Description

  The present invention relates to an electronic device having a function of performing guidance on operation, a program suitable for the electronic device, and a guidance method.

  2. Description of the Related Art Conventionally, as a system having a man-machine interface such as a navigation system, a system that performs voice guidance for assisting operation when a complicated operation procedure is required is known. In addition, a system that allows the user to arbitrarily switch the output and non-output of voice guidance, and a system that switches the output and non-output of voice guidance according to the number of operations, operation speed, etc. are also disclosed. Yes.

  Specifically, for example, when an operation button is pressed for a predetermined time or more, a function assigned to the operation button is executed, and when the operation button is pressed for a predetermined time or less, the function is explained by voice. Thus, there is known a technique that enables even a visually impaired person to easily perform an operation (see, for example, Patent Document 1). In addition, there is a known technology that enables voice guidance on basic matters when using the device and voice guidance on individual countermeasures that are necessary as needed during actual use, depending on the prescribed operation. (For example, refer to Patent Document 2). Furthermore, the degree of familiarity with the operation is determined based on the number of accesses by the user, the number of guidance to the user, the number of talkback repetitions in speech recognition, the utterance speed, etc. A technique for changing the speed, pitch, and the like is also known (see, for example, Patent Document 3).

  The main guidance methods in these prior arts are classified as follows. That is, (1) whether to output voice guidance, whether to switch the contents of the guidance to detailed or simple, etc. by using a selection button, (2) functions that are subject to voice guidance The buttons for performing voice guidance are switched with respect to the output of voice guidance according to the pressed time. (3) The degree of familiarity with the operation subject to voice guidance is determined by the number of operations, etc. Switching for voice guidance output depending on the degree, (4) Switching for voice guidance output depending on the operation speed of the operation targeted for voice guidance, etc. is there.

  However, in the conventional methods (3) and (4) that automatically switch the voice guidance output, the degree of operation familiarity is determined based on the operation speed, the number of operations, etc. Therefore, it may be difficult to say that the determined degree of familiarity necessarily indicates the familiarity of the operator in an essential sense. In addition, in the case of the method in which the operator selects and switches the output and non-output of the voice guidance of (1) and (2), the selection act itself is troublesome and the output conditions of the voice guidance are classified in detail. Often difficult to do.

  An object of the present invention is to make it possible to output guidance related to operation at a more accurate timing in an electronic device in view of the problems of the conventional technology.

  In order to achieve the above object, an electronic device according to a first invention includes an operation error detection unit that detects occurrence of a predetermined operation error, a count unit that counts the number of occurrences of an operation error, and a count of the number of operation error occurrences. Guidance output means for outputting a predetermined guidance when the value reaches a predetermined value of 2 or more is provided.

  Here, examples of the electronic device include a navigation device and an audio / visual device. As an operation mistake, for example, when a predetermined button in an invalid state is pressed, or when an input character to be confirmed is not confirmed and a transition to another state is performed, an operation to turn off the power This corresponds to the case where a predetermined process is interrupted. Guidance includes, for example, voice, text display, indicator using LED, and beep sound.

  In this configuration, when the occurrence of a predetermined operation error is detected by the operation error detection means, the count means counts up the count value of the number of operation error occurrences. Then, when the count value reaches a predetermined value, the guidance output means performs a predetermined guidance. Therefore, by appropriately determining the predetermined value as a criterion for determining whether or not to perform guidance, it is possible to objectively determine the degree of familiarity with an operation related to a predetermined operation error and perform guidance at an appropriate timing. it can.

  In the electronic device according to a second aspect of the present invention, in the first aspect, the operation error detecting means has a processing capability when a predetermined operation member in an invalid state is operated, or when a prohibited predetermined operation is performed. When a predetermined operation exceeding is performed, the received input is not confirmed in the predetermined input acceptance state, and when the state is changed from the state to another state by another operation, in the predetermined input acceptance state, If the input is not confirmed and the state transitions to another state after a predetermined time has elapsed, or when a predetermined setting operation is being performed, the power is turned on before the setting is completed. A case where the signal is turned off is detected as the predetermined operation error.

