DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] In order to describe the present disclosure in more detail, embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0010] Embodiment 1 FIG. 1 is a configuration diagram showing a facility guidance device 2 according to the first embodiment. FIG. 2 is a hardware configuration diagram showing hardware of facility guidance device 2 according to the first embodiment. In FIG. 1, a user terminal 1 is realized by, for example, a mobile terminal or a personal computer. The user terminal 1 transmits to the facility guidance device 2 personal information of the visually impaired person who is a facility user, the personal information including face image data showing a face image of the visually impaired person and type information showing the type of visual impairment. Visually impaired people include those who are completely blind and those who are not completely blind (hereinafter referred to as "non-blind visually impaired people"). Non-blind visually impaired people can see the guidance images of facilities depending on the display format of the images.

[0011] The facility guidance device 2 includes a registration reception unit 11, a personal information acquisition unit 12, a visually impaired person determination unit 13, a guidance image generation unit 14, an image display processing unit 15, and a voice output unit 16. The facility guide device 2 is connected to the user terminal 1 via, for example, the Internet. The facility guidance device 2 is a device that displays guidance images for visually impaired people or guidance images for non-visually impaired people as guidance images for a facility. The guidance images include not only still images but also moving images. Of course, the guidance images may be a combination of still images and moving images. As shown in FIG. 4, the signage 3 is an electronic signboard provided with a camera 41, a switch 42 for calling an attendant, a display 43, a speaker 44, and a microphone 45. The facility guidance device 2 is built into the signage 3. However, this is merely an example, and the facility guidance device 2 may be provided outside the signage 3.

[0012] The registration receiving unit 11 is realized by, for example, a registration receiving circuit 21 shown in FIG. The registration reception unit 11 receives personal information of the visually impaired person transmitted from the user terminal 1. The registration reception unit 11 receives registration of a facial image of a visually impaired person indicated by facial image data included in the personal information of the visually impaired person, and the type of visual impairment indicated by type information included in the personal information.

[0013] The personal information acquiring unit 12 is realized by, for example, a personal information acquiring circuit 22 shown in FIG. The personal information acquiring unit 12 acquires personal information of the facility user. Specifically, the personal information acquiring unit 12 acquires, via the camera 41 of the signage 3, a facial image of the facility user as the facility user's personal information. The personal information acquiring unit 12 outputs a facial image of the facility user to the visually impaired person determining unit 13 as the facility user's personal information.

[0014] The visually impaired person determination unit 13 is realized by, for example, a visually impaired person determination circuit 23 shown in FIG. The visually impaired person determination unit 13 acquires personal information of the facility user from the personal information acquisition unit 12. The visually impaired person determination unit 13 determines whether or not the facility user is visually impaired based on the personal information. Specifically, the visually impaired person determination unit 13 compares the facial image of the visually impaired person whose registration has been accepted by the registration acceptance unit 11 with the facial image of the facility user acquired by the personal information acquisition unit 12. If the facial image of the facility user is present among the facial images of the visually impaired person whose registration has been accepted by the registration acceptance unit 11, the visually impaired person determination unit 13 determines that the facility user is visually impaired. If the facial image of the facility user is not present among the facial images of the visually impaired person whose registration has been accepted by the registration acceptance unit 11, the visually impaired person determination unit 13 performs a secondary determination of whether or not the facility user has a visual impairment using an image of the facility user that also includes information other than the facial image of the facility user. The visually impaired person determination unit 13 acquires the image of the facility user that also includes information other than the facial image of the facility user via the camera 41 of the signage 3 as personal information of the facility user. In the secondary determination, the visually impaired person determination unit 13 determines whether the facility user has a visual impairment by searching for whether there is anything that indicates that the facility user is visually impaired, such as whether the facility user is wearing sunglasses, carrying something that looks like a white paper, or accompanying a guide dog, from the image of the facility user that includes information other than the facial image of the facility user. If the visually impaired person determination unit 13 determines in the secondary determination that the facility user has a visual impairment, the visually impaired person determination unit 13 determines that the facility user is visually impaired even if the facial image of the facility user does not exist among the facial images of the visually impaired people. If the visually impaired person determination unit 13 determines in the secondary determination that the facility user does not have a visual impairment, or if the secondary determination cannot be made, it determines that the facility user is not visually impaired. The visually impaired person determination unit 13 determines that the type of visual impairment of the facility user is one of the types for which registration has been accepted by the registration acceptance unit 11. The visually impaired person determination unit 13 outputs the determination result to each of the guidance image generation unit 14 and the voice output unit 16.

[0015] The guide image generating unit 14 is realized by, for example, a guide image generating circuit 24 shown in FIG. The guidance image generating unit 14 acquires the determination result from the visually impaired person determining unit 13 . If the visually impaired person determination unit 13 determines that the facility user is a visually impaired person who is not completely blind, the guidance image generation unit 14 generates a guidance image for visually impaired people as a guidance image for the facility. When the type of visual impairment is determined by the visually impaired person determination unit 13, the guidance image generation unit 14 generates a guidance image for the visually impaired person according to the type of visual impairment. If the visually impaired person determination unit 13 determines that the facility user is not visually impaired, the guidance image generation unit 14 generates a guidance image for non-visually impaired people as a guidance image for the facility. The guidance image generation unit 14 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the image display processing unit 15. However, this is merely an example, and if the visually impaired person determination unit 13 determines that the facility user is not visually impaired, the guidance image generation unit 14 does not need to generate a guidance image for non-visually impaired people and does not need to output anything to the image display processing unit 15. If the visually impaired person determination unit 13 determines that the facility user is not visually impaired and does not output anything to the image display processing unit 15, the display 43 of the signage 3 will continue to display the same thing as when the facility user stood in front of the signage 3. If the visually impaired person determination unit 13 determines that the type of visual impairment is total blindness, the guidance image generation unit 14 outputs audio guidance data to the audio output unit 16, which indicates by audio the contents of the display of the facility guidance image.

[0016] The image display processing unit 15 is realized by, for example, an image display processing circuit 25 shown in FIG. The image display processing unit 15 acquires a guidance image for visually impaired people or a guidance image for non-visually impaired people from the guidance image generating unit 14. The image display processing unit 15 causes the display 43 of the signage 3 to display the acquired guide image.

[0017] The audio output unit 16 is realized by, for example, an audio output circuit 26 shown in FIG. For example, when a visually impaired person operates switch 42 for calling an attendant, the audio output unit 16 outputs audio data indicating the voice of the facility attendant to the speaker 44, thereby outputting the voice of the facility attendant from the speaker 44. When voice guidance data is output from the guidance image generating unit 14, the voice output unit 16 outputs the voice guidance data to the speaker 44. The speaker 44 outputs a voice indicated by the guidance voice data.

[0018] In Fig. 2, it is assumed that each of the components of the facility guidance device 2, that is, the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guide image generation unit 14, the image display processing unit 15, and the voice output unit 16, is realized by dedicated hardware as shown in Fig. 3. In other words, it is assumed that the facility guidance device 2 is realized by a registration acceptance circuit 21, a personal information acquisition circuit 22, a visually impaired person determination circuit 23, a guide image generation circuit 24, an image display processing circuit 25, and a voice output circuit 26. Each of the registration reception circuit 21, personal information acquisition circuit 22, visually impaired person determination circuit 23, guidance image generation circuit 24, image display processing circuit 25 and voice output circuit 26 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination of these.

