BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a display system and a display method using biospecific information according to the present invention will be described in detail with reference to the accompanying drawings.
[0019]
FIG. 1 shows a conceptual diagram of the overall configuration of the display system of the present embodiment. The display system shown in FIG. 1 includes a CRT (Cathode Ray Tube) display, a LCD (Liquid Crystal Displa: liquid crystal display), and a plasma for displaying characters and images (still images and moving images) that can be visually recognized by humans. The present invention is applied to a display (display device) 1 such as a display panel.
[0020]
More specifically, the display system is configured such that a user (operator) OP of the display 1 can change a living body that can change in response to display conditions (display size, resolution, display position, etc.) of characters and images on the display screen. EEG and biometric data that constitutes the measuring means of the present invention that measures and transmits unique information (biological data such as respiration, pulse, blood pressure, body temperature, etc. in addition to electroencephalogram, hereinafter referred to as "electroencephalogram and biometric data" as necessary). The transmitter 10 and the storage unit and the processing unit of the present invention for receiving and analyzing the transmitted measurement values of the brain wave and the biological data and generating a command for correcting the display conditions of characters and images according to the analysis result. The analysis and optimum value generation device 20 (receiving means 21, storage means 22, analysis and generation means 23, and transmission means 24), and in response to the generated correction command, generates characters and images under display conditions specified by the command. To display Comprising a display control unit 30 (reception means 31, the assembly means 32, signal generating means 33) for controlling the 示機 1 and.
[0021]
FIG. 2 shows a configuration example of the electroencephalogram & biometric data transmitter 10, FIG. 3 shows a configuration example of the analysis & optimum value generation device 20, and FIG. 4 shows a configuration example of the display control device 30, respectively.
[0022]
In the example shown in FIG. 2, the electroencephalogram & biometric data transmitter 10 includes an electroencephalogram & biometric data measurement function 11 for measuring electroencephalogram and biometric data, and a user identification code in the measured electroencephalogram and biometric data. An electroencephalogram & biometric data measurement conversion function 12 for applying and converting to a format that can be transmitted; and analyzing & generating an optimum value when the converted electroencephalogram and biometric data are satisfied at a preset time interval or a predetermined transmission condition. It comprises an electroencephalogram & biometric data transmission function 13 for transmitting to the device 20.
[0023]
Of these, the electroencephalogram & biometric data measurement function 11 and the electroencephalogram & biometric data measurement conversion function 12 include known medical examination devices and measurement devices such as an electrocardiogram measurement device, a pulse measurement device, a blood pressure measurement device, and an electroencephalography measurement device. Sensors) are applicable. In this case, for example, a plurality of sensors are employed. However, if a sensor method is used in which brain waves and biometric data are read from the surface of the living body and transmitted, the user OP can enjoy daily comfort with little awareness of the presence of the sensor. For example, each part (hand) of the body surface of the user OP such as a necklace-type sensor and a bracelet-type sensor capable of measuring data such as breathing, body temperature, pulse, blood pressure, etc. from the hand and neck, and a glasses-type sensor capable of measuring brain waves , Neck, ears, etc.). Further, if possible in the future, a chip-type sensor of an extremely small size (for example, about 1 mm in diameter and about 5 mm in length) that can be embedded in the body of the user OP is adopted, and this chip-type sensor is embedded in a predetermined position in the body. Then, the brain wave and the biological data may be periodically obtained from the body part.
[0024]
The measured values of the electroencephalogram and biometric data obtained by the plurality of sensors constituting the electroencephalogram and biometric data measurement function 11 are provided with the identification code of the user OP by the electroencephalogram and biometric data measurement conversion function 12 and are transmitted in a predetermined transmission format. After the conversion, the data is sent to the brain wave & biological data transmission function 13.
[0025]
The electroencephalogram & biometric data transmission function 13 is integrally formed in a business card large size card type transmitter (chest pocket transmitter) that can be put in a breast pocket, for example, and a plurality of electroencephalogram & biometric data measurement functions 11 are formed. A carrier wave of a predetermined frequency is modulated by the brain wave & biological data transmitted from the measuring instrument via the brain wave & biological data measurement conversion function 12, and a radio wave of the modulated signal can be transmitted.
