I tried out google glass last fall and this matches my experience of it. It really doesn't overlay info as part of your normal view, which for me removes the AR designation. It does place information in a place that doesn't require you to move your head or look down, which is I guess where the "heads up" description comes in...but it still requires you to divert your attention, like looking at a rear-view mirror in a car. Sure, you can still see things in front of you in your peripheral vision, but that still seems less integrated than I would associate with the term HUD.
