Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The figures are only shown schematically to provide a thorough understanding of the invention. Therefore, the present invention is not limited to the illustrated example. In each figure, common or similar components are designated by the same reference numerals, and their overlapping explanations will be omitted.

<About the configuration of the dental treatment system according to the embodiment>
The configuration of a dental treatment system 1 according to an embodiment will be described with reference to FIGS. 1 and 2. The dental treatment system 1 is a system for performing dental treatment. In the dental treatment system 1, fictitious (virtual space) characters (referred to as "virtual characters") that are represented in a computer are used to represent patients, their attendants (family members, caregivers, etc.), and treatment staff (dentists, caregivers, etc.). One-way or two-way information transmission to at least one of the dental hygienists, assistants, etc.). A patient attendant is a patient information provider who provides patient information to medical staff on behalf of the patient, such as a patient's family or a person who accompanies the patient to protect and care for the patient. The virtual character may, for example, address the patient or an attendant. The virtual character also interacts with the patient by asking questions of the patient and the attendant and obtaining answers. Note that in the embodiments, the explanation will focus on information transmission to patients and medical staff, and references to the patient's attendants may be omitted. However, this does not preclude the transmission of information to the patient's attendant.

The virtual character may be a three-dimensional (3D) or two-dimensional (2D) representation. The character that transmits information may be not only a living entity but also a non-living entity imitating a living entity (pseudo-living entity). The virtual character transmits information to the patient using, for example, characters on a screen or sounds output from a speaker.

The living entity may be, for example, a human being, a non-human animal, a plant, a fungus, etc., regardless of whether or not it is actually capable of dialogue. Furthermore, the living entity may be an imaginary creature (for example, a fairy, etc.). The pseudo-living entity may be, for example, not only a humanoid or a non-human animal-shaped robot, but also any entity that the patient can recognize as a provider who transmits information. Pseudo life forms include, for example, things that make up the human body (e.g., teeth, bones, mouth, etc.), natural structures (e.g., planets, mountains, etc.), artificial structures (including buildings), vehicles, and tools. (for example, a toothbrush, a cup, etc.), a natural phenomenon (for example, water, fire, wind, clouds, etc.), or a geometric figure (for example, a sphere, a polyhedron, etc.).

When the character is a pseudo-living entity, it is preferable that the character be devised so that the patient can recognize it as a provider who is transmitting information. Such devices include, for example, adding a face to the pseudo-living entity, changing the movements and facial expressions (gestures) performed by the pseudo-living entity, changing the shape and color of the pseudo-living entity, and expressing luminescence. . Furthermore, when the words uttered by the virtual character are displayed as characters on the screen, the device may be one that associates the characters on the screen with the virtual character (for example, a speech bubble expression). It would be good to have a similar idea in the case of a living creature with which the character cannot actually interact.

The virtual character is displayed on any of the devices (components) constituting the dental treatment system 1, and is capable of addressing and interacting with patients and treatment staff. The virtual character may give predetermined responses (questions and answers) by a pre-created program (including artificial intelligence (AI)), and in that case, unattended responses to the patient may be possible. be. Furthermore, the virtual character may be one that makes arbitrary responses (questions and answers) when operated by a human (for example, medical staff), and in that case, the virtual character may also be called an alter ego (such as an "avatar") of the human being operated by the character. It is possible to respond by being called). When the dental treatment system 1 has a plurality of display sections, the virtual character may be displayed by moving among these display sections.

The content of the information that the virtual character communicates with patients and clinical staff (transfer information) is similar to what clinical staff do with patients in conventional dental care (e.g., greetings and dialogue). It may be. The transmitted information is preferably information that contributes to reducing opportunities for face-to-face encounters between patients and medical staff, information that aims to make effective use of patient waiting time, and the like. Furthermore, the transmitted information may be appropriate for the dental treatment situation, and may be information that allows the patient to receive treatment with peace of mind.

