device  200  via network NT instead of sub-host SH administering all pieces of equipment and communicate with communication device  200 . 
     The above-mentioned invention is also applicable to carriers in general, such as automobiles, airplanes, space shuttles, ships, motor cycles and trains.

       FIG. 86  illustrates the overall structure of the automatic emergency calling system. Communication device  200  is connected to network NT. Network NT may be the internet or have the same or similar structure described in  FIG. 2   a ,  FIG. 2   b  and/or  FIG. 2   c . Network NT is connected to automobile  835  thereby enabling automobile  835  to communicate with communication device  200  in a wireless fashion. Emergency center EC, a host computer, is also connected to automobile  835  in a wireless fashion via network NT. Airbag  838  which prevents persons in automobile  835  from being physically injured or minimizes such injury in case traffic accidents occur is connected to activator  840  which activates airbag  838  when it detects an impact of more than certain level. Detector  837  sends an emergency signal via transmitter  836  when activator  840  is activated. The activation signal is sent to both emergency center EC and communication device  200 . In lieu of airbag  838  any equipment may be used so long as such equipment prevents from or minimizes physical injuries of the persons in automobile  835 . 
       FIG. 87  illustrates the overall process of the automatic emergency calling system. Detector  837  periodically checks activator  840  (S 1 ). If the activator  840  is activated (S 2 ) detector  837  transmits an emergency signal via transmitter  836  (S 3   a ). The emergency signal is transferred via network NT and received by emergency center EC and by communication device  200  (S 3   b ). 
     As another embodiment of the present invention the power of detector  837  may be usually turned off, and activator  840  may turn on the power of detector  837  by the activation of activator  840  thereby enabling detector  837  to send the emergency signal to both emergency center EC and to communication device  200  as described above. 
     This invention is also applicable to any carriers including airplanes, space shuttles, ships, motor cycles and trains.
