Description

[Technical field]

[0001] The present invention relates to a guidance system, a guidance method, and a guidance program, and is a system that promotes independent movement, particularly by using hearing or touch, for people who have difficulty with spatial cognition (such as those with visual-spatial cognition disorders), by enabling them to concentrate on the scenery, be considerate of their surroundings, move around without getting lost, and arrive at their destination. [Background technology]

[0002] There are many navigation systems and map applications that guide pedestrians to their destinations. In particular, there is a navigation system for visually impaired people, as shown in Non-Patent Document 1. The navigation system shown in Non-Patent Document 1 uses image analysis using AI (artificial intelligence) instead of vision to realize automatic driving in place of human eyes.

[0003] However, although visual impairments have problems with visual information such as being unable to see, they tend to have high spatial awareness. Therefore, it is not considered important for visually impaired people to get lost, and measures are often required to prevent accidents caused by their inability to see.

[0004] On the other hand, people who have difficulty with spatial cognition (such as visual spatial cognitive impairment) have difficulty recognizing maps, perceiving space, and processing the spatial relationships in their brains. Furthermore, they are also not good at matching the direction of the map with the direction of their body, so they have difficulty remembering the scenery and are prone to getting lost. Some people also have difficulty with simultaneous tasks, and such people tend to have difficulty operating a smartphone or other device while considering their surroundings, and to simultaneously judge left and right using only their hearing. In the past, the only solution for such people to reach a destination that they have never been to before, or a destination that they have not remembered, was direct support for movement by a person. However, while direct support by a person is easy to understand, it tends to hinder the person's psychology of independence. Furthermore, there are problems that cannot be solved due to psychological compatibility between people, labor, and cost concerns. In order to enable the person to move at their own discretion without human support, a means to promote the person's independence is necessary. To solve this problem, a system is needed that promotes independent movement by allowing the person to concentrate on the scenery of their own volition and arrive at the destination while considering their surroundings. By using this system, people who have difficulty with spatial cognition (such as those with visual-spatial cognitive impairment) can reach a destination they have never been to before, or a destination they have not yet remembered, without getting lost and with less anxiety. Although symptoms of visual-spatial cognitive impairment are relatively common among people with developmental disorders, similar symptoms can also be seen in people with milder symptoms, such as those with higher brain dysfunction and mild cognitive impairment, and this solution is effective for people who have a strong desire to go out.

[0005] Also, Non-Patent Document 2 discloses a navigation device that is attached to shoes. However, this navigation device is for visually impaired people, and does not directly solve the problem of people who have difficulty in spatial cognition (such as those with visual-spatial cognitive impairment). This is because people who have difficulty in spatial cognition (such as those with visual-spatial cognitive impairment) need solutions to problems that make them easily get lost, but there is no need for a navigation function that requires them to focus their nerves on their feet, and the purpose is different.

[0006] Patent Document 1 also discloses a smart necklace, which includes a body defining at least one cavity, the body having a neck portion and first and second side portions, a pair of stereoscopic cameras configured to detect image data including depth information corresponding to an ambient environment of the smart necklace, a positioning sensor configured to detect position data corresponding to a position of the smart necklace, a persistent memory located in the at least one cavity, the persistent memory configured to store map data and object data, and a processor located in the at least one cavity, coupled to the pair of stereoscopic cameras, the positioning sensor, and the persistent memory, and configured to determine output data based on the image data, the position data, the map data, and the object data.

[0007] However, the smart necklace disclosed in Patent Document 1 does not have a functional unit that has the function of calculating the angle at which the guidance point is shifted relative to the front in which the user is facing. [Prior art documents] [Patent documents]

[0010] Therefore, the present invention has been made in consideration of the above problems, and aims to provide a system, guidance method, and guidance program that independently guides people who have difficulty with spatial cognition (such as those with visual-spatial cognition disorder) to their destination without getting lost, by allowing them to focus more on the scenery through their hearing or touch, without having to focus excessively on the map on their smartphone, and while being considerate of their surroundings. [Means for solving the problem]

[0011] In order to solve the above problems, one embodiment of the present invention provides a guidance system having first to third navigation units worn by a user, which allows the user to know the direction to be guided by hearing or touch, and is characterized in having a receiving unit that receives information regarding the guidance point to which the user should be guided and information regarding the content to be played, a memory unit that stores information regarding the guidance point and information regarding the content to be played, a control unit that calculates the angle at which the guidance point is offset from the front facing the user based on the information regarding the guidance point and selects the content to be played based on the calculation result, and an output unit that uses the first to third navigation units to output a guidance expression indicating the direction the user should proceed using a character expression based on the calculated angle.

