  2. Description of the Related Art Conventionally, as an in-vehicle electronic device that effectively prevents a drowsy driving, a device that outputs a predetermined content and awakens a driver when a nap is detected is known.

  For example, Patent Document 1 discloses a technique for acquiring biological information such as a driver's blink or heartbeat, and outputting a message prompting a break when the acquired biological information is abnormal.

  Further, in Patent Document 2, if the position of a restaurant is lost within 15 minutes or more in the past two hours, the driver estimates that the driver is after eating, increasing the risk, There has been disclosed a technique for performing an alarm process for outputting a warning sound and a warning message when the degree exceeds a reference value.

JP 2011-128823 A JP 2011-066551 A

  However, as in Patent Document 1, in order to acquire the driver's biological information, a special device such as a camera or a heart rate monitor is required. In addition, as in Patent Document 2, when the risk level is increased when it is estimated after eating, another configuration for increasing the risk level is required.

  In view of such a problem, it is an object to provide a content output system, a content distribution server, and a content output method capable of estimating a decrease in driver's attention with a simple configuration and appropriately stimulating the driver. .

The content output system of the present invention includes:
A content output unit that outputs designated content in a form that a driver of a mobile body can recognize through the five senses;
A memory that stores the location of the facility, the type of facility indicating whether or not the facility is a first facility for performing a specific activity, and facility information including a first reference stay time determined for each facility And
With reference to the facility information, it is determined that the state where the distance between the position of the first facility and the position where the moving body is stopped is within the first distance continues for the first reference stay time or longer of the first facility. And a designated content output control unit that instructs the content output unit to output the designated content a predetermined time after the moving body starts moving.

  The probability that the driver's attention will be reduced after a certain period of time after performing a specific activity such as eating, drinking, or exercising increases. According to the content output system of the present invention, the first facility for performing a specific activity If the distance between the position of the moving object and the position where the moving body has stopped for the first reference stay time of the first facility is determined to be within the first distance, the moving object moves after a predetermined time from the start of movement. The designated content is output in a form that the body driver can recognize through the five senses. Here, the first reference stay time is determined for each facility. This is because, for example, even if the activity is the same, the time taken for the activity is considered to be different for each facility.

  In other words, according to the content output system of the present invention, when there is a high probability that the driver of the mobile object performs a specific activity and the attention of the driver of the mobile object is reduced, It can stimulate the driver.

  As described above, according to the content output system of the present invention, it is possible to accurately estimate a decrease in the driver's attention with a simple configuration and to appropriately stimulate the driver.

In the content output system of the present invention,
The type of facility indicates whether the facility is a second facility that is different from the first facility or the first facility and is more frequently used than the first facility,
When the designated content output control unit determines that the distance between the position where the moving body stops and the position of the second facility is within the second distance, the designated content after a predetermined time from the start of movement. It is preferable that the content output unit is instructed to hold the output.

  When the moving body stops near the second facility that is different from the first facility and is used more frequently than the first facility, the driver of the moving body does not move to the first facility but to the second facility. The probability of staying is high, and even when a certain period of time has passed since the moving body started moving, the necessity of stimulating the driver of the moving body is low. According to the content output system having the configuration, when it is determined that the distance between the position of the second facility and the position where the moving body stops is within the second distance, the moving body starts moving. Since the content output unit is instructed to suspend output of the designated content after a predetermined time from the designated time, the designated content is not output based on this instruction.

  As a result, it is avoided that the driver of the moving body is uncomfortable due to the output of the specified content that is less necessary.

In the content output system of the present invention,
The type of the facility is different from the first facility or the first facility, and indicates whether the facility is a third facility where a specific work is performed on the mobile body,
The designated content output control unit determines that the state where the distance between the position of the third facility and the position where the moving body is stopped is within the third distance has continued for the first reference stay time or longer of the third facility. In such a case, the state where the distance between the position of the first facility and the position where the moving body stops is within a fourth distance that is larger than the first distance continues for the first reference stay time or longer of the first facility. When the determination result is affirmative, it is preferable to instruct the content output unit to output the designated content after a predetermined time from the start of the movement.

