Description

  The present invention relates to an input device and an input method.

  2. Description of the Related Art In recent years, an electronic device in which an operation of pressing a button, an operation of switching a switch, or the like is performed by a touch operation superimposed on a display or a touch operation on a touch pad has been widely used (for example, Patent Document 1). In such electronic devices, there are fewer mechanical moving parts such as buttons and switches, which can reduce the failure rate and reduce the unevenness of the appearance, as well as technical advantages such as easy waterproofing. It has the aesthetic advantage of making an advanced impression.

  In an input device using a touch panel or a touch pad (hereinafter also referred to as a touch-type input device), not only a user touches an operation target such as a button but also an operation when touched (touch operation). Differences such as touching for a short time (also referred to as tap or click), touching for a short time (double click), touching for a predetermined time (long press), etc. The function can be executed. For this reason, the touch type input device does not execute the function when the user touches the operation target, but detects the touch operation when the user leaves the operation target after touching the operation target. Many perform functions according to touch operations.

JP 2014-167600 A

  In the case of an input device that executes a function when the user leaves the operation target, there is a slight gap between the user touching the operation target and the execution of the function, and an error may be noticed during this time. In this case, since it has been determined that the function corresponding to the wrong operation target has been selected even before the execution of the function, an undesired function is executed when the finger is released. That is, there is a problem that even if an error is noticed, the wrong input operation cannot be canceled.

  Therefore, an object of the present invention is to provide a technique that enables a user to cancel an operation based on the contact after the user touches the operation surface when performing an input by touching the operation surface.

In order to solve the above-described problems, the input device of the present invention

After the first contact is detected by the detection unit, when the first contact is canceled, an operation input unit that inputs an operation corresponding to the first contact;
After the first contact is detected, before the first contact is canceled, when the second contact is detected, a canceling unit for canceling that the first contact is detected,
Is provided.

ADVANTAGE OF THE INVENTION According to this invention, when touching an operation surface and performing an input, after a user contacts an operation surface, the technique which enables cancellation of operation based on this contact can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

<Device configuration>
FIG. 1 is a block diagram illustrating a configuration of a system including an input device according to the present embodiment, FIG. 2 is a front view of the input device, and FIG. 3 is a cross-sectional view of a panel unit.

  The system 100 includes a panel unit 10, a control unit 20, and a function unit 30. The panel unit 10 and the control unit 20 constitute an input device 12 for inputting operation information by the user to the function unit 30. The panel unit 10 includes an operation panel 11 that receives an operation by an operation part such as a user's finger, a touch panel (detection unit) 14 that detects an operation on an operation area on the operation panel, and a portion near the center of the operation panel 11. And a display 15 arranged. That is, the touch panel 14 is provided around the display 15. Note that the touch panel 14 is not limited to the periphery of the display 15, and may be disposed so as to be superimposed on the entire surface of the operation panel 11, and may be superimposed on the display 15 near the center. Moreover, although the panel unit 10 of the present example is configured to include the display 15, the display 15 is not an essential configuration, and the display 15 may be omitted. For example, the display 15 and the panel unit 10 may be configured separately, and the panel unit 10 may be configured as a so-called touch pad, which includes the operation panel 11 and the touch panel 14. In the present embodiment, the user's operation part is a part that performs an operation by touching the operation surface, and is typically a finger. Hereinafter, the operation site is also simply referred to as a finger, but is not limited to the finger, and may be a site other than the finger, such as a palm or an elbow. Further, the operation part may be something other than the user's body, such as a gloved finger or a touch pen, as long as the detection unit can detect contact with the operation surface.

  The operation panel 11 of this example is a transparent substantially flat plate-like member, and has a surface arranged on the user side as an operation surface 101 and receives an operation (hereinafter also referred to as a touch operation) by touching an operation part. Further, at least a part of the operation surface 101 is defined as an operation target for executing a specific function such as the slide operation units 110, 120, and 130 and the touch operation units 191 to 196. The touch operation units 191 to 196 are operation targets simulating buttons to which functions such as sound source selection and channel change are assigned, and the slide operation units 110 and 120 are assigned functions such as volume adjustment and channel selection. The linear operation target and slide operation unit 130 is a dial-type operation target that adjusts an operation amount by sliding a finger in a circle.

