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 that can acquire information related to driving such as a navigation device mounted on a vehicle such as an automobile or a bicycle or a microwave receiver (radar detector) mounted on the automobile. In addition, there are electronic devices such as smartphones and personal computers as electronic information systems that can acquire various kinds of information used every day.
In these electronic information systems, the user can acquire information by pressing the input switch attached to the device to acquire information, or by operating the operating means by actually touching it with the hand. Like to do. Patent Documents 1 and 2 are cited as electronic information systems having such conventional input means and operation means.
The electronic device of Patent Document 1 is a drive recorder device that is attached to a windshield of a car with a double-sided tape or the like. As shown in FIG. 3, the drive recorder apparatus includes a switch unit 20, a display unit 21, and a volume dial 23.
The electronic device disclosed in Patent Document 2 is a microwave detection device that also serves as a room mirror that is attached to a room mirror that is disposed by default in an automobile. This apparatus is configured to display various information on the display panel 13 in a part of the mirror surface by touching the touch screen 16 which also serves as a mirror surface and performing an input operation.

JP 2010-105530 A JP 2012-66640 A

However, in the drive recorder apparatus disclosed in Patent Document 1, for example, the volume dial 23 as an operation means is attached to the casing as a separate part, so that the weight of parts related to the volume dial 23 is added and the weight of the apparatus increases. . The weight increase is not preferable in the case of attaching to the windshield by such an adhesive method. In addition, the number of parts increases, leading to an increase in cost. On the other hand, in the microwave detection device of Patent Document 2, the touch screen 16 that also serves as a mirror surface serves as an operation means, so that parts related to the operation are reduced and the weight is reduced. However, if the mirror surface is not actually touched, input is not performed. This is not possible, and the mirror surface may become dirty by touching.
For this reason, there has been a demand for means that can acquire information without directly touching a device while eliminating or reducing an operation member for acquiring information in an electronic information system. 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 is not the first user when he / she is notified of the success or failure of gesture recognition or when the device is informed that a predetermined process corresponding to the gesture has started. There is a problem that it is difficult to determine whether the gesture motion of the device is correct and recognizable while the gesture is being performed. . For example, there is a case where the user tries to repeat the same gesture many times, considering that the gesture state is recognizable by the device, even though the gesture state is unrecognizable by the device. For example, as a gesture state, the gesture operation is an operation that can be recognized by the device, but it is noticeable in a case where the recognition target object such as a user's hand is in a position where the device cannot be recognized, so that it cannot be recognized. There was a serious problem.
The present invention has been made to solve the above problems, and an object of the present invention is to provide an electronic information system and a program thereof capable of realizing a desired function on a device more reliably than before without directly contacting the device. Is to provide.

In order to achieve the above object, the electronic information system that performs a predetermined process based on the recognition result of the gesture by the user as the means 1 includes a control unit that performs control to output 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 cause the device to execute a desired process more reliably than in the past. Therefore, a desired function can be realized in the device more reliably than in the past. Furthermore, for example, when not recognizing a gesture, at least one of a configuration for outputting a sound different from that during recognition of a gesture and a configuration for not outputting 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 a sound is output during gesture recognition, gesture training can be performed by performing a gesture to output this sound. Furthermore, it is preferable that a sound indicating whether or not the gesture recognition is successful is output, and the sound indicating whether or not the gesture recognition is successful and the sound output during the gesture recognition are different from each other. In this way, the user can more reliably know whether or not the gesture is being recognized and whether or not the gesture has been successfully recognized. Therefore, the user can more reliably know whether or not the gesture is being recognized by sound, and performs a gesture to output a sound indicating that the gesture is being recognized. It is also possible to train a gesture so that the user can surely realize a desired function, such as practicing to practice.

Here, as “performing predetermined processing based on the recognition result of gesture”, for example, it may be configured to perform predetermined processing according to the mode of the gesture after the gesture is recognized. The gesture may be realized as input information. Here, as the “predetermined process”, for example, a configuration may be adopted in which information is provided from an electronic information system that is performed as a result of recognizing a gesture. As a more specific predetermined process, for example, as an auditory process, for example, a sound may be generated, a volume may be changed, or the like. For example, the sound may be configured to include, for example, an alarm sound or transmission of information by voice guidance such as “please be careful”, music, or the like regardless of whether or not there is a scale. In addition, for example, information may be displayed on the display screen as a visual process, the displayed information may be deleted, the displayed information may be changed, and the like. The gesture recognition result may be controlled mechanically or hydraulically and pneumatically by driving some actuator. For example, the locking device may be released or locked, or the door may be opened or closed. A configuration may be adopted in which a plurality of different gestures are recognized and different functions are realized depending on the recognized gestures. For example, it may be configured to recognize a plurality of different gestures and perform different processes depending on the recognized gestures. In particular, in a configuration that includes a function of recognizing a plurality of different gestures and performs different processing depending on the recognized gesture, a configuration that outputs different sounds during recognition of different gestures may be used. In this way, the user can understand which process is likely to be executed during gesture recognition. In particular, a configuration for outputting different sounds during recognition of different gestures may be configured 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 until the recognition is completed. Therefore, when it is recognized as a process of an incorrect gesture, it is confirmed that an unintended process is executed and an unintended function is realized as a result of being recognized as an unintended gesture, such as by stopping the gesture in the middle. Can be prevented during gestures.
“During gesture recognition” may be, for example, a part during gesture recognition, but may be a large part during gesture recognition, or may be a whole during gesture recognition. In particular, “during gesture recognition” may be during gesture recognition in gesture recognition processing. In particular, sound may be output continuously while gesture recognition is being performed in the gesture recognition process. In particular, even in a configuration in which the sound is changed during recognition, it is preferable to output continuously so that the sound is not interrupted when the sound is changed.
In this way, it can be understood that the gesture recognition has started when the sound during gesture recognition starts, and the gesture recognition has been interrupted when the sound during gesture recognition is interrupted. Therefore, the user can surely realize a desired function, and gesture training is further facilitated.
As the “electronic information system”, for example, a system that can be installed in a vehicle, carried by a user, or installed in a room and accessed by a user to acquire information is preferable. The electronic information system mounted on the vehicle may be an electronic device such as a navigation device, a radar detection device, or a drive recorder. As an electronic information system that a user carries or installs 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 sound at different timings during gesture recognition.
In this way, it is possible to more reliably grasp that the gesture is being recognized by outputting the sound not only once but a plurality of times at different timings. In particular, the “different timing” may be a timing indicating a gesture recognition process. In this way, the user can grasp the gesture recognition process from whether or not different sounds are output. For example, the “different timing” may be a timing at which a change in the position of the recognition target object is detected. In this way, the user can easily grasp by sound whether the position of the object has moved to an appropriate position. The sound output at different timings may be configured to create different sound patterns according to predetermined processing, for example. In this way, the user can easily understand and confirm the contents of the predetermined process from the sound pattern. In addition, even if the user does not actually recognize the contents of the predetermined process, it can be understood that various sound patterns are output in relation to the predetermined process, and the operation means is actually touched. Compared to the case, you can feel an operational interest that is not in the past.
Moreover, as the means 3, it is preferable that the sounds output at the different timings include different types of sounds.
Thus, by outputting different types of sounds as sounds output at a plurality of different timings, 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 tone (high and low) of the sound is different, the sound quality (tone color) is different, or different types of sounds are mixed. Even the same tone can be recognized as different types of sound by changing the sound quality. In addition, as described above, it can be understood that different types of sounds are output in relation to the predetermined process even if the user does not actually recognize the contents of the predetermined process in relation to the sound. It is possible to feel an operational interest that has not been achieved in the past as compared to the case of actually touching the operation means.
Further, as the means 4, it is preferable that the sounds output at the different timings include different types of sounds according to the difference in the approach distance with respect to the gesture detecting means for recognizing the gesture.
Thus, by generating different types of sounds according to the difference in approach distance, the user can recognize the degree of approach to the gesture detection means by sound. In addition, even if the user does not actually recognize the relationship between the sound and the degree of approach, a different type of sound is output with the gesture, which is not compared with the case of actually touching the operation means. You can feel the interest in operation. There are several types of detection devices as “gesture detection means”. For example, a gesture sensor is a detection device equipped with a gesture sensor that detects the movement of an object by applying infrared light from an infrared light emitting element to the object and capturing the change in the reflected light by the light receiving element. Instead, a detection device including a gesture sensor using ultrasonic waves, a detection device including a gesture sensor using a change in capacitance due to a gesture, and the like can be used. The approach distance may be the distance between the recognition object and the detection device of the gesture detection means. The object to be recognized can be various objects, such as a stick, but may be a part of the human body. It is especially good to have a hand.

