Description

  The present invention relates to a touch sensor that detects a touch operation of a finger, and particularly to a touch sensor that is operated without looking at a detection surface.

  Conventionally, touch sensors used by automobile drivers are known. While driving a car, the driver looks at the front of the vehicle and cannot watch the hand. Therefore, it was difficult to know where to touch the touch sensor.

Patent Document 1 discloses an operator control device that allows a driver to perform an appropriate operation without looking away from the front of the vehicle. This operator control device has an operator control panel corresponding to the detection surface of the touch sensor. The operator control panel has a porous matrix with a plunger and an actuator system that moves the plunger up and down electromechanically. The operator control device changes the shape of the operator control panel according to the operation content. As a result, the operator control panel is divided into, for example, relatively small “telephone push button keys” or divided into four relatively large push button keys for direction input. In this way, by changing the shape of the operator control panel according to the operation content, the driver can perceive the operation on the detection surface by touching the unevenness of the panel.
JP-T-2007-513392

  However, since the above-described invention of Patent Document 1 employs a configuration in which the plunger is moved up and down by the actuator system, there is a problem that costs are increased.

  In view of the above background, an object of the present invention is to provide a touch sensor capable of grasping a plurality of operation directions with a tactile sense while suppressing cost with a simple configuration.

  The touch sensor according to the present invention includes an operation guide including a raised portion that guides a finger in a predetermined operation direction on a detection surface touched by the finger, and the operation guide includes a plurality of lines extending in the first operation direction. A first operation direction guide portion formed of a ridge-like ridge portion, and a second operation direction guide formed of a ridge portion extending across the plurality of linear ridge portions in a second operation direction intersecting the first operation direction. Part.

  Thus, since it has the 1st operation direction guide part in which a some linear ridge part extends in the 1st operation direction, a finger can be made to slide in the 1st operation direction by tracing a linear bulge part. . In addition, when the second operation direction guide part is searched by tracing the area including the second operation direction guide part with a finger in the second operation direction, the first operation direction guide intersecting the second operation direction guide part. A plurality of linear bulges of the part are perceived as unevenness, and the second operation direction guide part without unevenness is felt as being recessed. Thereby, the 2nd operation direction guide part which cross | intersects the 1st operation direction guide part can be discovered easily, and a finger can be made to slide in a 2nd operation direction according to a 2nd operation direction guide part. As described above, according to the configuration of the present invention, it is possible to appropriately guide the movement of the fingers in the intersecting first operation direction and the second operation direction.

  In the touch sensor according to the aspect of the invention, the width of the raised portion constituting the second operation direction guide portion with respect to the second operation direction may be narrower than the shortest diameter of the contact surface of the finger with respect to the detection surface.

  With this configuration, when the second operation direction guide portion is touched, the first operation direction guide portion is always touched. Therefore, the second operation direction guide portion can be appropriately found by tracing the region including the second operation direction guide portion with the finger in the second operation direction. The size of the finger contact surface is the size when an average person uses a touch sensor.

  In the touch sensor according to the aspect of the invention, the linear ridges constituting the first operation direction guide portion may have a width such that at least two linear ridges are included in the contact surface of the finger with respect to the detection surface. There may be an interval.

  With this configuration, when the finger is moved along the second operation direction guide part, it is easy to perceive a plurality of linear ridges of the first operation direction guide part as irregularities, and the second operation direction guide part is appropriately Can be found.

  In the touch sensor according to the aspect of the invention, the first operation direction guide portion includes a plurality of concentric raised portions, and the second operation direction guide portion traverses the first operation direction guide portion in a radial direction of the concentric circle. It may be a raised part. Moreover, you may have four 2nd operation direction guide parts which cross the said 1st operation direction guide part up and down, right and left.

  With this configuration, an operation of drawing a circle can be guided by the first operation direction guide unit, and a radial operation across the first operation direction guide unit can be guided by the second operation direction guide unit. In addition, the four second operation direction guide portions that traverse the concentric first operation direction guide portion in the up, down, left, and right directions make it feel as if there are operation buttons in the four directions, up, down, left, and right of the portion without the raised portion at the center of the concentric circle It is done. Thereby, the user can touch the four second operation direction guide portions provided at specific positions on the detection surface without looking at the detection surface.

  The touch-type sensor of the present invention may include a vibration generator that transmits vibration to a finger touching the detection surface.

  With this configuration, feedback can be performed on the finger touching the detection surface. Thus, the user can receive feedback on the operation through the sense of touch without looking at the touch sensor or other monitor.

  The touch sensor of the present invention may be attached to the steering of an automobile.

  With this configuration, the touch sensor can be operated without releasing the hand from the steering wheel. In addition, since the touch sensor has the above-described operation guide, it is possible to slide a finger in an appropriate operation direction on the detection surface without looking at the detection surface, and the driver can operate while looking forward while driving. It can be carried out.

