Augmented reality system controlled by probe position
First Claim
1. A guide system, comprising:
- a data processing apparatus for generating one or more images of a subject, said images being co-registered with the subject;
a display for displaying the images to the user;
a probe; and
a tracking unit for tracking the location of the probe and transmitting said location to the data processing apparatus,wherein, said data processing apparatus generates said co-registered images of the subject in a main display area when the probe is within a defined three-dimensional visualization region, and upon a user moving the probe to a defined three-dimensional interface region outside of the visualization region, the data processing apparatus ceases to generate the co-registered images and causes the display in the main display area of an icon representing the probe and one or more virtual buttons, each of said virtual buttons being associated with a corresponding instruction to the system,and wherein the data processing apparatus is arranged to obtain a selection by the user of any of the virtual buttons, said selection effected by positioning the physical probe to position said icon relative to the apparent position of said virtual button, and to modify the generated images based on the selection.

Abstract
A guide system for use by a user who performs an operation in a defined three-dimensional region is disclosed, the system including a data processing apparatus for generating images of the subject of the operation in co-registration with the subject, a display for displaying the images to the user, a probe having a position which is visible to the user, and a tracking unit for tracking the location of the probe by the system and transmitting that location to the data processing apparatus, the data processing apparatus being arranged, upon the user moving the probe to a selection region outside and surrounding the defined region, to generate one or more virtual buttons, each of the buttons being associated with a corresponding instruction to the system, the data processing apparatus being arranged to register a selection by the user of any of the virtual buttons, the selection including positioning of the probe in relation to the apparent position of that virtual button, and to modify the computer-generated image based on the selection.

12. A method of controlling an image guided system used in a defined three-dimensional visualization region, said system including a data processing apparatus for generating images of a subject in co-registration with the subject, a display for displaying the images to a user, a probe, and a tracking unit for tracking the location of the probe and transmitting that location to the data processing apparatus, said method comprising:
-
interacting with the image guided system in a display mode when the probe is within the visualization region, wherein images of the subject are displayed in a main display region; and interacting with the image guided system in a control mode when the probe is out of the visualization region but within a defined three-dimensional interface region; wherein, when the probe is within the interface region the data processing apparatus obtains the position of the probe, ceases to generate the co-registered images, and generates in the main display area an image of an icon representing the probe and one or more virtual buttons, each of the virtual buttons being associated with a corresponding instruction to the system, wherein the user selects one of said buttons by positioning the physical probe in 3D space so as to position the representative icon relative to the apparent position of the button, and wherein the data processing apparatus sets or modifies display parameters for said display mode in response to the instruction corresponding to the selected button. - View Dependent Claims (13, 14, 15, 16, 17)
