Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a portable or mobile radio device such as portable or cellular phones, portable information terminals, and so on. More particularly, the invention relates to a portable or mobile radio device having a pointer movably displayed on a screen. 
   2. Description of the Related Art 
   Recently, mobile communication devices or terminals such as cellular phones, which have a small display screen, have been used not only for telephone conversation but also for transmission and reception of e-mail messages and reading/viewing homepages or sites by accessing specific WWW (World Wide Web) servers on the Internet. On the display screen of the terminal of this type, action items or menu items are usually formed or displayed for the purpose of facilitating the choice of desired or required items, such as personal information (e.g., telephone directory), e-mail messages received or transmitted, and the character and/or graphic information obtained from the WWW servers on the Internet. If a user chooses one of the items displayed on the screen and instructs the terminal to execute a function or functions corresponding to the item thus chosen, the terminal will conduct the desired function or functions. 
   For example, when a user makes a telephone call with a mobile communication terminal of this type, the user operates the terminal in such a way that his/her telephone directory is displayed on the screen and then, a desired person and a corresponding telephone number are chosen from the listing of the directory using the pointer movably displayed on the screen. Thereafter, the user presses an execution button (i.e., a calling button). Thus, the user will be able to make a telephone call to the person the user has chosen this time. 
   Moreover, if the user moves the pointer to a desired one of the menu or action items on the screen and instructs the terminal to execute a function or functions corresponding to the item thus chosen, the user can open a window for creating an e-mail message and transmitting the same, or can brows other WWW servers or Internet sites as desired. 
   However, the above-described prior-art mobile communication terminals have the following problems. 
   Specifically, the display screen is small because the terminal itself is small-sized for mobility. The pointer is moved on the screen analogous to the operation of manipulation buttons. Therefore, it is difficult for the user to recognize the menu items displayed on the screen and to choose a desired one of the items with the sense of sight only. For example, it is not easy for the user to correctly choose a 2×2 dot area of the menu item on the screen with the pointer Moreover, if the user is poor in eyesight, the user is unable to manipulate the pointer as desired. 
   SUMMARY OF THE INVENTION

   The controller section  34  comprises a CPU (Central Processing Unit) having a ROM (Read-Only Memory) for storing a control program therein and a RAM (Random-Access Memory) used as a temporary memory region. The section  34  controls each element of the device  10  as necessary. In particular, the section  34  controls the movement of the pointer and the scroll of information displayed on the screen of the display section  35  according to the manipulation applied by the user by way of the manipulator section  39 . 
   The display section  35  comprises a LCD (Liquid-Crystal Display) device that provides the above-described display screen. 
   The audio processor section  36  comprises an audio CODEC (COder-DECoder), an A(analog)/D(digital) converter circuit, a D(digital)/A(analog) converter circuit, and so on. 
   The manipulator section  39  comprises a set of manipulation buttons to be pressed by the user. 
   The memory section  40  comprises a rewritable nonvolatile memory, which is used for temporarily storing reception data, and for storing data (e.g., data for an electronic address book) registered by the user, and so on. The data stored in the section  40  is read out by the controller section  34  and displayed on the screen of the display section  35  according to the necessity. 
     FIG. 6  shows the appearance or exterior of the mobile communication terminal  10  according to the first embodiment of the invention. As shown in  FIG. 6 , the display screen of the display section  35 , which is indicated by the reference numeral  351 , is formed in the upper part of the front surface of the terminal  10 . The manipulator section  39  is located in the lower part of the front surface of the terminal  10 . 
   The section  39  includes a set of moving buttons  391  for scrolling the information displayed on the screen  351  and a set of input keys  392  for inputting numeric or characteristic data into the terminal  10 . As the set of moving buttons  391 , an upward moving button  3911 , a leftward moving button  3912 , a rightward moving button  3913 , and a downward moving button  3914  are provided here. If the user presses one of the four buttons  3911  to  3914 , the information displayed on the screen  351  is scrolled by a specific distance (e.g., a length for one dot) in a direction corresponding to the button pressed. The scrolling distance varies according to the time when the button is being pressed. As explained later, the set of the buttons  3911  to  3914  are used for moving the pointer on the screen  351  as well. 
   Not only necessary information for telephone conversation but also e-mail messages received, character and/or graphic data downloaded, telephone number-address lists registered, and so on, can be displayed on the screen  351 . 