[0013] The first navigation unit, the second navigation unit, and the third navigation unit may indicate the direction in which the user should go by sound based on the control of the main body unit.

[0014] The first navigation unit, the second navigation unit, and the third navigation unit may indicate a direction in which the user should go by using clavicle bone conduction sound based on the control of the main body unit.

[0015] The first navigation unit, the second navigation unit, and the third navigation unit may indicate the direction in which the user should proceed by haptic vibration based on the control of the main body unit.

[0018] The predetermined characters may include real or fictional characters.

[0019] The first navigation unit, the second navigation unit, or the third navigation unit may guide the user so that the user knows the guidance direction using a sensor attached to the guidance device unit based on input of the direction of the line segment guided by the first route transmitted from the mobile terminal and the distance between the point of the user's location information acquired by GPS and the nearest point of the line segment formed by the second route.

[0020] When the distance between the point in the user's location information acquired by GPS and transmitted from the mobile device and the nearest point of the line segment formed by the first route is greater than an arbitrary radius, the first navigation unit, the second navigation unit, or the third navigation unit may guide the user so that the user knows the guidance direction using a sensor attached to the guidance device unit based on input of the distance between the point in the user's location information acquired by GPS and transmitted from the mobile device and the nearest point of the line segment formed by the first route and the angle of the nearest point of the first route as seen from the point.

[0021] The first navigation unit, the second navigation unit, or the third navigation unit may guide the user so that the user knows the direction to be guided based on input of the direction of a line segment guided by the first route transmitted from the mobile terminal and a point of the user's location information acquired by GPS.

[0022] The first navigation unit, the second navigation unit, or the third navigation unit may guide the user so that the user knows the direction to be guided using a sensor attached to the guidance device unit based on input of the distance between a point in the user's location information acquired by GPS and transmitted from the mobile terminal and the final destination, and the angle of the final destination as viewed from the point.

[0023] In order to solve the above problems, one embodiment of the present invention provides a guidance method having first to third navigation units worn by a user, which allows the user to know the direction in which to guide the user by hearing or touch, and is characterized by having a receiving step of receiving information regarding a guidance point to which the user should be guided and information regarding the content to be played, a storage step of storing information regarding the guidance point and information regarding the content to be played, a control step of calculating an angle at which the guidance point is offset from the front facing the user based on the information regarding the guidance point, and selecting content to be played based on the calculation result, and an output step of outputting a guidance expression indicating the direction in which the user should proceed using a character expression using the first to third navigation units based on the calculated angle.

[0024] In order to solve the above problems, one embodiment of the present invention provides a guidance program having first to third navigation units worn by a user, which allows the user to know the direction in which to guide the user through hearing or touch, and is characterized in that the program has the following realizations in a computer: a receiving function for receiving information regarding the guidance point to which the user should be guided and information regarding the content to be played; a storage function for storing information regarding the guidance point and information regarding the content to be played; a control function for calculating the angle at which the guidance point is offset from the front in which the user is facing based on the information regarding the guidance point, and selecting the content to be played based on the calculation result; and an output function for outputting, using the first to third navigation units, a guidance expression indicating the direction in which the user should proceed based on the calculated angle, using a character representation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] [Guidance system] Hereinafter, a guidance system according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0028] FIG. 1 is a diagram showing a flow of transmitting information from a mobile terminal 10 to a guidance device unit 20 in a guidance system 1. The guidance system 1 is a system that includes a mobile terminal 10 and a guidance device unit 20, and guides a user (wearer) to reach a destination without getting lost through the guidance device unit 20. The guidance system 1 is a system in which the guidance device unit 20 conveys information about guidance points to the user through hearing or touch. Furthermore, the guidance system 1 may be configured such that the guidance device unit 20 calculates the angle at which the guidance points are offset from the front facing the user in response to an input from the mobile terminal 10. The mobile terminal 10 is configured of a general-purpose information processing terminal such as a smartphone, a tablet terminal, or a PC (personal computer), and accesses the guidance system 1 through a web browser or a dedicated application (not shown). By calculating the angle at which the guidance points are offset from the front facing the user in this way, the user can reach the destination without getting lost.

