Description

SYSTEM FOR TUI WHICH RECOGNIZES INFORMATION OF A LIVING BODY AND A CHIP USED THEREFOR}

The present invention relates to a device capable of determining human emotion, comprising: a system for accepting an emotional index for each bioinformation factor, performing signal processing for each factor, analyzing correlations, and determining human emotion, such as white heart joy; It relates to a biochip used therefor.

That is, the present invention quantifies the emotion of the joy and electromagnetic quantitative to be applied to a variety of electronic and information devices for this purpose, and to detect the signals of electrical conductivity, pulse, body temperature, etc. among the biological signals of the human body through the filter One chip type ASIC device invented to condense all functions into one integrated circuit to format a signal, process correlation between each biosignal and human emotion, and output the result to the outside.

Looking at the development stage of the interface, starting from the existing DOS operating system (CUI) (Capital User Interface), through the Windows operating system Graphical User Interface (GUI) into the age of HCI (Human Computer Interface), now TUI (Tangible) User Interface) is being discussed.

Looking at the related technologies of TUI, the development of sensors that can accurately measure the bio-signal has been completed, but the problem of measuring and modeling the bio-signals for many people due to the characteristics of the living body is still an unsolved problem. Remains as.

On the other hand, programs for predicting various situations using the measured data due to the development of computational technology such as economic forecasting and agricultural production forecasting are surprisingly developed. Therefore, if the data obtained by measuring in the living body can be obtained more accurately, it will be possible to program and develop a TUI that can adapt to the numerous changes that the living body exhibits by the change of emotion.

Another problem with TUI's technology is that even if it succeeds in making formal logic using bio signals, it is too difficult to apply it to mental changes such as emotions. It is the reality that it is only used for a limited amount, such as to identify diseases.

This can be guessed by considering that the biological characteristics are changed by a number of variables. In other words, there are limitations in the existing research approach of sampling a large population, obtaining a large number of cases, deriving average values and deviations, and applying generalized logic to mental situations.

The biggest problem with the traditional approach is that it is in sampling and processing of measured values. That is, problems in obtaining statistically meaningful values from a sample, problems in establishing an estimated flexibility relationship through measured statistical values, and mental steps of statistically deduced numerical values from biological signals. In order to solve various problems, such as a problem in switching, a living body should approach in consideration of the fact that it generates various biological signals but always has a threshold.

Therefore, statistics such as the change of direction in sampling, the application of various statistical techniques to find out the statistical flexibilities, and the quantification of mental changes by contrasting the mental relations with the flexible relations divided into several stages. It is necessary to change the concept of the treatment.

In view of the above points, the present inventors extract five healthy men and women, each of whom can clearly express the emotion of happiness, and measure and signal in consideration of somatic movement, pulse, GSR, skin temperature, blood pressure, etc. The treatment was performed.

In the academic world, HCI laboratories are mainly focusing on developing technologies to improve the existing operating system in terms of ergonomics. In the industry, visual and voice interfaces are studied. We are working on the field of HCI fusion technology.

There is a bar. The contents of this application are incorporated herein. Biopia Co., Ltd. has developed a TUI using pulse and skin conductivity and commercialized it in 2000 by applying it to an emotional mouse.

However, the present invention relates to a simple medical examination product by grasping a user's tension using a GSR, etc., among various various methods for measuring a bio-signal, and indicating a current state of health, but a mouse currently used for this purpose, Products such as mouse pads are mostly PC-based and are almost useless without a PC.

Biological information can identify mental stability states individually, but there is insufficient information to grasp specific emotional states such as hee, noh, lament, and rock. For example, in the case of GSR signals, resistance tends to increase in steady state and decrease in psychological anxiety. There is an example of using this to use a lie detector, etc., but in order to determine the specific emotional state, it is necessary to apply the interaction of the biometric information as the basis of the judgment.
