<p>A non-marking, writing system simulates a physical writing system which has characteristic ranges of writing resistance, sound, resilience and thermal conductivity. The non-marking writing system includes a non-marking writing instrument (12) having an elongated shank (70) with opposite ends. A non-marking tip (76) is connected to one end of the shank (70) for engagement against and movement across a writing surface (46). The writing surface (46) onto and across which the tip (76) is moved for non-marking writing, creates an actual writing resistance. The tip (76) is structured and made of selected material so that the actual writing resistance falls within the characteristic range of writing resistance for the physical writing system.</p> |