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

Further, as means 7, it is preferable to associate a gesture pattern with an output sound.
As a result, the user can understand the contents of the predetermined process by executing a certain gesture and listening to a pattern having a sound. Further, even if the user does not actually recognize the contents of the predetermined process, it can be understood that various sound patterns are output in relation to the predetermined process. In addition, compared with the case of actually touching the operation means, it is possible to feel an unprecedented operational interest. Here, as the “sound”, for example, it is preferable to output the sound of a certain scale as a melody by one-time output or a plurality of times of output, or to output the same scale or melody in a pattern different only in sound quality. In this way, the user can easily grasp during gesture recognition which gesture pattern corresponds to which sound and which process is expected to be executed based on that sound. Accordingly, it is possible to effectively prevent a process unintended by the user from being executed as a result of the recognition of the gesture being recognized as being different from the intention of the user.
Further, as the means 8, it is preferable to output a plurality of the same sounds according to the detected distance during the recognition of the gesture regardless of the gesture pattern.
This makes it possible for the user to recognize that the user has stopped at a certain distance, for example, when a gesture for stopping is executed, by repeating the same sound, for example, the hand is shaking and the hand cannot be stopped properly due to vibration. In such a case, it is possible to recognize whether or not it has been “stopped” objectively.
Further, as the means 9, it is preferable to output different types of sounds for different predetermined processes after the recognition of the gesture in accordance with a difference in predetermined processes executed after the recognition of the gesture.
As a result, the user can understand the contents of the predetermined processing executed by listening to different sounds output as a result of executing a certain gesture. Further, even if the user does not actually recognize the contents of the predetermined process, it can be understood that various sounds are output in relation to the predetermined process. In addition, compared with the case of actually touching the operation means, it is possible to feel an unprecedented operational interest. Here, as the “sound”, for example, it is preferable to output the sound of a certain scale as a melody by one-time output or a plurality of outputs, 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 generates a sound corresponding to the distance at the time of a gesture of approaching from a distance.
Further, as the means 11, it is preferable that the control means generates a sound according to the distance at the time of the gesture of moving away.
By generating a sound according to the difference in approach distance during a gesture of approaching from a distance or a gesture of separating from a distance as described above, a user can perform a predetermined process executed by such a gesture by a sound accompanying the gesture. Can be recognized.
For example, when approaching from far away, a certain sound pattern is output and the sound volume output from the device is increased, and when moving away from far away, a sound pattern different from that is output and the sound volume is decreased. Like that.
Here, the number of sounds corresponding to the difference in approach distance may be one or plural. Moreover, different types of sounds may be included. If there are a plurality of sounds, the number of sound patterns increases, and the user can easily understand and confirm the contents of the predetermined processing from the sounds. The gesture may be a series of gestures that are approached from a distance and separated as they are.

Further, as the means 12, it is preferable that the control means generates a sound corresponding 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 generates a sound corresponding to the separation direction at the time of a gesture for separating away.
By generating a sound according to the difference in the approach direction during a gesture of approaching from a distance or a gesture of separating from a distance as described above, the user can perform a predetermined process executed by such a gesture with a sound accompanying the gesture. Can be recognized by the relationship. For example, a sound pattern is output and the sound volume is increased when approaching from far below, and a sound pattern different from that is output and sound volume is decreased when approaching from far away. Alternatively, in the case of the separation to the lower distance, a certain sound pattern is output and the light amount of the display screen is increased, and in the case of the separation to the upper distance, a different sound pattern is output and the light amount of the display screen is increased. As you make it smaller. That is, different processing is performed with each unique sound depending on the difference in gesture, and the user can recognize that the processing according to the sound has been performed by listening to the sound. Moreover, even if the user does not actually recognize the contents 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. For this reason, compared to the case of actually touching the operation means, it is possible to feel an unprecedented operational interest. The sound according to the difference in the approach distance may be one or plural as described above. Moreover, different types of sounds may be included.

Further, the means 14 may have a first space area in which a gesture by a user can be detected and control for outputting 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 that disturbs the gesture in this space area or the movement of the user's gesture. It is possible to prevent the presence of such an object. The first spatial region is generally recognized as a region that can be detected by the gesture detection means. The approach to the first space area is preferably a three-dimensional space at an equal distance from the gesture detection means.
Further, as the means 15, it is preferable that the detectable distance of the first space region can be changed.
By adopting such a configuration, for example, the first space is considered in consideration of a situation in which a member that obstructs a gesture or an object that is mistakenly recognized as a movement of a user's gesture exists. Setting according to the situation can be made such as narrowing the area or conversely widening the first spatial area so that it can be detected as easily as possible even when the user is away from the device during the gesture.
Further, as means 16, the control means expands the first space area to a relatively wide space area in a predetermined information mode, and relative to the first space area in a case other than the predetermined information mode. It is preferable to control so as to reduce to a narrow space area.
With such a configuration, it contributes to the ease of the user's gesture when trying to cope with a predetermined information mode. As the predetermined information mode, for example, a mode for performing an operation with higher urgency than in a case other than the predetermined information mode may be provided. For example, it is assumed that there is a “state in which an alarm is being notified while driving a vehicle” as the predetermined information mode. Specifically, for example, a case where an alarm indicating that some road traffic information (for example, N system) is 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 alarm notification state because the alarm to be continuously notified is no longer necessary. That is, although it is necessary information, since the user has recognized it, further information providing operation is excessive and not necessary. In this case, it is better to keep the gesture for cancellation as simple as possible because it is driving. Therefore, even if the first space area is set to a relatively narrow space area so that an operation such as holding the hand carelessly is not recognized as a gesture, the first space area is usually accompanied by an alarm notification. By making a relatively wide space area, the user can perform a gesture without reaching too far.

Further, the means 17 may have a second space area in which the movement direction of the gesture by the user can be detected and control for outputting sound is performed.
By having such a space area, for example, it is possible to recognize which direction the user's gesture comes from and from which direction, so select a different predetermined process depending on the direction It becomes possible to do. Then, the user can recognize a predetermined process in relation to the sound corresponding to the direction. Also, even if the user does not actually recognize the contents of the predetermined process in relation to different sounds, it can be understood that various sounds are output in relation to the predetermined process, Compared to touching the means, it is possible to feel an unprecedented operational interest. For example, when moving from far down to above, a certain sound pattern is output and the volume is increased, and when moving from above far away to the bottom, a different sound pattern is output and the volume is decreased. Like you do.
The moving direction with respect to the second spatial region may include not only a planar 360 degree direction but also a three-dimensional direction. This increases the variation in the direction of movement.
Further, as the means 18, it is preferable that the detectable distance of the second space region can be changed.
By adopting such a configuration, for example, in consideration of a situation in which a user has a member that obstructs a gesture or an object that is mistakenly recognized as a motion of the user's gesture, the second is considered. Since the user can make settings according to the situation, such as narrowing the space area of the, or widening the second space area so that it can be detected as much as possible even when away from the device during gestures, The user can set an optimum gesture environment for executing a predetermined process.
Further, as the means 19, it is preferable that the second space area is inside the first space area.
As a result, when a gesture is performed, the gesture is first recognized in the first space area, and when the gesture enters the second space area, it is determined from which side the approach has been made. Since the space areas are not separated but overlapped, the space area where the user makes a gesture is not unnecessarily widened, which contributes to the downsizing of the area where the gesture is made. On the other hand, if the second space area is outside the first space area, when entering the first space area, the second space area must always enter the second space area having an approaching direction. , There is a possibility that it will be in a predetermined processing mode that the user does not plan

Further, as the means 20, it is preferable to change the volume set as the predetermined processing.
This shows an example of a specific predetermined process. In other words, control is performed to output sound during gesture recognition, and the volume is changed when the gesture is recognized. This eliminates the hassle of searching for a volume for adjusting the volume and operating the user to change the volume.
As a more specific example, a gesture that moves from a certain direction to a certain direction (for example, hold your hand from the bottom to the top of the gesture detection means. The volume may be increased by a certain amount by moving the volume up or down by a gesture that moves from one direction to another (for example, holding your hand from above to below). is there.
In addition, the volume may be changed by a special gesture so that the volume is not constant. For example, by changing the speed of movement from one direction to another with a hand or the like, you can increase the volume to be changed, or temporarily stop during the movement and continuously change the volume during that time is there.

