Description

  The technology disclosed in this specification relates to an operator identification device that identifies an occupant who has operated an in-vehicle device.

  As a technique for identifying an occupant who operates an in-vehicle device, for example, there is a technique disclosed in Patent Document 1 below. In this technology, whether an operation access to an operation target device (operation device) is performed by a driver or another occupant based on image information or audio signals detected by a camera, a microphone, or a laser sensor. Identify When the operation access is performed by the driver based on this identification, the operation access that may distract from the driving operation is suppressed.

Special table 2007-526840

  The above-mentioned Patent Document 1 does not directly disclose a technique related to face recognition. For example, as a technique for recognizing a face from image information obtained by a camera, there is a technique that compares a pre-registered upper body image pattern with image information taken by a camera. In the case of such face recognition, it is difficult to recognize a face when a driver or another occupant wears a mask, glasses, or sunglasses that are not usually worn on the face. Also, image recognition processing algorithms are generally complex and require time for information processing. On the other hand, as the identification based on the sound signal of the microphone, the above-mentioned Patent Document 1 discloses a technique for identifying the driver and other occupants from the difference in the propagation time of the sound signal by the microphone. In this technique, it is necessary to provide two or more microphones for collecting each sound. In addition, when the driver and other occupants utter voices at approximately the same time, it is difficult to recognize the voice because the voice signal is disturbed. The present specification provides a technique for improving the identification accuracy of an operator while being a simple algorithm.

  The operator identification device disclosed in this specification is an operator identification device that identifies an occupant who has operated an in-vehicle device that can be operated by a plurality of occupants, and includes motion information and operation time detection output from a motion detection unit. The identification determination unit determines whether the timing when the occupant's body moves (operation timing) and the timing when the vehicle-mounted device is operated (operation timing) are synchronized based on the operation time point information output from the unit When synchronized, identification information for identifying the occupant whose body has moved is output to the in-vehicle device. Thereby, the identification determination unit determines whether the occupant whose body has moved operates the in-vehicle device by a simple algorithm that compares the operation timing output from the motion detection unit and the operation timing output from the operation time point detection unit. Determine whether. When operating the vehicle-mounted device, the occupant's body that has been operated moves. Here, “body movement” includes not only the movement of the arm and head, but also the movement of the mouth, chest and neck when speaking, and the displacement of the chest surface when breathing. For example, when the on-vehicle device is operated manually, the shoulder, arm, and hand move with the operation. Further, when the in-vehicle device is operated by voice recognition, the mouth, the neck, and the chest move along with the utterance and utterance. Therefore, by determining that the occupant whose body moves in synchronization with the operation timing when the in-vehicle device is operated is the occupant who operates the in-vehicle device, the identification accuracy is improved while being a simple algorithm.

  Note that the motion information output from the motion detection unit is information that identifies a body part that has moved, information that specifies how the body part has moved (trajectory of the moved part), and the like. Moreover, the information which specifies the seat nearest to the position where the detected body movement has occurred may be included. Based on the seat information, it is possible to specify whether the subject occupant whose body movement has been detected is the driver, the passenger in the passenger seat, or the occupant in the rear seat.

  It is also preferable to select (filter) a body part that focuses on movement according to the operated object (operation object). For example, when the voice input device is operated, only the movements of the mouth and the chest are extracted from the motion information output from the motion detection unit, their operation timing is specified, and the operation timing is compared. When the switch is operated, only the movements of the arms and shoulders are extracted from the movement information output from the movement detection unit, their operation timings are specified, and compared with the operation timings. By limiting the body part that focuses on the movement according to the operation target, it is possible to improve the accuracy of operator identification.

  Details of the technology disclosed in this specification and further improvements will be described in the embodiments of the present invention.

It is a block diagram which shows the function structural example of an agent system. It is a block diagram which shows the hardware structural example of a navigation apparatus as an example of the vehicle-mounted apparatus with which an agent system is mounted. FIG. 3A is a characteristic diagram illustrating an example of a change in body movement in response to an operation input on the touch panel, and FIG. 3B is a characteristic diagram illustrating an example of a change in body movement in response to a voice input from a microphone. It is a flowchart of an information presentation process. 5 is a flowchart of a subroutine (user identification process) shown in FIG.

