Claims

1-30. -30. (canceled)

31. An Apparatus configured to:

receive depth motion signalling associated with depth motion actuation of a physical stylus; and

generate image data of a virtual stylus which has a virtual length according to the received depth motion signalling.

32. The apparatus of claim 31, wherein the apparatus is configured to further receive one or more of translational motion, rotational motion and angular motion signalling associated with respective translational, rotational and angular motion of a physical stylus, and generate image data of a virtual stylus which has one or more of a virtual translational, rotational and angular orientation according to the received signalling.

33. The apparatus of claim 31, wherein the apparatus is configured to generate image data of a virtual stylus on a virtual scene, the virtual scene comprising one or more virtual items which can be manipulated by changes in motion signalling.

34. The apparatus of claim 33, wherein the changes in motion signalling comprise changes in one or more of depth motion, translational motion, rotational motion and angular motion signalling.

35. The apparatus of claim 33, wherein manipulation of the one or more virtual items comprises one or more of the following:

selecting, pushing, pulling, dragging, dropping, lifting, grasping and hooking one or more of the virtual items.

36. The apparatus of claim 31, wherein the apparatus is further configured to receive viewing angle signalling associated with an observer viewing angle with respect to a display for the image data, and generate corresponding image data of a virtual stylus on a virtual scene according to the received viewing angle signalling.

37. The apparatus of claim 31, wherein the apparatus is further configured to receive viewing angle signalling associated with an observer viewing angle with respect to the physical stylus, and generate corresponding image data of a virtual stylus on a virtual scene according to the received viewing angle signalling.

38. The apparatus of claim 36, wherein the apparatus is configured to provide image data of a virtual scene according to the observer viewing angle.

39. The apparatus of claim 31, wherein the physical stylus is in physical contact with a display for the image data.

40. The apparatus of claim 39, wherein the display is a touch display comprising one or more of the following technologies:

resistive, surface acoustic wave, capacitive, force panel, optical imaging, dispersive signal, acoustic pulse recognition and bidirectional screen technology.

41. The apparatus of any of claims 31 wherein the physical stylus is not in physical contact with a display for the image data.

42. The apparatus of claim 33, wherein the apparatus is configured to provide image data for displaying the virtual stylus and virtual scene as three-dimensional images.

43. The apparatus of any of claim 33, the apparatus comprising haptic technology configured to provide tactile feedback to a user of the physical stylus when the virtual stylus interacts with the virtual scene.

44. The apparatus of claim 43, wherein the virtual scene comprises two or more regions, each region configured to interact differently with the virtual stylus, the haptic technology configured to provide different feedback in response to interaction of the virtual stylus with each of the different regions.

45. The apparatus of claim 31, wherein the apparatus is selected from the list comprising a user interface, a two-dimensional display, a three-dimensional display, a processor for the user interface/two-dimensional display/three-dimensional display, and a module for the user interface/two-dimensional display/three-dimensional display.

46. An Apparatus configured to:

generate depth motion signalling associated with depth motion actuation of a physical stylus; and

provide the depth motion signalling to allow for generation of image data of a virtual stylus which has a virtual length according to the generated depth motion signalling.

47. The apparatus of claim 46, wherein the apparatus is configured to generate depth motion signalling based on pressure applied to the physical stylus.

48. The apparatus of claim 47, wherein the pressure is radial pressure.

49. The apparatus of claim 46, wherein the apparatus is configured to generate depth motion signalling based on changes in length of the physical stylus.

50. The apparatus of claim 49, wherein the depth motion signalling is based on changes in telescopic length of the physical stylus.
