My thoughts exactly - the privacy implications of this are huge. I have a visual aid called MyEye that will speak aloud text it 'sees' with a camera when one pushes a button. It works fairly well, but the idea is to attach this thing to one of the arms of a pair of glasses. Aside from not wanting to look like a Borg, it just takes too much energy to explain to concerned strangers that the camera is for text recognition and some very primitive object recognition (like approaching doors). Imagine trying to explain with Apple glasses 'oh yes, and it can take and store pictures'. Paranoid types (like me) would be concerned about control of the device when it is just sitting on a table (phones are usually pocketed when not in use). At a minimum there should be a hard-wired LED that flashes a warning if the cameras on the device are taking pictures (I actually think this should be true of all digital cameras by law). I understand that there is no expectation of privacy in public, but cameras keep getting smaller and so the activity of taking pictures has changed. It used to be if you did street photography it was obvious by the camera, camera bag, and possibly tripod. People could gracefully exit the picture if they saw you setting up. Now you just never know when somebody is taking your photo and frankly it is getting a little creepy, not to mention annoying as tourons in my town stop abruptly on the pavement/side-walks and take photographs of the buildings and monuments, obstructing everybody else's path.
