Claims:

1. A steerable display system comprising:

a display element;

a position element to position an image generated by the display element the position element comprising:

steerable element;

an X-axis controller to pivot the steerable element around an X- axis;

a Y-axis controller to pivot the steerable element around a Y- axis;

wherein a movement of the steerable element is such that a user does not perceive motion;

such that the steerable element has a range of motion that enables the steerable display to be positioned and repositioned at a plurality of locations within a field of view of the user.

2. The steerable display system of claim 1 , further comprising:

a position validator, to verify an actual position of the steerable element and to adjust steerable display image data when the actual position is not an intended position.

3. The steerable display system of claim 1 , wherein the steerable element comprises one or more of: adjustable mirror, tunable prism, acousto-optical

modulator, adjustable display panel, a curved mirror, a diffractive element, and a Fresnel reflector.

4. The steerable display system of claim 1 wherein:

the steerable display has a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees.

5. The steerable display system of claim 1 , further comprising: an actuator to move the steerable element, the actuator comprising one of a piezo-electric element, a magnetic element, a nanomotor.

6. The steerable display system of claim 5, wherein the actuator has an absolute precision of +/- 0.75 arc minute, and a relative precision of 0.06 arc minute.

7. The steerable display system of claim 5, wherein a settling time is less than 2 ms.

8. The steerable display system of claim 1 , wherein the steerable element is a mirror having a diameter between 5mm and 15mm.

9. The steerable display system of claim 1 , wherein the position element is smaller than 5 mm x 12mm x 12 mm.

10. A steerable display system comprising:

a moveable display element;

position element to move the display element, to position an image generated by the display element, the position elements comprising:

flexible arms supporting the moveable display element;

a controller to pivot the steerable element around the axis-using the flexible arm;

wherein a movement of the steerable element is such that a user does not perceive motion;

such that the steerable element has a range of motion that enables the steerable display to be positioned and repositioned at a plurality of locations within a field of view of the user.

11. The steerable display system of claim 10, further comprising:

a position validator, to verify an actual position of the steerable element and to adjust steerable display image data when the actual position is not an intended position.

12. The steerable display system of claim 10, wherein the steerable element comprises one or more of: adjustable mirror, tunable prism, acousto-optical modulator, adjustable display panel, a curved mirror, a diffractive element, and a Fresnel reflector.

13. The steerable display system of claim 10 wherein:

the steerable display has a monocular field of view of at least 1 degree, positioned within a scannable field of view of at least 20 degrees.

14. The steerable display system of claim 10, further comprising: an actuator to move the steerable element, the actuator comprising one of a piezo-electric element, a magnetic element, a nanomotor.

15. The steerable display system of claim 14, wherein the actuator has an absolute precision of +/- 0.75 arc minute, and a relative precision of 0.06 arc minute.

16. The steerable display system of claim 14, wherein a settling time is less than 2 ms.

17. The steerable display system of claim 10, wherein the steerable element is a mirror having a diameter between 5mm and 15mm.

18. The steerable display system of claim 10, wherein the position element is smaller than 5 mm x 12mm x 12 mm.

19. A steerable display system comprising:

a display element;

two pivots around which the display element can move in all directions;

piezo-electric elements to drive the pivots, to move the display element; magnets and associated magnetic sensors to determine a position of the display element;

wherein a position of the magnets counterbalances the piezo electric

elements, such that the display element is balanced in weight.