[0029] The guidance device unit 20 has a first navigation unit, a main body unit 21 that contacts the cervical vertebrae of the user's neck, an arm unit 22 that extends from the main body unit 21 to the left and right clavicles of the user, a second navigation unit 23 that is connected to the main body unit 21 by the arm unit 22 and contacts the left clavicle of the user, and a third navigation unit 24 that is connected to the main body unit 21 by the arm unit 22 and contacts the right clavicle of the user. The first navigation unit, the second navigation unit 23, the third navigation unit 24, and the main body unit 21 are speakers and bone conduction speakers. Vibration generating vibrators, motors, etc. are provided as actuators. When the main body unit 21 receives information about the guidance point from the mobile terminal 10, it calculates how much the guidance point is offset from the front facing the user, and outputs sound, clavicle bone conduction sound, and tactile vibration based on the calculation result from its own first navigation unit. Furthermore, the main body 21 transmits the calculation results to the second navigation unit 23 and the third navigation unit 24 via the arm unit 22, and the second navigation unit 23 and the third navigation unit 24 output sound, clavicle bone conduction sound, and tactile vibration. The sound may be a human voice and may have a frequency of about 200 Hz to 400 Hz or more, and may be reproduced as a file such as wav or mp3, for example. This will be described in detail in the explanation of FIG. 4. The navigation units may be four in total, two on the left and right at the rear and two on the left and right at the front, or one in the middle at the rear, two on the left and right at the front, and two on the left and right between the rear and front, for a total of five.

[0030] Fig. 2 shows a case where the mobile terminal 10 is fixed to the guidance device unit 20 in the guidance system 1. As shown in Fig. 2, the mobile terminal 10 is fixed to the main body unit 21 of the guidance device unit 20, and plays the role played by the guidance device unit 20 in Fig. 1. This will be described in detail in the explanation of Fig. 5. The guidance device unit 20 is appropriately provided with a fixing device (not shown) for fixing the mobile terminal 10.

[0031] Fig. 3 is a diagram showing a state in which the guidance device unit 20 in the guidance system 1 is attached above the neck and clavicle of the user. The guidance device unit 20 is a wide-area vibration actuator that can present tactile vibration, clavicle bone conduction sound, and sound by itself. As shown in Fig. 3, at least three wide-area vibration actuators are arranged to contact the torso or neck so as to surround the user's head or neck. The contact between the guidance device unit 20 and the neck and clavicle side of the user is obviously indirect contact through the skin or clothing.

[0032] Next, each functional unit of the main body 21 of the guidance device 20 in an embodiment in which the portable terminal 10 and the guidance device 20 in the guidance system 1 are separate will be described with reference to Fig. 4. The main body 21 has a receiving unit 30, a storage unit 40, a control unit 50, and an output unit 60.

[0033] The receiving unit 30 receives information on the guidance points and information on the content to be played from the mobile terminal 10 by wire or wirelessly. Information on the guidance points includes, for example, the direction to the guidance points, the distance, the angle of the corner, the number of guidance points to the goal, the number of guidance points being guided, and the like. The receiving unit 30 receives these as input values. The guidance points set by the mobile terminal 10 are set according to the situation, such as the next corner or the final destination. The guidance points may be set for each corner, a gentle and large curve, or only for the final destination. The content is not visual information but audio information, and may be audio or bone conduction sound. As will be described later, the direction to go is indicated by a voice like the voice of a mother or a robot.

[0034] The storage unit 40 stores information about the guidance points and information about the content to be played. Information about the guidance points includes, for example, the direction to the guidance points, the distance, the angle of the corner, the number of guidance points to the goal, the number of guidance points being guided, etc. The content is not visual information but audio information, and may be audio or bone-conducted sound. As will be described later, the direction to go is indicated by a voice like the voice of a mother or a robot.

