Abstract
Methods, apparatus, and computer-readable media are described herein related to a virtual monitor display technique for augmented reality environments targeted at allowing a user of a display-enabled computing device to substitute their conventional hardware-realized display screen with a virtualized display screen of equal or better usability characteristics than the hardware-realized device. A virtual screen is rendered via a micro display in an augmented reality environment to a human user wearing a see through head mountable device. The system architecture makes use of liquid lens technology in order to adjust the relative position of the display as well as the focal distance by optical means only thereby ensuring that the virtual screen is rendered at the maximum resolution of the micro display at all times. The system architecture also comprises an occlusion matrix thereby ensuring that the virtual screen is free of ghosting. The system is configured in such a way that a display auto-hide function is triggered whenever certain threshold parameters are exceeded. The virtual monitor display technique described herein has been designed with the aim of reducing the effects simulator sickness during prolonged use of the virtual display.

9. A method for enabling a user of a see through head mountable device to be presented with a virtualized display screen, the method comprising:
-
displaying a mostly opaque virtualized display screen to a user of a display-enabled device by means of retinal projection; and in response to an action by the said user, adjusting a plurality of at least one property of the virtualized display screen in such a way that the said user visually experiences the said virtualized display screen in a similar way to a stationary, non-virtualized display screen. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A nontransitory computer-readable medium on which are stored program instructions that, when executed by a processor, cause the processor to perform the operations of
presenting a virtualized display screen to a wearer of a see through head mountable device, and controlling a liquid lens in such a way that an image of the said virtual display screen is altered in such a way that the said wearer of a see through head mountable device can experience the subjective impression of the said virtual screen being a stationary real-world object.
