ABSTRACT:
Aspects of the invention provide virtual hover zones. When a user lowers a hovering stylus while remaining within a hover zone, cursor control is modified to be more easily controllable by the user. If the user pauses the stylus in mid-air before lowering the stylus, and if the stylus remains within the hover zone, then upon touchdown the cursor may be moved to the projection of the location where the stylus was paused. Any action that may be taken in response to the touch down may be sent to the projection location as well. Also provided are cursor control zones. A dampening zone may be used to provide dampened cursor movement feedback in response to movement input provided by a pointing device. Also, a dead zone may be used to prohibit cursor movement in response to movement input provided by the pointing device.
