JP6482862B2 - Content transfer method - Google Patents

Description

  The present invention relates to a content transfer method in which a digital address is given to an actual “thing” and an intangible content, for example, a sense of memory of the user can be linked (transferred) to the “thing”.

  There are a huge number of books in the house of the three brothers of AR (the eldest son), Tomu Kawada. Of course, there are bookshelves that make it happen, but because the number of books is so huge, there are many cases where you can't find the book you want.

  There is a means of “search” when “search” is performed in the current IT society. Google is a representative example, but it is a means of obtaining information by accessing the Internet using a personal computer and transferring the character string or image data of the desired information to the search system. However, this is a reality for individual users. It is not tied to physical life (mass).

  That is, the digital ones will not fade or deteriorate. However, "things" and "memory" that we use in daily life are used for a long time, and the process of life is gradually carved into it, so that it deteriorates or fades. It happens that love increases and memory becomes stronger.

  This is something we can share from our experience without explaining it in real life, but there is no “degradation” in digital that can be imprinted in our memory.

  Kawada wondered if there was a way to identify the unique things and memories, rather than the search and information according to this more real society.

What should I do?
Kawada thought that his feelings and memories he felt now would be stronger if he was linked to the reality in his life. In other words, not only information that does not deteriorate, such as digital information, but in addition to that, what can have a real shape and mass? It was thought that this could add the value of “deterioration” that digital is not good at.

  FIG. 1 shows a car navigation device 3 installed in a taxi with map information 2 (“content” of the present invention) around the destination displayed on the mobile terminal 1 by a passenger who wants to tell the destination in the taxi. This is an example in which a bune is transferred to a digital address (unique URL) of (a “display device” of the present invention) and displayed on the car navigation device 3.

When the operation in this case is described in accordance with the description of the invention described in the claims, it is as follows as shown in the flowchart of FIG.
(1) A step of associating the mobile terminal 1 with a specific digital address on the Internet (the mobile terminal Web server 6 having a unique URL) (step S1 in FIG. 2),
(2) The spatial position information processing server 4 specifies the spatial position of the portable terminal 1 based on the spatial position specifying information received from the portable terminal 1 and also stores the digital address (URL) of the portable terminal 1 at this spatial position. (Step S2 in FIG. 2)
(3) The spatial position information processing server 4 specifies the car navigation device 3 on the receiving side based on the relationship between the spatial position of the mobile terminal 1 and the spatial position of the car navigation device 3, and the digital address of the car navigation device 3 (Step S3 in FIG. 2) for identifying (Web server 5 for car navigation having a unique URL),
(4) When a passenger inputs an instruction to transmit map information 2 to the car navigation device 3 on the mobile terminal 1 (for example, flick operation A), the mobile terminal 1 or the server 4 transmits to the car navigation device 3 A step of uploading the map information 2 desired to the digital address (car navigation web server 5) of the car navigation device 3 via the digital address of the portable terminal (web server 5 for portable terminal) (step S4 in FIG. 2);
(5) A step of downloading the map information 2 uploaded to the digital address (car navigation Web server 5) of the car navigation device 3 to the car navigation device 3 and displaying it on the display (step S5 in FIG. 2).

  According to each of the above steps, the destination map information 2 which is intangible digital information displayed on the mobile terminal 1 as indicated by β is obtained by performing a flick operation as indicated by α in FIG. It is possible to realize such an operation that the car navigation device 3 is displayed as if it is flying.

  FIG. 3 is a diagram showing a system configuration for executing the above steps. In order to execute the above steps, the spatial position information processing server 4 includes a spatial mediation transmission information DB 8, a spatial position tag DB 9, a digital address DB 10, a digital address matching unit 11, and a content transfer unit 12. . Hereinafter, each of these configurations and operations will be described in detail together with the above-described steps.

(1) “Step of associating mobile terminal 1 with a specific digital address (unique mobile terminal URL) mobile terminal web server 6 on the Internet (step S1 in FIG. 2)” As described above, the feature of the present invention Is to give each “thing” a unique digital address. In this embodiment, the “thing” is the mobile terminal 1 and the car navigation device 3, and the digital address is the URL (Uniform Resource Locator) of the Web servers 5 and 6.

