FIG. 2 shows functional blocks of the information transfer system. The information transfer system includes various sensor groups worn by the user U, an information display unit 102, and an information terminal 101 having a control device function.

  First, a device and a sensor group worn by the user U will be described. The user U includes an indoor / outdoor sensor 110, a GPS (Global Positioning System) 111, a foot pressure sensor 112, a speech / mastication / specific environmental sound sensor 113, a wristwatch-type motion measurement sensor 114, a heart rate Number sensor 115, body temperature sensor 116, peripheral skin temperature sensor 117, sweat sensor 118, facial color sensor 119, pupil size sensor 120, ambient humidity sensor 121, ambient humidity sensor 122, and ambient light intensity sensor 123 are worn on the body. . These sensors are hereinafter referred to as “sensor 110 etc.” as appropriate. The sensor 110 and the like correspond to behavior measuring means, biological information measuring means, and environment measuring means. The user U wears the information display unit 102 in the vicinity of one eye of the head.

(Indoor / outdoor sensor)
The indoor / outdoor sensor 110 detects and determines whether the user U exists indoors or outdoors. The indoor / outdoor sensor 110 includes an irradiation unit, a reception unit, and a determination unit. For example, the irradiating unit irradiates ultrasonic waves toward the object to be reflected and the ceiling, and determines and measures the time until the light is reflected and returned. The indoor / outdoor sensor 110 is not limited to ultrasonic waves, and may use the following method.
(1) Active light method (application of general distance sensors) that detects reflection by irradiating laser or infrared light.
(2) Passive UV method for detecting light in the UV region (utilizing different amounts of UV light indoors and outdoors),
(3) Passive infrared method (utilizing the difference in temperature between the ceiling and the sky) that measures the upward space temperature (the amount of infrared rays from clouds, etc.) with a pyroelectric sensor,
(4) A passive noise method in which noise is measured with a microphone (utilizing that the noise spectrum pattern is different indoors and outdoors).

(GPS)
User U wears GPS 111 on his body. The location of the user U can be detected by the GPS 111. Further, a location information service of a mobile phone can be used instead of the GPS 111. The GPS corresponds to a position measuring unit.

(Foot pressure sensor)
The foot pressure sensor 112 detects the pressure distribution of the sole applied to the shoes worn by the user U. The foot pressure sensor 112 measures and determines the standing state, the sitting state, and the walking state of the user U.

(Speech / mastication / specific environmental sound sensor)
The utterance / mastication / specific environmental sound sensor 113 measures the possibility that the user U is speaking, that is, talking, or chewing, ie, eating. Further, the possibility of where the user U is in a plurality of previously registered environments is measured.

  The utterance / mastication / specific environmental sound sensor 113 is an earphone sensor that is worn on one ear of the user U. A bone conduction microphone and an external sound microphone are built in one housing of the earphone type sensor.

  The bone conduction microphone detects body sounds. The body sound is vibration that is generated from the body and propagates through the body when the user U speaks and chews. Specific examples of body sounds include vocal cord vibration, the sound of teeth biting food, the sound of food passing through the throat, the sound of movement of the chin joint, and the like.

The external sound microphone detects external sound in the environment where the user is present. In addition to environmental noise, the external sound includes vibrations that propagate outside the body, that is, sound in accordance with the utterance of the user U.
When the power in the first unit time T ₁ (for example, 100 ms) of the sound captured by the bone conduction microphone and the external sound microphone is P ₁ and P ₂ , respectively, P ₁ is larger than the first threshold C ₁ , and, the P ₂ when the second is smaller than the threshold value C ₂ is assumed that detected the sound associated with chewing, adds the mastication detection number N _1. Then, by using the mastication detection rate (N ₁ × T ₁ / T ₂ ) in the second unit time T ₂ (for example, _{2 s} ) as a measurement value, this measurement value is the possibility of mastication in the second unit time T ₂ . Can be shown.
Similarly, when P ₁ is larger than the third threshold C ₃ and P ₂ is larger than the fourth threshold C ₄ , it is assumed that the sound accompanying the utterance is detected, and the utterance detection number N ₂ is added. To do. Then, by using the mastication detection rate (N ₂ × T ₁ / T ₂ ) in the second unit time T ₂ (for example, _{2 s} ) as a measurement value, this measurement value can be uttered in the second unit time T ₂ . Can be shown.
Furthermore, the environment surrounding the user U can be estimated to some extent by analyzing the level and frequency of the sound captured by the external sound microphone. For example, the level fluctuation pattern and frequency distribution of noise captured by an external sound microphone in a train, bus, or airplane were measured in advance, and the external sound microphone actually worn by the user U was captured. By comparing the sound with the previously measured fluctuations and frequency distribution, it is possible to estimate which vehicle the user is in. For example, the correlation coefficient with the noise in the airplane is used as the measured value. Then you can show the possibility of being in an airplane.

