Abstract: The user interface system provides a mouse for inputting a time segment by pointing to an arbitrary position of the display screen. Displayed in a window, the time segment has a position and length to indicate hours or days. The segment editor displays the segment according to the length which is designated by the mouse. Segments may be duplicated from one window to another. The database entry stores the position and length of the time segment. To avoid or lessen scrolling of time segment data, a window may divided either horizontally or vertically when desired data is located far apart. Multiple windows displayed on the screen may be scrolled synchronously in one direction and independently scrolled in the opposite direction. Windows with different scaled information may be display simultaneously and synchronously scrolled.

Abstract: The user interface system provides the input means for inputting a segment by pointing out an arbitrary position of the display screen with the input unit such as a mouse for pointing out arbitrary positions of the display screen. The segment has a position and a length to indicate hours or days. The segment editor displays the segment according to the length which is designated by the input unit such as a mouse. The database entry stores the data indicated by the position and the length of the segment as entered data.Thus, data is entered by inputting a segment. Therefore, data such as a time and a date are not needed to be entered from a keyboard. Since data entry is made by drawing a segment by using a mouse, operation is easy. Furthermore, since the length of the segment shows the hours or period visually to a system operator, the chances of errors are lessened.The user interface system provides a system to input additional information for a segment displayed by the segment editor.
