Description

Information presentation device

[0001] The present invention relates to an information presentation device.

[0002] In recent years, technologies have been disclosed that diagnose a driver's driving behavior and notify the driver of the diagnosis results in order to raise the driver's awareness of safe driving. For example, one such technology is disclosed that acquires vehicle information while the vehicle is in motion and notifies the driver of a diagnosis result of the driving condition based on the acquired vehicle information in order to raise the driver's awareness of safe driving, eco-driving, etc. (See, for example, Patent Document 1).

[0003] JP 2010-39639 A

[0004] Driving behavior is a series of predictions, cognitions, judgments, and operations, and requires the simultaneous exercise of cognitive functions such as memory, planning, attention, and spatial awareness. Therefore, it is said that the act of driving a car itself has the effect of improving brain health, including cognitive functions. However, the above-mentioned technology only notifies the driver of the diagnosis results of driving behavior related to safe driving and eco-driving, which has the problem of not being able to increase the driver's motivation for brain activity training to improve cognitive functions through driving behavior.

[0005] Therefore, the present invention has been made in consideration of the above-mentioned problems, and aims to provide an information presentation device that presents information to a driver to increase motivation for brain activity training.

[0010] 1 to 13, an information presentation device according to an embodiment of the present invention will be described.

[0011] First Embodiment An information presentation device 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG.

[0012] 1, the information display device 1 according to this embodiment includes a controller 100 and a display unit 200. The controller 100 will be described later.

[0013] The display unit 200 is, for example, a display panel such as a liquid crystal panel or an organic EL panel, and displays information input from the controller 100. In this embodiment, the display unit 200 displays, for example, information related to the cognitive function stimulating behavior before driving begins, and information related to the number of times the cognitive function stimulating behavior has been performed after driving ends. The display unit 200 may be, for example, a display panel such as a meter provided in the vehicle. The display modes of the cognitive function stimulating behavior and the information displayed by the display unit 200 will be described later.

[0014] <Configuration of Controller 100> The controller 100 is configured to include one or more processors and one or more memories communicably connected to the one or more processors. As shown in Fig. 2, in this embodiment, the controller 100 is configured to include a processor 110 and a memory 120. The configuration of the processor 110 will be described later.

[0015] The memory 120 includes a read-only memory (ROM), a random access memory (RAM), etc. In this embodiment, the memory 120 stores, for example, a control program and various data input from the processor 110.

[0016] In this embodiment, the memory 120 is configured to include an execution count storage unit 121. The execution count storage unit 121 stores information regarding the number of times a predetermined cognitive function stimulating behavior has been executed. In this embodiment, the execution count storage unit 121 stores, for example, information regarding the number of times the cognitive function stimulating behavior has been executed input from the controller 100. Details of the information stored in the execution count storage unit 121 will be described later.

[0017] 2, the processor 110 includes a cognitive function stimulating behavior detection unit 111 and a control unit 112. Each unit of the processor 110 and the memory 120 inputs and outputs various types of information via a bus line BL.

[0018] The cognitive function stimulating behavior detection unit 111 detects a cognitive function stimulating behavior performed by the driver. In this embodiment, the cognitive function stimulating behavior detection unit 111 starts detecting a predetermined cognitive function stimulating behavior, for example, when a detection request is input from the control unit 112 (described later) via the bus line BL. The predetermined cognitive function stimulating behavior is a driving operation that places a load on the driver's brain activity. In this embodiment, examples of the predetermined cognitive function stimulating behavior include a right / left turn, an obstacle avoidance operation, a lane change operation, a narrow passageway passage, and a parking operation. In this embodiment, the cognitive function stimulating behavior detection unit 111 analyzes video information acquired from a camera 300 that captures images of the surroundings of the vehicle in which the information presentation device 1 is installed, and detects the execution of the cognitive function stimulating behavior. In this embodiment, for example, when the cognitive function stimulating behavior detection unit 111 detects the execution of a predetermined cognitive function stimulating behavior, the cognitive function stimulating behavior detection unit 111 outputs information about the type of the detected cognitive function stimulating behavior (information about the detected driving operation) to the control unit 112 (described later) via the bus line BL. In this embodiment, the cognitive function stimulating behavior detection unit 111 stops detecting the cognitive function stimulating behavior when a detection stop request is input from the control unit 112 (described later) via the bus line BL, for example.

