  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a communication system, a communication method thereof, and a portable terminal that are less likely to be viewed by a third party through a key arrangement, and that makes it difficult for a third party to leak key input information. There is.

  In order to solve the above-mentioned problem, a communication system according to the present invention includes a mobile terminal, a base station, and an input support system. When one key is pressed on the mobile terminal, the key press information is Transmitted to the input support system via the base station, and predetermined key layout information is transmitted from the input support system to the mobile terminal via the base station, and the mobile terminal responds to the key layout information The input support system includes key arrangement information transmitting means for transmitting different key arrangement information every time the key pressing information is received, and is provided in the portable terminal. The display screen is a touch sensor type display screen, and the display screen displays the key arrangement when an object is brought close, and the key arrangement is hidden when the object is released. Characterized in that it comprises a display control means to.

  The communication method according to the present invention includes a mobile terminal, a base station, and an input support system. When one key is pressed on the mobile terminal, the key press information is transmitted via the base station. The key arrangement information is transmitted to the input support system, and the predetermined key arrangement information is transmitted from the input support system to the portable terminal via the base station, and the key arrangement corresponding to the key arrangement information is displayed on the display screen. A communication method in a communication system displayed on the display screen, wherein the input support system includes a key layout information transmission step of transmitting different key layout information each time the key press information is received, and the display screen provided in the portable terminal Is a touch sensor type display screen, the display screen displays the key arrangement when an object is brought close, and the key arrangement is hidden when the object is released. Characterized in that it comprises a display control step that.

  The mobile terminal according to the present invention includes a mobile terminal, a base station, and an input support system. When one key is pressed on the mobile terminal, the key press information is transmitted via the base station. The key arrangement information is transmitted to the input support system, and the predetermined key arrangement information is transmitted from the input support system to the portable terminal via the base station, and the key arrangement corresponding to the key arrangement information is displayed on the display screen. The mobile terminal in the communication system displayed on the display screen, wherein the key support information is transmitted from the input support system to the mobile terminal, and the display screen provided on the mobile terminal is A display screen of a touch sensor type, wherein the display screen displays the key arrangement when an object is brought close to the display screen and hides the key arrangement when the object is released. Characterized in that it comprises a stage.

  Next, the operation of the present invention will be described. The portable terminal according to the present invention has a display screen on which an array of keys is displayed. In addition, information can be input by pressing any key displayed on the display screen.

  First, when a user (user) presses one key, the key press information is transmitted to the wireless portable terminal input support system via the base station. The wireless portable terminal input support system that has received the key press information transmits new key arrangement information to the wireless portable terminal via the base station.

  The wireless portable terminal receives this new key layout information and displays it on the display screen. As a result, the user performs the second key input using a key arrangement different from the first key input. Similarly, the third and subsequent key inputs are performed using different key arrangements.

  By the way, conventionally, since the current key layout is continuously displayed until the key layout changes to another key layout, there is a possibility that the key layout may be viewed by a third party during that time. Therefore, there is a risk of guessing which key is pressed from the position of the user's finger (without looking directly at the key).

  In contrast, in the present invention, one of the keys has a function different from that of the other keys. The key (hereinafter, this key is referred to as “sensor key”) is to display other keys only when a finger or an object is brought close to the sensor key. Therefore, since pressing of a numeric or symbol key is performed in a non-display state, there is little possibility that the key arrangement is viewed by a third party. Since the user presses a key from a key display screen whose key layout is not displayed, it is necessary to remember in advance the position of the key to be pressed.

  According to the present invention, since the above-described configuration is included, there is little possibility that the key arrangement will be looked into by a third party, thereby making it possible to make it difficult for the third party to leak the information input by the key.

  The best mode of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram of the best mode of a communication system according to the present invention. Referring to FIG. 1, the best mode of a communication system according to the present invention includes a wireless mobile terminal 1, which is an example of a mobile terminal, a base station 2, and a wireless mobile terminal input support system 3.

  Further, the wireless portable terminal input support system 3 includes a communication unit 4, a control unit 5, a processing unit 6, and a database unit 7.

  First, the configuration of the wireless portable terminal 1 will be described. FIG. 2 is a configuration diagram of an example of the wireless portable terminal 1. Referring to FIG. 1A, the wireless portable terminal 1 is a foldable portable terminal as an example, and includes a display screen 1a in one casing and a display screen 1b in the other casing.

  Character or image information is displayed on the display screen 1a. The key layout is displayed on the display screen 1b. In addition, information can be input by pressing any key displayed on the display screen 1b. In other words, the display screen 1b is a so-called “touch sensor” type display screen.

  More specifically, when a key on the display screen 1b is pressed with an object such as a finger, key pressing information indicating that the key has been pressed is transmitted to the wireless portable terminal input support system 3 via the base station 2. The

  The wireless portable terminal 1 itself in FIG. 5B is the same as that in FIG. 5A, and the key layout on the display screen 1d of the other housing is the key on the display screen 1b in FIG. It is different from the sequence. As will be described later, the key arrangement on the display screen 1b is changed to the key arrangement on the display screen 1d based on the new key arrangement transmitted from the wireless portable terminal input support system 3.

  Next, the configuration of the base station 2 will be described. The base station 2 exchanges information with the wireless portable terminal 1. Information is also exchanged with the communication unit 4 of the wireless portable terminal input support system 3.

  Next, the configuration of each part of the wireless portable terminal input support system 3 will be described.

  The communication unit 4 acquires input information obtained from the wireless portable terminal 1 via the base station 2. The control unit 5 controls various information obtained from the communication unit 4 and the processing unit 6. Based on information from the control unit 5, the processing unit 6 performs a process for determining a key arrangement to be displayed on the wireless portable terminal 1. The database unit 7 stores information about the key layout displayed on the wireless portable terminal 1.

