I have some interest in Augmented Reality, and after some watercooler discussions, I came up with a short list of features and 'killer apps' for a hypothetical Apple iGlasses device that (a) uses technology available now and (b) provides a number of features that no other product could deliver. The full technical details are here: http://evillabs.blogspot.com/2011_01_01_archive.html#5178217950582099284 Short list of features that the proposed 'iGlasses' platform could do: Mood Snaps - "Never miss another moment" The iGlasses would take a 3D video of the last 15 seconds (adjustable) and following 10 seconds when a 'mood inflection' is sensed. Rapid change in hear rate, changes in vocal stress, very loud noises, changes in skin temperature, etc would be used to compute an 'inflection' point. Users could edit and post these automatically snapped videos at their leisure, or individuals in high risk occupations could have them automatically uploaded to a private location. I would expect this to be the primary driver behind most sales in the first year Optometrist App - "Your prescription is always correct" In fully reflective mode, the iGlasses paints the incoming camera image on the inside of the glasses, and uses the dynamic focusing to automatically correct for the user's nearsighted or farsightedness. For most users with mild correctable vision, they would not need to wear their prescription glasses nor contact lenses while wearing the iGlasses. Hyperreal 3D - "Be There" This feature destroys the 3D television market. By using the laser projected 3D with dynamic focus, the most vivid and comfortable to the eye 3D projection is possible. Combined with 'fully 3D' machinama technologies and the head mounted accelerometers, the user can now 'look around' during 3D movies, for a truly immersive experience. (And a new raft of headaches for the Hollywood editing room!) AR Anywhere The feature that will grow the slowest, but be the real driver of sales after the first year. Augmented Reality video games; 'pop up' labelling of stores, products, (people in bars!); an arbitrarily infinite number of virtual monitors for the workplace; and even more are possible. Huge opportunities for work and play applications, that are impossible for any other platform.
