  The piezoelectric element 25b uses a piezoelectric element, for example. The piezoelectric element 25b has a function of instantaneously changing the internal volume of the injection tank 25a by the piezoelectric effect based on the voltage applied by the fragrance injection control unit 27 and injecting the stored fragrance 26.

The information presentation apparatus 100 is configured as described above. Next, a procedure example of navigation processing using the information presentation apparatus 100 will be described with reference to FIGS.
FIG. 5 is a flowchart illustrating a procedure example of navigation processing using the information presentation apparatus 100.

  First, in step S1, the arithmetic control unit 19 determines whether or not a power switch (not shown) that is a part of the operation switch unit 17 is turned on. The arithmetic control unit 19 waits until the power switch is turned on, and executes step S2 when the power switch is turned on.

  In step S <b> 2, the arithmetic control unit 19 determines whether or not the destination is set using a destination setting button that is a part of the operation switch unit 17. The arithmetic control unit 19 waits until the destination is set, and executes step S3 when the destination is set.

  In step S3, the arithmetic control unit 19 uses the route search function and the guidance function using the map data, searches for the route from the current position to the destination, and guides the user according to the guidance route as the search result. Generate guidance information.

  Next, in step S4, the arithmetic control unit 19 instructs the user to walk so as to reach the destination based on the guidance information. Specifically, based on this guidance information, the arithmetic control unit 19 causes the user to be presented with information on fragrance by injecting fragrance into at least one of the left fragrance emitting unit 25L and the right fragrance emitting unit 25R. To the destination.

  Next, in step S5, the arithmetic control unit 19 determines whether or not the current position of the user has reached the route branch point while guiding the user by fragrance injection. When the current position of the user has reached this route branch point, the arithmetic control unit 19 executes a guide injection process described later, whereas when the current position of the user has not reached this route branch point, It is determined whether or not the destination has been reached. In the present embodiment, in this guided injection process, the calculation control unit 19 executes step S11 described later.

  The arithmetic control unit 19 executes the above-described step S5 when the user's current position has not reached the vicinity of the destination, while performs step S7 when the user's current position has reached the vicinity of the destination. Execute. In this step S7, the arithmetic control unit 19 causes a predetermined type or a predetermined pattern of aroma indicating that the user has arrived near the destination from at least one of the left aroma emitting unit 25L and the right aroma emitting unit 25R.

  On the other hand, if the user's current position is in the vicinity of the route branch point in step S5, the arithmetic control unit 19 executes the following guided injection process. In this guide injection process, for example, the following step S11 is executed. The calculation control part 19 will perform step S6 mentioned above, if step S11 is performed.

<Induction injection processing in the first embodiment>
In step S11, the arithmetic control unit 19 causes the fragrance for guidance to be ejected to at least one of the left fragrance emitting unit 25L and the right fragrance ejecting unit 25R based on the guidance information described above.

  Here, in each embodiment, such a fragrance for guidance is emitted from both the left fragrance ejection unit 25L and the right fragrance ejection unit 25R when the user is traveling on a straight road along the guidance route. The fragrance emitted from the left fragrance emitting portion 25L or the right fragrance emitting portion 25R is shown depending on whether it should turn left or right when it reaches the vicinity of the route branch point in the middle of the guide route. When such a guiding fragrance is ejected from the information presentation device 100 to the user, the user can recognize the direction in which the fragrance for guidance should travel by olfaction.

<When the user moves further>
FIG. 6 is a flowchart illustrating a procedure example of navigation processing using the information presentation apparatus 100. FIG. 6 shows an example in which the user further moves by the navigation processing shown in FIG. In the following description, the description of the navigation process shown in FIG. 6 that is substantially the same as the navigation process shown in FIG. 5 will be omitted, and a different guide injection process will be described.

<Induction injection processing>
First, in step S10, the arithmetic control unit 19 controls the GPS receiver 10 to detect the current position again, and determines whether or not the new current position substantially matches the latest current position stored in the storage unit 13. to decide.

  The arithmetic control unit 19 executes step S6 described above when these current positions match, and executes step S11 described above when these current positions do not match. That is, in this step S11, as described above, the arithmetic control unit 19 causes the fragrance for guidance to be ejected to at least one of the left fragrance ejection unit 25L and the right fragrance ejection unit 25R based on the guidance information.