  Next, the operation of the best mode of the communication system according to the present invention will be described. FIG. 3 is a schematic diagram showing a process of changing the key layout displayed on the display screen of the best mode of the communication system according to the present invention, and FIG. 4 is a flowchart showing the operation of the best mode of the communication system.

  3A to 3D, among the keys of the display screens 1b, 1d, 1f, and 1h, the upper leftmost key is the sensor key 11, and has a function different from that of the other keys. That is, when a finger or object is brought close to this key, other keys (numbers, alphabets, symbols, etc.) are displayed, and when a finger or object is moved away from this key, other keys (numbers, alphabets, symbols, etc.) are hidden. To do. The position of this key is not limited to the left end of the uppermost stage, and the position is arbitrary.

  First, a text prompting the input of a personal identification number is output on the display screen 1a of the wireless portable terminal 1 (step S1 in FIG. 4 and FIG. 3A). At this time, nothing is displayed on the display screen 1b of the wireless portable terminal 1 (FIG. 3A).

  Next, an object such as a finger or a touch pen is brought close to the sensor key 11 on the display screen 1d of the wireless portable terminal 1 (step S2 in FIG. 4 and FIG. 3B).

  When an object is brought close to the sensor key 11, a key arrangement in which numbers, alphabets, symbols, and the like are randomly arranged is displayed on the display screen 1d (step S3 in FIG. 4 and FIG. 3B). At this time, the sensor key 11 can be sensed by a method such as thermal sensing, power sensing, or pressure sensing.

  Next, when an object such as a finger is released from the sensor key 11, the key arrangement is not displayed again (step S4 in FIG. 4 and FIG. 3C). That is, the key arrangement is displayed on the display screen only when an object such as a finger is approaching the sensor key 11.

  Next, the location where the key that the user wants to press is displayed (step S5 in FIG. 4 and FIG. 3C). At this time, since the key arrangement on the display screen 1f is not displayed, it is necessary for the user to store in advance where the key to be pressed is when the key arrangement is displayed in step S3.

  Next, information (hereinafter referred to as “key pressing information”) notifying that the key has been pressed is transmitted from the wireless portable terminal 1 to the base station 2 (step S6 in FIG. 4). At this time, a symbol (“*” as an example) indicating that one password has been input is displayed on the display screen 1g of the wireless portable terminal 1 (FIG. 3D).

  Next, the base station 2 that has received the key press information transmits the key press information to the control unit 5 via the communication unit (step S7 in FIG. 4).

  Next, the control unit 5 that has received the key press information takes out the key arrangement to be displayed on the display screen 1d of the wireless portable terminal 1 when inputting the next password from the database unit 7 (step S8 in FIG. 4). At this time, it is also possible to change the combination of numbers and alphabets assigned to one key. For example, the key (“5 (CD)”) on the display screen 1 d can be changed to (“5 (PQ)”). However, this change is not always necessary.

  Next, the control unit 5 transmits the extracted key arrangement to the display screen 1d of the wireless portable terminal 1 via the communication unit 4 and the base station 2 (step S9 in FIG. 4).

  Next, the control unit 5 checks whether or not the key has been pressed a predetermined number of times. If the predetermined number of times has not been reached (in the case of “N” in step S10 in FIG. 4), steps S2 to S9 are repeated. .

  On the other hand, when the predetermined number of times is reached, that is, when the key is pressed by the number of digits of the code number (in the case of “Y” in step S10 in FIG. 4), the code is transmitted from the wireless portable terminal 1 to the base station 2. The number is transmitted (step S11 in FIG. 4).

  As described above, according to the best mode of the present invention, the key arrangement is changed every time a digit number is entered, and the key arrangement is not permanently displayed. It is possible to reduce the risk of leakage to a third party easily.

  In the above-mentioned best mode, key press information is transmitted to the base station 2 every time a password is entered, but before starting to input the first password, the key arrangement for the number of input digits is wirelessly carried in advance. It is also possible to transmit it to the terminal 1.

  According to the first embodiment, it is not necessary to perform communication between the wireless portable terminal 1 and the wireless portable terminal input support system 3 as many times as the number of key presses. This makes it possible to effectively use the line and reduce power consumption.

  In the above-described best mode, keys other than the password (other than the numeric key and the symbol key) such as a “decision” key and a “clear” key are randomly rearranged (see FIGS. 2A and 2B). ), Keys other than the password can be fixed positions.

  According to the second embodiment, operability can be improved.

  In the above-mentioned best mode, keys other than the code number (other than the numeric key and the symbol key) such as the “OK” key and “Clear” key are not displayed when the object or the like is not close to the sensor key 11. It is also possible to always display keys other than the password.

  According to the third embodiment, operability can be improved.

  FIG. 5 is a configuration diagram of the wireless portable terminal 1 of the fourth embodiment. In the above-mentioned best mode, the sensor keys 11 for displaying the key arrangement are provided at fixed positions. However, as shown in the figure, each key (for example, “5 (CD)” key) is provided with a sensor function. When an object approaches the key portion, it is possible to display a number assigned to the key.

  That is, first, an object is brought close to a predetermined key, and the number of the key is displayed. Next, when the displayed number matches the desired number, the key is further pressed. Thus, in this embodiment, the key operation has two stages.

  Here, it should be noted that the only displayed keys are the keys that bring the object closer, and the other keys remain hidden.

  According to the fourth embodiment, since only one key is displayed, it is possible to further reduce the risk that the entered password is easily leaked to a third party.

  The present invention can be used for providing information related to key arrangement on a wireless portable terminal and mounting a key arrangement screen on a moving object.