   Next, the operation of the mobile communication terminal  10  according to the first embodiment is explained below with reference to  FIG. 1 .  FIG. 1  shows the configuration and operation the terminal  10  relating to the movement of the pointer. 
   The terminal  10  is designed in such a way that specific actions are carried out corresponding to the movement of the pointer on the screen  351 . These specific actions are practically realized under the control of the control program stored in the controller section  34 . The controller section  34  has a pointer action controller formed by the control program. 
   As shown in  FIG. 1 , the pointer action controller of the controller section  34  comprises a pointer-position information acquisition section  11 , an action area &amp; required action data acquisition section  12 , an inward/outward action judgment section  13 , an inward action instruction section  14 , an outward action instruction section  15 , an action control section  16 , and an action area &amp; corresponding action definition section  17 . 
   The pointer-position information acquisition section  11  acquires the position information of the pointer displayed on the screen  351 . 
   The action area &amp; required action data acquisition section  12  acquires the position data of an action area (which corresponds to a first area) displayed on the screen  351  and the data of a required action corresponding to the said action area. 
   The inward/outward action judgment section  13  judges whether or not a movement of the pointer on the screen  351  from the inside of the action area to the outside thereof (which corresponds to a second area), or a movement of the pointer on the screen  351  from the outside of the action area to the inside thereof has been carried out. 
   The inward action instruction section  14  acquires the data of the action caused when the pointer is moved from the outside of the action area to its inside. Then, the section  14  instructs the action controller section  16  to execute a predetermined action corresponding to the said movement of the pointer. 
   The outward action instruction section  15  acquires the data of the action caused when the pointer is moved from the inside of the action area to its outside Then, the section  15  instructs the action controller section  16  to execute a predetermined action corresponding to the said movement of the pointer. 
   The action controller section  16  receives the instruction from the inward action instruction section  14  or the outward action instruction section  15 , and controls the execution of the action thus instructed by the section  14  or  15 . 
   The action area &amp; corresponding action definition section  17  defines the action area on the screen  351  and its corresponding actions to be carried out according to the instruction from the inward or outward action instruction section  14  or  15 . 
   Here, the “action area” is an area formed or displayed on the screen  351  where a predetermined action such as vibration, sound reproduction, rumbling, or the like is carried out if the pointer is placed correctly in the “action area”. The “action area” is usually formed or defined in such a way as to have approximately the same position, size, and shape as those of an area for specifying or designating a desired telephone number from the list in the phone book, an area for creating and/or transmitting/replying e-mail messages, and an area for designating the location of a desired WWW server (i.e., the URL (Universal Resource Locator) of a desired site on the Internet), or the like. If the user chooses one of these areas and instructs the terminal  10  to execute the corresponding function to the area thus chosen, information processing is conducted in the terminal  10  according to the user&#39;s choice. 
   Next, the overall operation flow of the pointer action controller of the controller section  34  is explained below with reference to  FIG. 1 . 
   First, when the pointer is started to move on the screen  351 , the pointer-position acquisition section  11  is called or activated Then, the section  11  acquires the position data of the pointer on the screen  351  and calls the action area &amp; required action data acquisition section  12 . Thereafter, the section  12  acquires the position data of the action area on the screen  351  and the data of corresponding actions to the said action area. The corresponding actions to the action area are defined in advance by the action area &amp; corresponding action definition section  17 . After acquiring the data of the action area and the corresponding actions, the section  12  calls the inward/outward action judgment section  13 . 
   In response, the inward/outward action judgment section  13  judges whether or not the pointer has been moved from the inside of the action area to the outside thereof or moved from the outside of the action area to the inside thereof. If the pointer has been moved from the outside of the action area to the inside thereof, the section  13  calls the inward action instruction section  14 , and transmits the action data corresponding to the action area in question to the section  14 . On the other hand, if the pointer has been moved from the inside of the action area to the outside thereof, the section  13  calls the outward action instruction section  15 , and transmits the action data corresponding to the action area in question to the section  15 . If the pointer has been moved in the inside of the action or in the outside thereof, the operation flow is finished directly. 
   When the pointer has been moved from the outside of the action area to the inside thereof, the inward action instruction section  14  is called Thereafter, the section  14  acquires the action data corresponding to the said action of the pointer and then, instructs the action control section  16  to execute an action according to the said inward action of the pointer. On the other hand, when the pointer has been moved from the inside of the action area to the outside thereof, the outward action instruction section  15  is called. Thereafter, the section  15  acquires the action data corresponding to the said action of the pointer and then, instructs the action control section  16  to execute an action according to the said outward action of the pointer. 
