Hybrid digital and physical writing surface with transformational ink effects

摘要

The present invention provides a new and useful hybrid digital and physical interactive writing surface. A user writes on a physical writing surface using thermal ink. Underneath the physical writing surface is a heating layer. Once the heating layer is activated, the thermal ink disappears. Meanwhile, sensors capture a user's strokes while writing, and a computing device digitally stores the captured strokes. Therefore, there is zero-time delay or lag time between writing on the physical writing surface and its appearance. Finally, there is no need to erase any writing nor use other sheets or boards after one use because the writing is automatically erased.
