System and method for providing nutrition and / or health information.

With the development of computer technology and information and communication technology, the distribution of information using computer networks such as the Internet is increasing rapidly. Such information may include information relating to health or diet, in particular health or diet information for the distribution of exercise or diet-related information (herein referred to as 'diet information') for weight loss. Many sites have appeared. Since the distribution of information through the Internet is carried out beyond space, there is an advantage that the information provider and the information user are not limited by physical time and space.

However, since information for an individual's health or diet should vary according to an individual's physical characteristics or biometric characteristics, an information user who wants to use health or diet information should provide accurate data on his or her physical characteristics or biometric characteristics. There is a need. However, in the Internet environment where the information provider and the information user are physically separated, it is very difficult to accurately provide the physical information and the biometric information of the information user.

Meanwhile, the telemedicine system disclosed in Japanese Patent Publication No. 1999-017304 published on March 15, 1999 basically uses a subscriber identification module (SIM), and medical information analysis means for analyzing secretions of information users. And means for transmitting and receiving home medical information for transmitting and receiving the analyzed data. The subscriber identification module (SIM) used in the conventional telemedicine system refers to a kind of information terminal that can be carried by an individual while allowing all data processing processes for a mobile phone service to be based on strong security functions such as password and authentication. However, this conventional telemedicine system has the disadvantage of requiring expensive analysis equipment separately from the user, and it is difficult to provide nutrition information and / or health information to the user.

Therefore, it is required to provide appropriate health information and diet information to each individual by using a communication terminal which can be always carried by the information user and taking into account the physical information and the ecological information of each information user.

Accordingly, an object of the present invention is to provide a system and method for providing health information or diet information to a user based on a result of receiving the user's body information or biometric information through a portable communication terminal and analyzing the result.

Another object of the present invention is to provide nutrition information and / or health information that is most suitable for a specific individual by reflecting the differences according to individual information users.

Another object of the present invention is to increase information accessibility of information users.

The web operates in the form of a fully distributed server / client model, and can provide information in various forms such as graphics, audio, and video using the client's multimedia environment.

The proxy server 43 translates the request of the portable communication terminal 12 into a web request and submits it to the web server 42, and transmits the response of the web server 42 to the portable communication terminal 12, for example, binary data. Encode with. On the other hand, if the web server 42 provides wireless content (eg, WAP content such as Wireless Markup Language (WML)), the proxy server 43 can retrieve it directly from the web server 42. However, if the web server provides web content such as HyperText Markup Language (HTML), a separate filter (eg, an HTML filter, not shown) is used to convert the web content into WAP content.

The web server 42 includes means 45 for analyzing the biometric data transmitted from the portable communication terminal 12, and means 46 for determining the physical state of the information user based on the analysis result and the body information of the information user. And means 47 for calculating nutrition and / or exercise prescription data according to the body state determination result.

Of course, the biometric information analysis result data and the prescription data may be provided to the information user through the web server 42.

2 shows an information flow according to an information providing method according to the present invention. The information user inputs his or her body information using the portable communication terminal (step 51). Physical information includes height, weight, age, gender, activity index, and the like. The user measures biometric information using the portable communication terminal (step 52). As described later, the biometric information measurement may be performed by the body fat measurement module and the heart rate measurement module attached to the portable communication terminal. On the other hand, the measurement result of the biometric information can be displayed on the portable communication terminal so that the user can confirm the result.

The portable communication terminal transmits a content request to a server system, for example, the information providing system according to the present invention, and the server receives and processes it (step 53). Such request reception and processing includes a process of translating data transmitted from the wireless communication terminal into, for example, a web request to fit the server system. The server system receives the biometric data and the body information data (step 54).

In operation 55, the server system analyzes the biometric information data. For example, the biometric data analysis result data may include the standard user's standard weight obtained based on the body fat and the body information data of the user included in the biometric data. The biometric information analysis result may include resting heart rate, heart rate during exercise, and target heart rate range data based on the heart rate measurement. This result can be periodically transmitted to the portable communication terminal. Biometric data may be used in the nutrition and / or exercise prescription procedure 70.

If the remote connection is determined, the information providing system 40 is accessed through a predetermined login procedure (step 62). Remote access includes wireless connection using a portable communication terminal and wired connection using a computer system. In the information providing system 40, a nutrition and / or exercise prescription procedure (step 70) is performed, which will be described later with reference to FIG. Prescription result data may be periodically transmitted to the portable communication terminal in step 64.

3 is a block diagram showing a schematic configuration of a portable communication terminal having a biometric characteristic measurement function according to the present invention.