   Finally, the action controller section  16  receives the action data transmitted from the inward action instruction section  14  or the outward action instruction section  15  and then, controls the execution of the action instructed by the section  14  or  15 . Thereafter, the operation flow is completed. 
     FIG. 2  schematically shows the displayed image of the screen  351  of the terminal  10  according to the first embodiment, where an arrow-shaped pointer  21 , a rectangular button  22  labeled “BUTTON A”, and a rectangular action area  23  are displayed and formed. 
   Here, the boundary of the action area  23  is in accordance with the contour or outline of the button  22 , in other words, the action area  23  is entirely overlapped with the button  22 . However, the boundary of the action area  23  may not be in accordance with the contour or outline of the button  22 . The pointer  21  is formed to be movable on the whole screen  351  and used for choosing or pointing the button  22  and other buttons (not shown). The pointer  21  is designed in such a way as to be moved in all directions on the screen  351  by pressing the set of the moving buttons  391  provided for scrolling the displayed information on the screen. Specifically, when the user presses the upward or downward moving button  3911  or  3914 , the pointer  21  is moved upwardly or downwardly from the current position, respectively. Similarly, when the user presses the rightward or leftward movement button  3912  or  3913 , the pointer  21  is moved to the right or left from the current position, respectively. The moving distance of the pointer  21  varies according to the time when the button  3911 ,  3912 ,  3913 , or  3914  is being pressed. By adjusting the pressing time of the button  3911 ,  3912 ,  3913 , or  3914 , the user can move the pointer  21  to his/her desired position on the screen  351  optionally. 
   If the user operates the buttons  3911 ,  3912 ,  3913 , and  3914  in such a way as to locate the pointer  21  on the button  22  to thereby choose the same and then, presses an execution button (not shown), specific information processing that has been defined for the button  22  in advance is carried out. For example, if the function assigned to the button  22  is to make a phone call to a person whom the user chooses, the user can make a phone call to the person he/she has chosen from the list of the phone book. It the function assigned to the button  22  is to deal with e-mail, the user can create and transmit new e-mail messages, receive e-mail messages transmitted to the user, recall desired e-mail messages received for reply, and delete unnecessary e-mail messages received. If the function assigned to the button  22  is to read and/or view Internet sites, the user can optionally access desired sites on the Internet the user has chosen or designated in a known way. 
   Points A, B, C, and D shown in  FIG. 2  are established for explanation of this embodiment. The points A and D are located at different positions outside the action area  23  and button  22 , in other words, the points A and D do not overlap with the area  23  and the button  22 . The points B and C are located at different positions in the action area  23  and the button  22 , in other words, the points B and C are overlapped with the area  23  and the button  22 . 
   Two specific actions are assigned to the action area  23 . One of the actions assigned is to start a predetermined vibration of the terminal  10 , which is carried out at the time when the pointer  21  is moved from the outside of the action area  23  to the inside thereof. The action to start the vibration of the terminal  10  is termed the “inward action”. The other of the actions assigned is to stop the predetermined vibration of the terminal  10 , which is carried out at the time when the pointer  21  is moved from the inside of the action area  23  to the outside thereof The action to stop the vibration of the terminal  10  is termed the “outward action”. 
   Here, it is supposed that the pointer  21  is initially located at the point A and the, it is successively moved to the points B, C, and D. Moreover, it is supposed that the pointer  21  is moved straight from the point A to point B with a single action, from the point B to point C with a single action, and from the point C to point D with a single action. 
   When the pointer  21  is located at the point A, no action is started When the pointer  21  is moved from the point A to the point B, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the outside of the action area  23  to the inside thereof across the border of the area  23 , in other words, the “inward action” of the pointer  21  has been conducted. Thereafter, the section  13  sends the inward action instruction section  14  an order to start the predetermined vibration operation of the terminal  10 . In response to the order, the section  14  instructs the action control section  16  to control the execution of the “inward action”. Under the control of the section  16 , the vibration operation of the terminal  10  is started. 
   When the pointer  21  is moved from the point B to the point C, the pointer  21  has no action between the outside of the action area  23  and the inside thereof through the border of the area  23 . Thus, no other action is caused and as a result, the vibration operation of the terminal  10  continues. 
