Description

Technical Field

[0006]

[0001] The present disclosure relates to a display processing device that displays the position of a target person, etc.

Background Art

[0002] The position of the owner of a mobile terminal has been estimated using the function of GPS (Global Positioning System) provided in the mobile terminal. However, GPS measures the position using radio waves emitted by artificial satellites, and it is impossible to accurately estimate the position indoors or the like where radio waves from artificial satellites cannot reach.

[0003] Therefore, for example, information from a plurality of base stations that communicate with a mobile terminal is aggregated to identify the position of the mobile terminal. Further, Patent Document 1 describes a system for estimating the relative positional relationship between the owner and the wireless communication terminal based on the radio wave intensity in the wireless communication between the wireless communication terminal held by the holder and a plurality of wireless communication devices.

[0011] [Embodiment 1] An embodiment of this disclosure will be described in detail below. The display system 1 according to this embodiment identifies and displays the indoor location of a subject, even when the subject is inside a building, by having multiple wireless LAN (Local Area Network) access points installed within the building. Even when the subject is indoors, the system identifies and displays the location of the mobile device the subject is carrying, so the subject's location can be determined even when GPS location determination is difficult. The subject may be one person or multiple people. If there are multiple subjects, for example, in a company with multiple employees, an administrator can check the current location of each employee. In this embodiment, an example of installing wireless LAN access points indoors will be given, but it is possible to identify the subject's location as long as wireless LAN access points are installed. Therefore, the invention according to this disclosure is not limited to indoors but can also be applied outdoors.

[0012] Figure 1 shows an overview of the display system 1. FIG. 1 is a functional block diagram showing the main component configuration of the display system 1. As shown in FIG. 1, the display system 1 includes a display processing device 10, a display device (display unit) 20, and a mobile terminal 30.

[0013] The mobile terminal 30 is a mobile terminal possessed by the target person. Since the target person is the person who possesses the mobile terminal 30, the target person is also referred to as the possessor. The mobile terminal 30 performs wireless communication with one or more access points 50 installed indoors. The mobile terminal may be a so-called smartphone and has a wireless communication function, a GPS function, a telephone communication function, etc. Since these functions are possible using known technologies, specific descriptions are omitted. The access point 50 is a wireless LAN access point compliant with a standard such as Wi-Fi (registered trademark).

[0014] The display device 20 is a display device that displays information. The display device 20 may be included in the display processing device 10.

[0015] The display processing device 10 processes information to be displayed on the display device 20 and includes an acquisition unit 11, a position identification unit 12, a display processing unit 13, and a storage unit 14. The display processing device 10 and the mobile terminal 30 can communicate with each other via the Internet or the like.

[0016] The storage unit 14 stores terminal information 141, AP information 142, map information 143, and log information 144. FIG. 2 shows examples of the terminal information 141, AP information 142, and log information 144 stored in the storage unit 14. 201 in FIG. 2 shows an example of the terminal information 141. As shown in 201, the terminal information 141 is information in which a terminal ID for identifying the mobile terminal 30 and the person who owns the mobile terminal 30 are associated with each other. In the example shown in FIG. 2, the owner of the terminal ID "AAA" is "Person A", the owner of the terminal ID "BBB" is "Person B", and the owner of the terminal ID "CCC" is "Person C", and they are associated in this way. By using the terminal information 141, it is possible to identify the person who is the owner of the mobile terminal 30 corresponding to the information acquired by the display processing device 10.

[0017] 202 in FIG. 2 shows an example of the AP information 142. As shown in 202, the AP information 142 is information in which an APID for identifying the access point 50, the location where the access point 50 is arranged, and the location on the floor map (map) (map location) are associated with each other. In the example shown in FIG. 2, the access point 50 with the APID "W06001" is arranged at the "First Table", and the location on the floor map is "X1, Y1". The access point 50 with the APID "W06002" is arranged at the "Second Table", and the location on the floor map is "X2, Y2". The same applies hereinafter. The method for specifying the location on the floor map is an example and is not limited thereto. As long as the location of the access point 50 on the floor map can be specified, it may be specified in any format.

[0018] FIG. 3 shows an example in which the access points 50 are actually arranged on a certain floor. Here, an example in which 14 access points 50 from W060001 to W060014 are arranged on the floor is shown. For example, the map location in the AP information 142 indicates the arrangement location of the access point 50 on this floor.

