JP6915815B2 - Electronic information system and its programs - Google Patents

Description

The present invention relates to an electronic information system and a program thereof.

Conventionally, as an electronic information system, for example, there are electronic devices capable of acquiring driving information such as a navigation device mounted on a vehicle such as an automobile or a bicycle and a microwave receiver (radar detector) mounted on the automobile. Further, as an electronic information system capable of acquiring various information used daily, there are electronic devices such as smartphones and personal computers.
In these electronic information systems, users acquire information by pressing an input switch attached to the device to input information, or by actually touching and operating the operating means. I try to do it. Patent Documents 1 and 2 are given as electronic information systems provided with such conventional input means and operating means.
The electronic device of Patent Document 1 is a drive recorder device attached to the windshield of an automobile with double-sided tape or the like. As shown in FIG. 3, the drive recorder device includes a switch unit 20, a display unit 21, and a volume dial 23.
Further, the electronic device of Patent Document 2 is a microwave detection device that also serves as a rear-view mirror attached to a rear-view mirror that is arranged by default in an automobile. In this device, various information is displayed on the display panel 13 which is a part of the mirror surface by touching the touch screen 16 which also serves as the mirror surface and performing an input operation.

JP-A-2010-105530 Japanese Unexamined Patent Publication No. 2012-66640

However, in the drive recorder device of Patent Document 1, for example, since the volume dial 23 as an operating means is attached to the housing as a separate component, the weight of the component related to the volume dial 23 is added to increase the weight of the device. .. Weight increase is not preferable when it is attached to the windshield by such an adhesive method. In addition, the number of parts will increase, which will lead to higher costs. On the other hand, in the microwave detection device of Patent Document 2, since the touch screen 16 also serving as a mirror surface is used as an operation means, the number of parts related to operation is reduced and the weight is reduced, but the input is input unless the mirror surface is actually touched. This is not possible, and touching it may stain the mirror surface.
For these reasons, there has been a demand for a means in which an operating member for acquiring information in an electronic information system is unnecessary or can be reduced, and information can be acquired without directly contacting a device. Therefore, there is a device that recognizes a user's gesture and performs a predetermined process based on the recognition result. However, in such a device, for example, the user self-self only when the notification indicating the success or failure of the recognition of the gesture is made or when the device notifies that the predetermined processing corresponding to the gesture is started. There was a problem that it was possible to grasp that the gesture of was correct, and it was difficult to judge whether the gesture movement of oneself was correct and recognizable by the device while making the gesture. .. For example, in spite of the state of an unrecognizable gesture of the device, the user may think that the device is in the state of a recognizable gesture and try the same gesture over and over again. For example, as the state of the gesture, the movement of the gesture is a movement that can be recognized by the device, but it is remarkable in a case where the device cannot recognize because the recognition target such as the user's hand is in a position where the device cannot recognize. There was a problem.
The present invention has been made to solve the above problems, and an object of the present invention is an electronic information system and a program thereof capable of realizing a desired function in a device more reliably than before without directly contacting the device. Is to provide.

In order to achieve the above object, as means 1, an electronic information system that performs a predetermined process based on a gesture recognition result by a user is provided with a control means that controls output of a sound during gesture recognition. Is good.
With such a configuration, the user can know by sound that the gesture is being recognized. Therefore, it is possible to make the device execute the desired process more reliably than before. Therefore, it is possible to realize the desired function in the device more reliably than in the past. Further, for example, when the gesture is not being recognized, at least one of a configuration that outputs a sound different from that during the gesture recognition or a configuration that does not output a sound may be provided. In this way, the user can know by sound whether or not the gesture is being recognized. In addition, since the sound is output during the recognition of the gesture, it is possible to train the gesture by performing the gesture so as to output this sound. Further, it is preferable to output a sound indicating whether or not the gesture recognition is successful, and make the sound different from the sound indicating whether or not the gesture recognition is successful and the sound output during the recognition of the gesture. In this way, the user can more reliably know whether or not the gesture is being recognized and whether or not the gesture recognition is successful. Therefore, the user can more reliably know by sound whether or not the gesture is being recognized, and makes a gesture so as to output a sound indicating that the gesture is being recognized, and as a result, outputs a sound indicating that the gesture is successful. It is also possible to train gestures to ensure that the user can achieve the desired function, such as practicing to make them perform.

Here, "performing a predetermined process based on the recognition result of the gesture" may be configured to perform a predetermined process according to the mode of the gesture after the gesture is recognized, for example, there is a predetermined process. It is preferable to configure the gesture to be realized as input information. Here, the "predetermined process" may be configured to provide information from the electronic information system, which is performed as a result of recognizing the gesture, for example. As a more specific predetermined process, for example, as an auditory process, for example, it is preferable to generate a sound, change the volume, or the like. The sound may be configured to include, for example, an alarm sound, information transmission by voice guidance such as "please be careful", music, etc., regardless of whether or not there is a scale. Further, for example, it is preferable to display information on the display screen as a visual process, erase the displayed information, change the displayed information, and the like. Further, it is preferable that the recognition result of the gesture drives some actuator to perform mechanical or pneumatic control. For example, the lock device may be unlocked or locked, or the door may be opened or closed. It is preferable to have a configuration in which a plurality of different gestures are recognized and different functions are realized depending on the recognized gestures. For example, it is preferable to recognize a plurality of different gestures and perform different processing depending on the recognized gestures. In particular, in a configuration having a function of recognizing a plurality of different gestures and performing different processing depending on the recognized gesture, it is preferable to output different sounds while recognizing different gestures. In this way, the user can understand which process may be performed while recognizing the gesture. In particular, as a configuration for outputting different sounds while recognizing different gestures, it is preferable to output different sounds in the process of different gestures. In this way, the user can determine whether or not the gesture is being recognized correctly in the process of completing the recognition of the gesture. Therefore, when it is recognized as a process of an erroneous gesture, it is recognized as an unintended gesture by stopping the gesture in the middle, and as a result, an unintended process is executed and an unintended function is realized. , Can be prevented during gestures.
The "gesture recognition" may be, for example, a part of the gesture recognition, but may be the majority of the gesture recognition, or the whole gesture recognition. In particular, "gesture recognition in progress" may be set while the gesture is being recognized in the gesture recognition process. Further, in particular, it is preferable to continuously output the sound while the gesture is recognized in the gesture recognition process. In particular, even in a configuration in which the sound is changed during recognition, it is preferable to continuously output the sound so that the sound is not interrupted when the sound is changed.
In this way, it can be seen that the gesture recognition has started when the sound during the gesture recognition starts, and the gesture recognition is interrupted when the sound during the gesture recognition is interrupted. Therefore, the user can more surely realize the desired function, and gesture training becomes easier.
The "electronic information system" may be, for example, a system that can be installed in a vehicle, carried by a user, or installed indoors so that the user can access and acquire information. The electronic information system mounted on the vehicle may be, for example, an electronic device such as a navigation device, a radar detection device, or a drive recorder. As the electronic information system carried by the user or installed indoors, for example, a smartphone, a personal computer, a TV device, an AV device, or the like may be used.

Further, as the means 2, the control means may output sounds at different timings during the recognition of the gesture.
By outputting not only one sound but a plurality of times at different timings in this way, it is possible to more reliably grasp that the gesture is being recognized. In particular, the "different timing" may be a timing indicating the gesture recognition process. In this way, the user can grasp the gesture recognition process from whether or not different sounds are output. Further, for example, the "different timing" may be the timing at which a change in the position of the object to be recognized is detected. In this way, the user can easily grasp by sound whether the position of the object is moving to an appropriate position. Further, the sounds output at different timings may be configured to create different sound patterns according to a predetermined process, for example. In this way, the user can easily understand and confirm the content of the predetermined process from the sound pattern. In addition, even if the user does not actually recognize the content of the predetermined process, it is possible to understand that various sound patterns are output in relation to the predetermined process, and the user actually touches the operation means. You can feel the unprecedented operational interest compared to the case of doing.
Further, as the means 3, the sounds output at the different timings may include different types of sounds.
By outputting different types of sounds as sounds output at a plurality of different timings in this way, the sound pattern can be varied and the user's ability to recognize the sound pattern is improved. As the "different types of sounds", for example, the tones (high and low) of the sounds may be different, the sound quality (timbre) may be different, or different types of sounds may be mixed. Even the same tone can be recognized as different types of sounds by changing the sound quality. Also, as in the above, it is possible to understand that different types of sounds are output in relation to the predetermined processing even if the user does not actually recognize the content of the predetermined processing in relation to the sound. It is possible, and you can feel the unprecedented operational interest compared to when you actually touch the operating means.
Further, as the means 4, the sounds output at the different timings may include different types of sounds according to the difference in the approach distance to the gesture detecting means for recognizing the gesture.
By generating different types of sounds according to the difference in approach distance in this way, the user can recognize the degree of approach to the gesture detecting means by the sound. In addition, even if the user does not actually recognize the relationship between the sound and the degree of approach, different types of sounds are output along with the gesture, which is unprecedented compared to the case of actually touching the operation means. You can feel the fun of operation. There are several methods of detection devices as "gesture detection means". For example, a gesture sensor is a detection device equipped with a gesture sensor that irradiates an object with infrared light from an infrared light emitting element and captures a change in the reflected light with a light receiving element to detect the movement of the object. Instead, a detection device equipped with a gesture sensor using infrared rays, a detection device equipped with a gesture sensor using a change in capacitance due to gestures, and the like can be used. The approach distance may be the distance between the recognition object and the detection device of the gesture detecting means. The object to be recognized can be various objects, for example, a stick, but it is preferable that the object is a part of the human body. Especially good for hands.