   When the pointer  21  is moved from the point C to the point D, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the inside of the action area  23  to the outside thereof across the border of the area  23 , in other words, the “outward action” of the pointer  21  has been carried out. Thereafter, the section  13  sends the outward action instruction section  15  an order to stop the predetermined vibration operation of the terminal  10 . In response to the order, the section  15  instructs the action control section  16  to control the start of the “outward action”. Under the control of the section  16 , the vibration operation of the terminal  10  is stopped. 
   Accordingly, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate appropriately the set of the moving buttons  391  until the vibration operation of the terminal  10  starts and to stop the manipulation of the buttons  391  immediately after the vibration operation has been started. If the user mistakenly manipulates the pointer  21  and thus, the pointer  21  is passed through the button  22 , the vibration operation is stopped when the pointer  21  is moved to the outside of the action area  23 , i.e., the button  22 . Therefore, the user can immediately recognize his/her manipulation operation as a mistake or not easily. As a result, the operability of the terminal  10  is improved; in other words, the terminal  10  can be operated more easily. 
   In the above-described first embodiment, the start of vibration of the terminal  10  is defined as the “inward action” while the stop of the same vibration is defined as the “outward action”. However, reproduction of sound may be used for this purpose. Specifically, the start of reproduction of a sound may be defined as the “inward action” while the stop of the reproduction of the said sound may be defined as the “outward action”. For example, to start reproduction of a predetermined, prolonged sound of “twee” is assigned to the “inward action”, which is carried out at the time when the pointer  21  is moved from the outside of the action area  23  to the inside thereof. On the other hand, to stop the reproduction of the said predetermined sound is assigned to the “outward action”, which is carried out at the time when the pointer  21  is moved from the inside of the action area  23  to the outside thereof. 
   In this case, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate the set of the moving buttons  391  until the reproduction operation of the sound of “twee” starts and to stop the manipulation of the buttons  391  immediately after the reproduction operation has started. It the user mistakenly manipulates the pointer  21  and thus, the pointer  21  is passed through the button  22 , the sound-reproduction operation is stopped when the pointer  21  is moved to the outside of the action area  23  (i.e., the button  22 ) across the border of the area  23 . Therefore, the user can immediately recognize his/her manipulation as a mistake or not easily. As a result, the operability of the terminal  10  is improved; in other words, the terminal  10  can be operated more easily. 
   Moreover, the start of reproduction of the sound A may be defined as the “inward action” while the start of reproduction of the sound B different from the sound A may be defined as the “outward action”. In this case, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate the set of the moving buttons  391  until the reproduction operation of the sound A starts and to stop the manipulation of the buttons  391  immediately after the reproduction operation of the sound B has started. If the user mistakenly manipulates the pointer  21  and thus, the pointer  21  is passed through the button  22 , the reproduced sound is changed from the sound A to the sound B when the pointer  21  is moved to the outside of the action area  23  (i.e., the button  22 ) across the border of the area  23 . Therefore, the user can immediately recognize his/her manipulation as a mistake or not easily. As a result, the operability of the terminal  10  is improved; in other words, the terminal  10  can be operated more easily. 
   Furthermore, the following variation is applicable if the terminal  10  is designed in such a way as to cause its vibration in different ways. Specifically, the start of a vibration C may be defined as the “inward action” while the start of a vibration D different from the vibration C may be defined as the “outward action”. In this case, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate the set of the moving buttons  391  until the vibration C starts and to stop the manipulation of the buttons  391  immediately after the vibration D has started. If the user mistakenly manipulates the pointer  21  and thus, the pointer  21  is passed through the button  22 , the generated vibration is changed from the vibration C to the vibration D when the pointer  21  is moved to the outside of the action area  23 . Therefore, the user can immediately recognize his/her manipulation as a mistake or not easily. As a result, the operability of the terminal  10  is improved; in other words, the terminal  10  can be operated more easily. 
   The same advantages are obtainable if vibration of the terminal  10  and reproduction of sound are combined together as the “inward action” and/or the “outward action”. For example, the start of reproduction of a “sound” may be defined as the “inward action” while the start of a “vibration” may be defined as the “outward action”. The start of a “vibration” may be defined as the “inward action” while the start of reproduction of a “sound” may be defined as the “outward action”. The start of generation of a “vibration” and the reproduction of a “sound” may be combined together as the “inward action”. In this case, the user can recognize more easily whether his/her manipulation of the moving buttons  391  is made correctly or not by way of existence/absence or change of the vibration of the terminal  10  and/or the reproduction of sound. Therefore, the operability or the terminal  10  is improved furthermore. 