[0019] In this embodiment, the control unit 112 controls the entire information presentation device 1 in accordance with a control program stored in the memory 120 .

[0020] The control unit 112 displays information about the cognitive function stimulating behavior on the display unit 200 before starting driving. In this embodiment, the control unit 112, for example, acquires on / off information about the vehicle ignition from a vehicle control unit (not shown), and outputs information about the cognitive function stimulating behavior to the display unit 200 when it detects that the ignition has changed from off to on. An example of the display mode of information that the control unit 112 displays on the display unit 200 will be described using FIG. 3 . The control unit 112 displays, for example, a comment such as "Driving behavior increases the load on your brain activity. We will count the number of times you perform a cognitive function stimulating behavior while driving. Let's perform brain activity training with the aim of achieving the target number of times," along with a predetermined target number of times the cognitive function stimulating behavior will be performed during the current drive, on the display unit 200.

[0021] The control unit 112 stores information regarding the number of times cognitive function stimulating behaviors were performed during a period from the start of driving to the end of driving, and information regarding the number of times cognitive function stimulating behaviors were performed during a period from the past until the end of driving, in the execution count memory unit 121. An example of information stored by the control unit 112 in the execution count memory unit 121 will be described using FIG. 4 . In this embodiment, the control unit 112 stores, for example, the number of times cognitive function stimulating behaviors were performed by the driver during a period from when the information presentation device 1 was installed in the vehicle to the present (the value of "cumulative execution count" in FIG. 4 ), and the number of times cognitive function stimulating behaviors were performed by the driver during a period from when the driver turned on the ignition to when the driver turned off the ignition (the value of "execution count" in FIG. 4 ), in the execution count memory unit 121. In this embodiment, the control unit 112, for example, acquires on / off information about the vehicle ignition from a vehicle control unit (not shown), and when it detects that the ignition has changed from off to on, resets the value of the "number of executions" in Fig. 4 (updates the "number of executions" in the information about the number of executions of the cognitive function stimulating behavior stored in the execution count storage unit 121 to 0). In this embodiment, the control unit 112 updates the values ​​of the "cumulative number of executions" and "number of executions" for each cognitive function stimulating behavior stored in the execution count storage unit 121 based on information about the type of cognitive function stimulating behavior acquired from the cognitive function stimulating behavior detection unit 111 via the bus line BL, for example.

[0022] After driving is completed, the control unit 112 causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior was performed. After driving is completed, the control unit 112 causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior was performed during the period from the start of driving to the end of driving, and information regarding the number of times the cognitive function stimulating behavior was performed during the period from the past until the end of driving. In this embodiment, the control unit 112, for example, acquires on / off information about the vehicle ignition from a vehicle control unit (not shown), and when it detects that the ignition has changed from on to off, acquires information stored in the execution count memory unit 121 (information regarding the number of times the cognitive function stimulating behavior was performed) and generates screen information to be displayed on the display unit 200. In this embodiment, the control unit 112 outputs, for example, the generated screen information to the display unit 200. An example of a display mode of information displayed on the display unit 200 by the control unit 112 will be described with reference to FIG. 5 . In this embodiment, the control unit 112 displays, for example, performance information for the current drive, such as the cumulative number of times performed, the number of times performed, the target number of times performed, and the judgment for each cognitive function stimulating behavior. In this embodiment, the control unit 112 displays, for example, a graph of the degree of goal achievement, and visualizes and displays the degree of goal achievement. In this embodiment, the control unit 112 displays, for example, a comment on the display unit 200, such as "This is the number of times cognitive function stimulating behaviors were performed for the current drive. The target number of times for four out of six items was achieved. Let's continue brain activity training at this pace."