(Arm-mounted motion measurement sensor)
The arm-mounted motion measurement sensor 114 (hereinafter referred to as “motion measurement sensor” as appropriate) detects the movement of the user U's arm. The motion measurement sensor 114 includes an acceleration sensor and an angular velocity sensor. Then, it is possible to more accurately identify the daily action and walking state of the user U together with the detection result of the foot pressure sensor 112 described above. Examples of the method of wearing on the arm include a wristwatch type or a type attached to the arm.

(Ambient light intensity sensor)
The ambient light intensity sensor 123 measures the ambient light intensity using, for example, a sensor using a photoelectric element.

(Information transfer)

In addition, when connecting to the charger to charge the power supply of the information terminal 101 of the present invention, it is possible to connect to the external database 220 at the same time. In this case, a power line LAN or the like can also be used for connection of a dedicated communication line.

(Information terminal equipment)
The information terminal 101 will be described. The information terminal 101 in this information transfer system has four functions.

The third function is a function for selecting and taking in information from an external database based on the calculation result. The fourth function is a function for communicating with the outside to acquire information and storing it in the internal information storage unit 208 of the information terminal 101. The internal information storage unit 208 corresponds to information storage means.

  Here, the information terminal 101 can incorporate all of the first to fourth functions. For example, the information terminal 101 has only the first and fourth functions, and the measurement results of the second various sensor groups. An external server may have a function of calculating based on the above and a function of selectively acquiring information based on the third calculation result. In this method, the measurement results of various sensors are transmitted from the information terminal 101 (control device) to the external server together with the acquisition date and time. In addition, information from the external server is selected by information selection means built in the external server and transmitted to the information terminal 101.

  In this embodiment, an information request from the information selection / acquisition unit 209 or measurement results of various sensors is transmitted from the information terminal 101 (control device) to the external database 220 via the external communication unit 212.

The external communication unit 212 corresponds to a communication unit.

  As described above, in the information transfer system, each function described above can be installed in either the information terminal 101 or the external server 220.

(Sensor information aggregation function)

For this reason, an analog / digital conversion function is added to the sensor. Further, a transmission / reception function for wirelessly communicating with the information terminal 101 (control device) is added to each sensor unit. The wireless communication between each sensor and the information terminal 101 (control device) performs multiplex communication by any one of time division, frequency division, or spectro-spreading.

  In addition, it is desirable that the behavior measurement unit 201 captures past data of measurement results from the environment measurement unit 203 that measures the user's surrounding environment as data at the time of calculation.

  The biological information measuring unit 202 includes a heart rate sensor 115, a body temperature sensor 116, a peripheral skin temperature sensor 117, a sweat sensor 118, a face color sensor 119, and a pupil size sensor 120.

  The environment measurement unit 203 includes an ambient temperature sensor 121, an ambient humidity sensor 122, and an ambient light intensity sensor 123. Thus, according to a preferred aspect of the present invention, it is desirable that the environment measurement unit 203 that measures the surrounding environment of the user U includes any one of temperature, humidity, luminous intensity, external sound, and indoor / outdoor sense. .

  Each sensor 110 and the like further includes a communication unit 211 that communicates (communicates) with the information terminal 101 wirelessly. The communication unit 211 has a transmission / reception function. Wireless communication between each sensor 110 or the like and the information terminal 101 can be performed by multiplex communication by any one of time division, frequency division, or spectrospreading.

