Abstract

A method for determining an orientation of an object includes determining a plurality of boundary values defining a predetermined range of movement of the object; dividing the range into position segments using the plurality of boundary values; moving a movable portion of the object to a current position; determining a change in object position by comparing a prior object position to the current position; determining the number of position segments corresponding to the change of the object position; outputting a signal corresponding to the number of segments to a control device; determining a scaling value for any or all of the position segments corresponding to a desired position amplification or position attenuation scheme; and controlling movement of a selected image or device based on the amplification or attenuation scheme such that movement of the moveable portion of the object causes disporportional movement of the image or device.

Claims

1. A method for determining the orientation of an object comprising the steps of:

determining a plurality of boundary values defining a predetermined range of movement of the object;

dividing the range into position segments using said plurality of boundary values;

moving a movable portion of the object to a current position;

determining a change in object position by comparing a prior object position to said current position;

determining the number of position segments corresponding to the change of the object position;

outputting a signal corresponding to said number of segments to a control device;

determining a scaling value for any or all of said position segments corresponding to a desired position amplification or position attenuation scheme; and

controlling movement of a selected image or device based on said amplification or attenuation scheme such that movement of the moveable portion of the object causes disporportional movement of said image or device.

2. The method of claim 1 wherein determining a plurality of boundary values comprises the steps of:

moving the movable portion of the object to a first boundary position;

activating acquisition means to record said first boundary position;

moving said movable portion to a second boundary position; and

activating acquisition means to record said second boundary position.

3. The method of claim 2 further comprising the step of activating indication means to confirm recording of said first and second boundary position.

4. The method of claim 2 wherein determining a plurality of boundary values further comprises the steps of:

moving the moveable portion of the object to a third boundary position located between said first boundary position and said second boundary position;

activating acquisition means to record said third boundary position.

5. The method of claim 4 further comprising the steps of:

determining the number of position segments between the first boundary position and the third boundary position; and

determining the number of position segments between the second boundary position and the third boundary position.

6. The method of claim 5 further comprising the steps of:

determining the current position of the movable portion of the object relative to said third boundary position; and

determining the prior position of the movable portion of the object relative to said third boundary position.

7. The method of claim 4 further comprising the step of activating indication means to confirm recording of said third boundary position.

8. A method for determining the orientation of an object comprising the steps of:

determining a plurality of boundary values defining a predetermined range of movement of a moveable portion of a human body relative to a human torso;

dividing the range of movement of the moveable portion of the human body into position segments using said plurality of boundary values;

moving the moveable portion of the body to a current position;

determining a change in the moveable portion position by comparing a prior moveable portion position to said current position;

determining the number of position segments corresponding to the change of the moveable portion position;

outputting a signal corresponding to said number of segments to a control device;

determining a scaling value for any or all of said position segments corresponding to a desired moveable portion position amplification or moveable portion position attenuation scheme; and

controlling movement of a selected image or device based on said amplification or attenuation scheme such that movement of the moveable portion of the body causes disproportional movement of said image or device.

9. The method of claim 8 wherein determining a plurality of boundary values comprises the steps of:

moving the moveable portion of the body to a first boundary position;

activating acquisition means to record said first boundary position;

moving the moveable portion of the body to a second boundary position; and

activating acquisition means to record said second boundary position.

10. The method of claim 9 further comprising the step of activating indication means to confirm recording of said first and second boundary position.

11. The method of claim 9 wherein determining a plurality of boundary values further comprises the steps of:

moving the moveable portion of the body to a third boundary position located between said first boundary position and said second boundary position;

activating acquisition means to record said third boundary position.

12. The method of claim 11 further comprising the steps of:

determining the number of position segments between the first boundary position and the third boundary position; and

determining the number of position segments between the second boundary position and the third boundary position.

13. The method of claim 12 further comprising the steps of:

determining the current position of the movable portion of the body relative to said third boundary position; and

determining the prior position of the movable portion of the body relative to said third boundary position.

14. The method of claim 11 further comprising the step of activating indication means to confirm recording of said third boundary position.
