An adaptive interface providing apparatus and method of setting an individual degree of attention for a specific driver based on an average degree of attention are provided. The adaptive interface providing apparatus includes a statistics database unit which analyze a predetermined statistical population, extracts a context feature including an average degree of attention required when a driving operation, a state of a car, or an external environment changes, a degree of attention required for interface manipulation when a driver manipulates interfaces of a car, and a similarity between the functions of the interfaces using at least one of a sensor, an RFID, and a GPS and stores and manages the context feature; an adjusting unit which senses a change in at least one of the driving operation, the state of a car, and the external environment using at least one of the sensor, the RFID, and the GPS and adjusts an individual degree of attention based on the extracted context feature and the average degree of attention according to the sensed change; and a safety determining unit which determines whether or not a sum of the individual degree of attention and the degree of attention required for interface manipulation when the driver manipulates the interfaces is larger than a predetermined threshold degree of safety attention required for safe driving.