Further, as the means 5, the control means may output the sound based on a gesture of stopping for a certain period of time or longer.
Since such a gesture of stopping is a gesture that is very easy for the user to understand and can be easily learned, it may be a gesture to be performed by the user. The fixed time to stop, which is a condition for outputting sound, is a length that the user can understand as having stopped, and may be, for example, about several seconds. For example, it is advisable to change this length by changing the setting. Further, the stop position may be detected at some point in an area having a certain width as long as the gesture detecting means can detect it.
For example, it may be near or far from the gesture detection means. Further, the same predetermined processing may be performed regardless of the difference in the approach distance to the gesture detecting means, but it is preferable to perform different predetermined processing depending on the difference in the approach distance to the gesture detecting means. When different predetermined processes are performed, it is preferable to output different sounds according to the difference in the processes. In this way, the user can easily grasp which gesture the recognition stop position corresponds to and which process is expected to be executed during gesture recognition. Therefore, as a result of the recognizing gesture being recognized as different from the user's intention, it is possible to effectively prevent the user's unintended processing from being executed. Furthermore, it is easy to understand which gesture is recognized and which process is executed when the user stops at which position.
Further, as the means 6, the control means may output the sound based on a gesture of stopping for a certain period of time or more after the movement.
Since the gesture of stopping for a certain period of time or more after such a movement is also a gesture that is very easy for the user to understand and can be easily learned, it may be a gesture to be performed by the user. Specifically, for example, it is preferable to move the gesture detecting means so as to cross the front of the gesture detecting means and make a gesture to stop the gesture detecting means at a detectable position.

Further, as the means 7, it is preferable to associate the gesture pattern with the output sound.
As a result, the user can understand the content of a predetermined process by executing a certain gesture and listening to a certain pattern of sound output. Further, it can be understood that various sound patterns are output in relation to the predetermined processing even if the user does not actually recognize the content of the predetermined processing. In addition, compared to the case of actually touching the operating means, it is possible to feel an unprecedented operational interest. Here, as the "sound", for example, it is preferable to output as a melody by outputting a sound of a certain scale only once or a plurality of times, or to output the same scale or melody in a pattern different only in sound quality. In this way, the user can easily grasp which gesture pattern corresponds to which sound and which process is expected to be executed based on the sound during gesture recognition. Therefore, as a result of the recognizing gesture being recognized as different from the user's intention, it is possible to effectively prevent the user's unintended processing from being executed.
Further, as the means 8, regardless of the gesture pattern, it is preferable to output a plurality of the same sounds according to the detected distance during the recognition of the gesture.
This allows the user to recognize that they are stopped at a certain distance, for example, when they perform a stop gesture, by repeating the same sound, for example, the hand is shaking or the hand cannot be stopped properly due to vibration. In such a case, it becomes possible to objectively recognize whether or not the device has "stopped".
Further, as the means 9, it is preferable to output a different kind of sound for each different predetermined process after the gesture is recognized, depending on the difference in the predetermined process to be executed after the gesture is recognized.
This allows the user to understand the content of a predetermined process to be executed by listening to different sounds output as a result of executing a certain gesture. Further, it can be understood that various sounds are output in relation to the predetermined process even if the user does not actually recognize the content of the predetermined process. In addition, compared to the case of actually touching the operating means, it is possible to feel an unprecedented operational interest. Here, as the "sound", for example, it is preferable to output as a melody by outputting a sound of a certain scale only once or by outputting a plurality of times, or to output the same scale or melody in a pattern different only in sound quality.

Further, as the means 10, it is preferable that the control means generate a sound according to the distance at the time of a gesture of approaching from a distance.
Further, as the means 11, the control means may generate a sound according to the distance at the time of a gesture of separating the distance.
By generating a sound according to the difference in approach distance during a gesture of approaching from a distance or a gesture of moving away from a distance as described above, the user can perform a predetermined process performed by such a gesture by the sound accompanying the gesture. Can be recognized.
For example, when approaching from a distance below, a certain sound pattern is output and the volume output by the device is increased, and when moving away from a distance below, a different sound pattern is output and the volume is decreased. It's like that.
Here, there may be one sound or a plurality of sounds according to the difference in approach distance. It may also contain different types of sounds. If there are a plurality of sounds, the number of sound patterns will increase, and it will be easier for the user to understand and confirm the content of a predetermined process from the sounds. As a gesture, it may be a series of gestures that approach from a distance and separate from the distance as it is.

Further, as the means 12, the control means may generate a sound according to the approaching direction at the time of a gesture of approaching from a distance.
Further, as the means 13, it is preferable that the control means generate a sound according to the separation direction at the time of the gesture of separating the distance.
By generating a sound according to the difference in the approaching direction at the time of a gesture of approaching from a distance or a gesture of moving away from a distance as described above, the user can perform a predetermined process performed by such a gesture as a sound associated with the gesture. It can be recognized by the relationship with. For example, when approaching from a distance below, a certain sound pattern is output and the volume is increased, and when approaching from a distance above, a different sound pattern is output and the volume is decreased. Alternatively, when the distance is far below, a certain sound pattern is output and the amount of light on the display screen is increased, and when the distance is far above, a different sound pattern is output and the amount of light on the display screen is increased. It's like making it smaller. In other words, different processing is performed for each unique sound depending on the difference in gesture, and the user can hear the sound and recognize that the processing according to the sound has been performed. Further, even if the user does not actually recognize the content of the predetermined process in relation to the sound, it can be understood that various sounds are output in relation to the predetermined process, and the sound differs depending on the direction. Because of this, you can feel the unprecedented operational interest compared to when you actually touch the operating means. The number of sounds according to the difference in approach distance may be one or a plurality as described above. It may also contain different types of sounds.

Further, as the means 14, it is preferable to have a first spatial region in which a gesture by the user can be detected and control for outputting a sound is performed.
By having such a space area, for example, when a user installs a device related to an electronic information system, it is mistakenly recognized as a member or a user's gesture movement that hinders the gesture in this space area. It is possible to prevent the existence of such an object. The first spatial region is generally recognized as a region that can be detected by the gesture detecting means. The approach to the first spatial region may be a three-dimensional space at an equal distance from the gesture detecting means.
Further, as the means 15, it is preferable that the detectable distance of the first spatial region can be changed.
With such a configuration, the first space is considered in consideration of a situation in which, for example, there are a member that interferes with the gesture or an object that is mistakenly recognized as the movement of the user's gesture. It is possible to make settings according to the situation, such as narrowing the area or widening the first spatial area so that the user can easily detect the gesture even if the user is away from the device.
Further, as the means 16, the control means extends the first spatial region to a relatively wide spatial region in a predetermined information mode, and relative to the first spatial region in cases other than the predetermined information mode. It is preferable to control the reduction to a narrow space area.
Such a configuration contributes to the ease of gestures of the user when trying to respond according to a predetermined information mode. As the predetermined information mode, for example, it is preferable to include a mode in which an operation with higher urgency is performed than in a case other than the predetermined information mode. For example, suppose that there is a "state in which an alarm is notified while driving a car" as a predetermined information mode. Specifically, for example, when an alarm indicating that some road traffic information (for example, N system) has been detected from a radar detection device as an electronic device is notified. In this case, after recognizing this notification, the user may want to cancel the notification state of the alarm because the alarm to be continuously notified is no longer necessary. In other words, although it is necessary information, since the user has recognized it, further information provision operations are excessive and not necessary. In this case, since you are driving, the gesture for canceling should be simple and not exaggerated as much as possible. Therefore, even if the first space area is usually set to a relatively narrow space area so that an action such as carelessly holding a hand is not recognized as a gesture, the first space area is accompanied by an alarm notification. By making the space area relatively large, the user can perform gestures without reaching too far.

Further, as the means 17, it is preferable to have a second spatial region in which the moving direction of the gesture by the user can be detected and the sound is output.
By having such a spatial area, for example, it becomes possible to recognize from which direction the hand making the gesture of the user is coming from which direction, and therefore, a different predetermined process is selected according to the direction. It becomes possible to do. Then, the user can recognize a predetermined process in relation to the sound according to the direction. In addition, even if the user does not actually recognize the content of the predetermined process in relation to the different sounds, it can be understood that various sounds are output in relation to the predetermined process, and the actual operation can be performed. Compared to touching the means, you can feel the unprecedented operational interest. For example, when moving from far downward to upward, a certain sound pattern is output and the volume is increased, and when moving from far upward to downward, a different sound pattern is output and the volume is decreased. It's like doing.
The moving direction with respect to the second spatial region may include not only a flat 360-degree direction but also a three-dimensional direction. This will increase the variation in the moving direction.
Further, as the means 18, it is preferable that the detectable distance of the second spatial region can be changed.
With such a configuration, for example, in consideration of the situation where the user may mistakenly recognize a member that hinders the gesture or the movement of the user's gesture, the second The user can make settings according to the situation, such as narrowing the space area of the space, or widening the second space area so that it can be detected as easily as possible even if it is far from the device when gesturing. The user can set the optimum gesture environment to execute a predetermined process.
Further, as the means 19, the second spatial region may be inside the first spatial region.
As a result, when the gesture is performed, the gesture is first recognized in the first space area in order, and further, when the gesture enters the second space area, it is determined from which side the gesture is approached. Since the spatial areas are not separate but overlapped in this way, the spatial area in which the user makes a gesture does not unnecessarily expand, which contributes to the compactification of the area in which the user makes a gesture. On the contrary, if the second space area is outside the first space area, when entering the first space area, it is necessary to enter the second space area having the direction of approach. , There is a possibility that the user will be in a predetermined processing mode that is not planned.

