Abstract

A coordinate input device that selects actual write points from coordinates that can be combined in different ways to define a greater number of potential write points. In the example of detecting X-coordinates and Y-coordinates that can be combined into X,Y pairs defining potential write points, the device identifies as X,Y pairs for actual write pairs the X,Y combinations that are most likely to correspond to actual write points, based on factors such as the time of detection of an X-coordinate relative to the times of detection of Y-coordinates (or vice versa), or the distances between actual points found in a preceding time period and the potential points of a current time period, or the distances between coordinates of actual points found in a preceding time period and corresponding coordinates of potential write points identified in a current time period.