   Second Embodiment  
     FIG. 3  shows a mobile radio device according to a second embodiment of the invention, which is designed as a mobile telephone terminal like the first embodiment. 
   The terminal according to the second embodiment comprises the same configuration as the terminal  10  according to the first embodiment shown in  FIGS. 1 ,  2 ,  5 , and  6 , except for the configuration and operation of the pointer action controller of the controller section  34 , which is formed by a control program. Therefore, the detailed description about the same configuration and operation is omitted here for the sake of simplification of description. 
   As shown in  FIG. 3 , the pointer action controller comprises the pointer-position information acquisition section  11 , the action area &amp; required action data acquisition section  12 , the inward/outward action judgment section  13 , the inward action instruction section  14 , the action controller section  16 , and the action area &amp; corresponding action definition section  17 . The inward action instruction section  15  is not provided and therefore, the operation flow is completed directly if the pointer  21  is moved from the outside of the action area  23  (i.e., the button  22 ) to the inside thereof. 
   The pointer-position information acquisition section  11 , the action area &amp; required action data acquisition section  12 , the inward/outward action judgment section  13 , the inward action instruction section  14 , the action controller section  16 , and the action area &amp; corresponding action definition section  17  are the same as those used in the first embodiment. Therefore, no explanations for them are provided here. 
   Since the outward action instruction section  15  is not provided, only the “inward action” is assigned to the action area  23 . Here, the start of reproduction of a short sound “feep” or “beep” may be defined as the “inward action” while no action is defined as the “outward action”. 
   Next, the overall operation flow of the pointer action controller of the mobile communication terminal according to the second embodiment is explained below with reference to  FIGS. 2 and 3 . 
   When the pointer  21  is located at the point A, no action is started. When the pointer  21  is moved from the point A to the point B, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the outside of the action area  23  to the inside thereof, in other words, the “inward action” of the pointer  21  has been made. Thereafter, the section  13  sends the inward action instruction section  14  an order to start the reproduction of the predetermined short sound “feep” or “beep”. In response to the order, the section  14  instructs the action control section  16  to control the execution of the “inward action”. Under the control of the section  16 , the reproduction operation of the short sound “feep” or “beep” is carried out twice. 
   When the pointer  21  is moved from the point B to the point C, the pointer  21  has no action across the border of the action area  23 . Thus, no action is caused. 
   When the pointer  21  is moved from the point C to the point A, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the inside of the action area  23  to the outside thereof, in other words, the “outward action” of the pointer  21  has been conducted. In this embodiment, the outward action instruction section  15  is not provided and no action is defined as the “outward action”. Thus, no action or operation is conducted at this stage. 
   Accordingly, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate the set of the moving buttons  391  until the reproduction operation of the predetermined sound starts and to stop the manipulation of the buttons  391  immediately after the reproduction operation has started. Therefore, the user can immediately recognize his/her manipulation as a mistake or not easily. As a result, the operability of the terminal is improved like the first embodiment; in other words, the terminal  10  can be operated more easily. 
   In the above-described second embodiment, the start of reproduction of the predetermined short sound is defined as the “inward action” while no operation is defined as the “outward action”. However, vibration of the terminal or reproduction of a prolonged sound as used in the above-described first embodiment may be used as the “inward action”. Vibration of the terminal and reproduction of a sound may be simultaneously used for this purpose. In this case, the same advantages as those in the first embodiment are obtainable. 
   Third Embodiment  
     FIG. 4  shows a mobile radio device according to a third embodiment of the invention, which is designed as a mobile telephone terminal like the first and second embodiments. 
   The terminal according to the third embodiment comprises the same configuration as the terminal  10  according to the first embodiment shown in  FIGS. 1 ,  2 ,  5 , and  6 , except for the configuration and operation of the pointer action controller of the controller section  34 , which is formed by a control program. Therefore, the detailed description about the same configuration and operation is omitted here for the sake of simplification of description. 
