A marking device is provided. The marking device (MD) includes an elongated housing that has a tip configured to contact a surface. The MD also includes a pressure sensor disposed within the housing. The pressure sensor is coupled to the tip and is configured to detect when the tip contacts the surface. The MD further includes first and second acceleration sensors disposed within the housing and adjacent the tip of the MD. The first and second acceleration sensors are configured to sense acceleration of the tip in first and second directions. Responsive to the sensing of acceleration, first and second acceleration sensors generate a signal indicative of acceleration in first and second directions. The MD also includes a conversion device configured to receive first and second signals and convert first and second signals into at least one computer readable signal.
