ABSTRACT:
The present invention relates to a method of controlling movement of a cursor on a screen and a computer readable medium containing such a method as a program code.When using a graphic program which displays data in a graphical manner, it is often difficult to maintain control of the cursor. In particular, when a user attempts to draw a straight line using the cursor, it is difficult to control the cursor sufficiently accurately. The consequence is often not a straight line but one with steps of one or more pixels.Thus, the present invention is related to a method of controlling movement of a cursor on a screen, comprising:determining an initial position of said cursor; wherein the improvement lies indefining at least one corridor which includes said initial position;monitoring movement of said cursor to determine whether a final position of said cursor rests within the corridor, anddisplaying said movement as a line on said screen.
