A forgettable near eye display

Beyond the desktop: emerging technologies for supporting 3D collaborative teams

“…To-date, the challenge has been to design a full color (red, green and blue) display based on an HOE. A head-worn, look-at display with a 3 mm exit pupil, 27 × 10 degrees of field of view, operating at the single wavelength of 532 nm was recently designed based on a HOE and fabricated by Minolta [8]. A radical alternative in the design of HWDs is to produce a raster image by scanning the retina with a laser beam, which would be accomplished without intermediary image formation.…”

“…Pupil expanders add additional complexity and size to the system and also reduce perceived brightness, creating in practice unique trade-offs. An alternative to higher luminance sources is to dim the light from the scene using polarizers, or yet more desirable electrochromic or photochromic mechanisms [7][8][9].…”

Dual-element off-axis eyeglass-based display

“…There has been several prototypes in the area of eyeglass-based displays. Example of previous designs include the work by Bettinger[1], Spitzer [2] and Kasai [3]. A comprehensive review of designs in the eyeglass formfactor is provided in [4].…”

ASTOR: an autostereoscopic optical see-through augmented reality system

“…While there have been significant advances in this research area, resulting in increasingly smaller head-worn-displays, such as the displays developed by Minolta [7] and MicroOptical [14], we believe that the area of projection-based AR is fairly unexplored and has great potential in terms of achieving AR with minimal intrusion. This paper presents a novel projection-based AR system with an optical see-through display where a holographic optical element (HOE) is used for autostereoscopy.…”