  In this embodiment, a unique URL is assigned to the mobile terminal 1 and the car navigation device 3 in advance. However, it may be assigned when the next spatial position is detected or thereafter.

(2) “The spatial position information processing server 4 to which the mobile terminal 1 is connected specifies the spatial position of the mobile terminal based on the spatial position specifying information received from the mobile terminal 1, and the mobile terminal 1 Step for associating with digital address (step S2 in FIG. 2) In this step, the “spatial position” of the portable terminal 1 is detected by the spatial position information processing server 4 and the information of the portable terminal 1 is stored in that space. Is done.

  This “storing information in space” means that the footprint (space position tag) of the terminal device 1 is virtually left in our actual activity space. For example, when the user holds the portable terminal 1 and is located in a certain environment space as shown in FIG. 4, the sound, light, color, and ultrasonic waves peculiar to the space received by the portable terminal 1 are received. The space-mediated transmission information composed of the combination is decoded (analyzed), and it is specified what and where the space of the mobile terminal 1 at that time is. This information and the attribute information of the mobile terminal 1 itself are virtually left in the space as the space position tag P.

  In this embodiment, the decoding is executed when the spatial position information processing server 4 on the cloud receives the spatial mediation transmission information from the mobile terminal 1 and inquires the spatial mediation transmission information DB 8 for the spatial mediation transmission information DB 8. The For example, based on the combination of the specific background music and the specific lighting at the spatial position, the spatial position P is decoded as “in the convenience store A” or the like.

  Further, in this embodiment, as shown in FIG. 4, the mobile terminal 1 oscillates ultrasonic waves U1 and U2 by itself and detects the reflected ultrasonic waves, whereby a horizontal distance and a vertical distance to an adjacent obstacle are detected. It is comprised so that it can measure. Thereby, for example, it is possible to know in which position in the convenience store A the portable terminal 1 is located. This information is also used for specifying the spatial position P as spatially mediated transmission information. Thereby, as shown in FIG. 5, for example, it is possible to decode the specific position in the area A or the area B of the mobile terminal 1.

  When the user moves as shown in FIG. 5, the information received by the mobile terminal and the decoded information are tagged in the space as intermittent space positions P1 to P7 as shown in FIG. This example shows an example in which it is known from the received space-mediated transmission information that the region A has moved to the region B. This region B is, for example, a space in the taxi.

  As a result, the position of the terminal 1 at a certain point in time is virtually left as a space position tag P in the space, and the space in which the mobile terminal 1 exists and the position in the space , Which direction it is facing is identified.

  Therefore, the detection of this spatial position is performed by the following steps (1-1) to (1-4).

  (1-1) The step in which the portable terminal 1 receives spatially mediated transmission information composed of one or a combination of two or more of sound, color, light, and ultrasonic waves at least at the spatial position.

  (1-2) A step of detecting terminal attribute information including one or a combination of two or more of the time, tilt / direction, and acceleration at which the mobile terminal 1 receives the space-mediated transmission information.

(1-3) a step in which the mobile terminal 1 or the server 4 to which the mobile terminal 1 is connected identifies the spatial position of the mobile terminal 1 by decoding the received spatial mediation transmission information,
(1-4) A step in which the mobile terminal 1 or the server 4 to which the mobile terminal 1 is connected stores the attribute information of the terminal device 1 in association with the spatial position of the specified mobile terminal 1.

  Hereafter, each component of said (1-1)-(1-4) is demonstrated in order.

(1-1) “Process in which information communication device receives spatially mediated transmission information composed of a combination of two or more of sound, color, light, and ultrasonic waves at least at the spatial position” “Spatial mediated transmission information” In the above, sound, color, light, and ultrasonic waves (and combinations thereof) are mentioned, but this makes it possible to specify and define the space in which the information communication device exists. For example, in the case of a station, the background information, the illumination itself, the color thereof, and the transmission information of ultrasonic waves exceeding the audible range. The space can be specified and defined by these individual information and combinations thereof.