<If you are off the guide route>
In addition, when the user deviates from the guidance route, the information control apparatus 19 executes the above-described step S3 and searches again for a new route from the current position deviating from the guidance route to the destination. . In this case, the arithmetic control unit 19 controls at least one of the left fragrance emitting unit 25L and the right fragrance emitting unit 25R according to the guidance content based on the new search result, and causes the user to emit the guiding fragrance.

  The information presentation apparatus 100 in the above embodiment includes a first fragrance emitting unit 25L that emits a fragrance from the first direction toward the user (left fragrance emitting unit), and a first fragrance that emits the fragrance from the second direction toward the user. 2 aroma injection means 25R (right aroma injection section), current position detection means 10 for detecting the current position (GPS receiver), destination setting means 17 for setting a desired destination (operation switch section), The user has a control means 19 for controlling the fragrance injection by at least one of the first fragrance injection means 25L and the second fragrance injection means 25R according to the direction to be guided to the destination.

  In this way, the user specifies the fragrance emission direction by the sense of smell because the fragrance is emitted from the first fragrance emitting means 25L or the second fragrance emitting means 25R at each point as necessary with movement. You can recognize the direction you should go. In addition, the user does not have to visually confirm the guidance display as in a general navigation device, so there is no need to move the line of sight each time such guidance display is updated. Since it is not necessary to confirm by hearing, it does not bother others around. The information presentation apparatus 100 can be used even by a visually impaired person or a hearing impaired person.

  The information presentation apparatus 100 in the above embodiment includes a first air ejection unit 25L that ejects air from the first direction toward the user (left fragrance ejection unit), and a first air that ejects air from the second direction toward the user. 2 air injection means 25R (right aroma injection section), current position detection means 10 for detecting the current position (GPS receiver), destination setting means 17 for setting a desired destination (operation switch section), The user has a control unit 19 that controls the ejection of air by at least one of the first air ejection unit 25L and the second air ejection unit 25R in accordance with the direction to be guided to the destination.

  If it does in this way, since a user will inject air from the 1st fragrance injection means 25L or the 2nd fragrance injection means 25R in each point as needed with movement, it specifies the injection direction of air, and oneself You can recognize the direction to go. In addition, the user does not have to visually confirm the guidance display as in a general navigation device, so there is no need to move the line of sight each time such guidance display is updated. Since it is not necessary to confirm by hearing, it does not bother others around. The information presentation apparatus 100 can be used even by a visually impaired person or a hearing impaired person.

  In the information presentation apparatus 100 according to the above embodiment, the control unit 19 determines whether the user should be guided when the current position detected by the current position detection unit 10 has not changed over a preset time. The fragrance injection is controlled by at least one of the first fragrance injection means 25L and the second fragrance injection means 25R.

  As described above, when the current position of the user does not change, there is a possibility that the user who has the information presentation device 100 is lost. In such a case, the information presentation device 100 determines the direction in which the user should proceed. A user can be guided by injecting a fragrance from at least one of the first fragrance injection means 25L and the second fragrance injection means 25R.

  In step S10, it is not determined that “the user is lost” just because the current position does not change, but further includes information on a place such as a specific place such as a sidewalk or an intersection. You may judge it. In other words, if only the information that the current position does not change, the user may enter the store and enjoy shopping, or may be doing window shopping even on the sidewalk. In such a case, it is possible to determine whether or not fragrance guidance is necessary by combining the information that “the current position is not changed” and the information that “there is a place in the store”. If you are in a store, there is a high possibility that you are shopping, so you can set up a program so that you do not give fragrance guidance.

  If there is no change in the current location not only in the store but also in the place where there is a “neighboring housing map” or “information guide board” nearby, you can look at the map or read the information on the bulletin board. In such a case, the program may be constructed so that the fragrance does not need to be guided.

  That is, in the information presentation apparatus 100 in the above embodiment, the control unit 19 determines that the current position detected by the current position detection unit 10 (GPS receiver) has not changed over a preset time period, and When it is detected that the place is a set place, the fragrance ejection by at least one of the first fragrance ejection means 25L and the second fragrance ejection means 25R is controlled according to the direction in which the user should be guided.