Further, as the means 20, it is preferable to change the volume set as the predetermined process.
This shows an example of a specific predetermined process. That is, the sound is output during the recognition of the gesture, and the volume is changed by recognizing the gesture. This saves the user the hassle of finding and manipulating the volume to adjust the volume.
To give a more specific control example, a gesture that moves from one direction to another (for example, hold your hand from the bottom to the top over the gesture detection means. The user can recognize an object that can recognize the movement without a hand. You can raise the volume by a certain amount by holding it up, and you can lower the volume by a certain amount by a gesture that moves from one direction to another (for example, by holding your hand from top to bottom). be.
In addition, a special gesture may be used to change the volume so that it is not a constant amount. For example, by changing the speed of movement from one direction to a certain direction, such as by holding a hand, the volume to be changed can be increased, or by stopping the movement in the middle and continuously changing the volume during that time. be.

Further, as the means 21, it is preferable to suppress the notification of the information currently being notified as the predetermined process.
This also shows an example of a specific predetermined process. That is, the sound is output during the recognition of the gesture, and the recognition of the gesture suppresses the notification of the alarm information currently being notified. As a result, the user can cancel the notification of unnecessary information with a simple operation. Here, "notification of alarm information" is, for example, an alarm sound, voice guidance of an alarm, a display to that effect on a display screen, or the like. "Suppressing notification" means reducing the volume or muting the sound for voice notification, and reducing the brightness or turning off the display screen for visual notification.
For example, an alarm while driving a car will be described as an example. For example, when an alarm indicating that some road traffic information (for example, N system) has been detected from a radar detector as an electronic device is notified, the user does not need the alarm to be continuously notified after recognizing this notification. You may want to cancel the alert status. In other words, although it is necessary information, since the user has recognized it, more information is excessive and unnecessary. In this case, it is significant to suppress the alarm sound.
To give a more specific example of control, the user holds his hand at a detectable position (for example, the first spatial region described above) (it does not have to be a hand as described above) and stops at that position for a predetermined time. Make a gesture that makes you want. Recognizing this gesture is like stopping the currently notified alarm sound. At this time, for example, when the detectable area set by the user is narrow, it may be controlled so that the area is temporarily widened to facilitate detection. This is because it is better to have a wide area for quick operation depending on the situation.

Further, as the means 22, it is preferable to display information on the display screen as the predetermined process.
This also shows an example of a specific predetermined process. That is, the sound is output during the recognition of the gesture, and the information is displayed on the display screen when the gesture is recognized. This eliminates the hassle of finding an operating means for displaying information on the display screen and operating it to change the volume.
Further, as the means 23, it is preferable to change the information displayed on the display screen as the predetermined process.
This also shows an example of a specific predetermined process. That is, the sound is output during the recognition of the gesture, and the information displayed on the display screen is changed by recognizing the gesture. As a result, the user does not have to search for an operation means for changing the information on the display screen and operate it to change the volume.

Further, as the means 24, the control means displays a first display mode as a starting point on the display screen, changes to another display mode based on the recognition result of the predetermined gesture, and then recognizes the predetermined gesture. It is preferable to control so that the first display mode is displayed again based on the result.
This indicates a control for returning to the first display mode, which is the initial screen, as a result of performing gestures one after another. With such a configuration, the user can easily understand the appearance order of the display mode that can be changed by the gesture based on the appearance order of the first display mode. It is advantageous when there are many setting screens as the first display mode.
Further, as the means 25, the electronic device mounted on the vehicle also serves as a rear-view mirror, and the gesture by the user may be performed in front of the rear-view mirror.
This is because mounting an electronic device for mounting on the vehicle on the rear-view mirror contributes to space saving in the vehicle, and it is possible to perform an operation for performing a predetermined process without touching the rear-view mirror. In addition, since the rear-view mirror is near the user who is the driver, it can be used as a rear-view mirror, and it becomes easy to make a gesture in front of the rear-view mirror, so that it is not necessary to place an electronic device near the user in a narrow car. .. As the rear-view mirror, the rear-view mirror provided by default in the automobile may be converted into an electronic device as it is, or may be an external rear-view mirror.

Further, it is preferable that the housing provided with the gesture detecting means as the means 26 is provided with collision mitigation means for reducing the collision of the recognition object with the housing at the time of the gesture.
In this way, it is possible to reduce the collision of the recognition object with the housing during the gesture. As the collision mitigation means, for example, a collision prevention means which is a means for preventing a collision, or a shock absorbing means which is a means for absorbing an impact when a recognition object collides with a housing at the time of a collision. It is preferable that the configuration includes at least one of the above.
For example, at least a part of the ridge angle portion or the protruding corner portion of the housing provided with the gesture detecting means for recognizing the gesture may be formed in a chamfered shape.
In this way, an object that makes a gesture by forming a chamfered ridge or corner protruding outward, for example, even if the user's hand accidentally hits the housing, the hand side does not hurt and the housing side is also damaged. It becomes difficult. When it is formed in a chamfered shape, it is preferable to make it a curved surface without discontinuity as much as possible. Along with this (or alone), a material having a cushioning effect (for example, elastic synthetic rubber) may be used to surround the periphery of the housing. In particular, for example, if the configuration includes the configuration of the means 1 and the configuration of the means 28, it is possible to know from the sound that the gesture is being recognized, and the recognition object collides with the housing during the gesture recognition. Can be reduced. For example, making a sound during gesture recognition may make it easier to make a gesture without looking at the housing provided with the gesture detection unit, and at that time, there is a possibility that a recognition object or the like may hit the housing. However, in this way, such a risk can be reduced.
Further, as the means 27, it is preferable to provide a portion where the protective member is removed in at least a part of the gesture detection direction of the housing provided with the gesture detection means for recognizing the gesture.
As the protective member, for example, a transparent thin film made of plastic made of polyethylene or the like is preferable, but the user often uses the protective member without peeling it off so as not to damage the device. .. However, after a long period of use, the adhesiveness of the protective member to the device side may decrease and the protective member may be partially peeled off. At that time, the peeled protective member may shake within the detection range of the gesture detecting means and behave as if it were mistaken for a gesture. This can cause malfunctions. Therefore, at the time of shipment, for example, by removing the part of the protective member that is likely to come off in advance, or by removing the part that may enter the detection range of the gesture detecting means if the protective member is peeled off, the peeled protective member is a gesture of the user. It doesn't get in the way, and it doesn't bother the user to remove the peeled part. Further, the protective member may be a protective member for transporting a housing having a gesture detecting means. In particular, the electronic information system may be provided with a member to be watched by the user at the time of use, and the protective member may be a protective member of the member to be watched at the time of use. For example, the member to be watched at the time of use may be, for example, a mirror or a display unit. This is because it is highly necessary to protect the members that are closely watched during use, especially during transportation.
Further, the protective member may be provided across the gesture detection direction of the gesture detection means and the display unit, and a portion from which the protective member has been removed may be provided in at least a part of the gesture detection direction. Further, in a configuration in which the gesture detection direction of the gesture detection means is located near the end of the protective member instead of the center, it is preferable to provide a portion where the protective member is removed for at least a part of the gesture detection direction. This is because the protective member is particularly easy to peel off on the side closer to the end of the protective member, and the peeled protective member is likely to interfere with the user's gesture.

Further, as the means 28, it is preferable to provide a shielding means for making it difficult to visually recognize the gesture detecting means from the outside for at least a part of the housing provided with the gesture detecting means for recognizing the gesture.
It is good in design that the gesture detecting means housed in the housing is not easily visible from the outside. However, since the gesture detecting means may have a window-shaped opening in the housing for performing the detection operation, the gesture detecting means inside the housing may be visually observed from the outside. Therefore, by providing the housing with a shielding means for making it difficult to see the gesture detecting means, the user cannot see the gesture detecting means and feels a good impression on the housing design. The shielding means must not interfere with the detection of the gesture detecting means, for example, when the gesture detecting means detects by an optical means such as infrared rays, infrared rays are transmitted in a detectable manner and visible light is transmitted, for example. It is preferable to arrange a transmitter having a property of not transmitting by reflecting or absorbing. In particular, for example, if the configuration includes the configuration of the means 1 and the like and the configuration of the means 28, a sound is produced during gesture recognition, so that the user may find the gesture recognition means more easily than before, and each time a sound is produced. There is a possibility of looking at the housing, and the possibility that the gesture recognition means is annoying is increased, but this possibility can be reduced.
Further, as the means 29, it is preferable that the housing is provided with a gesture detecting means for recognizing a gesture and a distance shortening means for reducing the distance to an object existing in the gesture detecting direction of the gesture detecting means to a predetermined value or less.
For example, a wall surface or a glass surface of the housing exists as an object in the gesture detection direction of the gesture detecting means in the housing. A detection medium such as infrared rays or ultrasonic waves is output from the gesture detecting means, but the distance to the object may hinder the detection. Therefore, such a problem can be prevented by providing the distance shortening means.

