AI Technical Summary

Technical Problem

Conventional detection systems fail to detect signs of changes in a person's physical state, particularly in the context of mild cognitive impairment, which is an early symptom of dementia.

Method used

A sign detection system comprising a terminal device and a sign detection device connected via a network, which includes an input reception unit, a state estimation unit, a difference value recording unit, a difference value prediction unit, and a sign detection unit to detect abnormalities based on biological information and predict future changes.

Benefits of technology

Enables the detection of signs of abnormality in users, allowing for timely notifications and interventions, such as recommending preventive measures or clinical trials, by analyzing biological data and predicting future states.

Abstract

To detect a preindication on abnormality of a user.SOLUTION: A preindication detection system includes: a terminal device; and a predominant detection device. The predominant detection device has: an input reception unit that receives an input of bio-information associated with the terminal device and acquired from a user, and information on an input date / time of when the bio-information is input; a state estimation unit that estimates, on the basis of the bio-information, at least one or more kinds of index values indicative of a state of the user; a differential value recording unit that records a first differential value between a maximum value and minimum value of the at least one or more kinds of index values calculated for each first prescribed period from information indicative of a change in respective index values of at least the one or more kinds of index values; a differential value prediction unit that predicts a second differential value after a second prescribed period, using a plurality of recorded first differential values and the information on the input date / time; and a preindication detection unit that, when a degree of change in the first differential value after the second prescribed period, and the predicted second differential value satisfy a prescribed condition, detects a preindication of abnormality of the user.SELECTED DRAWING: Figure 9