  An electronic device according to a third invention is characterized in that, in the first or second invention, the counting means clears the count value of the number of occurrences of operation mistakes every time the guidance is performed a predetermined number of times. As the predetermined number of times, an arbitrary number of one or more times can be adopted.

  An electronic device according to a fourth invention is characterized in that, in any one of the first to third inventions, the electronic device has means for changing the content of the guidance according to the number of times the guidance is performed.

  An electronic device according to a fifth invention is the electronic device according to any one of the first to fourth inventions, wherein the predetermined operation acceptance state in which the predetermined operation error can occur is completed without detecting the occurrence of the predetermined operation error. Accordingly, there is provided a means for reducing the count value of the number of operation error occurrences. Here, as a predetermined operation acceptance state, for example, a state in which an operation screen for accepting an operation for setting sound effects is displayed, a state in which an operation screen for accepting input of characters is displayed, and an operation This corresponds to a state in which operations through the screen are not accepted.

  The electronic device according to a sixth aspect of the invention is the electronic device according to any one of the first to fifth aspects, wherein the guidance output means is a point in time when an operation error that causes the count value of the number of operation error occurrences to reach a predetermined value occurs, or Thereafter, the guidance is output at the time when the operation is shifted again to the predetermined operation acceptance state where the operation error has occurred.

  According to a seventh aspect of the present invention, in the electronic device according to the first or second aspect, the counting means sets the initial value when the count of the number of occurrences of operation mistakes shifts to a predetermined operation acceptance state where the predetermined operation mistakes may occur. Starting from zero and continuing until the state ends.

  A program according to an eighth invention causes a computer to function as each means constituting the electronic device according to the first to seventh inventions.

  A guidance method according to a ninth invention includes an operation error detection step in which the electronic device detects the occurrence of a predetermined operation error, a counting step in which the electronic device counts the number of occurrences of the operation error, and an operation in which the electronic device operates A guidance output step of outputting a predetermined guidance in response to the count value of the number of miss occurrences reaching a predetermined value.

  According to the present invention, since guidance is performed according to the count value of the number of operation errors, it is possible to objectively grasp the familiar state of operation and perform guidance at an appropriate timing. In addition, since the content of the guidance is changed according to the number of times the guidance is performed, when the operation error is not lost, the guidance with higher operation error suppression power can be performed.

The audio device 40 includes a speaker 41 that converts an audio signal into sound, and an audio output unit 42 that drives the speaker 41 based on a signal from the guidance control unit 11.

  The guidance control unit 11 determines whether or not guidance is necessary based on the number of operation mistakes stored in the operation mistake number storage unit 21 and the power supply information from the navigation control unit 12 or information input by the operation unit 31. judge. Based on the determination result, the guidance control unit 11 controls the display output unit 34 and performs display as guidance by the display unit 32 and the LED 33. Alternatively, necessary voice data is read from the voice database 22 and supplied to the voice output unit 42 to perform voice guidance.

  FIG. 2 is a front view of the system of FIG. 1 and shows an operation panel. The hard key 31b includes various keys for opening / closing the operation panel, turning the power on / off, various operations related to navigation, various operations related to display and audio, and the like. The touch panel 31a is provided on the display unit 32, and the main body control unit 10 recognizes the pressed button or key based on the touch position on the touch panel 31a and the display position of the button or key on the display unit 32. It can be done. The LED 33 has a function as an indicator for displaying various information.

  FIG. 3 shows a portion having an insertion slot such as a DVD or a memory stick, which appears when the operation panel of FIG. 2 is opened. Reference numeral 35 in the figure denotes a built-in hard disk constituting the data store unit 20. Note that the operation error count storage unit 21 may be constituted by a built-in memory without using the hard disk 20. FIG. 4 is a rear view of the system of FIG. In the figure, reference numeral 43 denotes a power connector, which constitutes a power line and an audio output line.