  The operator identification device will be described with reference to the drawings. In this embodiment, the operator identification device is applied to an in-vehicle device on which an agent system is mounted. The agent system is a system that displays an anthropomorphic character image on the display and contributes to communication with the vehicle occupant. Provide the best information. An example of such an in-vehicle device is a car navigation device. In the present specification and drawings, an anthropomorphic character image is simply referred to as an “agent”.

  First, the functional configuration of the agent system will be described with reference to FIG. FIG. 1 is a block diagram illustrating an example of a functional configuration of the system. In this embodiment, an example in which the present invention is applied to a navigation device as an in-vehicle device will be described later. First, an agent system for a general in-vehicle device will be described.

  The agent system 2 includes an operation input unit 3, a motion detection unit 4, a user identification unit 5, an agent characteristic control unit 6, a presentation information generation unit 7, and a presentation information output unit 8. Among these, the operation input unit 3, the motion detection unit 4, and the user identification unit 5 correspond to an operator identification device.

  An input device for giving an instruction to the in-vehicle device also serves as the operation input unit 3. The operation input unit 3 has a function of detecting operation timing of the in-vehicle device and outputting operation information (operation time point information). For example, in a man-machine interface operated by a passenger touching with a fingertip, a touch sensor constituting a touch panel corresponds to this. In a man-machine interface operated by voice input, a microphone that collects voice generated by the occupant's utterance corresponds to the operation input unit 3. The operation input unit 3 is connected to the user identification unit 5, the agent characteristic control unit 6, and the presentation information generation unit 7, and outputs the detected operation information to them.

  The motion detection unit 4 has a function of detecting motion of the occupant's body and outputting motion information. As will be described later, for example, a microwave Doppler sensor corresponds to this. Examples of the movement of the occupant's body are movements of the shoulders, arms and hands when the vehicle-mounted device is manually operated, and movements of the chest, neck and lips due to speech. The motion detection unit 4 is also connected to the user identification unit 5, the agent characteristic control unit 6, and the presentation information generation unit 7, and outputs the detected motion information to these. The motion detection unit 4 may be equipped with another sensor, for example, an image sensor, instead of the microwave Doppler sensor or in addition to the microwave Doppler sensor. The motion information includes information for identifying a body part that has moved and a trajectory that has moved (information about the position where the motion started and the position where the motion stopped). There are many algorithms for detecting arm, shoulder and mouth movements from image information. The algorithm for detecting the movement of the chest or neck can be realized based on the algorithm for detecting the movement of the arm or the like. Therefore, a description of the algorithm for detecting motion is omitted.

  The motion detection unit 4 also adds information (occupant position information) identifying the seat on which the passenger is seated in the vehicle from the position where the motion is detected to the motion information. Output. Typically, when arm movement is detected, information that identifies the seat closest to the position of the detected arm among the passenger seat, driver seat, rear right seat, rear left seat, and rear center seat Is output as occupant position information. The same applies when mouth movement or chest movement is detected.

  The user identification unit 5 has a function of identifying who the person who operated the in-vehicle device is based on the motion information input from the motion detection unit 4 and the operation information input from the operation input unit 3. It is what you have. In the present embodiment, a first stage for detecting the presence or absence of body movements synchronized with the operation input timing, and a second stage for identifying individuals based on one or more biological signals obtainable from the movement information; The passengers are identified in two stages. This algorithm will be described in detail later. The user identification unit 5 is connected to the agent characteristic control unit 6 and the presentation information generation unit 7 and outputs identification information to them.

  The agent characteristic control unit 6 specifies an agent corresponding to an occupant (hereinafter referred to as “user”) determined based on the identification information output from the user identification unit 5 and determines the characteristic of the specified agent. It has a function of updating a value (agent characteristic control value) based on motion information and operation information. The agent characteristic control unit 6 is connected to the presentation information output unit 8 and outputs the updated agent characteristic control value. The agent characteristic items that change according to the agent characteristic control value include, for example, how the agent speaks and the tone of the voice (high and low), or the body shape of the agent and the brightness of the hair color. Changes based on operation information.