Information to be transmitted during the waiting period before treatment includes, for example, content to elicit the patient's chief complaint, content to elicit information about the patient's biological body, content to elicit information about past treatments, content related to interviews, and content related to medical treatment. , content related to the indoor environment in which medical treatment is performed, content to help patients relax, and other content to facilitate smooth treatment. In addition, information to be communicated during the post-treatment counseling period includes, for example, content related to self-pay/insurance medical treatment, content related to town information through regional cooperation, content related to sales of home care products, content related to periodontal disease prevention, and content related to continued medical treatment. This includes information on how to receive counseling, and other information related to counseling.

As shown in FIG. 1, the dental treatment system 1 according to the present embodiment mainly includes a patient chair 2, a lighting section 3 (see FIG. 2), an imaging section 4, a display section 5, and an audio input section 6. , an audio output section 7, a first treatment table section 10, a second treatment table section 20, a spittoon unit 30, a foot controller 41, and a computer 50 (see FIG. 2).

Be prepared. Note that in FIG. 3, the instrument 12 is omitted.

The instrument 12 is, for example, an air turbine handpiece, a micromotor handpiece, a scaler, a three-way syringe, a vacuum syringe, or the like. The air turbine handpiece is a type of dental turbine handpiece, and grinds teeth by rotating a cutting tool at high speed using the force of compressed air while injecting water. The micromotor handpiece is a type of dental turbine handpiece that grinds teeth by rotating a cutting tool at high speed using the power of an electric motor while injecting water. The instrument 12 is not limited to these, and may be an intraoral camera, a photopolymerization irradiator, a root canal length measuring device, a root canal expander, etc., and may be a non-driven instrument such as a mirror or a syringe. Good too. The instrument 12 is stored while being held by an instrument hanger 16.

The display unit 13 is, for example, a liquid crystal display. Information regarding the dental treatment system 1 is displayed on the display unit 13.
The operation unit 14 is composed of, for example, a plurality of operation buttons. By operating the operating unit 14, the components constituting the dental treatment system 1 can be operated.

The non-contact input unit 15 has a function of displaying an image (for example, an image of an operation screen or an image including a virtual character) in the air, and detecting an input operation on the image displayed in the air. The non-contact input section 15 is an example of an "information transmission section." The non-contact input unit 15 of this embodiment is installed by being fixed to the first treatment table part 10, but components other than the first treatment table part 10 (for example, the second treatment table part 20, spittoon unit 30, patient chair 2, lighting section 3, photographing section 4, etc.) may be provided with a non-contact input section 15. Further, the non-contact input section 15 may be provided in a detachable manner. For example, the non-contact input section 15 may be fixed or detachably provided with an auxiliary arm. FIG. 4 shows a schematic configuration of the non-contact input section 15.

As shown in FIG. 4, the non-contact input section 15 includes a flat display 151 (display section) and a light imaging section 152 arranged apart from the display 151. The display 151 is embedded within the medical table 11. The optical imaging unit 152 is installed at an angle α of 30 to 60 degrees with respect to the display 151, receives the image displayed on the display 151, and converts the image on the display 151 into a first real image 153 at a symmetrical position. imaged as. The optical imaging section 152 is arranged, for example, on the back surface of a glass plate that constitutes the medical treatment table 11, so as to overlap the glass plate. As a result, the surface of the medical table 11 has no unevenness, making it easy to place items on the surface of the medical table 11.

The optical imaging section 152 has flat light control panels 154 and 155 that are arranged on one side in contact with or in close proximity to each other. The light control panels 154 and 155 are mainly made of a transparent material such as glass or transparent plastic, and have a large number of band-shaped planar light reflecting parts installed therein. The planar light reflecting portions are, for example, metal sheets, vapor-deposited metals, mirror sheets, etc. with good reflection efficiency, and are arranged perpendicularly to one surface at a constant pitch. The planar light reflecting section of the light control panel 154 and the planar light reflecting section of the light control panel 155 are arranged to intersect (for example, orthogonally) in plan view.

The display 151 (display section) is, for example, a liquid crystal type display, has a liquid crystal section and a backlight, and has a structure in which a large number of cells (light-emitting blocks) are arranged in a grid. Each cell has an RGB light emitting section, an infrared light emitting section, an infrared sensor, and a band-shaped transparent electrode. The RGB light emitting section is a section that emits R (red), G (green), and B (blue) light when the light from the backlight passes through the liquid crystal section, and may be a color filter. The liquid crystal section has a well-known structure, and is supplied with power by band-shaped transparent electrodes arranged in a grid pattern in the X and Y directions at the top and bottom, respectively, and can control the light-shielding state and the light-transmitting state on a cell-by-cell basis. Above and below the infrared sensor, band-shaped transparent electrodes that obtain optical signals from the infrared sensor (and sometimes supply power) are arranged in a grid pattern above and below.