  When a specific work is performed on a moving object, the driver of the moving object is not expected to continue to perform the specific work on the moving object, but may move to a different location.

  According to the content output system having such a configuration, when a specific work on a moving object can be performed, a specific activity is performed at the first facility near the third facility, and the attention of the driver of the moving object is reduced. The driver of the moving object can be stimulated by the output of the designated content when the probability is high.

  Therefore, according to the content output system of the said structure, the fall of a driver's attention can be estimated with a simple structure, and a driver can be stimulated appropriately.

In the content output system of the configuration,
It is preferable that the designated content output control unit recognizes the working time of the moving body, and is set so that the fourth distance becomes intermittently or continuously longer as the working time is longer.

  According to the content output system having the configuration, the longer the work time is, the longer the fourth distance is set to be intermittently or continuously, so that the driver of the moving object is relatively far away because the work time is long. Even if the first facility is visited, the designated content is output after a predetermined time from the start of movement. Thereby, the driver of a moving body can be stimulated appropriately.

In the content output system of the present invention,
The facility information includes a second reference stay time determined for each facility,
The designated content output control unit is configured such that a state in which a distance between the position of the first facility and the position where the moving body is stopped is within a first distance is greater than a first reference stay time of the first facility. It is preferable not to instruct the content output unit to output the designated content after a predetermined time from the start of movement when it is determined that the duration has continued for the stay time or longer.

  For example, even if the moving object has been stopped for a long time near the first facility, sufficient time has passed so that the attention time is reduced when the staying time is viewed from the time of performing a specific activity such as eating or exercising. If so, the need to stimulate the driver of the moving body is assumed to be low.

  According to the content output system of the said structure, the state where the distance of the position of the said 1st facility and the position where the said mobile body stopped is less than 1st distance is larger than the 1st reference | standard stay time of the said 1st facility. If it is determined that it has continued for two or more reference stay times, the content output unit is instructed to suspend output of the designated content after a predetermined time from the start of movement. As a result, it is avoided that the driver of the moving body is uncomfortable due to unnecessary output of designated content.

In the content output system of the configuration,
The designated content output control unit determines that a state where the distance between the position of the first facility and the position where the moving body is stopped is within the first distance has continued for the second reference stay time or longer, and When the start time of the moving body is included in a predetermined time zone, it is preferable that the content output unit is instructed to output the designated content after a predetermined time since the moving body starts moving.

  Even if the user stays for a longer time than eating and drinking at the first facility, the driver of the mobile object is in the first facility when the start time of movement of the mobile object is included in a predetermined time zone such as when eating. There is a high probability of eating and drinking just before leaving. According to the content output system having such a configuration, when there is a high probability of eating or drinking just before leaving the first facility, the designated content is output after a predetermined time from the start of movement. Can be stimulated.

(Content output system)
The content output system shown in FIG. 1 includes a content distribution server 10 that can communicate with each other via a network, and a mobile unit 2 on which the content output device 20 is mounted. The moving body 2 is a vehicle, for example.

(Content distribution server)
The content distribution server 10 includes a server control unit 11, a server storage unit 12, and a server communication unit 13.

  Part or all of the computer constituting the content distribution server 10 may be configured by the components of the content output device 20. For example, a part or all of the content distribution server 10 may be configured by one or a plurality of content output devices 20 as mobile stations.

  The server control unit 11 is configured by a processor such as a CPU.

  The server control unit 11 functions as an information recognition unit 111 and a designated content output control unit 112 that perform arithmetic processing described later by executing a predetermined program.

  “Constructed” means that a constituent element of the present invention executes the assigned arithmetic processing means that an arithmetic processing unit such as a CPU constituting the constituent element requires information from a memory or recording medium such as a ROM or a RAM. In addition to this, it means that the software is read out and “programmed” or “designed” so as to execute arithmetic processing on the information according to the software. Each component may be configured by a common processor (arithmetic processing device), or each component may be configured by a plurality of processors capable of mutual communication.