[0019] Figure 2, section 203, shows an example of log information 144. Log information 144 is a history of radio wave information and GPS information acquired by the acquisition unit 11 from the mobile terminal 30. As shown in Figure 2, log information 144 stores the time of acquisition, the terminal ID identifying the transmitting mobile terminal 30, radio wave information, and GPS information in association with each other.

[0020] Figures 204 and 205 in Figure 2 show examples of displays on the display device 20, which will be described later. Figure 204 shows an example where the names, current locations, and location details of the subjects are displayed in a list. Figure 205 shows a list of people who were present at a specific time and place.

[0021] Map information 143 includes a floor map and area information. Area information identifies a designated area, which is a pre-specified area, using a polygon. Area information consists of the latitude and longitude of the points corresponding to each vertex of the polygon representing the designated area, and information indicating the line segments connecting each point. The area enclosed by the line segments connecting each point is the designated area indicated by the area information. The name of the designated area represented by the polygon is also associated with the area information. Furthermore, the area information may also include the latitude and longitude of the vertices of the polygon representing the building area, which is the area of ​​buildings within the designated area. There may be multiple building areas within the designated area.

[0022] Figure 4 shows examples of designated areas and building areas indicated by area information. Point 401 in Figure 4 represents the designated area AR1, a polygon formed by seven vertices from vertex V11 to vertex V17. Each vertex of designated area AR1 is located as follows: for example, vertex V11 is located at (latitude LA11, longitude LO11), and vertex V12 is located at (latitude LA12, longitude LO12). The same applies to vertices V13 and beyond.

[0023] Furthermore, 402 in Figure 4 shows the building area BR1 within the designated area AR1. The building area BR1 is indicated by four vertices, V21 to V24.

[0024] The acquisition unit 11 repeatedly acquires radio wave information, including radio wave intensity (the strength of the radio waves received by the mobile terminal 30 from each of the access points 50), and GPS information from the mobile terminal 30. The timing of the repetition may be periodic. The radio wave information includes the strength of the radio waves received from the access point 50 and identification information that identifies the access point 50. The GPS information includes location information of the mobile terminal 30 identified by GPS, such as information indicating latitude and longitude. GPS information does not necessarily have to be acquired, because the mobile terminal 30 may not be able to receive radio waves from satellites used in GPS.

[0025] The location identification unit 12 uses the radio wave information acquired by the acquisition unit 11 to identify the location of the subject, who is the owner of the mobile terminal 30. More specifically, the location identification unit 12 identifies the location of an access point 50 indoors where the radio wave strength included in the radio wave information exceeds a first threshold as the subject's location. The indoor locations of the access points 50 are stored in advance in the AP information 142 of the storage unit 14. If there are multiple access points 50 with radio wave strength exceeding the first threshold, the location identification unit 12 identifies the location of the access point 50 with the strongest radio wave strength as the subject's location. If there are no access points 50 with radio wave strength exceeding the first threshold, the location identification unit 12 identifies the subject's location based on GPS information. If there are no access points 50 with radio wave strength exceeding the first threshold, the subject is likely to be outdoors, and therefore, GPS information is likely to be acquired. If there are no access points 50 with a signal strength exceeding the first threshold, and GPS information has not been acquired, the location identification unit 12 will use the most recently acquired access point 50 with a signal strength exceeding the first threshold, or the GPS information, to determine the location of the subject. The unit will use whichever of the access points 50 or GPS information was acquired more recently.

[0026] As described above, the location identification unit 12 determines the location of the subject using the radio wave strength when the radio wave strength exceeds the first threshold, and determines the subject's location using GPS information when the radio wave strength is below the first threshold.

[0027] If there are multiple subjects, the system may include a selection reception unit (not shown) for selecting a subject whose location is to be determined, and the location determination unit 12 may determine the location of at least one of the selected subjects.

[0028] The display processing unit 13 displays the location of the person identified by the location identification unit 12 on the display device 20 on the floor map or on a map. Specifically, if there is an access point 50 whose radio wave strength exceeds the first threshold, the display processing unit 13 displays the location of the access point 50 on the floor map. The location of the access point 50 on the floor map is stored in the AP information 142 of the storage unit 14, and the floor map is stored in the map information 143 of the storage unit 14. In addition to displaying the location, the display processing unit 13 may also display the radio wave strength. Since radio wave strength can be said to indicate the distance from the access point 50, the greater the radio wave strength, the higher the probability that the person is closer to the access point 50. Therefore, by displaying the radio wave strength, it is possible to show how close the person is to the access point 50.

