Description

The present invention relates to a touch sensor controller, a touch sensor unit, and an operation input method.

A technology is used in which a touch sensor is used as an operation switch and the switch can be operated by the user touching it with a fingertip. A mechanical switch causes a failure due to the switch portion being worn or damaged by the switch operation, but the touch sensor switch has an advantage that such a mechanical failure does not occur.

In general, touch sensors are more sensitive to touch operations than mechanical switches. Therefore, the touch sensor is more likely to malfunction than a mechanical switch when touched unintentionally.

JP-A-2002-232770

In the technique of Patent Document 1, even if one finger unintentionally touches one touch sensor and another finger touches the other touch sensor, the switch operation may be mistakenly performed. be. Therefore, there is room for improvement in suppressing malfunctions.

The present invention has been made in view of such a situation, and an object of the present invention is to provide a controller, a touch sensor unit, and an operation input method of a touch sensor capable of suppressing a malfunction with higher accuracy.

In order to solve the above problems, the touch sensor controller according to an embodiment of the present invention has a first touch sensor surface, a second touch sensor surface, and a third touch sensor surface provided on the operation surface, respectively. The contact between the detection unit that detects the contact and the contact on the first touch sensor surface is interrupted, then the contact on the second touch sensor surface is detected, and the contact detection on the second touch sensor surface is interrupted. When a contact on the third touch sensor surface is detected, an operation input unit that accepts a predetermined operation input is provided.

Another aspect of the present invention is a touch sensor unit. This touch sensor unit includes a touch sensor having a first touch sensor surface, a second touch sensor surface, and a third touch sensor surface provided on the operation surface, and a first touch sensor surface and a second touch.

It is a figure which shows another detection example by the touch sensor unit of FIG. It is a figure which shows still another detection example by the touch sensor unit of FIG. It is a figure which shows the other configuration example of a touch sensor.

FIG. 1 is a configuration diagram of the touch sensor unit 100 according to the embodiment. The touch sensor unit 100 functions as a touch sensor switch. The touch sensor unit 100 includes a touch sensor 110 and a controller 120.

The touch sensor 110 is an input device that detects a contact point by a finger or the like and a state quantity such as a capacitance or an electric resistance amount indicating a contact state at the contact point by various methods. The touch sensor 110 is, for example, a capacitance type, a resistive film type, or an infrared type touch sensor. Alternatively, the touch sensor 110 may be an ultrasonic surface acoustic wave type touch sensor composed of a plurality of piezoelectric elements. As an example, the touch sensor 110 may be provided on the vehicle interior side of an automobile door, an operation panel of various devices, or the like, or may be embedded in a wall.

The touch sensor 110 includes a first touch sensor surface (also referred to as A surface) 10a, a second touch sensor surface (also referred to as M surface) 10b, a third touch sensor surface (also referred to as B surface) 10c, and an operation. Includes surface 20. The first, second, and third touch sensor surfaces 10a, 10b, and 10c are collectively referred to as the touch sensor surface 10. The A surface 10a, the M surface 10b, and the B surface 10c are provided on the same operation surface 20. The M surface 10b is arranged between the A surface 10a and the B surface 10c, and can be said to be an intermediate surface. The diameters of the A-side 10a, the M-side 10b, and the B-side 10c are not particularly limited, but may be smaller than the width of the user's finger, for example. The distance between the A surface 10a and the M surface 10b and the distance between the M surface 10b and the B surface 10c are larger than the width of the user's finger. The touch sensor 110 senses whether or not there is contact with each of the A surface 10a, the M surface 10b, and the B surface 10c.

The controller 120 is connected to the touch sensor 110, detects a contact point and a state quantity on the touch sensor 110, and performs predetermined signal processing on the detected signal. The controller 120 determines whether or not a predetermined slide operation of tracing the operation surface 20 has been performed on the touch sensor 110 by a user's fingertip or the like, and if there is a predetermined slide operation, receives a predetermined operation input and the operation input thereof. Put the operation into action. The operation surface 20 can also be called a tracing area. The predetermined slide operation is a first slide operation from the A surface 10a to the B surface 10c via the M surface 10b, or a second slide operation from the B surface 10c to the A surface 10a via the M surface 10b.

