* Virtual reality is about an other reality. Not like the actual reality that surround you.
* Virtual reality is close to the scope of entertainment because it can display any reality even the fixtuous ones. Out goes from the realty displays in game. Level game. For games. Even gtav. We can imagine how the actual movie industry could use vR to display a new kind of movie
* Augmented reality is about modifying our reality. The current works we live in. It is a way more profound change.
* AR is more about utilities. VR is more about entertainment
* Just trying to better understand the meaning of those words. Those concepts are very young. Their definitions is still very vague.
* How to display it. Where is the screen for the user. Is there a single screens? Or two, one for each eye. Is it see thru display. Is it more normal opaque screen. Can user perceive depth
* Relation between screen position and the latency issue to fool the brain
* What reality is displayed? What is the type  of content. Is it purely virtual or is it our current reality with a little bit on top
* How to interact with this reality? Joypad, depth sensors like kinect or leap motion. Keyboard. Issue of opaque display... You don't see your hands so simple thing like topping on a keyboard is directly very hard when you wear and oculus
* Is it mobile? Gear vr, Google cardboard are mobile. Oculus is not. Leap motion is not. Likely his to be in the future?
* classify each existing devices. It will helps clarify all those concepts
* Augmented reality minimal devices is surprisingly simple to produce. It is in fact very reachable with current technology. Something like tango phones. TODO opaque screen,  depth sensors. Depth sensor is the newest. Kinect has been doing it for years. Leap motion is more recent but still is 2 years old. Now everybody seems to move in this direction
* What about a device like an iPad but with see thru screen. With some strong padding around the screen. Like iPad safe ghetto cover. The batteries and other hardware hidden in the handles. Style isn't too classy but it fits the utility look. And it is robust so for yet another utility requirement.
* augmented reality is a lot easier when it comes to latency. Augmented reality content is likely something small in the middle of current reality. It allows seethru screen. No strong requirement on latency.
* Performence like 15 fps is usable in this specific context.
