Did I just see what I thought I saw? Wouldn’t it be nice to be able to rewind life by 30 seconds and be able to reply it? Now you can, with these relatively cheap (~$80) eyeglass-mounted cameras. The eventual aim is to have cameras that record, you know, your whole life. I would go for one of those in a second. I wonder what it does to social interaction. Steve Mann would know.
Anyway, far too large, in my opinion. It has advantages over a pinhole camera at the lapel or necktie, in that it follows your line of site, but even if it is lightweight, it is also intrusive. The obvious solution is a fibre optic line, but that’s a big jump in cost.