Further, as the means 30, when there is a shield that hinders the gesture detection in the detection area of the gesture detecting means that recognizes the gesture, the gesture detecting means does not detect the shield or detects detection data. It is good to detect gestures by the user without using it.
As a result, the operation of the shield is not mistaken for the user's active gesture, and the user can operate the shield without feeling any operational stress even when the shield is placed.
For example, when an electronic information system is arranged in a rearview mirror near the windshield of a vehicle as a system for a vehicle, the sun visor is detected as a gesture when the user operates the sun visor as a shield near the windshield. Even if the user operates to enter the detection area of the means, the user can make a gesture.
Further, as the means 31, the gesture detecting means for recognizing the gesture does not detect the shield based on the fact that the shield is stopped and exists in the detection area for a predetermined time, or the user does not use the detection data. It is good to detect gestures.
This is a gesture detection method when a specific obstruction is present, and is a condition for determining that the gesture is not a gesture for performing a predetermined process by being stopped for a predetermined time in the detection area. Is. Since the user only needs to arrange the shield so as to stop it for a predetermined time, it is possible to operate by gesture without feeling the stress of operation. Especially in vehicles, in principle, the objects inside the vehicle are fixed in order to ensure safety while driving. Therefore, if there is an object that may enter the gesture recognition area, that object is likely to be fixed after changing its position. For example, in the case of a rear-view mirror type device provided with gesture detecting means, the position of the sun visor of the vehicle adjacent to the rear-view mirror can be adjusted, but it is fixed after the adjustment. In this way, even if an object is moved in the vehicle, it is usually in a stationary state at a certain position. Based on such knowledge, it is desirable to have this configuration especially in the equipment installed in the vehicle.
Further, as the means 32, the control means may be controlled so as not to recognize the gesture when the shield is detected closer than the predetermined distance to the gesture detecting means.
As described above, since the gesture area cannot be secured due to the presence of the shield and the gesture itself may become impossible, it is possible to prevent the malfunction by not recognizing the gesture. In addition, by arranging a shield in an area where the user cannot input gestures, it is possible to positively stop the gesture input at the user's will.
Further, as the means 33, the electronic information system may be an electronic device mounted on a vehicle. This is because the electronic devices mounted on the vehicle are often operated while driving, and it is advantageous to execute a predetermined process in relation to the sound by gestures.
From the point of view of simple operation, it is preferable not to provide any means other than the gesture detection means as the operation input means from the user to the device.
Further, it is preferable to reduce the area of the front surface of the device (particularly, the surface of the device having a means for the user to see such as having a display means or a mirror) so that no other operation input means is provided. As a result, functions other than operation input can be exhibited.
Further, as the means 34, it is preferable to display on the housing so that the user can recognize the directions of a plurality of different gestures that can be detected by the gesture detecting means.
This allows the user to easily understand the direction of the gesture. The display may be performed by printing, for example, or may be three-dimensionally modeled at the time of plastic molding.
Further, the means 35 may be a program for realizing the function of the control means in the electronic information system on the computer.

According to the present invention, it is possible to acquire information as a result of a predetermined process without directly contacting the device. In addition, since the gesture is accompanied by a sound, it is possible to understand the content of a predetermined process by the sound.

Hereinafter, embodiments of the radar detection device 10, which is an electronic device embodying the electronic information system of the present invention, will be described with reference to the drawings.
FIG. 1 is a perspective view of a radar detection device 10 that also serves as a rear-view mirror for a vehicle according to the present embodiment. In the radar detection device 10, a thin plate-shaped rectangular parallelepiped housing 13 is formed from a main body case 11 and a front plate 12 attached to the front surface of the main body case 11. The four ridge corners 13a of the housing 13 are chamfered in a curved shape (so-called rounded shape), and the front corner peripheral edge 13b, which is the protruding corner of the front plate 12, is also chamfered over the entire circumference. It is configured. A pair of left and right fixing clamp portions 14 are formed on the back surface of the main body case 11 at predetermined intervals. A power switch (not shown) is arranged at a lower position of the main body case 11, and a slot 16 for inserting a microSD card is formed at a side position of the main body case 11. As shown in FIG. 2, the control board 17 is arranged in the main body case 11. The control board 17 has a horizontally long outer shape that substantially corresponds to the front shape of the main body case 11. In the present embodiment, the control board 17 is composed of one board, but may be composed of two or more boards.

As shown in FIGS. 2 and 3, a speaker device 20 as a notification means is arranged in the recessed space 19 of the main body case 11. The speaker device 20 is connected to the control board 17, and a predetermined sound (voice) is output by control by the control unit 35 described later. The speaker device 20 is fitted in a storage space 21 formed in the main body case 11, and is attached so that the oscillation surface 20a (the surface on which sound is output) of the vibrator faces the back surface of the main body case 11. There is. A horn 23 extending downward is connected to the storage space 21, and the sound outlet 25 formed at the lower end of the horn 23 is exposed at a position adjacent to the power switch, that is, at a position below the center of the main body case 11. .. The horn 23 creates a sound transmission space in which the passage is completely surrounded. Therefore, the sound (voice) output toward the main body case 11 is reflected on the wall surface of the main body case 11, amplified in the horn 23, and reaches the outside from the sound outlet 25. Since the radar detection device 10 is attached to the rear-view mirror installed in the vehicle by default, the sound outlet 25 is located below the housing 13 so that it is close to the driver's ear and the sound is amplified. It's very easy to hear for.
As shown in FIG. 2, a sensor board 28 on which a gesture sensor 27 as a gesture detection means is mounted is connected as a separate body on the control board 17 via a BtoB connector (not shown). The gesture sensor 27 as the gesture detecting means has the control board 17 so that the distance between the front surface of the sensor and the back surface of the mirror portion 30 on the front plate 12 side is within a predetermined range (0.7 mm or less in this embodiment). The total thickness of the BtoB connector, the sensor substrate 28 and the gesture sensor 27 is taken into consideration.

A mirror portion 30 is arranged on the front surface of the front plate 12. The mirror portion 30 is formed by forming a reflective film on the front surface of a transparent glass substrate by thin-film deposition (chromium vapor deposition in the present embodiment) and forming black light-shielding printing on the back surface. The radar detection device 10 is attached to the rearview mirror provided in the vehicle by the fixing clamp portion 14, and at that time, the background is transferred to the mirror portion 30 so that the driver can check the rear view. A first window portion 31 and a second window portion 32 are formed on a part of the front plate 12 and the mirror portion 30 adjacent to each other toward the right end when viewed from the front. The first window portion 31 has a rectangular shape according to the outer shape of the display panel 18, and the second window portion 32 is configured to be smaller than the first window portion 31 according to the size of the gesture sensor 27 and has rounded corners. It has a rectangular shape. The first and second window portions 31 and 32 are regions in which only the reflective film is formed on the surface of the substrate without the above-mentioned light-shielding printing. Therefore, light can be transmitted inside and outside the housing 13 at the positions of the first and second window portions 31 and 32. The display panel 18 is arranged facing the first window portion 31, and the gesture sensor 27 is arranged facing the second window portion 32. The second window portion 32 serves as a passage for projecting and receiving light when infrared rays emitted from the gesture sensor 27 are reflected by the object and returned. The shapes and positions of the windows 31 and 32 can be changed as appropriate.
In the mirror portion 30, a mark 33 is formed around the second window portion 32 to indicate the gesture direction and to appeal to the user the position where the gesture is to be performed. The marks 33 are arranged on all four sides, up, down, left, and right so as to surround the second window portion 32, and have a mountain-shaped polygonal line shape bent so as to be convex outward, and the four marks 33 are vertically long as a whole. It is arranged in an orderly manner that resembles a rhombus. The mark 33 is a transparent portion that is not printed (however, the reflective film on the front surface is covered) by visually cutting out a part of the light-shielding printing on the back surface of the mirror portion 30. Since the front plate 12 is arranged at a slight distance from the mirror portion 30 near the second window portion 32 of the mirror portion 30, when the mark 33 is visually observed from the front of the mirror portion 30, it is behind the gap of the mark 33. The front plate 12 is visually recognized at a distance, and the mark 33 is recognized by the user with a three-dimensional effect, and is more noticeable than simple printing.

Next, the electrical configuration inside the main body 11 of the radar detection device 10 will be described based on the block diagram of FIG. Although the configuration not directly related to the present invention is omitted, for example, the same configuration as the conventional one may be adopted.
The control unit 35 as a control means is composed of a CPU, a memory such as a ROM and RAM connected to the CPU, various peripheral circuits, an interface, and the like. The display panel 18, the speaker device 20, the gesture sensor 27, the GPS receiver 37, the microwave receiver 38, the wireless receiver 39, the microSD card reader 40, and the like are connected to the control unit 35, respectively.
In the ROM of the control unit 35, there is a GPS information processing program that processes GPS information received by the GPS receiver 37, a microwave judgment program that judges microwaves (radar waves) received by the microwave detector 38, and radio. A radio wave determination program that determines the radio wave received by the receiver 39, a gesture determination program that determines the passive gesture by the gesture sensor 27, and a sound corresponding to the gesture detection result (recognition result) are output from the speaker device 20. A processing mode transition program based on gestures for shifting to a predetermined processing mode according to the judgment result of the gesture, a standby screen display program for displaying a predetermined standby screen on the display unit 17, an OS (Operation System), etc. Various programs are stored.

