Abstract: A ballistocardiogram (BCG) analysis apparatus, method, and system is provided for utilizing the BCG for a vehicle. A basic pattern is selected when measurement of a BCG is initiated. Data about BCG is measured for a predetermined period of time. Whether the basic pattern is suitable for the measured data is determined by comparing the measured data with the basic pattern. If the basic pattern is suitable for the measured BCG data, continuous data about the BCG is collected. Signal processing is performed based on pattern matching using the continuous data. A biological condition of the examinee is recognized using results of the signal processing. A posture of the examinee is measured, and if the posture of the examinee has changed, a pattern DB is searched, the basic pattern is changed to a suitable pattern, and then signal processing is performed.