[0035] The control unit 50 has an I / O 51, a ROM 52, a RAM 53, and a CPU 54. The control unit 50 calculates the angle at which the guidance point is shifted from the front facing the user based on the information received by the receiving unit 30. The value of the direction to be guided transmitted from the mobile terminal 10 is set to 0° to 359° clockwise with 0° being north. The direction in which the user is facing can be known by the guidance device unit 20 alone by a 9-axis sensor or the like attached to the main body 21 of the guidance device unit 20, so that the control unit 50 calculates the angle at which the guidance point is shifted from the front facing the user based on the input value from the mobile terminal 10. Information such as the distance to the point to be guided and the point number is also used as an input value for determining the output.

[0036] The output unit 60 plays files stored in the storage unit 40 based on the results of calculations performed by the control unit 50. Alternatively, the output unit 60 communicates with the mobile terminal 10 or the cloud, and plays files stored in the mobile terminal 10 or the cloud based on the results of calculations performed by the control unit 50 in the first navigation unit, the second navigation unit 23, and the third navigation unit 24. These playbacks are performed continuously at a frequency that provides an interactive experience. For example, 10 ms, 100 ms, 1 s, etc. are realistic.

[0037] The file derived by the calculation in the control unit 50 is played at the position of the navigation unit derived by the calculation. Sound, clavicle bone conduction sound, and tactile vibration can be played simultaneously or separately from one file. For example, the main elements of a human voice are composed of approximately 200Hz to 400Hz or more, and when this is played on the navigation unit as a wav or mp3 file, a stimulus is presented as a sound that travels through the air and reaches the ears. Therefore, by creating a wav file or mp3 file of a person's voice calling out or a sound effect using a sound with a frequency of approximately 200Hz to 400Hz or more and playing it on the device, it can be selectively used as a stimulus to the ears.

[0038] By adjusting the position and volume of the navigation unit that plays the sound, the direction from which the sound is perceived can be explicitly output. For example, if the third navigation unit 24 and the first navigation unit play sounds at the same volume, the sound will clearly feel as if it is coming from the right rather than the left. This property can be used to devise the content to be played and utilized for guidance and signals. This applies not only to the right, but also to front, back, left, right, and diagonal directions. Furthermore, when the same sound is output from each navigation unit, if the timing of playback from each navigation unit is shifted by several ms to several tens of ms, a sound with a unique surround feeling can be obtained around the head, so this property can be used in distinctive scenes such as the finish line and the start.

[0039] The guiding expression may include moving forward, turning, and stopping. The user may be guided in the direction to move forward by a character expression of a predetermined character. The predetermined character may include an actual character or a fictional character. The character referred to here refers to an expression mode characterized by a predetermined uniformity for the voice and vibration included in the guiding expression. When representing an arbitrary woman, the voice is female and the haptic vibration is presented with a gentle 1 second interval, and when representing an arbitrary man, the voice is male and the haptic vibration is presented with a strong 2 second interval.

[0040] Incidentally, when a problem occurs in guidance, if the guidance device unit 20 in the guidance system 1 presents a sense of direction, it will play back linguistic sounds (e.g., words) or non-linguistic sounds (e.g., animal cries or robot signal sounds) or sound effects. However, for users with the above-mentioned problems, whether the voice or sound is familiar is an important point. For example, they will not follow strangers. Therefore, in order for the guidance device unit 20 in the guidance system 1 and the intended use to be successfully established, it is important to consciously create a character that appears in the sound. For example, the voice of the user's mother, whose voice has been collected in advance from the right side, may be played back saying "It's this way." In addition to sound, it is also important to consciously create clavicle bone conduction sound (e.g., clavicle bone conduction sound created to simulate a robot) and tactile vibration (e.g., tactile vibration created to simulate a mother tapping the right shoulder).

[0041] As explained in the calculation method in the control unit 50, the files and data to be played are determined, and the files played by computer processing are generated by files and data stored in the device, computer processing, or computer processing linked to a cloud service so that the user can individually identify the character and recognize the character's emotions.

