Targeting in a stylus-based user interface

摘要

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.

主权项

1. A computer-memory device storing computer-executable instructions that, when executed, enable a computing device to perform a method of receiving an input using a touch-sensitive surface, the method comprising:
detecting a presence of an input device apart from the touch-sensitive surface, wherein a movement of the input device apart from the touch-sensitive surface is effective to move a cursor; determining a cursor location and a cursor control zone having a boundary that at least partially circumscribes the cursor location and that is a first distance away from the cursor location; measuring a speed at which the input device is moved relative to the touch-sensitive surface; and decreasing the cursor control zone when the speed exceeds a threshold, wherein a movement of the cursor is dampened when the cursor is positioned inside the cursor control zone.