The operation of the display 151 (display section) will be explained. When the backlight is turned on and the liquid crystal part corresponding to the RGB light emitting part and infrared light emitting part in each cell (i.e. directly below) is turned on and off via the transparent electrode, visible light and infrared light are generated from the cell. do. As a result, an image can be formed on the display 151, and infrared rays with uniform illuminance are generated from the display 151. As shown in FIG. 4, light (r1 to r4) from the image displayed on the display 151 enters the optical imaging section 152, and a first real image 153 is formed on the opposite side. Note that the display 151 and the first real image 153 are formed laterally or vertically symmetrically with the optical imaging section 152 as the center. In this case, the infrared rays emitted from the infrared light emitting part of the display 151 are formed in a planar shape overlapping the position of the first real image 153, but cannot be visually recognized.

Here, as shown in FIG. 4, when a finger 158 (a touch pen, pointer stick, etc. may be used) is inserted into a predetermined position of the first real image 153, infrared reflected light is generated from the finger 158, and the image is A second real image 159 is formed on the display 151 side (that is, on the display 151) via the image section 152. As shown in FIG. 4, the infrared reflected light from the finger 158 enters the optical imaging unit 152 on the return path indicated by symbols s1 and s3, is bent and reflected by the optical imaging unit 152, and is reflected by symbols s2 and s4. A second real image 159 is formed through the return path shown by . The second real image 159 is formed using infrared rays and cannot be visually observed. In FIG. 4, the symbol β indicates that the first real image 153 and the second real image 159 are formed symmetrically with respect to the optical imaging section 152. Note that symbols r1 to r4 and s1 to s4 indicate infrared rays on the outside of the infrared beam contributing to image formation.

Then, the infrared sensor arranged in each cell of the display 151 detects an infrared image (second real image 159) of the finger 158, and thereby it is possible to detect which part of the first real image 153 is pressed. The infrared sensor is an example of a "detection unit" that detects a designated position in a formed image. If the first real image 153 is, for example, an image of an operation screen for operating a device, the operating position of the operation screen can be detected. Note that the non-contact input section 15 is made to function as a display section that displays an image in the air by stopping the operation of the infrared light emitting section of the display 151 and the infrared sensor, and by not using the detection results of the infrared sensor for control. You can also do that.

Note that the display 151 may have a configuration in which the infrared light emitting section and the infrared sensor are not included (that is, the infrared light emitting section and the infrared sensor may be installed separately from the display 151). For example, a line sensor in which an infrared light emitting unit and an infrared sensor are arranged in a straight line is used to detect which part of the first real image 153 is pointed. The line sensor is arranged, for example, on an extension of the first real image 153 so that the first real image 153 and the detection surface of the line sensor are on the same plane. The line sensor irradiates infrared rays so as to match the plane of the first real image 153, receives the reflected light that is reflected by a finger 158, etc., and detects the coordinates of the first real image 153. do. Further, for example, an infrared light emitting section may be arranged so as to irradiate the screen of the display 151 with infrared light. Then, the first real image 153 may be photographed using an infrared camera that detects only infrared rays, and from the result, it may be detected which part of the first real image 153 is indicated. Note that the infrared light emitting unit may be one that scans the first real image 153 or the screen of the display 151.

In this embodiment, the non-contact input unit 15 mainly displays the operation screen in the air during the treatment time period. That is, during this time period, the non-contact input section 15 is mainly operated by the dentist and is used as an operation section for operating the device. Furthermore, during the time period when no treatment is being performed, the non-contact input unit 15 mainly displays a screen containing virtual characters in the air. The virtual character provides information to the patient, obtains information from the patient, and interacts with the patient, for example. That is, during this time period, the non-contact input unit 15 is mainly viewed by the patient and is used as an information transmission unit that transmits information to the patient in one or two directions. Therefore, it is preferable that the non-contact input section 15 be installed at a position where it can easily be seen by the patient. Specifically, the non-contact input unit 15 is preferably placed on the side of the medical table 11 that is closer to the patient. Details of information transmission using the non-contact input unit 15 will be described later.

