Description

  The present invention relates to a navigation system attached to glasses or sunglasses for protecting from light harmful to eyes such as vision correction and ultraviolet rays, goggles for protecting eyes from invasion of pollen or dust.

  Conventionally, a navigation system has been invented that allows a user to arrive at a destination reliably and quickly by installing (installing) it in an automobile or the like and guiding the route (guidance) to the destination. It has been put to practical use.

  In recent years, it has also become possible for pedestrians to provide walking directions to their destinations using information terminals such as smart phones having a mobile phone function and portable information terminals such as tablet terminals. Yes.

  In Patent Document 1, a smart phone is used as a navigation system by reading a barcode of a book or pamphlet for sightseeing spots using a smart phone, etc., and public facilities, sightseeing spots, sights, historic sites, accommodations, restaurants It has been proposed to give directions to facilities such as gas stations.

JP 2013-108777 A

  However, in the conventional navigation system, even if a pedestrian operates a portable information terminal and displays a map in an unknown land, the location and moving direction of this map and his / her current location are not accurately known. There is a problem that it is not accurately known from the position information received by the GPS which one should walk. For this reason, it is necessary for the user to check the screen of the information terminal while walking, and to predict the current current position and moving direction from the change in the position information received by GPS to determine its own moving direction. I noticed that the current direction of travel was wrong.

  In such a case, the user may stop while looking at the screen of the portable information terminal or may suddenly change direction, which may cause an accident such as a collision with the surrounding people. For this reason, attention has been drawn to improving manners when using information terminals. Many elderly people are afraid of reaching such a situation and do not have a portable information terminal, and there is a situation in which they cannot take advantage of advances in information technology.

  Furthermore, in the navigation system currently used for the portable information terminal, there is a navigation system that searches for and guides the shortest distance route from the current position to the destination and several detour routes associated therewith. Because there is no route search because there is no way to select a route that is easy to pass for people with limited mobility (for example, a pedestrian bridge with a pedestrian crossing or an elevator instead of a pedestrian bridge with stairs). In some cases, it was possible to get stuck on the road, search again for another route, and make a detour, or in the worst case, no route could be used to reach the destination. In the first place, it cannot be used for people with disabilities who cannot see the screen of the information terminal, and it is not useful for the elderly and the physically disabled.

  The present invention has been made in consideration of the above-mentioned matters, and can be used when any user moves on foot or in a wheelchair, and provides route guidance to a destination while ensuring safety during movement. It is an object to provide a wearable navigation system capable of performing the above.

In order to solve the above-mentioned problem, the first invention is that the user can visually check in a visual aid that is attached to the user's head and mainly assists the eyes, and presently guides not only the user but also the surroundings. A display unit showing a moving direction in the display, and the display unit is provided on the right and left light transmitting parts of the glasses as the visual aid, and a semi-transparent monitor that can be visually confirmed by the user, and notification to surrounding people by light The light emitters are provided on the left and right side surfaces of the frame of the glasses, and the destination setting means for setting the destination and the measured value of the gyro sensor. a current position input means for inputting position information on the current location becomes the position information receiving unit that performs compensation using, Lou to find the movement route from the current position sequentially inputted by the current position input means to said set destination Mounting comprising: search means; and display processing means for displaying a moving direction indicating which direction the user should move from the direction visually confirmed by the user according to the searched route. A type navigation system is provided (claim 1).

  According to the wearable navigation system of the present invention, the user sets the destination using the destination setting means and attaches the visual aid to the head so that the current position input means can detect the position of the user's current location. Information is input, the route search means searches for a moving route from the current location to the destination, and the display processing unit displays the moving direction on the display unit according to the searched route. Therefore, the user confirms the moving direction displayed on the display unit of the visual aid together with the surrounding safety, and when moving in this moving direction, either can arrive at the destination.

  The visual aid includes glasses, sunglasses, goggles, and a wearable terminal that are attached to the user's head and have an auxiliary function such as protection and visual correction for the user's eyes, and the display unit It is possible to display the moving direction during walking that the user can visually check. The display unit is preferably a small monitor that uses an optical element to display a translucent image in front of the user, but the left and right positions are such that the user can check the lighting state with the visual aid on. It may be a light emitting diode provided in the above. Further, the display unit may indicate not only the user but also the moving direction being currently guided by, for example, an orange light emitting diode, like a direction indicator with respect to the surroundings. In this case, since the user's direction of movement can be indicated to surrounding people, it is possible to prevent the occurrence of a collision or the like due to a sudden change of direction.

