JP 2004-086790 A

  In the conventional apparatus described in Patent Document 1, if a button adjacent to a desired button is erroneously operated first, even if the desired button is pressed immediately after that, the operation of the desired button is accepted by invalidation. There was a problem that it was not possible.

  The present invention has been made to solve the above-described problems, and an information input device capable of accurately preventing an erroneous operation by invalidating an operation of a key button from an operator's erroneous operation history, and The purpose is to obtain an information input method.

An information input device according to the present invention detects an input unit having a plurality of key buttons for information input, a storage unit storing a history of erroneous operation of the key buttons of the input unit, and operations on the key buttons of the input unit. In addition, if the detected operation of the key button is an erroneous operation, the detection unit that stores the history of erroneous operation of the key button in the storage unit, and the erroneous operation that stores the history in the storage unit exceeds a predetermined number of times, A controller that disables detection by the key button detection unit , and the detection unit has a predetermined time interval from when the key button of the input unit is operated until another key button of the input unit is continuously operated. Shorter than the value, the key button that was operated first is adjacent to another key button that was subsequently operated, and the processing by the operation of the first key button is canceled, and other key buttons When the operation is performed again, it is determined that the first key button is erroneously operated, and the operation history of the key button is stored in the storage unit as the erroneous operation history, and the control unit stores the history of the key button in the storage unit. When the number of erroneous operations exceeds a predetermined number, the detection by the detection unit of the key button is invalidated .

  According to the present invention, the erroneous operation of the key button is stored in the storage unit, and when the number of erroneous operations stored in the storage unit exceeds a predetermined number, the detection by the detection unit of the erroneously operated key button is detected. Since it is invalidated, there is an effect that an erroneous operation due to parallax between the operator's eyelids and the apparatus can be accurately prevented.

It is a block diagram which shows roughly the structure of the information input device by Embodiment 1 of this invention. It is a figure which shows the specific example of the input means of FIG. 4 is a flowchart illustrating a flow of operations performed by the information input device according to the first embodiment. It is a flowchart which shows the flow of operation | movement by the information input device of Embodiment 2 of this invention.

Embodiment 1 FIG.
FIG. 1 is a block diagram schematically showing a configuration of an information input apparatus according to Embodiment 1 of the present invention. In FIG. 1, an information input device 10 according to Embodiment 1 includes an image display unit (input unit) 11 and a hard key (input unit) 12 as input means, and includes a detection unit 13 and an information storage unit (storage unit). ) 14, a control unit 15 and a display control unit 16. The image display unit 11 is configured by a touch panel and displays a soft key button (hereinafter referred to as a touch key). The hard key 12 is arranged adjacent to the touch key displayed on the image display unit 11.

  The detection unit 13 is a component that detects an operation on the touch key or the hard key 12 displayed on the image display unit 11. The information storage unit 14 is a storage unit that stores a history of erroneous operations among the operations detected by the detection unit 13, and the control unit 15 is based on the erroneous operation history stored in the information storage unit 14. This is a component that invalidates the operation detection of the touch key and the hard key 12 by. The display processing unit 16 is a component that controls the display processing of the image display unit 11 and reflects the determination result by the control unit 15 on a touch key or the like.

FIG. 2 is a diagram showing a specific example of the input means of FIG. 1, and shows the image display unit 11 of the touch panel and the hard keys 12 arranged in the vicinity thereof. As the input means shown in FIG. 2, for example, an input device of an in-vehicle device such as a navigation device is assumed. In such an in-vehicle device input device, the touch key (input unit) 11a (group A) and the hard key 12 (group B) of the touch panel are in the vicinity as shown in FIG. In the example shown in FIG. 2, the keys of the A group and the B group are arranged in two stages as viewed from the operator side, and the arrangement of the key buttons is close due to space restrictions.
For this reason, for example, when trying to press the touch key 11a, the nearby hard key 12 is accidentally touched, and the key of the group B which is not intended by the operator may become effective. In order to avoid such an erroneous operation, in the present invention, a history of erroneous operations is taken, and if a predetermined condition defined according to the history is used as a determination criterion and the condition is satisfied, the operation is performed even if the key of the group B is pressed. Invalidate the next pressed key of group A.

Next, the operation will be described.
FIG. 3 is a flowchart showing a flow of operations performed by the information input device according to the first embodiment, and shows erroneous operation determination and key operation invalidation processing when information is input by key operations. Note that FIG. 1 is referred to for the configuration of the information input device 10.
First, when the operator operates the hard key 12 (step ST101), the detection unit 13 detects the operated hard key 12 and measures an elapsed time since the operation of the hard key 12.

  Thereafter, when the operator operates the touch key 11a (step ST102), the detection unit 13 detects the operated touch key 11a, and the touch key 11a is operated after the hard key 12 is operated in step ST101. Time interval is measured, and it is determined whether this time interval is shorter than a predetermined threshold (step ST103). Here, when the time interval is equal to or greater than the predetermined threshold (step ST103; NO), the detection unit 13 assumes that a desired key operation is in progress and returns to the process of step ST101.

