A method of generating parking availability information according to the present invention includes detecting at least one already parked vehicle from an image captured by a camera; converting object area information corresponding to the detected parked vehicle into real distance information; and generating parking availability information of a parking target vehicle based on the real distance information.

System and method for generating parking availability information

A navigation information providing device recognizes traveling status information of a vehicle senses a behavioral state or physiological state of a driver to recognize the driver's situation information and sets a rule including a form and a time for navigation information to be provided to the driver per traveling status information and driver's situation information. The navigation information providing device searches navigation information that corresponds to the driver's situation information and the vehicle's traveling status information, determines the form and time of navigation information to satisfy the rule, and provides navigation information to the driver according to the determined form and time.

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.

Adaptive interface providing apparatus and method

Provided are an apparatus and method for improving transmission control protocol (TCP) performance using path recovery notification over a wireless network. The apparatus includes: a path recovery manager which detects a mobile host recovered from a temporary disconnection state and then outputs a detection signal to notify the detection result; a path recovery notification manager which receives the detection signal and generates an ACK (acknowledgement) packet to inform a transmitting end that the mobile host is recovered; and a first packet transceiver which transmits/receives the generated ACK packet and a data packet. Accordingly, a temporary disconnection state of a wireless network is explicitly informed to a transmitting end so as to transmit only lost packets without performing unnecessary congestion control, thereby improving TCP performance.