[0019] The components of the facility guidance device 2 are not limited to those realized by dedicated hardware, and the facility guidance device 2 may be realized by software, firmware, or a combination of software and firmware. The software or firmware is stored as a program in the memory of a computer. The computer means hardware that executes the program, and includes, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a central processing unit, a processing unit, an arithmetic unit, a microprocessor, a microcomputer, a processor, or a DSP (Digital Signal Processor).

[0020] FIG. 3 is a hardware configuration diagram of a computer in the case where facility guidance device 2 is realized by software, firmware, or the like. When the facility guidance device 2 is realized by software, firmware, or the like, a facility guidance program for causing a computer to execute each of the processing procedures in the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the image display processing unit 15, and the voice output unit 16 is stored in the memory 31. The respective processing procedures are a registration acceptance processing procedure in the registration acceptance unit 11, an information acquisition processing procedure in the personal information acquisition unit 12, a determination processing procedure in the visually impaired person determination unit 13, an image generation processing procedure in the guidance image generation unit 14, a display processing procedure in the image display processing unit 15, and a voice output processing procedure in the voice output unit 16. Then, the processor 32 of the computer executes the facility guide program stored in the memory 31 .

[0021] 2 shows an example in which each of the components of the facility guidance device 2 is realized by dedicated hardware, while Fig. 3 shows an example in which the facility guidance device 2 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the facility guidance device 2 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0022] FIG. 4 is an explanatory diagram showing the signage 3. As shown in FIG. In FIG. 4, a camera 41 captures an image of the face of a facility user as personal information of the facility user. Camera 41 outputs a facial image of the facility user to personal information acquisition unit 12 as the facility user's personal information. The attendant call switch 42 is a switch for calling an attendant at the facility where the signage 3 is installed. When the attendant call switch 42 is operated by, for example, a visually impaired person, an attendant at the facility is called. Examples of the facility include a station, a library, a city hall, a hospital, or a shopping mall.

[0023] The display 43 displays the guide image generated by the guide image generating unit 14. In addition, the display 43 displays the conversation between the visually impaired person and the attendant in text form. For example, when a visually impaired person operates switch 42 for calling an attendant, speaker 44 outputs the voice of a facility attendant. Further, the speaker 44 outputs a voice indicated by the voice guidance data output from the voice output unit 16 . The microphone 45 collects the voices and other sounds of the visually impaired person.

[0024] Next, the operation of facility guidance device 2 shown in FIG. 1 will be described. FIG. 5 is a flowchart showing a facility guidance method which is a processing procedure of the facility guidance device 2. In the facility guidance device 2 shown in FIG. 1, a visually impaired person is required to register personal information in the facility guidance device 2 in advance when using a facility. A visually impaired person operates the user terminal 1 to capture an image of his / her face. The visually impaired person also operates the user terminal 1 to input the type of visual impairment. The types of visual impairment include, for example, visual impairment, visual field impairment, color vision impairment, light vision impairment, or total blindness. A visual impairment is sometimes called low vision. If a person can read letters and other text when they are enlarged or can read letters and other text when they are used with a visual aid, then that person is considered to have a visual impairment. Visual field impairment is a disability that narrows the range of vision that can be seen without moving the eyes. There are two types of visual field impairment: centripetal visual field constriction, in which only the central part can be seen and the surroundings gradually become invisible, and central darkening, in which the central part cannot be seen while the surroundings can be seen vaguely. Color vision deficiency is a disability that makes it difficult to distinguish certain colors. Light sensitivity is a disorder in which the ability to sense light and distinguish its intensity is impaired. Symptoms of light sensitivity include feeling dazzled even in weak light, and feeling weak light even in strong light. The user terminal 1 transmits to the facility guidance device 2, as personal information of the visually impaired person, personal information including face image data showing a face image of the visually impaired person and type information showing the type of visual impairment.

[0025] The registration reception unit 11 of the facility guidance device 2 receives the personal information of the visually impaired person transmitted from the user terminal 1. The registration reception unit 11 receives registration of a facial image of a visually impaired person indicated by facial image data included in the personal information of the visually impaired person, and the type of visual impairment indicated by type information included in the personal information. FIG. 6 is an explanatory diagram showing a list of facial images and the like of visually impaired persons whose registration has been accepted by the registration acceptance unit 11. As shown in FIG. In the example of FIG. 6, facial images and the like of visually impaired persons (1) to (4) are registered. To simplify the drawings, the facial images of the visually impaired persons (1) to (4) are distinguished by the symbols circle, triangle, ◇, and square. The type of visual impairment of visually impaired person (1) is a visual impairment, the type of visual impairment of visually impaired person (2) is a visual field impairment, the type of visual impairment of visually impaired person (3) is a color blindness impairment, and the type of visual impairment of visually impaired person (4) is a light blindness impairment.

[0026] When a facility user stands in front of the signage 3, the camera 41 of the signage 3 captures an image of the facility user's face. The personal information acquisition unit 12 acquires a facial image of the facility user captured by the camera 41 as the facility user's personal information (step ST1 in FIG. 5). The personal information acquiring unit 12 outputs a facial image of the facility user to the visually impaired person determining unit 13 as the facility user's personal information. In the facility guidance device 2 shown in Fig. 1, when a facility user stands in front of the signage 3, the camera 41 of the signage 3 captures an image of the user's face. However, this is merely one example, and the camera 41 of the signage 3 may also capture an image of the user's face when the facility user operates, for example, the switch 42 for calling an attendant or operation switches 71a and 71b (see Fig. 12) described below.

[0027] The visually impaired person determination unit 13 acquires personal information of the facility user from the personal information acquisition unit 12. The visually impaired person determination unit 13 compares the facial image of the visually impaired person whose registration has been accepted by the registration acceptance unit 11 with the facial image of the facility user, which is the personal information of the facility user. The facial image comparison process itself is a known technique, and therefore a detailed description thereof will be omitted. If the facial image of a facility user is present among the facial images of visually impaired people whose registration has been accepted by the registration acceptance unit 11 (step ST2 in Figure 5: YES), the visually impaired person determination unit 13 determines that the facility user is visually impaired (step ST3 in Figure 5). In addition, the visually impaired person determination unit 13 determines that the type of visual impairment of the facility user is one that has been accepted for registration by the registration acceptance unit 11. For example, if the facility user is visually impaired (1), the visually impaired person determination unit 13 determines that the type of visual impairment is visual impairment, as shown in Figure 6. For example, if the facility user is visually impaired (2), the visually impaired person determination unit 13 determines that the type of visual impairment is visual field impairment, as shown in Figure 6. Note that if the type of visual impairment is total blindness, the visually impaired person determination unit 13 determines that the facility user is a non-totally blind visually impaired person.