The second treatment table section 20 is provided with a handle 20b, and the dental hygienist grips the handle 20b to adjust the position of the second treatment table section 20.

The instrument 22 is, for example, a triple syringe, a vacuum, a saliva removal device, or the like. The triple syringe is an instrument for cleaning the inside of the oral cavity with a spray or drying it with compressed air to make it easier to observe the surgical field. A vacuum is used to suction and remove cutting dust, water, saliva, etc. from the oral cavity in order to ensure the surgeon's field of vision and maintain oral hygiene. The saliva evacuation device is used to suction and remove saliva, water, and cleaning fluid that have accumulated in the oral cavity in order to dehumidify the treatment area and ensure the surgeon's field of vision. The instrument 22 is stored while being held by the instrument hanger 16. The operation unit 23 is composed of, for example, a plurality of operation buttons.

The spittoon unit 30 shown in FIG. 1 is a device for a patient to gargle. The spittoon unit 30 includes, for example, a water supply section 31 and a spittoon 32.

When the screen transitions to screen 90, the operation screen 80 is displayed.

The information transmission control unit 52 controls one-way or two-way information transmission to at least one of the patient, the patient's attendant, and the medical staff. The information transfer control section 52 includes, for example, a first information transfer control section 52a and a second information transfer control section 52b. The information transmission control section 52 transmits information via the information transmission section.

The first information transmission control unit 52a performs one-way or two-way information transmission using a virtual character. The first information transmission control section 52a, for example, displays a virtual character on the non-contact input section 15 (information transmission section), and performs one-way or two-way information transmission to the patient and attendant via the virtual character. The first information transmission control unit 52a causes, for example, a virtual character (an avatar of a medical staff member or an artificial intelligence (AI)) to address or have a dialogue with the patient or an attendant. For example, the first information transmission control unit 52a may cause the virtual character to call out to you or others based on the facial expressions and gestures of the virtual character displayed on the non-contact input unit 15, the characters on the screen, the voice output from the audio output unit 7, etc. Make the patient and attendant aware that a dialogue is taking place. The first information transmission control unit 52a inputs the patient's or attendant's voice via the voice input unit 6, thereby receiving information transmitted from the patient or attendant (for example, a response in a call or dialogue). get. Note that the first information transmission control unit 52a may update the transmission information (messages, advertisements, etc. to be transmitted to the patient and attendants) to be transmitted to the patient and attendants according to instructions from the medical staff. Furthermore, the medical staff may be able to create the communication information.

Information transmission control using a virtual character by the first information transmission control section 52a will be described with reference to FIGS. 7 to 9. 7 to 9 are examples of screens used to convey information to patients using virtual characters.

The character screens 70A to 70C shown in FIG. 7 are intended to bring out the chief complaint before treatment. Here, it is assumed that the character screens 70A to 70C shown in FIG. 7 are displayed continuously, but any one of the character screens 70A to 70C may be displayed.
The character screen 70A shown in FIG. 7A includes a virtual character 71A with a pained expression and a comment 72A saying "pain".
The character screen 70B shown in FIG. 7(b) includes a virtual character 71B with a melancholy expression and a comment 72B that reads "Oral troubles."
The character screen 70C shown in FIG. 7(c) includes a virtual character 71C with an exhilarating facial expression and a comment 72C that says, "Please say hello."
By showing these character screens 70A to 70C to the patient before treatment, it is possible to elicit the patient's chief complaint without the medical staff having to directly address the patient.

The character screens 70D and 70E shown in FIG. 8 are intended to help patients receive treatment with peace of mind. Although it is assumed here that the character screens 70D and 70E shown in FIG. 8 are displayed consecutively, either of the character screens 70D and 70E may be displayed.
The character screen 70D shown in FIG. 8(a) includes a virtual character 71D with a relaxed expression and a comment 72D saying "relax".
The character screen 70E shown in FIG. 8(b) includes a virtual character 71E making a request gesture and a comment 72E saying "Please wait."
By showing these character screens 70D and 70E to the patient before treatment, it is possible to relieve the patient's sense of anxiety without the need for the medical staff to directly address the patient.