  On the other hand, when the time interval is shorter than the predetermined threshold (step ST103; YES), the detection unit 13 operates the touch key 11a that was originally intended to be operated in step ST102 immediately after the hard key 12 is erroneously operated in step ST101. Assuming that this has been done, the process proceeds to step ST104. The predetermined threshold of the time interval is an upper limit value of the time interval that should be recognized as a continuous operation, and may be arbitrarily set by the operator.

  In step ST104, the detection unit 13 determines whether or not these keys are adjacent from the position of the hard key 12 detected in step ST101 and the position of the touch key 11a detected in step ST102. At this time, if the hard key 12 and the touch key 11a are not adjacent to each other (step ST104; NO), the detection unit 13 assumes that a desired key operation is in progress and performs the process of step ST101. Return to.

  When the hard key 12 and the touch key 11a are adjacent to each other (step ST104; YES), the detection unit 13 shifts to a waiting state for a cancel operation by the operator for a predetermined time (step ST105). If there is no cancel operation after waiting for the predetermined time (step ST105; NO), the detection unit 13 assumes that a desired key operation is in progress and returns to the process of step ST101.

  In addition, when there is a cancel operation from the operator within the predetermined time (step ST105; YES), the detection unit 13 originally wanted to operate because the touch key 11a and the hard key 12 are adjacent to each other. It is assumed that the hard key 12 is erroneously operated prior to the touch key 11a, and the operator has performed a cancel operation due to a transition to an unintended screen (a screen corresponding to the operation of the hard key 12).

  Thereafter, when the operator operates the same touch key 11a as in step ST102 (step ST106), the detection unit 13 regards that the operation of the touch key 11a originally intended to be operated by the operator is performed again, and includes a step including an erroneous operation. Information indicating a series of procedures from ST101 to step ST106 is stored in the information storage unit 14 as an erroneous operation history (step ST107).

  When the history of erroneous operations is taken by the detection unit 13, the control unit 15 searches the information storage unit 14 for the history of erroneous operations stored in step ST107 (information indicating the series of procedures including erroneous operations). It is determined whether or not the number of pieces of information indicating erroneous operations with the same series of procedures, that is, the number of erroneous operations exceeds a predetermined number (step ST108). Here, if the number of erroneous operations is less than or equal to the predetermined number (step ST108; NO), the control unit 15 determines that the current erroneous operation is a sudden one that does not depend on the operator's habit or the like, and the process of step ST101 is performed. Return to. The predetermined number of times may be set in the control unit 15 by the operator to an arbitrary value.

  On the other hand, if the number of erroneous operations exceeds the predetermined number (step ST108; NO), the control unit 15 regards that the erroneous operation of the current procedure has been repeatedly performed by the operator, and then in step ST101. Even if the hard key 12 is operated, the detection of the hard key 12 by the detection unit 13 is temporarily invalidated (step ST109). As a result, the detection of the touch key 11a operated in step ST102 becomes valid before the hard key 12.

As described above, according to the first embodiment, the history of erroneous operation of the hard key 12 is stored in the information storage unit 14, and the number of erroneous operations stored in the information storage unit 14 exceeds a predetermined number. Then, the detection by the detector 13 of the erroneously operated hard key 12 is invalidated.
By doing so, an erroneous operation that touches not the touch key 11a that the operator wants to operate but the adjacent hard key 12 that the operator does not intend due to the parallax of the button layout from the operator's eyelid or the operator. If it repeats, detection of the hard key 12 which touched first will be invalidated, and operation detection of the touch key 11a operated later will become effective first. Thereby, it is possible to make it appear that the operation intended by the operator is progressing, and it is possible to reduce the troublesomeness of the operation of the operator.

  Further, according to the first embodiment, the detection unit 13 continues to operate with the hard key 12 because the time interval from when the hard key 12 is operated to when the touch key 11a is continuously operated is shorter than a predetermined value. When the touch key 11a is adjacent to each other and the processing by the operation of the hard key 12 is canceled and the operation of the touch key 11a is performed again, it is determined that the hard key 12 is erroneously operated, and the hard key 12 is stored in the information storage unit 14 as an erroneous operation history, and the controller 15 detects the hard key 12 when the number of erroneous operations of the hard key 12 stored in the information storage unit 14 exceeds a predetermined number of times. The detection by the unit 13 is invalidated. By doing in this way, the misoperation which arises between the hard key 12 and the touch key 11a which were arrange | positioned closely can be detected correctly.

Embodiment 2. FIG.
The information input device according to the second embodiment is basically the same as the configuration shown in FIG. 1 in the first embodiment. However, when the number of erroneous operations is reduced, the key detection is temporarily disabled. It differs in the point which cancels. Therefore, refer to FIG. 1 for the configuration of the information input apparatus according to the second embodiment.

