My notes on AR

Concepts

VAS3K, as usual, has an awesome post on AR.

AR vs VR vs MR vs IRL

AR Cloud

SLAM - Simultanious Location and Mapping

Location and Mapping

IMU - Inertial Measurement Unit

Where you are with a combo gyroscope and acceleromater

VIO - Visual Inertial Odometry

Figuring out where you by combo vison and intertial sensores

6 Dimensions X,Y,Z, Yaw, Pitch, Roll

Need to know where your device is in 6 dimensions, X,Y,Z and then rotation Pitch, Yaw, Roll

Y,P,R:

An aircraft in flight is free to rotate in three dimensions: yaw, nose left or right about an axis running up and down; pitch, nose up or down about an axis running from wing to wing; and roll, rotation about an axis running from nose to tail. The axes are alternatively designated as vertical, transverse, and longitudinal respectively. These axes move with the vehicle and rotate relative to the Earth along with the craft.

The Matrix - Simulation

Funny quote from Elon Musk about being in a simulattion.

If you assume any rate of improvement at all then games will become indistinguishable from reality,” Musk said. “Even if that rate of advancement drops by a thousand from what it is now, let’s just imagine it’s 10,000 years in the future, which is nothing on the evolutionary scale.” Given that we’re on that trajectory and that these games are increasingly playable on any device, Musk said, the odds that we are living our lives in base reality — that is, “real” reality — is one in billions.

Why is IRL better then VR

I think the big philosiphical question, especailly for AR, is why be IRL? After all, IRL is just nicer.
