Abstract:
PURPOSE: A device for operating a reaction force effect for a haptic computer system is provided to generate/edit/play the reaction force effect used in the haptic computer system such as a haptic computer game on a computer screen as an interactive form. CONSTITUTION: A reaction force generator(120) generates the reaction force data for the reaction force data based on the information inputted from a user through a user interface(110). A reaction force editor(130) edits the reaction force data based on the information inputted from the user by providing an interactive interface through the user interface. A reaction force database(150) stores the edited/generated/inputted reaction force data. A reaction force player(140) plays the edited reaction force to the outside.

PURPOSE: An image information searching method using a color feature vector is provided to obtain H,S,I images from R,G,B images to extract small number of feature vectors while reflecting the local feature of the image to accelerate the image searching with improved accuracy. CONSTITUTION: The image information searching method using the color feature vector includes following steps. At first, a quality image is input. The color information of the input image is converted to Hue, Saturation and Intensity and the result is quantized. Then, the overall image is divided into predetermined size sub blocks. A mean, variation and asymmetrical distribution of the image divided into sub blocks are obtained. A clock feature vector for each sub block is obtained and the color feature vector is stored repeatedly corresponding to the number of divided sub blocks. All of the color characteristic vector are delivered into a classifier and a color classification code is generated. The image is compared with the images in a database by using the color classification code and a result image corresponding to a quality image is output.

본 발명은 칼라 특징 벡터를 이용한 영상정보 검색방법에 관한 것이다. 본 발명에서는 간략화된 칼라 특징 벡터를 이용한 영상정보 검색 기법을 제안한다. 칼라 정보를 이용한 영상 검색을 위하여, 영상이 처음부터 갖고 있는 R, G, B(빨간색, 초록색, 파란색)로부터 색조(H), 채도(S), 조도(I)값으로 변환하여 각각 16,2,2의 값으로 간단하게 양자화한다. 영상의 국부적 특성을 고려하기 위하여 부블럭으로 나누었다. 또한, 기존의 연구에서는 H,S,I 각각에서 똑같이 3개씩의 특징 벡터를 추출하여 전체로 9개의 특징 벡터를 비교하였으나, 처리 속도를 높이기 위하여 인식에 중요한 H에는 더 높은 가중치를 부여해서 H는 3개, S및 I는 각 1개씩의 특징 벡터를 추출하도록 한다. 칼라 특징 벡터로부터 칼라 부류 코드를 생성하여 영상 데이터베이스에 있는 대상 영성들의 칼라 부류 코드와 비교하여 질의 영상에 해당하는 결과 영상을 출력한다.
Abstract:
PURPOSE: A software framework for supporting a haptic application programming interface and a computer game system using the same are provided to support the haptic interface on a Windows OS(Operating System) based computer game giving an experiencing effect by applying the haptic interface to the computer game without modifying a game engine. CONSTITUTION: A haptic game device class layer(41) represents a hierarchical framework of each target haptic game device generating a vibration effect according to the force-feedback by loading a preset haptic effect. A haptic effect class layer(42) generates/manages various haptic effect systematically and efficiently. A device COM(Component Object Module) object management class(43) manages the COM devices for collectively representing the device for the PC peripheral device.