  Further, at least a part of or all of the measurement values of each measuring means and / or a part of or all of the measurement result storage information are used for the calculation unit 205 to perform at least a numerical multiplication function and a numerical addition function. It is preferable to include.

  In addition, the calculation unit 205 that performs calculation using at least some or all of the measurement values of each measurement unit and / or some or all of the measurement result storage information further includes a coefficient storage unit that stores a coefficient 206 is a calculation unit 205 that multiplies the measurement result and / or a part or all of the values of the measurement result storage unit 204 by the coefficient of the coefficient storage unit 206, adds the multiplication results, and outputs a multidimensional calculation result. Preferably there is.

  Further, according to the present invention, the coefficient stored in the coefficient storage unit 206 that stores the coefficient is a coefficient rewriting unit based on the calculation result of the second calculation unit 207 that calculates using part or all of the calculation result. It is preferable to be rewritten by 207.

  In addition, according to the present invention, it is preferable that the information selection / acquisition unit 209 for selecting information to be downloaded is provided, and the result of the calculation unit 205 is input to the information selection / acquisition unit 209.

  Moreover, it is preferable that the downloaded information can be further input to the information selection / acquisition unit 209 so that the information to be downloaded can be further selected based on the downloaded information.

  Next, a processing procedure in the present embodiment will be described. FIG. 3 is a flowchart showing the flow of processing.

  In step S301, the calculation unit 205 takes in the measurement results from the sensors 101 and the like. In step S302, the captured measurement result is converted from an analog output to a digital output. As described above, each sensor 101 or the like may have an analog / digital conversion function.

  In step S304, the calculation unit 205 performs a calculation according to a procedure described later. Calculation results are stored in the calculation result storage unit 213, and measurement results are stored in the measurement result storage unit 204. In Steps S303, S305, and S306, individualized calculations can be performed on the user using current and / or past calculation results and measurement results. Details of such calculation for personalization will be described later. In step S307, the information selection / acquisition unit 209 retrieves information from the external information database 220 according to a procedure described later based on the calculation result. In step S308, the extracted information is stored in the internal information storage unit 208.

(Calculation function)
Next, calculation processing performed by the calculation unit 205 will be described. The calculation unit 205 includes a part or all of measurement values from at least one of the behavior measurement unit 201, the biological information measurement unit 202, and the environment measurement unit 203 and / or measurement results stored in the measurement result storage unit 204. Calculation is performed using a part or all of the stored information and / or information stored in the information storage means of the information terminal. This corresponds to step S304 in FIG.

Specifically, the arithmetic unit 205 has a function of multiplying and digitizing signals from the digitized sensors 101 and the like. For example, as shown in the following equation (1), a product-sum calculation of the numerical value X _j of the measurement result from each sensor 101 and the like and the coefficient A _ij represented by a two-dimensional matrix (matrix) is performed. Then, the result of product-sum calculation is calculated as an n-dimensional vector Y _i using multidimensional coordinates. Note that i is an i coordinate in an n-dimensional space. In the numerical value X _j , j is a number assigned to each sensor 101 or the like.

(Measurement result)
Part or all of measurement values from at least one of the behavior measurement unit 201, the biological information measurement unit 202, and the environment measurement unit 203, and / or a part of measurement result storage information stored in the measurement result storage unit 204 Or, when all the numerical values are used for calculation, but not all sensors are connected, when an abnormal value appears in a part of the measured value, or when calculating using a part of the measured value , X _i is preferably calculated using a predetermined default value. For example, if a specified range is specified and the numerical value is out of the range, it is determined that the measurement value is abnormal, or the time-series measurement value changes over time by a certain threshold. Is determined. Alternatively, as another method, a plurality of coefficient matrices for calculation may be prepared in accordance with the type or number of sensors, and calculation may be performed using a coefficient matrix selected according to the type or number of sensors.

