Katrina,
The use of the video cam glasses is quite limited becasue the video product is negatively influenced by the wearer moving his/her head. Viewers have reported sensations akin to motion sickness. They are good for drive-thrus or locations, like car rental counters, where counter height can block the view of the target for a button cam. The body mounted button camera is needed for shops like new homes, apartments, new cars, assisted living, etc., where the shopper needs to be able to keep the target on camera while turning the head to look as something that is being pointed out across the room, etc. In addition, longer shops tend to require that the camera be blocked when the shopper encounters a reflective surface that would risk putting the shopper's image into the video. Shoppers learn to be proactive about covering the cam before enntering bathrooms in apartment shops, or elevators that may have mirrored walls. Whi;e glasses mounted cam can be redirected in those instances, all of that head swiveling just makes for mor dizzying video; and, of course, just covering the cam with one's hand or a brochure is not very practical, lol.
That said, I suppose that the new video training group that is offering training at the IMSC conferences and at a feew other venues in 2014 can probably help you to learn both methods. For more info check out VSN [

Most of what you need to know when doing long format video shops (15 minutes or more of one-on-one interaction on camera) is NOT about the technology; it's about having scenarios, back stories and unique follow-up info that will conceal your identity effectively and techniques for keeping the target framed in the scene a very high percentage of the time.