  FIG. 5 shows an example of a display screen on the display unit 32. In the figure, reference numeral 51 denotes five selection buttons displayed for the user to select a predetermined function, and 52 and 53 are related to a predetermined button 54 of the selection buttons 51, respectively. Two and one related button that are valid only when pressed. Reference numeral 55 denotes a screen end button for ending the screen of FIG. 5 and shifting to another screen. When one of the five selection buttons 51 other than the predetermined button 54 is pressed, the related buttons 52 and 53 are invalidated, and the display design is changed to a display design indicating that the button cannot be pressed. It has become.

  FIG. 6 is a flowchart showing a part of processing by the main body control unit 10. In the process of FIG. 5, each time the invalidated related buttons 52 and 53 are pressed while the screen display of FIG. 5 is being performed, the number of times of pressing is counted as an operation error, and a predetermined count value is obtained. When it reaches, predetermined guidance is given. At the start of processing, the count value is zero.

  That is, the processing of FIG. 6 is started, and when the pressing of any button is detected in step 61, the main body control unit 10 determines whether or not the pressed button is the screen end button 55 in step 62. To do. If it is determined that it is not the screen end button 55, the process proceeds to step 63 to determine whether or not the pressed button is the predetermined button 54. If it is determined that the button is the predetermined button 54, the display design of the related buttons 52 and 53 related to the predetermined button 54 is changed to a display design indicating that the button can be pressed in step 64, and the related button 52 is displayed. And 53 are activated. Thereafter, the process returns to step 61.

  If it is determined in step 63 that the pressed button is not the predetermined button 54, the process proceeds to step 65 to determine whether the pressed button is the related button 52 or 53. If it is determined that the button is not a related button, the pressed button can be regarded as a button other than the predetermined button 54 of the selection buttons 51. Accordingly, in this case, the process proceeds to step 66, where the display design of the related buttons 52 and 53 is changed to a display design indicating that the button cannot be pressed, and the related buttons 52 and 53 are invalidated. Thereafter, in step 67, processing corresponding to the pressed selection button 51 is performed, and the process returns to step 61.

  If it is determined in step 65 that the pressed button is the related button 52 or 53, the process proceeds to step 68, and it is determined whether or not the related buttons 52 and 53 are valid. “Valid” means that the related buttons 52 and 53 are activated in step 64 by pressing the predetermined button 54. Therefore, if it is determined that the button is valid, in step 69, processing corresponding to the pressed related button 52 or 53 is performed, and the process returns to step 61.

  If it is determined in step 68 that the related buttons 52 and 53, which are the pressed buttons, are not valid, the button press is an operation error, so the process proceeds to step 70 and the count value of the number of operation errors is counted up. To do. Next, in step 71, it is determined whether or not the operation error count value has reached a predetermined value. If it is determined that the predetermined value has not been reached, the process returns to step 61.

  If it is determined in step 71 that the operation error count value has reached a predetermined value, the process proceeds to step 72 to perform predetermined guidance. That is, sound indicating the operation method on the screen of FIG. The content of the guidance is, for example, “XXX button (buttons 52 and 53) is for setting △△△. This setting becomes effective when the XXX button (button 54) is pressed. Is applicable. Thereafter, the process returns to step 61.

  If it is determined in step 62 that the pressed button is the screen end button 55, the process proceeds to step 73, and the count value of the number of operation errors is cleared. Thereby, the process of FIG. 6 is completed.

  According to the process of FIG. 6, when the number of operation mistakes for pressing the invalidated related button 52 or 53 reaches a predetermined value, the guidance for leading to the correct operation is performed. Therefore, the guidance is performed at an appropriate timing. It is possible to prevent the user from repeating operation mistakes.

