Carl Zeiss is a company that makes optics, and doesn't work on software. This is only a hardware solution, with no software implementation yet. Currently Carl Zeiss is seeking a software partner, however this will take time for them to develop a complete product once they do find a suitable partner.
The technology used in the Carl Zeiss Smart Glasses project can be transferred to normal glasses, or wherever curved glass is present. This solves the fundamental issue with Google Glass, which required an out-of-place flat piece of glass to function.
The device uses a see-through screen allowing information to be displayed in the wearers general view instead of on the side. Currently the display is capable of displaying information in a monochrome green color at 419x138 pixels, 15 frames per second and up to 1000cd/m2 brightness.
The Epson Moverio glasses can scan real world items such as a QR code to bring up relevant information right ontop of the QR code itself. AR (augmented reality) can also be useful for other technological activities - such as flying a compatible drone in first person view, viewing virtual blueprints, or just casually watching Netflix.
The display tech used is OLED, which means that the display will disappear completely when not in use (OLED doesn't need a backlight for black pixels, while a LCD requires the full backlight to be on even when only a small section of the display is required to be on).
These are clearly smart glasses, and even from a distance it will easily be able to tell. The camera on the right side will mean that you won't be able to wear these glasses everywhere, and in public you'll get more than a few strange looks.
There are 2 ways to control these smart glasses - either through head movements or with a wired controller. While out and about it will be much easier to use the head movements, however at home or when playing games or perhaps web browsing the controller will make for an easier controlling experience.
While they could be used for consumers, they haven't been designed for average consumers. These are meant for businesses - possibly museums, engineering firms, or designers. There may not be much non-enterprise software available for the average user.
Most of the controlling will be done through the wired touchpad. This is a clunky implementation, and requires a wired attachment. It isn't ideal for out-and-about usage, which is what smart glasses excel at.
Because these glasses have their displays right in the middle of your vision, they can project digital images ontop of reality (augmented reality - AR for short). This means you can get contextual data about an item right in your field of view. This tech can be used by interior designers to see how a room would look like with different furnishings in different places, as well as more everyday uses like drawing a navigation line ontop of the road when navigating.
These glasses don't have any ability to be adjusted - this isn't tech you'll be easily be able to share with others while remaining comfortable. It also means that if you normally wear glasses, you will need to wear those under these smart glasses.