[0029] Furthermore, if there are no access points 50 whose radio wave strength exceeds the first threshold and GPS information is being acquired, the location identification unit 12 displays the location indicated by the GPS information on the map.

[0030] When determining the location of a subject based on GPS information, the location determination unit 12 determines whether the location indicated by the GPS information is within a designated area. If it is outside the designated area, the display processing unit 13 displays the location indicated by the GPS information directly on the map. On the other hand, if it is within the designated area, the display processing unit 13 displays the subject's location on the map along with the name of the designated area. Furthermore, if it is within a building area within the designated area, the display processing unit 13 displays the subject's location on the map along with the name of the building.

[0031] Furthermore, if there are multiple subjects, the display processing unit 13 displays their respective locations in a list. Figure 2, 204 shows an example of the list display. As shown in Figure 2, 204, the list display shows the subject's name, building and floor number, and location details in association. In the example shown in 204, there are seven subjects, from "Mr. A" to "Mr. G," and "Mr. A"'s current location is "Factory X, 2nd floor," with location details "X-00001," "Mr. B"'s current location is "Factory Y, 1st floor," with location details "Y-00003," and so on. "Building and floor number" indicates the building and floor where the subject is located. Clicking on "Location details" transitions to a screen displaying the location on a floor map. Also, "Mr. F"'s current location is "Not detected," which indicates that there are no access points 50 with radio wave strength exceeding the first threshold, and the location indicated by the GPS information is outside the designated area. In this case, clicking on the "Map" section in "Location Details" will take you to a screen showing F's location on a map. Also, G's current location is shown as "W Factory," which indicates that there are no access points 50 with signal strength exceeding the first threshold, and that the location indicated by the GPS information is within the designated area (W Factory). In other words, "W Factory" is the name of the designated area. In this case, clicking on the "Map" section in "Location Details" will take you to a screen showing G's location at W Factory on the map. Furthermore, for example, if the subject's location is within the building w1 factory area of ​​W Factory, the name of the designated area and the name of the building area may be displayed together, such as "W Factory - w1 Factory."

[0032] Figure 5 shows an example of the floor map displayed when clicking on "H-600011" in the location details for person D. Figure 5 shows that person D is near the location "W06006" of access point 50. In addition, the example shown in Figure 5 shows related information for person D, namely that D is currently "in a meeting" and that the meeting is scheduled from 13:00 to 14:00.

[0033] Thus, the display processing unit 13 may display the subject's location along with related information on the floor map. The related information may include, for example, the subject's status such as being busy, in a meeting, or on break, the meeting start time, end time, and planned departure time.

[0034] Figure 6 shows an example of the map displayed when you click "Map" in the location details for Person F. Figure 6 shows that Person F is located at point P2 on the map.

[0035] [Processing flow] Next, the processing flow in the display processing device 10 will be explained with reference to Figure 7. Figure 7 is a flowchart of the processing flow in the display processing device 10. As shown in Figure 7, the display processing device 10 repeatedly acquires radio wave information and GPS information from the mobile terminal 30 held by the target person (S101, acquisition step).

[0036] Next, the location identification unit 12 analyzes the radio wave strength included in the radio wave information (S102) and determines whether the radio wave strength exceeds a first threshold (S103). If the radio wave strength exceeds the first threshold (YES in S103), the location of the access point 50 corresponding to that radio wave strength is identified as the location of the mobile terminal 30, i.e., the location of the target person (S104, location identification step). If there are multiple radio waves with radio wave strengths exceeding the first threshold, the location of the access point 50 corresponding to the strongest radio wave strength is identified as the location of the target person.

[0037] On the other hand, if the radio wave intensity does not exceed the first threshold, the location identification unit 12 assumes the target is outdoors and uses GPS information to identify the location of the mobile terminal 30 as the target's location (S105). As described above, when using GPS information, the location identification unit 12 determines whether or not the target's location is within the designated area. The display processing unit 13 then displays the target's location identified by the location identification unit 12 on the display device 20 on the floor map or map (S106, display processing step). The above is the processing flow in the display processing device 10.