  The destination setting means includes a voice input unit such as a microphone for inputting by the user's voice, a voice recognition program for converting the inputted voice information into character information, and a list for creating a destination list using the voice-recognized information. It is conceivable to include a creation program and a destination selection unit such as an input key for selecting a destination from the list. However, even if an input unit such as a keyboard for short-distance communication is provided, a code for specifying coordinate information or position information indicating a destination is input and set by communication from another information terminal. Also good.

  The current location input means is at least an artificial GPS (Global Positioning System operated by the United States, and may be a system for transmitting position information such as GLONASS, Galileo, North Capital, IRNSS, etc.). It can be a location information receiving unit that can input information such as coordinate information and moving direction of the current location through communication with satellite and IMES (Indoor Positioning System) terminals. The accuracy is improved by complementing the position information. That is, it can be considered that the correction is performed with higher accuracy than the amount of change in the position information using the gyro sensor and the change in the image captured using the camera.

  The route search means searches for a travel route to the destination using map information for pedestrians that records a travel route including at least a route in a building that is accessible by walking. It is conceivable that a user can select a plurality of routes such as a route, a route with little fluctuation in the vertical direction, and a route selected for ease of walking including a road width by using a display unit or the like.

  The destination setting means, the current position input means, the route search means, and the display processing means can be realized by a program executed by an arithmetic processing unit provided in the visual aid. However, at least one of destination setting means, current location input means, route search means, and display processing means is realized by a program executed by the arithmetic processing unit of the mobile terminal connected to the visual aid by short-range wireless communication. You may be made to do.

  In the wearable navigation system having the above-described configuration, the moving direction is indicated to the user via the display unit, and thus the user can check the traveling direction without staring at the mobile terminal during walking. Here, it is conceivable that the position information input from the current location input means includes some errors, especially when starting up, the exact current location is not clear, and the direction of movement displayed on the display unit is also indicated. Although it may be unstable, since the current location can be determined gradually as the user moves, the display on the display unit gradually becomes stable. Here, the user does not stop and stare at the screen of the mobile terminal as in the past, and the direction is not changed without confirming the traveling direction, so that safety is improved.

  Pedestrian map information having route information including at least one of steps, slopes, sidewalk widths, presence / absence of visually impaired person guidance blocks on the route, and permission as user characteristics In the case of searching for a travel route using user characteristic information including at least one of a step, the size of a wheelchair or a walking aid, and presence / absence of visual impairment (claim 2), the user Since the route search according to the characteristics of can be performed, the searched route does not become inaccessible to the user, which is useful.

  For example, when a user of a wheelchair including a senior car is set as the user characteristic information or when using a wheelbarrow as a walking assist device, the route search means has a step and has a slope. Only the route that is wider than the width of the wheelchair or walking aid including the senior car is selectively searched. Similarly, when a visually impaired person is set as the user characteristic information, the route search means preferentially searches for a route having a visually impaired person guidance block.

  The pedestrian map information includes route information that includes at least one of steps, slopes, sidewalk widths, and presence / absence of blocks for guiding the visually impaired. Pedestrians can pass according to the conditions of the users. It is preferable that every route that can be used on foot is recorded. In addition, the pedestrian in the present invention is used as a general term for a user who moves at a low speed using a simple assisting device as much as possible. It is an expression that includes the case of moving at a low speed with the help of a senior car or a wheelchair to assist in the functional decline of the car.

  The pedestrian map information and user characteristic information are recorded in a storage unit of a mobile terminal connected to the visual aid by short-range communication, and the destination setting means, current location input means, route search means, display processing When the means is realized by executing software executed by the arithmetic processing unit of the mobile terminal (Claim 3), the configuration of the visual aid can be simplified. The weight of the vessel can be reduced. In addition, since the information processing capability of mobile terminals has improved dramatically, it has a storage unit that can sufficiently store pedestrian map information and user characteristic information, and can set destinations, input location information, Information processing relating to route search and generation of guidance display contents can be performed sufficiently quickly.

  The mobile terminal includes a mobile phone type information processing terminal (so-called smart phone), a tablet type information processing terminal (so-called tablet PC), and a mobile PC including a notebook type. The wireless communication using electromagnetic waves is preferable because the degree of freedom is increased, but short-distance communication realized by connection using a communication cable may be used.

  The pedestrian map information is recorded in a recording unit of a wearable navigation service providing server on the Internet, and the destination setting means, current location input means, route search means, and display processing means are connected to the visual aid by short-range communication. In the case of being realized by execution of software executed by an arithmetic processing unit of a mobile terminal connected and connected to the Internet by wireless communication (Claim 4), the configuration of the visual aid is simplified. Therefore, the weight can be reduced accordingly.