[0026]
The analysis & optimum value generation device 20 includes a processor with a built-in program having, for example, a CPU and a memory (including a ROM holding various control / processing programs executed by the CPU and a RAM used as a work area of the CPU). In the example shown in FIG. 3, an EEG & biometric data receiving function 21 a as a receiving unit 21, an EEG & biometric data storage control function 22 a as a storage unit 22, and a measurement value accumulation DB (database) ) 21b, an analysis & optimum value generation function 23a as the analysis & generation means 23, and a signal creation & transmission function 24a as the transmission means 24. The measurement value accumulation DB 21b is configured by a storage medium such as an accumulation memory and a disk-type storage medium.
[0027]
The electroencephalogram & biometric data receiving function 21a receives radio waves transmitted from the electroencephalogram & biometric data transmitter 10, demodulates electroencephalogram and biometric data from the received signal, and outputs an internal signal (a predetermined format that can be processed by the apparatus 20). ) And sends it to the brain wave & biological data storage control function 22a.
[0028]
The electroencephalogram & biometric data accumulation control function 22a recognizes the user OP who is the sender of the measurement data converted into the internal signal based on the identification code given to the data and records the measurement on the measurement value accumulation DB 21b. Data is stored and stored in a predetermined format for each user OP.
[0029]
The analysis & optimum value generation function 23a analyzes according to a predetermined analysis algorithm (see later) whether or not the current measurement data is within a proper value range obtained from the accumulated data stored in the measured value accumulation DB 21b. If the measured data is not within the range of the appropriate value, the display conditions such as the character currently displayed on the display 1, the display size of the image, the resolution, and the display position are returned until the measured data returns to the range of the appropriate value. A command for correction is generated and sent to the signal creation & transmission function 24a.
[0030]
The signal creation & transmission function 24a converts the generated correction command into a device-specific signal for the display control device 30 and transmits the signal to the display control device 30.
[0031]
The display control device 30 is composed of, for example, a controller for a display (such as an LCD), and has a signal receiving function 31 a as a receiving means 31, a display assembling function 32 b as an assembling means 32, and a signal creating means 33. And a display signal creation & transmission function 33a.
[0032]
According to this configuration, when the signal receiving function 31a receives a device-specific signal for a correction command from the signal generating and transmitting function 24a, it determines whether the signal is abnormal. To the signal generation and transmission function 24a, and if there is no abnormality, the display assembling function 32b and the display signal generation and transmission function 33a display characters and images under the display conditions according to the correction command indicated by the signal. The data of the display screen to be newly assembled is converted to the device-specific signal for the display device 1 and transmitted to the display device 1. Thereby, the display 1 displays characters and images based on the signal from the display control device 30 under the display conditions according to the correction command.
[0033]
Next, the operation of the present embodiment will be described based on the time charts of FIGS.
[0034]
FIG. 5 illustrates a processing sequence of the brain wave & biological data receiving function 21a. In FIG. 5, when the measurement data from the electroencephalogram & biometric data transmitter 10 is received, the electroencephalogram & biometric data receiving function 21a decomposes the received data and classifies the data into items such as electroencephalogram, respiration, pulse, blood pressure and the like. Then, it is determined whether or not an error relating to processing such as measurement or transmission has occurred with respect to each measurement data. If there is no error, the processing shifts to processing by the brain wave & biological data accumulation control function 22a, and there is an error. If so, a signal for requesting retransmission of the measurement data in which the error has occurred is assembled and sent to the electroencephalogram & biological data transmission function 13 (steps St11 to St13). Thereby, the measurement data without error is sent to the brain wave & biological data accumulation control function 22a.