  The vehicle-mounted control apparatus of this invention is equipped with the touch-type sensor of the said description attached to the steering | stirring of a motor vehicle, and the display which displays the content according to operation with respect to the said touch-type sensor.

  With this configuration, the driver can operate the in-vehicle control device while looking forward while driving. Examples of the in-vehicle device operated by the in-vehicle control device include a navigation device, an audio, and an air conditioner. It is desirable that the display is provided at a position where the display can be seen without largely looking away from the front of the vehicle. For example, a head-up display or a windshield display may be used as the display, or the display may be attached to the meter.

  The present invention provides an operation guide having a first operation direction guide portion composed of a plurality of linear ridge portions and a second operation direction guide portion composed of a ridge portion extending across the plurality of linear ridge portions. The structure that suppresses the cost without using the electric drive device has an effect of appropriately guiding the movement of the fingers in the intersecting first operation direction and the second operation direction.

Hereinafter, a touch sensor according to an embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram illustrating a touch sensor 1 according to the first embodiment. The touch sensor 1 is attached to the steering 30 of the automobile. The attachment position of the touch sensor 1 is a position where the driver can operate the touch sensor 1 while holding the steering wheel 30. The touch sensor 1 has a detection surface 10, and when the finger touches the detection surface 10, the touch sensor 1 outputs position data indicating a position touched by the finger.

  FIG. 2 is a diagram illustrating an example of a device control device 40 to which the touch sensor 1 is applied. The device control device 40 may be a device that controls various devices (air conditioner, window, audio, etc.) in the vehicle, or may be a navigation device. In the case of control of an air conditioner, window, audio, etc., there is no need to have a display for displaying information about the operation, but in the case of a navigation device, a map or a selection item is displayed. It is necessary to provide a display. In this case, it is preferable that the navigation device has a display provided at a position where the driver can watch the vehicle while gazing. As such a display, for example, a windshield display or a head-up display can be used. A display may be attached to the meter. Accordingly, the touch sensor 1 can be operated without looking at the hand, and the operation result can be confirmed on the display while looking at the front of the vehicle, so that the navigation device can be operated safely.

  The device control device 40 includes a control unit 42 that controls various devices using a signal from the touch sensor 1. The control unit 42 analyzes the movement trajectory of the finger based on the position data sequentially transmitted from the touch sensor 1 and determines the operation pattern, and the operation for determining the operation content based on the operation pattern. A content determination unit 46 and an instruction command unit 48 that transmits an instruction command to various devices based on the operation content analyzed by the operation content determination unit 46 are provided.

  The operation pattern determination unit 44 first obtains the movement locus of the finger on the detection surface 10 by arranging the position data sequentially received from the touch sensor 1 in time series. Next, the operation pattern determination unit 44 determines to which operation pattern the finger movement trajectory applies. To determine the operation pattern, a reference operation pattern model is prepared in advance, and the operation pattern is determined by matching the model with the movement locus of the finger. In the present embodiment, the operation pattern determination unit 44 determines whether the movement trajectory of the finger matches a circular or straight operation pattern.

  The operation content determination unit 46 determines the operation content based on the current state of various devices and the detected operation pattern. For example, when a rotation operation pattern is detected in a state where a plurality of selection items are displayed on a monitor (not shown), the operation content determination unit 46 selects one item from the selection items. Judged to be an operation. In accordance with this determination, the instruction command unit 48 transmits a command for sequentially focusing the selected items to the monitor. Further, for example, when a straight operation pattern is detected while the audio volume is being adjusted, the operation content determination unit 46 specifies the position where the finger is detected, and sets the volume of the audio based on the position. Send up and down commands. The operation content given here is an example, and the association between the operation pattern and the operation content can be determined by design.

  Next, the configuration of the touch sensor 1 will be described. The touch sensor 1 has an operation guide 12 on the detection surface 10 for guiding operations. The operation guide 12 is constituted by a raised portion having a uniform height. The operation guide 12 guides so as to draw a movement locus that matches the operation pattern on the detection surface 10 and guides the user to easily find a predetermined operation position. The operation guide 12 includes a rotation direction guide portion for guiding a rotation operation and a linear direction guide portion for guiding a linear operation.

  FIG. 3A is a view for explaining the rotation direction guide portion 20, and FIG. 3B is a view for explaining the linear direction guide portion 24. As shown in FIG. 3A, the rotation direction guide portion 20 includes a plurality (six in this example) of linear ridges 22 extending along the rotation operation direction R. That is, the rotation direction guide part 20 is configured by a plurality of concentric ridges. As shown in FIG. 3 (b), the linear direction guide portion 24 is formed from a ridge extending across the plurality of linear ridges 22 constituting the rotational direction guide portion 20 along the linear operation directions L1 to L4. Become. In the present embodiment, there are four linear direction guide portions 24 that cross the rotation direction guide portion 20 in the vertical and horizontal directions. The raised portions 22 and 24 may be integrally formed with the detection surface 10 or may be formed by pasting a film or the like on the detection surface 10.