The character screens 70F and 70G shown in FIG. 9 are intended to provide useful information to patients (that toothbrushes can be sold). Although it is assumed here that the character screens 70F and 70G shown in FIG. 9 are displayed consecutively, either of the character screens 70F and 70G may be displayed.
The character screen 70F shown in FIG. 9(a) includes a virtual character 71F with a speaking gesture and a comment 72F saying "Perfect toothbrush."
The character screen 70G shown in FIG. 9(b) includes a virtual character 71G holding a toothbrush and a comment 72G saying "I can guide you."
By showing these character screens 70F and 70G to the patient before and after treatment, the medical staff can provide useful information to the patient without having to directly address the patient.

Note that the first information transmission control unit 52a displays, for example, medical questionnaires and questionnaires together with the virtual characters on the non-contact input unit 15 (information transmission unit) other than the character screen 70 shown in FIGS. The virtual character may be controlled to prompt input. Further, the first information transmission control unit 52a may realize a videophone conversation with the patient via a virtual character.

Other functions of the first information transmission control section 52a will be explained with reference to FIG. 5. The first information transmission control section 52a, for example, displays a virtual character on the non-contact input section 15 (information transmission section), and performs one-way or two-way information transmission to the medical staff in the examination room via the virtual character. The information transmission control unit 52 causes, for example, a virtual character (an avatar of a medical staff member outside the examination room or an artificial intelligence (AI)) to address or interact with the medical staff member inside the examination room. For example, the first information transmission control unit 52a transmits information regarding treatment (for example, patient Convey biological information, confirmation of treatment progress, confirmation of next treatment steps, etc.) In addition, the first information transmission control unit 52a inputs the voice of the medical staff in the examination room via the voice input unit 6, thereby controlling the information transmitted from the medical staff (for example, a request for biological information of a patient, a request for medical treatment, etc.). progress reports, notifications about next treatment steps, etc.). Note that the first information transmission control unit 52a may realize a videophone conversation via a virtual character between the medical staff outside the examination room and the medical staff inside the examination room.

Note that the first information transmission control section 52a displays a virtual character on the display section 5 instead of the non-contact input section 15 (information transmission section) and/or together with the non-contact input section 15 (information transmission section). One-way or two-way information transmission may be performed through virtual characters. Which component the virtual character is displayed on is controlled by, for example, the character moving unit 54.

The second information transmission control unit 52b shown in FIG. 5 performs one-way or two-way information transmission without using a virtual character. Note that the second information transfer control section 52b may be configured as a part of the function of the first information transfer control section 52a. The second information transmission control unit 52b allows medical staff outside the examination room or artificial intelligence (AI) to speak to the patient, the patient's attendant, or the medical staff inside the examination room using only voice without using a virtual character, for example. Encourage dialogue. The second information transmission control unit 52b acquires information (for example, greetings, responses in dialogue, etc.) transmitted from the patient, the attendant, and the medical staff in the examination room.

The information transmission control unit 52 controls one-way or two-way information transmission to patients and attendants based on information stored in the databases 43 and 46 (for example, recorded information recorded in the past by medical staff). You may go.
Further, the information transmission control unit 52 may perform one-way or two-way information transmission to the patient and attendant based on information collected and recorded in real time by videophone or the like.
Further, the information transmission control unit 52 may perform one-way or two-way information transmission to the patient based on interest information obtained from the patient. Interest information is information in which the patient has shown interest, and is specified based on, for example, the results of a questionnaire answered by the patient in advance.

Furthermore, the information transmitted to the patient, attendant, and medical staff in the examination room by the information transmission control unit 52 is information generated based on the patient's past or present information (including raw data extracted from the patient). It's good. The patient's past information includes medical record information. The patient's current information includes biological information such as body temperature, blood pressure, heart rate, and blood oxygen saturation. The patient's biometric information is obtained, for example, from a wearable device worn by the patient.