The predetermined operation input is an operation input that increases or decreases the operation input amount, for example, adjusting the seat position and seat angle of the automobile, operating the power window of the automobile, setting the temperature of the air conditioner, adjusting the brightness of the lighting, etc. It is an operation input for adjusting the volume, playing and fast-forwarding video and audio equipment, adjusting the screen scroll, and adjusting various setting values.

Hereinafter, the touch sensor 110 for adjusting the front-rear position of the seat of an automobile will be described as an example. That is, the predetermined operation input is an operation input for moving the sheet, which is a predetermined component. It is assumed that the touch sensor 110 is provided on the vehicle interior side of the door of the automobile.

FIG. 2 is a diagram illustrating a configuration example of the touch sensor 110 of FIG. FIG. 3 is a cross-sectional view taken along the line XX'of the touch sensor 110 of FIG.

The operation surface 20 is provided on the convex portion 22 extending linearly in the operation direction. The operating direction is the front-rear direction of the seat, that is, the moving direction of the seat. The side surface 24 of the convex portion 22 is an inclined surface. The user can slide the operation surface 20 after confirming the position of the convex portion 22 by groping without looking at the hand. That is, the touch sensor 110 is easy to operate blindly and is suitable for operation in a dark place.

The operation surface 20 is a concave surface. Therefore, the user can easily recognize the operation surface 20 just by touching it, and can easily perform the slide operation along the recessed area. The boundary between the operation surface 20 and the side surface 24 constitutes a ridgeline. When the ridgeline touches the fingertip, it serves as a guide for the slide operation direction. The user can easily recognize the operation direction and the movement direction of the seat from the shapes of the operation surface 20 and the convex portion 22.

Each of the A surface 10a and the B surface 10c is a convex surface and protrudes from the operation surface 20. The shape of the convex surface is arbitrary, and may be any shape that gives some feel when the user slides the finger. The tactile sensation of the A surface 10a and the B surface 10c is different from the tactile sensation of the operation surface 20. As a result, when the user touches the A surface 10a and then slides to the B surface 10c, or when the user touches the B surface 10c and then slides to the A surface 10a, the user slides from one convex surface to the other convex surface. Since the feeling of the finger that has been done is fed back, the operation feeling that the operation input has been performed is given. Therefore, it is possible to make the user know that the operation input has been accepted.

Since it is only necessary to provide a convex surface on the touch sensor 110, the number of parts is smaller than when mechanical vibration is applied by a vibrating element or the like, and the touch sensor 110 can be manufactured at low cost. There are few.

The M surface 10b constitutes the same surface as the operation surface 20. Therefore, the tactile sensation of the M surface 10b is the same as the tactile sensation of the operation surface 20.

Return to FIG. The controller 120 includes a detection unit 40, a determination unit 50, and an operation input unit 60. These functional configurations can be implemented by hardware, software or a combination thereof.

The detection unit 40 detects the presence or absence of contact with the touch sensor 110 by a fingertip or the like. The detection unit 40 detects contact on each of the A surface 10a, the M surface 10b, and the B surface 10c.

The determination unit 50 determines the contact on the M surface 10b after the detection of the contact on the A surface 10a is interrupted within a predetermined time after the contact on the A surface 10a is detected based on the presence or absence of the contact detected by the detection unit 40. Is detected, and if the contact on the B surface 10c is detected after the detection of the contact on the M surface 10b is interrupted, it is determined that the first slide operation has been performed, and the duration of the contact detection on the B surface 10c is continued. To get.

Further, the determination unit 50 detects the contact on the M surface 10b after the detection of the contact on the B surface 10c is interrupted within a predetermined time after the contact on the B surface 10c is detected, and the contact on the M surface 10b is detected. When the contact on the A surface 10a is detected after the detection is interrupted, it is determined that the second slide operation has been performed, and the duration of the contact detection on the A surface 10a is acquired.

The predetermined time is not particularly limited, but may be, for example, 1 to 2 seconds or less, and the optimum value can be appropriately determined by an experiment.