  Also, information can be received at high speed by combining plural (two or more) spatially mediated transmission information and diversifying it. That is, as described above, there is a limit in the amount of communication (communication speed) per unit time in the transmission means expressed by the binary number “010101. In order to cope with the estimated amount of information, it is necessary to diversify the information transmission means.

  In addition, by using the spatially mediated transmission information, a physical line such as the Internet becomes unnecessary, and communication can be performed beyond the standards of the OS and terminals. According to this method, information such as signage overflowing in the city can be received one after another.

  In addition, in the case of spatially mediated transmission information, it is necessary to consider the sunlight and various noises and noise interference in the living environment. In the present invention, in order to cope with this problem, a plurality of communication means such as “sound”, “ultrasonic wave”, “color”, and the like work in a complementary manner, so that those noises can be filtered out.

  In this embodiment, the mobile terminal 1 itself includes an ultrasonic transmitter, and detects the ultrasonic waves reflected in the horizontal direction and the height direction according to the orientation of the terminal, and measures the distance to the obstacle. Can be done. The ultrasonic wave received at this time is also included in the spatially mediated transmission information. By providing such a function, it is possible to measure the exact position of the information communication device in the space, and in some cases, it is possible to measure the dimensions of the room.

(1-2) “Step of detecting terminal attribute information composed of one or a combination of at least the time, inclination / direction, and acceleration at which the information communication device receives the space-mediated transmission information” The step is a step of recording attribute information of the mobile terminal 1 when the mobile terminal 1 receives the space-mediated transmission information. Specifically, it is at least one of time, tilt / direction, and acceleration when the space-mediated transmission information is received. In addition to this, video information captured by the portable terminal may be recorded. Also, information that allows a third party to specify the terminal itself, such as a telephone number or personal ID, may be recorded.

  In the present invention, the portable terminal 1 is associated with a unique digital address (the URL of a specific Web server 6 on the Internet), and this digital address is stored in the digital address database 10 of the server 4. The If the mobile terminal 1 does not have a digital address at this time, the server 4 determines a unique digital address for the mobile terminal 1. A unique digital address can be assigned to each spatial position.

(1-3) “Information communication device or server to which this information communication device is connected identifies the spatial position of this mobile terminal by decoding the received spatially mediated transmission information” In this step, The spatially mediated transmission information received in the step (1) is decoded (decoded), and the spatial position P of the mobile terminal 1 is specified.

  For example, assume that the space is a specific convenience store (area A). In this case, music that flows in the convenience store, colors of floor and ceiling display shelves, lighting, and other ultrasonic waves that exceed the audible range are received by this communication device. Further, the distance to the floor or wall is measured by detecting the reflected wave of the ultrasonic wave transmitted from the portable terminal 1.

  In this embodiment, the spatial position information processing server 4 stores a database 8 (spatial identification information) storing sound, light, color, and ultrasonic identification information for identifying spatially mediated transmission information specific to each space. Database) is prepared in advance, and the portable terminal 1 inquires of the server 4 for the space-mediated transmission information and identifies / specifies the space. At this time, the reflection of the ultrasonic wave is used for specifying the position in the space. For example, the position in the store is specified by the distance to the obstacle in the water ratio direction measured by ultrasonic waves. Also, the height of the terminal can be detected. Similarly, in the case of a taxi (area B), it is specified that the mobile terminal 1 is present in the taxi based on the atmosphere information in the taxi.

  The mobile terminal 1 itself or the server 4 may perform the decoding of the space-mediated transmission information.

  In the present invention, as described above, a communication protocol is defined so that noises drifting in the space can be filtered out by combining a plurality (two or more) of spatially mediated transmission information with each other. It is executed according to the protocol.

(1-4) “A step in which the mobile terminal or the server to which the information communication device is connected stores the attribute information of the terminal in association with the spatial position of the specified mobile terminal” Attribute information of the mobile terminal 1 Is at least a combination of one or more of information for identifying the terminal (telephone number, personal ID, etc.), position information that can be detected by the terminal itself, direction (tilt) information, and acceleration information. By associating this with the space position P, it becomes possible to leave information on the terminal virtually in space. This information is accumulated in the spatial position tag database 9 of the server 4. In this embodiment, the URL (digital address) of the Web server associated with the portable terminal 1 is also stored in the server as the digital address database 10.