  Since the pedestrian map information is recorded in the recording unit of the wearable navigation service providing server, the user is always up-to-date by updating the pedestrian map information regularly to keep it up to date.

  2-7 is a figure which shows an example of the content displayed on the display parts 5A and 5B in the example in which a walking difficult person moves by walking using the wearable navigation system 1 of the said structure. The pedestrian map information 28 and user characteristic information 29 are recorded in advance by connecting to an information terminal such as a personal computer before using the wearable navigation system 1.

  As shown in FIG. 2, for example, when the user activates the destination setting program 20 by pressing the enter key 7B and inputs it by voice, for example, “Odaiba”, the destination setting program 20 executes voice recognition. In addition, the display unit 5A (5B) includes a list of locations that can be set as destinations from “Odaiba” determined by voice recognition, a command input unit for returning to the previous step, and a cancel command input unit. The cursor C is displayed, and the cursor C can be moved using the selection key 7A and can be input using the enter key 7B.

Find the route to the destination. At this time, the route search program 21 is recorded as pedestrian map information 28, such as recorded step information on the route, slope, road width, presence / absence of blocks for guiding the visually impaired, and user characteristic information 29. The route is selected according to information such as the allowable level difference, the size of the wheelchair or walking aid, the presence or absence of visual impairment, etc., and there are several features such as the shortest route, the minimum vertical movement route, the width priority route etc. Search for a route.

  As shown in FIG. 3, several routes searched are displayed as a list on the display unit 5A (5B). In addition to the command input unit for returning to the previous screen and the cancel command input unit, Since the cursor C is displayed, the user can select a route using the cursor C. Here, the user can select one route. Note that all the routes listed in this list are searched using the user characteristic information 29 and the pedestrian map information 28, and therefore, the optimum route according to the characteristics of the user is selected. .

  FIG. 4 shows an example of a screen displayed on the display unit 5A (5B) when one route is selected from the list. The display unit 5A (5E) displays map information M around the current location H. Then, the route information R composed of arrows displayed on the map information M is displayed.

  As shown in this example, the entire route R is placed to the extent that the user can check visually, so the map M indicates which direction the user should proceed from the current location to go to the destination. Since it can be confirmed by the route information R displayed in an overlapping manner, it can be determined to some extent whether or not the selected route is easy for the user to move. When the user can confirm the route information R, the user can guide the road from the current location by moving the cursor C to start guidance and making a decision.

  FIG. 5 is a diagram illustrating an example in which route guidance is performed using a wearable navigation system. As shown in FIG. 5, when the user starts guidance, the display processing program 22 of the wearable navigation system needs to change the arrow V indicating the latest moving direction to the display unit 5A (5B) and the distance that the traveling direction needs to be changed. Is displayed by the character T1. In the case of this example, the guidance is to go to the left after 5 m.

  If the arrow displayed on the screen 5A (5B) is displayed in the forward (straight) direction, the user walks in the forward direction, and the display of the arrow V is displayed in the backward (reverse) direction. For example, if you walk backward, you can start walking in the correct direction to the destination. When the display processing program 22 displays the guidance arrow V in the traveling direction, it is preferable that the next guidance is displayed also to those around by using the light emitters 6A and 6B. As a result, people in the vicinity can predict the movement of the user in advance, so that the occurrence of a contact accident can be prevented.

  The position information input by the GPS receiver 8 may include some errors especially at the time of start-up, but by correcting using the measured value of the gyro sensor or the image data input from the camera 9, the arrow information The guidance by V can be stabilized.

  Further, the display processing program 22 uses the camera 9 to confirm an image that the user will visually confirm and confirms in which direction the user should move from the direction that the user visually confirms using the arrow V. Since the display and guidance by the letter T1 are also provided, the user does not stop or stare at the information terminal to confirm where his current location is on the map as in the past. It is only necessary to move while confirming the safety of the surroundings according to the guidance displayed on the display unit 5A (5B).

  In addition, the safety confirmation program 23 analyzes the image captured by the camera 9 to confirm that there is a step at a position 2 m ahead of the user, and detects this as danger information. Therefore, the display processing program 22 blinks a warning mark A for calling attention and a character T2 such as “2 m ahead step” at a position where the step can be visually confirmed, and simultaneously uses the bone conduction speaker 10C to inform the user. For example, “Please note that there is a step of about 5 cm at 2 meters ahead”. In addition, since this voice guidance serves as a display for visually impaired persons to confirm the surrounding danger, it is expressed as a display in this specification. In addition, voice alerts may be performed using the speakers 10A and 10B that can be heard externally.