When the determination unit 50 determines that the slide operation has been performed, the operation input unit 60 receives a predetermined operation input corresponding to the slide operation and executes it. For example, the operation input unit 60 receives an operation input for moving the seat in the forward direction in response to the first slide operation, and controls the operation so that the operation is executed. Further, the operation input unit 60 receives an operation input for moving the seat in the backward direction in response to the second slide operation, and controls the operation so that the operation is executed. When the first slide operation is performed, the operation input unit 60 increases the operation input amount as the duration is longer, and when the second slide operation is performed, the operation input amount decreases as the duration is longer. The operation input amount represents the position of the seat, and the larger the amount, the more the seat is located in the front, and the smaller the amount, the more the seat is located in the rear.

If the contact on each of the M surface 10b and the B surface 10c is not detected within a predetermined time after the contact on the A surface 10a is detected, the determination unit 50 determines that the first slide operation is incomplete. .. If the contact on each of the M surface 10b and the A surface 10a is not detected within a predetermined time after the contact on the B surface 10c is detected, the determination unit 50 determines that the second slide operation is incomplete. .. When the determination unit 50 determines that the slide operation is incomplete, the operation input unit 60 cancels the acceptance of the operation input. As a result, erroneous input can be suppressed when the touch sensor surface is unintentionally touched.

FIG. 4 shows an example of detection by the touch sensor unit 100 of FIG. FIG. 4 shows an example in which the user advances the seat by one notch or a plurality of notches. The user slides on the operation surface 20 from the A surface 10a to the B surface 10c. The contact on the A surface 10a is detected, the contact on the M surface 10b is detected after the detection of the contact on the A surface 10a is interrupted, and the contact on the B surface 10c is detected after the detection of the contact on the M surface 10b is interrupted. ing. Since the time t1 from the detection of the contact on the A surface 10a to the detection of the contact on the B surface 10c is shorter than the predetermined time, the operation input for advancing the seat is accepted.

In the example shown by the solid line, the time t2 from the detection of the contact on the B surface 10c to the interruption of the contact detection is shorter than the predetermined reference time. Therefore, the seat is advanced by one notch. This operation can also be called a single push or click on the B side 10c.

On the other hand, in the example shown by the broken line, the time t2'from the detection of the contact on the B surface 10c to the interruption of the contact detection is longer than the reference time. Therefore, the seat is advanced by a plurality of notches according to the time t2'. This operation can also be called a long press or hold on the B surface 10c.

In this way, after performing the slide operation, the operation input amount can be adjusted while touching the touch sensor 110.

If the touch sensor surface 10 is touched in any order other than the above order after the A surface 10a is touched, the acceptance of the operation input is canceled and the determination is restarted from the touched position at the time of cancellation. This is because (1) when the operation input unit 60 detects the contact on the A surface 10a or the B surface 10c without detecting the contact on the M surface 10b after the detection of the contact on the A surface 10a is interrupted, or (2) When the contact on the M surface 10b is detected after the detection of the contact on the A surface 10a is interrupted, and the contact on the A surface 10a or the M surface 10b is detected after the detection of the contact on the M surface 10b is interrupted. Corresponds to canceling the operation input.

Similarly, in the operation input unit 60, (1) when the contact on the A surface 10a or the B surface 10c is detected without detecting the contact on the M surface 10b after the detection of the contact on the B surface 10c is interrupted, or ( 2) When the contact on the M surface 10b is detected after the detection of the contact on the B surface 10c is interrupted, and the contact on the B surface 10c or the M surface 10b is detected after the detection of the contact on the M surface 10b is interrupted, the operation is performed. Cancel the input. As a result, erroneous input can be suppressed when the touch sensor surface 10 is unintentionally touched.

FIG. 5 shows another detection example by the touch sensor unit 100 of FIG. FIG. 5 shows an example in which the user keeps advancing the seat and then retracts the over-advanced seat by one notch or a plurality of notches. The user slides the operation surface 20 from the A surface 10a to the B surface 10c, keeps touching the B surface 10c, and then slides the operation surface 20 from the B surface 10c to the A surface 10a. The user has not released his finger from the operation surface 20 until he starts from the A surface 10a and returns to the A surface 10a.

