CLAIMS

What is claimed is:

1. A system, comprising a computer programmed to:

determine a first horizontal axis of a plane of a display based on a user input; collect angular movement data of the display;

determine a second horizontal axis of the plane of the display based on the angular movement data; and

map a second user input on the display based on the second horizontal axis.

2. The system of claim 1, wherein the computer is further programmed to determine a rotation angle based on the angular movement data and to determine the second horizontal axis based on the rotation angle.

3. The system of claim 2, wherein the computer is further programmed to determine the rotation angle based on an angular speed about an axis normal to the plane of the display.

4. The system of claim 1, wherein the computer is further programmed to project a straight line on the display based on the user input and to determine the first horizontal axis based on an angle defined between the straight line and a predetermined horizontal axis.

5. The system of claim 1, wherein the computer is further programmed to, upon detecting angular movement of the display, determine the second horizontal axis of the plane of the display.

6. The system of claim 5, wherein the computer is further programmed to, upon detecting additional angular movement of the display after determining the second horizontal axis, determine a third horizontal axis based on the additional angular movement.

7. The system of claim 1, wherein the computer is further programmed to determine a vertical axis perpendicular to the second horizontal axis.

8. The system of claim 7, wherein the computer is further programmed to determine the vertical axis based on the second horizontal axis and an axis normal to the plane of the display.

9. The system of claim 8, wherein the computer is further programmed to, upon receiving the second user input, map the second user input based on the second horizontal axis and the vertical axis.

10. The system of claim 1, wherein the computer is further programmed to actuate a component in a second device based on the second user input.

11. A method, comprising:

determining a first horizontal axis of a plane of a display based on a user input; collecting angular movement data of the display;

determining a second horizontal axis of the plane of the display based on the angular movement data; and

mapping a second user input on the display based on the second horizontal axis.

12. The method of claim 11, further comprising determining a rotation angle based on the angular movement data and determining the second horizontal axis based on the rotation angle.

13. The method of claim 12, further comprising determining the rotation angle based on an angular speed about an axis normal to the plane of the display.

14. The method of claim 11, further comprising projecting a straight line on the display based on the user input and determining the first horizontal axis based on an angle defined between the straight line and a predetermined horizontal axis.

15. The method of claim 11, further comprising, upon detecting angular movement of the display, determining the second horizontal axis of the plane of the display.

16. The method of claim 15, further comprising, upon detecting additional angular movement of the display after determining the second horizontal axis, determining a third horizontal axis based on the additional angular movement.

17. The method of claim 11, further comprising determining a vertical axis perpendicular to the second horizontal axis.

18. The method of claim 17, further comprising determining the vertical axis based on the second horizontal axis and an axis normal to the plane of the display.

19. The method of claim 18, further comprising, upon receiving the second user input, mapping the second user input based on the second horizontal axis and the vertical axis.

20. The method of claim 11, further comprising actuating a component in a second

device based on the second user input.