[0038] As described above, the display system 1 according to this embodiment includes a display processing device 10, a portable terminal 30 capable of communicating with the display processing device 10, and a display device 20. The portable terminal 30 is capable of communicating with multiple access points 50 of a wireless LAN installed indoors. The display processing device 10 causes the display device 20 to display the location of the portable terminal 30, in other words, the location of the person who possesses the portable terminal 30.

[0039] The display processing device 10 also includes an acquisition unit 11, a location identification unit 12, and a display processing unit 13. The acquisition unit 11 acquires the radio wave strength, which is the strength of the radio waves received by the mobile terminal 30 from each of the access points 50 of the wireless LAN installed indoors, from the mobile terminal 30 which is capable of communicating with the access points 50. The location identification unit 12 uses the radio wave strength to identify the location of the mobile terminal 30 indoors, in other words, the location of the subject who possesses the mobile terminal 30. The display processing unit 13 uses the indoor floor map and the location identified by the location identification unit 12 to display the location of the mobile terminal 30 on the floor map as the subject's location on the display device 20.

[0040] This makes it possible to display the location of a person even indoors where radio waves from satellites cannot reach.

[0041] [Example Display] The display processing device 10 may display not only the location of the subject as described above, but also other information on the display device 20.

[0042] Figure 8 shows an example of what can be displayed on the display device 20. For example, as shown in 801 of Figure 8, the display processing unit 13 may display the location history of the subject on the floor map based on the log information 144. In the example shown in 801, it is shown that Ms. E was in the meeting room shown on P11 from 9:00 to 10:00, then in the examination room shown on P12 from 10:10 to 10:30, and then in the large conference room shown on P13 from 11:00 to 12:00. The history to be displayed may include movement history, time spent, movement trajectory, etc.

[0043] Furthermore, as shown in 802, the display processing unit 13 may display the subject's behavioral tendencies on the floor map based on the subject's log information 144. In the example shown in 802, the behavioral tendencies of person A on Thursdays are shown as circles on the floor map. Here, the larger the diameter of the circle, the longer the time spent at that location. In the example in 802, it is shown that on Thursdays, person A often spends the longest time at the location shown in P31, the shortest time at the location shown in P32, and a moderate amount of time at the location shown in P33. The behavioral tendencies may also be displayed as a heatmap based on the subject's stay time and frequency. The behavioral tendencies may also be derived using map data that shows the relationship between coordinates and names, which is included in the floor map.

[0044] Furthermore, as shown in 803, the display processing unit 13 may display the subject's locations and time spent in a graph based on the subject's log information 144. In the example shown in 803, it is shown that person A spent 3 hours in the workroom, 2 hours in the examination room, and 1 hour in the conference room.

[0045] Furthermore, the display processing unit 13 may display a prediction of the subject's future movements based on the subject's log information 144. For example, it may display messages such as "There is a high probability that the subject will be in the laboratory on Thursday" or "There is a tendency for the subject to work from home on Friday."

[0046] Furthermore, the display processing unit 13 may indicate the subjects who were present in a predetermined area at a predetermined date and time based on the subject's log information 144. For example, 205 in Figure 2 above shows that at 12:00 on July 23rd, Mr. O, Mr. P, Mr. Q, and Mr. R were on the 6th floor of the head office.

[0047] Furthermore, the display processing unit 13 may cause the display device 20 to display whether the subject has entered or left the first area, based on the subject's current location. The first area may be a specific region or the area surrounding a specific person.

[0048] Furthermore, the display processing unit 13 may, based on the subject's log information 144, display a warning on the display device 20 when the subject's stay time in the second area exceeds a predetermined time. This allows for management of stay time in dangerous locations, management of working hours, etc.

[0049] [Embodiment 2] Other embodiments of this disclosure are described below. For convenience of explanation, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated.

[0050] Figure 9 shows an overview of the display system 1A according to this embodiment. Figure 9 is a functional block diagram showing the main components of the display system 1A. As shown in Figure 9s, the display system 1A according to this embodiment includes, in addition to the display system 1 described above, a detection device 40 for detecting the subject's biometric information. The detection device 40 is, for example, a smartwatch. Figure 10 shows an example of the detection device 40. Figure 10 shows an example where the detection device 40 is attached to the subject's wrist. The detection device 40 detects the subject's biometric information, such as heart rate and step count, and transmits it to the display processing device 10A. The detection device 40 and the display processing device 10A can communicate via the internet or the like. The detection device 40 is also associated with the owner of the mobile terminal 30. This association may be performed, for example, by adding identification information to identify the detection device 40 in the terminal information 141 described above.