[0028] If the facial image of the facility user is not present among the facial images of visually impaired people whose registration has been accepted by the registration acceptance unit 11 (step ST2 in Figure 5: NO), the visually impaired person determination unit 13 performs a secondary determination of whether or not the facility user has a visual impairment using an image of the facility user that also includes information other than the facial image of the facility user (step ST4a in Figure 5). The visually impaired person determination unit 13 acquires an image of the facility user including information other than the facial image of the facility user as personal information of the facility user via the camera 41 of the signage 3. In the secondary determination, the visually impaired person determination unit 13 determines whether the facility user has a visual impairment by searching for whether there is anything indicating that the facility user is visually impaired, such as whether the facility user is wearing sunglasses, carrying something that looks like a white paper, or accompanying a guide dog, from the image of the facility user including information other than the facial image of the facility user. If the visually impaired person determination unit 13 determines in the secondary determination that the facility user has a visual impairment, the visually impaired person determination unit 13 determines that the facility user is visually impaired even if the facial image of the facility user does not exist among the facial images of the visually impaired person. If the visually impaired person determination unit 13 determines in the secondary determination that the facility user does not have a visual impairment, or if the secondary determination cannot be made, it determines that the facility user is not visually impaired (step ST4b in FIG. 5). The visually impaired person determination unit 13 outputs the determination result to each of the guidance image generation unit 14 and the voice output unit 16.

[0029] The guidance image generating unit 14 acquires the determination result from the visually impaired person determining unit 13 . If the visually impaired person determination unit 13 determines that the facility user is a non-totally blind visually impaired person (step ST5 in Figure 5: YES), the guidance image generation unit 14 generates a guidance image for visually impaired people as a guidance image for the facility (step ST6 in Figure 5). When the type of visual impairment is determined by the visually impaired person determination unit 13, the guidance image generation unit 14 generates a guidance image for the visually impaired person according to the type of visual impairment.

[0030] If the type of visual impairment is a visual impairment, the guidance image generating unit 14 generates a guidance image with a larger font size than a guidance image for non-visually impaired people. Also, if the characters displayed in the guidance image for visually impaired people are, for example, kanji characters with many strokes, the guidance image generating unit 14 converts the kanji characters into either hiragana or katakana characters to make the guidance image easier to read.

[0031] If the type of visual impairment is visual field impairment, the visible range is narrow and it may be difficult to see the entire display 43 of the signage 3. For this reason, the guide image generating unit 14 generates a guide image having a display area within a range that can be confirmed by a visually impaired person with visual field impairment, as shown in Fig. 7A. Since the display area is narrower than the entire display 43, it is highly likely that it will be confirmed by a visually impaired person with visual field impairment. In addition, in order to enable visually impaired persons to easily find the display area, the guide image generation unit 14 generates a guide image on the display 43 that includes an arrow indicating the position of the displayed display area, as shown in FIG. 7A. When a visually impaired person is unable to find the display area, if they can see the arrows, they may be able to find the display area where the directions are displayed by following the arrows and shifting their line of sight. Since the display area is smaller than the entire display 43, it may not be possible to include all of the information. In such a case, the guide image generating unit 14 divides the information and generates a guide image that displays the display areas including each piece of divided information in order, as shown in Fig. 7B. In the example of Fig. 7B, the divided information (1), the divided information (2), and the divided information (3) are displayed in that order. FIG. 7A is an explanatory diagram showing a guide image for a visually impaired person with impaired visual field. FIG. 7B is an explanatory diagram showing a guide image in the case where the display content of the display area changes in time series.

[0032] If the type of visual impairment is color vision impairment, the guidance image generating unit 14 generates a guidance image using a color combination that can be recognized even by a person with color vision impairment. Since the color combination that can be recognized is itself publicly known, a detailed description thereof will be omitted. If the type of visual impairment is photosensitivity impairment and the symptom is photosensitivity impairment accompanied by glare, the guidance image generating unit 14 generates a guidance image with lower screen brightness than a guidance image for non-visually impaired people.

[0033] If the type of visual impairment is photosensitivity impairment, and the symptom is that even strong light is perceived as weak light, the guide image generating unit 14 generates a guide image with a higher screen brightness than a guide image for non-visually impaired people.

[0034] If the visually impaired person determination unit 13 determines that the facility user is non-visually impaired (step ST5 in Figure 5: NO), the guidance image generation unit 14 generates a guidance image for non-visually impaired people as a guidance image for the facility (step ST7 in Figure 5). Since non-visually impaired people are able-bodied people who have no visual impairment, the guidance image generating unit 14 generates a detailed guidance image that contains more information than a guidance image for visually impaired people, for example. The guidance image generating unit 14 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the image display processing unit 15. If the visually impaired person determination unit 13 determines that the type of visual impairment is total blindness, the guidance image generation unit 14 outputs audio guidance data to the audio output unit 16, which indicates by audio the contents of the display of the facility guidance image.

[0035] The image display processing unit 15 acquires a guidance image for visually impaired people or a guidance image for non-visually impaired people from the guidance image generating unit 14. The image display processing unit 15 causes the acquired guide image to be displayed on the display 43 of the signage 3 (step ST8 in FIG. 5). When the guidance image is displayed on the display 43 of the signage 3, the image display processing unit 15 notifies facility users that guidance is being given. Specifically, when the guidance image is displayed on the display 43 of the signage 3, the image display processing unit 15 notifies facility users that guidance is being given by highlighting "guidance in progress" on a part of the display 43. An example of the part of the display 43 is the upper right corner of the display 43, or the upper left corner of the display 43. Examples of highlighting "guidance in progress" include a display form in which the text is displayed larger than the text in the guidance image, or a display form in which the text "guidance in progress" flashes. Alternatively, when the image display processing unit 15 is displaying a guidance image on the display 43 of the signage 3, it lights up an indicator light (not shown) provided on the upper part, the lower part, or the side part of the display 43. If the words "Guidance in progress" are printed on the surface of the indicator light, the words "Guidance in progress" are highlighted by turning on the indicator light.

[0036] A visually impaired person can call a facility attendant by operating the attendant call switch 42. When the visually impaired person operates the switch 42 for calling an attendant, the audio output unit 16 outputs audio data indicating the voice of the facility attendant to the speaker 44, thereby causing the voice of the facility attendant to be output from the speaker 44. This allows the visually impaired person to talk to the attendant via the signage 3. By talking to the attendant, the visually impaired person can receive support, such as being shown around the facility, from the attendant. When voice guidance data is output from the guidance image generating unit 14, the voice output unit 16 causes the speaker 44 to output a voice indicated by the voice guidance data.

[0037] In the above-described first embodiment, the facility guidance device 2 is configured to include a personal information acquisition unit 12 that acquires personal information of the facility user, and a visually impaired person determination unit 13 that determines whether or not the facility user is a non-blind visually impaired person based on the personal information acquired by the personal information acquisition unit 12. The facility guidance device 2 also includes a guidance image generation unit 14 that generates a guidance image for visually impaired people as a guidance image for the facility if the visually impaired person determination unit 13 determines that the facility user is a non-blind visually impaired person. Therefore, if the facility user is a non-blind visually impaired person, the facility guidance device 2 can display a guidance image that is easy for non-blind visually impaired people to see.

[0038] Embodiment 2 In the second embodiment, a facility guidance device 2 including a personal information acquiring unit 17 that acquires, as personal information of a facility user, visually impaired information indicating that the facility user is visually impaired will be described.

