Optical digitizer system with position-unique photoluminescent indicia

A digitizer system including a substrate having a position-unique photoluminescent indicia pattern. A stylus component receives optical signals indicative of the indicia pattern and determines therefrom the position of the stylus relative to the substrate. Methods of disposing indicia on the substra...

Zusammenfassung:	A digitizer system including a substrate having a position-unique photoluminescent indicia pattern. A stylus component receives optical signals indicative of the indicia pattern and determines therefrom the position of the stylus relative to the substrate. Methods of disposing indicia on the substrate, and styli suitable for sensing photoluminescent indicia are also described.