(Y value of the calculation result)
The calculated Y value of the Y coordinate may be a numerical value having no conceptual meaning such as fatigue or busy, but may have a conceptual meaning depending on the setting of the A coefficient. For example, each A coefficient multiplied by the X value of heart rate, sweating, and body temperature is set to a value larger than the A coefficient for other measurement values. The Y value multiplied / added by this increases as the measured values of heart rate, sweating, and body temperature increase, and the Y value represents the so-called “excitability”. And the Y axis can be positioned as excitement. Also, if the A coefficient for the measured value of the speech / mastication / specific environmental sound sensor's speech and mastication and the foot pressure sensor is large, the measured value of the speech / mastication is high, When there is no movement of the foot pressure sensor, the corresponding Y value calculated indicates that the person seems to be sitting and talking. In addition, when the measured values of speech and mastication are low and the measured value of the foot pressure sensor is low, the corresponding Y value calculated is low, and it can be estimated whether the person is thinking quietly or is sleeping. . In this way, by further increasing the types of sensors, each Y value, in other words, the Y-axis can be made to generally correspond to the contents of the user's actions and emotions.

(Information selection / acquisition means)
Next, extraction of information from the external information database 220 will be described. The output of the calculation unit 205 is expressed as multidimensional coordinates as described above. The information selection / acquisition unit 209 compares the output coordinates with the attribute coordinates of the information stored in the external information database 220.

  As shown in FIG. 4, when the coordinates of the output calculation result exist within a predetermined range of coordinates added to information in the external information database 220, the information is determined as information to be acquired. And get.

FIG. 4 shows information existing within a predetermined width of coordinates in the vector space. For example, c to d for _{Y 3} axis, the _{Y 5} axis to b, in the range of e~f for _{Y 8} axes, when output operation result is present, the information X is selected. The display unit 210 displays the selected information X.

  The determination of coordinates and the extraction of information are performed at a preset time interval or when the output value of the calculation unit 205 changes more than a predetermined value. FIG. 4 shows only three axes for convenience of illustration. As can be easily seen from FIG. 4, the information X is located in the ranges of ab, cd, and ef of each axis.

  Further, when the output calculation result does not exist within a predetermined range of the vector space, information closest to the calculation result is selected. Here, whether or not it is close to the calculation result is determined by a multidimensional distance between the coordinates of the calculation result and the center coordinates of the area where information exists around the calculation result.

In the present embodiment, a second calculation unit 207 can be further provided. The second calculation unit 207, based on the coefficient _{A nm} already obtained, for calculating a new coefficient _{A nm.}

The second arithmetic unit 207 also has a function as a coefficient rewriting unit for rewriting the coefficient stored in the coefficient storage unit 206. By repeating the procedure of the formula (2), the coefficient A _nm is sequentially rewritten. This corresponds to steps S305 and S306 in FIG.

In the formula _{(2), A nm} are calculation coefficients to date, the left side of _{A nm} gives a new operation coefficient. This calculation is an example, and the present invention is not limited to this method.

Furthermore, for example, C _nm can be given as the following equation (3) as a function of the change amount ΔX _i of the measured value X _i .

C _nm = f (ΔX ₁ , ΔX ₂ ,..., ΔX _i ,... ΔX _m ) (3)

Here, the change amount ΔX _i of the measurement value X _i is defined by the change amount between the measurement result and the measurement result storage information.

In other words, the change amount [Delta] X _i of the measured value X _i, expressed a measurement result in a state before giving the information by the information display system to the user U, the state after the given information a difference between a measurement result Yes. This difference corresponds to the degree of influence of this information on the user. Based on this degree of influence, C _nm varies and is determined.

  In addition, the present invention is not limited to this, and the second calculation unit 207 may perform calculation using a change amount between the calculation result and the calculation result storage information as in the following equation (4). Here, the calculation result storage unit 213 stores the calculation result by the calculation unit 205 as calculation result storage information.

C _nm = f (ΔY ₁ , ΔY ₂ ,..., ΔY _i ,... ΔY _m ) (4)

In other words, the change amount [Delta] Y _i of computation result Y _i represents the calculated result of the previous state which gives the information by the information display system to the user, the difference between the state calculation result of after giving information . This difference corresponds to the degree of influence of this information on the user. Based on this degree of influence, C _nm varies and is determined.

