Direct Card Access Method

Disclosed is a method for easily accessing a card in a card-type database by using a scroll bar. The direct manipulation capability provided by this method is easy for novice users.

In a card-type database, data are displayed as a set of cards on a screen. Let N be the number of cards. The user needs to select a card to be displayed from these N cards. The disclosed method provides the function to select a card directly and easily by using a scroll bar.

Fig. 1 shows the structure of the scroll bar. The thumb can move anywhere in the scroll area. Let L be the width of the scroll area, T be the width of thumb and P be the thumb, position from the left side of the scroll area (Fig. 2). Then the Mth card appears on the screen, where M = (N-1)*P/(L-T)+1. Therefore, a card appears in a position corresponding to the position of the thumb on the scroll bar.

For example, when the thumb is at the left-most position in the scroll area, the first card is displayed because P=0. When the thumb is at the right-most position in the scroll area, the Nth card (the last card) appears because P=L-T.

A mouse click on the right arrow or left arrow brings the (M-1)th card (the previous card) or the (M+1)th card (the next card), where the current card is the Mth card.

The scroll bar is on the window displaying the set of cards.