The control unit 35 executes each function such as a GPS alarm function, a radar wave alarm function, and a wireless alarm function, which are the basic functions of the radar detection device 10. Further, the control unit 35 outputs a sound according to the detection (recognition) of the gesture within the detection range of the object such as the hand held by the user held by the gesture sensor 27 as the object or an object held in the hand. Control is performed and the following processing is executed. As a gesture, in the present embodiment, a hand, an object, or the like is linearly moved from right to left, from left to right, from bottom to top, or from top to bottom so as to cross the front surface of the gesture sensor 27. The gesture to make it is recognized. In addition, a gesture of stopping for a predetermined time within a predetermined detection range (that is, a predetermined detection state) of the gesture sensor 27 is recognized.
As a process controlled by the control unit 35 as a result of recognizing the gesture of the gesture sensor 27 in the present embodiment, 1) change the volume, 2) change the standby screen, 3) change the setting screen, and 4) set from the standby screen. Transition to screen 5) Transition from the setting screen to the standby screen is executed respectively.

The gesture sensor 27 in the present embodiment is a known gesture sensor that detects two gestures, an approaching state and a moving state of an object (also serves as a proximity sensor to detect the approaching state). As a specific configuration, the gesture sensor 27 is equipped with an infrared light emitting LED and four photo sensors, and each photo sensor detects the light emitted from the infrared light emitting LED that hits an object and is reflected, and each photo sensor detects a change in the amount of light. It is acquired as a numerical value for each photosensor, and the distance to the object and the moving direction of the object are calculated based on a predetermined calculation formula using these numerical values as parameters. The distance to the object can be calculated as the sum of the numerical values of the four photosensors, and the moving direction of the object can be calculated by acquiring the difference between the numerical values of the photosensors acquired at different timings. It is possible to obtain the distance to the object and the moving direction of the object within the range of the detection capability of the gesture sensor 27, but here, a predetermined spatial area is set around the gesture sensor 27 as follows ( (Actually, it is judged by the numerical value of the sensor) Sound output control and predetermined processing are executed with reference to this area.

As shown in FIG. 5, the coordinates of z_th (_th represents a threshold value) equidistant from the gesture sensor 27 are set with reference to the virtual plane p in which the gesture sensor 27 exists. The equidistant means a distance at which it can be determined that the light amount data (detection value) detected by the gesture sensor 27 is equivalent. This z_th is a reference when outputting sound in the present embodiment. Hereinafter, the hemispherical space region surrounded by z_th is referred to as the sound output reference region Z.
Further, a region surrounded by a vertically inverted quadrangular pyramid within the sound output reference region Z is obtained. The area surrounded by the quadrangular pyramid is the four corners of the upper base that exist on z_th, which is the same distance from the plane p, and the four corners of the lower base that are the intersections with the plane p near the gesture sensor 27. It is a region surrounded by four line segments E1 to E4 connected to each other. Let the coordinates on each line segment be (+ x_th, + y_th) (+ x_th, -y_th) (-x_th, + y_th) (-x_th, -y_th). The moving direction of the object is detected based on the coordinates in the x-direction and the y-direction calculated in the space inside the quadrangular pyramid. This is a region set in order to easily determine the passage of the origin of the object and calculate the moving direction of the object when passing through the origin with the position of the gesture sensor 27 as the origin. Hereinafter, the area surrounded by the quadrangular pyramid is referred to as a movement direction determination area Q. In the present embodiment, the longitudinal direction of the housing 13 is defined as the x-axis direction, and the direction orthogonal to this is defined as the y-axis direction.
Further, since it is an arbitrarily set area, the distance of z_th can be appropriately changed within the detection capability of the gesture sensor 27. In this embodiment, the z_th distance can be changed to 100 mm, 60 mm, and 40 mm. As the distance of z_th changes, the size of the movement direction determination region Q existing inside the z_th distance also changes. Further, the shape imaged by the movement direction determination area Q (that is, the area in which the movement direction is determined and associated with a predetermined process) is not limited to the above and can be changed. For example, the moving direction determination area Q may be made to coincide with the sound output reference area Z.

In the electrical configuration as described above, an example of a specific process executed by the control unit 35 based on the result of detecting the object by the gesture sensor 27 will be described below.
First, the sound output control executed by the control unit 35 based on the detected value of the gesture sensor 27 will be described in relation to the object in some specific gestures. Here, a gesture that can determine the "predetermined process" described later will be described as an example, but since the movement of the object is not simple, there may be gestures other than the following gestures.
Further, as the user's recognition, there is a case where the gesture is recognized before the object enters the sound output reference area Z, and the gesture is recognized even after the object leaves the sound output reference area Z. In terms of recognizing gestures for outputting sound, entering the sound output reference area Z is considered to be the start of an objective gesture. Similarly, when the object leaves the sound output reference region Z, it is considered that the gesture ends. In addition, if the gesture recognition fails (when it is not determined to be a predetermined gesture), no sound is produced, so that the sound is also recognized as the movement of the object as a gesture. be.

(1) The first movement of the object during the gesture (No. 1)
This is the stage where the object approaches the gesture sensor 27 direction from a distance and enters the sound output reference region Z. Basically, this course always occurs as sound output control. When the control unit 35 reads the detected value of the gesture sensor 27 and determines that the object (“hand” in FIG. 6) exists in the sound output reference area Z (a certain value is set as a threshold value and exceeds it). Or when it is lower than that), that is, when it is determined that the gesture exists at the position shown by A in FIG. 6, the sound of the first scale (here, “re”) is output from the speaker device 20. The control unit 35 reads the detected value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and when it is determined that the gesture sensor 27 is within the sound output reference region Z, the output of the “re” sound is uninterrupted. To continue.
On the other hand, when the object leaves the sound output reference area Z without entering the moving direction determination area Q from the sound output reference area Z, the control unit 35 outputs the sound based on the detected value of the gesture. To stop. That is, as an assumed case, for example, when an object accidentally approaches the gesture sensor 27 and once enters the sound output reference area Z, but inverts and leaves the sound output reference area Z. Is. In that case, the "predetermined process" described later is not selected.

(2) The first movement of the object during the gesture (No. 2)
This is a state in which the gesture further enters and passes in front of the gesture sensor 27. When the control unit 35 reads the detected value of the gesture sensor 27 and determines that the object passes through the sound output reference region Z and exists in the movement direction determination region Q (when it exceeds or falls below a certain threshold value). That is, when it is determined that the gesture exists at the position shown by B in FIG. 6, it is preferable that the second scale different from (1) (the second scale is higher than the first scale, and here. Then, the sound of "fa #") is output from the speaker device 20. At this determination timing, the control unit 35 stops the "re" sound. In this way, the scale is changed and output in a state where the user can recognize that the sound has changed continuously.
The control unit 35 reads the detected value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and when it is determined that the gesture sensor 27 is within the moving direction determination area Q, the sound of “Fa #” is heard without interruption. Continue output.
Here, the control unit 35 determines that the object in the movement direction determination area Q "a. When the object crosses the front surface of the gesture sensor 27 and leaves the movement direction determination area Q" and "b. The movement direction determination area Q without crossing". Execute different voice control in "When leaving from". a. In the case of, the process proceeds to (3) below. On the other hand, b. In the case of, that is, as a assumed case, for example, an object accidentally approaches the gesture sensor 27, enters the moving direction determination region Q within a very short time, reverses, passes through the sound output reference region Z, and leaves the outside. In this case, the determination in (1) above occurs, so that the control unit 35 changes the sound from "fa #" to "re". In that case, the "predetermined process" described later is not selected.

(3) The first movement of the object during the gesture (3)
It is in a state of gradually moving away from the gesture sensor 27. The control unit 35 reads the detected value of the gesture sensor 27 and reads the above a. When it is determined that the condition is satisfied and the object exists in the sound output reference region Z (when a certain value is set as a threshold value and exceeds or falls below it), that is, the position shown by C in FIG. If it is judged that the gesture exists in, the third scale is different from (1) and (2) ((The third scale should be higher than the second scale, here "la"). The sound of is output from the speaker device 20. At this determination timing, the control unit 35 stops the sound of “Fa #”. The control unit 35 reads the detected value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and when it is determined that the value is within the sound output reference area Z, the sound of “la” is uninterrupted. Continue to output.

(4) The first movement of the object during the gesture (4)
It is a state in which the sound output reference region Z is out of the sound output reference region Z after passing the front surface of the gesture sensor 27. The control unit 35 reads the detected value of the gesture sensor 27 and reads the above a. When it is determined that the condition is satisfied and the object is separated from the sound output reference region Z (when a certain value is set as a threshold value and exceeds or falls below it), that is, at the position shown by D in FIG. When it is determined that the gesture exists, the sound of the fourth scale different from (1), (2), and (3) is output from the speaker device 20. Here, the output "sound of the fourth scale" differs depending on the moving direction of the object. This sound is a recognition-completed sound, and the frequency between the recognition-completed sound and the sound being recognized before that is set to be larger than the frequency between the sounds that change during recognition. It is also desirable that the length of the sound is shorter than the length of the sound emitted during recognition. This is determined by the moving direction in the moving direction determination area Q in (2) above. In the present embodiment, four movement directions of "lower to upper", "upper to lower", "left to right", and "right to left" are prepared as the movement directions of the object, and sound and sound are provided for each of them. A "predetermined process" described later is associated with it. That is, the first gesture is recognized as a gesture different for each direction. When the control unit 35 determines that the movement in the movement direction determination area Q is "from lower to upper", the sound having the highest pitch among the sounds output during recognition (that is, in the present embodiment, the above-mentioned first sound). "So" is output as a recognition confirmation sound (for example, activation processing confirmation sound) which is a sound in a higher range than "la" of the third scale and is a short sound of "pip". Similarly, when it is determined that the movement is "from top to bottom", "do" is output. Similarly, when it is determined that the movement is "from left to right", "re" is output. This "re" is one octave higher than the "re" of the first scale described above. Similarly, if it is determined that the movement is "from right to left", "mi" is output. These sounds correspond to "processing different depending on the moving direction of the object" executed by the control unit 35, which will be described later. Then, when the sound is separated from D in FIG. 6 (moves to the right in the figure), the control unit 35 makes a sound based on the detected value of the gesture sensor 27 to be detected (that is, when a certain numerical value is set as a threshold value and exceeds or falls below it). Stop the output.
(5) The first movement of the object during the gesture (4th variation)
After passing the front surface of the gesture sensor 27, it goes out of the sound output reference region Z and stops in the vicinity thereof. The control unit 35 reads the detected value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and the numerical value that the object is separated from the sound output reference area Z and stays in the vicinity of the sound output reference area Z. If it is determined that the gesture is, and if a predetermined time (for example, 0.3 seconds) or more has passed, that is, if it is determined that the gesture has been present for a long time at the position shown by D in FIG. 6, it is intermittent at a predetermined timing. The sound corresponding to the four movement directions, that is, one of the same "so", "do", "re", and "mi" as the above-mentioned recognition confirmation sound is output. This intermittent sound corresponds to the so-called "long press mode" in the "predetermined process" executed by the control unit 35, which will be described later. Then, when separated from D in FIG. 6, the control unit 35 stops the sound output based on the detected value of the gesture sensor 27 to be detected (that is, when a certain numerical value is set as a threshold value and exceeds or falls below it), as in (4). Let me.

