The Fraunhofer Institute has developed what they call Interactive Data Eyeglasses, using OLED projector technology to project data directly onto the wearer’s retina.
The chip measuring 19.3 by 17 millimeters is fitted on the prototype eyeglasses behind the hinge on the temple. From the temple the image on the microdisplay is projected onto the retina of the user so that it appears to be viewed from a distance of about one meter. The image has to outshine the ambient light to ensure that it can be seen clearly against changing and highly contrasting backgrounds. For this reason the research scientists use OLEDs, organic light-emitting diodes, to produce microdisplays of particularly high luminance.
Very Sci-Fi, although they do admit that they don’t have any timeframes for any type of usable product.
