video capture with HD eyewear

What are your thoughts about using glasses that are fitted with video capture devices?

Here is one example:

Useless. The sensor is way too small.

How large should the sensor be?

I clicked on this thread because I thought it was about eyeglass monitors fed from the HDMI output of a camera. I certainly could use a set. Anyone have any experience with them?

"eyeglass monitors fed from the HDMI output" Exactly what I want to know.

Some years ago I've tried eyeglasses from Sony (Resolution 640x480) but after 10 minutes I got headaches. Maybe in the meantime the technology has changed?

These zShades HD have a visible jello effect and in the videos there is a huge amount of grain. So they're pretty useless for stock. Unless you capture some very very interesting newsworthy stuff.

I think most people here use HDMI monitors like the Chinese Liliput series: http://lilliputweb.net/ or more expensive USA models.

Mine broke (some gear doesn't like rain) and it was only SD, but helpful, although sometimes because of challenging acrobatics and invasive light, it's hard to see a screen, even with a shade, not to mention hard to put it in a place to view it when doing clips that require dangling oneself and one's camera over the bow rail of a boat.....