Further, as the means 21, it is preferable to suppress notification of information currently notified as the predetermined processing.
This also shows an example of a specific predetermined process. That is, while outputting the sound during the recognition of the gesture, the notification of the currently notified alarm information is suppressed when the gesture is recognized. Thereby, 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, or a display to that effect on a display screen. “Suppress notification” means to reduce the volume or silence for audio notification, and to reduce the brightness or turn off the display screen for visual notification.
For example, an alarm during driving is described as an example. For example, when an alarm indicating that some road traffic information (for example, N system) is detected from a radar detection device as an electronic device, the user is not required to continue the alarm after the user has recognized this notification. You may want to cancel the alarm notification state. In other words, it is necessary information, but because the user has recognized it, it is excessive and unnecessary. In this case, it is meaningful to suppress the alarm sound.
To illustrate more specific control, the user holds his / her hand at a detectable position (for example, the first spatial region) (not necessarily as described above) and stops at that position for a predetermined time. Make gestures that let you By recognizing this gesture, it is time to stop the currently sounding alarm sound. At this time, for example, when the detectable area set by the user is narrow, the detection may be performed by controlling the area to be temporarily wide. This is because it is preferable to use a wide range in order to operate quickly according to the situation.

Further, as the means 22, information may be displayed on a display screen as the predetermined processing.
This also shows an example of a specific predetermined process. That is, control is performed to output sound during gesture recognition, and information is displayed on the display screen when the gesture is recognized. This eliminates the trouble of the user searching for 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 processing.
This also shows an example of a specific predetermined process. In other words, control is performed to output sound during gesture recognition, and information displayed on the display screen is changed when the gesture is recognized. This eliminates the trouble of the user searching for an operation means for changing the information on the display screen and operating it to change the volume.

As the means 24, the control means displays the 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 to display the first display mode again based on the result.
This indicates control for returning to the first display mode that is the initial screen as a result of successive gestures. With such a configuration, the user can easily understand the appearance order of the display modes that can be changed by the gesture based on the appearance order of the first display mode. This is advantageous when the first display mode has many setting screens.
Further, as the means 25, the vehicle-mounted electronic device may also serve as a rearview mirror, and the user's gesture may be performed on the front face of the rearview mirror.
This is because mounting the vehicle-mounted electronic device on the rearview mirror contributes to space saving in the vehicle, and an operation for performing a predetermined process without touching the rearview mirror is possible. In addition, the rear-view mirror can be used as a rear-view mirror because it is in the vicinity of the user who is the driver, and it is easy to make a gesture on the front surface of the rear-view mirror, and it is not necessary to place the electronic device in the vicinity of the user in a narrow car. . As the room mirror, the room mirror provided by default in the automobile may be converted into an electronic device as it is, or may be an external room mirror.

Moreover, it is good to provide the collision reduction means which reduces the collision with the said recognition target object at the time of a gesture in the housing | casing provided with a gesture detection means as the means 26. FIG.
In this way, it is possible to reduce the recognition target from colliding with the housing during a gesture. As the collision reducing means, for example, a collision preventing means that is a means for preventing a collision, or an impact absorbing means that is a means for absorbing an impact when a recognition target object collides with a housing in the event of a collision. It is good to set it as the structure provided with at least any one of these.
For example, it is preferable that at least a part of the ridge corner or the protruding corner of the housing including the gesture detection means for recognizing the gesture is formed in a chamfered shape.
In this way, even if an object that makes a gesture, for example, a user's hand accidentally hits the case, the hand side is not damaged and the case side is damaged. It becomes difficult. In the case of forming it in a chamfered shape, it is preferable that the curved surface has no discontinuous portion as much as possible. In combination with this (or alone), the housing may be surrounded by a material having a buffering effect (for example, elastic synthetic rubber). In particular, for example, if the configuration including the configuration of the means 1 and the configuration of the means 28 is used, it is possible to know that the gesture is being recognized by sound, and the recognition target object collides with the housing during the gesture recognition. Can be reduced. For example, if a sound is generated during gesture recognition, there is a possibility of making it easy to make a gesture without looking at the casing provided with the gesture detection unit, and at that time, there is a possibility of hitting a recognition object or the like on the casing However, such a fear can be reduced by doing so.
Further, as the means 27, it is preferable to provide a place where the protective member is removed for at least a part of the gesture detection direction of the housing provided with the gesture detection means for recognizing the gesture.
For example, a transparent plastic thin film made of polyethylene or the like is preferable as the protective member. However, when such a protective member is present, the device may be used without being peeled off because the device is not damaged. . However, the adhesiveness with respect to the apparatus side of a protection member may fall by using over time, and it may peel partially. At this time, there is a possibility that the peeled protection member is shaken within the detection range of the gesture detection means and operates as if it is mistaken for a gesture. This can cause malfunction. For this reason, for example, by removing a part that is likely to peel off the protective member in advance at the time of shipment, or by removing a part that may enter the detection range of the gesture detecting means if it is peeled off, the peeled off protective member becomes a user's gesture. As well as the hassle of removing the peeled off part by the user. Moreover, as a protection member, it is good to use the protection member at the time of conveyance of the housing | casing which has a gesture detection means. In particular, the electronic information system may be provided with a member that is watched by the user during use, and the protective member may be a protective member for the member that is watched during 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 the member to be watched during use is highly necessary to be protected especially during transportation.
Further, the protection member may be provided across the gesture detection direction of the gesture detection means and the display unit, and a portion from which the protection member is removed may be provided for at least a part of the gesture detection direction. In addition, in a configuration in which the gesture detection direction of the gesture detection unit is located near the end instead of the center of the protection member, a location where the protection member is removed may be provided for at least part of the gesture detection direction. This is because the protective member is particularly easily peeled off on the side near the end of the protective member, and the peeled protective member is likely to obstruct the user's gesture.

Further, as means 28, it is preferable to provide shielding means for making it difficult to visually recognize the gesture detection means from the outside with respect to at least a part of the housing provided with gesture detection means for recognizing a gesture.
It is good in terms of design that the gesture detection means housed in the housing is not easily viewed from the outside. However, since the gesture detection means may have an opening that opens in the shape of a window in the casing in order to perform a detection operation, the gesture detection means inside the casing may be viewed from the outside. Therefore, by providing a shielding means for making it difficult for the gesture detection means to be visually recognized on the casing, the user cannot see the gesture detection means and feels good impression about the casing design. The shielding means must not interfere with the detection of the gesture detection means. For example, when the gesture detection means is detected by optical means such as infrared rays, the infrared rays can be detected and visible light can be transmitted. It is preferable to arrange a transmissive body having such characteristics that it is not transmitted by being reflected or absorbed. In particular, for example, if the configuration including the configuration of the means 1 and the configuration of the means 28 is used, a sound is produced during gesture recognition. There is a possibility that the user may see the case, and there is a higher possibility that the gesture recognizing means will be disturbed, but this possibility can be reduced.
Further, as the means 29, a gesture detection means for recognizing a gesture and a distance shortening means for making the distance to an object existing in the gesture detection direction of the gesture detection means equal to or less than a predetermined value may be provided in the casing.
For example, the wall surface or glass surface of the housing exists as an object in the gesture detection direction of the gesture detection means in the housing. For example, a detection medium such as an infrared ray or an ultrasonic wave is output from the gesture detection means, but there is a possibility that the detection may be hindered due to a long distance to the object. Therefore, such a problem can be prevented by providing the distance shortening means.