   As shown in  FIG. 4 , the pointer action controller comprises the pointer-position information acquisition section  11 , the action area &amp; required action data acquisition section  12 , the inward/outward action judgment section  13 , the outward action instruction section  15 , the action controller section  16 , and the action area &amp; corresponding action definition section  17 . The inward action instruction section  14  is not provided and therefore, the operation flow is completed directly if the pointer  21  is moved from the outside of the action area  23  (i.e., the button  22 ) to the inside thereof. 
   The pointer-position information acquisition section  11 , the action area &amp; required action data acquisition section  12 , the inward/outward action judgment section  13 , the outward action instruction section  15 , the action controller section  16 , and the action area &amp; corresponding action definition section  17  are the same as those used in the first embodiment. Therefore, no explanations for them are provided here. 
   Since the inward action instruction section  14  is not provided, only the “outward action” is assigned to the action area  23 . Here, the start of reproduction of a short sound “feep” or “beep” may be defined as the “outward action” while no action is defined as the “inward action”. 
   Next, the overall operation flow of the pointer action controller of the mobile communication terminal according to the third embodiment is explained below with reference to  FIGS. 2 and 4 . 
   When the pointer  21  is located at the point A, no action is started. When the pointer  21  is moved from the point A to the point B, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the outside of the action area  23  to the inside thereof, in other words, the “inward action” of the pointer  21  has been conducted. Since the inward action instruction section  14  is not provided and no action is defined as the “inward action”, no action or operation is conducted at this stage. 
   When the pointer  21  is moved from the point B to the point C, the pointer  21  has no action across the border of the action area  23 . Thus, no action is caused. 
   When the pointer  21  is moved from the point C to the point D, the inward/outward action judgment section  13  judges that the pointer  21  has been moved from the inside of the action area  23  to the outside thereof, in other words, the “outward action” of the pointer  21  has been conducted. Thereafter, the section  13  sends the outward action instruction section  15  an order to conduct the predetermined vibration operation of the terminal  10 . In response to the order, the section  15  instructs the action control section  16  to control the execution of the “outward action”. Under the control of the section  16 , the reproduction operation of the short sound “feep” or “beep” is carried out twice. 
   Accordingly, if the user wants to move the pointer  21  to the button  22 , it is sufficient for the user to manipulate the set of the moving buttons  391  in such a way that the reproduction operation of the predetermined sound does not start. Therefore, the user can immediately recognize his/her manipulation as a mistake or not easily by way of hearing the sound “feep” or “beep”. As a result, the operability of the terminal is improved like the first and second embodiments; in other words, the terminal can be operated more easily. 
   In the above-described third embodiment, the start of reproduction of the predetermined short sound is defined as the “outward action” while no operation is defined as the “inward action”. However, in the same way as the second embodiment, vibration of the terminal or reproduction of another sound may be used as the “outward action”. Vibration of the terminal and reproduction of a sound may be simultaneously used for this purpose. In this case, the same advantages as those in the first embodiment are obtainable. 
   Other Embodiments  
   It is needless to say that the invention is not limited to the above-described first to third embodiments. In the above-described first to third embodiments, reproduction of a sound or sounds and/or generation of a vibration or vibrations are assigned to the “inward action” and/or the “outward action”, respectively. However, the invention is not limited to these examples. Approximately the same advantages are obtainable if any other action is assigned to the “inward action” and/or the “outward action”. 
   For example, emission of visible light from the screen  351  may be employed for this purpose, which can be realized by using a known technique, for example, by changing the intensity of the emitted light from the screen  351 . Emission of visible light from the screen  351  may be used solely or combined to reproduction of a sound or sounds and/or generation of a vibration or vibrations. In the case where emission of visible light, reproduction of a sound or sounds, and generation of a vibration or vibrations are combined together, the count of ways to confirm or recognize whether the choice of the button  22  is correct or not is increased. Therefore, the operability of the terminal or device is improved furthermore. Additionally, there is an additional advantage that the improved operability does not degrade even if the terminal or device is located in a place where the information on the screen  351  is hard to make out with naked eyes. 
   As the sound for the “outward action” and/or the “inward action”, a specific “melody” may be used. A melody may be used solely or combined to a short sound “feep” or “beep” or a prolonged sound “twee” The sound reproduction or vibration may be automatically finished after a predetermined constant period has passed, or may continue until corresponding information processing is executed or other action is carried out. In these cases, the same advantage is obtainable. 