[0039] Fig. 8 is a configuration diagram showing a facility guidance device 2 according to embodiment 2. In Fig. 8, the same reference numerals as in Fig. 1 indicate the same or corresponding parts, and detailed description thereof will be omitted. Fig. 9 is a hardware configuration diagram showing hardware of a facility guidance device 2 according to embodiment 2. In Fig. 9, the same reference numerals as in Fig. 2 indicate the same or corresponding parts, and detailed description thereof will be omitted. The facility guidance device 2 includes a personal information acquisition unit 17 , a visually impaired person determination unit 18 , a guidance image generation unit 14 , an image display processing unit 15 , and a voice output unit 16 .

[0040] The personal information acquiring unit 17 is realized by, for example, a personal information acquiring circuit 27 shown in FIG. The personal information acquiring unit 17 acquires personal information of the facility user. Specifically, the personal information acquisition unit 17 acquires, via the camera 41 of the signage 3, personal information of the facility user, including visually impaired information indicating that the facility user is visually impaired and type information indicating the type of visual impairment. The visually impaired person information and the type information are each included in, for example, one two-dimensional barcode. When the visually impaired person holds the two-dimensional barcode displayed on the display of his / her mobile terminal over the camera 41 having a barcode reader function, the visually impaired person information and the type information are each captured by the personal information acquisition unit 17. The personal information acquisition unit 17 outputs the visually impaired person information and the type information to the visually impaired person determination unit 18 as the personal information of the facility user.

[0041] The visually impaired person determination unit 18 is realized by, for example, a visually impaired person determination circuit 28 shown in FIG. The visually impaired person determination unit 18 acquires personal information of the facility user from the personal information acquisition unit 17. If visually impaired person information is acquired from the personal information acquisition unit 17, the visually impaired person determination unit 18 determines that the facility user is visually impaired. When type information is acquired from personal information acquisition unit 17, visually impaired person determination unit 18 determines that the type of visual impairment of the facility user is the type indicated by the type information. The visually impaired person determination unit 18 outputs the determination result to each of the guidance image generation unit 14 and the voice output unit 16.

[0042] In Fig. 8, it is assumed that each of the components of the facility guidance device 2, that is, the personal information acquisition unit 17, the visually impaired person determination unit 18, the guidance image generation unit 14, the image display processing unit 15, and the audio output unit 16, is realized by dedicated hardware as shown in Fig. 9. In other words, it is assumed that the facility guidance device 2 is realized by the personal information acquisition circuit 27, the visually impaired person determination circuit 28, the guidance image generation circuit 24, the image display processing circuit 25, and the audio output circuit 26. Each of the personal information acquisition circuit 27, the visually impaired person determination circuit 28, the guidance image generation circuit 24, the image display processing circuit 25 and the voice output circuit 26 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0043] The components of the facility guidance device 2 are not limited to those realized by dedicated hardware, and the facility guidance device 2 may be realized by software, firmware, or a combination of software and firmware. 3 is stored in memory 31 for causing a computer to execute the respective processing procedures in the personal information acquisition unit 17, the visually impaired person determination unit 18, the guidance image generation unit 14, the image display processing unit 15, and the audio output unit 16. The respective processing procedures are an information acquisition processing procedure in the personal information acquisition unit 17, a determination processing procedure in the visually impaired person determination unit 18, an image generation processing procedure in the guidance image generation unit 14, a display processing procedure in the image display processing unit 15, and an audio output processing procedure in the audio output unit 16. Then, the processor 32 shown in FIG.

[0044] 9 shows an example in which each of the components of the facility guidance device 2 is realized by dedicated hardware, while Fig. 3 shows an example in which the facility guidance device 2 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the facility guidance device 2 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0045] Next, the operation of the facility guidance device 2 shown in Fig. 8 will be described. However, since the facility guidance device 2 is the same as that shown in Fig. 1 except for the personal information acquisition unit 17 and the visually impaired person determination unit 18, the operation of the personal information acquisition unit 17 and the visually impaired person determination unit 18 will be mainly described here. Unlike the facility guidance device 2 shown in FIG. 1, the facility guidance device 2 shown in FIG. 8 does not require a visually impaired person to register personal information in advance in the facility guidance device 2 when using a facility.

[0046] The visually impaired person information and the type information are each included in, for example, one two-dimensional barcode. For example, if an app for including the visually impaired person information and the type information in one two-dimensional barcode is installed in a mobile terminal of a visually impaired person, the visually impaired person can start up the app to include the visually impaired person information and the type information in one two-dimensional barcode. When a visually impaired person holds a two-dimensional barcode displayed on the display of a mobile terminal, for example, over a camera 41 equipped with a barcode reader function, the visually impaired person information and type information are each captured by the personal information acquisition unit 17. The personal information acquisition unit 17 outputs the visually impaired person information and the type information to the visually impaired person determination unit 18 as the personal information of the facility user. In the facility guidance device 2 shown in Fig. 8, the visually impaired person information and the type information are each included in one two-dimensional barcode. However, this is merely one example, and the visually impaired person information and the type information may each be printed on, for example, a disability certificate. In this case, when a visually impaired person holds the disability certificate over camera 41, the visually impaired person information and the type information are each captured by personal information acquisition unit 17.

[0047] If visually impaired person information is acquired as the personal information of the facility user from the personal information acquisition unit 17, the visually impaired person determination unit 18 determines that the facility user is visually impaired. If type information is acquired as personal information of the facility user from the personal information acquisition unit 17, the visually impaired person determination unit 18 determines that the type of visual impairment of the facility user is the type indicated by the type information. The visually impaired person determination unit 18 outputs the determination result to each of the guidance image generation unit 14 and the voice output unit 16.

[0048] In the above-described second embodiment, the facility guidance device 2 is configured so that the personal information acquiring unit 17 acquires visually impaired information indicating that the facility user is visually impaired as the personal information of the facility user, and the visually impaired person determining unit 18 determines that the facility user is visually impaired if the visually impaired person information is acquired by the personal information acquiring unit 17. Therefore, if the facility user is a non-blind visually impaired person, the facility guidance device 2 can display a guidance image that is easy for the non-blind visually impaired person to see.

[0049] Embodiment 3 In the third embodiment, a facility guidance device 2 including an ambient sound collection unit 51 that collects ambient sounds around the location where a visually impaired person is located will be described.

[0050] Fig. 10 is a configuration diagram showing a facility guidance device 2 according to embodiment 3. In Fig. 10, the same reference numerals as in Fig. 1 and Fig. 8 indicate the same or corresponding parts, and detailed description thereof will be omitted. Fig. 11 is a hardware configuration diagram showing hardware of a facility guidance device 2 according to embodiment 3. In Fig. 11, the same reference numerals as in Fig. 2 and Fig. 9 indicate the same or corresponding parts, and detailed description thereof will be omitted. The facility guidance device 2 includes a registration reception unit 11, a personal information acquisition unit 12, a visually impaired person determination unit 13, a guidance image generation unit 14, an image display processing unit 15, an ambient sound collection unit 51, an obstructive sound generation unit 52 and an audio output unit 53.

[0051] The microphone 45 of the signage 3 collects sounds around the location of the facility user, and outputs collected sound data indicating the surrounding sounds to the surrounding sound collector 51. The ambient sound collecting unit 51 is realized by, for example, an ambient sound collecting circuit 61 shown in FIG. The ambient sound collection unit 51 collects collected sound data from the microphone 45 . The ambient sound collection unit 51 outputs the collected sound data to the obstructive sound generation unit 52 .

