Apple launched the all-new 2020 iPad Pro with  A12Z chipset that is a little more powerful compared to the 2018 iPad Pro. The company also rolled out support for keyboard and trackpad that brings it much closer to actually being called a computer. In terms of hardware, the 2020 iPad Pro received a significant bump in the camera department with an ultra-wide-angle lens and a LiDAR sensor. It is possible that the 2020 iPad Pro's LiDAR sensor is doing all the groundwork for Apple's rumored Apple Glass to enhance the AR experience.

LiDAR sensor is not your everyday camera sensor that aids in capturing photos and videos. It is used in self-driving cars to build a 3D map of surroundings. It can calculate distance, location, and more. The 2020 iPad Pro equips the LiDAR sensor which will mostly perform augmented reality tasks. However, there's a possibility that the iPad's sensor does not solely relate to the device alone.
