Benefits of technology

[0049] the virtual retinal display accounts for any occlusions that at least partially obscure the user's view of the perceived location of the vir

Problems solved by technology

It has the disadvantage that it is typically bulky and has a narrow field of view, and typically provides poor depth cues (i.e. a sense of depth or the distance from the eye to an object).
It has the disadvantage that registration between the real world and the virtual imagery is difficult to achieve without intrusive calibration procedures and sophisticated eye tracking.
A HMD often relies on inertial tracking to maintain registration during head movement,

Embodiment Construction

[0109] As discussed above, the invention is well suited for incorporation in the Assignee's Netpage system. In light of this, the invention has been described as a component of a broader Netpage architecture. However, it will be readily appreciated that augmented reality devices have much broader application in many different fields. Accordingly, the present invention is not restricted to a Netpage context.

[0110] Additional cross referenced documents are listed at the end of the Detailed Description. These documents are predominantly non-patent literature and have been numbered for identification at the relevant part of the description. The disclosures of these documents are incorporated by cross reference.

Abstract

An augmented reality device for inserting virtual imagery into a user's view of their physical environment, the device comprising: a display device through which the user can view the physical environment; an optical sensing device for sensing at least one surface in the physical environment; and, a controller for projecting the virtual imagery via the display device; wherein during use, the controller uses wave front modulation to match the curvature of the wave fronts of light reflected from the display device to the user's eyes with the curvature of the wave fronts of light that would be transmitted through the device display if the virtual imagery were situated at a predetermined position relative to the surface, such that the user sees the virtual imagery at the predetermined position regardless of changes in position of the user's eyes with respect to the see-through display.