[0042] Specific details that can lead to the individual identification of the characters being played include sounds such as "a mother's gentle voice," "a mother's urging voice," "the voice of a familiar helper," "the voice of an official robot," "the bark of a favorite breed of dog," "a sound that can only produce musical notes but sounds like a nostalgic robot talking," "the voice of another version of yourself that exists in a digital world such as the metaverse," or sound effects.

[0043] For example, clavicle bone conduction sound, like sound, plays files and data that can be used to identify individual characters and recognize their emotions based on their "voice" or "tone." Haptic vibration also plays files and data that can be used to identify individual characters and recognize their emotions, such as "feeling like a mother gently tapping you on the shoulder," "feeling like a mother tapping you on the shoulder to urge you," "feeling like a robot clumsily tapping your shoulder," or "feeling like a robot clumsily massaging your shoulders."

[0044] The playback that leads to the individual identification and emotional recognition of characters as described above may be stored as a file or created by the user, or may be a sound waveform generated by computer processing using conventional methods, or an artificial voice generated by conventional machine learning, etc.

[0045] The playback by the character is output as described above, and the user is able to "identify the individual character" and "recognize the character's emotions." Normally, characters are presented with visual information, but the guidance device unit 20 does not present visual information, but instead encourages the individual identification and emotional recognition of the character through sound, clavicle bone conduction sound, and tactile vibration. This greatly reduces psychological anxiety for those who are the targets of the problem "mobility support" that the guidance system 1 is trying to solve, and is a major psychological factor in eliciting motivation to move and aiming for independence.

[0046] For example, automated voice guidance on telephones can encourage "individual character identification" and "recognition of character emotions," but this differs significantly from the above in terms of the calculation and device form that provides a sense of direction for the purpose of guidance assistance, as well as the presentation method and presentation device that allows the user to recognize direction, distance, timing, and the presence of landmarks.

[0047] Next, the functional units of the mobile terminal 10 when the mobile terminal 10 is fixed to the guidance device unit 20 will be described with reference to Fig. 5. The mobile terminal 10 has a receiving unit 130, a storage unit 140, a control unit 150, and an output unit 160.

[0048] The storage unit 140 stores information about the guidance points, such as the direction to the guidance point, the distance, the angle of the corner, the number of guidance points to the goal, the number of guidance points being guided, and the like.

[0049] The control unit 150 has an I / O 151, a ROM 152, a RAM 153, and a CPU 154. The control unit 150 calculates the angle by which the guidance point is shifted from the front facing the user based on the information received by the receiving unit 130. The value of the direction to be guided is set to 0° to 359° clockwise with 0° being north. Using a 9-axis sensor or the like attached to the mobile terminal 10, the control unit 150 calculates the angle by which the guidance point is shifted from the front facing the user. Information such as the distance to the point to be guided and the point number is also used as an input value for determining the output.

[0050] The output unit 160 plays files stored in the storage unit 140 based on the results of calculations performed by the control unit 150. Alternatively, the output unit 160 communicates with the cloud and plays files stored in the cloud based on the results of calculations performed by the control unit 150 in the first navigation unit, the second navigation unit 23, and the third navigation unit 24. These playback operations are performed continuously at a frequency that provides an interactive experience. For example, 10 ms, 100 ms, 1 s, etc. are realistic.

[0051] The file derived by the calculation in the control unit 150 is played at the position of the navigation unit derived by the calculation. Sound, clavicle bone conduction sound, and tactile vibration can be played simultaneously or separately from one file. For example, the main elements of a human voice are composed of approximately 200Hz to 400Hz or more, and when this is played on the navigation unit as a wav or mp3 file, a stimulus is presented as a sound that travels through the air and reaches the ears. Therefore, by creating a wav file or mp3 file of a person's voice calling out or a sound effect using a sound with a frequency of approximately 200Hz to 400Hz or more and playing it on the device, it can be selectively used as a stimulus to the ears.

