Augmented reality smart glasses work in four simple steps:
The camera or HMD scans and captures part of the user’s real-world environment.
Then, the sensors in the device scan the captured data and identify the points where 3D computer-generated content is to be overlaid.
Next, the device requests a pre-defined 3D environment generated digitally or pre-loaded to the app or device.
Finally, the augmented reality glass would compile, produce and display the finished image with 3D content overlaid on the real-world view as seen by the user.
