Abstract

The invention provides an image generating system and method that provides to an observer a substantially real-time mixed reality experience of a physical work space with superposed thereon a virtual space comprising virtual objects and allows the observer to manipulate the virtual objects in the virtual space by actions performed in the physical work space, and a program for implementing the method and a storage medium storing the program for implementing the method.

Claims

1-19. -19. (canceled)

20. An image generating system for allowing an observer to manipulate a virtual object, comprising image pickup means for capturing an image of a physical work space, virtual space image generating means for generating an image of a virtual space comprising the virtual object, composite image generating means for generating a composite image by synthesising the image of the virtual space generated by the virtual space image generating means and the image of the physical work space outputted by the image pickup means, display means for displaying the composite image generated by the composite image generating means, a manipulator for manipulating the virtual object by the observer, and manipulator pose determining means for determining the pose of the manipulator in the physical work space, characterised in that the system is configured to transform a change in the pose of the manipulator in the physical work space as determined by the manipulator pose determining means into a change in the pose and/or status of the virtual object in the virtual space, wherein the pose of the manipulator in the physical work space is wholly or partly determined from the image of the physical work space outputted by the image pickup means, and wherein the manipulator comprises a recognition member and wherein the recognition member is recognised in the image of the physical work space by an image recognition algorithm, and wherein the appearance of the recognition member in the image of the physical work space is a function of the pose of the recognition member relative to the image pickup means.

21. The image generating system according to claim 20, wherein the pose of the manipulator in the physical work space is at least partly determined by measuring acceleration exerted on the manipulator by gravitational forces and/or by observer-generated movement of the manipulator.

22. The image generating system according to claim 21, wherein the manipulator comprises an accelerometer.

23. The image generating system according to claim 20, wherein the manipulator is connected to an n-degrees of freedom articulated device.

24. The image generating system according to claim 20, wherein a change in the pose of the manipulator in the physical work space causes a qualitatively, and preferably also quantitatively, identical change in the pose of the virtual object in the virtual space.

25. The image generating system according to claim 20, wherein a virtual cursor is generated in the image of the virtual space, such that the virtual cursor becomes superposed onto the image of the manipulator in the physical work space outputted by the image pickup means.

26. The image generating system according to claim 20, which is mountable on a standard working area such as a desktop.

27. The image generating system according to claim 20, wherein the image pickup means is configured to capture the image of the physical work space substantially at an eye position and in the direction of the sight of the observer and the virtual space image generating means is configured to generate the image of the virtual space substantially at the eye position and in the direction of the sight of the observer.

28. The image generating system according to claim 20, wherein the image pickup means is configured such that during a session of operating the system the location and extent of the physical work space does not substantially change.

29. The image generating system according to claim 20, wherein the display means is configured such that during a session of operating the system the position and orientation of the display means does not substantially change.

30. The image generating system according to claim 20 configured to provide a stereoscopic view of the physical work space and/or the virtual space, preferably both.

31. The image generating system according to claim 20, wherein the system is adapted for network applications to accommodate more than one observer.

32. The image generating system according to claim 20, wherein the physical work space captured by the image pickup means is remote from the observer.

33. An image generating method for allowing an observer to manipulate a virtual object, configured to be carried out using the image generating system as defined in claim 20, the method comprising the steps of obtaining an image of a physical work space, generating an image of a virtual space comprising the virtual object, generating a composite image by synthesising the image of the virtual space and the image of the physical work space, and determining the pose of a manipulator in the physical work space, characterised in that a change in the pose of the manipulator in the physical work space is transformed into a change in the pose and/or status of the virtual object in the virtual space.

34. A program and a computer-readable storage medium storing said program, wherein the program is configured to execute an image generating method for allowing an observer to manipulate a virtual object, configured to be carried out using the image generating system as defined in claim 20, the method comprising the steps of obtaining an image of a physical work space, generating an image of a virtual space comprising the virtual object, generating a composite image by synthesising the image of the virtual space and the image of the physical work space, and determining the pose of a manipulator in the physical work space, characterised in that a change in the pose of the manipulator in the physical work space is transformed into a change in the pose and/or status of the virtual object in the virtual space.

35. A method of using the system as defined in claim 20, for visualisation, manipulation and analysis of virtual representations of objects or for data analysis.

36. A method of using the system as defined in claim 20, in medicine, drug discovery and development, protein structure discovery, structural science, materials science, materials engineering, prospecting, product design and development, engineering, architecture, nanotechnology, bionanotechnology, electronic circuits design and development, teleoperations, simulation of extraterrestrial environments or conditions, sales and other presentations and demonstrations, systems biology, finance, economy, entertainment or gaming.

37. A method of using the program or medium storing said program as defined in claim 34, for visualisation, manipulation and analysis of virtual representations of objects or for data analysis.

38. A method of using the program or medium storing said program as defined in claim 34, in medicine, drug discovery and development, protein structure discovery, structural science, materials science, materials engineering, prospecting, product design and development, engineering, architecture, nanotechnology, bionanotechnology, electronic circuits design and development, teleoperations, simulation of extraterrestrial environments or conditions, sales and other presentations and demonstrations, systems biology, finance, economy, entertainment or gaming.
