Description

[Technical field]

[0001] The present invention relates to a life assistance system. [Background technology]

[0002] Patent Document 1 discloses a technology in which an electric shaver is equipped with a camera for photographing the state of beard hair, and the image taken by the camera is sent to a processing terminal such as a smartphone that performs a process to determine whether or not there is any hair that has not been shaved, and the result is notified by voice or other means.

[0003] Furthermore, Patent Document 2 discloses a technology in which a camera is attached to a toothbrush to photograph the inside of the oral cavity, and the images captured by the camera are transmitted to a display such as a smartphone, allowing the user to brush their teeth thoroughly while visually checking the image of the inside of the oral cavity displayed on the display.

[0004] Patent Document 3 also discloses a technology in which the results (health and illness information) of an analysis using signals from biosensors (urine testing equipment, blood pressure and heart rate sensor, weight and tissue composition scale) installed in the home are displayed on a mirror display device that allows the user to simultaneously see an image displayed on a screen and a mirror image of the user reflected by the mirror surface, thereby projecting health and illness information in the mirror that reflects the user's image, allowing the user to naturally obtain health and illness information when looking at their own mirror image.

[0005] [Patent Document 1] Patent No. 6444152 [Patent Document 2] Utility Model Registration No. 3203253 [Patent Document 3] JP 2018-42812 A Summary of the Invention [Problem to be solved by the invention]

[0006] According to the technologies of Patent Documents 1 and 2, it is possible to reduce missed spots when shaving or brushing by photographing areas that are difficult to see even when using a mirror with a camera to make them easier to see, but this is troublesome in that a separate processing terminal and display must be prepared.Furthermore, when using a separately prepared processing terminal or display, since only the processing terminal or display is visible, it is not possible to completely eliminate missed spots when shaving or brushing, just as it is not possible to eliminate missed spots when shaving while enlarging your beard with a magnifying glass and checking the enlarged image (as you cannot see the whole picture).

[0007] In other words, shaving and brushing one's teeth are usually done in front of a mirror at a bathroom sink, but using a separate processing terminal or display in conjunction with a mirror is troublesome (it requires an extra step in addition to the everyday grooming tasks that have been performed habitually up until now), and so it has not yet become widespread.

[0008] Furthermore, the technology of Patent Document 3 requires the installation of biosensors in various places in the house in addition to the display device having a mirror surface, which makes it difficult to use.

[0009] The present invention aims to provide a life support system that is extremely easy to use and highly practical, by providing a display function to the mirror part of a washbasin, for example, which is used daily when caring for or beautifying the face or oral cavity, and by providing a camera in a treatment tool such as a razor or toothbrush, and by superimposing a captured image on the mirror part of the user, an image of the user's facial hair or the inside of the oral cavity can be displayed. This allows a user to view their own mirror image and enlarged images of their facial hair or the inside of their oral cavity with the minimum necessary eye movement, without significantly changing their current habits.

[0010] Another object of the present invention is to provide a user-friendly life support system that can automatically perform simple health checks during everyday life without the need to install biosensors in various places in the home. [Means for solving the problem]

[0034] A preferred embodiment of the present invention will be briefly described below with reference to the drawings to illustrate the operation of the present invention.

[0035] For example, when using the mirror surface of the mirror-type display device 2 provided on a washstand 1 used daily, when caring for the face or oral cavity (shaving, brushing teeth, etc.) or beautifying (applying makeup, etc.), a close-up image of the treatment area (cheeks or chin) including the beard, which is the treatment target, can be superimposed on the mirror image of the user and enlarged and displayed without a separate treatment terminal or display, and the close-up image is explicitly displayed on the mirror image of the user by AR (augmented reality), so the user can clearly see the treatment target while grasping the position and how to apply the treatment head of the treatment tool 3 (the user can see the close-up image with the minimum necessary eye movement while viewing the mirror image of the user), and therefore, it is possible to eliminate areas that are left unshaved or unbrushed as much as possible. Therefore, the care and beautification can be performed more easily and efficiently while feeling the same as in the past lifestyle habits.