  For example, when the in-vehicle device is a navigation device, the operation information includes destination information input by the user and surrounding information thereof. In addition to the movement of the user's arm and head, the movement information includes a heart rate and a respiratory rate. The operation information includes, for example, the number of times a destination is selected and the number of times surrounding information is searched. In these cases, the more times a particular destination (eg, restaurant) is selected, the more friendly the agent's tone is, and the more times the specific peripheral information (eg, convenience store) is searched, the more agents The agent characteristic control value is updated so as to increase the tone of the voice. In addition, the agent characteristic control value is updated so that the larger the integrated value of the heart rate, the larger the body shape of the agent, or the brighter the color of the agent's hair, the larger the integrated value of the respiratory rate.

  The presentation information generation unit 7 provides information to be presented based on the operation information input from the operation input unit 3, the motion information input from the motion detection unit 4, and the identification information input from the user identification unit 5 ( (Presentation information) is generated. For example, according to the operation content or the requested action by the operation information, the presentation information estimated to be optimal from the user's heart rate and respiratory state specified by the identification information and the movement information, and the user's past history information Generate. The user's past history information is obtained from, for example, a database included in the system 2 or an external database. The presentation information generation unit 7 is connected to the presentation information output unit 8 and outputs the presentation information thereto.

  Specifically, for example, when the operation information is “search for nearby restaurants” and it is determined that the user is in a fatigue state from the heart rate and respiratory rate based on the motion information, Search the database for restaurants that provide effective dishes and ingredients. Then, from the search results, a restaurant with a high usage frequency is extracted based on the past history information of the user and is output. What can be estimated based on the heart rate and respiratory rate based on the motion information includes sleepiness and a relaxed degree in addition to the fatigue level.

  The presentation information output unit 8 has a function of providing information to a user via an agent. More specifically, the presentation information output unit 8 displays information to be presented by the agent based on the updated new control value input from the agent characteristic control unit 6 and the presentation information input from the presentation information generation unit 7. It has a function to output. Specifically, for example, the presentation information input from the presentation information generation unit 7 is provided to the user by being shown through an agent displayed on the display or being swayed through a speaker. The agent at this time is given its individuality by the agent characteristic control value input from the agent characteristic control unit 6. The personality is data that characterizes the character visually and visually, such as the character's body shape, hair brightness, and voice tone. Since the personality of the character changes depending on the agent characteristic control value, the agent changed to the appearance based on the user's state, hobbies, preferences, etc. guides the presentation information.

  The agent system 2 configured as described above is mounted on the navigation device 10 in this embodiment. Therefore, from here, the hardware configuration of the navigation apparatus 10 will be described with reference to FIG. The navigation device 10 is an example of an in-vehicle device on which the system 2 is mounted. Therefore, for example, the agent system 2 described above may be mounted on an in-vehicle audio device or an in-vehicle video device. FIG. 2 is a block diagram illustrating a hardware configuration example of the navigation device 10.

  The navigation device 10 mainly includes a microcomputer 11, a storage device 12, a communication device 13, a touch panel 15, a motion sensor 16, a microphone 17, a display 18, and a speaker 19. The correspondence between these hardware and each function of the agent system 2 described above is as follows. The operation input unit 3 corresponds to the touch panel 15 and the microphone 17. The motion detection unit 4 corresponds to the motion sensor 16. The user identification unit 5 and the agent characteristic control unit 6 correspond to the microcomputer 11. The presentation information generation unit 7 corresponds to the microcomputer 11, the storage device 12, and the communication device 13, respectively. The presentation information output unit 8 corresponds to the microcomputer 11, the display 18, and the speaker 19.

  The microcomputer (microcomputer) 11 typically corresponds to a one-chip microcomputer for control, a one-board microcomputer, or the like. In the present embodiment, a semiconductor memory built in the microcomputer 11 is used as the main memory used by the microcomputer 11. The microcomputer 11 also includes a serial or parallel input / output interface. In addition to these, an A / D converter or the like that converts an analog signal input into a digital signal is also built in the microcomputer 11, and an analog signal input from the touch panel 15, motion sensor 16, or microphone 17 is also included. It is configured to be able to process information.