  In the above-described calculation, it is desirable to use both the current calculation result and the calculation result recorded in the past situation. Thereby, a change and direction of a user's situation can be acquired more correctly. In other words, individualized information can be obtained according to each user.

Further, the calculation may be performed using both ΔX _i ΔY _i .
C _nm = f (ΔX ₁ , ΔX ₂ ,..., ΔX _i ,... ΔX _m , ΔY ₁ , ΔY ₂ ,..., ΔY _i ,... ΔY _m ) (5)

(Internal information storage)
In the internal information storage unit 208, so-called internal database, the information transferred / acquired from the external database 220 can be replaced with the previous information at the same address according to the instruction of the user U. It can also be stored at another address. It is also possible to detect the date and time attached to the information as an attribute and always replace it with new information. The internal information storage unit 208 corresponds to information storage means.

  This embodiment will be described in more detail. For example, consider a case where an action schedule that the user U goes out is stored in the system. Before going out, the system performs an operation using the behavior measurement value obtained by quantifying the schedule, transfers and acquires necessary information from the external database 220 based on the operation result, and acquires the internal information storage unit 208 (information Memory).

  In this case, for example, information such as weather forecasts, road information, and railway operation information, neighboring information of destinations, restaurant information, and the like are automatically acquired and stored, and information can be displayed to the user U as necessary. it can.

  Furthermore, the information (primary information) acquired and stored in this way can be further input to the calculation unit 205, and the next information (secondary information) can be acquired based on the calculation result. . For example, when weather information is first acquired and the weather information is raining, further calculation is performed and information about the rain, for example, a restaurant that can be reached without getting wet from the station, route information that does not care much about rain, etc. is appropriately selected. Transferred / acquired.

  Note that primary information (weather information in the above example) acquired from the external database 220 to select information to be acquired does not necessarily need to be stored in the internal information storage unit 208. For example, the primary information is input to the second calculation means prepared on the external database 220 side, and the second information selection / acquisition means similarly prepared on the external database 220 side receives the secondary information based on the calculation result. The information may be selected / obtained and stored in the internal information storage unit 208 in the information terminal 101 via the communication unit.

  Still another embodiment will be described. When listening to music on the information terminal 101, the behavior measuring unit 201 that measures the movement of each part of the body of the user U when listening to the music of the user U, and the biological information measurement that measures the biological information of the body of the user U The unit 202 records each measured value for the song being listened to.

  Information based on the calculation result of the measurement value is selected and acquired from the external database 220. In this example, the information is a music piece, and the coefficient of the calculation unit 205 is determined so that the calculation result based on the measurement result is selected based on the interest and excitement level of the user U. Therefore, according to the present invention, for example, a new song or the like that seems to suit the interest and preference of the user U is downloaded.

  In another example of such music distribution, for example, while the information terminal 101 is placed on the cradle and charged, predetermined music can be downloaded from the external database 220 according to the above-described procedure. The downloaded music is stored in the internal information storage unit 209. The user U selects desired music from among stored and stored music. Further, music that is optimal for the situation of the user U may be automatically displayed (reproduced).

  In the information transfer system according to the present invention, behavior measuring means for measuring the movement of each part of the user's body, biological information measuring means for measuring the biological information of the user's body, and the surrounding environment of the user are measured. An environmental measurement unit is provided to measure the physical and mental state of the user and the environmental state surrounding the user, and at least a part or all of the measurement values of the measurement unit and / or the measurement result that is past information Information that is calculated by the calculation means using a part or all of the stored information, inputs the calculation result to the acquisition information selection function, and is really required by the user by communication means from an external database. It is possible to realize an information transfer system that can automatically acquire.

  As described above, the information terminal device according to the present invention includes a behavior measuring unit that measures the movement of each part of the user's body, a biological information measuring unit that measures the biological information of the user's body, and the user's body. It is useful for an information transfer system that acquires information that a user really needs by using an environment measuring unit that measures the surrounding environment.