  The server storage unit 12 includes a storage device such as a RAM, a ROM, or an HDD, and is configured to record various information. The server storage unit 12 is configured to be able to store and read data used in arithmetic processing by the server control unit 11.

  The server storage unit 12 stores content information C0, user information U0, and navigation information N0. The content information C0, the user information U0, and the navigation information N0 can be sequentially updated by arithmetic processing or communication with the outside.

  The content information C0 includes a content ID column C01, a tag column C02, and a title column C03 as a list of information of each content such as music content, news content, or video content, as shown in FIG. 2A.

  The content ID column C01 is a column that stores an ID for identifying content.

  The tag column C02 is a column for storing content tags. The content tag includes, for example, terms related to the preference of the driver D such as soccer, xx's composition and comics, and general terms such as an alarm.

  The title column C03 is a column that stores the title of the content.

  The content information C0 includes designated content C1 and non-designated content C2.

  The designated content C <b> 1 is content for stimulating the driver D, for example, content that conforms to the preference of the driver D or content such as a sleepiness alarm. The designated content C1 may be determined in advance, or may be dynamically determined based on the preference information U2 included in the user information U0 when a process described later is executed. In addition, it is guessed that the content according to the preference of the driver D is output, and the driver D's interest can be attracted and the driver D can be naturally awakened.

  For example, if there is information indicating that the driver D likes a team with soccer, the cheer song of that team may be output as the designated content C1. Further, if there is information that the composer likes the driver D, the song composed by the composer may be output as the designated content C1. The preference of the driver D is stored in preference information U2 described later.

  The non-designated content C2 is content other than the designated content C1.

  The user information U0 includes user identifier information U1 for specifying each driver D, preference information U2 indicating the preference of each driver D, base information U3 regarding the location of the driver D such as a workplace or home, and Mobile body information U4 including position information of the content output device 20 is included. The preference information U2, the base information U3, and the mobile body information U4 are stored in association with the user identifier information U1, respectively.

  The preference of each driver D is set at the time of user registration of the service of the content distribution server 10 of the driver D. In addition to or instead of this, the preference of the driver D may be estimated from the past operation history of the driver D.

  For example, if a content whose tag is soccer is frequently output by an operation of the driver D, it may be estimated that the driver D likes soccer. In addition, if the driver D stops the output while the content whose tag is soccer is output, it may be estimated that the driver D does not like soccer.

  In the base information U3, the location of the base is set at the time of user registration of the service of the content distribution server 10 of the driver D. In addition to or instead of this, a position where the moving body 2 stops at a certain number of times or at a certain frequency may be set as the position of the base.

  The mobile body information U4 is information received from the mobile body and is updated as needed according to communication with the mobile body.

  The navigation information N0 includes traffic information N1 indicating traffic conditions such as traffic congestion, map information N2 representing each road, each intersection, and each facility with links and nodes, and facility information N3.

  As shown in FIG. 2B, the facility information N3 includes a facility ID column N31, a type column N32, a position column N33, a first reference stay time column N34, and a second reference stay time column N35.

  The facility ID column N31 is a column that stores a facility ID for identifying a facility.

  The type column N32 is a column that stores types of facilities such as restaurants, gyms, commercial facilities, and amusement parks.

  The types of facilities are roughly classified into a first facility, a second facility, a third facility, and other facilities.

  The first facility is a facility for performing a specific activity, for example, a restaurant or a gym.

  Here, the specific activity is an activity that causes a reduction in attention after a predetermined time, and is, for example, eating or drinking or exercise.

  The second facility is a facility that is different from the first facility and that the driver D frequently visits. For example, the second facility is a base such as a home or a work place.

  The third facility is a facility that is different from both the first facility and the second facility and in which a specific operation is performed on the mobile body 2, for example, a gas station, a power supply facility, or a maintenance factory. Particular tasks can include charging, car washing and maintenance. In particular, it is preferable that the specific work is charging of energy such as charging, car washing, and maintenance in which the work time from the work start to the work end is long.