[0035]
FIG. 6 illustrates a processing sequence of the brain wave & biological data accumulation control function 22a. In FIG. 6, upon receiving the measurement data sent from the brain wave & biometric data receiving function 21a, the electroencephalogram & biometric data accumulation control function 22a identifies the user OP who is the sender and determines whether or not the user is a previously authorized person. , And sequentially determine whether the measurement data of each item is within a predetermined measurement range, and if the sender is an authorized person and the measurement data is within the range, assemble the measurement data as storage data. The data is written in the storage medium forming the measured value accumulation DB 22b. If there is no error at the time of writing this data, the measured values for each sender are arranged in a group based on the current values together with the current display size, resolution, and display position setting values, and stored in the measured value storage DB 22b. I will do it.
[0036]
In the above processing, if any of the sender is not the authorized person, the measurement data is out of the predetermined range, or there is a writing error, a preset error processing is performed (Steps St21 to St27).
[0037]
Therefore, according to the electroencephalogram & biological data accumulation control function 22a, the range of the transmitted measurement data is checked, and the display size, the display size, and the like are simply determined based on the current current value (initial default value). A process is performed in which a grouping is performed for each resolution and display position, and the data is arranged and stored in time series on the measurement value storage DB 22b.
[0038]
FIG. 7 illustrates the processing sequence of the analysis & optimum value generation function 23a, and FIG. 8 illustrates the processing sequence of the signal creation & transmission function 24a.
[0039]
In FIG. 7, the analysis & optimum value generation function 23a identifies a sender and, based on the accumulated data accumulated for each sender, calculates the brain wave system (measured brain wave value), the respiratory system (Measurement value of respiratory rate) and blood system (measurement value of pulse and blood pressure) are sequentially taken out, and a predetermined reference value is set for each of these data in accordance with a processing program for an analysis algorithm preset for each system. An analysis is performed using the analysis results, and a display condition of a display size, a resolution, and a display position to be displayed this time is derived according to the analysis result, and a process of issuing a correction command is performed (Steps St31 to St40).
[0040]
As a result, as shown in FIG. 8, the signal creation and transmission function 24a converts the transmitted correction command into a signal corresponding to the characteristics of the display control device 30 and transmits the signal to the display control device 30. If this transmission is not successful, the same process is repeated again (Steps St41 and St42).
[0041]
In this example, as the reference values used in the analysis algorithm to be executed by the analysis & optimum value generation function 23a, in this example, any data of the electroencephalogram system, the respiratory system, and the blood system are initially stored in the measurement value storage DB 22b. The default value set in advance according to the gender, age, etc. of the user OP who is the sender is stored in the measured value storage DB 22b after a certain period of time (for example, several minutes) has elapsed thereafter. A set value set for each caller based on a statistical value such as a mode (mode) of a measured value is adopted.
[0042]
Here, if the measurement data belongs to an electroencephalogram system such as an electroencephalogram, an electroencephalogram analysis algorithm is executed. As an analysis algorithm for this electroencephalogram system, for example, measurement values are added based on the reference values of α waves and β waves (initial default values, and thereafter, after a certain period of time, set values based on accumulated data) and taking into account the error. Are within the preset range of appropriate values (for example, upper limit of appropriate value = reference value + reference value × several% ÷ 200, lower limit of appropriate value = reference value−reference value × several% ÷ 200) In other words, a method of analyzing whether or not an increase or a decrease (change) by more than a predetermined percentage (%) width from the reference value is adopted.
[0043]
As a result, if the measured value is within the range of the appropriate value (if there is no change), the current display size, resolution, and display position are maintained (not changed), and the measured value is out of the range of the appropriate value. If there is a fluctuation, a correction command is generated to change the current display size, resolution, and display position according to a predetermined reference pattern, and the correction command is generated and transmitted until the measured value returns to a proper value range. The processing to be output to the display control device 30 via the function 24a is repeatedly executed.
[0044]
As the reference pattern, a pattern that is considered to be optimal according to the gender and age of the user OP is used as a default value at the beginning, and after a lapse of a predetermined time (for example, several minutes), the measured value accumulation DB 22b is used. A pattern that can be set for each caller is adopted as a set value based on the measurement data accumulated above, the current display conditions, and the like.