  Next, the widths of the raised portions 22 and 24 constituting the operation guide 12 and the intervals between the plurality of linear raised portions 22 will be described. The width and interval of the raised portions are set such that the linear guide portion 24 feels depressed when the linear guide portion 24 is traced. If the finger is only on the linear guide 24 when tracing the linear guide 24, the linear guide 24 will not feel depressed. Therefore, in order to make it easy to find the linear direction guide portion 24, it is preferable that the width be such that the finger always touches the linear raised portion 24 when the linear direction guide portion 24 is traced. In other words, the width of the linear guide portion 24 is preferably smaller than the shortest diameter of the finger contact surface. Specifically, the width of the linear guide portion 24 is preferably 2 to 7 mm, and more preferably 3 to 5 mm.

  Further, the reason that the linear guide part 24 feels indented is thought to be because the flat surface of the linear guide part 24 is in the irregularities formed by the plurality of linear raised parts 22. Therefore, it is preferable that the widths and intervals of the plurality of linear raised portions 22 are such widths and intervals that allow the user to feel irregularities when tracing the linear guide portion 24. Specifically, the width of the raised portion is preferably 0.5 to 2 mm, more preferably 0.7 to 1.5 mm, and further preferably 1 mm. The space | interval of a protruding part becomes like this. Preferably it is 0.5-2 mm, More preferably, it is 0.7-1.5 mm, More preferably, it is 1 mm. Moreover, in order to feel that the linear guide part 24 is dented, the length of the linear guide part 24 is preferably 7 mm or more, more preferably 10 mm or more (according to experiments by the present inventors). When the length of the linear guide portion 24 is too short, the linear guide portion 24 does not feel depressed, and when the length is 7 mm or more, some subjects feel that the linear guide portion 24 is depressed to 10 mm or more. As a result, many subjects felt that the linear guide portion 24 was depressed. In addition, the height of the raised portions 22 and 24 is such that the finger can move to a certain degree of smoothness between the non-raised portion and the raised portions 22 and 24, and the raised portion 22 and 24 can be moved from the non-raised portion to the raised portions 22 and 24. What is necessary is just to feel a catch when moving. Specifically, the height of the raised portions 22 and 24 is preferably 0.05 to 0.5 mm, and more preferably 0.1 to 0.3 mm.

  FIG. 4 is a diagram illustrating an example of the intervals between the raised portions 22 and 24 and the plurality of linear raised portions 22 constituting the operation guide 12. The width of the six linear ridges 22 constituting the rotation direction guide portion 20 is 1 mm, and the interval between the ridges 22 is 1 mm. The radius of the innermost linear ridge 22 is 6 mm. Moreover, the width of the four linear direction guide parts 24 which cross the rotation direction guide part 20 up and down, right and left is 4 mm. The height of each raised portion 22, 24 is about 0.2 mm. By designing the operation guide 12 with the dimensions shown in FIG. 4, the rotation direction guide portion 20 and the linear direction guide portion 24 can move in the rotation direction and the linear direction without interfering with the movement of fingers in other operation directions. Can guide the movement of fingers. Note that the dimensions shown in FIG. 4 are an example, and the dimensions of the operation guide provided in the touch sensor of the present invention are not necessarily limited to the example shown in FIG. The touch sensor 1 according to the present embodiment has been described above.

It is possible to guide the movement of the finger to the appropriate. By tracing the rotation direction guide unit 20 with a finger, an appropriate circle can be drawn with the finger without looking at the detection surface 10. In addition, when the region including the linear guide portion 24 is traced in the extending direction of the linear guide portion 24, it is felt that the linear guide portion 24 is indented. Can find out. Thereby, it becomes possible to guide so that a predetermined position on the detection surface 10 can be touched with a finger without looking at the detection surface 10.

A feedback signal transmission unit (hereinafter referred to as “FB signal transmission unit”) 50 is further included. For example, when the operation pattern determination unit 44 determines that the movement locus of the finger matches a predetermined operation pattern, the FB signal transmission unit 50 transmits a feedback signal indicating that the input has been accepted. When vibrator 14 receives the feedback signal transmitted from control unit 42, vibrator 14 vibrates vibrator 14 based on the feedback signal.

  When the vibrator 14 vibrates, the driver who operates the touch sensor 2 can know feedback information (for example, information indicating that an appropriate operation has been performed) through the sense of touch, and therefore, gazes ahead of the vehicle. You can operate while still. The vibrator 14 may perform feedback by changing not only the presence / absence of vibration but also the vibration frequency. Thereby, a plurality of pieces of information can be fed back.
