Description

Mobile communication terminal providing personalized biorhythm information and method of providing the information {MOBILE FOR PROVIDING PERSONALLY ADUSTED BIORHYTHM INFORMATION, AND THEREOF METHOD}

The present invention relates to a mobile communication terminal for providing biorhythm information and a method of providing the same, and more particularly, it is possible to easily measure and input the status information of the current user, and to use it more accurately and usefully. A mobile communication terminal capable of providing information and a method of providing the same.

Biorhythm is the theory that there are three cycles of body, emotion and intelligence in the human body, and these cycles appear in a specific pattern according to the date of birth, and the combination of these patterns differs in ability or activity efficiency. It is called the biological cycle or commonly called a biological clock or an internal clock. The physical (23) period is 23 days, emotional (28 days), and the intelligence (Intellectual) has a 33-day cycle, showing a change in the rising or falling. In the nineteenth century, Wilhelm Fleece, an otolaryngologist, studied the development of fever, claiming that there were 23 and 28-day cycles in the human body, and then developed by Alfred Teller to study his students and insist on the 33-day cycle of intelligence.

The body rhythm is a rhythm representing the physical state of the body and is used as a measure of immunity against disease, the functions of various internal organs, and the body's reflexes to the external environment. Emotional rhythms are rhythms that describe mood or the state of the nervous system, indicating creativity, interpersonal relationships, and ups and downs. Intellectual rhythm is a rhythm that represents the ups and downs of concentration, memorization memory, logical thinking, analytical discrimination, and is mainly related to brain activity. Each of the three biorhythms is represented by a sine curve with a certain period. The date of birth determines the indices of body, emotion and intelligence. Biorhythm, which numerically expresses the rhythm of the human body, is actively used to prevent the occurrence of industrial accidents not only in individual daily life but also in industrial sites.

Currently widely used biorhythms predict body, emotion and intelligence based on date of birth. That is, it is assumed that everyone born on the same day has the same biorhythm. However, since the individual's biorhythm is greatly influenced by factors such as the environment in which the individual grows and lives, it is difficult to determine the individual's biorhythm by only the date of birth. Indeed, biorhythms, calculated on the date of birth, often do not match the current status of 'I'.

For example, even when the physical condition is peaking, the calculated biorhythms sometimes come out poorly. Therefore, in order to actively use biorhythms in daily life and industrial sites, it is necessary to supplement the existing biorhythm calculation methods that depend only on the date of birth, and to calculate the personalized bi-orithms that can more accurately express the current state of the individual. Method is required.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The three biorhythms of body, emotion, and intelligence each have a characteristic that is represented by a sinusoidal curve with a certain period. Accordingly, embodiments of the present invention measure and measure state information (body, intelligence, sensitivity) of an individual based on the characteristics of the biorhythm in order to tune the biorhythm to best match the current state of the individual and to calculate more accurate predictions. The present invention has been made to provide an apparatus and method which can be conveniently provided by a mobile communication terminal by inputting and estimating or correcting parameters of a biorhythm model.

1 is a diagram illustrating a configuration of a mobile communication terminal that provides personalized biorhythm information through parameter estimation according to an embodiment of the present invention.

As shown in FIG. 1, the mobile communication terminal according to the present invention includes a state measuring unit 10 for measuring a body index, an intelligence index, and an emotional index in a common configuration (not shown) of a power supply unit, an input unit, a calculation unit, and a display unit, The biorhythm model unit 20 includes a biorhythm system 100 including a model parameter estimator 30 and a linearizer 40.

Here, the state measuring unit 10 is configured to include a sensor capable of measuring the state of one's body, emotion, and intelligence from the user, and an analyzer for analyzing and converting the data measured by the sensor into numerical information.

2 is a diagram illustrating an application example of a mobile communication terminal applied to measurement of body index information of a user according to an embodiment of the present invention. The body rhythm is a rhythm representing the physical state of the body and is used as a measure of immunity against disease, the functions of various internal organs, and the body's reflexes to the external environment.

Electrocardiogram (EKG) data can be used as data to measure body rhythm or body index. Electrical activity is produced by the heart cells when ions are exchanged across the cell membrane, and the electrical energy detected by connecting the electrodes that can conduct electrical activity from the heart to the electrocardiogram to the limbs and anterior thoracic is shown in the graph shown on the electrocardiogram. This is called an electrocardiogram (EKG).

The electrocardiogram (EKG) data is widely used to diagnose various diseases such as heart disease, myocardial infarction and anemia. Therefore, electrocardiogram (EKG) data can be a very important indicator for specifying the physical rhythm of the individual, so the data collected from each hospital is collected and converted into body index to the body index. Can be obtained.

By using this principle, the present invention, as shown in Figure 2, by measuring the electrocardiogram (EKG) data through a measurement sensor mounted on the mobile communication terminal, and includes an analysis unit for analyzing the measured data to convert into body index information The state measuring unit 10 is configured in the biorhythm system. The measuring sensor extracts the measuring pad from the mobile communication terminal and fixes it in the vicinity of the heart or a specific part of the limb and measures the EKG for a certain time.

The ECG data is analyzed again by the analysis unit, converted into body index information, and extracted as biorhythm information. As described above, the present invention includes a simple measuring sensor in a system equipped with a high performance portable processing device such as a mobile communication terminal, so that the body index can be measured more accurately and simply.