Further, as a means 30, when there is a shielding object that hinders gesture detection in the detection area of the gesture detection means for recognizing a gesture, the gesture detection means does not detect the shielding object or receives detection data. It is better to detect user gestures without using them.
As a result, the movement of the shielding object is not mistaken for the user's active gesture, and the user can operate with the gesture without feeling operational stress even when the shielding object is placed.
For example, when an electronic information system is installed in a room mirror near the windshield of a vehicle as a vehicle system, gesture detection is performed when the user operates the sun visor, for example, as a shield near the windshield. Even if an operation is performed so as to be within the detection area of the means, the user can make a gesture.
Further, as the means 31, the gesture detection means for recognizing a gesture does not detect the shielding object based on the fact that the shielding object exists in the detection area for a predetermined time, or does not use the detection data. It is better to detect gestures.
This is a gesture detection method when there is a specific shielding object, and is a condition for determining that it is not a gesture for performing a predetermined process by stopping for a predetermined time in the detection area. It is. Since the user only has to arrange the shield so as to be stopped for a predetermined time, the user can perform gesture operation without feeling operational stress. In particular, in vehicles, in order to ensure safety during traveling, it is a general rule that objects in the vehicle are fixed. Therefore, if there is an object that may enter the gesture recognition area, the object is likely to be fixed after the position is changed. For example, in the case of a room mirror type device including a gesture detection means, the position of the sun visor of the vehicle adjacent to the room mirror can be adjusted, but is fixed after adjustment. As described above, 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 provide this configuration particularly in equipment installed in a vehicle.
Further, as the means 32, the control means is preferably controlled so that the gesture is not recognized when the shielding object is detected closer to the gesture detection means than a predetermined distance.
As described above, since the gesture region cannot be secured due to the presence of the shielding object and the gesture itself may be disabled, it is possible to prevent a malfunction by making the gesture not recognized. In addition, by placing a shield in an area where the user cannot input gestures, gesture input can be actively stopped by the user's intention.
Further, as the means 33, the electronic information system may be an electronic device mounted on a vehicle. This is because a vehicle-mounted electronic device is often operated during driving, and therefore it is advantageous to execute a predetermined process in relation to sound by a gesture.
It is preferable from the point of simple operation that no means other than the gesture detection means is provided as an 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 to be viewed by the user such as having a display means or a mirror) so that no other operation input means is provided. As a result, functions other than the operation input can be exhibited.
Further, as the means 34, it is preferable to perform display on the casing so that the user can recognize a plurality of different gesture directions that can be detected by the gesture detection 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 formed during plastic molding.
The means 35 may be a program for causing a computer to realize the function of the control means in the electronic information system.

  According to the present invention, it is possible to acquire information as a result of a predetermined process without directly contacting a device. Moreover, since the gesture is accompanied by a sound, the contents of the predetermined process can be understood by the sound.

Hereinafter, an embodiment of a radar detection apparatus 10 which is an electronic apparatus embodying an 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 vehicle rearview mirror of the present embodiment. In this radar detection device 10, a thin plate-like rectangular parallelepiped casing 13 is constituted by 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), and the front side corner rim 13b serving as a 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 a predetermined interval. A power switch (not shown) is disposed at a lower position of the main body case 11, and a slot 16 for inserting a microSD card is formed at a side surface position of the main body case 11. As shown in FIG. 2, a control board 17 is disposed in the main body case 11. The control board 17 has a horizontally long outer shape substantially corresponding to the front shape of the main body case 11. In this embodiment, the control board 17 is composed of one sheet, but it may be composed of two or more sheets.

As shown in FIGS. 2 and 3, a speaker device 20 as a notification unit is disposed in the recessed space 19 of the main body case 11. The speaker device 20 is connected to the control board 17 and outputs a predetermined sound (sound) under the control of 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 20 a (surface from which sound is output) of the vibrator faces the back direction of the main body case 11. Yes. A horn 23 extending downward is connected to the storage space 21, and a 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 central lower position of the main body case 11. . The horn 23 creates a sound transmission space in which the passage is completely enclosed. Therefore, the sound (sound) output toward the body case 11 is reflected on the wall surface of the 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 a room mirror that is installed by default in the vehicle, the sound outlet 25 is positioned below the housing 13, so that it is close to the user's ear and the sound is amplified. It is very easy to hear.
As shown in FIG. 2, a sensor board 28 on which a gesture sensor 27 as a gesture detection means is mounted is connected to the control board 17 as a separate body via a BtoB connector (not shown). The gesture sensor 27 as the gesture detection means is configured so that the distance between the front surface of the sensor and the rear surface of the mirror portion 30 on the front plate 12 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 part 30 is disposed on the front surface of the front plate 12. The mirror unit 30 is configured by forming a reflective film on the surface of a transparent glass substrate by vapor deposition (in this embodiment, chromium vapor deposition) and forming black light-shielding printing on the back surface. The radar detection device 10 is attached to a rear-view mirror provided on the vehicle by a fixing clamp portion 14. At this time, the background can be transferred to the mirror portion 30 so that the driver can confirm the rear. A first window portion 31 and a second window portion 32 are respectively formed adjacent to the right end of the front plate 12 and the mirror portion 30 as viewed from the front. The first window 31 has a rectangular shape according to the outer shape of the display panel 18, and the second window 32 is configured to be smaller than the first window 31 corresponding to the size of the gesture sensor 27 and has a rounded corner. It is a rectangular shape. The first and second window portions 31 and 32 are regions in which only the reflection film is formed on the surface of the substrate without the above-described light-shielding printing. Therefore, light can be transmitted into and out of the housing 13 at the positions of the first and second window portions 31 and 32. The display panel 18 is disposed so as to face the first window portion 31, and the gesture sensor 27 is disposed so as to face the second window portion 32. The second window 32 serves as a light projecting and light receiving path when infrared rays emitted from the gesture sensor 27 are reflected back to the object. In addition, the shape and position of these window parts 31 and 32 can be changed suitably.
In the mirror part 30, a mark 33 is formed around the second window part 32 to indicate the gesture direction and appeal the user to the position where the gesture is performed. The marks 33 are arranged in four directions on the top, bottom, left, and right so as to surround the second window 32, and are formed in a mountain-shaped polygonal line bent so as to protrude outward. The four marks 33 are vertically long as a whole. It is an orderly arrangement that resembles a diamond shape. The mark 33 is obtained by visually observing an unprinted transparent portion (however, the reflective film on the surface is covered) by partially removing the light shielding printing on the back surface of the mirror portion 30 and printing. In the vicinity of the second window portion 32 of the mirror portion 30, the front plate 12 is disposed at a slight distance from the mirror portion 30, so that when the mark 33 is viewed from the front of the mirror portion 30, it is behind the gap of the mark 33. Since the front plate 12 is viewed at a distance, the mark 33 is recognized by the user with a three-dimensional effect and is more conspicuous than mere printing.

Next, the electrical configuration inside the main body 11 of the radar detector 10 will be described based on the block diagram of FIG. In addition, although a configuration that is not directly related to the present invention is omitted, for example, a configuration similar to the conventional configuration may be employed.
The control unit 35 serving as a control unit includes a CPU, a memory such as a ROM and a RAM connected to the CPU, various peripheral circuits, an interface, and the like. The control unit 35 is connected with 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.
In the ROM of the control unit 35, a GPS information processing program for processing GPS information received by the GPS receiver 37, a microwave determination program for determining a microwave (radar wave) received by the microwave detector 38, and a radio A radio wave determination program for determining a radio wave received by the receiver 39, a gesture determination program for determining a gesture passive by the gesture sensor 27, and a sound corresponding to a detection result (recognition result) of the gesture is output from the speaker device 20. And a processing mode transition program based on a gesture for shifting to a predetermined processing mode according to the determination 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 There has been stored.

The control unit 35 executes functions such as a GPS alarm function, a radar wave alarm function, and a radio alarm function, which are basic functions of the radar detector 10. In addition, the control unit 35 outputs a sound in accordance with the detection (recognition) of the gesture within the detection range of the target such as a hand held by the user recognized by the gesture sensor 27 as the target or some object held in the hand. The following processing is executed while performing control. As a gesture, in this embodiment, a hand or an object is moved linearly from right to left, from left to right, from bottom to top, or from top to bottom so as to cross the front of the gesture sensor 27. Gestures to be recognized are recognized. Further, 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 gesture recognition of the gesture sensor 27 in the present embodiment, 1) change of volume, 2) change of standby screen, 3) change of setting screen, 4) setting from standby screen Transition to screen 5) Transition from the setting screen to the standby screen is executed.

