From comments here, reactions and the obvious fact that none of the killer apps listed use the eye-level camera, I have to assume that putting that tiny hole next to the eye was a big mistake. People go used to cameras pinholes (because those go in your pocket) even their webcam (because they control it) but that one… doesn’t see to go. Narrative (formerly Memoto) develops a similar pinhole: a clip-on camera meant to be worn all day long. It offers a lot of the benefits that people list (record keeping for legal or personal archives); they might need a button to snap, but they face none of the backlash Google has, while they record a lot more. Their product is much easier to ignore, because it doesn’t sit on your face. Google could rapidly solve that by adding in the angle of Glass a collapsible pane, a tiny plastic shield that would swipe away & reveal, then back in front of & hide the pinhole; it could even act as a button for most of the camera action.