  FIG. 7 shows another example of the display screen on the display unit 32. 75 is a character input key for designating an input character or symbol, 76 is an input auxiliary key for deleting the input character or inputting a space, 77 is an area for displaying the input character or symbol, 78 is A confirmation key for confirming the input of the input character or symbol, and 79 is a screen end key for ending the screen of FIG.

  FIG. 8 is a flowchart showing another process performed by the main body control unit 10. In this process, when the screen end key 79 is pressed without confirming the input result after inputting characters or the like on the display screen of FIG. When 75 or 76 is hit repeatedly, the number of times of pressing due to repeated hits does not match the number of confirmed characters due to processing speed limitations, the operation count is counted as an operation error, and the predetermined count value is reached. At this time, the predetermined guidance is performed when the character input acceptance state on the screen of FIG.

  That is, when the process is started, the main body control unit 10 first determines in step 81 whether or not the count value of the number of operation mistakes has reached a predetermined value. If it is determined that the predetermined value has been reached, the routine proceeds to step 82 where predetermined guidance is performed. That is, sound indicating the operation method on the screen of FIG. As the content of the guidance, for example, “If the entered character is to be confirmed, press the OK key (confirmation key 78) before ending. Also, please perform the operation slowly”. Thereafter, in step 83, the operation error count value is cleared, and the process proceeds to step 84. On the other hand, if it is determined in step 81 that the operation error count value has not reached the predetermined value, the process immediately proceeds to step 84.

  Step 84 waits for any key to be pressed. When the key press is detected, the process proceeds to step 85, and it is determined whether or not the pressed key is a key for inputting characters or the like, that is, whether or not it is the character input key 75 or the input auxiliary key 76. If it is determined that the key is an input key, in step 86, input processing corresponding to the pressed key is performed, the display in the display area 77 is updated as necessary, and the process returns to step 84.

  If it is determined in step 85 that the pressed key is not an input key, the process proceeds to step 87 to determine whether or not the pressed key is the confirmation key 78. If it is determined that the key is the confirmation key 78, the process proceeds to step 88, and the number of times the input key 75 or 76 is pressed, that is, the number of characters or symbols entered is compared with the number of characters or symbols confirmed. Then, it is determined whether or not the numbers of both characters match. If it is determined that they match, the process returns to step 84 as it is. If it is determined that they do not coincide with each other, it is regarded as an operation error due to repeated hitting of the key 75 or 76, and in step 89, the count value of the number of operation errors is counted up, and the process returns to step 84.

  If it is determined in step 87 that the pressed key is not the confirmation key 78, the process proceeds to step 90 to determine whether or not the screen of FIG. 7 is to be ended, that is, the pressed key is the screen end key 79 or the hard key 31b ( It is determined whether the power-off key in FIG. If it is determined that the screen is not finished, the process returns to step 84. If it is determined that the screen is finished, the process proceeds to step 91, where it is determined whether or not the input character or symbol is confirmed by pressing the confirmation key 78.

  If it is determined in step 91 that the input character or symbol is not confirmed, it is regarded as an operation error. In step 92, the count value of the number of operation errors is counted up, and then the processing of FIG. To do. If it is determined that it has been confirmed, the processing of FIG.

  According to the processing of FIG. 8, when the screen of FIG. 7 is terminated without confirming the input characters and symbols, or when the power is turned off, the number of presses does not match the number of input characters due to repeated hits. In such a case, the number of operations is counted as an operation error, and when the count value reaches a predetermined value, guidance is performed so that the operation error does not occur. It is possible to prevent operation mistakes from being repeated.

  FIG. 9 shows another example of the display screen in the display unit 32. This screen is displayed while deleting certain data. In the display area 91 in the figure, a message is displayed indicating that operation input is prohibited because the data is currently being deleted, and that the power must not be turned off.

