Abstract
With electronic documents increasingly replacing paper based ones there is a need to convert handwriting and drawing into electronic formats. Current solutions have significant drawbacks due to their bulkiness, cost and limited performance. The proposed invention describes a new compact, light weight and low power system capable of electronically capturing handwriting and drawing. This invention enables the use of tiny MEMS based sensors such as accelerometers, gyroscopes and magnetometers to capture the user's hand motion in real time. It employs specialized algorithms taking advantage of the unique characteristics of human handwriting and drawing to enable the embedded software to accurately reproduce the pen strokes from the raw sensor data.