  The storage device 12 is a memory device used as an auxiliary storage device for the database and the microcomputer 11 described above, and is a semiconductor memory device made of EEPROM or the like, or a disk drive made of hard disk, DVD, CD-ROM or the like. In addition to the route search program and map data necessary for the navigation process, the storage device 12 executes the above-described agent system program, past user history information, and an information presentation process described later. Stores programs and so on.

  The communication device 13 is a communication interface that enables information communication with an external database. The microcomputer 11 accesses an external database via the communication device 13 and searches for restaurants and the like as described above. The external database stores various data relating to clothing, food and living.

  The touch panel 15 is an input device provided on the surface of the display 18 and is a kind of pointing device. There are various methods such as a resistance film method and an electrostatic capacity method, and all of them detect the touched position information by an analog value or a digital value and output it to the microcomputer 11. Thereby, the microcomputer 11 determines whether or not there is an input at a position overlapping the image such as a button or a pictogram displayed on the display 18.

  The motion sensor 16 is a collective term for a plurality of sensors that detect the movement of the user's body, and corresponds to, for example, a microwave Doppler sensor in addition to an image sensor. The image sensor detects the movement of the user, particularly the head and arms, by analyzing the image over time. A description of the technique for identifying the head and arms from the image and the technique for identifying the movement thereof will be omitted. Further, from the position of the camera and the position in the image where the movement is detected, it is specified which seat the passenger belongs to and the information (occupant position information) is generated.

  Further, in this embodiment, the microwave Doppler sensor irradiates the occupant with microwaves, measures the occupant's body surface displacement speed relative to the sensor from the Doppler shift of the reflected wave, converts the speed into a displacement amount, and converts it into an analog amount. Output to the microcomputer 11. Therefore, when detecting the body surface displacement and behavior of the driver (occupant seated in the driver's seat) among the passengers, microwaves are irradiated toward the driver's seat. Information indicating that the movement is that of the occupant seated in the driver's seat (occupant position information) is added to the movement information detected at this time.

  The microphone 17 is a microphone that collects conversation sounds and speech sounds between passengers. For example, a condenser microphone corresponds to the microphone 17. The collected sound signal from the microphone 17 is output to the microcomputer 11 as an analog amount. In the present embodiment, the voice input from the microphone 17 is subjected to command analysis by voice recognition processing by the microcomputer 11 to enable an operation by voice input. Between the microphone 17 and the microcomputer 11, for example, a band-pass filter for cutting to remove low-frequency and high-frequency components around the passenger's voice band is inserted. At the same time as the sound is detected by the microphone 17, the image sensor, which is one of the motion sensors 16, detects the movement of the passenger's mouth and identifies the passenger's seat from the position where the movement of the mouth in the image is detected. Then, motion information including the position information of the occupant is output.

  The display 18 is a liquid crystal display device, for example, and is connected to the microcomputer 11. A predetermined menu screen, a guidance screen, and an agent are displayed on the display 18 by data input from the microcomputer 11. A touch panel 15 is provided on the screen surface of the display 18, and images such as buttons and pictograms that enable a touch operation by an occupant are also displayed by the display 18.

  The speaker 19 is a speaker with an audio amplifier, for example, and is connected to the microcomputer 11. From the speaker 19, for example, a predetermined sound for informing the start and end of the navigation device 10, a synthesized voice accompanying route guidance, and these voice guidance sounds by the agent are output.

  Here, a method (first step) of detecting by the user identification unit 5 whether or not a body movement is generated in synchronization with the operation input timing will be described with reference to FIG. FIG. 3A is a characteristic diagram showing a change example of the body movement (movement near the shoulder) by the movement sensor 16 in response to the operation input of the touch panel 15. FIG. 3B is a characteristic diagram illustrating an example of a change in body movement (displacement of the chest) by the movement sensor 16 in response to voice input from the microphone 17.