  FIG. 10 is a flowchart showing still another process by the main body control unit 10. In this process, when an operation to turn off the power or other operation input is performed in the state where the screen of FIG. 9 is displayed, this is regarded as an operation error, and the number of the error operations is counted. When the value reaches a predetermined value, the predetermined guidance is performed when the screen is shifted to the state where the screen of FIG. 9 is displayed again.

  That is, when the processing of FIG. 10 is started, the control unit 10 first determines in step 91 whether or not the count value of the number of operation mistakes has reached a predetermined value. If it is determined that the predetermined value has not been reached, the routine proceeds to step 97. If it is determined that the predetermined value has been reached, the routine proceeds to step 92, where it is determined whether or not the count value of the number of times guidance has been performed has reached a predetermined value. If it is determined that the predetermined value has not been reached, predetermined guidance for preventing an operation error is performed in step 93. The content of the guidance corresponds to, for example, “Currently deleting data. Do not perform other operations. Do not turn off the power”. Thereafter, in step 95, the count value of the number of times of guidance is counted up, and the process proceeds to step 96.

When it is determined in step 92 that the count value of the number of times guidance has been performed has reached a predetermined value, in step 94, guidance having a stronger deterrence power for operation mistakes than the guidance in step 93 is output. The content of the guidance corresponds to, for example, “If you perform other operations or turn off the power while deleting data, the data may be damaged . Thereafter, the process proceeds to step 96.

  In step 96, the count value of the number of operation mistakes is cleared. In the next step 97, it is determined whether or not any operation, for example, pressing of a key or button or an operation of turning off the power has been performed. If such an operation has not been performed, the process proceeds to step 99 as it is. If it is determined that the operation has been performed, since such an operation is an operation error, in step 98, the count value of the number of operation errors is set. After counting up, the routine proceeds to step 99.

  In step 99, it is determined whether or not the screen of FIG. When the screen is terminated, there are a case where the data deletion process is completed and the screen is shifted to another display state, or a case where the power is turned off and the screen is forcibly terminated. When it is determined that the screen is not finished, the process returns to step 97, and when it is judged that the screen is finished, the process of FIG. 10 is finished.

  According to the process of FIG. 10, since the number of times of guidance is counted and the count value reaches a predetermined value, guidance with stronger deterrence against operation mistakes is performed than before, so it is possible to deal with more dangerous operation mistakes. It is possible to provide guidance with a high operation error prevention effect at an appropriate timing.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above description, the state in which the screens of FIGS. 5, 7, and 9 are displayed as a state in which a predetermined operation is accepted is exemplified, and the process of counting the number of operation mistakes and performing guidance for each is separately performed. As described above, these processes may be performed concurrently in one system. In other words, every time the screen transitions to each screen in FIGS. 5, 7, and 9 in one system, it is possible to separately count mistake operations that have occurred on each screen and to provide guidance for each screen. .

  Further, in the above description, as an operation error, when an invalid operation element is operated, when an operation exceeding the processing capability is performed, an accepted input is confirmed in a state where a predetermined input is accepted. However, in addition to these cases, for example, in a state where a predetermined input is accepted, a transition from the state to another state by another operation and a case where a prohibited operation is performed have been described. When the input is not confirmed and the state transitions from the state to another state after a predetermined time has elapsed, or when a predetermined setting operation is being performed, the power is turned off before the setting is completed. An operation error can also be made when it is turned off. It should be noted that, in a predetermined operation acceptance state, which of these operation mistakes is counted and the guidance target can be selected as the most appropriate one in that state. Guidance may be performed by integrating the count results of a plurality of operation errors.

  In the above description, no particular reference was made to the predetermined count value of the number of operation mistakes to which guidance should be given. Two or more arbitrary values can be set according to the importance level.

  Although not mentioned above, for example, in the process of FIG. 8, when the process of FIG. 8 is terminated without detecting the occurrence of an operation error, the count value of the number of occurrences of operation mistakes is decreased. May be.