The portable communication terminal 12 has a structure in which the biometric information measuring module 120 is integrated into, for example, a personal communication service (PCS) phone or a cellular phone. The biometric information measuring module 120 may be configured in one piece or in a separate type. The CPU 108 of the portable communication terminal 12 controls the operations of the transmitter 102, the receiver 104, the modem 105, and the memory 106. Each component of the portable communication terminal is supplied with energy by the power source 116. The wireless signal is transmitted and received through the transmitter 102, the receiver 104, and the antenna 114.

The keypad 112 is a user interface for wireless communication and user's body information input and may include a scroll button, a numeric pad, and the like. The display 110 includes, for example, an LCD screen, and displays numbers, letters, or graphics of data input by a user. The data displayed on the display 10 may include a user's body information and biometric information measurement results. Display 10 may also display guide data that describes how a user measures biometric information. This guide data is stored in the memory 106.

According to an embodiment of the present invention, the biometric information measuring module 120 includes a body fat measuring unit 122 and a heart rate measuring unit 124 having the structure shown in FIGS. 4 and 5.

4 is a view for explaining a body fat measurement process using a portable communication terminal according to an embodiment of the present invention.

In general, methods for measuring body fat include an underwater measurement method, potassium method, gas diffusion method, DEXA method and the like. Underwater measurement measures the body fat using the average specific gravity of the human body by submerging in water and weighing in and out of the water, and the potassium method measures the amount of potassium in the whole body, It is a method of inverting the amount of fat by estimating the amount of tissue, and the gas diffusion method sends the subject into a box of a constant capacity containing a gas that is harmless to the human body, and the concentration of gas in the box increases according to the change. It's a way to measure a person's volume. DEXA method is a method of using the human body bone inflammation (bone mass) using a small amount of X-rays. However, such a method requires a very high level of skill, requires complicated operation using an expensive apparatus, and takes a long time to measure, thereby causing a problem in practicality.

On the other hand, a more convenient body fat measurement method is a sebaceous method that calculates the body fat percentage according to its thickness by picking up the upper arm and the lower scapula into the gingival fat method, and an ultrasonic method that calculates the body fat percentage by measuring the thickness of two points with ultrasound. There is a near-infrared method which measures near-infrared rays on the upper back muscles and measures the reflected light of fat, analyzes the spectrum, and measures body fat. However, this method assumes an even distribution of the muscles of the human body and has a disadvantage in that the deviation is large depending on the measurer.

In an embodiment of the present invention, body fat is measured by using the impedance method. Body fat measurement by impedance method is characterized by simple measuring device, safe and short measuring time over a wide range of objects, and no special technique or procedure for measuring. Impedance method uses the principle that the electrical conductivity in the body is proportional to the amount of water and electrolyte in the body. Restricted tissues (fat-free tissues) contain a lot of water (72% to 73% including electrolyte) and are easy to conduct electricity. However, since adipose tissue contains little moisture, the tissue itself is insulated and does not carry electricity. The impedance method is to measure the electrical resistance in the body and derive the body fat percentage using this principle. The partial method calculates the fat percentage of the entire body by measuring from the soles and soles of the body, that is, part of the body, the back of the hand without the stratum corneum, The improved partial method for calculating fat percentage by partial measurement on the back of the hand, and the systemic method for measuring on the back of the hand and foot.

Body fat measurement unit 122 according to an embodiment of the present invention shown in Figure 4 applies a high frequency constant current generated in the high frequency constant current circuit 126 to the human body of the user through an electrode (not shown). The high frequency constant current circuit 126 may include, for example, a fixed voltage oscillator generating a 50 sine wave and a voltage / current converter converting it to a constant current of, for example, 800 kHz. The electrode to which the high frequency constant current is applied is attached to, for example, a main body (not shown) of the portable communication terminal 12 and is in close contact with a body part of the subject 130 (user).

The voltage value detected through another electrode (not shown) in close contact with the body of the subject is amplified by the amplifier 132, for example, a differential amplifier, and rectified by the rectifier 134. The rectifier 134 includes a filter such as a low pass filter (LPF), and may waveform-shape the rectified signal. The output of the rectifier 134 is amplified once more in the main amplifier 136 and then converted into a digital signal by the AD converter 140 and input to the CPU 108.

The CPU 108 uses the current value I applied by the high frequency constant current circuit 126 and the voltage value V detected by the subject 130 to determine the electrical impedance of the subject 130 (Z = V / I). Calculate The CPU 108 calculates the body fat amount of the subject by using body information (height and weight) data of the subject 130 input through the keypad 112 and the calculated electrical impedance of the subject. The calculation of the body fat amount is based on the calculation result of the body density, and the body specific gravity (BD) can be obtained as shown in Equation 1 below.