[0023] The control unit 112 further causes the display unit 200 to display information about the cognitive function stimulating behavior and information about the number of times the cognitive function stimulating behavior has been performed based on an instruction from the driver. In this embodiment, the control unit 112 detects the driver's instruction based on, for example, a sensor output from a touch panel (not shown) that is integrally configured with the display unit 200. In this embodiment, when the control unit 112 detects, for example, a touch operation requesting the display of information about the cognitive function stimulating behavior, the control unit 112 causes the display unit 200 to display information about the cognitive function stimulating behavior and the target number of times the cognitive function stimulating behavior has been performed, as shown in FIG. 3 . In this embodiment, when the control unit 112 detects, for example, a touch operation requesting the display of information about the number of times the cognitive function stimulating behavior has been performed, the control unit 112 obtains the number of times the cognitive function stimulating behavior has been performed at that time from the performance count memory unit 121, and causes the display unit 200 to display the number of times the cognitive function stimulating behavior has been performed and the target number of times the cognitive function stimulating behavior has been performed.

[0024] <Processing Flow of Control Unit 112> The processing flow of the control unit 112 of the information presentation device 1 will be described with reference to FIG.

[0025] The control unit 112 determines whether the vehicle ignition has changed from off to on (step S110). If the control unit 112 determines that the ignition has not changed from off to on ("NO" in step S110), it returns the process to a standby state. If the control unit 112 determines that the ignition has changed from off to on ("YES" in step S110), it transitions the process to step S120.

[0026] The control unit 112 causes the display unit 200 to display information related to the cognitive function stimulating behavior (step S120), and then causes the process to proceed to step S130.

[0027] The control unit 112 causes the cognitive function stimulating behavior detection unit 111 to detect a cognitive function stimulating behavior (step S130), and then causes the process to proceed to step S140.

[0028] The control unit 112 updates the information regarding the number of times the cognitive function stimulating behavior has been performed stored in the number of times memory unit 121 based on the information regarding the type of cognitive function stimulating behavior obtained from the cognitive function stimulating behavior detection unit 111 (step S140), and transitions the processing to step S150.

[0029] The control unit 112 determines whether the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed (step S150). If the control unit 112 determines, for example, based on the sensor output of a touch panel (not shown), that the driver has not requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("NO" in step S150), the control unit 112 proceeds to step S170. If the control unit 112 determines, for example, based on the sensor output of a touch panel (not shown), that the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("YES" in step S150), the control unit 112 proceeds to step S160.

[0030] In accordance with an instruction from the driver, the control unit 112 causes the display unit 200 to display information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed (step S160), and then proceeds to step S170.

[0031] The control unit 112 determines whether the vehicle ignition has changed from on to off (step S170). If the control unit 112 determines that the ignition has not changed from on to off ("NO" in step S170), the control unit 112 returns the process to step S130 and continues the process. If the control unit 112 determines that the ignition has changed from off to on ("YES" in step S170), the control unit 112 proceeds to step S180.

[0032] The control unit 112 causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior has been performed (step S180), and ends the process.

[0033] <Actions and Effects> As described above, the information presentation device 1 according to the present embodiment includes a cognitive function stimulating behavior detection unit 111 that detects a predetermined cognitive function stimulating behavior, an execution count memory unit 121 that stores information regarding the number of times the predetermined cognitive function stimulating behavior has been performed, and a control unit 112 that causes the display unit 200 to display information regarding the cognitive function stimulating behavior before driving begins and causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior has been performed after driving ends. In other words, when the driver starts driving a vehicle, the control unit 112 of the information presentation device 1 causes the display unit 200 to display information regarding the driving behavior (cognitive function stimulating behavior) that serves as brain activity training. When the driver starts driving, the control unit 112 of the information presentation device 1 displays on the display unit 200 a comment such as, "Driving increases the load on your brain activity. We will count the number of cognitive function stimulating behaviors performed while driving. Let's train your brain activity while keeping in mind the target number of times." Specific examples of driving behaviors (cognitive function stimulating behaviors) that train brain activity (e.g., turning right or left, avoiding obstacles, changing lanes, navigating narrow roads, parking, etc.) are displayed. This allows the driver to recognize that driving can train brain activity. Before starting driving, the control unit 112 of the information presentation device 1 displays on the display unit 200 a target number of times the cognitive function stimulating behaviors are performed. This allows the information presentation device 1 to increase the driver's motivation for brain activity training. After finishing driving, the information presentation device 1 displays on the display unit 200 a comment such as, "This is the number of cognitive function stimulating behaviors performed during this drive. You have achieved the target number of times for four out of six items. Keep up the good work and continue your brain activity training." This also displays information regarding the number of times the cognitive function stimulating behaviors are performed. In other words, the degree of achievement relative to the target value is visualized and displayed, allowing the driver to easily recognize the degree of achievement, thereby increasing the driver's motivation for brain activity training.

