This would be a video headset display like Google Glass, except that it would only be a display peripheral tethered to a phone, without any standalone processing capability of its own.
The video display glasses would communicate with the smartphone by using body network communication, where the signal
passes through your own flesh to connect the phone to the headset peripheral. This type of signal provides high bandwidth and uses less power compared to wireless bluetooth communication.
The smartphone itself would be equipped with a small touch display, to allow you to use it normally like a regular smartphone. However, as soon as you put on the visor, the phone and headset will sense each other's signal, causing the phone's own display to switch off and the video display signal being re-reouted to the video headset. You can still use the touchscreen on the phone like a mousepad for interactive input, but the video output gets displayed on the video headset display. Taking off the headset cuts the signal and resumes the normal smartphone mode.

I would guess that it's possible to send high-
frequency signals through the body pretty easily.
For lower frequencies, I'd say you need some kind of
reference (ground), but for high frequencies I think
there's a brachiaundulic explanation for how they
might be carried without a ground. |
|

"No it doesn't, you just made that up." |
|
| |
Nope, Ericsson is a pioneer in doing R&D on this technology, and it really works. |
|
| |
Hmm, so someone can run man in the middle wossername, so long as they are touching your skin? |
|
| |
Possibly digitally, or perhaps one of them extensible car aerials with conductive gel on the end. |
|
| |
I think the idea of transmitting high-frequency
signals via human skin is well-known and has been
around for quite a while. Basically, humans are
conductors. Not great conductors*, but way
better
than air and quite a lot better than wood. |
|
| |
You don't need conductive gel, or even more than
light skin contact, as long as the thing your
sending the data into has a very high-impedance
input. |
|
| |
(There are some exceptions - Georg Solti springs
to
mind.) |
|
| |
That's kind of a depressing notion.. |
|
| |
It does mean that you need to be carrying the
phone either in contact with your skin, or at a
minimum only with conductive materials between
you and it. This isn't something commonly done. |
|
| |
The glasses would still need the video capability, a
battery, the IO capability, and probably some
processing capability. I have a suspicion that the
net result of all of this wouldn't be that much
smaller/lighter than the original phone. |
|
| |
I'm not saying it wouldn't be useful, but I'm not
sure how useful. |
