Digital Cursor Display Linked to a Smart Pen

摘要

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.

1. A method for calibrating writing on a writing surface to a digital document, the method comprising:
determining one or more calibration parameters associated with a writing surface and a digital document of a display device, the one or more calibration parameters indicating:
a spatial offset between a reference position on the writing surface and a reference position in the digital document, anda scaling factor between the writing surface and the digital document; receiving a gesture captured by a smart pen, the gesture comprising a sequence of spatial positions of the smart pen representing movement of the smart pen with respect to the writing surface; mapping, by a computing device, the sequence of spatial positions of the smart pen to a sequence of spatial positions in the digital document based on the one or more calibration parameters; rendering the received gesture in the digital document on the display device based on the mapped sequence of spatial positions in the digital document.
