Apparatus for generating exact vertical or horizontal motion-with a dual-axis input device

摘要

A user of a two-axis input device has the capability to automatically construct a vertical or horizontal line. The input device has a mechanical means that the user can implement to inhibit inputs submitted from either the X-axis or the Y-axis to the computer. As a result, the computer only receives inputs from the axis in the direction for which the user desires to draw the straight line.
