Post-Script: I won't claim to be an expert on experimental psychology or crossmodal research, so I must take the good doctor's word on it, with the caveat that I also have my own experience with the Camera Cerebrum to fall back upon.
I must admit that, given the opportunity to go out onto the street, or into the wilds, equipped with either a Camera Cerebrum viewing frame or conventional recording camera, I'm more likely to choose the latter over the former, if given but one choice. In this regard, I seriously doubt that the use of viewing frames will ever become a popular activity unto itself however pleased I might be to see that happen. I am again reminded that a picture, as it is said, is worth a thousand words.
I do find it interesting how the 2nd-generation device has entirely given up its former status of pretend-camera, no longer functioning as a tool to equip the fledgling street-protestor, but instead takes on some hybrid variation of a pretend-tablet device. So it has that going for it.