[0052] The obstruent sound generating unit 52 is realized by, for example, an obstruent sound generating circuit 62 shown in FIG. The obstructive sound generating unit 52 acquires collected sound data from the ambient sound collecting unit 51 . The obstructing sound generating unit 52 generates obstructing sound data indicating obstructing sounds that are sounds for reducing surrounding sounds indicated by the sound collection data. The obstructive sound generation unit 52 outputs the obstructive sound data to the audio output unit 53 .

[0053] The audio output unit 53 is realized by, for example, an audio output circuit 63 shown in FIG. The audio output unit 53 acquires the obstruent sound data from the obstruent sound generation unit 52 . The audio output unit 53 outputs audio data indicating the voice of the attendant to the speaker 44, and also outputs obstruction sound data to the speaker 44, thereby causing the speaker 44 to output an obstruction sound.

[0054] The facility guidance device 2 shown in Fig. 10 is obtained by applying the ambient sound collection unit 51, the obstructing sound generation unit 52, and the audio output unit 53 to the facility guidance device 2 shown in Fig. 1. However, this is merely an example, and the ambient sound collection unit 51, the obstructing sound generation unit 52, and the audio output unit 53 may be applied to the facility guidance device 2 shown in Fig. 8.

[0055] 10, it is assumed that each of the components of the facility guidance device 2, that is, the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the image display processing unit 15, the ambient sound collection unit 51, the obstructive sound generation unit 52, and the audio output unit 53, is realized by dedicated hardware as shown in Fig. 11. That is, it is assumed that the facility guidance device 2 is realized by the registration acceptance circuit 21, the personal information acquisition circuit 22, the visually impaired person determination circuit 23, the guidance image generation circuit 24, the image display processing circuit 25, the ambient sound collection circuit 61, the obstructive sound generation circuit 62, and the audio output circuit 63. Each of the registration reception circuit 21, personal information acquisition circuit 22, visually impaired person determination circuit 23, guidance image generation circuit 24, image display processing circuit 25, ambient sound collection circuit 61, obstruction sound generation circuit 62 and audio output circuit 63 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0056] The components of the facility guidance device 2 are not limited to those realized by dedicated hardware, and the facility guidance device 2 may be realized by software, firmware, or a combination of software and firmware. When the facility guidance device 2 is realized by software, firmware, or the like, a facility guidance program for causing a computer to execute the respective processing procedures in the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the image display processing unit 15, the ambient sound collection unit 51, the obstructive sound generation unit 52, and the audio output unit 53 is stored in the memory 31 shown in Fig. 3. Then, the processor 32 shown in Fig. 3 executes the facility guidance program stored in the memory 31.

[0057] 11 shows an example in which each of the components of the facility guidance device 2 is realized by dedicated hardware, while Fig. 3 shows an example in which the facility guidance device 2 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the facility guidance device 2 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0058] Next, the operation of the facility guidance device 2 shown in Fig. 10 will be described. However, since the facility guidance device 2 is the same as that shown in Fig. 1 except for the ambient sound collection unit 51, the obstructing sound generation unit 52, and the audio output unit 53, the operation of the ambient sound collection unit 51, the obstructing sound generation unit 52, and the audio output unit 53 will be mainly described here.

[0059] The microphone 45 of the signage 3 collects sounds around the location of the facility user, and outputs collected sound data indicating the surrounding sounds to the ambient sound collection unit 51 of the facility guide device 2. Examples of ambient sounds include the sounds of crowds, broadcast sounds from facilities, sounds of equipment installed in the facilities, and sounds of vehicles. The ambient sound collection unit 51 collects collected sound data from the microphone 45 . The ambient sound collection unit 51 outputs the collected sound data to the obstructive sound generation unit 52 .

[0060] The obstructive sound generating unit 52 acquires collected sound data from the ambient sound collecting unit 51 . The obstructing sound generating unit 52 generates obstructing sound data indicating obstructing sounds that are sounds for reducing surrounding sounds indicated by the sound collection data. An example of an obstructive sound is a sound that has an opposite phase to the surrounding sound indicated by the collected sound data. The process of generating the obstructive sound itself is a known technique, and therefore a detailed description thereof will be omitted. The obstructive sound generation unit 52 outputs the obstructive sound data to the audio output unit 53 .

[0061] The audio output unit 53 acquires the obstruent sound data from the obstruent sound generation unit 52 . The audio output unit 53 outputs audio data indicating the voice of the facility staff member to the speaker 44, and also outputs obstructive sound data to the speaker 44, thereby causing the speaker 44 to output obstructive sounds. The disturbing sound is output from the speaker 44, thereby reducing the sound around the location of the facility user. Therefore, even if the volume of the sound around the location of the facility user is high, the facility user can easily hear the voice of the staff member.

[0062] In the above-described third embodiment, the facility guidance device 2 is configured to include an ambient sound collection unit 51 that collects ambient sounds around the location where the facility user is present, and an obstrusive sound generation unit 52 that generates obstrusive sound data indicating obstrusive sounds that are sounds for reducing the ambient sounds collected by the ambient sound collection unit 51. Furthermore, the audio output unit 53 of the facility guidance device 2 outputs audio data indicating the voice of a facility staff member to the speaker 44, and also outputs obstrusive sound data to the speaker 44. Thus, the facility guidance device 2 can reduce the facility user's difficulty in hearing voices when the volume of the ambient sounds around the location where the facility user is present is high.

[0063] 10, the obstructing sound generating unit 52 generates obstructing sound data indicating obstructing sounds that are sounds for reducing the surrounding sounds collected by the surrounding sound collecting unit 51, and the audio output unit 53 outputs the obstructing sound data to the speaker 44. However, this is merely an example, and the audio output unit 53 may be configured to switch the volume of the voice of the staff member indicated by the audio data according to the volume of the surrounding sounds collected by the surrounding sound collecting unit 51. Specifically, the louder the volume of the surrounding sounds, the louder the voice output unit 53 outputs the volume of the voice of the staff from the speaker 44. In this case, the voice output unit 53 collects the surrounding sounds collected by the surrounding sound collection unit 51. In this way, facility guidance device 2 can reduce the difficulty that the facility user has in hearing voices when the volume of sounds around the facility user's location is high.

[0064] Embodiment 4 In the fourth embodiment, a facility guidance device 2 including a voice guidance data generating unit 54 that generates voice guidance data for providing voice guidance on the functions of operation switches 71a and 71b will be described.

[0065] Fig. 12 is an explanatory diagram showing the signage 3. In Fig. 12, the same reference numerals as in Fig. 4 denote the same or corresponding parts, and detailed description thereof will be omitted. The signage 3 shown in FIG. 12 further includes operation switches 71a and 71b and contact sensors 72a and 72b. Each of the operation switches 71a and 71b is a switch that receives operations from facility users. The contact sensor 72a is a sensor that detects contact of a facility user with the operation switch 71a. The contact sensor 72b is a sensor that detects contact of a facility user with the operation switch 71b.

[0066] 12, two operation switches 71a, 71b and two contact sensors 72a, 72b are provided on the signage 3. However, this is merely an example, and the number of operation switches provided on the signage 3 may be one, or three or more. Also, the number of contact sensors provided on the signage 3 may be one, or three or more.