[0034] After driving ends, the display unit 200 of the information display device 1 according to this embodiment displays information regarding the number of cognitive function stimulating behaviors performed during the period from the start of driving to the end of driving, and information regarding the number of cognitive function stimulating behaviors performed during the period from the past until the end of driving. That is, the control unit 112 of the information display device 1 causes the display unit 200 to display information regarding the cumulative number of cognitive function stimulating behaviors performed from the past, and information regarding the cumulative number of cognitive function stimulating behaviors performed during the current drive. In this way, the information display device 1 displays not only information regarding the number of cognitive function stimulating behaviors performed during the current drive, but also information regarding the cumulative number of cognitive function stimulating behaviors performed from the past, thereby increasing the driver's motivation for brain activity training.

[0035] When the number of cognitive function stimulating behaviors performed reaches a predetermined target number, the display unit 200 of the information display device 1 according to this embodiment displays information indicating that the target number has been reached. In other words, the information display device 1 notifies the driver of the degree of achievement of the target number of cognitive function stimulating behaviors presented before the start of driving. For example, when driving ends, the information display device 1 displays a comment such as, "This is the number of cognitive function stimulating behaviors performed during this drive. The target number of times for four out of six behaviors has been achieved. Let's keep up the brain activity training at this pace." This allows the information display device 1 to display the degree of achievement of the target value to the driver, thereby increasing the driver's motivation for brain activity training.

[0036] The control unit 112 of the information presentation device 1 according to this embodiment further displays information about the cognitive function stimulating behavior and information about the number of times the cognitive function stimulating behavior has been performed on the display unit 200 based on instructions from the driver. That is, for example, if the driver wants to know the number of times the cognitive function stimulating behavior has been performed while driving, the driver can operate a touch panel (not shown) or the like to display information about the number of times the cognitive function stimulating behavior has been performed on the display unit 200. This allows the driver to obtain information about the cognitive function stimulating behavior and information about the number of times the cognitive function stimulating behavior has been performed at a desired timing. For example, the driver can obtain information about the target number of times / number of times the cognitive function stimulating behavior has been performed even while driving, allowing the driver to perform motivated brain activity training aimed at achieving their goal.

[0037] Second Embodiment An information presentation device 1A according to an embodiment of the present invention will be described with reference to Figures 7 to 10. Note that components with the same reference numerals as those in the first embodiment have similar functions, and therefore detailed descriptions thereof will be omitted.

[0038] <Configuration of Information Presentation Device 1A> As shown in FIG. 7, the information presentation device 1A according to this embodiment includes a controller 100A and a display unit 200.

[0039] <Configuration of Controller 100A> The controller 100A is configured to include one or more processors and one or more memories communicably connected to the one or more processors. As shown in Fig. 8, in this embodiment, the controller 100A is configured to include a processor 110A and a memory 120A. The configuration of the processor 110A will be described later.

[0040] The memory 120A is configured to include a ROM, a RAM, etc. (not shown). In this embodiment, the memory 120A stores, for example, a control program and various data input from the processor 110A. In this embodiment, the memory 120A pre-stores, for example, driver information linking the name, facial features, and age of a person who may drive a vehicle in which the information presentation device 1A is installed.

