In common with most of today's VR headsets, they are relatively large and somewhat boxy; you wouldn't be able to wear the Oculus Quest in public (if you could get your hands on one) without attracting attention. However, HTC seems to be aiming for something a bit more stylish with Project Proton.

As explained to Engadget, "Project Proton is a prototype for HTC Vive's future XR glasses-type device, and we expect feedback from the community as we continue to develop the product."

In the eyes of HTC CEO Yves Mytle, the prototype headset seems "really, really close to regular glasses."

Such a statement is not surprising given that Mr. Meitre is a former CEO of HTC. However, the rendered images shared by HTC look like goggles and are clearly different in appearance from a headset like the Vive.

Currently, HTC is experimenting with two form factors. One of them is a self-contained design, meaning that the necessary hardware is already built into the unit. As shown at the top, that version of the Proton connects the headset to a cushioned module on the back, presumably with the CPU, GPU, and other necessary hardware present.

Then there's this: [This version of Proton needs to be powered by an external device, whether tethering to a PC or connecting to a smartphone. Overall, the design is similar, but unlike the other prototype, the speaker is not immediately visible. Perhaps you will have to provide your own earphones.

HTC has not shared any specifications so far, probably because nothing has been finalized yet. However, according to The Verge, both prototypes use pass-through video rather than transparent waveguide lenses. In other words, you'll be staring at a VR-style screen with virtual elements placed on top of a live image. It's like augmented reality or mixed reality.

The general form factor will probably remain the same, but that could change.

"We hope to move to (normal looking) glasses at some point. We just want to show that we are committed to this journey, that we are invested in this journey, and that we have the first product."

Most of the specifications have yet to be revealed, but according to Input, both headsets will use microdisplays. This has the advantage of being lightweight, potentially allowing for a more compact design.

There is plenty of time to speculate, as HTC plans to release something based on these prototypes within the next few years.
