The Estudia InkLink™ consists of a digital pen and a small receiving unit, which combines Ultrasound and infrared technologies, with sophisticated algorithms to enable an accurate tracking and positioning system that tracks the movement of the tip of the pen on any surface and converts the movement into a vector image of the user’s handwriting.  The digital pen transmits handwritings to the receiver unit for storage.
