The present invention discloses a method and an apparatus for precisely perceiving an indoor activity. The method may include: receiving a vibration signal on a floor by using multiple vibration sensors disposed according to a preset rule; and determining a location of a vibration source according to a phase difference of a vibration signal of the same vibration source in different vibration sensors. The monitoring performed on the indoor activity in the present invention can be performed without disturbing the monitored person, and can resolve the concern about leakage of privacy of the monitored person.

Method and apparatus for precisely perceiving indoor activity

The present invention discloses an eye motion sensing method, a flexible contact body, an external sensing coil, and a system. The method may include: sensing an eye motion by using a servo motion signal of a permanent magnet implanted into a flexible contact body; applying at least four coils disposed externally on a same plane, and monitoring a servo motion of the permanent magnet according to an electromotive force in the coils; and converting the electromotive force to restore an eye motion signal. The present invention can use the sensing coils distributed around an eyepit to detect the electromotive force generated when the eye motion leads to the servo motion of the flexible contact body, and analyze the electromotive force. Accordingly, the eye motion triggered by a perceptual task can be analyzed objectively.

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 &#x394;S, and time occupied by resultant acceleration below the reference line is greater than a low acceleration time threshold &#x394;T, determining that the human body tumbles.