With respect to the above four moving directions, the moving direction of the object does not always move exactly horizontally or vertically. For example, when an object moves in an oblique direction, it may be taken either horizontally or vertically. The control unit 35 compares the horizontal component and the vertical component based on the obtained numerical values, selects whichever is greater, and selects whether the movement is in the horizontal direction or the vertical direction.
The moving direction is determined when the object separates from the sound output reference region Z (goes out of z_th). That is, a. At the stage of, the predetermined process is only selected and is not yet determined, but is determined based on a certain detection value detected by the gesture sensor 27 at a later timing. Predetermined processing may be canceled or changed depending on the movement of the object at the position where the "la" sound of (3) is output.

(6) Second movement of the object during the gesture As shown in FIG. 7, the control unit 35 reads the detected value of the gesture sensor 27 and the object is in the sound output reference area Z (including the movement direction determination area Q). If it is determined that the value exists in, and the object is stopped for a predetermined time (for example, 2 seconds) or longer, a predetermined pitch with a "crisp" tone that is different from any of the above sounds. Sound is intermittently output from the speaker device 20. The stopped state is determined based on the fact that the detected value of the gesture sensor 27 does not fluctuate at all or fluctuates only within a narrow numerical range.
Further, the control unit 35 reads the detected value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and stops the sound output when the stopped object moves. After the stopped object moves, the audio output control is performed according to the positions of the objects (1) to (4) above.
If the object enters the sound output reference area Z as a premise of the audio output processing based on this stop and the above conditions (1) and (2) are satisfied, then (1) and (1) and ( Audio output according to 2) is also executed.

When a specific gesture is performed in the above gesture, a predetermined process is selected together with the sound, and the predetermined process is further confirmed. Next, those predetermined processes executed by the control unit 35 will be described in conjunction with the actual gestures and the sounds output in association with the gestures. In the initial setting, the distance of z_th of the sound output reference region Z is set to 10 cm. Further, when the object crosses the movement direction determination area Q very quickly, the difference between the detected values of the gesture sensor 27 cannot be acquired and an error occurs. That is, the moving direction becomes indefinite, and as a result, a predetermined process cannot be determined. Therefore, in the following, it is assumed that the moving direction is determined by moving the object at an appropriate speed, and the predetermined processing is determined accordingly.
A. About changing the volume (from bottom to top)
As shown in FIG. 8, radar detection is performed by maintaining a distance of, for example, 7 cm in front of the front plate 12 of the radar detection device 10 and passing the hand as an object from the lower position of the radar detection device 10 to the front of the gesture sensor 27. Make a gesture of sliding once to the position where the device 10 is pulled out upward. At this time, the control unit 35 determines that the object has made a gesture of sliding once from the bottom to the top in front of the gesture sensor 27, and raises the volume by one step from the current state. Then, in conjunction with this gesture, the control unit 35 outputs sound from the speaker device 20 in the order of “re” → “fa #” → “la” → “so” (the first object in the above series of gestures). Equivalent to 1 movement).
On the other hand, as shown in FIG. 9, the hand is passed from the lower position of the radar detection device 10 to the front surface of the gesture sensor 27 and then stopped near the upper edge of the housing 13. This position corresponds to the outer position of the sound output reference area Z close to the sound output reference area Z. In FIG. 8, the object is largely separated from the sound output reference area Z, but in FIG. 9, although it is outside the set sound output reference area Z, the object exists in the sound output reference area Z as a detected value. The difference from the case is very small.
When the control unit 35 detects a stop state at this position for a predetermined stop time (for example, 0.3 seconds) or longer, it determines that it is in the so-called "long press" mode, and the control unit 35 continuously raises the volume from the current state. To control. At this time, in conjunction with this gesture (corresponding to the above "4th variation"), the control unit 35 is connected to the speaker device in the order of "re"->"fa#"->"la"->"so" intermittent sound. Sound is output from 20. The control unit 35 ends the process when the object is released from the stopped state or the volume is maximized (a state in which no further change is possible), and the intermittent sound is also stopped.

(From top to bottom)
On the contrary, as shown in FIG. 10, the gesture of sliding the hand once from the upper position of the radar detection device 10 to the position where the hand passes through the front surface of the gesture sensor 27 and exits below the radar detection device 10 is performed. At this time, the control unit 35 determines that the object has made a gesture of sliding once from above to below in front of the gesture sensor 27, and lowers the volume by one step from the current state. At this time, in conjunction with this gesture, the control unit 35 outputs sound from the speaker device 20 in the order of “re” → “fa #” → “la” → “do” (object in the above series of gestures). Corresponds to the first move).
On the other hand, as shown in FIG. 11, after passing the hand from the upper position of the radar detection device 10 to the front surface of the gesture sensor 27, the hand is stopped near the lower edge of the housing 13. This position corresponds to the outer position of the sound output reference area Z adjacent to the sound output reference area Z. When the control unit 35 detects a stopped state at this position for a predetermined stop time (for example, 0.3 seconds) or longer, it determines that it is in a so-called "long press" mode and controls the volume to be continuously lowered from the current state. At this time, in conjunction with this gesture (corresponding to the above "4th variation"), the control unit 35 is connected to the speaker device in the order of "re"->"fa#"->"la"->"do" intermittent sound. Sound is output from 20. The control unit 35 ends the process when the object is released from the stopped state or the volume is maximized (a state in which no further change is possible), and the intermittent sound is also stopped.

B. About changing the standby screen (from left to right)
As shown in FIG. 12, the radar detects the radar by passing the hand as an object from the left position of the radar detector 10 to the front of the gesture sensor 27 while maintaining a distance of, for example, 7 cm in front of the front plate 12 of the radar detector 10. Make a gesture to slide the detector 10 to the right once to the right position. At this time, the control unit 35 determines that the object has made a gesture of sliding once from the left to the right in front of the gesture sensor 27, and displays the current standby screen on the display screen to the right. A screen display is displayed in which the next standby screen at an adjacent position, which has been hidden after being exited, is slid to be displayed on the display screen of the display panel 18. At this time, in conjunction with this gesture, the control unit 35 outputs sound from the speaker device 20 in the order of “re” → “fa #” → “la” → “re” one octave higher (during the above series of gestures). Corresponds to the first movement of the object in).
The standby screen of this embodiment is looped in the order of calendar → clock → speed → eco-drive mode → positioning information → rotation of all standby screens → display off → radar scope → drive mode ... 8 times from the current state. It is supposed to return to the original standby screen mode by moving.
On the other hand, as shown in FIG. 13, after passing the hand from the left position of the radar detection device 10 to the front surface of the gesture sensor 27, the hand is stopped near the right edge of the housing 13. This position corresponds to the outer position of the sound output reference area Z adjacent to the sound output reference area Z. When the control unit 35 detects a stop state at this position for a predetermined stop time (for example, 0.3 seconds) or longer, it determines that it is in the so-called "long press" mode and changes the looped standby screen to the display screen one after another. Let me.
At this time, in conjunction with this gesture (corresponding to the above "4th variation"), the control unit 35 is connected to the speaker device in the order of "re"->"fa#"->"la"->"re" intermittent sound. Sound is output from 20. The control unit 35 ends the process when the stopped state of the object is released, and also stops the intermittent sound.

(From right to left)
On the contrary, as shown in FIG. 14, the gesture of sliding the hand once from the right position of the radar detection device 10 to the position where the hand is pulled out to the left of the radar detection device 10 is performed. At this time, the control unit 35 determines that the object has made a gesture of sliding once from the left to the right in front of the gesture sensor 27, and displays the current standby screen on the display screen to the left. A screen display is displayed in which the next standby screen at an adjacent position, which has been hidden after being exited, is slid to be displayed on the display screen of the display panel 18. At this time, in conjunction with this gesture, the control unit 35 outputs sound from the speaker device 20 in the order of “re” → “fa #” → “la” → “mi” (object in the above series of gestures). Corresponds to the first move).
On the other hand, as shown in FIG. 15, after passing the hand from the right position of the radar detection device 10 to the front surface of the gesture sensor 27, the display panel 18 stops the hand near the left side. This position corresponds to the outer position of the sound output reference area Z adjacent to the sound output reference area Z. As a result, the control unit 35 determines that the mode is the so-called "long press" mode, and changes the looped standby screen to the display screen one after another.
At this time, in conjunction with this gesture (corresponding to the above "4th variation"), the control unit 35 moves the speaker device in the order of "re"->"fa#"->"la"->"mi" intermittent sound. Sound is output from 20. The control unit 35 ends the process when the stopped state of the object is released, and also stops the intermittent sound.

