Abstract
According to various embodiments of the present invention, an individual's dangerous state detection-based situation information acquisition device may include: a sensor unit configured to detect an individual's state; a control unit configured to determine that the individual's state is a dangerous state when the rate of change of the maximum value of a sensor data stream detected by the sensor unit satisfies Equation 1 below; a camera configured to photograph the surroundings of the situation information acquisition device from the time when it is determined that the individual's state is a dangerous state; and a voice recorder configured to record sounds generated in the surroundings. Other embodiments may also be possible.

An individual's dangerous state detection-based situation information acquisition device, comprising:
- a sensor unit configured to detect an individual's state;
- a control unit configured to determine that the individual's state is a dangerous state when a rate of change of a maximum value of a sensor data stream detected by the sensor unit satisfies Equation 1 below;
- a camera configured to photograph surroundings of the situation information acquisition device from a point of time when it is determined that the individual's state is a dangerous state;
- and
- a voice recorder configured to record sounds generated in the surroundings:
