METHOD OF OBSERVING WALKING OF AGED PERSON AND WALKING OBSERVING DEVICE FOR AGED PERSON

摘要

PROBLEM TO BE SOLVED: To early and precisely grasp the abnormal symptom natural to an aged person and predict the dotage or weakness of legs and loins by detecting the acceleration in walking by an acceleration sensor installed to the aged person, and judging the output signal or processing data according a preset judgment condition. SOLUTION: When an aged person walking observing device 1 is installed to an aged person, the acceleration in walking of the aged person is detected by an acceleration sensor 2. Output signals Ssx... according to acceleration outputted from one or two or more of the acceleration sensor 2 are imparted to an abnormal walking detecting function part 3. The output signals Ssx... are converted into processing data Ds, and the processing data Ds are judged by one or two or more preset judgment conditions. The judgment conditions are set in conformation to the detected abnormal walking, or rocking (stumbling) and/or falling. When all the judgment conditions are satisfied, an abnormal walking is judged.