[0036] In addition, in the invention described in claim 14, the health condition of the user who uses the washstand 1 is analyzed using an image of the face, and the analysis result is displayed on the mirror surface, so that a simple health check can be automatically performed by simply standing in front of the washstand 1 every day. Also, for example, if a health abnormality is detected, a message can be automatically sent to a medical institution or relatives, making it possible to check the safety of the user on a daily basis. EXAMPLES

[0037] A specific embodiment of the present invention will now be described with reference to the drawings.

[0038] This embodiment is a life support system comprising a washbasin 2 equipped with a mirror-type display device 1 having a mirror surface and a display unit capable of displaying an image so as to be superimposed on the mirror image reflected in the mirror surface, a treatment tool 3 for grooming or beautifying the user's face, including hair, or oral cavity, and a control unit.

[0039] Specifically, the processing tool 3 has a processing head unit for performing the maintenance or beautification, and a camera unit for taking close-up images including the processing object to be processed by the processing head unit. The processing tool 3 also has an illumination unit for taking good images. The processing tool 3 also has a transmission unit for transmitting the close-up images taken by the camera unit to a control unit (each processing tool 3 and the control unit are connected via a network).

[0040] The control unit is also configured to acquire the close-up image captured by the camera unit and display it on the display unit so as to superimpose it on the mirror image of the user reflected on the mirror surface.

[0041] Each part will now be described in detail.

[0042] Fig. 1 is a schematic explanatory diagram of the configuration of this embodiment, and Fig. 2 is a schematic explanatory perspective view of the washstand. In the drawings, symbol M is a mirror image of a user, and symbol A is a close-up image display area.

[0043] The washstand 1 (vanity unit) has a mirror section at the top that can reflect at least a part of the upper body including the face as a mirror-type display device 2, and the faucet, bowl, storage section, etc. at the bottom can be of the same configuration as a known washstand. For example, a commercially available washstand with the mirror section replaced with the mirror-type display device 2 can be used.

[0044] The mirror-type display device 2 can be a display with a known mirror function, such as a half-mirror type display in which a display unit is provided on the rear side of the reflective surface of a transparent half mirror, allowing the user to simultaneously view his or her own mirror image reflected in the half mirror and the image of the display unit passing through the half mirror.

[0045] This display is a touch panel, and can be operated in the same way as a smartphone or tablet to turn the close-up image display on and off, change the display area of ​​the close-up image, etc. The washstand 1 (mirror display device 2) may be provided with a camera and microphone for photographing the user, and configured as a smart display in which the display can be operated by gestures or voice from a control unit.

[0046] A toothbrush with a camera, a shaver with a camera (electric shaver), an earpick with a camera, a nose hair trimmer with a camera, a hair and makeup tool with a camera, etc. can be used as the treatment tool 3. In this embodiment, examples using a toothbrush and a shaver will be described in particular.

[0047] The control unit can be configured, for example, by a computer having a processor, memory, storage, a transmission / reception unit, I / O, etc.

[0048] In this embodiment, the control unit is provided in the washstand 1 (behind the mirror-type display device 2). The control unit acquires the close-up images transmitted from each processing tool 3, and controls the display unit to appropriately display the close-up images in the close-up image display area A of the mirror-type display device 2.

[0049] In this embodiment, the control unit is configured to perform visibility improvement processing to increase the visibility of the object to be processed in the close-up image captured by the camera unit while appropriately using a lighting unit, and to display the close-up image after the visibility improvement processing on the display unit.

[0050] An example of superimposing a close-up image on a mirror image M of a user shaving with a razor is shown in Fig. 3. In this embodiment, the close-up image display area A is a vertically elongated ellipse, but it can be set appropriately to a rectangular shape, a horizontally elongated ellipse, or other shape. The area, position, magnification, etc. of the close-up image display area A can also be set appropriately. It is preferable that the close-up image display area A be displayed below the face of the mirror image M of the user.

[0051] In the case of a shaver, the control unit performs a process of enlarging the close-up image and a process of left-right inverting (mirroring) the close-up image. Note that the control unit may also perform a process of up-down inverting or rotating the close-up image as necessary.

[0052] The control unit detects whiskers as processing objects in the close-up image and performs processing to highlight the whiskers. Specifically, for example, the control unit divides the close-up image into units (cells) of a certain size, and determines whether or not a whisker is present for each cell (for example, determining that a whisker is present when black, brown, or white is included), and performs processing to fill the cell determined to contain the whisker with a color that is recognizable as a whisker.