[0052] By adjusting the position and volume of the navigation unit that plays the sound, the direction from which the sound is perceived can be explicitly output. For example, if the third navigation unit 24 and the first navigation unit play sounds at the same volume, the sound will clearly feel as if it is coming from the right rather than the left. This property can be used to devise the content to be played and utilized for guidance and signals. This applies not only to the right, but also to front, back, left, right, and diagonal directions. Furthermore, when the same sound is output from each navigation unit, if the timing of playback from each navigation unit is shifted by several ms to several tens of ms, a sound with a unique surround feeling can be obtained around the head, so this property can be used in distinctive scenes such as the finish line and the start, for example.

[0053] Next, the background of the navigation method required by the guidance system 1 will be explained. When moving while checking a map with one's eyes, a person looks at the map with his / her eyes and compares the information with the place where one is currently and the surrounding situation to grasp the relationship between the world and one's position. In contrast, people who are not good at grasping the relationship between the map information seen with their eyes and their own position are not sure of the relationship between the outside and their own position. When they look at the map in front of them, they walk without looking ahead. Also, although the error of GPS is said to be 20m, it can sometimes be off by about 100m due to the influence of nearby buildings, etc. If they are not familiar with the place or if they have a disability in spatial cognition, it is not easy to know how accurate their position on the map shown by GPS is.

[0054] In addition, when guidance is given by hearing and touch without using visual information, the user does not know the relationship between the outside and his / her position unless the user is already familiar with the location. Therefore, the guidance system 1 presents information by hearing or touch on which direction to move or how much to rotate the body based on the location and direction the user is facing at that time. For example, "Go right," "Turn left," or tap the right shoulder. When the user moves or rotates the body based on the presented information, the presentation of information is interactively changed so that the user can reach the destination. In addition to presenting information related to the above actions, it is also possible to present information related to distance and position. For example, "The next corner is 200m away" or "The final destination is 1km to the right."

[0055] Problems can arise when presenting action information as described above to guide the user from the location information obtained by GPS to an arbitrary location. For example, the following three examples of problems can arise.

[0056] Figure 6 shows an example of why a user cannot reach a destination when using GPS location information as the base point. R1 represents the road the user is currently traveling on, and R2 represents the road the user is about to travel. P1 represents the user's actual current position and direction, and P2 represents the position shifted due to a GPS error. P is the guidance point. In this case, the user's position is behind B (south S) of the guidance point, but the GPS position has shifted due to an error and is now forward F (north N), so the user is guided in the opposite direction, saying "Please go backward B (south S)," even though they should go forward F (north N).

[0057] Figure 7 shows another example of why a destination cannot be reached when the user's location information from GPS is used as the base point. R1 represents the road the user is currently traveling, R2 represents the road that has shifted due to GPS error, and R3 represents the road the user is about to travel. P1 represents the user's actual current position and direction, and P2 represents the position that has shifted due to GPS error. P is the guidance point. In this case, the user's position is to the left L (west W) of the guidance point, but the GPS position has shifted due to an error and is now to the right R (east E), so the user is told to "go forward F (north N)" and is guided to the front F (north N) where there is a wall, even though they should go to the right R (east E).

[0058] Figure 8 shows yet another example of why a destination cannot be reached when the user's location information from GPS is used as the base point. R2 represents the road the user is currently traveling on, R1 represents the road that has shifted due to GPS error, and R3 represents the road the user is about to travel. P2 represents the user's actual current position and direction, and P1 represents the position that has shifted due to GPS error. P is the guidance point. In this case, the user's position is below the guidance point B (south S), but the GPS position has shifted due to an error and is now left L (west W), so the user is told to "go right R (east E)" and is guided to right R (east E), which is off the route, even though they should turn left L (west W).

[0059] Therefore, rather than simply using a navigation system that guides the user from the point of the user's location information obtained by GPS to an arbitrary point, the system also uses information such as "the direction of the line segment of the route being guided," "the distance between the point of the user's location information obtained by GPS and the nearest point of the line segment of the next guided route," and "the angle of a corner."