  The position column N33 is a column for storing the position of the facility on the map.

  For example, when the type of facility is the first facility that performs a specific activity, the first reference stay time column N34 stores a time that can be estimated as the time spent at the facility to perform the specific activity. Column.

  The time that can be estimated to have stayed at the facility to perform the specific activity is a time determined for each facility, for example, 15 minutes if the facility is a fast food restaurant, and the facility is a gym If so, 60 minutes.

  In addition, when the type of facility is the third facility where the specific work for the mobile body 2 is performed, the first reference staying time column N34 can be estimated as the time spent at the facility because the specific work is performed. It is a column that stores such time.

  The second reference staying time column N35 is a time at which it is estimated that sufficient time has passed so that the reduced attention after returning to the specific activity at the first facility has returned.

  The server communication unit 13 is configured to communicate with an external terminal such as the content output device 20 in accordance with a communication standard suitable for wireless communication at a long distance such as wired or WiFi (registered trademark).

(Moving body)

The sensor unit 28 is configured to output the acquired information to the content output device 20.

(Specified content output processing)
Next, the designated content output process will be described with reference to FIG.

  The output device control unit 21 recognizes information of various moving objects acquired from the sensor unit 28 (FIG. 3 / STEP 210).

  The output device control unit 21 transmits the information of the recognized moving body to the content distribution server 10 via the long-distance communication unit 232 (FIG. 3 / STEP 220).

  The information recognizing unit 111 determines whether or not information on the moving body is received from the content output device 20 via the server communication unit 13 (FIG. 3 / STEP 110).

  When the determination result is negative (FIG. 3 / STEP 110... NO), the information recognition unit 111 executes the process of FIG. 3 / STPE 110 again.

  If the determination result is affirmative (FIG. 3 / STEP 110... YES), the information recognition unit 111 stores the received information in addition to the mobile body information U4 together with the detection time or the reception time of the information in the mobile body. (FIG. 3 / STEP 120).

  The designated content output control unit 112 refers to the moving body information U4 to determine whether or not the moving body 2 has stayed at a certain place continuously for a certain time (for example, 5 minutes) (FIG. 3 / STEP 130). ). For example, the designated content output control unit 112 determines whether or not the time when the position of the moving body 2 is the same or substantially the same in FIG. In addition to or instead of this, for example, in FIG. 3 / STEP 130, the designated content output control unit 112 has a constant time from when the ignition switch of the moving body 2 is turned off to when the ignition switch is turned on. Judge whether it is more than time.

  When the determination result is negative (FIG. 3 / STEP 130... NO), the designated content output control unit 112 ends the current designated content output process and executes the next designated content output process.

  If the determination result is affirmative (FIG. 3 / STEP 130... YES), the designated content output control unit 112 executes a designated content output necessity determination process described later (FIG. 3 / STEP 140). Note that the designated content output control unit 112 recognizes the position where the moving body 2 has stayed for a predetermined time or more in FIG. 3 / STEP 130 as the stop position of the moving body 2.

  The designated content output control unit 112 determines whether or not the result of the designated content output necessity determination process needs to be output (FIG. 3 / STEP 150).

  If the determination result is negative (FIG. 3 / STEP 150... NO), the designated content output control unit 112 ends the current designated content output process and executes the next designated content output process.

  Note that if the designated content output control unit 112 ends the current designated content output processing without executing the processing of FIG. 3 / STEP 160 in the case of FIG. 3 / STEP 150. This is equivalent to “instructing the content output unit to hold output”. Alternatively, data indicating suspension of output of the designated content may be transmitted to the content output device 20 via the server communication unit 13.

  When the determination result is affirmative (FIG. 3 / STEP 150... YES), the designated content output control unit 112 transmits an instruction to output the designated content to the content output device 20 via the server communication unit 13 after a predetermined time. (FIG. 3 / STEP 160).

