Abstract

A body part position detector 12 (or detectors) provides information regarding the position of a predetermined body part to a virtual image tactile-entry information interface generator 12. The latter constructs a virtual image of the information interface that is proximal to the body part and that is appropriately scaled and oriented to match a viewer'"'"'s point of view with respect to the body part. A display 13 then provides the image to the viewer. By providing the image of the information interface in close proximity to the body part, the viewer will experience an appropriate haptic sensation upon interacting with the virtual image.

Claims

1. A method comprising:

determining a present position of at least a predetermined portion of an individual'"'"'s body;

forming a virtual image of a tactile-entry information interface;

forming a display that includes the virtual image of the tactile-entry information interface in proximal and substantially fixed relationship with respect to the predetermined portion of the individual'"'"'s body.

2. The method of claim 1 wherein determining a present position of at least a predetermined portion of an individual'"'"'s body includes determining a present position of at least an appendage of the individual'"'"'s body.

3. The method of claim 1 wherein forming a virtual image of a tactile-entry information interface includes forming a virtual image that includes at least one of a keypad, a switch, a sliding device, a joystick, a drawing area, and a wheel.

4. The method of claim 1 wherein forming a display that includes the virtual image of the tactile information interface in proximal and substantially fixed relationship with respect to the predetermined portion of the individual'"'"'s body includes forming a display wherein at least a portion of the tactile information interface is at least substantially conformal to a physical surface of the predetermined portion of the individual'"'"'s body.

5. The method of claim 1 wherein forming a display that includes the virtual image of the tactile information interface in proximal and substantially fixed relationship with respect to the predetermined portion of the individual'"'"'s body includes forming a display wherein at least a portion of the tactile information interface is substantially coincident with a physical surface of the predetermined portion of the individual'"'"'s body.

6. The method of claim 5 wherein forming a display wherein at least a portion of the tactile information interface is substantially coincident with a physical surface of the predetermined portion of the individual'"'"'s body includes forming a display wherein at least a portion of the tactile information interface is substantially coincident with an exposed skin surface of the predetermined portion of the individual'"'"'s body.

7. The method of claim 1 and further comprising presenting the display to the individual.

8. The method of claim 7 wherein presenting the display to the individual includes presenting the display to the individual using a head-mounted display.

9. The method of claim 7 wherein presenting the display to the individual includes detecting an input from the individual indicating that the display is to be presented.

10. The method of claim 1 and further comprising presenting the display to at least one person other than the individual.

11. An apparatus comprising:

at least one body part position detector;

a virtual image tactile-entry information interface generator having an input operably coupled to the position detector and an output providing a virtual image of a tactile-entry information interface in a proximal and substantially fixed relationship to a predetermined body part;

a display operably coupled to the virtual image tactile-entry information interface wherein the display provides an image of the tactile-entry information interface in a proximal and substantially fixed relationship to the predetermined body part, such that a viewer will see the predetermined body part and the tactile-entry information interface in proximal and fixed association therewith.

12. The apparatus of claim 11 wherein at least one body part position detector includes at least one of a visual position marker, a magnetic position marker, a radio frequency position marker, a pattern-based position marker, a gesture recognition engine, a shape recognition engine, and a pattern matching engine.

13. The apparatus of claim 11 wherein the virtual image tactile-entry information interface generator includes generator means for generating the virtual image of the tactile-entry information interface.

14. The apparatus of claim 13 wherein the generator means further combines the virtual image of the tactile-entry information interface with a digital representation of the predetermined body part.

15. The apparatus of claim 11 wherein the display comprises a head-mounted display.

16. The apparatus of claim 15 wherein the head-mounted display includes at least one eye interface.

17. The apparatus of claim 16 wherein the head-mounted display includes at least two eye interfaces.

18. The apparatus of claim 16 wherein the at least one eye interface is at least partially transparent.

19. The apparatus of claim 16 wherein the at least one eye interface is substantially opaque.

20. The apparatus of claim 11 wherein the virtual image of a tactile-entry information interface includes at least one of a keypad, a switch, a sliding device, a joystick, a drawing area, and a wheel.

21. The apparatus of claim 11 wherein at least part of the image of the tactile-entry information interface appears on the display to be disposed substantially on the predetermined body part.

22. An apparatus for forming a virtual image of a tactile-entry information interface having a substantially fixed predetermined spatial and orientation relationship with respect to a portion of an individual'"'"'s body part, comprising:

position detector means for detecting a present position of the individual'"'"'s body part with respect to a predetermined viewer'"'"'s point of view;

image generation means responsive to the position detector means for providing a virtual image of a tactile-entry information interface as a function, at least in part, of;

the substantially fixed predetermined spatial and orientation relationship; and

the predetermined viewer'"'"'s point of view;

display means responsive to the image generation means for providing a display to the predetermined viewer, which display includes the individual'"'"'s body part and the virtual image of the tactile-entry information interface from the predetermined viewer'"'"'s point of view.

23. The apparatus of claim 22 and further comprising interaction detection means for detecting spatial interaction between at least one monitored body part of the individual and an apparent location of the virtual image of the tactile-entry information interface.