  In addition to the above-described configuration, the information presentation apparatus 100 in the above embodiment further has a specific place where the user should be guided at an intersection.

  In addition to the configuration described above, the information presentation apparatus 100 in the above embodiment further supports the first fragrance emitting means 25L and the second fragrance emitting means 25R toward the user, and the current position detecting means. 10. It has a garment-like casing in which the destination setting means 17 and the control means 19 are built.

  If it does in this way, the user can wear the information presentation apparatus 100 like clothes, and can make it wear naturally without making the user feel the information presentation apparatus 100 bothersome.

  In the information presentation apparatus 100 in the above embodiment, the first fragrance emitting means 25L is provided on the left side of the user, and the second fragrance emitting means 25R is provided on the right side of the user.

  Further, in this embodiment, the nozzle and the fragrance emitting portions 25L and 25R are configured so that the fragrance is emitted from the left and right toward the user's nose, but the fragrance is not limited to the left and right but from two different directions such as front and rear. What is necessary is just to make it fire toward a user.

  The direction of the nozzle is not directed to the nose, but the fragrance may be emitted about 20 cm in front of the nose, and the fragrance is respectively emitted from the left and right fragrance emitting portions 25L and 25R arranged around the left and right ears May be injected.

Second Embodiment
The information presentation apparatus 100a according to the second embodiment has substantially the same configuration as that of the first embodiment and performs substantially the same operation. Therefore, in the second embodiment, the same configurations and operations are denoted by the same reference numerals as those in FIGS. 1 to 6 in the first embodiment, and the description thereof is omitted. In the following description, different points are mainly described. .

  In the second embodiment, the information presentation apparatus 100a includes a gyro sensor 18 in addition to the configuration of the information presentation apparatus 100 in the first embodiment. The gyro sensor 18 detects the orientation of the user by detecting, for example, the rotational motion and the swinging state of the information presentation device 100. The information presentation device 100a includes a face direction determination device (not shown). This face direction discriminating device has a function of discriminating the orientation of the user's face.

FIG. 7 is a flowchart showing a procedure example of navigation processing using the information presentation apparatus 100a as the second embodiment.
In the second embodiment, the arithmetic control unit 19 executes a guide injection process different from that in the first embodiment. Since other processes are the same as those in the first embodiment, description thereof is omitted.

  In the following description, the term “anomalous intersection” is used. However, this “anomalous intersection” means that it is difficult to unambiguously identify the direction in which the user should proceed simply by guiding a right or left turn, such as a five-way road. Represents an irregular intersection. Further, as this irregular intersection, for example, an intersection where the direction in which the user should proceed is not unambiguous, such as a right-turn road and an obtuse right-turn road even when making a right turn. In the following description, other intersections are expressed as “normal intersections”.

<Induction Injection Processing in Second Embodiment>
First, in step S31, the arithmetic control unit 19 determines whether or not the current position is in the vicinity of the irregular intersection based on the map data relating to the vicinity of the current position measured by the GPS receiver 10. If the current position is not near the irregular intersection, the arithmetic control unit 19 executes step S34 described later, and if the current position is near the irregular intersection, executes step S32. Here, the user makes a left turn or a right turn by turning and moving at a normal intersection or a modified intersection based on the guidance information presented by the information presentation apparatus 100.

  In step S32, the arithmetic and control unit 19 emits a fragrance (for example, the above-described guiding fragrance) from, for example, the right fragrance emitting unit 25R until the user turns in the correct direction based on the guidance information.

  In step S <b> 33, the calculation control unit 19 causes the gyro sensor 18 to acquire the orientation of the user, and determines whether the user has turned in the correct direction based on the guidance information. The arithmetic control unit 19 executes step S32 again when the user is not turning in the correct direction, and executes step S6 described above when the user is turned in the correct direction.

  In step S34 described above, the arithmetic control unit 19 determines whether or not to go straight based on the guidance information in view of the current position of the user. If the arithmetic control unit 19 should go straight, for example, the left aroma injecting unit 25L and the right aroma injecting unit 25R simultaneously inject fragrance (step S35). On the other hand, the arithmetic control part 19 performs step S36, when it should not go straight on.