  Gesture sensor 27 in the present embodiment is a known gesture sensor, and detects two gestures of an object approaching state and a moving state (also serves as a proximity sensor to detect the approaching state). As a specific configuration, the gesture sensor 27 includes an infrared light emitting LED and four photo sensors. Each photo sensor detects light reflected from the light emitted from the infrared light emitting LED and hits the object, and changes in the amount of light are detected. Each photosensor is acquired as a numerical value, and the distance to the target object and the moving direction of the target object are calculated based on a predetermined arithmetic expression 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. While it is possible to determine the distance to the object and the moving direction of the object within the range covered by the detection capability of the gesture sensor 27, a predetermined space area is set as follows with the gesture sensor 27 as the center ( Actually, it is determined by the numerical value of the sensor). Sound output control and predetermined processing are executed based on this region.

As shown in FIG. 5, the coordinates of z_th (_th represents a threshold value) that are equidistant from the gesture sensor 27 are set with reference to the virtual plane p on which the gesture sensor 27 exists. Equal distance means a distance at which it is possible to determine that the light amount data (detected value) detected by the gesture sensor 27 is equivalent. This z_th is a reference for outputting sound in the present embodiment. Hereinafter, a hemispherical space region surrounded by z_th is referred to as a sound output reference region Z.
In addition, a region surrounded by a square frustum that is vertically inverted in the sound output reference region Z is obtained. The region surrounded by the quadrangular pyramid is the four corners of the lower base that are the intersections of the four corners of the upper base on z_th that are equidistant from the plane p and the plane p near the gesture sensor 27. It is an area surrounded by four line segments E1 to E4 connected to each other. The coordinates on each line segment are (+ x_th, + y_th) (+ x_th, -y_th) (-x_th, + y_th) (-x_th, -y_th), respectively. The moving direction of the object is detected based on the coordinates in the x and y directions calculated in the space inside the quadrangular pyramid. This is an area set in order to make it easy to calculate the movement direction of the object when passing through the origin and the determination of the passage of the object through the origin with the position of the gesture sensor 27 as the origin. Hereinafter, an area surrounded by the square frustum is referred to as a movement direction determination area Q. In the present embodiment, the longitudinal direction of the housing 13 is taken as the x-axis direction, and the direction perpendicular thereto is taken as the y-axis direction.
In addition, since the area is arbitrarily set, the distance z_th can be changed as appropriate 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. Along with the change in the distance of z_th, the size of the moving direction determination area Q existing inside thereof also changes. Further, the shape of the moving direction determination area Q (that is, the area that determines the moving direction and associates it with a predetermined process) is not limited to the above but can be changed. For example, the movement direction determination area Q may coincide with the sound output reference area Z.

In the electrical configuration as described above, an example of specific processing 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 performed by the control unit 35 based on the detection value of the gesture sensor 27 will be described in relation to specific objects in some gestures. Here, a gesture that can determine “predetermined processing” to be described later will be described as an example. However, since the movement of the object is not simple, there may be other gestures than the following.
In addition, the user may recognize the gesture before the object enters the sound output reference area Z, and may recognize the gesture after leaving the sound output reference area Z. In terms of recognition of a gesture for outputting a sound, entering the sound output reference area Z is considered to be the start of an objective gesture. Similarly, the movement of the object from the sound output reference area Z is considered to be the end of the gesture. In addition, when gesture recognition fails (when it is not determined as a predetermined gesture), no sound is produced, so that the sound is produced because the movement of the object is recognized as a gesture. is there.

(1) First movement of an object during a gesture (part 1)
This is a stage where the target object approaches the gesture sensor 27 from a distance and enters the sound output reference region Z. Basically, this process always occurs as sound output control. When the control unit 35 reads the detection value of the gesture sensor 27 and determines that the target object ("hand" in FIG. 6) exists in the sound output reference area Z (exceeds a certain numerical value as a threshold) If it is determined that the gesture is present at the position indicated by A in FIG. 6, the sound of the first scale (here “Le”) is output from the speaker device 20. The control unit 35 reads the detection value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and when it is determined that the sound output is within the sound output reference area Z, the sound of “R” is output without interruption. To continue.
On the other hand, when the object leaves the sound output reference area Z without entering the movement 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. Stop. In other words, as an assumed case, for example, when an object accidentally approaches the gesture sensor 27 and once enters the sound output reference area Z, it reverses and leaves the sound output reference area Z. It is. In that case, “predetermined processing” described later is not selected.

(2) First movement of the object during the gesture (part 2)
In this state, the gesture further enters and passes the front surface of the gesture sensor 27. When the control unit 35 reads the detection value of the gesture sensor 27 and determines that the target is a numerical value that 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). That is, if it is determined that the gesture is present at the position indicated by B in FIG. 6, a second scale different from (1) (the second scale may be higher than the first scale, Then, the sound “Fa #”) is output from the speaker device 20. At this determination timing, the control unit 35 stops the “le” sound. In this way, the sound is changed and output in a state where the user can recognize that the sound has changed continuously.
The control unit 35 reads the detection value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and when it is determined that it is within the movement direction determination region Q, the sound of “Fah #” is output without interruption. Continue output.
Here, the control unit 35 determines that the object in the movement direction determination area Q is “a. When the object crosses the front surface of the gesture sensor 27 and leaves the movement direction determination area Q” and “b. Different voice control is executed in the case of “withdrawing from”. a. In the case of (3), the process proceeds to (3) below. On the other hand, b. In this case, that is, as an assumed case, for example, an object accidentally approaches the gesture sensor 27 and enters the moving direction determination area Q within a very short time, and then reverses and leaves the sound output reference area Z to the outside. In this case, since the determination of (1) above occurs, the control unit 35 changes the sound from “F #” to “L”. In this case, “predetermined processing” described later is not selected.

(3) First movement of the object during the gesture (part 3)
In this state, the gesture sensor 27 is gradually separated from the gesture sensor 27. The control unit 35 reads the detection value of the gesture sensor 27, and performs the a. 6 is satisfied, and it is determined that the object is present in the sound output reference area Z (when a certain numerical value is used as a threshold value, or exceeds or falls below), that is, the position indicated by C in FIG. (1) (3) is different from (1) and (2). ((The third scale may be higher than the second scale. Here, “La”) Is output from the speaker device 20. At this determination timing, the control unit 35 stops the sound of “Fa #.” In this way, the scale is changed and output in a state where the user can recognize that the sound has changed continuously. When the control unit 35 reads the detection value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment) and determines that it is within the sound output reference area Z, the sound of “La” is not interrupted. of To continue the force.

(4) First movement of the object during gesture (part 4)
In this state, after passing through the front surface of the gesture sensor 27, the sound sensor is out of the sound output reference area Z. The control unit 35 reads the detection value of the gesture sensor 27, and performs the a. 6 is satisfied, and the object is determined to be a numerical value that has departed from the sound output reference region Z (when a certain numerical value is used as a threshold value that exceeds or falls below), that is, at a position indicated by D in FIG. If it is determined that the gesture is an existing gesture, 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” varies depending on the moving direction of the object. This sound is a recognition completion sound, and the frequency of the recognition completion sound and the previous recognition sound is set larger than the frequency between the sounds that change during the recognition. It is also desirable that the length of the sound be shorter than the length of the sound generated during recognition. This is determined by the moving direction in the moving direction determination area Q in (2) above. In the present embodiment, four moving directions of “moving from below”, “from above to below”, “from left to right”, and “from right to left” are prepared as the moving directions of the object. “Predetermined processing” to be described later is associated. That is, the first gesture is recognized as a different gesture for each direction. When the controller 35 determines that the movement in the movement direction determination area Q is “from the bottom to the top”, the sound having the highest pitch among the sounds output during the recognition (that is, in the present embodiment, the above-described first “So” is output as a recognition confirmation sound (for example, activation process confirmation sound) that is in a higher sound range than “La” of the third scale and is a short sound “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”, “Le” is output. This “Le” is one octave higher than the “Le” in the first scale. Similarly, when it is determined that the movement is “from right to left”, “mi” is output. These sounds correspond to “a process that varies depending on the moving direction of the object” executed by the control unit 35 described later. Then, when separated from D in FIG. 6 (when moving to the right in the figure), the control unit 35 is based on the detected value of the gesture sensor 27 to be detected (that is, when a certain numerical value is used as a threshold value, or exceeds or falls below). Stop output.
(5) First movement of the object during gesture (part 4 variation)
After passing through the front surface of the gesture sensor 27, it is outside the sound output reference area Z and is stopped in the vicinity thereof. The control unit 35 reads the detection value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and the numerical value at which the object leaves the sound output reference region Z and remains in the vicinity of the sound output reference region Z. And when a predetermined time (for example, 0.3 seconds) or more has elapsed, that is, when it is determined that the gesture is long at the position indicated by D in FIG. Specifically, the sound corresponding to the four moving directions, that is, any one of “So”, “Do”, “Le”, and “Mi” that is the same as the above-mentioned recognition definite sound is output. This intermittent sound corresponds to a so-called “long press mode” in “predetermined processing” executed by the control unit 35 described later. Then, when separated from D in FIG. 6, as in (4), 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 used as a threshold value and exceeds or falls below it). Let