  When the touch panel 15 is touched by the occupant, the microcomputer 11 receives the position information (operation information). When the position of the occupant's shoulder, arm, or the like changes with the operation, the motion sensor 16 detects the occupant movement information. Is entered. As described above, the movement information includes the position information of the occupant. In synchronization with the timing when position information (operation information) is input by the touch panel 15, that is, when the navigation device 10 is touched (operation timing), the movement information input from the motion sensor 16 includes movements of the shoulders and arms. In the case shown, the microcomputer 11 detects the synchronization between the operation timing and the timing when the body moves (operation timing) (see FIG. 3A). As a result, from the position information of the occupant included in the movement information, the user identifying unit 5 identifies which seat the occupant operating the navigation device 10 is.

  Further, when an occupant's voice is input from the microphone 17 to the microcomputer 11, the voice signal (operation information) is input, and when the body surface such as the chest or the neck is displaced in accordance with the speech, the motion sensor 16 Chest movement information is input. Therefore, the movement information input from the movement sensor 16 indicates the movement of the chest in synchronization with the timing when the audio signal (operation information) from the microphone 17 is input, that is, the operation timing when the navigation device 10 is operated by voice input. If so, the microcomputer 11 detects the synchronization between the operation timing and the operation timing (see FIG. 3B). As a result, the user identification unit 5 identifies which seat the occupant operating the navigation device 10 is. Normally, body surfaces such as the chest and neck are also displaced by breathing. While the displacement of the body surface due to respiration alone is periodic and steady, at the time of speech, such a steady displacement is changed and disturbed. Therefore, the movement of the body due to the utterance is determined from the displacement of the body surface due to respiration by capturing the change due to such disturbance.

  In this way, the body part that focuses on the movement is selected (filtered) according to the operated target (operation target). Specifically, when the touch panel is operated, the microcomputer 11 employs shoulder and arm movement information as the movement of interest, and excludes mouth and chest movement information. In addition, when an occupant's voice is input from the microphone 17, the microcomputer 11 adopts movement information of the mouth, chest, and neck as movements of interest, and excludes movement information of the shoulders and arms.

  In addition to the first stage of detecting the presence or absence of the movement of the body synchronized with the operation input timing, the user identification unit 5 based on one or more biological signals that can be acquired from the movement information, Individual identification is also performed (second stage). The body motion information detected by the motion sensor 16 includes information regarding the heart cycle and the body surface displacement accompanying the heart beat, in addition to the breathing cycle and body surface displacement of the chest and neck associated with breathing. Therefore, by storing these pieces of information as information based on biological signals in, for example, a database such as the storage device 12, the microcomputer 11 personally identifies the occupant who operated the navigation device. As a result, it is possible not only to identify which seat the passenger who has operated the navigation device 10 is, but also to identify the individual operator. That is, in the second-stage identification by the user identification unit 5, the operator can be identified at the individual level.

  Next, the information presentation process will be described with reference to FIGS. FIG. 4 illustrates a flowchart of information presentation processing executed by the microcomputer 11. FIG. 5 shows a flowchart of user identification processing which is a subroutine shown in FIG.

  This information presentation process is started after a predetermined initialization process or a navigation preparation process by the microcomputer 11 is executed after the navigation apparatus 10 is turned on. The microcomputer 11 first waits for input of operation information (S11, 13; NO). When there is input of operation information (S13; YES), user identification processing is performed. The user identification process is illustrated in FIG.

  In the user identification process shown in FIG. 5, the timing is first extracted (S21). As described above, this is a process of extracting the operation timing when the navigation device 10 is operated from the operation information (position information or audio signal) by the touch panel 15 or the microphone 17. Based on this operation timing, it is determined whether or not the movement indicated by the occupant movement data output from the motion sensor 16 is synchronized with the operation timing, that is, whether or not the operation timing and the operation timing are synchronized. (S23).