  In step S36, the arithmetic control unit 19 determines whether or not the user should turn left based on the guidance information. In the case where the arithmetic control unit 19 should make a left turn, for example, only the left-side fragrance emitting unit 25L emits fragrance (step S37). On the other hand, the arithmetic control part 19 performs step S38, when it should not turn left.

  In step S38, the arithmetic control unit 19 determines whether or not the user should make a right turn based on the guidance information. If the calculation control unit 19 should make a right turn, for example, only the right fragrance emitting unit 25R emits fragrance (step S39). On the other hand, the calculation control part 19 performs step S6 mentioned above, when it should not turn right.

  In addition to the above-described configuration, the information presentation apparatus 100a in the above embodiment further includes a face direction determination unit (a face direction determination device not shown) that determines the orientation of the user's face, and the control unit 19 includes: Fragrance is emitted from at least one of the first fragrance emitting means 25L and the second fragrance emitting means 25R until the direction toward the destination coincides with the direction in which the face is directed.

  In this way, even when the user is guided at an irregular intersection where it is difficult to grasp the turning amount, the user can accurately recognize the turning amount by continuously injecting the fragrance to the user. Can lead.

  In this embodiment, a case where the user is lost in the scene of an irregular intersection has been described. Needless to say, this embodiment may be applied to a normal intersection (crossroad or T-junction).

<Third Embodiment>
The information presentation apparatus 100 according to the third embodiment has substantially the same configuration as that of the first embodiment and performs substantially the same operation. For this reason, in the third embodiment, the same configurations and operations are denoted by the same reference numerals as in FIGS. 1 to 6 in the first embodiment, and the description thereof is omitted. In the following description, differences will be mainly described. .

  The third embodiment is different in that the arithmetic control unit 19 emits fragrance from at least one of the left fragrance emitting unit 25L and the right fragrance emitting unit 25R according to the fragrance control information table of the storage unit 13. In this fragrance control information table, the fragrance injection pattern and the fragrance component type are managed.

  The arithmetic control unit 19 changes at least one of the type of the fragrance component and the injection pattern to be emitted from at least one of the left fragrance emitting unit 25L and the right fragrance emitting unit 25R according to the guidance type of the searched route. . Here, the guidance type represents each instruction based on guidance information such as forward, left turn, right turn, turn right and arrival. In the following description, the types and injection patterns of these fragrance components are referred to as fragrance control information.

FIG. 8 is a flowchart illustrating a procedure example of navigation processing using the information presentation apparatus 100 as the third embodiment.
In the third embodiment, the calculation control unit 19 executes a guide injection process different from that in the first embodiment. Other processes are the same as those in the first embodiment unless there is a particular difference, and the description thereof will be omitted.

<Induction Injection Processing in Third Embodiment>
First, in step S41, the arithmetic control unit 19 refers to the fragrance control information table 13a in the storage unit 13 and grasps the fragrance control information to be used. Next, in step S42, the arithmetic control unit 19 injects a fragrance along with the fragrance control information. Here, the fragrance control information is roughly divided into two types of information, one information is a fragrance injection pattern, and the other information is a fragrance component type.

  In the third embodiment, instead of step S7 in the first embodiment, the calculation control unit 19 uses the left fragrance ejection unit 25L and the left fragrance emission unit 25L according to the fragrance control information indicating that the user has arrived at the destination, for example. A fragrance may be ejected from at least one of the right fragrance ejection part 25R (step S7a).

9-14 is a figure which shows the structural example of the fragrance control information table 13a, respectively.
In the fragrance control information table 13a shown in FIG. 9, the injection pattern is determined according to the instruction based on the guidance information. Here, “instruction” is similar to the above-described guidance type, and represents, for example, forward, left turn, right turn, turning right and arrival, and these instructions are indicated as shown in FIG. A code is associated.

<Aromatic injection pattern>
Specifically, when the instruction shown in FIG. 9 is “forward”, the injection pattern is “short” and “short”, for example, and when the instruction is “left turn”, the injection pattern is “short”, for example. , “Long”. When the instruction is “right turn”, the injection pattern is “long” or “short”, for example. When the instruction is “turn right”, the injection pattern is “long” or “long”, for example. Yes. When the instruction is “arrival”, the injection pattern is, for example, “short”, “short”, “long”. The “short” of these injection patterns is, for example, one unit (for example, 0.5 seconds) of the fragrance injection time, and the “long” of the injection pattern is, for example, an integral multiple of the “short” fragrance injection time. Is, for example, three times the “short” fragrance injection time.