Regarding the above four moving directions, the moving direction of the object does not always move accurately horizontally or vertically. For example, when an object moves in an oblique direction, a case where both horizontal and vertical can be taken occurs. The control unit 35 compares the horizontal component and the vertical component on the basis of the obtained numerical value, selects the greater one, and selects whether the movement is horizontal or vertical.
Note that the moving direction is determined when the object leaves the sound output reference area Z (goes out of z_th). In other words, a. In this stage, the predetermined process is not selected but is determined yet, and is determined based on a detection value detected by the gesture sensor 27 at a later timing. The predetermined processing may be canceled or changed depending on the movement of the object at the position where the sound of “3” is output in (3).

(6) Second Movement of Object During Gesture As shown in FIG. 7, the control unit 35 reads the detection value of the gesture sensor 27 and the object is within the sound output reference area Z (including the movement direction determination area Q). If it is determined that the target is stopped for a predetermined time (for example, 2 seconds) or more, a predetermined tone with a tone of “Kari” that is different from any of the above sounds is used. Sound is output from the speaker device 20 intermittently. The stop state is determined on the basis that the detection value of the gesture sensor 27 does not change at all or changes only within a narrow numerical range.
Further, the control unit 35 reads the detection value of the gesture sensor 27 at a predetermined timing (every 12 ms in the present embodiment), and stops the output of sound when the stopped object moves. After the stopped object moves, sound output control is performed according to the above conditions (1) to (4) according to the position of the object.
As a premise of the audio output process based on this stop, if the target object enters the sound output reference area Z and satisfies the above conditions (1) and (2), (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 it is further confirmed. Next, the predetermined processes executed by the control unit 35 will be described in conjunction with actual gestures and sounds output with the gestures. In the initial setting, the distance z_th of the sound output reference area Z is set to 10 cm. Further, if the object crosses the moving direction determination area Q very quickly, the difference between the detection values of the gesture sensor 27 cannot be acquired, resulting in an error. 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 that predetermined processing is confirmed accordingly.
A. Volume change (from bottom to top)
As shown in FIG. 8, radar detection is performed by maintaining a distance of, for example, 7 cm on the front surface of the front plate 12 of the radar detection device 10 and passing a hand as an object from the lower position of the radar detection device 10 to the front surface of the gesture sensor 27. A gesture is made to slide once to the position where the device 10 is pulled out. At this time, the control unit 35 determines that there is a gesture in which the object slides once from the lower side to the upper side on the front surface of the gesture sensor 27 and increases the volume by one level from the current state. In conjunction with this gesture, the control unit 35 outputs sounds from the speaker device 20 in the order of “Le” → “Fa #” → “La” → “So” (the first of the objects in the above series of gestures). Equivalent to 1 movement).
On the other hand, as shown in FIG. 9, the hand is stopped near the upper edge of the housing 13 after passing the front of the gesture sensor 27 from the lower position of the radar detection device 10. This position corresponds to a position outside 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, the object exists in the sound output reference area Z as a detection value outside the set sound output reference area Z. 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 more, it is determined as a so-called “long press” mode, and the control unit 35 continuously increases the sound volume from the current state. To control. At this time, in conjunction with this gesture (corresponding to the above “part 4 variation”), the control unit 35 performs the speaker device in the order of “Le” → “Fa #” → “La” → “So” intermittent sound. Sound is output from 20. The control unit 35 terminates the process when the object is released from the stop state or when the volume is maximized (a state in which no further change is possible), and stops the intermittent sound.

(From top to bottom)
On the contrary, as shown in FIG. 10, a gesture is performed in which the hand is slid 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 falls below the radar detection device 10. At this time, the control unit 35 determines that there is a gesture in which the object slides once from the upper side to the lower side on the front surface of the gesture sensor 27, and lowers the volume by one level from the current state. At this time, in conjunction with this gesture, the control unit 35 outputs sounds from the speaker device 20 in the order of “Le” → “Fa #” → “La” → “Do” (the object of the series of gestures described above). Equivalent to the first movement).
On the other hand, as shown in FIG. 11, the hand is passed through the front surface of the gesture sensor 27 from the upper position of the radar detection device 10 and then stopped near the lower edge of the housing 13. This position corresponds to a position outside the sound output reference area Z adjacent to the sound output reference area Z. When detecting a stop state at this position for a predetermined stop time (for example, 0.3 seconds) or longer, the control unit 35 determines that the mode is a so-called “long press” mode, and performs control so that the sound volume is continuously reduced from the current state. At this time, in conjunction with this gesture (corresponding to the above “fourth variation”), the control unit 35 performs the speaker device in the order of “Re” → “Fa #” → “La” → “Do”. Sound is output from 20. The control unit 35 terminates the process when the object is released from the stop state or when the volume is maximized (a state in which no further change is possible), and stops the intermittent sound.

B. Changing the standby screen (from left to right)
As shown in FIG. 12, a distance of, for example, 7 cm is maintained on the front surface of the front plate 12 of the radar detection device 10, and a hand as an object is passed from the left position of the radar detection device 10 to the front surface of the gesture sensor 27. A gesture is made to slide once to the position where the detection device 10 is pulled to the right. At this time, the control unit 35 determines that there has been a gesture in which the object slides once from the left to the right in front of the gesture sensor 27 and displays the current standby screen displayed on the display screen in the right direction. The screen is displayed so as to be slid so as to display the next standby screen in the adjacent position that has been left behind and displayed, on the display screen of the display panel 18. At this time, in conjunction with this gesture, the control unit 35 outputs sounds from the speaker device 20 in the order of “Le” → “Fa #” → “La” → “Le” one octave (in the series of gestures described above). Corresponding to the first movement of the object in FIG.
The standby screen of the present embodiment is looped as calendar → clock → speed → eco-drive mode → positioning information → rotation of all standby screens → display off → radar scope → drive mode. Will return to the initial standby screen mode.
On the other hand, as shown in FIG. 13, the hand is passed through the front surface of the gesture sensor 27 from the left position of the radar detector 10 and then stopped near the right edge of the housing 13. This position corresponds to a position outside 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 more, the control unit 35 determines a so-called “long press” mode and sequentially changes the looped standby screen to a display screen. Let
At this time, in conjunction with this gesture (corresponding to the above “part 4 variation”), the control unit 35 performs the speaker device in the order of “Le” → “Fa #” → “La” → “Re” intermittent sound. Sound is output from 20. The control unit 35 ends the process with the object being released from the stop state, and also stops the intermittent sound.

(From right to left)
On the contrary, as shown in FIG. 14, a gesture is performed to slide the hand once from the right position of the radar detection device 10 to the position where the hand has left to the left of the radar detection device 10. At this time, the control unit 35 determines that there has been a gesture in which the object slides once from the left to the right on the front surface of the gesture sensor 27 and displays the current standby screen displayed on the display screen in the left direction. The screen is displayed so as to be slid so as to display the next standby screen in the adjacent position that has been left behind and displayed, on the display screen of the display panel 18. At this time, in conjunction with this gesture, the control unit 35 outputs sounds from the speaker device 20 in the order of “Le” → “Fa #” → “La” → “Mi” (the target object in the above series of gestures). Equivalent to the first movement).
On the other hand, as shown in FIG. 15, the hand is passed through the front surface of the gesture sensor 27 from the right position of the radar detector 10 and then stopped on the display panel 18 near the left side. This position corresponds to a position outside the sound output reference area Z adjacent to the sound output reference area Z. As a result, the control unit 35 determines the so-called “long press” mode, and sequentially changes and displays the looped standby screen on the display screen.
At this time, in conjunction with this gesture (corresponding to the above “part 4 variation”), the control unit 35 performs 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 with the object being released from the stop state, and also stops the intermittent sound.