C. Transition to the setting screen As shown in FIG. 16, a gesture is made to maintain and stop a distance of, for example, 9 cm at a position facing the gesture sensor 27 on the front surface of the front plate 12 of the radar detection device 10. At this time, the control unit 35 determines that the object has a gesture to stop for a predetermined time (for example, 2 seconds) or more in front of the gesture sensor 27, and the standby screen is displayed on the display screen of the display panel 18 by default. Move from the state to the setting screen.
The setting screen of this embodiment is the transition initial screen. Starting from MAP → Mode (and its submenu) → Brightness (and its submenu) → Flex Dimmer (and its submenu) → Radar alarm sound (and its submenu) → Sensor confirmation sound (and its submenu) ) → Sensor reaction range (and its submenu) → Initial setting (and its submenu) → Version display → Demo mode (and its submenu) → Standby screen → ity. It is looped like MAP, and by the same operation as "B. Changing the standby screen" above, the display screen of the display panel 18 is displayed one after another from left to right or from right to left. You can change the setting menu to be displayed. Further, in the submenu, the setting menu to be displayed on the display screen of the display panel 18 can be changed one after another from the bottom to the top or from the top to the bottom by the same operation as the above "A. About changing the volume". .. Here, since the standby screen is included in the loop of the setting screen, if you want to return to the standby screen in the transition mode to this setting screen, you can make a gesture in the setting screen without turning off the power once. It is possible to execute by doing. After returning to the standby screen, the above-mentioned "B. Changing the standby screen" gesture becomes possible.
When the control unit 35 detects a stopped state at this position for a predetermined stop time (for example, 2 seconds) or longer, it intermittently makes a "crisp" sound as described in the second movement of the object during the above (6) gesture. Is output from the speaker device 20 (corresponding to the second movement of the object during the above gesture). In the gesture for changing the setting screen, a sound according to the description of the first movement of the object in the series of gestures (1) to (4) above is output.

Next, processing when some kind of obstruction that hinders the judgment of the gesture exists in the sound output reference region Z will be described.
For example, assume that the radar detection device 10 is used in a vehicle. In that case, the sun visor may be used due to the dazzling sunlight. Then, depending on the mounting position of the radar detection device 10, the sun visor may act as a shield and enter the sound output reference region Z. The following is a process for the user to perform a gesture without hindrance even if there is such a shield, and it is said that a normal gesture is recognized after offsetting (subtracting) the detected value based on the amount of light from the shield. It is a thing.

(Judgment of the presence or absence of a shield in the initial state)
First, the control unit 35 determines the following three states in the initial state without a shield.
a. It is said that some kind of obstruction (this is judged without distinguishing the object, the same applies hereinafter) has entered the sound output reference area Z, and there has been a stop for a predetermined time (120 ms) without determining a predetermined process. When judging b. When it is determined that some kind of obstruction has entered the sound output reference area Z and the gesture of "(6) Second movement of the object during the gesture" has been performed for 5 seconds or more. When it is determined that some kind of obstruction has entered the sound output reference area Z and the gesture of "(5) First movement of the object during the gesture (4th variation)" has been performed for 8 seconds or more.

Here, a. Is based on the assumption that the processing mode is not changed due to the invading shield. The setting of 120 ms corresponds to the interval because the control unit 35 calculates the offset every 120 ms. In this case, the control unit 35 calculates to offset the detection value of the gesture sensor 27 changed by the shield, and uses the state of the gesture sensor 27 after the offset as the detection reference.
In addition, b. And c. Is a state in which the display screen and volume have changed after shifting to some processing mode, and by setting a long time, the stop gesture is different from the normal gesture. In these cases, since an unintended process has been executed by the shield, the control unit 35 forcibly shifts to the standby screen set by default. Similarly, by forcibly setting the volume of the voice to the default setting, the processing that may have started due to an unintended input is canceled. And after that, a. Similarly, the control unit 35 calculates to offset the detected value of the gesture sensor 27 changed by the shield, and uses the state of the gesture sensor 27 after the offset as the detection reference.
The above is schematically shown in FIG. 17 (a).

(Judgment of the presence or absence of a shield during offset calculation)
The normal gesture recognition is executed with the offset calculation started as described above and the light amount of the obstruction is canceled. During gesture recognition, the control unit 35 always calculates the offset at a predetermined timing (120 ms) and uses the latest state of the gesture sensor 27 as a detection reference.
Here, the shield that once stayed in the sound output reference region Z may move. For example, the sun visor is swayed, the position is changed depending on the direction of the sunlight, or the sun visor is separated from the sound output reference region Z and returned to the original position. Assuming that the shield moves, the control unit 35 determines the following three states.
d. When the shield has moved but the predetermined treatment has not been decided e. When it is determined that the shield moves and the gesture of "(6) Second movement of the object during the gesture" is performed for 5 seconds or more. F. When it is determined that the shield has moved and the gesture of "(5) First movement of the object during the gesture (4th variation)" has been performed for 8 seconds or more d. For example, assumes a case where the shield in the sound output reference region Z slightly sways due to vibration. In this case, since there is no particular change in the current processing of the radar detection device 10, the control unit 35 calculates to offset the detection value of the gesture sensor 27 at a predetermined timing as described above.
e. And f. Is a state in which each is recognized as a gesture, shifts to some processing mode, and the display screen and volume have changed. In this case, the control unit 35 has the above b. And c. Similarly, the screen is forcibly shifted to the standby screen, the voice is forcibly set to the default volume, and then the detection value of the gesture sensor 27 is offset at a predetermined timing as described above.
The process executed by the control unit 35 is described in b. And c. Similar to, but different in purpose. b. And c. Then, in the initial state, it is a correspondence when a shield enters the sound output reference region Z from the outside, and it is a correspondence in a state where the offset has not been calculated yet. And f. Is a response during the calculation of offsetting the shield when the shield enters the sound output reference region Z (after the start of the offset calculation).
The above is schematically shown in FIG. 17 (b).

(When the shield is near the gesture sensor)
When the shield is placed very close to the gesture sensor 27, normal gestures cannot be performed because there are few gaps in the space. That is, the detection by the gesture sensor 27 becomes physically impossible. Therefore, assuming such a state, when the shield is placed very close to the gesture sensor 27, a process is performed so as not to recognize the gesture. Specifically, the control unit 35 always has a shield within a predetermined distance (for example, 3 cm) from the gesture sensor 27 at a predetermined timing (120 ms) during gesture recognition, and it is for a predetermined time (for example, 5 seconds). Determine if it has stopped. Then, when it is determined that there is a shield within a predetermined distance and it is stopped for a predetermined time or more, the control unit 35 cancels the detection value of the gesture sensor 27 in the calculation. That is, although the gesture is recognized by the gesture sensor 27, the gesture sensor 27 is apparently not operating as if nothing was detected (actually, the detection of the gesture sensor 27 itself is stopped). You may let me).
On the other hand, when the control unit 35 determines that the gesture sensor 27 has moved more than a predetermined distance, the calculation using the detected value of the gesture sensor 27 is restarted.

Next, the process for temporarily returning the "sensor reaction range" set by the user on the setting screen to the default state (here, the range of 10 cm) will be described. This process assumes the following cases.
If the sensor reaction range is in the default state, the range is set wider, so there is a possibility that the sensor reaction range (output reference area Z) may be touched and some processing may be executed. Therefore, it is preferable that the sensor reaction range can be set to, for example, normal (6 cm) or narrow (4 cm) by the user's setting. However, even in such a case, it is better to return to a wide range of default states in order to operate quickly depending on the situation. Here, as an example, the control unit 35 for temporarily widening the "sensor reaction range" is used to facilitate the operation of muting the alarm when some alarm is issued from the radar detection device 10. The process will be described based on the routine of FIG. The control unit 35 repeatedly executes this routine at a predetermined timing.
First, in step S10, the control unit 35 determines whether or not the alarm has been notified, and if it determines that the alarm has been notified, determines in step S11 whether or not the current sensor reaction range is set to 10 cm. Here, if it is determined that the sensor reaction range is set to 10 cm, the process ends once. In other words, it is not necessary to change the sensor reaction range.

On the other hand, when it is determined in step S11 that the current sensor reaction range is not 10 cm (that is, 6 cm or 4 cm), the sensor reaction range is controlled to be 10 cm in step S12, and the flag is set to "1" in step S13. Is set up to end the process once. This will temporarily change the sensor response range to 10 cm.
On the other hand, if it is determined in step S10 that the alarm has not been notified, it is determined in step S14 whether or not the flag is "1". Here, when the flag is "1", it means that the sensor reaction range has been once changed to 10 cm in the immediately preceding routine, so the sensor reaction range immediately before that is returned to 6 cm or 4 cm, and the flag is changed to "1". 0 ”. On the other hand, when the flag is not "1" in step S14, it means that the sensor reaction range immediately before was not changed, and the process is terminated as it is.
With such control, when the alarm is notified, the sensor reaction range is temporarily changed to a distance of 10 cm, which is easy for the user to operate, and the user can easily suppress the volume by gesture operation. On the other hand, when the alarm is completed, the sensor response range is restored, so that the user can save the trouble of setting again.