[0067] Fig. 13 is a configuration diagram showing a facility guidance device 2 according to embodiment 4. In Fig. 13, the same reference numerals as those in Figs. 1, 8 and 10 indicate the same or corresponding parts, and detailed description thereof will be omitted.

[0068] The voice guidance data generating unit 54 is realized by, for example, a voice guidance data generating circuit 64 shown in FIG. The voice guidance data generating unit 54 generates voice guidance data for providing voice guidance on the function of the operation switch 71a when a contact is detected by the contact sensor 72a. The voice guidance data generating unit 54 generates voice guidance data for providing voice guidance on the function of the operation switch 71b when a contact is detected by the contact sensor 72b.

[0069] The audio output unit 55 is realized by, for example, an audio output circuit 65 shown in FIG. For example, when a visually impaired person operates switch 42 for calling an attendant, the audio output unit 55 outputs audio data indicating the voice of the facility attendant to the speaker 44, thereby outputting the voice of the facility attendant from the speaker 44. Moreover, the voice output unit 55 outputs the voice guidance data generated by the voice guidance data generating unit 54 to the speaker 44, thereby causing the speaker 44 to output a voice indicated by the voice guidance data.

[0070] The facility guidance device 2 shown in Fig. 13 is obtained by applying the voice guidance data generating unit 54 and the voice output unit 55 to the facility guidance device 2 shown in Fig. 1. However, this is merely an example, and the voice guidance data generating unit 54 and the voice output unit 55 may be applied to the facility guidance device 2 shown in Fig. 8 or the facility guidance device 2 shown in Fig. 10.

[0071] In Fig. 13, it is assumed that each of the components of the facility guidance device 2, that is, the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the image display processing unit 15, the voice guidance data generation unit 54, and the voice output unit 55, is realized by dedicated hardware as shown in Fig. 14. In other words, it is assumed that the facility guidance device 2 is realized by the registration acceptance circuit 21, the personal information acquisition circuit 22, the visually impaired person determination circuit 23, the guidance image generation circuit 24, the image display processing circuit 25, the voice guidance data generation circuit 64, and the voice output circuit 65. Each of the registration reception circuit 21, personal information acquisition circuit 22, visually impaired person determination circuit 23, guidance image generation circuit 24, image display processing circuit 25, voice guidance data generation circuit 64 and voice output circuit 65 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0072] The components of the facility guidance device 2 are not limited to those realized by dedicated hardware, and the facility guidance device 2 may be realized by software, firmware, or a combination of software and firmware. When the facility guidance device 2 is realized by software, firmware, or the like, a facility guidance program for causing a computer to execute the respective processing procedures of the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the image display processing unit 15, the voice guidance data generation unit 54, and the voice output unit 55 is stored in the memory 31 shown in Fig. 3. Then, the processor 32 shown in Fig. 3 executes the facility guidance program stored in the memory 31.

[0073] 14 shows an example in which each of the components of the facility guidance device 2 is realized by dedicated hardware, while Fig. 3 shows an example in which the facility guidance device 2 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the facility guidance device 2 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0074] Next, the operation of the facility guidance device 2 shown in Fig. 13 will be described. However, since the facility guidance device 2 shown in Fig. 1 is the same as that shown in Fig. 1 except for the voice guidance data generating unit 54 and the voice output unit 55, the operation of the voice guidance data generating unit 54 and the voice output unit 55 will be mainly described here.

[0075] When a facility user stands in front of the signage 3 and touches the operation switch 71a, the contact sensor 72a detects the facility user's contact with the operation switch 71a, and outputs a contact detection signal Sa to the voice guidance data generator . When the facility user touches the operation switch 71b, the contact sensor 72b detects the facility user's contact with the operation switch 71b, and outputs a contact detection signal Sb to the voice guidance data generator .

[0076] When the voice guidance data generating unit 54 receives a contact detection signal Sa from the contact sensor 72a, it generates voice guidance data Ga for providing voice guidance on the function of the operation switch 71a. The voice guidance data generating unit 54 outputs the voice guidance data Ga to the voice output unit 55. If the function of the operation switch 71a is, for example, to accept a request for displaying a map of the inside of a facility, voice guidance data Ga indicating that the request for displaying a map of the inside of the facility is accepted is generated. When the voice guidance data generating unit 54 receives a contact detection signal Sb from the contact sensor 72b, it generates voice guidance data Gb for providing voice guidance on the function of the operation switch 71b. The voice guidance data generating unit 54 outputs the voice guidance data Gb to the voice output unit 55 . If the function of the operation switch 71b is, for example, to accept a request to display a route map, voice guidance data Gb indicating that the request to display a route map is accepted is generated.

[0077] When the voice output unit 55 acquires the voice guidance data Ga from the voice guidance data generation unit 54, the voice output unit 55 outputs the voice guidance data Ga to the speaker 44, thereby causing the speaker 44 to output a voice indicated by the voice guidance data Ga. When the voice output unit 55 acquires the voice guidance data Gb from the voice guidance data generating unit 54, the voice output unit 55 outputs the voice guidance data Gb to the speaker 44, thereby causing the speaker 44 to output a voice indicated by the voice guidance data Gb.

[0078] In the above-described fourth embodiment, the signage 3 is provided with operation switches 71a and 71b that receive operations by the facility user, and contact sensors 72a and 72b that detect contact of the facility user with the operation switches 71a and 71b. The facility guidance device 2 is configured to include a voice guidance data generating unit 54 that generates voice guidance data for providing voice guidance on the functions of the operation switches 71a and 71b when contact is detected by the contact sensors 72a and 72b, and a voice output unit 55 that outputs the voice guidance data generated by the voice guidance data generating unit 54 to the speaker 44. Thus, the facility guidance device 2 can inform the facility user of the functions of the operation switches 71a and 71b.

[0079] Embodiment 5. In the fifth embodiment, a facility guidance device 2 including an explanation image generating unit 56 that generates an explanation image showing the functions of operation switches 71a and 71b will be described.

[0080] Fig. 15 is a configuration diagram showing a facility guidance device 2 according to embodiment 5.

[0081] The explanation image generating unit 56 is realized by, for example, an explanation image generating circuit 66 shown in FIG. The explanation image generating unit 56 generates an explanation image indicating the function of the operation switch 71a when the contact is detected by the contact sensor 72a. The explanation image generating unit 56 generates an explanation image indicating the function of the operation switch 71b when the contact is detected by the contact sensor 72b.

[0082] The image display processing unit 57 is realized by, for example, an image display processing circuit 67 shown in FIG. The image display processing unit 57 causes the guide image generated by the guide image generating unit 14 to be displayed on the display 43 of the signage 3. In addition, the image display processing unit 57 causes the explanatory image generated by the explanatory image generating unit 56 to be displayed on the display 43 of the signage 3.

[0083] In the facility guidance device 2 shown in Fig. 15, the explanatory image generation unit 56 and the image display processing unit 57 are each applied to the facility guidance device 2 shown in Fig. 1. However, this is merely an example, and the explanatory image generation unit 56 and the image display processing unit 57 may each be applied to the facility guidance device 2 shown in Fig. 8, the facility guidance device 2 shown in Fig. 10, or the facility guidance device 2 shown in Fig. 13.

