PROBLEM TO BE SOLVED: To detect occurrence of an irregular situation due to falling of users even when an impact by the falling is relatively low.SOLUTION: An irregularity detection terminal includes, with the irregularity detection terminal carried by users,: a motion sensor; falling detection means; body motion detection means; and irregularity determination means. The motion sensor is configured to detect a motion of the irregularity detection terminal to output motion data, and the falling detection means is configured to, when the motion data satisfies a first condition about a falling possibility of users, detect the falling thereof, and when the motion data satisfies a second condition different from the first condition, detect a quasi-falling as an event equivalent to the falling. The body motion detection means is configured to detect a body motion of the user on the basis of the motion data output by the motion sensor. The irregularity determination means is configured to determine that irregularity occurs in the user when the falling is detected, and when the quasi-falling is detected, monitor the detection of the body motion by the body motion detection means for a first period after the body motion is detected, and when the body motion of a prescribed condition is not detected during the monitoring, determine that the irregularity occurs in the user.SELECTED DRAWING: Figure 8 |