  If it is determined that the operation timing and the displacement timing are synchronized (S23; YES), it is specified which seat the passenger (occupant who operated the navigation device 10) is (S25). As described above, the motion information includes information (occupant position information) indicating which seat the occupant has detected motion. From which the occupant's position information identifies which seat the user is occupant. On the other hand, when it is not determined that both timings are synchronized (when it is determined that both timings are not synchronized) (S23; NO), it is assumed that the identification of the user is unsuccessful as shown in FIG. Terminate the process. If the identification of the user is unsuccessful (S23; NO), the navigation apparatus 10 also skips the “update of agent characteristic control value” (S17) of FIG. 4, and in step S18, Presentation information for a conventional unspecified user is generated.

  When the user can be identified (S25), the feature amount is extracted (S28). This is because the motion sensor 16 outputs the above-described physical feature quantities specific to the individual user (respiration cycle and body surface displacement accompanying breathing, and body surface displacement accompanying heartbeat and heartbeat). This is a process of extracting from the data. Accordingly, by searching the occupant data stored in the storage device 12 based on the extracted physical feature amount, it becomes possible to discriminate the user, that is, identify the individual user. The extracted user identification information is output to the agent characteristic control unit 6 by the identification information output process (S29), and the user identification process is terminated.

  When the user identification process ends, the process returns to the information presentation process shown in FIG. 3 again to update the agent characteristic control value (S17). In the update process of the agent characteristic control value, as described above, the agent corresponding to the user is specified based on the identification information output from the user identification unit 5, and the agent characteristic control value is converted into the motion information and the operation information. Based on this, a new control value for update is set and output to the presentation information output unit 8. The subsequent generation of the presentation information is performed by the presentation information generation unit 7 (S18). As described above, the presentation information is generated based on the operation information input from the operation input unit 3, the motion information input from the motion detection unit 4, and the identification information input from the user identification unit 5. The information is output to the presentation information output unit 8.

  Based on the new agent characteristic control value (S17) set in this way and the generated presentation information (S18), the presentation information is finally output (S19), and a series of this information presentation processing is completed. . The presentation information by the agent is as described in the description of the presentation information output unit 8 constituting the agent system 2.

  As described above, in the navigation device 10 in which the agent system 2 is mounted, the motion information output from the motion detection unit 4 (motion sensor 16) and the operation input unit 3 (touch panel 15 or microphone 17) are output. Based on the operation information, the user identification unit 5 (microcomputer 11) determines whether or not the timing when the occupant's body moves (operation timing) and the timing when the navigation device 10 is operated (operation timing) are synchronized. If they are synchronized, information (identification information) identifying which seat the passenger is in from the position information of the passenger included in the movement information is output to the agent characteristic control unit 6. . In this way, the user identification unit 5 can identify which occupant in the seat operated the navigation device 10 with a simple algorithm that compares the operation timing with the operation timing. The technique of the embodiment can identify a user with high accuracy while being a simple algorithm. Further, by improving the identification accuracy, the agent system 2 can generate appropriate presentation information by the presentation information generation unit 7 for the occupant (user) who operates the navigation device 10, and the agent characteristic control unit 6 and the presentation information output unit. 8 makes it possible to present accurate information. Therefore, the function and performance of the agent system 2 can be improved as a more friendly user interface. Furthermore, by providing the agent characteristic control unit 6 and the like with a function for accumulating and learning operation information and motion information for each identified occupant, the occupant (user) has a sense that the agent gains experience and grows. Can be given to. As a result, the occupant (user) 's attachment to the agent and a sense of familiarity are deepened, which contributes to an improvement in the acceptability of the presented information.

  Points to be noted regarding the example technology will be described. The operation input unit 3 corresponds to an example of an “operation time point detection unit”, and the user identification unit 5 corresponds to an example of an “identification determination unit”. The touch panel 15 or the microphone 17 corresponds to an example of an “operation time point detection unit”, the motion sensor 16 including an image sensor or a microwave Doppler sensor corresponds to an example of a “motion detection unit”, and the microcomputer 11 performs “identification determination”. This corresponds to an example of “part”. Furthermore, the navigation device 10 corresponds to an example of an “on-vehicle device”. The operation information corresponds to an example of “operation time point information”.

  The motion detection unit is not limited to the motion sensor 16 (image sensor or microwave Doppler sensor) described in the embodiment. As a simple one, an infrared sensor that detects the movement of the human body can be used, and a laser sensor can also be used.