  Here, the predetermined time is a time when attention is reduced after a specific activity, and may be determined in advance, or may be determined for each facility or each facility type. In addition, the designated content output control unit 112 may designate the output mode such as increasing the output volume.

  Note that the processing of FIG. 3 / STEP 160 corresponds to the “designated content output control step” of the present invention.

  The output device control unit 21 determines whether or not an instruction to output the designated content has been received (FIG. 3 / STEP 230).

  When the determination result is negative (FIG. 3 / STEP 230... NO), the output device control unit 21 executes the process of FIG. 3 / STEP 210 again.

  When the determination result is affirmative (FIG. 3 / STEP 230... YES), the output device control unit 21 determines whether a predetermined time has elapsed and the previous content has ended (FIG. 3 / STEP 240). ).

  When the determination result is negative (FIG. 3 / STEP 240... NO), the output device control unit 21 executes the process of FIG. 3 / STEP 240 again.

  When the determination result is affirmative (FIG. 3 / STEP 240... YES), the output device control unit 21 outputs the designated content to the speaker 24 or the touch panel 25 in the designated output mode according to the instruction, thereby outputting the designated content. It outputs (FIG. 3 / STEP250).

  Thus, the designated content output process ends.

(Specified content output necessity determination process)
Next, the designated content output necessity determination process of FIG. 3 / STEP 140 will be described with reference to FIGS.

  As shown in FIGS. 5A to 5C, the designated content output control unit 112 has a first facility P1 within the first distance r1 and a second facility P2 within the second distance r2 from the stop position P0 of the moving body 2. Then, the third facility P3 within the third distance r3 is read (FIG. 4 / STEP 141).

  Here, the first distance r1, the second distance r2, and the third distance r3 are the upper limits of distances that may use the first facility P1, the second facility P2, and the third facility P3, respectively. The distance is such that it can arrive within a predetermined time (for example, within 5 minutes) from the stop position P0 of the moving body to each distance by walking. These distances can be different for each facility, and can be determined by experiments, for example. The first distance r1, the second distance r2, and the third distance r3 may be the same distance or different distances.

  The designated content output control unit 112 has read the second facility P2 within the second distance r2, in other words, the second facility P2 within the circle R2 having the radius r2 centered on the stop position P0 of the moving body 2. Is determined (FIG. 4 / STEP 142).

  In addition, instead of determining whether the linear distance between the stop position P0 of the mobile body 2 and the position of the facility is within a predetermined distance, the designated content output control unit 112 determines the facility from the stop position P0 of the mobile body 2 It may be determined whether or not the movement distance when the road (sidewalk) to the position is within a predetermined distance.

  When the determination result is affirmative (FIG. 4 / STEP142... YES), that is, as shown in FIG. 5A, when the second facility P2 exists in the circle R2, the designated content output control unit 112 It is determined that the specified content is not required to be output.

  Since the second facility P2 is a facility that is used more frequently than the first facility, as shown in FIG. 5A, even if the first facility P1 exists within the first distance r1 (within the circle R1). Driver D has a high probability of stopping at the second facility P2. In this case, since there is a high probability that the driver D is not performing a specific activity, the necessity of stimulating the driver D after a predetermined time from the start of the movement of the moving body 2 is low.

  When the determination result is negative (FIG. 4 / STEP142... NO), the designated content output control unit 112 determines that the distance between the stop position P of the mobile body 2 and the first facility P1 is within the first distance r1 and the mobile body. It is determined whether the second stop time is equal to or longer than the first reference stay time of the first facility P1 (FIG. 4 / STEP 143). The process of FIG. 4 / STEP 143 corresponds to the “determination step” of the present invention.

  When the determination result of FIG. 4 / STEP 143 is affirmative (FIG. 4 / STEP 143... YES), the designated content output control unit 112 proceeds to FIG. 4 / STEP 147.

  Here, when the determination result of FIG. 4 / STEP 143 is affirmative, as shown in FIG. 5B, there is no second facility P2 within the second distance r2, and the first within the first distance r1. This is a case where there is a facility P1 and the stop time of the moving body 2 is equal to or longer than the first reference stay time of the first facility P1. In such a case, it is highly likely that the driver D is performing a specific activity in the first facility P1.

