1. A method comprising:
- detecting a touch event;
determining at least one spatial characteristic of the touch event;
detecting a hover event;
determining at least one spatial characteristic of the hover event,wherein the at least one spatial characteristic of the touch event includes area on the digitizer sensor spanned by the touch event and the at least one spatial characteristic of the hover event includes area on the digitizer sensor spanned by the hover event; and
verifying or rejecting the touch event as an intended user interaction with a digitizer sensor based on the spatial characteristics determined for both the touch event and the hover event.

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.

18. A system comprising:
-
a digitizer sensor configured to detect touch input and hover input; a controller configured to determine spatial characteristic of a touch event and a spatial characteristic of a hover event and to verify the touch event as an intended user interaction or reject the touch event as an intended user interaction based on the spatial characteristics determined for both the touch event and the hover event, wherein the controller is operated to determine an area on the digitizer sensor spanned by the hover event;
determine location on the digitizer sensor of the hover event in relation to location on the digitizer sensor of the touch event; and
verify the touch event as the intended user interaction responsive to both the area spanned by the hover event and the location of the hover event in relation to the location of the touch event. - View Dependent Claims (19, 21)

20. A device comprising:
-
a display; a digitizer sensor proximate to the display, wherein the digitizer sensor is configured to detect touch input and hover input; a controller in communication with the digitizer sensor; and a circuit operated to determine a spatial characteristic of a touch event and a spatial characteristic of a hover event, both the touch event and the hover event detected with the digitizer sensor and to verify the touch event as an intended user interaction or reject the touch event as an intended user interaction based on the spatial characteristics determined for both the touch event and the hover event, wherein the circuit is operated to determine an area on the digitizer sensor spanned by the hover event;
determine location on the digitizer sensor of the hover event in relation to location on the digitizer sensor of the touch event; and
verify the touch event as an intended user interaction responsive to both the area spanned by the hover event and the location of the hover event in relation to the location of the touch event.
