Abstract
A human body tumbling detection method and device and a mobile terminal system are disclosed. The method may include: when detecting that resultant acceleration of a human body is less than a low acceleration threshold a, capturing a resultant acceleration sequence Iwithin fixed time; in a two-dimensional coordinate system using resultant acceleration and time as coordinate axes and aas a reference line, calculating a curve area above the reference line and a curve area below the reference line that are enclosed by curves in Icoordinates and the reference line; and when a difference between the curve area above the reference line and the curve area below the reference line is less than a curve area threshold ΔS, and time occupied by resultant acceleration below the reference line is greater than a low acceleration time threshold ΔT, determining that the human body tumbles.
