A display control unit (101) displays a key image, which serves as an operation target, etc. on a display unit. An area memory unit (103) stores a reception area (area information) corresponding to the displayed key image. A detecting unit (104) senses a user's touching operation and detects its touch position. A determining unit (105) makes determinations whether the detected touch position is within the range of the reception area stored in the area memory unit (103), etc. A time measuring unit (106) measures a time period that has elapsed since the touching operation. When a touching operation is detected, an area control unit (107) expands a reception area that includes the touch position to a predetermined range. Thereafter, the area control unit (107) reduces the expanded reception area to its original size when the time measuring unit (106) measures a predetermined time period.

Multiple displays are placed side by side. A key image to be drag-and-dropped is displayed on a first display. An actual drop target area into which the key image is to be dropped is displayed on the rest of the displays. The key image is held by placing a cursor thereon and pressing a right click button of a mouse. In response to this, a drop window that is a reduced image of the drop target area is displayed on the first display. The cursor is moved onto the drop window by operating the mouse with the right click button pressed. Releasing the right click button in a desired position in the drop window drops the key image. Based on a drop position in the drop window, the key image is dropped in a corresponding position in the actual drop target area.

A system and method of searching multimedia databases using key images that returns image content ranked by degree of similarity to the key-images. A user accesses the search engine via a graphic user interface (GUI) that allows the user to enter key-images using drag-and-drop technology.