It is the same as the example of the broken line in FIG. 4 until the passage of time t2'. When returning from the B surface 10c to the A surface 10a, the contact on the M surface 10b is detected after the detection of the contact on the B surface 10c is interrupted, and the contact on the A surface 10a is detected after the detection of the contact on the M surface 10b is interrupted. It has been detected. Since the time t3 from the interruption of the contact detection on the B surface 10c to the detection of the contact on the A surface 10a is shorter than the predetermined time, the operation input is accepted.

This is because, when the operation input unit 60 receives a predetermined operation input, the contact on the M surface 10b is detected after the contact detection on the B surface 10c is interrupted, and the contact detection on the M surface 10b is interrupted. When the contact on the A surface 10a is detected after that, it corresponds to accepting an operation input different from the predetermined operation input.

By detecting the contact on the M surface 10b, it is possible to determine the switching of the slide operation direction, that is, the switching of the input operation without impairing the continuity of the slide operation. Therefore, after performing a predetermined operation input while touching the touch sensor 110, it is possible to perform a different operation input.

In the example shown by the solid line, the time t4 from the detection of the second contact on the A surface 10a to the interruption of the contact detection is shorter than the predetermined reference time. Therefore, the seat is retracted by one notch.

On the other hand, in the example shown by the broken line, the time t4'from the detection of the second contact on the A surface 10a to the interruption of the contact detection is longer than the predetermined reference time. Therefore, the seat is retracted by a plurality of notches according to the time t4'.

FIG. 6 shows yet another detection example by the touch sensor unit 100 of FIG. FIG. 6 is also an example in which the user continues to advance the seat and then retracts the excessively advanced seat by one notch or a plurality of notches. The user slides on the operation surface 20 from the A surface 10a to the B surface 10c, keeps touching the B surface 10c, releases the finger from the operation surface 20 once, and then touches the B surface 10c again to touch the A surface 10a. Slide on the operation surface 20 until.

It is the same as the example of the broken line in FIG. 4 until the passage of time t2'. After the detection of the contact on the B surface 10c is interrupted, the contact on the B surface 10c is detected again, and after the re-detection of the contact on the B surface 10c is interrupted, the contact on the M surface 10b is detected, and the contact on the M surface 10b is interrupted. The contact on the A surface 10a is detected after the detection of the above is interrupted. Since the time t3'from the detection of the contact on the B surface 10c to the detection of the contact on the A surface 10a is shorter than the predetermined time, the operation input is accepted. Subsequent processing on the A surface 10a is the same as in FIG.

This is because when the operation input unit 60 receives a predetermined operation input, the contact on the B surface 10c is interrupted and then the contact on the B surface 10c is detected again, and the contact detection on the B surface 10c is interrupted. If the contact on the M surface 10b is detected after that, and the contact on the A surface 10a is detected after the detection of the contact on the M surface 10b is interrupted, it corresponds to accepting an operation input different from the predetermined operation input. do.

As a result, after performing a predetermined operation input, it is possible to continuously perform a different operation input.

Since the operation input is not accepted unless the three touch sensor surfaces 10 are touched in a predetermined order in this way, it is possible to prevent the switch from malfunctioning when one or more touch sensor surfaces 10 are unintentionally touched.

In addition, since it requires an active operation that the user must pay attention to, that is, touching the three touch sensor surfaces 10 in sequence during operation, the operation can be performed by touching only one place, as compared with the conventional touch switch. , The user clearly recognizes that the operation input has been made.

Further, the determination unit 50 detects the contact on the M surface 10b before the detection of the contact on the A surface 10a is interrupted, or the contact on the B surface 10c before the detection of the contact on the M surface 10b is interrupted. Even in this case, it is determined that the touch operation is incomplete. When the determination unit 50 detects the contact on the M surface 10b before the detection of the contact on the B surface 10c is interrupted, or when the contact on the A surface 10a is detected before the detection of the contact on the M surface 10b is interrupted. It is also determined that the touch operation is incomplete. That is, when contact is detected on both the A surface 10a and the M surface 10b, or on both the M surface 10b and the B surface 10c at the same time, it is determined that the touch operation is incomplete.

