Apple’s hotly anticipated augmented reality headset will be bristling with cameras to enable a range of advanced AR experiences, biometrics and more, according to well-connected analyst Ming-Chi Kuo.

Kuo in a note to investors on Tuesday predicted Apple to integrate a total of 15 cameras in an AR/MR headset rumored to launch in 2022. By comparison, existing VR hardware typically integrates between two and five cameras for interacting with the surrounding environment and performing image pass-through operations.