The region where the operation target is set is subjected to printing and uneven processing so that the user can recognize each operation target. For example, in the slide operation units 110, 120, and 130, the range and direction in which the slide operation is possible are shown, and in the touch operation units 191 to 196, the range in which the touch operation is possible and the function when the touch operation is performed. The name etc. are shown.

  The touch panel 14 is a capacitive touch panel that obtains a contact position based on a change in capacitance when a user's finger contacts the operation surface. For example, in FIG. 2, a coordinate system having two axes (X axis and Y axis) orthogonal to each other in the operation surface (plane) is defined, and the contact position is obtained as coordinates in this coordinate system (hereinafter also referred to as position information). . The touch panel 14 is not limited to the capacitive method, but may be a resistive film method, an ultrasonic surface acoustic wave method, or an optical method.

  The display 15 is a display unit such as an LCD (Liquid Crystal Display), and receives a video signal such as a result of inputting a control signal corresponding to an operation detected by the touch panel 14 to the function unit 30 and displays it. .

  The control unit 20 detects a touch operation by the user based on a detection result (position information) by the touch panel 14, generates a control signal corresponding to the touch operation, and inputs the control signal to the function unit 30.

  The control unit 20 is a microcomputer provided with, for example, a CPU and a memory. The memory may include a main storage device and an auxiliary storage device. The main storage device is used as a work area for the CPU, a storage area for programs and data, and a buffer area for communication data. The main storage device is formed by, for example, a random access memory (RAM) or a combination of a RAM and a read only memory (ROM). Programs such as an operating system and firmware are installed in the memory.

The CPU is also called an MPU (Micro Processor Unit), a microprocessor, a processor, or a processing device. The CPU is not limited to a single processor, and may have a multiprocessor configuration. A single CPU connected by a single socket may have a multi-core configuration. At least a part of the processing of each unit may be performed by a processor other than the CPU, for example, a dedicated processor such as a digital signal processor (DSP), a graphics processing unit (GPU), a numerical operation processor, a vector processor, or an image processing processor. good. Further, at least a part of the processing of each unit may be an integrated circuit (IC) or other digital circuit. In addition, an analog circuit may be included in at least a part of each of the above parts. The integrated circuit includes an LSI, an application specific integrated circuit (ASIC), and a programmable logic device (PLD). The PLD includes, for example, a field-programmable gate array (FPGA). Each of the above units may be a combination of a processor and an integrated circuit. The combination is called, for example, an MCU (Micro Controller Unit), an SoC (System-on-a-chip), a system LSI, or a chip set.

  The CPU performs the functions of the operation input unit 201 and the cancellation unit 202 by loading the program stored in the memory into the main storage device and executing the processing described in the program.

  The operation input unit 201 inputs an operation corresponding to the first contact when the first contact is detected after the first touch is detected by the touch panel 14. For example, when the user touches the operation surface 101 with a finger and releases the finger from the operation surface 101, an operation is input.

  The cancellation unit 202 cancels that the first contact is detected when the second contact is detected before the first contact is canceled after the first contact is detected. The cancel unit 202 recognizes that the cancel operation has been performed when the first contact and the second contact have a predetermined displacement, and cancels the detection of the first contact. The displacement of the first contact and the second contact is a detection by the touch panel 14 about the first contact and the second contact, such as a change from a contacted state to a non-contacted state or a change in contact position. It is a change in results.

  For example, when the user touches the operation target on the operation surface 101 with a finger (first contact) and notices that the operation target is wrong, the other finger touches the operation surface 101 before releasing the first finger. Touch (second contact) When a predetermined operation is performed with these two fingers, it is determined that the first finger has not been touched and the function of the operation target touched by mistake is not executed. be able to. The canceling unit 202 is not limited to the first contact and the second contact, but can cancel that the first contact has been detected when the second contact has a predetermined displacement. Good.

  The function unit 30 is a device that executes control of a control target in accordance with a control signal input from the input device 12, and is, for example, an audio function that reproduces music or radio. In addition to the audio function, the system 100 of the present example is a functional unit that executes a navigation function such as calculation of a route to a destination and display of the route, and a visual function that reproduces a moving image and displays a television broadcast. The electronic device (AVN machine) 30 may be integrated. The function unit 30 is not limited to this, and may perform functions such as an air conditioner, a drive recorder, an angle adjustment of the side mirror, and an adjustment of the irradiation position (height) of the headlamp.

