Abstract

A method is described that allows the user to use a mouse to create a horizontal line, maximizing flexibility and minimizing operator distraction. Suppose the first click ends at time t1 and the second click begins at time t2. Further, suppose at time t1 the mouse occupies coordinates (x1,y1) and by time t2 the user has moved the mouse to (x2, y2). When the first click ends at time t1, the horizontal line H has been chosen. Simultaneously, the first endpoint is selected. But until the second click, the second endpoint (and thus the line segment appearing on the screen) is entirely redefineable. By assumption, the final definition of the second endpoint will occur at time t2.