[0084] In Fig. 15, it is assumed that each of the components of the facility guidance device 2, that is, the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guide image generation unit 14, the explanatory image generation unit 56, the image display processing unit 57, and the voice output unit 16, is realized by dedicated hardware as shown in Fig. 16. In other words, it is assumed that the facility guidance device 2 is realized by the registration acceptance circuit 21, the personal information acquisition circuit 22, the visually impaired person determination circuit 23, the guide image generation circuit 24, the explanatory image generation circuit 66, the image display processing circuit 67, and the voice output circuit 26. Each of the registration reception circuit 21, personal information acquisition circuit 22, visually impaired person determination circuit 23, guidance image generation circuit 24, explanatory image generation circuit 66, image display processing circuit 67 and audio output circuit 26 corresponds to, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0085] The components of the facility guidance device 2 are not limited to those realized by dedicated hardware, and the facility guidance device 2 may be realized by software, firmware, or a combination of software and firmware. When the facility guidance device 2 is realized by software, firmware, or the like, a facility guidance program for causing a computer to execute the respective processing procedures of the registration acceptance unit 11, the personal information acquisition unit 12, the visually impaired person determination unit 13, the guidance image generation unit 14, the explanation image generation unit 56, the image display processing unit 57, and the voice output unit 16 is stored in the memory 31 shown in Fig. 3. Then, the processor 32 shown in Fig. 3 executes the facility guidance program stored in the memory 31.

[0086] 16 shows an example in which each of the components of the facility guidance device 2 is realized by dedicated hardware, while Fig. 3 shows an example in which the facility guidance device 2 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the facility guidance device 2 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0087] Next, the operation of the facility guidance device 2 shown in Fig. 15 will be described. However, since the facility guidance device 2 shown in Fig. 1 is the same as that shown in Fig. 1 except for the explanation image generation unit 56 and the image display processing unit 57, the operation of the explanation image generation unit 56 and the image display processing unit 57 will be mainly described here.

[0088] When a facility user stands in front of the signage 3 and touches the operation switch 71a, the contact sensor 72a detects the facility user's contact with the operation switch 71a and outputs a contact detection signal Sa to the explanation image generation unit 56. When a facility user touches the operation switch 71b, the contact sensor 72b detects the facility user's contact with the operation switch 71b, and outputs a contact detection signal Sb to the explanation image generating unit 56.

[0089] When the explanation image generating unit 56 receives a contact detection signal Sa from the contact sensor 72a, it generates an explanation image Ea indicating the function of the operation switch 71a. The explanation image generating unit 56 outputs the explanation image Ea to the image display processing unit 57. If the function of the operation switch 71a is, for example, to accept a request for displaying a map of the inside of a facility, an explanation image Ea indicating that a request for displaying a map of the inside of the facility is accepted is generated. When the explanation image generating unit 56 receives a contact detection signal Sb from the contact sensor 72b, it generates an explanation image Eb indicating the function of the operation switch 71b. The explanation image generating unit 56 outputs the explanation image Eb to the image display processing unit 57. If the function of the operation switch 71b is, for example, to accept a request to display a route map, an explanation image Eb indicating that a request to display a route map is accepted is generated.

[0090] The image display processing unit 57 causes the guide image generated by the guide image generating unit 14 to be displayed on the display 43 of the signage 3. Furthermore, when the image display processing unit 57 acquires the explanation image Ea from the explanation image generating unit 56, the image display processing unit 57 causes the display 43 to display the explanation image Ea. When the image display processing unit 57 acquires the explanation image Eb from the explanation image generating unit 56, the image display processing unit 57 causes the display 43 to display the explanation image Eb.

[0091] In the above-described fifth embodiment, the signage 3 is provided with operation switches 71a and 71b that receive operations from the facility user, and contact sensors 72a and 72b that detect contact of the facility user with the operation switches 71a and 71b. The facility guidance device 2 is configured to include an explanatory image generator 56 that generates an explanatory image indicating the function of the operation switches 71a and 71b when contact is detected by the contact sensors 72a and 72b. Therefore, the facility guidance device 2 can inform the facility user of the functions of the operation switches 71a and 71b.

The personal information transmitting unit 58 transmits the personal information acquired by the personal information acquiring unit 12 to the information processing device 4 via a wireless line or a wired line.

[0095] The guide image receiving unit 59 is realized by, for example, a guide image receiving circuit 69 shown in FIG. The guide image receiving unit 59 receives a guide image of the facility from the information processing device 4 after the information processing device 4 has determined whether or not the facility user is a non-total-blind visually impaired person based on the personal information. The facility guidance image is a guidance image for visually impaired people that is generated when a facility user is determined to be a non-total blind visually impaired person, or a guidance image for non-visually impaired people that is generated when a facility user is determined to be a non-visually impaired person. The guidance image receiving unit 59 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the image display processing unit 60.

[0096] The image display processing unit 60 is realized by, for example, an image display processing circuit 70 shown in FIG. The image display processing unit 60 causes the guide image received by the guide image receiving unit 59 to be displayed on the display 43 of the signage 3 .

[0104] The visually impaired person determination unit 83 is realized by, for example, a visually impaired person determination circuit 93 shown in FIG. The visually impaired person determination unit 83 acquires personal information of the facility user from the personal information receiving unit 82. The visually impaired person determination unit 83, like the visually impaired person determination unit 13 shown in FIG. 1, determines whether or not the facility user is visually impaired based on personal information. The visually impaired person determination unit 83 determines that the type of visual impairment of the facility user is one that has been accepted for registration by the registration acceptance unit 81. The visually impaired person determination unit 83 outputs the determination result to the guidance image generation unit 84.

[0105] The guide image generating unit 84 is realized by, for example, a guide image generating circuit 94 shown in FIG. The guidance image generating unit 84 acquires the determination result from the visually impaired person determining unit 83 . If the visually impaired person determination unit 83 determines that the facility user is a visually impaired person who is not completely blind, the guidance image generation unit 84 generates a guidance image for visually impaired people as a guidance image for the facility. When the type of visual impairment is determined by the visually impaired person determination unit 83, the guidance image generation unit 84 generates a guidance image for the visually impaired person according to the type of visual impairment. If the visually impaired person determination unit 83 determines that the facility user is not visually impaired, the guidance image generation unit 84 generates a guidance image for non-visually impaired people as a guidance image for the facility. The guidance image generating unit 84 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the guidance image transmitting unit 85.

[0106] The guide image transmitting unit 85 is realized by, for example, a guide image transmitting circuit 95 shown in FIG. The guide image transmission unit 85 acquires a guide image for the visually impaired or a guide image for the non-visually impaired from the guide image generation unit 74. The guide image transmission unit 85 transmits the acquired guide image to the facility guide device 2 via a wireless line or a wired line.

[0107] In Fig. 19, it is assumed that each of the components of the information processing device 4, that is, the registration acceptance unit 81, the personal information receiving unit 82, the visually impaired person determination unit 83, the guide image generation unit 84, and the guide image transmission unit 85, is realized by dedicated hardware as shown in Fig. 20. That is, it is assumed that the information processing device 4 is realized by the registration acceptance circuit 91, the personal information receiving circuit 92, the visually impaired person determination circuit 93, the guide image generation circuit 94, and the guide image transmission circuit 95. Each of the registration acceptance circuit 91, the personal information receiving circuit 92, the visually impaired person determination circuit 93, the guidance image generation circuit 94 and the guidance image transmission circuit 95 may be, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC, an FPGA, or a combination of these.