[0053] By explicitly displaying the location of the facial hair, the facial hair that needs to be shaved can be identified with certainty, and as many areas as possible can be left unshaved.

[0054] FIG. 4 shows an example in which a close-up image is superimposed on a mirror image M of a user brushing his / her teeth with a toothbrush.

[0055] In the case of a toothbrush, the control unit performs a process of enlarging the close-up image, a process of flipping the close-up image from side to side, and a process of detecting plaque and inflamed areas of the gums and teeth as the processing target in the close-up image and highlighting the plaque and inflamed areas of the gums. Note that the close-up image may also be flipped upside down or rotated as necessary.

[0056] By clearly displaying areas of plaque and inflamed gums, users can easily understand which areas they need to focus on brushing, and can also eliminate any areas left unbrushed as much as possible.

[0057] Specifically, the highlighted display of plaque and inflamed areas of the gums (areas of gums with periodontal disease) is performed using, for example, the algorithm shown in Fig. 5. Fig. 6 shows an image of the teeth and gums before the highlighted display, and Fig. 7 shows an image of the teeth and gums after the highlighted display.

[0058] Each step (S) in FIG. 5 will be described. S51: After acquiring the close-up image, image analysis is started. S52: The proximity image is divided into units (cells) of a certain size. S53: A cell to be analyzed is selected. S54: The attributes (color, brightness, etc.) of the data in the selected cell are compared with the attributes of sample data measured in the past. S55: If it is determined that the attributes of the data of the selected cell are similar to the attributes of the data of normal teeth, proceed to S61. S56: If it is determined that the attributes of the data in the selected cell are similar to the attributes of the data of normal gums (gingiva), the process proceeds to S61. S57: If it is determined that the attributes of the data in the selected cell are similar to the attributes of the plaque data, the cell is filled in a color that is recognizable as plaque (S58), and the process proceeds to S61. S59: If it is determined that the attributes of the data in the selected cell are similar to the attributes of data for periodontal disease (inflamed gums), the cell is filled in a color that indicates periodontal disease (S60), and the process proceeds to S61. S61: It is determined whether the comparison of the attributes of all the cells has been completed. If there are any remaining cells, the process returns to S53 and is repeated until the comparison of the attributes of all the cells has been completed. S62: End image analysis.

[0059] By highlighting important parts in the close-up image as described above, it is possible to display them clearly and in an extremely easy-to-understand manner to the user, allowing them to shave and brush their teeth efficiently and minimizing missed areas such as areas not being shaved or brushed.

[0060] In this embodiment, an example is described in which a shaver and a toothbrush are used as the treatment tool 3, but the same applies to other treatment tools 3. For example, in the case of an earpick, earwax is highlighted, and in the case of a nose hair trimmer, nose hair is highlighted, allowing for efficient care.

[0061] Also, when using a toothbrush, the control unit may be configured to analyze close-up images to determine whether there are any health abnormalities in the oral cavity, and if there are any abnormalities, to notify a medical institution (the user's dentist) or the user's relatives of the abnormality or to automatically make a medical appointment (similarly, a shaving tool may be configured to notify or make an appointment with a dermatologist, and a nose hair trimmer / ear pick may be configured to notify or make an appointment with an otolaryngologist). Also, if there are any abnormalities, a message recommending a visit to a hospital or a dental checkup may be displayed on the mirror, or a message urging the user to be careful (such as stress building up, or a higher or lower level of XX than usual) may be displayed, or promotional information such as information on recommended medicines or health foods may be displayed.

[0062] Since this embodiment is configured as described above, when the mirror surface of the mirror-type display device 2 provided on the washstand 1 used daily is used to care for and beautify the face and oral cavity, a close-up image of the treatment area (cheeks and chin) including whiskers, which is the treatment object, can be superimposed on the mirror image of the user and enlarged and displayed without the need for a separate treatment terminal or display, and the close-up image is explicitly displayed on the mirror image of the user by AR (augmented reality), so the user can clearly see the treatment object while grasping the position and how to apply the treatment head of the treatment tool 3 (the close-up image can be seen with the minimum necessary line of sight movement while seeing the mirror image of the user), and therefore, it is possible to eliminate areas left unshaved or unbrushed as much as possible. Therefore, the care and beautification can be performed more easily and efficiently while feeling the same as in the past lifestyle habits.