[0041] In this embodiment, the memory 120A includes an execution count storage unit 121A. The execution count storage unit 121A stores information regarding the number of times a predetermined cognitive function stimulating behavior has been performed for each driver. In this embodiment, the execution count storage unit 121A stores information regarding the number of times the cognitive function stimulating behavior has been performed for each driver, which is input from the controller 100A, for example.

[0042] <Configuration of Processor 110A> As shown in FIG. 8, the processor 110A includes a cognitive function stimulating behavior detection unit 111, a control unit 112A, and an identification unit 113.

[0043] The identification unit 113 identifies the driver. In this embodiment, when an identification request is input from a control unit 112A (described later) via the bus line BL, the identification unit 113 identifies the individual driver based on video information acquired from a camera 400 that captures an image of the driver of the vehicle in which the information presentation device 1A is installed and driver information pre-stored in the memory 120A. In this embodiment, the identification unit 113 outputs the name and age of the identified person to the control unit 112A (described later) via the bus line BL, for example. Since the identification unit 113 only needs to be able to identify the individual driver, for example, if a driver monitoring system is installed in the vehicle, the identification unit 113 may identify the driver based on information acquired from the driver monitoring system.

[0044] In this embodiment, the control unit 112A controls the entire information presentation device 1A in accordance with a control program stored in the memory 120A. In this embodiment, the control unit 112A, for example, acquires on / off information of the vehicle ignition from a vehicle control unit (not shown), and when it detects that the ignition has changed from off to on, outputs a detection request to the cognitive function stimulating behavior detection unit 111 and an identification request to the identification unit 113 via the bus line BL.

[0045] The control unit 112A stores information regarding the number of times the cognitive function stimulating behavior has been performed in the behavior count storage unit 121A for each driver identified by the identification unit 113. As shown in Fig. 9 , in this embodiment, the control unit 112A associates, for example, the driver's name acquired from the identification unit 113 with information regarding the number of times the cognitive function stimulating behavior has been performed and stores the information in the behavior count storage unit 121A. In this embodiment, for example, if the driver's name acquired from the identification unit 113 is "A," the control unit 112A updates the information regarding the number of times the cognitive function stimulating behavior has been performed that is associated with the name "A" based on the type of cognitive function stimulating behavior acquired from the cognitive function stimulating behavior detection unit 111.

[0046] In this embodiment, the control unit 112A, for example, acquires on / off information about the vehicle ignition from a vehicle control unit (not shown), and when it detects that the ignition has changed from off to on, outputs information about the cognitive function stimulating behavior to the display unit 200. In this embodiment, the control unit 112A causes the display unit 200 to display, for example, a comment such as "Driving behavior increases the load on your brain activity. We will count the number of times you perform a cognitive function stimulating behavior while driving. Let's perform brain activity training with the aim of reaching the target number of times," as well as a target number of times of the cognitive function stimulating behavior determined based on the age of the driver identified by the identification unit 113. Note that the display format displayed by the control unit 112A on the display unit 200 is the same as in the first embodiment, and therefore detailed description thereof will be omitted.

[0047] <Processing Flow of Control Unit 112A> A processing flow of the control unit 112A of the information presentation device 1A will be described with reference to FIG.

[0048] The control unit 112A determines whether the vehicle ignition has changed from off to on (step S110). If the control unit 112A determines that the ignition has not changed from off to on ("NO" in step S110), it returns the process to a standby state. If the control unit 112A determines that the ignition has changed from off to on ("YES" in step S110), it transitions the process to step S210.

[0049] Control unit 112A causes identification unit 113 to identify the driver (step S210), and causes the process to proceed to step S120.

[0050] The control unit 112A causes the display unit 200 to display information related to the cognitive function stimulating behavior (step S120), and moves the process to step S130.

[0051] The control unit 112A causes the cognitive function stimulating behavior detection unit 111 to detect a cognitive function stimulating behavior (step S130), and then causes the process to proceed to step S220.