[0108] The components of the information processing device 4 are not limited to those realized by dedicated hardware, and the information processing device 4 may be realized by software, firmware, or a combination of software and firmware. FIG. 21 is a hardware configuration diagram of a computer in the case where the information processing device 4 is realized by software, firmware, or the like. When the information processing device 4 is realized by software, firmware, or the like, an information processing program for causing a computer to execute the respective processing procedures of the registration acceptance unit 81, the personal information receiving unit 82, the visually impaired person determination unit 83, the guide image generation unit 84, and the guide image transmission unit 85 is stored in the memory 101.

[0109] 20 shows an example in which each of the components of the information processing device 6 is realized by dedicated hardware, and Fig. 21 shows an example in which the information processing device 6 is realized by software, firmware, etc. However, this is merely an example, and some of the components in the information processing device 4 may be realized by dedicated hardware, and the remaining components may be realized by software, firmware, etc.

[0110] Next, the operation of the facility guidance device 2 shown in FIG. 17 and the operation of the information processing device 4 shown in FIG. 19 will be described. When a visually impaired person uses a facility, the visually impaired person needs to register his / her personal information in advance in the information processing device 4. However, when the personal information acquiring unit 12 of the facility guidance device 2 acquires each of the visually impaired person information and the type information as the personal information of the facility user, it is not necessary to register the personal information in the information processing device 4 in advance. A visually impaired person operates the user terminal 1 to capture an image of his or her own face. The visually impaired person also operates the user terminal 1 to input the type of visual impairment. The user terminal 1 transmits, to the information processing device 4, personal information of the visually impaired person, including face image data showing a face image of the visually impaired person and type information showing the type of visual impairment.

[0111] The registration acceptance unit 81 of the information processing device 4 receives the personal information of the visually impaired person transmitted from the user terminal 1. Similar to the registration reception unit 11 shown in FIG. 1, the registration reception unit 81 accepts the registration of a facial image of a visually impaired person indicated by facial image data included in the personal information of the visually impaired person, and the type of visual impairment indicated by type information included in the personal information.

[0112] When a facility user stands in front of the signage 3, the camera 41 of the signage 3 captures an image of the facility user's face. Personal information acquiring unit 12 of facility guidance device 2 acquires a facial image of the facility user captured by camera 41 as personal information of the facility user. The personal information acquiring unit 12 outputs the facial image of the facility user to the personal information transmitting unit 58 as the facility user's personal information.

[0113] The personal information transmitting unit 58 of the facility guidance device 2 transmits the personal information acquired by the personal information acquiring unit 12 to the information processing device 4 via a wireless line or a wired line. Personal information receiving unit 82 of information processing device 4 receives the personal information of the facility user transmitted from facility guidance device 2. The personal information receiving unit 82 outputs the personal information of the facility user to the visually impaired person determining unit 83.

[0114] The visually impaired person determination unit 83 of the information processing device 4 acquires personal information of the facility user from the personal information receiving unit 82. The visually impaired person determination unit 83 compares the face image of the visually impaired person whose registration has been accepted by the registration acceptance unit 81 with the face image of the facility user, which is the personal information of the facility user. The visually impaired person determination unit 83 determines that the facility user is visually impaired if the facial image of the facility user is present among the facial images of visually impaired people whose registration has been accepted by the registration acceptance unit 81. Furthermore, the visually impaired person determination unit 83 determines that the type of visual impairment of the facility user is one that has been accepted for registration by the registration acceptance unit 81.

[0115] If the facial image of the facility user is not present among the facial images of visually impaired people whose registration has been accepted by the registration acceptance unit 81, the visually impaired person determination unit 83 determines that the facility user is not visually impaired. The visually impaired person determination unit 83 outputs the determination result to the guidance image generation unit 84. If the personal information of the facility user includes visually impaired information, the visually impaired person determination unit 83 determines that the facility user is visually impaired. If the personal information of the facility user includes type information, the visually impaired person determination unit 83 determines that the type of visual impairment of the facility user is the type indicated by the type information.

[0116] The guidance image generating unit 84 of the information processing device 4 acquires the determination result from the visually impaired person determining unit 83. If the visually impaired person determination unit 83 determines that a facility user is a non-totally blind visually impaired person, the guidance image generation unit 84 generates a guidance image for visually impaired people, similar to the guidance image generation unit 14 shown in Figure 1. When the type of visual impairment is determined by the visually impaired person determination unit 83, the guidance image generation unit 84 generates a guidance image for the visually impaired person according to the type of visual impairment, similar to the guidance image generation unit 14 shown in Figure 1. If the visually impaired person determination unit 83 determines that the facility user is not visually impaired, the guidance image generation unit 84 generates a guidance image for non-visually impaired people, similar to the guidance image generation unit 14 shown in Figure 1. The guidance image generating unit 84 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the guidance image transmitting unit 85.

[0117] The guide image transmission unit 85 of the information processing device 4 acquires, from the guide image generation unit 74, a guide image for visually impaired people or a guide image for non-visually impaired people. When the guidance image transmission unit 85 acquires a guidance image for visually impaired persons from the guidance image generation unit 74, the guidance image transmission unit 85 transmits the guidance image for visually impaired persons to the facility guidance device 2 via a wireless line or a wired line. When the guidance image transmission unit 85 obtains a guidance image for non-visually impaired persons from the guidance image generation unit 74, it transmits the guidance image for non-visually impaired persons to the facility guidance device 2 via a wireless line or a wired line.

[0118] The guidance image receiving unit 59 of the facility guidance device 2 receives from the information processing device 4 a guidance image for visually impaired people or a guidance image for non-visually impaired people. The guidance image receiving unit 59 outputs a guidance image for visually impaired people or a guidance image for non-visually impaired people to the image display processing unit 60.

[0119] The image display processing unit 60 of the facility guidance device 2 acquires from the guidance image receiving unit 59 a guidance image for visually impaired people or a guidance image for non-visually impaired people. When the image display processing unit 60 acquires a guidance image for visually impaired persons, the image display processing unit 60 causes the display 43 of the signage 3 to display the guidance image for visually impaired persons. When the image display processing unit 60 acquires a guidance image for non-visually impaired persons, the image display processing unit 60 causes the display 43 of the signage 3 to display the guidance image for non-visually impaired persons.

[0120] In the above-described sixth embodiment, the facility guidance device 2 is configured to include the personal information acquisition unit 12 that acquires personal information of the facility user, and the personal information transmission unit 58 that transmits the personal information acquired by the personal information acquisition unit 12 to the information processing device 4. The facility guidance device 2 also includes a guidance image receiving unit 59 that receives, as a guidance image for the facility, a guidance image for visually impaired people that is generated when the facility user is determined to be a non-blind visually impaired person, or a guidance image for non-visually impaired people that is generated when the facility user is determined to be a non-blind visually impaired person, from the information processing device 4 after the information processing device 4 determines whether the facility user is a non-blind visually impaired person based on the personal information. Therefore, if the facility user is a non-blind visually impaired person, the facility guidance device 2 can display a guidance image that is easy for the non-blind visually impaired person to see.
