Abstract

An inventive system and method for touch free operation of an ablation workstation is presented. The system can comprise a depth sensor for detecting a movement, motion software to receive the detected movement from the depth sensor, deduce a gesture based on the detected movement, and filter the gesture to accept an applicable gesture, and client software to receive the applicable gesture at a client computer in an ablation workstation for performing a task in accordance with client logic based on the applicable gesture. The system can also comprise hardware for making the detected movement an applicable gesture. The system can also comprise voice recognition providing voice input for enabling the client to perform the task based on the voice input in conjunction with the applicable gesture. The applicable gesture can be a movement authorized using facial recognition.

First claim

What is claimed is:

1. A system for touch-free operation of an ablator workstation by an associated user, comprising:
a depth sensor configured to detect an initial location and a subsequent location of a body part of the associated user; and
a processor with a memory device, wherein the memory device is configured to store instructions that, when executed by the processor, cause the processor to:
receive the detected initial location and the detected subsequent location of the body part,
deduce a gesture based on the detected initial location and detected subsequent location,
validate the gesture based on a physical characteristic of the gesture,
determine whether the validated gesture is defined with an ablator task,
cause the ablator workstation to perform the ablator task when the validated gesture is defined,
compare a difference between an initial movement location and a subsequent movement location,
authorize the gesture as being from the associated user when the difference is within a predicted location, and
associate the ablator workstation to the user, thereby giving control of the ablator workstation to the associated user, wherein the ablator workstation is disassociated from the associated user after a period of motionlessness.

2. The system according to claim 1 , wherein the ablator task with which the validated gesture is defined is based on a state of the processor.

3. The system according to claim 1 , wherein the gesture is authorized when a hardware device is operated during the gesture.

4. The system according to claim 1 , wherein a different ablator task is caused to be performed when voice input is received in conjunction with the gesture.

5. A method for touch-free operation of an ablator workstation by an associated user, comprising:
detecting, by a depth sensor, an initial location and a subsequent location of a body part of the associated user,
receiving, by a processor, detected initial location and subsequent location of the body part,
deducing, by the processor, a gesture based on the detected initial location and the detected subsequent location of the body part,
validating, by the processor, the gesture based on a physical characteristic of the gesture,
determining, by the processor, whether the validated gesture is defined with an ablator task,
causing, by the processor, the ablator workstation to perform the ablator task when the validated gesture is defined,
comparing, by the processor, a difference between an initial movement location and a subsequent movement location,
authorizing, by the processor, the gesture as being from the associated user when the difference is within a predicted location, and
associating, by the processor, the ablator workstation to the user, thereby giving control of the ablator workstation to the associated user, wherein the ablator workstation is disassociated from the associated user after a period of motionlessness.

6. The method according to claim 5 , wherein the ablator task with which the validated gesture is defined is based on a state of the processor.

7. The method according to claim 5 , wherein the gesture is authorized when a hardware device is operated during the gesture.

8. The method according to claim 5 , wherein a different ablator task is caused to be performed when voice input is received in conjunction with the gesture.

9. A system for touch-free operation of an ablator workstation by an associated user, comprising:
a depth sensor configured to detect an initial location and a subsequent location of a movement of a body part of the associated user; and
a processor with a memory device, wherein the memory device is configured to store instructions that, when executed by the processor, cause the processor to:
receive the detected movement of the body part,
deduce a gesture based on the detected movement of the body part,
validate the gesture based on a physical characteristic of the gesture,
determine whether the validated gesture is defined with an ablator task,
cause the ablator workstation to perform the ablator task when the validated gesture is defined,
compare a difference between an initial movement location and a subsequent movement location, and
authorize the gesture as being from the associated user when the difference is within a predicted location, wherein the ablator workstation is disassociated from the associated user after a period of motionlessness.

10. The non-transitory computer readable storage device according to claim 9 , wherein the ablator task with which the validated gesture is defined is based on a state of the processor.

11. The non-transitory computer readable storage device according to claim 9 , wherein the gesture is authorized when a hardware device is operated during the gesture.

12. The non-transitory computer readable storage device according to claim 9 , wherein a different ablator task is caused to be performed when voice input is received in conjunction with the gesture.

13. A non-transitory computer readable storage device storing a program of instructions executable by a machine to perform a method for touch-free operation of an ablator workstation by an associated user, comprising:
detecting location and motion movements of a body part of the associated user,
receiving detected location and motion movements of the body part,
deducing a gesture based on the received motion movement of the body part,
validating the gesture based on a physical characteristic of the gesture,
determining whether the validated gesture is defined with an ablator task,
causing the ablator workstation to perform the ablator task when the validated gesture is defined,
comparing a difference between an initial movement location and a subsequent movement location,
authorizing the gesture as being from the associated user when the difference is within a predicted location, and
associating the ablator workstation to the user, thereby giving control of the ablator workstation to the associated user, wherein the ablator workstation is disassociated from the associated user after a period of motionlessness.
