The present invention reduces overhead processing of a data processing system by storing a predetermined number of points corresponding to the position of a pointing device as it moves on a workpad or other touch sensitive input device. A predetermined number of points are stored in a buffer, wherein the predetermined number is dependent upon the type of pointing device (e.g., finger, stylus, etc.) used with the workpad. The stored points are periodically displayed or inked on a visual display at a rate of at least 20 times per second. As a result, the user moving the pointing device receives both tactile and visual feedback information similar to that provided by, a pencil used to make markings on a piece of paper. An alternative embodiment provides a similar reduction of overhead associated with erasing graphical information displayed on the visual display.