  Since the safety confirmation program 23 displays an alert, the user can quickly notice a situation requiring attention in the traveling direction, which contributes to an improvement in safety. Further, since most of the display portions 5A and 5B do not display anything, the user can visually confirm the surrounding situation.

  FIG. 6 is a diagram showing the contents displayed when the user further moves to before the descending escalator. As shown in FIG. 6, when the user approaches the escalator, the display processing program 22 confirms the arrow V and the letter T3 “Descent at B1” as the next guidance, to get off the escalator on the first basement floor. Can definitely confirm and head to the destination. In addition, since the safety confirmation program 23 analyzes the image captured by the camera 9 and detects the step portion before the escalator, the danger notification program 24 causes the warning mark A to blink and display, for example, “1 m ahead step”. Therefore, the user can safely move while paying attention to the step just before entering the escalator.

  FIG. 7 is a diagram showing the contents displayed when the user further moves to the front of the intersection. As shown in FIG. 7, when there is a traffic signal in the direction of travel at the intersection, the safety confirmation program 23 confirms that the front signal is red, and the danger notification program 24 causes the warning mark A to flash and display. For example, a warning is given by the letter T5 such as “the signal is red”. Similarly, the safety confirmation program 23 confirms that the vehicle ahead is approaching the user, and the danger notification program 24 flashes the warning mark A and displays characters such as “car is coming”. Calls attention by T6. These alerts allow the user to cross the intersection more safely to the destination.

  Furthermore, when the user ignores the signal and tries to cross the intersection other than blue, the safety confirmation program 23 preferably gives a warning to the user by generating an alarm from the speakers 10A and 10B. Needless to say, this configuration is particularly useful for the visually impaired. Therefore, even when the user does not operate the visual aid 2 as the service providing system 1, the safety confirmation program 23 and the danger notification program 23 ignore the red light, approach dangerous places such as walls and steps, Furthermore, when a contact with a vehicle or other moving object is expected, such as when a notification about a moving object whose collision is predicted is received from the mutual position search server 4, the situation is always dangerous when a contact with an automobile or other moving objects is expected. It is preferable to call attention to the urgency.

  In addition, since it can be confirmed from the position information of Mr. A's current location received from the mutual position search server 4 that the friend A is on the third floor of the building diagonally left front, the display processing program 22 displays a warning mark A. While blinking, a character T7 such as “100mA 3F” is displayed to indicate the position of the friend. Accordingly, the user can immediately join the friend and go to the destination without moving wastefully to meet the friend.

  Next, health status monitoring by the service providing system 1 will be described. That is, the visual aid 2 of the present invention uses the biosensors 11A and 11B to measure a vital value consisting of at least one of a user's blood pressure, pulse rate, respiratory rate, and body temperature, and the health condition confirmation program 25 It has a function to constantly check the health status of users. In addition, the support request notification program 26 uses the speakers 10A, 10B and the like to generate “please help me” around the sound when the health condition confirmation program 25 confirms that the health condition has deteriorated. The notification program 27 can notify the surrounding people of support requests by causing the light emitters 6A and 6B to flash in red and emit light.

  Further, the abnormality notification program 27 simultaneously notifies the user abnormality notification server 4 of the location information of the user's current location and the measured vital value to the wireless communication units 13 and 14 and the Internet 3. On the other hand, the user abnormality notification server 4 transmits the abnormality notification received from each visual assistance device 2 to the information terminal 15 of the registrant recorded in advance in the abnormality notification database 4B by using e-mail, SNS message, or the like.

  In the example shown in FIG. 1, for example, a text message MT “Mr. XX is in poor health near XX. Current blood pressure is…” and a button MB for displaying a map of the current location are displayed and used. It is configured so that the person's saddle can be noticed quickly.

  It is preferable that the user can consciously request the rescue by, for example, pressing and holding the buttons 7A and 7B. In addition, even if you do not request rescue or notify you of an abnormality, when the measured vital value deviates from the standard vital value or fluctuation range obtained from the normal vital value of the user, The health condition confirmation program 25 detects this, and first notifies the user that the vital value is different from the normal state through the display on the display units 5A and 5B, the bone conduction speaker 10C, etc., and calls attention. Is preferred.

  As a result, the user's autonomic nerves decrease with age, so users can be aware of this when they are in a condition that can cause poor physical condition such as heat stroke, and they can take early measures before they become important. it can.