   Additionally, although the single button  22  is displayed on the screen  351  in the first to third embodiments, a plurality of buttons may be simultaneously displayed on the screen  351 , as shown in  FIG. 7A . In the example of  FIG. 7A , three buttons  22   a ,  22   b , and  22   c  and three action areas  23   a ,  23   b , and  23   c  are displayed on the screen  351 . The action areas  23   a ,  23   b , and  23   c  are formed in such a way as to be entirely overlapped with the buttons  22   a ,  22   b , and  22   c , respectively. In this case, an additional advantage that the range of selectable information is expanded is obtainable. 
   In the above-described first to third embodiments, the object of moving the pointer  21  is to choose the window of designating a person the user wants to make a phone call, dealing e-mail, or designating the Internet site. However, moving of the pointer  21  may be used for any other purposes. For example, it may be used for operating a game on the screen  351 , or designating a desired location or point on a map displayed on the screen  351 . It may be used for selecting each function built in the terminal or device in the menu displayed on the screen  351 . 
   When a plurality of buttons is simultaneously displayed on the screen  351 , different actions or functions may be assigned to the respective buttons. For example, “phone book”, “e-mail”, “WWW browser”, “game”, various information, “additional services”, and so on, may be simultaneously displayed in the menu on the screen  351 . In this case, different sounds may be assigned to the respective buttons. Sounds used for a part of the buttons may be different while sounds used for the remainder may be the same. 
   A specific sound may be assigned to each of the buttons in such a way as to suggest or denote the content of information processing corresponding to the button. For example, if the pointer  21  is moved to the inside of the button  22  (i.e., the action area  23 ) labeled “phone book”, a voice of “phone book” or “to make a phone call” may be reproduced. In this case, the user&#39;s choice S about the buttons can be easily recognized and as a result, the operability of the terminal is improved furthermore. 
   If the pointer  21  is moved to the inside of the button  22  (i.e., the action area  23 ) labeled “creating e-mail”, “replying e-mail”, or “deleting e-mail”, it is preferred to reproduce a voice of “to make an e-mail message”, “to reply an e-mail message to Mr. or Ms. A”, or “to delete an e-mail message designated”, respectively. Similarly, if a recipient of a phone call is designated, a voice pronouncing the name of the recipient or the like may be reproduced. For example, a voice of “to make a phone call to Mr. or Ms. B” or “to communicate with the C company” may be reproduced. If the pointer  21  is used to designate a desired location on a map on the screen  351 , a voice pronouncing the name of the location may be reproduced. If the pointer  21  is used to designate a URL of a desired Internet site, a voice of “to access the site or homepage of D” or “to display the information at the site or homepage of E” may be reproduced. In this way, it is preferred to reproduce an appropriate voice denoting the content of the information processing corresponding to the button  22 . In these cases, the user&#39;s choice about the buttons or the contents of the information to be processed can be easily recognized and as a result, the operability of the terminal is improved furthermore. 
   In the above-described embodiments, the pointing device is formed by the set of the moving buttons  3911 ,  3912 ,  3913 , and  3914 . However, any other pointing device such as a touch-pad, trackball, a joystick, or a set of buttons for bi-directional movements may be used for this purpose. In this case, there is an additional advantage that the operability of the pointer itself is improved. Additionally, a “cursor” designed for only choosing one of the information processing items displayed on the screen  351  may be used instead of the arrow-shaped pointer  21 , where the movable range of the cursor is limited in the items thus listed, as shown in  FIG. 7B . In the example of  FIG. 7B , a menu  51  including selectable eight items (i.e., item a to item h) is displayed on the screen  351  and at the same time, a rectangular cursor  52  (which serves as the above-described pointer) is displayed. The cursor  52  is movable in the menu  51  and used to choose one of the eight items When the cursor  52  is moved across the boundary of the adjoining items, a notification operation using vibration, sound, and/or light is carried out for the user. This is similar to the above-described first to third embodiments. In this case, the same advantages as those of the above-described embodiments are obtainable. 
   Although the above-described mobile radio devices of the first to third embodiments are designed as a mobile telephone terminal, they may be designed as a terminal for so-called PHS (Personal Handyphone System). 
   While the preferred forms of the present invention have been described, it is to be understood that modifications will be apparent to those skilled in the art without departing from the spirit of the invention. The scope of the present invention, therefore, is to be determined solely by the following claims.
