Technological Refinements

Having discussed my project in further detail with Cornelia I came to the conclusion that the Peep-hole would be physically comprised of an earpiece, a contact lens and a single ring. With the introduction of the contact lens the second ring became redundant as the holographic imagery would be projected by the lens, not between the rings. The purpose of the ring is now to act as a wireless trigger to activate the lens as it would emit the magnetic field necessary for the wireless power. This would maintain the novelty action of the 'peep-hole' but no longer limits users to that particular motion. It's also a lot easier to find a singular ring that fits, opposed to an index and thumb ring that do.
I did some designs for menu layouts for the upcoming interim submission and found a cool motif that I could incorporate into the general design;

Considering the peep-hole is a heavily visual interface I like the idea that menu screens would subtly resemble eyes. They would be centred around a 'pupil', the tabs of the menu being the 'iris'. When shifting between menus a line of light would swipe down the screen and erase the current menu, then swipe the other way to reveal the new menu, effectively 'blinking' between menus.
