AR Camera GYRO uses the camera and gyroscope on the player’s mobile device to display 2D or 3D objects as though they were in the real world.
All modules are designed independently to keep this asset extendable & easy to understand.
⚡ Cross-platform mobile camera implements markerless augmented reality (AR) by using a gyroscope (like Pokemon GO).

Gyro vs. Accelerometer
90% of all mobile devices have an accelerometer and video camera but only 20% have a gyroscope.

Different devices have different gyroscopes, and therefore different deviations and drifts.
