Title:
DIGITAL CURSOR DISPLAY LINKED TO A SMART PEN
Document Type and Number:
WIPO Patent Application WO/2014/066689
Kind Code:
A3
Abstract:
A system and a method are disclosed for calibrating writing on a writing surface to a digital document. One or more calibration parameters associated with a writing surface and a digital document of a display device are determined. The calibration parameters indicate a spatial offset between a reference position on the writing surface and a reference position in the digital document. A gesture captured by a smart pen is received. The gesture includes a sequence of spatial positions representing movement of the smart pen with respect to the writing surface. The sequence of spatial positions is mapped to a sequence of spatial positions in the digital document based on the calibration parameters.
