I'm on a computer now, this is much easier. From their site
here:
+ WHAT IS INFINITE FOCUS?
The AR-1's advanced optical system presents an image that is focused to your eye, rather than your eye needing to focus on it. The display allows you to see everything behind and to the sides of you, plus vehicle telemetry and GPS navigation, as fast as your eye can move. This allows you to see the display as an extension of your peripheral vision, and with a quick glance of your eye, you see everything in the display instantly."
I almost purchased a Reevu, which uses a mirror and refraction system to give you a rear view right above your eyebrows inside your helmet, but that seems even worse. First, you have to raise your eyes UP (most hazards are down on the ground), and second, you'd have to adjust your eyes to finding the mirror, then focus on what's IN the mirror.
Since the Skully (aka Google) glass is see-through, you still see everything behind it. It's just an 'overlay' of what you are already looking at, and only in that quadrant of your vision. It's no different than checking your mirrors (actually, it's probably SAFER than checking your mirrors, since you have rear camera vision and can actually move your head around to check for blind spots). Even then, the rear camera has 180 degree vision:
"+ WHAT APPEARS ON THE HEADS-UP DISPLAY (HUD)?
The display shows a rear view camera feed with a near 180 degree viewing angle. This means it not only sees what is behind you, but also what is in your left and right blind spots. The display also optionally shows turn by turn directions. These turn by turn icons are present only when needed, then automatically disappear when not in use. It also optionally, if supported by the motorcycle, may display vehicle telemetry such as speed, gear, tachometer, etc.
+ WILL THE HUD OBSTRUCT MY VISION WHILE RIDING?
No. The display is transparent, and we have positioned it outside the rider's primary field of view where it appears to float in the distance. It appears to be about the size of the rider’s outstretched hand. This means you can see the road ahead without any obstruction from the display. This display system simplifies the riding experience because you no longer need to take your eyes off the road to see what is around you or to find your route. With our optical technology, the display is always in focus no matter where you look, allowing instant comprehension of the information."
I'm pretty excited to get mine. As always, I'll spam the forum with some videos.
