Abstract

A method and apparatus providing visual feedback to a computer user while dragging selected text is described. As its first step, the processing logic creates a text object from the selected text once the computer user has initiated a drag. Simultaneously, the selected text is visually de-emphasized. Secondly, the processing logic snaps the text object to the cursor so that the text object follows the cursor without obscuring text at the insertion point. Finally, when the computer user selects the final insertion point, the selected text is visually zoomed from the source location to the final insertion point.

Claims

1. An apparatus providing visual feedback while manipulating text, the apparatus comprising:

a) a computer system including;

1) a central processing unit;

2) a display device for displaying images and text, the display device being coupled to the central processing unit;

3) a control device for interactively positioning a visible symbol on the display device, the control device having a button having a first position and a second position, the control device being coupled to the central processing unit;

b) a first process coupled to the central processing unit, the first process creating a text object from selected text;

c) a zooming process coupled to the central processing unit, the zooming process causing the zooming from a first bounding rectangle for the selected block of text at the source location to a second bounding rectangle for the selected block of text at the destination location such that the movement of the first bounding rectangle to the size and location of the second bounding rectangle at the destination location is animated.

2. A method for providing visual feedback to a computer user while manipulating selected text displayed on a display device of a computer system, the computer system including a control device for interactively positioning a visible symbol on the display device, the control device having a button having a first position and a second position, the method comprising:

a) creating a text object from the selected text when the button is in the second position while the visible symbol is over the selected text at the source location;

b) zooming from a first bounding rectangle for the selected block of text at a source location to a second bounding rectangle for the selected block of text at the destination location such that the movement of the first bounding rectangle to the size and location of the second bounding rectangle at the destination location is animated.
