Selective gesturing input to a surgical navigation system
First Claim
1. A method for selective gesturing input to a surgical navigation system within a sterile field, comprising:
- configuring an array with a first marker and a second marker, wherein the first marker and the second marker are distinguishable by a tracking system;
exposing the array to a measurement field of the tracking system;
occluding the exposure of either the first marker or the second marker to the tracking system within the sterile field; and
assigning the occlusion of the first marker as a first input and assigning the occlusion of the second marker as a second input to the computer system, wherein the first input is different than the second input.

Abstract
A surgical navigation system uses selective gesturing within a sterile field to provide inputs to a computer, which can reduce surgery time and costs. The teachings comprise configuring an array with at least a first marker and a second marker; exposing the array to a measurement field of the tracking system; occluding the exposure of either the first marker or the second marker to the tracking system within the sterile field; and assigning the occlusion of the first marker as a first input and assigning the occlusion of the second marker as a second input to the computer system, wherein the first input is different than the second input.

6. A computer readable storage medium storing instructions that, when executed by a computer, cause the computer to perform selective gesturing in a surgical navigation system that includes an array having first and second markers and a tracking system, the selective gesturing comprising the following:
-
identifying the array with the tracking system when the array is exposed to a measurement field of the tracking system; and
recognizing the occlusion of the first marker from the tracking system as a first input and recognizing the occlusion of the second marker from the tracking system as a second input that is different than the first input. - View Dependent Claims (7, 8, 9, 10)

11. A surgical navigation system, comprising:
-
a tracking system having a measurement field;
first and second markers that are distinguishable by the tracking system when exposed to the measurement field;
means for recognizing occlusion of the first marker and occlusion of the second marker from the measurement field;
means for causing a first action in response to the occlusion of the first marker; and
means for causing a second action in response to the occlusion of the second marker, wherein the second action is different than the first action. - View Dependent Claims (12, 13, 14, 15, 16)