[0060] FIG. 9 shows a specific example of a navigation algorithm by the guidance system 1, "Guidance to go straight along the route being guided (1)." R1 represents the road the user is currently traveling, P1 represents the actual position and direction of the user, and P2 represents the position shifted due to a GPS error. P is the guidance point. The "direction [θ] of the line segment guided by the route being guided L1" and the "distance [α] between point P2 of the user's position information acquired by GPS and the nearest point of the line segment formed by the next guide route L2" transmitted from the mobile terminal 10 are input. θ is set to 0° to 359° clockwise, with 0° being north.

[0061] The direction in which the guidance device unit 20 is facing can be known by the guidance device unit 20 alone, using a 9-axis sensor or the like attached to the guidance device unit 20. Regardless of GPS errors, the angle θ that is the front is known, and guidance is performed using this angle. For example, if θ is 30° and the orientation of the device (the orientation of the user's body) is 135° (southeast), it is known that the direction of θ will be the front when the body is rotated 105° to the left. The file to be output and the position of the main unit 21 are determined based on the rotation angle of the body to be guided and the distance α. Information is presented to the user, giving them a choice of what action to take after knowing the guidance direction that is the front. For example, it is possible to provide guidance in either "The direction of travel is to the right" or "The next guidance point is 100m to the right."

[0062] The output is as described in the description of the output unit 60.

[0063] FIG. 10 shows a specific example of the algorithm of the guidance method by the guidance system 1, "Guidance to go straight on the route being guided (2)". R1 represents the road the user is currently traveling on, R2 represents the road the user will travel next, and R3 represents the road the user will travel next. P1 represents the actual position and direction of the user, and P2 represents the position shifted due to a GPS error. P represents the guidance point. When the "distance [β] between point P2 of the user's position information acquired by GPS and the nearest point of the line segment formed by the route L1 being guided" transmitted from the mobile terminal 10 becomes larger than an arbitrary radius r, the "distance [β] between point P2 of the user's position information acquired by GPS and the nearest point of the line segment formed by the route L1 being guided" and the "angle [γ] of the nearest point of L1 as seen from P2" are input. γ is set to 0° to 359° clockwise, with 0° being north.

[0064] The direction in which the guidance device unit 20 is facing can be determined by the guidance device unit 20 alone using a 9-axis sensor or the like attached to the guidance device unit 20. Regardless of GPS error, guidance is provided so that the direction γ is always directed forward. For example, if γ is 120° and the direction of the guidance device unit 20 (the direction of the user's body) is directed 315° (northwest), it can be determined that the direction γ will be directed forward when the body is rotated 165° to the right R. The file to be output and the position of the main unit 21 are determined based on the rotation angle of the body to be guided and the distance β.

[0065] The output is as described in the description of the output unit 60.

[0066] Figure 11 shows a specific example of the algorithm of the navigation method of the guidance system 1, "guidance at a corner." "Guidance at a corner" occurs when α in "guidance to go straight on the route being guided (1)" becomes equal to or less than an arbitrary value. R1 represents the road the user is currently traveling on, R2 represents the road the user will travel next, and R3 represents the road the user will travel next. P1 represents the actual position and direction of the user, and P2 represents the position according to the GPS. k represents a corner. The "direction [θ] of the line segment guided by the route L1 being guided" sent from the mobile terminal 10 and the "distance [β] between point P2 in the user's position information acquired by GPS and the nearest point of the line segment formed by the route L1 being guided" are input.

[0067] The direction in which the guidance device unit 20 is facing can be known by the guidance device unit 20 alone, using a 9-axis sensor or the like attached to the guidance device unit 20. Regardless of GPS errors, it is possible to present a positional relationship in which the direction of θ is the front to the user. For example, if θ is 330° and the direction of the guidance device unit 20 (the direction of the user's body) is 45° (northeast), it is known that the direction of θ will be the front when the body is rotated 75° to the left L. (When the body is approximately facing the front, the corner mode ends.) The file to be output and the position of the main unit 21 are determined based on the rotation angle of the body to be guided and β. The "guidance at the corner" ends when the body is approximately facing the front or when β becomes equal to or greater than an arbitrary value. When β becomes equal to or greater than an arbitrary value, the guidance switches to straight-line guidance (2) on the route being guided, or a reroute is performed on the mobile terminal.

[0068] The output is as described in the description of the output unit 60.