[0045]
As an example of the default value, for example, when the measured value is larger (or smaller) than the upper limit (or lower limit) of the appropriate value range, the display size is increased (or reduced) by a predetermined amount. The display position is increased by a predetermined amount (or lowered) by a predetermined amount, and the display position is moved by a predetermined distance in a predetermined direction (for example, up, down, right, left direction) (or a preset center side area, upper area, lower area, left area) , Right side area, upper left area, lower left area, upper right area, lower right area, etc.).
[0046]
In addition, the resolution, display size, or display position to be changed first is initially determined by the default value, and after a few minutes elapse, the characteristics and flow rate of the person (vital capacity x respiratory rate / specified time) are determined It is preferable to change the order of changing the resolution, the display size, and the display position for each sender.
[0047]
In the above processing, if the measured value does not return within the proper value range (several%) even if the correction command is issued for the preset specified number of times, the appropriate value range (percentage width) and the specified number of correction command The set value is changed, for example, the percentage width is increased by 1% and the specified number of times is increased by 10%, and thereafter the same processing is repeatedly executed.
[0048]
The above analysis algorithm is for the case of the electroencephalogram system, but is the same for the case of the respiratory system and the blood system. For example, in the analysis algorithm for the respiratory system, measured values such as, for example, the number of breaths and the flow rate (volume of breathing x the number of breaths / specified time), and in the analysis algorithm for the blood system, the measured values such as the pulse count and the blood pressure value, The analysis is performed based on a reference value (a default value at first, and a set value for each caller after a lapse of a predetermined time). That is, in the case of the respiratory system and the blood system (pulse, blood pressure), the measurement data is analyzed in the same manner as in the case of the electroencephalogram system according to the respective analysis algorithms, and a correction command for changing the display condition is generated according to the analysis result. And transmitted to the display control device 30 via the transmission function 24a.
[0049]
In the above processing, if a correlation can be found among the data of the brain wave system, the respiratory system, and the blood system, a correction command may be issued in consideration of the correlation coefficient obtained between the data. Regarding the processing priority of which data of the electroencephalogram system, the respiratory system and the blood system are to be processed with priority, the default value is initially checked and the priority order is determined each time a predetermined time (for example, 15 minutes) elapses. It is preferable to review The review time interval in this case is also extended by a predetermined time (for example, one minute) if the number of times the instruction is issued is smaller than the default value. Conversely, when the number is large, the predetermined time (for example, one minute) is shortened (however, the minimum time interval is set to, for example, two minutes). Also, the width is not fixedly set from the beginning, but is adjusted to the state at that time.
[0050]
Therefore, according to the present embodiment, it is possible to set the optimal display size, resolution, and display position for each person based on the biological unique information constantly or periodically measured from the user OP, Characters and images can always be displayed under optimum display conditions in accordance with the work progress status and the accompanying biological fatigue status for each user, and the load on the living body can be greatly reduced.
[0051]
In addition, as other examples of the analysis algorithm, measured values accumulated so far, characteristics recognizable for each sender (for example, statistical values such as modes), and results obtained in the past (measured values and (Correlation with display conditions, etc.), EEG / personal characteristic coefficients for EEG-based measurement data, and respiration rate and flow rate (Vital capacity × respiration rate / specified time) for respiration-based measurement data. ) / Coefficients of personal characteristics, if it is blood measurement data, reference values / coefficients of personal characteristics are obtained, these coefficients are written in the measurement value accumulation DB, and the display size to be displayed this time on the display control device; It is also possible to configure to send as resolution and image display value.
[0052]
Further, as another configuration example of the analysis & optimum value generation device, the receiving unit may be configured to receive a signal regardless of wired or wireless, and the transmitting unit may generate a signal regardless of wired or wireless. The storage means may apply a storage medium for storing regardless of capacity and form.

The format may be determined, and the storage device function may be configured to recognize the internal and external storage media by initial setting and determine the storage mode.
[0054]
