Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for measuring human motion, behavioral state, and physiological state, and detecting, predicting, and reporting abnormal states of human body motion and behavior from the measured information.

[0002]

2. Description of the Related Art In recent years, nursing care for the elderly has attracted attention in the context of the advent of an aging society. In particular, nursing care for patients with dementia and elderly people with wandering is very important, and various techniques have been proposed. It is considered that the means of tracking the behavior of these elderly people and notifying the person or the outside when abnormal behavior is performed is very effective from the viewpoint of nursing care. Also, if we can measure and analyze not only elderly people but also human behavior, for example, we can obtain behavior patterns,
Lighting and air conditioning can be controlled comfortably and operated safely, which is very effective for human life.

[0003] Furthermore, it is effective to measure behavior and the like not only in humans but also in animals and machines. In the case of animals, it is possible to use them for research on ecology that was unknown until now. If the operation can be measured, it can be operated efficiently and safely, which is very effective from the viewpoint of production activities and the like.

[0004] By the way, in grasping the behavior of a human body or an object, it is very important to grasp "who (what)", "where" and "what". For that purpose, it is necessary to identify an individual or a specific object, detect a position in a room, and detect an operation or a posture.

A method for identifying an individual or a specific object is RF-I.
D or a method based on image recognition from a CCD image. RF-ID is a tag attached to a mobile object such as a human body or an object (also referred to as a transponder; hereinafter, unified as a tag).
An antenna connected to a processing device such as a computer (also referred to as a reader; hereinafter, unified as an antenna)
Is a system that receives a radio wave of a specific frequency and automatically identifies an object.

This system can be roughly classified into two types according to the tag reading distance. One is a short distance type using low frequency, and the reading distance between the tag and the antenna is 50c.
m or less. In these cases, the tag is generally held over an antenna or the tag is sewn to the end of the pants and read by an antenna installed on the floor. The other is a long-distance type using microwaves, in which the reading distance between the tag and the antenna exceeds 1 m. By carrying them on a part of a body or a part of an object, they can read tag information without being conscious when passing near an antenna.

A method based on image recognition from a CCD image is as follows.
Photographing the human body or object passing through the entrance of a room or the like with a CCD camera, extracting features such as the face of the human body or the shape or mark of the object by image recognition, and collating it with unique features registered in advance. Is used to identify an individual or a specific object.

Methods for specifying the position of a human body or an object in a room include extraction from a CCD image and extraction from temperature distribution information obtained by a two-dimensional infrared sensor.
In addition, there has been proposed a method of specifying an approximate position from the intensity of radio waves from a plurality of base stations using a PHS or the like in a very large building.

As a method of detecting an operation or a posture, a method of discriminating a stationary state and an operation state using a pedometer (registered trademark), a mercury switch, or the like has been proposed in the past. Recently, various acceleration sensors and gyro sensors (angular acceleration sensors)
Have improved performance, and using them, the walking state, body tilt,
A method of detecting a walking direction or the like has been proposed.

[0010]

As described above, various methods have been proposed for the purpose of detecting "who (what)", "where" and "what". Can only satisfy a single function. In other words, it is not possible to comprehensively determine “who (what)”, “where” and “what”.

[0011] The RF-ID can identify a specific individual or object entering the room, but when a plurality of people enter the room,
Even if a method of specifying the position of a human body or an object is used, it is impossible to determine “who (what)” or “where”. Further, even if the posture can be detected using the acceleration sensor, for example, it is impossible to determine at which position the posture is being taken.

There are also some problems in the above-mentioned method. In the RF-ID mentioned as a method for identifying an individual or a specific object, the short-distance type needs to intentionally hold the tag over the antenna because the communication distance between the tag and the antenna is short. On the other hand, since the long distance type has a long communication distance between the tag and the antenna, it may not be recognized only when passing through an entrance such as a room, but may be recognized only by passing by the antenna without entering the room. is there. CCD
In the method of identifying an individual or an object from an image, it is necessary to extract a feature amount from the image. Therefore, for example, when a face is not visible in a shield or at night, no human body can be detected.

Therefore, for example, by accurately capturing the entry and exit of a human body into a room in a house, and at that time, after identifying the individual, the position, posture, behavior, and the like of the human body are detected. A system has been proposed in which the above-mentioned "who,""where," and "what" are being performed in a complex and accurate manner.

However, in such a system, it is possible to accurately obtain the behavioral state of "who", "where" and "what". For example, the home of the person whose behavioral state is to be detected and the hospital are separated from each other. In the past, a doctor at a hospital could not automatically know the behavior of the detection target person. Therefore, when there is an abnormality in the detection target person or when there is a possibility that an abnormality may occur, the doctor should immediately give some advice such as giving coping information to the detection target person or its assistant. Could not.

In view of the above-mentioned problems, the present invention automatically transmits information on the activity state of a detection target person to a first Internet terminal of a predetermined manager (for example, a doctor) via the Internet, Provided is a behavior detection system that enables information exchange between a detection target person or an assistant thereof and a manager by using a second Internet terminal that bidirectionally communicates with the first Internet terminal via the Internet. The purpose is to:

It can be managed collectively, the behavior of the human body in the whole building can be grasped in real time, and it has the effect that countless applications such as abnormality detection, control of air conditioning and lighting, and security are possible.

As described above, specifying the human body, specifying the position of the human body, specifying the posture, action, activity state, and physiological state of the human body, and integrating the behavioral information and physiological information of those individuals By comparing / evaluating with the daily behavior / physiological state, and determining the abnormal state of the behavior, the abnormal state can be reported, the abnormal state can be eliminated, and a safe, secure and comfortable environment can be created. . Therefore, by using the abnormal behavior detection system of the present invention, it is possible to easily and highly accurately detect and predict abnormal behavior with high reliability at low cost, which can greatly contribute to the expansion of the HII business. .
