Google's 2013 Glass was its own words a small display cube

What you see

By April 2013, Google was shipping Glass Explorer Edition units to the developers who had reserved them, and the company’s own help pages from that month describe what a wearer actually sees: ‘the plastic cube that enters you into the world of Glass. The display shows you a vast amount of information from the current time, to your emails, pictures, video clips, search results, and much more.’ The same help pages instruct a new user to ‘squeeze the nose stem to position the display above your eye and not in front of it,’ confirming the image sits in the wearer’s upper peripheral vision rather than covering the center of their view. A companion marketing page from the same period frames the device around voice commands, hands-free photos and ‘directions right in front of you,’ not around any floating or room-visible imagery.

How it works

Google’s own 2013 description names the display component as a small ‘plastic cube,’ language consistent with a prism-based optical combiner mounted above one eye rather than a projector, waveguide, or free-space emitter. Neither of the archived 2013 pages uses the word ‘hologram’ or ‘holographic’ anywhere in describing the device. A later tech-specs page for the unrelated successor product, Glass Enterprise Edition 2, continues that vocabulary, listing the optics simply as a ‘640x360 Optical Display Module’ — the same plain, non-holographic terminology Google used from the start.

Viewing conditions and limits

Google’s help documentation ties image quality to physical fit: the nose stem and hinge must be adjusted ‘until you can see the whole screen,’ meaning the display is fully legible only from one eye position, set by the wearer at setup. Nothing in the cited pages claims the display is visible to anyone but the wearer, and nothing gives a field of view, brightness, or viewing distance beyond ‘above your eye.’ The 2013 Explorer units were also distributed only to developers who had separately reserved one, not sold as a retail product at that time.

What it is not

Google Glass is not a hologram or a waveguide combiner of the kind this guide documents in headsets such as HoloLens; its own 2013 material describes a small prism-like cube producing a fixed heads-up display positioned to one side of the wearer’s vision, closer in kind to a miniature monitor than to any interference-recorded or light-field image. The company’s own silence on the word ‘hologram’ across every cited page is itself evidence of how the device was actually described at the time.

• Does the display sit inside the wearer’s central vision or off to one side, as Google’s own fitting instructions describe?
• Is the optical component named as a projector, waveguide, or a simple prism or cube, in the manufacturer’s own words?
• Was the device sold broadly at launch, or distributed to a limited group of reserved developers, as Explorer Edition was?

Google’s own 2013 vocabulary for Glass — a plastic cube, a display positioned above the eye — describes a modest fixed-position heads-up display, not a hologram, and the company never claimed otherwise in the pages examined here.