[0069] FIG. 12 shows a specific example of the algorithm of the navigation method by the guidance system 1, "presenting only the final destination." P1 represents the actual position and direction of the user, and P2 represents the position shifted due to a GPS error. P is the guidance point. The "distance [b] between point P2 of the user's position information acquired by GPS and the final destination" and the "angle [a] of the final destination as seen from P2" transmitted from the mobile terminal 10 are input. a is set to 0° to 359° clockwise with 0° being north. The user can move freely to reach the final destination based on the position information of the final destination that is always notified to the user. For example, R1, R2, R3, R4, etc.

[0070] The direction in which the guidance device unit 20 is facing can be determined by the guidance device unit 20 alone, using a 9-axis sensor or the like attached to the guidance device unit 20. The guidance unit 20 provides guidance so that the guidance direction is known regardless of GPS errors. For example, if a is 330° and the direction of the guidance device unit 20 (the direction of the user's body) is facing 45° (northeast), it is known that if the body is rotated 75° to the left L, the direction of a will be directly ahead. The file to be output and the position of the main unit 21 are determined based on the rotation angle of the body to be guided and the distance b.

[0071] The output is as described in the description of the output unit 60.

[0072] [Guidance method and guidance program] Next, the guidance method and the guidance program in this embodiment will be described with reference to Fig. 13 and Fig. 14. The guidance method is executed by the CPU 54 of the control unit 50 based on the guidance program. The guidance program causes the control unit 50 to execute each of the functions of reception, control, output, and storage. These functions are executed in the order shown in the figure. Note that each function overlaps with the description of the guidance system 1 described above, so details will be omitted.

[0073] As can be seen from the flowchart of Fig. 13, the process of the control unit 50 includes a receiving step (S11), a control step (S12), and an output step (S13). Also, as can be seen from the flowchart of Fig. 14, the process includes a storing step (S21), a control step (S22), and an output step (S23). Of course, various steps necessary for the operation of the control unit 50 itself are naturally included.

[0074] The receiving function is that the main body 21 receives information about the guidance point input from the mobile terminal 10, such as the direction to the guidance point, the distance, the angle of the corner, the number of guidance points to the goal, the number of guidance points being guided, etc. (S10: Reception step).

[0075] The control function is such that the main body unit 21 calculates the angle at which the guidance point is shifted with respect to the front facing the user, based on the information received in the receiving step (S12: control step).

[0076] The output function is such that the main body unit 21 outputs, based on the calculation result in the control step, a guidance expression indicating the direction in which the user should proceed to the first navigation unit, the second navigation unit 23, and the third navigation unit 24 (S13: output step).

[0077] The storage function is that the mobile terminal 10 stores information about the guidance points, such as the direction to the guidance points, the distance, the angle of the corner, the number of guidance points to the goal, the number of guidance points being guided, and the like (S21: storage step).

[0078] The control function is to calculate an angle by which the mobile terminal 10 displaces the guiding point with respect to the front facing the user, based on the information on the guiding point stored in the storage step (S22: control step).

[0079] The output function is that the mobile terminal 10 outputs, based on the calculation result in the control step, a guiding expression indicating the direction in which the user should proceed to the first navigation unit, the second navigation unit 23, and the third navigation unit 24 (S23: output step).

[0080] The computer program of the present invention described above may be recorded on a processor-readable recording medium, and the recording medium may be a "non-transitory tangible medium" such as a tape, disk, card, semiconductor memory, programmable logic circuit, etc.

[0081] The computer program can be implemented using, for example, a scripting language such as ActionScript or JavaScript (registered trademark), an object-oriented programming language such as Objective-C or Java (registered trademark), or a markup language such as HTML5.

[0082] According to such an embodiment, a person who has difficulty with spatial cognition (such as a person with visual-spatial cognition disorder) can be guided to his / her destination without getting lost by hearing or touching rather than by relying on vision.

[0083] Finally, a "table" is added that lists the output expression modes, which collectively show the "sound," "vibration," and "bone conduction sound" output from the first navigation unit 23, the second navigation unit 24, and the third navigation unit 24 of the main body unit 21 when the user moves forward, turns right, turns left, and moves backward. The following table is merely one example of the output expression modes.
