Abstract
A method and an apparatus for determining a carelessness of a driver may include detecting an object having an impedance substance by capacitive sensors provided in a headrest of a seat of a vehicle, detecting changes in electrostatic capacity by the capacitive sensors, measuring distance values between the object having the impedance substance and the capacitive sensors by using the changes in electrostatic capacity detected by the capacitive sensors, and determining whether the object having the impedance substance may be in a careless state by using the distance values.