[0063] Therefore, this embodiment is a life assistance system that is extremely easy to use and highly practical. EXAMPLES

[0064] The second embodiment is an example in which a washstand 2 equipped with a mirror-type display device 1 similar to that of the first embodiment is used to monitor daily health conditions.

[0065] Specifically, the life support system includes the washstand 2 equipped with the above-mentioned mirror-type display device 1, a camera unit, and a control unit.

[0066] The camera unit of this embodiment is provided at a position where it can capture the user's face reflected in the mirror surface of the mirror-type display device 1, and the control unit measures vital signs such as pulse wave, heart rate, SpO2 (oxygen saturation), pupil size, or face color from the image (video) of the face captured by the camera unit, analyzes the health condition by comparing the measured values ​​with values ​​in a database of the user's past measurement results (AI may be used), and displays the analysis results by superimposing them on the mirror image of the user reflected in the mirror surface by the display unit. In this embodiment, the brightness value change of the image is analyzed to measure the value of each vital sign.

[0067] The measurement result database accumulates the values ​​of each vital sign for each individual on each measurement date.

[0068] Specifically, the analysis of the health condition from the image of the face is performed using, for example, the algorithm shown in FIG.

[0069] Each step (S) in FIG. 8 will be described. S81: Start analysis. S82: An image of a face is obtained. S83: Identifying individuals from facial features. S84: By analyzing the change in the brightness value of the image, the pulse wave, heart rate, SpO2, pupil size, facial color, etc. are measured. S85: The measured information is recorded for each individual in a database (S86) and is also displayed on the mirror surface. S87: The current vital sign information (S84) is compared with the information in the database (S86), and the health information is analyzed and displayed. S88: End the analysis.

[0070] In addition, the control unit may be configured to perform analysis based on the results of comparing the values ​​measured by a sensor of a toothbrush having a sensor capable of measuring pulse waves, heart rate, or SpO2 with the values ​​in the database of past measurement results, in addition to the values ​​measured from an image of the face.

[0071] The analysis in this case can be performed, for example, using the algorithm shown in FIG.

[0072] Each step (S) in FIG. 9 will be described. S91 to S93 are the same as S81 to S83 in Fig. 8. Moreover, S95 to S97 are the same as S85 to S87 in Fig. 8. S94: By analyzing the brightness value change of the image and the information acquired by the toothbrush sensor (S98), the pulse wave, heart rate, SpO2, pupil size, facial color, etc. For example, for vital signs that can be acquired by the toothbrush sensor, the values ​​acquired by the toothbrush are used. S99: End analysis.

[0073] The washstand is also provided with a speaker and a microphone, and the control unit is configured to acquire the user's voice response to the call, analyze the acquired voice response, and display the analysis result on the mirror unit. For example, mental illnesses such as depression can be detected and displayed by voice analysis.

[0074] Furthermore, the control unit is configured to notify a medical institution (family doctor) or the user's relatives of a message to that effect, or to automatically schedule a medical appointment, if the analysis results indicate a health abnormality. If an abnormality is indicated, the control unit may display a message on the mirror surface encouraging the user to visit a hospital or a dental checkup, display findings or messages calling the user's attention (such as stress buildup, or high or low XX compared to normal), or display promotional information such as information on recommended medicines or health foods.

[0075] Moreover, the configuration of the second embodiment may be added to the configuration of the first embodiment.

[0076] Since this embodiment is configured as described above, the health condition of the user using the washbasin 1 is analyzed using an image of the face, and the analysis results are displayed on the mirror surface, making it possible to automatically perform a simple health check by simply standing in front of the washbasin 1 every day.

[0077] In addition, if any health abnormalities are detected, messages can be automatically sent to medical institutions and relatives, making it possible to check on the safety of the person on a daily basis.

[0078] Therefore, this embodiment provides a user-friendly life support system that can automatically perform simple health checks in the course of everyday life.