<input method>
Next, an input method in which the input device 12 inputs a control signal based on the detected touch operation to the function unit will be described. FIG. 4 is an explanatory diagram of an input method executed by the input device 12. The input device 12 starts the process of FIG. 4 when receiving an instruction to start the process or when the electric system of the vehicle is turned on.

  First, the input device 12 determines whether or not the first contact with the operation surface 101 has been detected (step S10). If the determination is negative (step S10, No), the processing in FIG. 4 ends.

  On the other hand, when an affirmative determination is made in step S10 (step S10, Yes), the input device 12 acquires the position information of the contact position and stores it in the memory (step S20).

  Next, the input device 12 determines whether the second contact is detected (step S30). For example, it is determined that there is a second contact when there is contact at a different location from the first contact, that is, when there are multiple contacts with respect to the operation surface 101.

  If it is negative determination in step S30 (step S30, No), the input device 12 will determine whether the 1st contact was eliminated (step S40). If it is negative determination here (step S40, No), the input device 12 will complete | finish the process of FIG. In the present embodiment, the first contact is eliminated means that the touch operation related to the first contact is completed. The determination that the first contact has been eliminated may be an affirmative determination not only when the contact portion has moved away from the operation surface 101 but also when the detection result by the touch panel 14 satisfies a predetermined condition. For example, when a double click or a single click is performed as the touch operation, the first contact is detected when a predetermined time (for example, 0.5 seconds) has elapsed since the first contact is detected after the first contact is detected. It is determined that the contact has been eliminated. That is, when the next contact is made within a predetermined time even if the operation part is moved away from the operation surface 101 for a moment, such as a double click, a series of operations including the second contact is detected as the first contact. To do. Not limited to this, a double click is performed when the first contact is detected and then the next contact is detected within a predetermined time (eg, 0.3 seconds) after the contact is no longer detected. As such, this second contact may be included in the first contact. Furthermore, after the first contact is detected, contact is continued for a predetermined time or longer, and when the contact is no longer detected (when pressed for a long time), there is no possibility of double-clicking. It may be determined that the first contact has been canceled immediately after no longer being detected.

  If an affirmative determination is made in step S40, the input device 12 specifies the operation target on which the first contact has been made based on the position information acquired in step S20, and sends a control signal indicating the corresponding operation to the function unit 30. In response to this, an input is made (step S50). For example, when the operation target specified based on the position information is any one of the touch operation units 191 to 196 shown in FIG. 2, an operation corresponding to the specified touch operation units 191 to 196 has been performed. The control signal shown is input to the function unit 30, and the functions assigned to the touch operation units 191 to 196 are executed. Further, when the operation target on which the first contact has been made is the slide operation unit 110, 120, 130, the control indicating the operation direction (slide direction) and the operation amount (slide amount) together with the corresponding operation. A signal is input to the functional unit 30. After the input in step S50, the input device 12 initializes the data stored in the memory in step S20 (step S60), returns to the state where the first contact is not detected, and ends the process of FIG.

  On the other hand, when it determines with having detected the 2nd contact in step S30 (step S30, Yes), the input device 12 acquires the positional information on the said contact position, and memorize | stores it in memory (step S70). Further, the input device 12 determines whether or not a predetermined cancel operation has been performed for the first contact and the second contact detected by the touch panel 14 (step S80). Details of the cancellation operation will be described later.

  If the negative determination is made in step S80 (step S80, No), the input device 12 terminates the processing of FIG. 4, and if the determination is affirmative (step S80, Yes), the data stored in the memory in step S20 is initialized. (Step S90), canceling that the first contact has been made, and ending the process of FIG. The process of FIG. 4 is repeatedly executed at a predetermined cycle until an instruction to stop the input device 12 is received or until the electric system of the vehicle is turned off.

  Thus, for example, when the user touches the operation target on the operation surface 101 with a finger (first contact), if the user notices that the operation target to be touched is incorrect, the user touches the operation surface 101 with another finger ( By performing a canceling operation such as (second contact) or long pressing, it can be said that there was no touch (first contact) on the wrong operation target.

  In FIG. 4, when the first contact is detected (step S10, Yes), the process of FIG. 4 is repeatedly executed until the first contact is eliminated, and the position information of the contact position is repeatedly acquired in step S20. Then, the operation trajectory is obtained by the change of the position information. For example, in the case of an operation on the slide operation units 110, 120, and 130, the direction and amount of the operation locus are input to the function unit 30 as the slide direction and slide amount of the control signal. If the second contact is detected (Yes in step S30), the position information of the contact position is repeatedly acquired in step S60 until it is determined that the canceling operation has been performed. ) To determine whether or not a cancel operation has been performed.