[0052] Based on information regarding the type of cognitive function stimulating behavior obtained from the cognitive function stimulating behavior detection unit 111, the control unit 112A updates information regarding the number of times the cognitive function stimulating behavior associated with the driver identified in step S210 has been performed (step S220), and transitions processing to step S150.

[0053] The control unit 112A determines whether the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed (step S150). If the control unit 112A determines, for example, based on the sensor output of a touch panel (not shown), that the driver has not requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("NO" in step S150), the control unit 112A proceeds to step S170. If the control unit 112A determines, for example, based on the sensor output of a touch panel (not shown), that the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("YES" in step S150), the control unit 112A proceeds to step S160.

[0054] In accordance with an instruction from the driver, control unit 112A causes display unit 200 to display information related to the cognitive function stimulating behavior / information related to the number of times the cognitive function stimulating behavior has been performed (step S160), and then proceeds to step S170.

[0055] The control unit 112A determines whether the vehicle ignition has changed from on to off (step S170). If the control unit 112A determines that the ignition has not changed from on to off ("NO" in step S170), the control unit 112A returns the process to step S130 and continues the process. If the control unit 112A determines that the ignition has changed from off to on ("YES" in step S170), the control unit 112A proceeds to step S180.

[0056] The control unit 112A causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior has been performed (step S180), and ends the process.

[0057] <Actions and Effects> As described above, the information presentation device 1A according to this embodiment includes an identification unit 113 that identifies the driver, and the execution count memory unit 121A stores information regarding the number of times the cognitive function stimulating behavior has been performed for each driver. In other words, since multiple people may drive a vehicle in which the information presentation device 1A is installed, the information presentation device 1A identifies each individual driver and stores information regarding the number of times the cognitive function stimulating behavior has been performed for each driver. This allows the information presentation device 1A to display the number of times the cognitive function stimulating behavior has been performed (cumulative execution count) for each driver. Because the driver is provided with information related to themselves, they can be motivated to engage in brain activity training.

[0058] The information presentation device 1A according to this embodiment determines a target value for the number of times a cognitive function stimulating behavior is to be performed based on the driver's age identified by the identification unit 113. This makes it possible to present to the driver a target value for brain activity training that is suited to the driver's age. Because an excessive target value is not set, the driver can be motivated to engage in brain activity training.

[0059] Third Embodiment An information presentation device 1B according to an embodiment of the present invention will be described with reference to Fig. 11 to Fig. 13. Note that components with the same reference numerals as those in the first embodiment have similar functions, and therefore detailed descriptions thereof will be omitted.

[0060] <Configuration of Information Display Apparatus 1B> As shown in FIG. 11 , the information display apparatus 1B according to this embodiment includes a controller 100B, a display unit 200, and a communication unit 500.

[0061] In this embodiment, the communication unit 500 is, for example, a known wireless communication module, and functions as an interface for communicating with a mobile terminal 600 carried by the driver connected to the network N. In this embodiment, the communication unit 500 transmits information regarding the number of times the cognitive function stimulating behavior has been performed to the mobile terminal 600 under the control of, for example, the controller 100B. An example of the network N is the Internet. The mobile terminal 600 is, for example, a mobile terminal carried by the driver, and examples thereof include a smartphone and a tablet.

[0062] <Configuration of Controller 100B> The controller 100B is configured to include one or more processors and one or more memories communicably connected to the one or more processors. As shown in Fig. 12, in this embodiment, the controller 100B is configured to include a processor 110B and a memory 120B.

[0063] 12, the processor 110B is configured to include a cognitive function stimulating behavior detection unit 111 and a control unit 112B. Each unit of the processor 110B and the memory 120B input and output various types of information via a bus line BL.

[0064] The memory 120B is configured to include a ROM, a RAM, etc. (not shown). In this embodiment, the memory 120B stores, for example, a control program and various data input from the processor 110B. In this embodiment, the memory 120B stores, in advance, information (e.g., an email address) necessary for transmitting information to the mobile terminal 600.