Since the distance between the A side 10a and the M side 10b and the distance between the M side 10b and the B side 10c are larger than the width of the finger, in the slide operation intended for the switch operation, both the A side 10a and the M side 10b are contacted at the same time. It is assumed that they do not come into contact with both the M surface 10b and the B surface 10c at the same time.

On the other hand, it is possible to suppress a malfunction in which an operation input is erroneously accepted when the A-side 10a, the M-side 10b, and the B-side 10c are unintentionally touched by a plurality of fingers instead of the slide operation. Therefore, malfunction can be suppressed with higher accuracy.

FIG. 7 shows another configuration example of the touch sensor 110. In addition to the touch sensor 110 described above, the touch sensor 110a, the touch sensor 110b, and the touch sensor 110c are provided inside the door of the automobile. The difference from the touch sensor 110 will be mainly described.

The touch sensor 110a receives an operation input for adjusting the angle of the seat surface of the seat. The touch sensor 110b receives an operation input for adjusting the angle of the backrest of the seat. The touch sensor 110c receives an operation input for adjusting the angle of the headrest of the seat. That is, the predetermined operation input is an operation input for tilting the seat surface, the backrest, or the headrest of the seat.

In the touch sensor 110a, the operation direction of the slide operation is the tilting direction of the seat surface of the seat. In the touch sensor 110b, the operating direction is the tilting direction of the backrest of the seat. In the touch sensor 110c, the operating direction is the tilting direction of the seat headrest.

The convex portion 22a extends in an arc shape along the operation direction. The operation surface 20a also extends in an arc shape along the operation direction. The A side 10a, the M side 10b, and the B side 10c are arranged along the operation direction. Therefore, the user can recognize the operation direction and the tilt direction of each part of the seat from the shapes of the operation surface 20a and the convex portion 22a.

Other effects of the above touch sensor unit 100 will be described.

(1) Hard to break down Since the touch sensor 110 of the present embodiment does not have a movable mechanism such as a normal button or switch, the device is not deformed or damaged due to it, and it is hard to break down. ..

(2) Can be manufactured at low cost The touch sensor 110 of the present embodiment is composed of an existing inexpensive member, which is a component representing the shape of a switch and a touch sensor. In addition, since it does not require a complicated mechanical mechanism, the labor required for processing is less than that for manufacturing a general switch. These features make it possible to manufacture the touch sensor unit 100 at low cost.

(3) Easy to expand the application environment Since the touch sensor 110 of the present embodiment has a relatively simple structure, it is not easily restricted in size and shape. As a result, the degree of freedom in size and shape is increased, so that it can be installed in a narrow place or on a curved surface, and can be applied to various environments and situations. Further, in general, when a movable switch member is present in a certain device, water and dust enter from a gap portion necessary for moving the switch, so that it becomes difficult to ensure dustproofness and waterproofness. Since the touch sensor unit 100 of the present embodiment does not have a movable mechanism, the airtightness of the switch can be ensured by a simple coating, and it is easy to raise the protection grade such as dustproof and waterproof. When considering waterproofness, it is necessary that the sensing method of the touch sensor on the operation surface is not a capacitance but a resistance film or the like that is not easily affected by water wetting.

The present invention has been described above based on the embodiments. This embodiment is an example, and it is understood by those skilled in the art that various modifications are possible for each of these components and combinations of each processing process, and that such modifications are also within the scope of the present invention. be.

For example, a plurality of M surfaces 10b may be provided between the A surface 10a and the B surface 10c. An example of two M surfaces 10b will be described. The operation input unit 60 detects the contact on one M surface 10b after the contact detection on the A surface 10a is interrupted, and after the contact detection on the one M surface 10b is interrupted, the contact on the other M surface 10b is detected. When the contact on the other M surface 10b is detected and the contact on the B surface 10c is detected after the detection of the contact on the other M surface 10b is interrupted, a predetermined operation input is accepted. According to this modification, malfunction can be suppressed with higher accuracy.

Further, the operation input unit 60 determines when the contact on the M surface 10b is not detected within a predetermined first time after the contact on the A surface 10a is detected, or after the contact on the M surface 10b is detected. If the contact on the B surface 10c is not detected within the second time, the predetermined operation input may be canceled. In this case, the degree of freedom in the configuration of the controller 120 can be improved.