  FIG. 5 is a diagram illustrating an example of a cancel operation. FIG. 5A shows an example in which the finger 71 that made the first contact and the finger 72 that made the second contact are both moved downward as the cancel operation. In addition, the arrow in a figure has shown the operation locus | trajectory of a 1st contact and a 2nd contact. In other words, if both the position information acquired in step S20 and the operation locus based on the position information acquired in step S60 have moved downward, the input device 12 determines that a cancel operation has been performed (step S70, Yes). In FIG. 5A, it is determined that the cancel operation has been performed when the first contact and the second contact move downward, but this movement direction (operation direction) is limited to the downward direction. It may be a predetermined direction such as an upward direction or an outer direction of the operation panel 11.

FIG. 5B shows a finger 71 that has made a first contact and a finger 7 that has made a second contact as a cancel operation.
2 shows an example of flicking together. That is, when the position information acquired in step S20 and the operation trajectory based on the position information acquired in step S60 are both moved away from the operation surface 101, the input device 12 determines that the cancel operation has been performed. Determination is made (step S70, Yes). The input device 12 may determine that the cancel operation has been performed when flicked in a predetermined direction, or determines that the cancel operation has been performed in any direction without setting the flick direction. May be. Further, when the flick speed exceeds a threshold value, that is, when the flick is performed at a high speed, it may be determined that the cancel operation has been performed.

  FIG. 5C shows an example in which the finger 71 having made the first contact and the finger 72 having made the second contact are both moved so as to draw a check point as the canceling operation. That is, after both the position information acquired in step S20 and the operation locus based on the position information acquired in step S60 have moved, the direction is changed to move away from the operation surface 101, and the operation locus at this time is a letter shape. If it is, the input device 12 determines that a cancel operation has been performed (step S70, Yes).

  FIG. 5D shows an example in which the finger 71 that has made the first contact and the finger 72 that has made the second contact are both moved in a circle as a cancel operation. That is, when the position information acquired in step S20 and the operation trajectory based on the position information acquired in step S60 are both curved and moved, and return to substantially the same position and away from the operation surface 101, the input device 12 determines that a cancel operation has been performed (step S70, Yes). Note that the operation trajectory in this case may not be strictly circular.

  5A to 5D show an example in which the finger 71 that made the first contact and the finger 72 that made the second contact are moved together. When an operation such as moving in a predetermined direction, flicking, drawing a dot, or drawing a circle is performed with only the finger 72 that has made the second contact without moving the finger 71 that has made the first contact Alternatively, it may be configured to determine that a cancel operation has been performed.

  FIG. 5E shows an example in which double-clicking is performed with the finger 72 that has made the second contact as the canceling operation. That is, when the operation trajectory based on the position information acquired in step S60 is a distance from the operation surface 101 after short contact without moving more than a predetermined distance, the input device 12 performs a cancel operation. (Step S70, Yes). In this case, the canceling operation does not move the finger 71 that made the first contact, and double-clicks only with the finger 72 that made the second contact. You may click.

  FIG. 5F shows an example in which a specific area (cancellation area) is touched with the finger 72 that has made the second contact as the cancellation operation. That is, when the position information acquired in step S60 is within the cancel area, the input device 12 determines that a cancel operation has been performed (step S70, Yes). Here, the cancellation area is an area set in advance for canceling the first contact, and is, for example, the four corners or edges of the operation panel 11 (operation surface 101). In the example of FIG. In this example, the finger 71 touches the touch operation unit 196 and the finger 72 touches the edge of the operation panel 11. The cancel area may be an area indicating a cancel button or the like arranged in the operation surface 101 to be operated.

  Thus, it is not necessary to perform a specific movement operation such as flicking or double-clicking after performing the second contact, and the first contact can be easily canceled simply by performing the second contact in the cancellation area. . In addition, by defining areas that are easy for the user to touch, such as the four corners and edges of the operation panel 11, for example, the user who is driving can cancel the first contact without gazing at the operation panel 11.

