Stylus tilt tracking with a digitizer |
| 摘要 |
A method for detecting orientation of a stylus with respect to a digitizer sensing surface includes detecting a signal emitted by a stylus at a plurality of coordinates on a digitizer sensing surface, determining coordinate of a writing tip of the stylus, defining at least one feature characterizing an asymmetrical spread of the stylus signal on the digitizer sensing surface with respect to the writing tip coordinate, and characterizing an orientation of the stylus responsive to the characterization of the asymmetrical spread. |

1. A method comprising:
detecting a signal emitted by a stylus at a plurality of coordinates on a digitizer sensing surface; determining coordinates of a writing tip of the stylus; defining at least one feature characterizing an asymmetrical spread of the stylus signal on the digitizer sensing surface with respect to the writing tip coordinates; defining asymmetry in a peak formed by amplitudes of the signal detected at the plurality of coordinates; and detecting an orientation of the stylus with respect to a digitizer sensing surface based on the characterization of the asymmetry in the peak. |