  If the determination result in FIG. 4 / STEP 143 is negative (FIG. 4 / STEP 143... NO), the designated content output control unit 112 proceeds to FIG. 4 / STEP 144.

  The case where the determination result of FIG. 4 / STEP 143 is negative means that the moving body 2 is not included even if there is no first facility P1 within the first distance r1 or there is the first facility P1 within the first distance r1. This is a case where the stop time is less than the first reference stay time of the first facility P1. In such a case, there is a high probability that the first facility P1 does not perform a specific activity.

  The process may proceed to FIG. 4 / STEP 144 only when there is no first facility within the first distance r1.

  In FIG. 4 / STEP 144, the designated content output control unit 112 determines that the distance between the stop position P0 of the mobile body 2 and the third facility P3 is within the third distance r3 and the stop time of the mobile body 2 is the third stop of the third facility P3. It is judged whether it is more than 1 standard stay time.

  If the determination result is negative (FIG. 4 / STEP 144... NO), the designated content output control unit 112 determines that the output of the designated content is unnecessary.

  Supplementally, the case where the determination result of FIG. 4 / STEP 144 is negative is that the third facility P3 is not within the third distance r3 (within the circle R3) from the stop position P0 of the moving body 2, or the third facility P3. This is a case where the stop time of the mobile body 2 is less than the first reference stay time of the third facility P3 even if the mobile body 2 is within the third distance r3 from the stop position P0 of the mobile body 2.

  In such a case, it is highly probable that the driver D does not use the third facility, and consequently, the driver D does not use the first facility in the vicinity. For this reason, the necessity for stimulating the driver D after a predetermined time from the start of the movement of the moving body 2 is low.

  When the determination result is affirmative (FIG. 4 / STEP 144... YES), the designated content output control unit 112 sets the fourth distance r4 based on the first reference stay time of the third facility P3, and the fourth distance The facility information of the first facility P4 within r4 (within the circle R4) is read (FIG. 4 / STEP145).

  Here, the fourth distance r4 is a distance larger than both the first distance r1 and the third distance r3. The fourth distance r4 is set to a larger distance as the first reference stay time of the third facility P3 is longer. The fourth distance r4 is a distance (for example, several hundred meters to several kilometers) that has a high probability of moving on foot from the stop position P0 of the moving object.

  The case where the determination result in FIG. 4 / STEP 144 is a positive is that the third facility P3 is within the third distance r3 from the stop position P0 of the moving body 2 and the moving body 2 as shown in FIG. 5C. This is a case where the stop time is equal to or longer than the first reference stay time of the third facility P3. In such a case, the driver D has a high probability of using the third facility P3.

  The third facility P3 is a facility where a specific work is performed on the mobile body 2, but the driver D does not necessarily have to be present to perform the specific work on the mobile body 2. During a specific work on the moving body 2, the driver D may use the first facility P4 in the vicinity.

  In view of such a possibility, the designated content output control unit 112 reads information on the first facility P4 within the fourth distance r4.

  Further, as the specific work on the moving body 2 takes longer, the driver D may visit the first facility P4 at a longer distance. For this reason, the fourth distance r4 is set to a large distance intermittently or continuously as the first reference stay time of the third facility P3 is longer.

  The designated content output control unit 112 determines whether the distance between the stop position P0 of the mobile body 2 and the first facility P4 is within the fourth distance r4 and the stop time of the mobile body 2 is equal to or longer than the first reference stay time ( FIG. 4 / STEP 146). Here, in the first reference stay time of the first facility P4, the reciprocation time between the stop position P0 of the moving body 2 and the first facility P4, which is obtained from the distance from the stop position P0 to the first facility P4. May be added.

  If the determination result is negative (FIG. 4 / STEP 146... NO), the designated content output control unit 112 determines that the output of the designated content is unnecessary.

