Our tipster has now seen a prototype and said it looks something like Oakley Thumps (below). These glasses, we heard, have a front-facing camera used to gather information and could aid in augmented reality apps. It will also take pictures. The spied prototype has a flash —perhaps for help at night, or maybe it is just a way to take better photos. The camera is extremely small and likely only a few megapixels.
The heads up display (HUD) is only for one eye and on the side. It is not transparent nor does it have dual 3D configurations, as previously speculated.
One really cool bit: The navigation system currently used is a head tilting-to scroll and click. We are told it is very quick to learn and once the user is adept at navigation, it becomes second nature and almost indistinguishable to outside users.
(As an aside, I built a head mouse as a Masters Thesis project a few years back that used head tilts to navigate and control menus. I am ready to collect royalties!)
I/O on the glasses will also include voice input and output, and we are told the CPU/RAM/storage hardware is near the equivalent of a generation-old Android smartphone. As a guess, we would speculate something like 1GHz ARM A8, 256MB RAM and 8GB of storage? In any case, it will also function as a smartphone.
