First Claim
Patent Images
1. A method for tracking a hover event on a digitizer sensor that treats hover and touch events differently, the method comprising:
- configuring at least one parameter of the digitizer sensor for hover tracking, wherein the at least one parameter is configured differently than for touch tracking;
detecting a pattern of input signals from a plurality of conductive lines on the digitizer sensor; and
defining a tracking point responsive to the pattern of hover input signals detected.

Abstract
A method and system for tracking a hover event on a digitizer sensor that treats hover and touch events differently comprises configuring at least one parameter of the digitizer sensor for hover tracking; wherein the at least one parameter is configured differently than for touch tracking, and detecting a pattern of input signals from a plurality of conductive lines on the digitizer sensor defining a tracking point responsive to the pattern of hover input signals detected.