  The arithmetic control unit 19 specifies these injection patterns using the injection code. Specifically, the arithmetic control unit 19 uses the expression “1” or “3” as shown in FIG. 10 in the fragrance control information table of the storage unit 13 according to the fragrance emission time of the injection pattern, for example. specify.

<Aromatic types>
On the other hand, the arithmetic control unit 19 can use the following types of fragrances prepared in the fragrance control information table of the storage unit 13.

  Specifically, when the instruction shown in FIG. 11 is “forward”, the type of fragrance is, for example, “Kinmokusei”, and when the instruction is “turn left”, the type of fragrance is, for example, “citrus”. ing. When the instruction is “right turn”, the type of fragrance is “lavender”, for example, and when the instruction is “turn right”, the type of fragrance is “rose”, for example. When the instruction is “arrival”, the type of fragrance is “short” or “coffee”, for example.

  The arithmetic control unit 19 identifies these fragrance types using the injection code. Specifically, the arithmetic control unit 19 uses expressions such as “01” to “05” in the fragrance control information table of the storage unit 13 according to the fragrance emission time of the injection pattern, for example, as shown in FIG. specify.

<Aroma injection pattern and concentration>
On the other hand, the arithmetic control unit 19 can use the following types of injection patterns and densities prepared in the aroma control information table of the storage unit 13.

  Specifically, when the instruction shown in FIG. 13 is “forward”, the injection pattern is, for example, small “short” and large “short”, and when the instruction is “left turn”, the injection pattern is, for example, large. “Short”, small “Long”. When the instruction is “right turn”, the injection pattern is, for example, a small “short” and a large “long”, and when the instruction is “turn right”, the injection pattern is, for example, a large “long” or a large “long”. " When the instruction is “arrival”, the injection pattern is, for example, a small “short”, a small “short”, and a large “long”. The “short” of these injection patterns is, for example, one unit (for example, 0.5 seconds) of the fragrance injection time, and the “long” of the injection pattern is, for example, an integral multiple of the “short” fragrance injection time. Is, for example, three times the “short” fragrance injection time.

  The arithmetic control unit 19 specifies these injection patterns using the injection code. Specifically, the arithmetic control unit 19 sets “00”, “01”, “10” in the fragrance control information table of the storage unit 13 as shown in FIG. "Or" 11 ".

  Specifically, this fragrance control information table is a table in which an instruction code is associated with a special code indicating a 2-bit injection pattern. In this fragrance control information table, for example, “00” indicates that the fragrance concentration is low (that is, the fragrance is thin) and the fragrance emission time is short. For example, “01” represents that the fragrance concentration is high (that is, the fragrance is deep) and the fragrance injection time is short. For example, “10” represents that the fragrance concentration is low and the fragrance injection time is long. For example, “11” represents that the fragrance concentration is high and the fragrance injection time is long. That is, these special codes indicate whether the first bit is low or high, and the last bit indicates whether the fragrance emission time is short or long.

  In addition to the configuration of the first embodiment described above, the information presentation apparatus 100 in the embodiment further includes the control unit 19 in accordance with the searched route guidance type, the first aroma injection unit 25L and the The kind of the fragrance component to be ejected from at least one of the second aroma ejection means 25R and at least one of the ejection pattern are changed.

If it does in this way, since the variation of the fragrance inject | emitted according to a guidance path | route increases, it can guide more finely with respect to a user.
In addition, when the user does not like the fragrance and performs guidance only by the flow of air, the “no fragrance output” mode is selected via the operation switch unit 17. If the control unit 19 determines that the “no fragrance output” mode is selected, the control unit 19 ignores the fragrance code in FIG. 12 and only injects air that does not contain fragrance, regardless of the instruction. To control. In this case, as shown in FIG. 9 and FIG. 13, guidance is performed based on the length of the injection time of the injected air, the strength of the injection speed, and the magnitude of the injection amount.
