Abstract
Disclosed herein are a device for detecting motions and a method for detecting motions. The device for detecting motions includes a sensor detecting motions to output detection result signals; an accumulation operation unit accumulatively summing absolute values of the detection result signals in a preset accumulation period to derive signal accumulation values; a motion determination unit comparing the signal accumulation values with a preset first reference value to determine whether the motions are present; and an output unit outputting motion detection signals according to determination results of the motion determination unit. By this configuration, the exemplary embodiments of the present invention can reflect a size of the detection result signals to motion detection while improving inaccuracy of the motion detection according to a fixing of a threshold value.