With the above configuration, the radar detection device 10 of the present embodiment has the following effects.
(1) The radar detection device 10 does not require an input unit or a touch panel composed of, for example, an electrostatic switch for actually touching and operating as in the conventional case, and can be operated by four-direction operation + approach stop operation, which is extremely difficult. The cost can be reduced and the weight can be reduced because the components such as the input unit are not required, which is particularly suitable for installing the radar detection device 10 in a vehicle having a lot of vibration.
(2) Radar detection devices Since so-called high-end machines with many various functions require detailed settings, an input unit such as a remote controller or touch panel is inevitably required. However, especially in the low-end machine, which tends to have few setting items, even if the input is made by a gesture, the operation is simple and there is no omission, so that it is most suitable for the low-end machine. It is not necessary to mount the gesture sensor 27 on the high-end machine, and even if the gesture function is provided, it is only an auxiliary input, which increases the cost. That is, it is possible to provide a device such as a radar detection device that is not provided with any means other than the gesture detection means as an operation input means from the user to the device.
(3) The radar detection device 10 also serves as a rear-view mirror, but by being able to input by gestures in this way, the switch area on the side of the mirror unit is no longer necessary as in the past, and it becomes a full-face mirror, compared to the conventional one. The mirror area will increase relatively, and the function as a room mirror will be improved for the user. In addition, since the user can operate the mirror surface without touching the mirror surface, it is less likely to be soiled by fingerprints or the like.
(4) Since the user can shift the radar detection device 10 to a desired processing mode simply by executing a predetermined gesture, it is not necessary to visually search for an input unit or the like for actually touching and inputting. It is advantageous in terms of operation. Also, if you are driving, you do not have to search for an input unit or the like, so you can concentrate on driving.
(5) For example, since the housing 13 is less likely to get dirty because it does not come into contact with the input unit or the touch panel for touching and operating, deterioration due to contact can be prevented.
(6) The user can memorize a gesture pattern that emits the same sound by repeating the gesture several times, and by executing the gesture, it becomes easy to select a desired process. At that time, the gesture pattern can be accurately memorized based on the type of sound and the output timing of a plurality of sounds.
(7) When a series of gestures includes a gesture for executing a predetermined process, a sound corresponding to the predetermined process is output, and the user understands the content of the predetermined process in relation to the sound. can do.
(8) Even if there is a shield such as a sun visor that hinders the judgment of the gesture in the sound output reference area Z, an input for operation is performed in order to execute a process for canceling this influence. It is definitely possible to input even if there is no reliable input means such as a part.
(9) Even if the sensor reaction range is set to normal (6 cm) or narrow (4 cm) in the user's settings, it is 10 cm that is temporarily easy for the user to operate when an alarm is notified. Since it is changed to the sensor reaction range of the distance, it becomes easier for the user to suppress the volume by gesture operation. On the other hand, when the alarm is completed, the sensor response range is restored, so that the user can save the trouble of setting again.
(10) Since the sound outlet 25 of the speaker device 20 is located below the housing 13, it is close to the ear when the radar detection device 10 is installed in the vehicle, and the sound is amplified in the horn 23 for the user. It's very easy to hear.
(11) The four marks 33 indicating the sensor positions indicate the gesture directions (up / down / left / right) for simultaneously executing a predetermined process, so that the user can easily understand them for the first time.

The present invention may be embodied and implemented in the following embodiments.
-In the radar detection device 10 of the above embodiment, as shown in FIG. 2, the sensor board 28 on which the gesture sensor 27 is mounted on the control board 17 is connected in a laminated manner as a separate body via a BtoB connector (not shown). Was there. However, when the gesture sensor 27 is arranged close to the back surface of the mirror portion 30 by such a connection, it is separated from the mirror portion 30 more than planned due to the thickness tolerance of the substrate and does not fit within the predetermined range. In some cases.
Therefore, when arranging the gesture sensor, it is preferable to have a configuration as shown in FIG. FIG. 19 is a partially enlarged cross-sectional view of the stationary radar detector 50. The radar detection device 50 includes a main body case 51 and a front plate 52 to form a housing 53. A transparent glass cover 54 is arranged on the front surface of the front plate 52. The sensor substrate 56 on which the gesture sensor 55 is mounted is fixed to the stud 57 formed on the front plate 52 by a screw 58. The sensor board 56 is connected to the main board 59 by a flexible cable 60.
In this way, the sensor substrate 56 is independently fixed directly to the stud 57 on the front plate 52 side, and the distance to the mirror portion 30 is shortened without interposing other members in between, and the gesture sensor 55 is accurately covered 54. It is possible to place it in a position close to. In short, since the sensor substrate 56 may be fixed independently to the front plate 52 side, it may be fixed by a fixing means other than the screw 58, for example, a means such as a clip. The installation mechanism of the gesture sensor of the stationary radar detection device 50 may be applied to the configuration of the radar detection device 10.

-Various sounds are output depending on the position of the object in the gesture. At this time, the gesture outputs several sounds. The whole can be considered as one gesture, and the gesture corresponding to one sound is used. It can be thought of as a gesture. That is, for example, the following first gesture may be considered as a gesture starting from the first and ending with the fourth, or the "first gesture (second)" alone may be considered as a single gesture having a start and an end. ..
-In addition to the above gestures, for example, a gesture in which the object diagonally crosses the front surface of the gesture sensor 27 or a gesture in which the object draws a circle may be adopted. Further, for example, a gesture may be used in which the object is made to face the gesture sensor 27 and approached from a separated position (or vice versa).
-Since the second window portion 32 of the mirror portion 30 transmits visible light, the gesture sensor 27 can be visually recognized. However, it is preferable to reflect or absorb light rays in the visible light region so as not to show the gesture sensor 27, and to arrange a transmission film having a transmission characteristic that allows only infrared rays to pass through.
-The shapes and positions of the first and second window portions 31 and 32 can be changed as appropriate.
-As other processes executed by the control unit 35 illustrated in the above embodiment, for example, as processes related to sound, output and stop of sound (voice), change of sound quality (timbre), change of number of sounds. , The sound pattern (for example, melody) may be changed, the guidance voice may be changed, and the like may be set by gestures.
-In the above embodiment, the movement direction of the hand gesture is set in four directions of up, down, left, and right, but the movement direction may be prepared in a pattern other than these four directions.
-The sound in the above gesture is an example, and sounds of other pitches may be used. Also, in the above, the pitch was set so that the object gradually became higher as it crossed the sensor reaction range, but the sound output as the object moved became higher as if there was a melody. It may be set in a pattern that becomes lower or lower.
-In the above embodiment, when the sensor reaction range is set to, for example, normal (6 cm) or narrow (4 cm) by the user's setting, a distance of 10 cm that is temporarily easy for the user to operate when an alarm is notified. Although it was changed to the sensor reaction range of, such a process may be executed except in the case of alarm notification. For example, it is a case of time notification, accident information notification, and the like. Further, in the above, the sensor reaction range can be set to three distances, but it may be set to two or four or more. Further, after temporarily changing the sensor reaction range to a distance of 10 cm, which is easy for the user to operate, the process was to return the sensor reaction range to normal (6 cm) or narrow (4 cm) again, but it is not necessary to return it.
-The configuration of the radar detection device 10 is an example, and may be implemented in another shape. For example, in the above, the gesture sensor 27 was arranged to the right when facing the front, but this is mainly intended for users who make gestures with the left hand in a vehicle with a right-hand drive, but with a vehicle with a left-hand drive in mind. The gesture sensor 27 may be arranged on the left side of the vehicle (that is, it may be arranged at a position where it is easy to make a gesture depending on the vehicle). Alternatively, in the embodiment in which the gesture sensor 27 is arranged to the right of the front, the mirror is rotated 180 degrees in a plane changed to the mirror and attached to the rearview mirror of the vehicle. In this case, the setting from the user or It is preferable to determine the mounting direction by a G sensor or the like and determine whether or not to rotate the gesture recognition direction by 180 degrees so as to match the determined mounting direction.
-In addition to the radar detection device, it may be applied to, for example, a navigation device (one without a radar detection function) or a drive recorder device for vehicles.
-It may be applied to various devices other than those for vehicles.
-In the detection of the gesture sensor 27, in the above, the infrared light from the infrared light emitting element is applied to the object and the change in the reflected light is captured by the light receiving element. It is also possible to use a gesture sensor of another principle such as one utilizing the change of.
-A protective sheet for protecting the mirror surface may be attached to the front surface of the mirror portion 30. In this case, the user may use it without peeling it off at the time of use. However, there is a possibility that the protective sheet may be partially peeled off due to long-term use, and the peeled protective sheet may shake within the detection range of the gesture sensor 27 and behave as if it were mistaken for a gesture. This can cause malfunctions. Therefore, as shown in FIG. 20, the protective sheet 62 can be attached only within the range separated from the second window portion 32, or the corners that are easily peeled off can be formed in a chamfered shape, resulting in malfunction or the protective sheet 62. Does not interfere with the user's gestures, and also eliminates the hassle of removing the peeled part of the user. In particular, a protective sheet may be provided on the entire surface of the mirror, and the protective sheet may be hollowed out along the second window portion 32. In this way, the entire surface of the mirror surface can be protected, and even if the user starts using the protective sheet without removing it, the possibility that the movement of the protective sheet will be recognized as a gesture can be reduced.
-It may be applied to devices other than in-vehicle devices.
The present invention is free to be implemented in a modified manner without departing from the spirit of the present invention.