C. Transition to the setting screen As shown in FIG. 16, a gesture is performed to maintain a distance of, for example, 9 cm at a position facing the gesture sensor 27 in front of the front plate 12 of the radar detector 10. At this time, the control unit 35 determines that there has been a gesture in which the object has stopped for a predetermined time (for example, 2 seconds) or more on the front surface of the gesture sensor 27, and the standby screen is displayed on the display screen of the display panel 18 by default. Transition from the state to the setting screen.
The setting screen of the present embodiment is a transition initial screen, ity. Start from MAP → Mode (and its submenu) → Brightness (and its submenu) → Flex dimmer (and its submenu) → Radar warning sound (and its submenu) → Sensor confirmation sound (and its submenu) ) → Sensor response 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 it is displayed on the display screen of the display panel 18 one after another from the left to the right or from the right to the left by the same operation as “B. Changing the standby screen”. The setting menu to be displayed can be changed. In the submenu, the setting menu 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 “A. . 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. By doing so, it is possible to execute. After returning to the standby screen, the gesture “B. Change of standby screen” can be performed.
When the control unit 35 detects a stop state at this position for a predetermined stop time (for example, 2 seconds) or longer, the control unit 35 intermittently generates a “crisp” sound as described in the second motion of the object in the gesture (6). Are output from the speaker device 20 (corresponding to the second movement of the object during the 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) is output.

Next, a process in the case where there is some shielding object that interferes with the determination of the gesture in the sound output reference area Z will be described.
For example, it is assumed that the radar detection device 10 is used in a vehicle. In that case, there is a case where a sun visor is used because of sunlight. Then, depending on the mounting position of the radar detector 10, the sun visor may become a shield and enter the sound output reference area Z. The following is a process for a user to perform a gesture without any trouble even if such an obstruction is present, and a normal gesture is recognized after offsetting (subtracting) a detection value based on the amount of light from the obstruction. Is.

(Determination of the presence or absence of shielding in the initial state)
First, the control unit 35 determines the following three states in the initial state where there is no shielding object.
a. A certain obstruction (which is determined without distinguishing an object, the same applies hereinafter) enters the sound output reference area Z, and a predetermined time (120 ms) has been stopped without determining a predetermined process. When judged b. When it is determined that some kind of shielding object enters the sound output reference area Z and the gesture of “(6) Second movement of object during gesture” has been performed for 5 seconds or longer c. When it is determined that some kind of shielding object enters the sound output reference area Z and the gesture of “(5) first movement of the object in the gesture (part 4 variation)” has occurred for 8 seconds or longer.

Where: a. Is a case where no transition is made to the processing mode due to the entering obstacle. The reason why 120 ms is set is that the control unit 35 calculates the offset every 120 ms, so that it corresponds to the interval. In this case, the control unit 35 performs a calculation for offsetting the detection value of the gesture sensor 27 changed by the shielding object, and uses the state of the gesture sensor 27 after the offset as a reference for detection.
B. And c. Each is a state in which the display screen and the volume have changed due to transition to some processing mode, and a stop gesture different from a normal gesture is set by setting a long time. In these cases, since an unintended process has been executed by the shielding object, the control unit 35 is forced to shift to a standby screen set as a default. Similarly, by canceling a process that may have been started due to an unintended input by forcing the sound to a sound volume set as a default. And then a. Similarly to the above, the control unit 35 performs a calculation for offsetting the detection value of the gesture sensor 27 changed by the shielding object, and uses the state of the gesture sensor 27 after the offset as a reference for detection.
The above is schematically described as shown in FIG.

(Judgment of presence or absence of shielding during offset calculation)
Normal gesture recognition is executed in a state where the calculation for offsetting is started and the light quantity of the shielding object is canceled as described above. The controller 35 always calculates an offset at a predetermined timing (120 ms) during gesture recognition, and uses the latest state of the gesture sensor 27 as a reference for detection.
Here, there is a case where the shielding object once stayed in the sound output reference area Z moves. For example, the sun visor shakes or changes its position depending on the direction of sunlight, or it is considered that the sun visor is separated from the sound output reference area Z and returned to the original position. As a case where the shielding object moves, the control unit 35 determines the following three states.
d. When the shield has moved, but the predetermined process has not been determined e. When it is determined that the gesture “(6) Second movement of the object during the gesture” has been performed for 5 seconds or longer by moving the shielding object f. When it is determined that the above-mentioned “(5) first movement of the object during gesture (part 4 variation)” gesture has been performed for 8 seconds or longer by moving the shielding object d. For example, it is assumed that the shield in the sound output reference area Z slightly swings due to vibration. In this case, since there is no 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 the display screen and the volume have been changed after being recognized as a gesture and entering a certain processing mode. In this case, the control unit 35 sends the above b. And c. In the same manner as described above, the screen is forcibly shifted to the standby screen, the sound is forcibly set to the default volume, and thereafter the calculation value for offsetting the detection value of the gesture sensor 27 is performed at a predetermined timing as described above.
The processing executed by the control unit 35 is the above b. And c. But with a different purpose. b. And c. In the initial state, this corresponds to the case where the shielding object enters the sound output reference area Z from the outside, and corresponds to the state where the offset has not yet been calculated, e. And f. Corresponds to the time when the shielding object enters the sound output reference area Z and is calculating to offset the shielding object (after the offset calculation starts).
The above is schematically described as shown in FIG.

(When the shield is near the gesture sensor)
When the shielding object is arranged very close to the gesture sensor 27, a normal gesture cannot be performed because there are few gaps in the space. That is, detection by the gesture sensor 27 is physically impossible. Therefore, assuming such a state, processing is performed so as not to perform gesture recognition when the shielding object is arranged very close to the gesture sensor 27. Specifically, during the gesture recognition, the control unit 35 always has a shielding object within a predetermined distance (for example, 3 cm) from the gesture sensor 27 at a predetermined timing (120 ms), and this is a predetermined time (for example, 5 seconds). It is determined whether or not it has stopped. Then, when it is determined that there is an obstacle within a predetermined distance and that it has stopped for a predetermined time, the control unit 35 cancels the detection value of the gesture sensor 27 in the calculation. That is, although gesture recognition by the gesture sensor 27 is performed, the gesture sensor 27 is not in operation in the same manner as if nothing is detected (actually the detection of the gesture sensor 27 is actually stopped). May be allowed).
On the other hand, when the control unit 35 determines that the gesture sensor 27 has moved beyond a predetermined distance, the calculation using the detection value of the gesture sensor 27 is resumed.

Next, a process when the “sensor reaction range” set by the user on the setting screen is temporarily returned to the default state (here, the range of 10 cm) will be described. This process assumes the following case.
If the sensor response range is in the default state, the range is set to be wider, so that there is a possibility that some processing will be executed by entering the sensor response range (output reference region Z) at some time. Therefore, it is preferable that the sensor reaction range can be set to, for example, normal (6 cm) or narrow (4 cm) by user setting. However, even in such a case, it is preferable to return to the default state with a wide range in order to operate quickly according to the situation. Here, as an example, the control unit 35 for temporarily widening the “sensor reaction range” in order to facilitate the operation of muting the notification when any warning is issued from the radar detector 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 an alarm is informed, and if it is determined that the alarm is informed, it 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 is temporarily terminated. That is, it is not necessary to change the sensor response range.

On the other hand, if it is determined in step S11 that the current sensor reaction range is not 10 cm (that is, 6 cm or 4 cm), control is performed so that the sensor reaction range is 10 cm in step S12, and the flag is set to “1” in step S13. ”To end the process once. This temporarily changes the sensor reaction range to 10 cm.
On the other hand, if it is determined in step S10 that an alarm has not been notified, it is determined in step S14 whether the flag is “1”. Here, when the flag is “1”, it means that the sensor reaction range has been temporarily changed to 10 cm in the previous routine, so the sensor response range immediately before that is returned to 6 cm or 4 cm. 0 ”. On the other hand, if the flag is not “1” in step S14, the process is terminated as it is because the previous sensor reaction range has not been changed.
With such a control, when an alarm is informed, the sensor reaction range of a distance of 10 cm that is easily operated by the user is temporarily changed, and the user can easily suppress the volume by a gesture operation. On the other hand, when the alarm is completed, the original sensor reaction range is restored, so that the user can save the trouble of setting again.

