Abstract

This paper presents the design and the evaluation of a novel wearable see-through display which provides imaging being nearly independent from the eye’s accommodation. This means, that the overlaid display data are perceived to be in-focus independent of the distance the eye is focusing at, making the see-through mode much more convenient in use. The display is based on the direct projection of a miniature LCD onto the user’s retina in combination with the use of partially coherent light to further improve the display’s defocusing properties.

The paper discusses the display concept and presents various experimental results for verification. Finally, a compact and lightweight design for an unobtrusive integration into normal spectacles is proposed.