[0051] In addition to the display processing device 10 described above, the display processing device 10A includes a state determination unit 15, and the determination information 145 is stored in the storage unit 14A.

[0052] The display processing device 10A displays the subject's biometric information, acquired from the detection device 40, along with the subject's location, on the display device 20. Furthermore, if there are multiple subjects and the locations of the subjects are displayed in a list, the display processing device 10A may include the biometric information of each subject in the list display.

[0053] The status determination unit 15 uses the determination information 145 to determine whether the subject's heart rate has exceeded the second threshold, and if it has, it notifies the display processing unit 13 accordingly. When the status determination unit 15 notifies the display processing unit 20 that the subject's heart rate has exceeded the second threshold, it displays a warning on the display device 20. The warning may be displayed on the floor map or on the map, or it may be displayed as a message.

[0054] In other words, the display processing device 10A includes a state determination unit 15 that determines whether or not the subject's heart rate has exceeded a second threshold, and if the subject's heart rate exceeds the second threshold, the display processing unit 13 causes the display device 20 to display that the subject's heart rate has exceeded the second threshold.

[0055] Judgment information 145 is information that stores the second threshold for each subject. In other words, the second threshold is set for each subject. Furthermore, the second threshold may be set according to the subject's age, gender, and their normal heart rate, etc.

[0056] Furthermore, when the detection device 40 detects that the subject has fallen and transmits a fall signal indicating this, the display processing device 10A may acquire the fall signal and display on the display device 20 that the subject has fallen. The display may be shown on a floor map or on a map along with the subject's location, or it may be shown as a message. The configuration by which the detection device 40 detects the subject's fall is possible using known technology, so a detailed explanation will be omitted, but for example, the detection device 40 can be equipped with an accelerometer (not shown), and detection can be performed using the measured value (instantaneous value) of the accelerometer. Alternatively, in addition to the accelerometer, a gyro sensor (not shown) may be equipped, and the measured value (tilt) of the gyro sensor may also be used to detect the subject's fall.

[0057] In other words, when a fall signal is transmitted from the detection device 40, the acquisition unit 11 acquires the fall signal, and the display processing unit 13 displays on the display device 20 that the person has fallen.

[0058] Furthermore, the detection device 40 may display an emergency assistance request button (SOS button), and when the SOS button is pressed, it may emit an emergency signal. When an emergency signal is emitted, the display processing device 10A may acquire the emergency signal and display on the display device 20 that the person is requesting emergency assistance. The display may be shown on a floor map or on a map along with the person's location, or it may be shown as a message.

[0059] In other words, when an emergency signal is transmitted from the detection device 40, the acquisition unit 11 acquires the emergency signal, and the display processing unit 13 displays on the display device 20 that the person is requesting assistance.

[0060] Furthermore, the display processing unit 13 may also display a warning on the display device 20 if the number of steps taken by the subject in the third area per predetermined time is below the third threshold. This allows for the management of emergencies such as injuries in dangerous locations.

[0061] Furthermore, if there are multiple owners of the detection device 40, and one of the detection devices 40 detects that the owner has fallen, the display processing device 10A may notify at least one of the mobile terminals 30 and other detection devices 40 located within a predetermined range from the detection device that the owner of the detection device 40 has fallen.

[0062] Furthermore, the display processing device 10 (10A) may also display the battery levels of the mobile terminal 30 and the detection device 40 on the display device 20, in addition to the location of the mobile terminal 30.

[0063] [Example Display] Figure 11 shows an example of the display on the display device 20. In this embodiment, Figure 11 corresponds to the example of the list display in Embodiment 1 described above (204 in Figure 2). As shown in Figure 11, in this embodiment, in addition to the subject's name, building and floor number, and location details, the subject's heart rate, heart rate acquisition time, today's step count, step count acquisition time, presence or absence of SOS notification, and SOS notification time are shown in association with each other.

[0064] Figure 12 shows an example of the display on the display device 20. Figure 12 shows an example of what is displayed on the floor map. Figure 1001 shows that Person D is requesting "SOS (Emergency Assistance Request)", or that Person D's heart rate has exceeded the second threshold and is 122, or that Person D has fallen, along with Person D's current location.