With the configuration as described above, the radar detection device 10 of the present embodiment has the following effects.
(1) The radar detection device 10 is not required for an input unit or a touch panel configured by, for example, an electrostatic switch for actual touch operation as in the prior art, and can be operated by four-direction operation + approach stop operation. The cost is reduced, and the components such as the input unit are not necessary, so that the weight can be reduced. This is particularly suitable when the radar detection device 10 is installed in a vehicle with much vibration.
(2) Since a so-called high-end machine with many various functions associated with a radar detection device requires fine settings, an input unit such as a remote control or a touch panel is inevitably required. However, with low-end machines, which tend to have few setting items, there is no oversight because it is a simple operation even with gesture input, so it is optimal for low-end machines. In a high-class machine, it is not necessary to mount the gesture sensor 27, and even if a gesture function is provided, it is merely an auxiliary input, resulting in an increase in cost. That is, it is possible to provide a device such as a radar detection device that does not include any means other than the gesture detection unit as an operation input unit to the device from the user.
(3) Although the radar detection device 10 also serves as a rearview mirror, since it can be input by gestures in this way, the conventional switch area on the side of the mirror portion is no longer necessary, and a full mirror is provided. The mirror area is relatively increased, and the function as a room mirror is improved for the user. In addition, since the user can operate without touching the mirror surface, it becomes difficult to get dirty with fingerprints.
(4) Since the user can shift the radar detection apparatus 10 to a desired processing mode only by executing a predetermined gesture, it is not necessary to visually search for an input unit or the like for actually touching and inputting. Operationally advantageous. Moreover, since it is not necessary to search an input part etc. if it is driving | running | working, it will be able to concentrate on driving | operation.
(5) For example, an input unit or a touch panel for touching operation is not touched, so that the housing 13 is hardly soiled, and deterioration due to contact can be prevented.
(6) The user can remember a gesture pattern that emits the same sound by repeating the gesture several times, and can easily select a desired process by executing the gesture. At that time, the gesture pattern can be accurately memorized based on the kind of sound and the timing of outputting a plurality of sounds.
(7) When a gesture for executing a predetermined process is included in a series of gestures, 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 shielding object such as a sun visor that interferes with the determination 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. Even if there is actually no reliable input means such as a section, the input is definitely possible.
(9) Even when the sensor reaction range is set to, for example, normal (6 cm) or narrow (4 cm) in the user's setting, when the alarm is being notified, the user can temporarily operate 10 cm. Since it is changed to the sensor response range of the distance, it becomes easy for the user to suppress the volume by gesture operation. On the other hand, when the alarm is completed, the original sensor reaction 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, when the radar detection device 10 is installed in the vehicle, it is close to the ear and the sound is amplified in the horn 23, so that it is for the user. It is very easy to hear.
(11) The four marks 33 indicating the sensor positions indicate the gesture direction (up / down / left / right) for executing predetermined processing at the same time, and are easy to understand for the first user.

The present invention may be embodied in the following aspects.
In the radar detection device 10 of the above embodiment, as shown in FIG. 2, the sensor board 28 having the gesture sensor 27 mounted on the control board 17 is connected as a separate layer in a stacked manner via a BtoB connector (not shown). It was. However, when the gesture sensor 27 is to be arranged close to the rear surface of the mirror unit 30 by such connection, the distance from the mirror unit 30 is more than expected due to the thickness tolerance of the substrate and does not fall within a predetermined range. There may be cases.
Therefore, when a gesture sensor is arranged, a configuration as shown in FIG. 19 is preferable. FIG. 19 is a partially enlarged cross-sectional view of a stationary radar detector 50. The radar detection device 50 includes a main body case 51 and a front plate 52 that form a housing 53. A transparent glass cover 54 is disposed on the front surface of the front plate 52. A sensor substrate 56 on which the gesture sensor 55 is mounted is fixed to a stud 57 formed on the front plate 52 by screws 58. The sensor substrate 56 is connected to the main substrate 59 by a flexible cable 60.
In this manner, the sensor substrate 56 is directly and directly fixed to the stud 57 on the front plate 52 side, and the distance to the mirror unit 30 is shortened without any other member therebetween, so that the gesture sensor 55 is accurately covered 54. It becomes possible to arrange | position in the position close | similar to. In short, since the sensor substrate 56 may be fixed to the front plate 52 side alone, it may be fixed by fixing means other than the screws 58, for example, means such as a clip. Such a gesture sensor installation mechanism 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 target object in the gesture. At this time, the gesture can be considered as a single gesture for the whole output of several sounds, with a gesture corresponding to a certain sound. It can be thought of as a single gesture. In other words, for example, the following first gesture may be considered as a gesture starting from 1 and ending with 4 and may be considered as a single gesture having a start and an end only by “first gesture (2)”. .
In addition to the above gestures, for example, a gesture in which an object crosses the front surface of the gesture sensor 27 in an oblique direction or a gesture in which a circle is drawn may be employed. Further, for example, the gesture may be such that the object is opposed to the gesture sensor 27 and approached from a separated position (or conversely separated).
The second window portion 32 of the mirror portion 30 has a configuration that allows the gesture sensor 27 to be viewed because visible light is transmitted. However, it is preferable to arrange a transmission film having a transmission characteristic such that light in the visible light region is reflected or absorbed so as not to show the gesture sensor 27 and only infrared light is transmitted.
The shape and position of the first and second window portions 31 and 32 can be changed as appropriate.
As other processing executed by the control unit 35 exemplified in the above embodiment, for example, as processing related to sound, output of sound (speech) and its stop, change of sound quality (timbre), change of number of sounds Further, it may be set so that a change in a sound pattern (for example, a melody), a change in a voice of guidance, and the like can be made by a gesture.
In the above-described embodiment, the four directions of up / down / left / right of the movement direction of the hand gesture are set, 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 a sound having another pitch may be used. In addition, the pitch was set so that the sound gradually increased as the object crossed the sensor response range in the above, but the sound output as the object moved increased 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 a normal (6 cm) or narrow (4 cm) by the user setting, for example, a distance of 10 cm that is easily operated by the user when an alarm is informed However, such processing may be executed in addition to the alarm notification. For example, it is a case of time notification, accident information notification, or the like. In the above description, the sensor reaction range can be set to three distances, but may be set to two or four or more. Further, after changing the sensor response range to a distance of 10 cm that is easy for the user to operate, the processing is to return the sensor response 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 other shapes. For example, in the above description, the gesture sensor 27 is disposed on the right side of the front. This is mainly intended for a user who performs a gesture with the left hand of a right-hand drive vehicle, but considers a left-hand drive vehicle. The gesture sensor 27 may be arranged on the left side (that is, it may be arranged at a position where it is easy to make a gesture according to the vehicle). Alternatively, in the above-described embodiment in which the gesture sensor 27 is disposed on the right side of the front, it is configured to be rotated 180 degrees in a plane that is changed to the mirror and attached to the vehicle rearview mirror. It is preferable to determine the attachment direction using 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 attachment direction.
In addition to the radar detection device, the present invention may be applied to, for example, a navigation device (without a radar detection function) or a drive recorder device for a vehicle.
-You may make it apply to various apparatuses other than the object for vehicles.
In the detection by the gesture sensor 27, 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. You may make it use the gesture sensor of other principles, such as what utilized the change of.
A protective sheet for protecting the mirror surface may be attached to the front surface of the mirror unit 30. In this case, the user may use it without peeling off at the time of use. However, a part of the protective sheet may be peeled off due to use over time, and the peeled protective sheet may be shaken within the detection range of the gesture sensor 27 and may behave as if it is mistaken for a gesture. This can cause malfunction. Therefore, as shown in FIG. 20, the protective sheet 62 can be attached only within a range away from the second window portion 32, or corner portions that are easily peeled off can be formed in a chamfered shape. Will not interfere with the user's gestures, and the user will not have the trouble of removing the peeled off part. In particular, a protective sheet is preferably provided on the entire surface of the mirror, and the protective sheet is hollowed along the second window portion 32. In this way, the entire mirror surface can be protected, and even when the user starts using the protective sheet without removing the protective sheet, the possibility of being recognized as a gesture by the movement of the protective sheet can be reduced.
-You may make it apply to apparatuses other than vehicle equipment.
The present invention can be freely implemented in a modified form without departing from the spirit of the present invention.