  FIG. 5G shows an example in which the second contact is made by moving the finger 71 that has made the first contact to a specific region (cancellation region) without releasing it from the operation surface 101 as the cancel operation. Yes. In the example of FIGS. 5A to 5F, the second contact is that the finger 72 different from the first contact is touched with a finger 72 different from the first contact. However, not limited to this, in FIG. 5G, the finger 71 that has made the first contact is moved to make the second contact. For example, after detecting the first contact (step S10, Yes), the input device 12 repeats the process in FIG. 4 in a state where it is determined that the first contact has not been resolved (step S40, No). When the position information acquired in S20 changes with the movement of the finger 71 and falls within the cancellation area, it is determined that the second contact has been made (step S30, Yes). Further, since the second contact has been made in the cancellation area, it is determined in step S70 that the cancellation operation has been performed. FIG. 5G shows an example in which the finger 71 touching the touch operation unit 196 is moved to a corner (cancellation region) of the operation panel 11.

<Example of detection area>
FIG. 6 is a diagram illustrating an example in which a non-reactive region that is not detected as the first contact even when the operation part comes into contact with the operation surface 101 is arranged in the operation surface 101. In the example of FIG. 6, the touch operation units 191 to 196 and the slide operation units 110, 120, and 130 with hatched shading are areas where the first contact is detected, and there are no white areas around them. It is a reaction area.

  In an input device in which a plurality of buttons are arranged, when a user performs an operation of pressing a desired button, in an input device that employs a conventional mechanical button, first touch the button lightly to determine that the button is the desired button. After confirming with, an operation such as pressing the button can be performed. On the other hand, in a touch-type input device, some input is started simply by touching the operation surface. Therefore, the user must select a desired button with a finger lifted from the operation surface. In particular, in an input device that employs a capacitance type or optical touch panel, there are cases where a reaction occurs just by bringing a finger close to the operation surface, and it is necessary to sufficiently remove the finger from the operation surface. If you select a button in an unstable state with your finger up like this, you may accidentally press a different button when you actually press the button after you select it. In particular, when an operation such as audio mounted on a vehicle is performed, an input operation may be mistaken due to difficulty in gaze at the operation surface by the user (driver) or the influence of vibration.

  Therefore, in the present embodiment, a non-reactive area is arranged in the operation surface 101, and the user can select an operation target such as a button while touching the non-reactive area and stabilizing the finger. . By providing the non-reaction area in this way, the user can touch the non-reaction area first to adjust his / her posture and then touch a desired button, and the operation can be reliably performed.

  The non-reaction area is not limited to the example of FIG. 6 and can be arbitrarily set as long as it is within the detection range of the touch panel 14 and is an area other than the operation target. For example, the non-reaction region is desirably provided adjacent to at least a part of each operation target, and particularly when a plurality of operation targets are arranged, it is preferably provided between the operation targets. Thus, even when the user is wondering which of a plurality of operation objects to touch, the user can put his finger on the invalid area to adjust his / her posture, and can operate calmly.

  The invalid area may be the outer periphery (edge) or the four corners of the operation surface 101. Thus, by defining the position that is easy for the user to recognize as the invalid area, for example, the user who is driving can place his / her finger in the invalid area without gazing at the operation panel 11, and the operability is improved.

Further, in the example of FIG. 6, a convex index portion 75 protruding from the operation surface 101 is formed in a non-reactive area between the touch operation portion 193 and the touch operation portion 194. As a result, the user can first touch the indicator portion 75 in the non-reactive area, touch the desired button based on the positional relationship with the indicator portion 75, and can reliably perform the operation. For example, if the touch operation unit 193 is touched, the indicator unit 75 is a button on the left side of the indicator unit 75, and if the touch operation unit 195 is touched, the indicator unit is the second button on the right side of the indicator unit 75. The position of each operation target can be grasped from the positional relationship (relative position) with 75, and a desired operation target can be touch-operated. The indicator portion 75 may have a shape different from that of the operation surface 101 other than the indicator portion 75 so that the user can recognize it by tactile sense. It may be a shaped shape.

  In the example of FIG. 6, the non-reactive region is a region where the first contact is not detected, and the second contact detected in step S30 in FIG. 4 and the position information detected in step S60 are in the non-reactive region. Regardless, the entire detection area of the touch panel 14 is detected. As a result, the range for detecting the first contact is limited to secure a place for placing a finger, while the second contact and the canceling operation are not limited to the detection range, and the operation for canceling the first contact is ensured. I can do it.

<Effects of Embodiment>
