Method and apparatus for transforming sensor signals into graphical images

A method for generating a graphical image of strokes made by a writing instrument, the method comprising:

• obtaining data indications of strokes, via a plurality of sensors, made with the writing instrument;
• performing a transform on data from the sensors to generate transformed data;
• mapping the transformed data to a graphical image of the strokes;
• and
• adjusting the transformed data by:
• receiving sensor data corresponding to a tip of the writing instrument being traced over a predetermined pattern;
• comparing the sensor data to a known configuration of the predetermined pattern;
• and
• adjusting the transformed data based on a difference between the sensor data and the known configuration.
