I am in a situation where I am a participant in taking selfies. I can take them if I must but they are not my preferred form of photography. Yes, human expression can be interesting but I know what I am feeling and do not need to capture it in pixels. However, a large part of the rest of the world in particular my fiancee believes differently. The basic procedure of taking a selfie is something like

1. Find the right background.
2. Figure out your pose and angle.
3. Move your arm to get the “right” angle.
4. Smile or adjust your facial expression.
5. Take the picture.

There is a variation in the above procedure where you find another random human to take the picture. The problem of course is that given that it is only you and perhaps one other person, you can’t slack off and hope for the group to compensate for your photogenic shortcomings. Facing the camera is also rather important. Yes, the old sighted technique of moving your head in the right direction works but keeping there is another matter. No, this is not the blindness thing where some blind people keep moving their head. This is about looking relaxed and being relaxed at the crucial moment when the picture is taken.
The vOICe is handy to have. If I have it running and am wearing my Vision 800 glasses, I can see the camera to focus on. So, there is no need for anyone to position my head and I can keep my neck muscles relaxed. I can correct drift and if the picture is taken when I know I am incorrectly aligned with the camera, I can ask for a retake instantaneously.
