1. A method for selectively activating a virtual geometry, comprising:
- establishing a plurality of virtual geometries, each virtual geometry having a target feature and being available to be activated to guide an instrument to the target feature by restricting movement of the instrument within the confines of the virtual geometry;
displaying the plurality of virtual geometries on a display to a user;
receiving user input selecting a virtual geometry from the displayed plurality of virtual geometries; and
activating the selected virtual geometry;
wherein two or more of the plurality of available geometries overlap at an overlapping region, and wherein the selective activation of the virtual geometry based on the user input prevents forces associated with a first virtual geometry from interfering with forces associated with a second virtual geometry while the instrument is in the overlapping region.

Abstract
A method for selectively activating a virtual geometry includes establishing a plurality of virtual geometries, each virtual geometry having a target feature and being available to be activated to guide an instrument to the target feature by restricting movement of the instrument within the confines of the virtual geometry. The method further includes displaying the plurality of virtual geometries on a display to a user and receiving user input selecting a virtual geometry from the displayed plurality of virtual geometries. The virtual geometry is activated based on the selection.

11. A computer-assisted surgery system, comprising:
-
a processing circuit configured to establish a plurality of virtual geometries, each virtual geometry having a target feature and being available to be activated to guide an instrument to the target feature by restricting movement of the instrument within the confines of the virtual geometry; a display configured to display the plurality of virtual geometries to a user; an input/output device configured to receive user input; and a tracking system configured to track a position of a reference point of the instrument; wherein in response to the input/output device receiving user input selecting a virtual geometry from the displayed plurality of virtual geometries, the processing circuit is further configured to activate the selected virtual geometry; and wherein two or more of the plurality of available geometries overlap at an overlapping region, and wherein the selective activation of the virtual geometry based on the use input prevents forces associated with a first virtual geometry from interfering with forces associated with a second virtual geometry while the instrument is in the overlapping region. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