[0065] The control unit 112B transmits information regarding the number of times the cognitive function stimulating behavior has been performed to the mobile terminal 600 carried by the driver. In this embodiment, the control unit 112B, for example, acquires on / off information about the vehicle ignition from a vehicle control unit (not shown), and when it detects that the ignition has changed from on to off, acquires information regarding the number of times the cognitive function stimulating behavior has been performed from the execution count memory unit 121 via the bus line BL. In this embodiment, the control unit 112B transmits the acquired information regarding the number of times the cognitive function stimulating behavior has been performed to the mobile terminal 600, for example, via the communication unit 500.

[0066] <Processing Flow of Control Unit 112B> A processing flow of the control unit 112B of the information presentation apparatus 1B will be described with reference to FIG.

[0067] The control unit 112B determines whether the vehicle ignition has changed from off to on (step S110). If the control unit 112B determines that the ignition has not changed from off to on ("NO" in step S110), it returns the process to a standby state. If the control unit 112B determines that the ignition has changed from off to on ("YES" in step S110), it transitions the process to step S120.

[0068] The control unit 112B causes the display unit 200 to display information related to the cognitive function stimulating behavior (step S120), and moves the process to step S130.

[0069] The control unit 112B causes the cognitive function stimulating behavior detection unit 111 to detect a cognitive function stimulating behavior (step S130), and then causes the process to proceed to step S140.

[0070] The control unit 112B updates the information regarding the number of times the cognitive function stimulating behavior has been performed stored in the number of times memory unit 121 based on the information regarding the type of cognitive function stimulating behavior obtained from the cognitive function stimulating behavior detection unit 111 (step S140), and transitions the processing to step S150.

[0071] The control unit 112B determines whether the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed (step S150). If the control unit 112B determines, for example, based on the sensor output of a touch panel (not shown), that the driver has not requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("NO" in step S150), the control unit 112B proceeds to step S170. If the control unit 112B determines, for example, based on the sensor output of a touch panel (not shown), that the driver has requested the display of information regarding the cognitive function stimulating behavior / information regarding the number of times the cognitive function stimulating behavior has been performed ("YES" in step S150), the control unit 112B proceeds to step S160.

[0072] Control unit 112B, in accordance with an instruction from the driver, causes display unit 200 to display information relating to the cognitive function stimulating behavior / information relating to the number of times the cognitive function stimulating behavior has been performed (step S160), and then proceeds to step S170.

[0073] The control unit 112B determines whether the vehicle ignition has changed from on to off (step S170). If the control unit 112B determines that the ignition has not changed from on to off ("NO" in step S170), the control unit 112B returns the process to step S130 and continues the process. If the control unit 112B determines that the ignition has changed from off to on ("YES" in step S170), the control unit 112B proceeds to step S180.

[0074] The control unit 112B causes the display unit 200 to display information regarding the number of times the cognitive function stimulating behavior has been performed (step S180), and moves the process to step S310.

[0075] The control unit 112B causes the communication unit 500 to transmit information regarding the number of times the cognitive function stimulating behavior has been performed to the mobile terminal 600 carried by the driver (step S310), and ends the process.

[0076] <Actions and Effects> As described above, the information presentation device 1B according to this embodiment includes a communication unit 500 that transmits information regarding the number of times the cognitive function stimulating behavior has been performed to the driver's mobile device 600. When the information presentation device 1B confirms that driving has ended, it transmits information regarding the number of times the cognitive function stimulating behavior has been performed, which is stored in the performance count storage unit 121, to the mobile device 600 carried by the driver. In other words, even if the driver has left the vehicle, the driver can check the information regarding the number of times the cognitive function stimulating behavior has been performed at any time by operating the mobile device 600.