The character creation unit 53 has a function that can create a virtual character according to the preferences of the patient, attendant, or medical staff (dentist, dental hygienist, assistant, etc.). For example, the medical staff uses the character creation section 53 to create a virtual character suitable for the patient in advance. Note that the character creation unit 53 may automatically create a virtual character suitable for the patient based on information acquired from the patient. Furthermore, the medical staff may use the character creation unit 53 to create virtual characters associated with each medical staff member of the hospital. For example, avatars corresponding to medical staff may be created. As a result, when medical staff communicate information one-way or two-way via the virtual character, the provider who is transmitting the information can be easily recognized, so that the information can be transmitted more smoothly.

The character moving section 54 performs control to display the virtual character as if it were moving between the non-contact input section 15 and the display section 5. The non-contact input unit 15 and the display unit 5 are examples of a “first display unit” and a “second display unit”.
For example, the character moving unit 54 determines the location where the virtual character is to be displayed based on the situation of the patient's voice and dialogue, instructions from the medical staff, the medical treatment situation, the patient's situation, etc. The main control unit 51 and information transmission control unit 52 are notified. For example, the character moving unit 54 changes the location where the virtual character is displayed from the non-contact input unit 15 to the display unit 5 using a predetermined response from the patient as a trigger. Further, for example, the character moving unit 54 changes the location where the virtual character is displayed from the non-contact input unit 15 to the display unit 5, using the completion of a series of explanations to the patient as a trigger. Further, for example, by sensing the patient's interest in the content to be explained and instructing the clinical staff to move, the character moving unit 54 changes the location where the virtual character is displayed from the non-contact input unit 15 to the display unit 5. . Further, for example, when the medical staff instructs the virtual character to move after the end of treatment or counseling, the character moving unit 54 changes the location where the virtual character is displayed from the non-contact input unit 15 to the display unit 5.

FIGS. 10A and 10B show images when the location where the virtual character is displayed is changed from the non-contact input section 15 to the display section 5. As shown in FIGS. 10A and 10B, after the virtual character 71 is expressed to jump out of the screen on the character screen 70 displayed by the non-contact input unit 15, the virtual character 71 is displayed on the character screen 70 displayed by the display unit 5. It is expressed as if the character 71 had jumped into the screen.
For example, by understanding the positional relationship between the character screen 70 displayed by the non-contact input unit 15 and the display unit 5, the virtual character 71 can be expressed as if it has jumped into the display unit 5, or the direction in which it is jumping out can be expressed. The change in size may be set manually or automatically. In the case of manual operation, the settings are made in advance by key input, etc., based on the positional relationship between the two when installing this system. In the case of automatic setting, analysis is performed using a position detection sensor such as GPS that can automatically grasp each positional relationship, or a camera that can grasp the positional relationship between the two from a bird's-eye view.
As shown in FIGS. 1 and 2, in the positional relationship in which the display unit 5 is arranged at the front upper left of the non-contact input unit 15, the virtual character 71 is displayed on the character screen of the non-contact input unit 15, as shown in FIG. 10B. The virtual character 71 moves vertically from the lower right to the upper left of the screen and then pops out upwards, and then the virtual character 71 pops out from the bottom center of the screen of the display section 5 and then moves to the center of the screen. You can also express it as if you jumped into 5. In this way, it is preferable that the trajectory in which the virtual character 71 appears is expressed so as to seamlessly connect from the character screen 70 to the display unit 5. Further, for example, the character 71 may be moved from the display section 5 to the character screen 70 (return) after the information transmission to the patient is completed.
The display unit 5 is easier to increase in size than the non-contact input unit 15, and the image is clearer, so by displaying the virtual character 71 on the display unit 5, more detailed information can be transmitted to the patient. There is an advantage. In addition, since the display section 5 is arranged at the line of sight of the patient sitting on the patient chair 2, there is an advantage that the transmitted information is more likely to leave an impression on the patient because the display section 5 can more easily enter the patient's field of view. On the other hand, as described above, the non-contact input unit 15 allows input operations to be performed, so it has the advantage of facilitating two-way information transmission. In this way, the virtual character 71 is displayed at a location where it is easier to communicate information with the patient, taking into consideration the differences in characteristics between the non-contact input unit 15 and the display unit 5 and the type of information to be communicated. It is better.
