You can demand that people not wear Google Glass in your home; it is no different than demanding that people not photograph the inside of your home. My college roommate had such a policy: absolutely no pictures of him in our room, and he politely asked that no pictures of him drinking alcohol or being around alcohol be taken. In a public place, you have no such right, with the exception of commercial use of the photo (which requires your permission). A more important concern is whether or not Glass users will be able to choose service providers other than Google. What if Google pulls the plug? What if I want to use Glass in an environment where business secrets might be recorded? That is a far greater issue than the presence of a camera.