Next, the operation will be described.
FIG. 4 is a flowchart showing the flow of operations performed by the information input device according to the second embodiment of the present invention. The hard key 12 is temporarily detected by the erroneous operation determination described with reference to FIG. 3 in the first embodiment. Shows the case where it is disabled.
When the operator operates the touch key 11a (step ST201), the detection unit 13 detects the operated touch key 11a. The control unit 15 includes a hard key 12 that is temporarily disabled in the vicinity of the touch key 11a detected by the detection unit 13 (a hardware that is temporarily disabled adjacent to the touch key 11a. It is determined whether or not the key 12) exists (step ST202). If there is no hard key 12 that temporarily disables detection near the touch key 11a operated this time (step ST202; NO), the process returns to step ST201.

  When there is a hard key 12 whose detection is temporarily disabled near the touch key 11a operated this time (step ST202; YES), the detection unit 13 detects the operation of the hard key 12 within a predetermined time. Shifts to a waiting state to be executed (step ST203). When the operation of the hard key 12 is detected by the detection unit 13 within a predetermined time (step ST203; YES), the control unit 15 is the one in which the operator performs the erroneous operation determined in the first embodiment again. And return to the process of step ST201.

  On the other hand, if the operation of the hard key 12 whose detection is temporarily disabled is not detected (step ST203; NO), the detection unit 13 shifts to a waiting state for a cancel operation by the operator for a predetermined time ( Step ST204). When the cancel operation is detected within a predetermined time by the detection unit 13 (step ST204; YES), the control unit 15 regards that the operator has made an erroneous operation, and returns to the process of step ST201.

  Further, when the cancel operation is not detected by the operator within a predetermined time (step ST204; NO), the detection unit 13 detects the hard key 12 whose detection is temporarily disabled after the operation of the touch key 11a. Since neither the operation nor the cancel operation is performed, it is determined that there is no erroneous operation in the current operation by the operator, and information indicating a series of procedures from step ST201 to step ST204 is stored in the information storage unit 14 as a history of no erroneous operation. Store (step ST205).

  When the history of no erroneous operation is taken by the detecting unit 13, the control unit 15 searches the information storage unit 14 for the history of no erroneous operation stored in step ST205 (information indicating the above-described series of procedures without an erroneous operation). Thus, it is determined whether or not the number of pieces of information with the same series of procedures, that is, the number of times of no erroneous operation exceeds a predetermined number (step ST206). Here, if the number of times of no erroneous operation is equal to or less than the predetermined number (step ST206; NO), the control unit 15 returns to the process of step ST201. The predetermined number of times may be set in the control unit 15 by the operator to an arbitrary value.

  On the other hand, if the number of times of no erroneous operation exceeds the predetermined number (step ST206; NO), the control unit 15 temporarily disables the detection of the hard key 12 in step ST108 of FIG. 3 of the first embodiment. However, it is considered that the erroneous operation related to the hard key 12 is not repeatedly performed, and the temporary detection invalidation for the hard key 12 is canceled (step ST207). In this way, the control unit 15 performs control so that the operation is detected as the key operation is performed.

As described above, according to the second embodiment, the detection unit 13 stores in the information storage unit 14 a history of erroneous operation of the touch key 11a and the control unit 15 stores the information in the information storage unit 14. When the correct operation storing the history exceeds a predetermined number of times, if there is a hard key 12 in which detection by the detection unit 13 is invalid in the vicinity of the touch key 11a that has been correctly operated, the detection of the hard key 12 is detected. Cancel invalidity.
In the first embodiment, the detection of the hard key 12 that the operator accidentally touches first is invalidated. However, when the operator does not repeatedly perform the erroneous operation, the hard key 12 pressed first is If it is disabled, it will return and become unusable.
Therefore, by canceling the invalidation of the operation detection of the hard key 12 as described above and detecting the key as usual, the invalidation of the key operation detection is always performed in accordance with the habit of the operator's operation. Or it is possible to control the effectiveness.

  In the first embodiment and the second embodiment, a history is taken in step ST106 in FIG. 3 or step ST205 in FIG. 4, but the operator is identified before the operation, and the history is taken for each operator. It may be. For example, as the premise process of FIGS. 3 and 4, an operator identification process is performed, and a history is taken for each operator in step ST106 of FIG. 3 and step ST205 of FIG. By doing so, it is possible to invalidate the operation detection of the hard key 12 or cancel the operation detection according to the habit of each operator.

In the first embodiment and the second embodiment, the case where the touch key 11a (group A) and the hard key 12 (group B) are used has been described as an example, but (group A) (group B). May be replaced as follows.
(1) (Group A) is a hard key 12, and (Group B) is a touch key 11a adjacent thereto.
(2) (Group A) is a touch key 11a and (Group B) is a touch key 11a adjacent thereto.
(3) (Group A) is the hard key 12 and (Group B) is the adjacent hard key 12