Body specific gravity (BD) = C-K`W / Z / H ² + K`` · Z (Equation 1)

(Where C is a constant, K`, K, is a proportional factor, W is weight, Z is impedance, H is height)

In Equation 1, the coefficients K` and K`` are obtained statistically by experiment, and the K`` · Z term is a term for correcting the effect of the impedance change on the body specific gravity.

Body fat can be calculated by, for example, the following formula (2).

Body fat (%) = (4.57 / BD-4.142) 100 (Equation 2)

The body fat calculated by the CPU 108 is displayed on the screen via the display 110 and transmitted through the transmitting unit 102 of the portable communication terminal 12.

5 is a view for explaining a heart rate measurement process using a mobile communication terminal according to an embodiment of the present invention. In FIG. 5, the heart rate measuring module 124 includes a voltage measuring unit 128, an amplifier 150, a pulse shaper 152, and a pulse counter 154.

When an electrode (not shown) of the voltage measuring unit 128 attached to the main body of the portable communication terminal is brought into close contact with a body part of the subject 130, for example, the right hand and the left hand, the voltage due to the heartbeat of the subject 130 A change can be obtained. This voltage variation is amplified by an amplifier, for example differential amplifier 150. The amplified voltage change signal is converted into a pulse signal by the pulse shaper 152. The pulse signal is counted in pulse counter 154 to obtain a heart rate. The output signal of the pulse counter 154 is input to the CPU 108 as a digital signal. The pulse counter 154 may be configured as a separate circuit or may be configured as part of a circuit integrated in the CPU 108.

The CPU 108 displays the calculated heart rate on the display 110 and transmits the same through the transmitter 102. In this embodiment, the electrode of the voltage measuring unit 128 is the same electrode as the voltage measuring electrode used in the body fat measuring process described with reference to FIG. 4. In this case, the heart rate measurement module is stopped while the body fat measurement module is in operation, and the body fat measurement module is controlled by the CPU 108 so that the operation is stopped while the heart rate measurement module is in operation.

6 is a block diagram showing a configuration according to another embodiment of the heart rate measuring module according to the present invention. The same reference numerals are used for the same components as those in FIG. 5 and detailed descriptions thereof will be omitted. The heart rate measurement module 129 of FIG. 6 uses a pressure sense 160. The pressure sensor 160 detects a pulse according to the heartbeat of the subject 130 and converts the pulse into an electrical pulse. The converted pulse signal is calculated by the pulse counter 162 and input to the CPU 108 as a digital signal. This embodiment is advantageous in that it is portable because only one sense needs to be used instead of two or more separate electrodes.

7 is a flow diagram illustrating a nutrition and / or exercise prescription procedure in accordance with the present invention. This procedure may be provided via a web page.

The remotely connected user enters additional information (step 71). Additional information may include e-mail addresses, marital status, eating habits or lifestyles, diet history, and may include entering a member ID and password.

Body weight data transmitted through the mobile communication terminal 12 is used to obtain a standard weight and to evaluate obesity. The obesity evaluation step 72 may use the result of the bioinformation data analysis step 55 of FIG. 2 as it is. The standard body weight is obtained by "standard body weight [kg] = lean body mass / (1-or more body fat)", and the lean body mass is calculated by "fat-free mass [kg] = body weight (1-body fat)". Obesity is obtained by "obesity = current weight-standard weight". Obesity evaluation in step 72 may be the result of comparing the obesity value and zero. That is, it is evaluated as "dry" when the obesity value is less than 0, "standard" when the obesity value is equal to 0, and "obesity" when the obesity value is greater than 0.

However, the evaluation of the degree of obesity is not limited to the above three, detailed evaluation based on body fat, sex, age, etc. is also possible. For example, obesity may be evaluated based on the following [Table 1], [Table 2] and body fat (%).

The choice of prescription type also takes into account the weight (desired weight) data desired by the user. The prescription type is divided into a nutrition prescription menu 74, an exercise prescription menu 75, and a nutrition / exercise prescription menu 76.

The nutrition prescription menu 74 calculates and presents a daily recommended nutritional calorie based on the user's personal information (physical information, biometric information and additional information) and selects a desired diet from the recommended calorie diet. Step 78 and step 79 of calculating and displaying the nutritional prescription result. Recommended nutritional calories are calculated from less calories than are currently needed to maintain weight. The diet selection step 78 can be omitted.