In addition, the body index may be used not only to the above-described electrocardiogram (EKG) data, but also to measure and balance the individual user's sense of balance using a motion sensor mounted in the mobile communication terminal and convert the body index into numerical figures. Not)

For example, if the user is holding the terminal and raising one foot, standing for a certain period of time, in normal and good condition, there is little shaking, so the output of the motion sensor that captures a specific movement is small, but in abnormal condition, the sense of balance is poor. It will fall off, so you won't be able to stand on one foot for a long time, so the output will be high on the motion sensor in a short time.

As described above, the mobile communication terminal according to the present invention can standardize the data measured by the measurement sensor in the analysis unit and input the body index into the biorhythm model unit. In addition, various sensors may be mounted on the terminal to measure the body index of the user using various data (sweat, temperature, etc.) of the human body.

3 is a view showing a display window showing an example of measuring the intelligence index in the mobile communication terminal according to the present invention. Intellectual rhythm is a rhythm representing the ups and downs of concentration, memorization memory, logical thinking, analytical discrimination, etc. It is a rhythm mainly related to brain activity, and the index indicating this is the intelligence quotient (IQ).

As shown in FIG. 3, the intelligence index is measured and provided to the display window through a program embedded in the mobile communication terminal, and the user evaluates and indexes the intelligence state through the response. As such, it is also possible to measure the intelligence index in the form of a problem, but it is also possible to provide a variety of brain games, and to measure the intelligence index by indexing the user's game performance ability.

4 is a view showing a display window showing an example of measuring the emotional index in the mobile communication terminal according to the present invention. Emotional rhythm is a rhythm indicating the state of mood or nervous system, indicating creativity, interpersonal relationship, ups and downs of emotions, and the index indicating this is the emotional index (EQ: Emotional Quotient).

Emotional indices first appeared in 1990 by Salovey & Mayer and the term was used for the first time, and emotion evaluation / expression, emotion control, and emotional use for problem solving were the three components of EQ. Emotional evaluation / expression involves evaluating and expressing one's feelings and evaluation of others' feelings, and subdividing them into verbal and nonverbal perceptions. Emotional control also includes controlling one's feelings and the feelings of others. Emotional use includes elements such as resilient planning, creative thinking, attention shifting, and motivation.

As such, the emotional index (EQ) can be evaluated using the evaluation measurement tool items reported in the literature. In the present invention, as shown in FIG. 3, the emotional index of the user is provided through the emotional index evaluation item provided by the terminal. You can measure it. For individuals, the basic sentiment index appears in their own personality, but the evaluation index may change every time due to emotional ups and downs due to changes in the surrounding environment. Therefore, in the present invention, it is possible to measure the emotion index of the current individual more accurately and conveniently through the evaluation items provided in the classified and statistical terminal.

As described above, the present invention accurately measures the state information of the individual's body, intelligence, and emotion with a measuring device mounted in the terminal, estimates parameters of the biorhythm model based on the data, and facilitates more accurate biorhythm information. It is intended to propose a mobile communication terminal and a method of providing the same.

Hereinafter, a method of calculating a personalized biorhythm system through parameter estimation will be described with reference to FIG. 2.

When the state measuring unit 10 of the mobile communication terminal measures the state of the user's body, emotion, and intelligence as numerical information (S100), the model parameter estimator 30 uses the Newton-Lapson method to create a biorhythm model. The parameter 20 estimates a parameter representing parallel movement between the period and the time axis. (S110) The parameter estimated from the model parameter estimator 30 is input to the biorhythm model unit 20. (S120) )

The biorhythm model unit 20 calculates and predicts the user's biorhythm using the estimated and input parameters (S130).

When the user further measures and inputs state information of the body, emotion, and intelligence (S140), the model parameter estimator 30 is linearized from the linearizer 40 and inputs the linear biorhythm model and the newly input state information. By using the above, the parameters of the biorhythm model that were last estimated and input to the biorhythm model unit 20 are corrected. In this case, the model parameter estimator 30 uses a cyclic least square method for parameter correction. The corrected parameter is input to the biorhythm model unit 20 (S160), the biorhythm is calculated and predicted (S170), and displayed on the display unit of the mobile communication terminal (S180).

Here, as described above, the measurement and input step of the body, emotion and intelligence index (S100, S140), it is also preferable to measure the body index through the sensor mounted on the terminal, and through the evaluation questions provided by the terminal It is also desirable to measure the sensitivity index.

In addition, other parameter estimation methods such as a maximum descent method may be used. In addition, since the response of the biorhythm model appears as a vibration and its characteristics are clear, the parameter may be estimated by wavelength analysis through Discrete Fourier Transformation.

Meanwhile, in the exemplary embodiment of the present invention, the biorhythm model of the body, emotion, and intelligence is represented by a sinusoidal curve, but in addition to the cosine curve, the biorhythm model may be represented by curves having a constant period. In the exemplary embodiment of the present invention, the oblivion index is expressed as Equation 3, but it may be expressed by another form of applying a small weight to past information data. In addition, in the embodiment of the present invention, the cyclic least square method is used in the step of correcting a parameter by using newly input state information of body, emotion, and intelligence, but other state estimator including a Kalman filter may be used. have.

In the embodiment of the present invention, the parameter is estimated using all the body, emotion, and intelligence state information measured and input by the user, but in order to reduce the amount of calculation, the old data of the past is deleted to reduce the number of data used when estimating the parameter. How to keep it constant, enter a set of predefined integers into the variables that represent the parallel movement to the period and time axis, which are parameters to be estimated, and among them, the parameter that minimizes the objective function value in [Equation 2] The method of selection is possible.

Meanwhile, the embodiments of the present invention described above are not only implemented through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. However, such an implementation can be easily implemented by those skilled in the art from the description of the above-described embodiments.