[0077] <Variation 1> The program for the processing of the information presentation device 1 described above may be executed, for example, in a processor and memory of a navigation device provided in a vehicle, and information regarding the number of times the cognitive function stimulating behavior has been performed may be displayed on a display panel of the navigation device. For example, when the navigation device determines that a destination has been set by the driver, it displays information regarding the cognitive function stimulating behavior and a target number of times the cognitive function stimulating behavior has been performed. For example, the navigation device determines the target number of times the cognitive function stimulating behavior has been performed based on information such as the distance traveled from the current location to the destination and the travel route. For example, when the navigation device determines that the destination set by the driver has been reached, it displays information regarding the number of times the cognitive function stimulating behavior has been performed during the period from the departure point to the destination and information regarding the number of times the cognitive function stimulating behavior has been performed during the period from the past to the arrival at the destination. For example, when the navigation device determines that the vehicle is traveling along a route from the departure point to the destination, it displays a target number of times the cognitive function stimulating behavior has been performed and the number of times the cognitive function stimulating behavior has been performed while traveling along the route. This allows the navigation device to make the driver aware of their progress toward the goal, thereby increasing their motivation for brain activity training.

[0078] <Variation 2> The cognitive function stimulating behavior detection unit 111 described above detects vehicle behavior (turning right or left, changing lanes, etc.) as cognitive function stimulating behavior, but it may also detect, for example, the driver's vehicle operations (steering operation, accelerator pedal operation, brake pedal operation, wiper operation, etc.) as cognitive function stimulating behavior.

[0079] Although the information presentation devices 1, 1A, and 1B described above present the driver with information regarding the number of times a cognitive function stimulating behavior was performed, they may also display, for example, location information, weather information, traffic conditions, and video information about the area around the vehicle when the cognitive function stimulating behavior was performed, allowing the driver to recall what it was like when the cognitive function stimulating behavior was performed.

[0080] <Modification 4> When the above-described information presentation devices 1, 1A, and 1B display information regarding the number of times the cognitive function stimulating behavior has been performed, they may also simultaneously display, for example, a character that grows based on the cumulative number of times the cognitive function stimulating behavior has been performed, thereby further increasing the driver's motivation for brain activity training.

[0081] <Variation 5> Although the information presentation device 1B described above transmits information regarding the number of times the cognitive function stimulating behavior has been performed to the mobile device 600, the information regarding the number of times the cognitive function stimulating behavior has been performed may also be stored in a server connected to the network N. The driver may, for example, install a dedicated application program for checking information regarding the number of times the cognitive function stimulating behavior has been performed on the mobile device 600, and check the information regarding the number of times the cognitive function stimulating behavior has been performed that has been acquired from the server. This allows the driver to check the information regarding the number of times the cognitive function stimulating behavior has been performed regardless of location or time.

[0082] <Variation 6> The information presentation devices 1, 1A, and 1B described above display the cumulative number of executions, the number of executions, etc. for each cognitive function stimulating behavior on the display unit 200, but for example, the number of executions per unit time, etc. may also be displayed. The information presentation devices 1, 1A, and 1B may further display, for example, the cumulative driving time, cumulative driving time, cumulative driving distance, etc. since the start of brain activity training. In this way, the information presentation devices 1, 1A, and 1B present the driver with information regarding the continuity of brain activity training, thereby increasing the driver's motivation for brain activity training.

[0083] <Variation 7> The driver may be allowed to arbitrarily set a target value for the number of times the cognitive function stimulating behavior is to be performed, which is set by the above-described information presentation devices 1, 1A, and 1B. This allows the driver to set a higher target, thereby increasing the driver's motivation for brain activity training.

[0084] The information presentation device 1 of the present invention can be realized by recording the processing of the cognitive function stimulating behavior detection unit 111 and the control unit 112 described above on a recording medium readable by a computer system, and loading and executing the program recorded on this recording medium into memory. The computer system here includes hardware such as an OS and peripheral devices.

[0085] The above computer system also includes a homepage providing environment (or display environment) if it utilizes a WWW (World Wide Web) system. The above program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by transmission waves in the transmission medium. The transmission medium for transmitting the above program refers to a medium having the function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.

[0086] The above program may be for realizing some of the above functions, or may be a so-called differential file (differential program) that can realize the above functions in combination with a program already recorded in the computer system.