  Supplementally, when the determination result is negative, there is no first facility within the fourth distance r4 from the stop position P0 of the moving body 2, or the first facility P4 is the first position from the stop position P0 of the moving body 2. Even if it exists within 4 distance r4, it is a case where the stop time of the mobile body 2 is less than the first reference stay time of the first facility P4.

  In such a case, there is a high probability that the driver D does not use the first facility P4. For this reason, the necessity for stimulating the driver D after a predetermined time from the start of the movement of the moving body 2 is low.

  If the determination result of FIG. 4 / STEP 146 is affirmative (FIG. 4 / STEP 146... YES), the designated content output control unit 112 proceeds to FIG. 4 / STEP 147.

  Here, when the determination result of FIG. 4 / STEP 146 is affirmative, as shown in FIG. 5C, the first facility P4 is within the fourth distance r4, and the stop time of the moving body 2 is This is a case where it is equal to or longer than the first reference stay time of the first facility P4. In such a case, the driver D is highly likely to have performed a specific activity in the first facility P4.

  In FIG. 4 / STEP147, the designated content output control part 112 determines whether the stop time of the mobile body 2 is more than the 2nd reference stay time of a 1st facility.

  FIG. 4 / STEP 147 is a process executed when the probability that the driver D was using the first facility is high as described above.

  If the determination result is negative (FIG. 4 / STEP 147... NO), the designated content output control unit 112 determines that the designated content needs to be output.

  Supplementally, the case where the determination result of FIG. 4 / STEP 147 is negative is a case where the stop time of the moving body 2 is not less than the first reference stay time of the first facility and less than the second reference stay time. . In such a case, as shown in FIG. 6A, it is highly likely that the driver D has started shortly after performing a specific activity in the period t1 when the moving body 2 is stopped.

  In such a case, after a predetermined time T1 has passed since the start of the movement of the moving body 2, there is a possibility that the attention of the driver D is reduced due to performing a specific activity. For this reason, it is highly necessary to output designated content for stimulating the driver D.

  On the other hand, when the determination result of FIG. 4 / STEP 147 is affirmative, that is, when the stop time of the moving body 2 is equal to or longer than the second reference stay time of the first facility, as shown in FIG. D may have a specific activity during a part of the period t3 of the period t2 in which the moving body 2 is stopped. However, since the period t2 in which the moving body 2 is stopped is long, the driver D There is a high probability that attention has returned.

  In such a case, the necessity to output the designated content is low.

  However, when the first facility is a restaurant and the moving start time of the moving body 2 is included in a predetermined time zone such as a meal, the stop of the moving body 2 is ended as shown in FIG. 6C. There is a high probability that the driver D is eating and drinking just before. In such a case, it is highly necessary to output the designated content after a predetermined time T2 after the moving body 2 starts moving.

  For this reason, when the determination result of FIG. 4 / STEP 147 is affirmative (FIG. 4 / STEP 147... YES), the designated content output control unit 112 determines that the facility type is a restaurant and the movement start time of the mobile body 2 is predetermined. It is determined whether it is included in the time zone (FIG. 4 / STEP 148).

  When the determination result is affirmative (FIG. 4 / STEP 148... YES), the designated content output control unit 112 determines that the designated content needs to be output.

  If the determination result is negative (FIG. 4 / STEP 148... NO), the designated content output control unit 112 determines that it is not necessary to output the designated content.

  The specified content output necessity determination process is thus completed.

  The content output device may not be connected to a device such as the sensor unit 28 of the mobile body 2.

  For example, as shown in FIG. 7, the content output device 320 includes a GPS sensor 285 and a gyro sensor 286 (or speed sensor), and recognizes position information and speed information of the moving body 2 (content output device 20) from these. May be.

  In this case, the designated content output control unit 112 may recognize the stop position of the moving body 2 based on the position information and speed information received from the content output device 320 by the same determination method as described above. .

  In addition, as illustrated in FIG. 8, the output device control unit 421 may function as part or all of the designated content output control unit 211 by executing a predetermined program.
