Provided are a method and apparatus for compensating for an acceleration error in an inertial navigation system (INS). The apparatus includes a motion detector that detects the motion of the INS and outputs information on stationary time intervals during which the INS is stationary and a moving time interval during which the INS is moving; a sensor portion that measures accelerations of the INS for the stationary time intervals and moving time interval, respectively; an error model determiner that determines an acceleration error corresponding to the moving time interval using accelerations measured during the stationary time intervals and outputs an acceleration subjected to correction of the acceleration error for the moving time interval; and a position calculator that integrates the corrected acceleration for the moving time interval and outputs the position of the INS.

An input device includes a sensor configured to generate a signal related to a change in inertia around at least one axis of the input device in response to a contacting of the input device. A processor is configured to receive the signal from the sensor to determine whether the change in inertia around the at least one axis of the input device corresponds to a tapping of the input device. The processor is further configured to identify a contacted region of the input device based on a direction of the change in inertia around the at least one axis of the input device when the change in inertia corresponds to a tapping of the input device