(3) “The spatial position information processing server 4 specifies the receiving car navigation device 3 based on the relationship between the spatial position of the mobile terminal 1 and the spatial position of the car navigation device 3, and Step of identifying address (Web server 5 for car navigation system having unique URL) (step S3 in FIG. 2) ”In the above (1), the spatial position information of the mobile terminal 1, that is, the spatial position tag is the spatial position information processing server. 4 is stored in the same manner as the spatial position information of the car navigation device 3, that is, the spatial position tag, and is registered in the server 4 that the car navigation device 3 is installed in the taxi. Has been. As described above, the car navigation device 3 is also given a unique digital address (a URL of a specific Web server 5), which is also stored in the digital address database 10 of the server 4.

  The space position information and the digital address of the car navigation device 3 may be registered manually or automatically by a taxi company or a car navigation manufacturer, for example.

  When it is detected in the step (2) that the spatial position of the mobile terminal 1 is in the specific taxi, the digital address matching unit 11 is installed in the taxi as the nearest display device. The car navigation device 3 is identified, and as a result, the digital address of the portable terminal 1 and the digital address of the car navigation device are linked.

  Matching between the portable terminal 1 and another display device to which content is transferred from the terminal 1 (in this example, the car navigation device 3) is most suitable when there are a plurality of display devices around a predetermined rule. When there is no adjacent device, no adjacent device, etc., this is done based on the rules of the device or the like in the extension line of the height or direction of this device.

  For example, when there are a plurality of display devices within 2 m, the display device is connected to an extension line in the direction in which the portable terminal 1 is facing. Further, when there is no other display device in the vicinity, the display device is connected to the display device closest to the mobile terminal or the display device existing on the extension line in the direction in which the mobile terminal is facing.

  In this matching, it is determined whether the other display device permits matching with a specific mobile terminal. For example, even a display device having a digital address may allow only matching with a mobile terminal of a specific manufacturer or model.

(4) “When a passenger inputs an instruction to transmit the map information 2 to the car navigation device 3 on the portable terminal 1 (for example, flick operation A), the portable terminal 1 or the server 4 sends to the car navigation device 3 A step of uploading the map information 2 to be transmitted to the digital address (car navigation web server 5) of the car navigation device 3 via the digital address of the portable terminal (web server 5 for portable terminal) (step S4 in FIG. 2). In the state where the portable terminal 1 and the car navigation device 3 are matched as described above, a predetermined operation on the terminal 1, for example, an operation in which the user flicks the screen to the car navigation side with the fingertip (FIG. 1). For example, a dedicated application installed on the mobile terminal 1 or an add-on installed on the browser ( Band terminal side transfer unit 13), first, on the portable terminal for Web server 6 is a digital address of the terminal 1, to Apurodo the map information 2. At this time, the map information includes at least map data (coordinates and address data) indicating the destination, but may include images and moving images. It may include atmosphere information (image, sound, display screen) currently captured by the mobile terminal 1.

(5) “Step of downloading the map information 2 uploaded to the digital address (car navigation Web server) of the car navigation device 3 to the car navigation device and displaying it on the display (step S5 in FIG. 2)” The content transfer unit 12 provided in the server 4 transfers / uploads the map information 2 uploaded to the digital address (Web server 6) of the mobile terminal to the digital address (Web server 5) of the car navigation device 3.

  An application (car navigation side transfer unit 14) installed in the car navigation device 3 monitors the update of the car navigation web server 5, and the uploaded map information 2 is downloaded to the car navigation device 3 and displayed on the display. To do.

  Thus, as described above, when the user performs a flick operation as indicated by α in FIG. 1, the destination map information 2 displayed on the portable terminal 1 as indicated by β jumps to the car navigation device 3 as a bounce. Can be realized.
