RE: Dots or No Dots that is the key question and if no dots where are our dots going to?2 Mar 2024 07:41
That’s a pretty old article I’m sure has been mulled over by many over the past six months since it came out July last year and pretty sure details of exactly how the sensors manage to achieve the performance are not covered..i can’t say it gives more of a clue whether Nanoco materials are involved or not..but does give an idea of quantity per headset that again has been previously discussed.
IR Camera – The presence of an IR camera on any device plays a key role in being able to do the job of a camera when the camera can’t. IR sensors work in absolute darkness too, giving them a significant edge over conventional cameras. That’s why the headset has 4 IR Cameras on the inside, and an undisclosed number of IR cameras/sensors on the outside to help the device see despite lighting conditions. The IR cameras inside the headset do a remarkable job of eye-tracking as well as of building a 3D scan of your iris, to perform Apple’s secure OpticID authentication system.
Illuminators – While these aren’t sensors, they play a key role in allowing the sensors to do their job perfectly. The Vision Pro headset has 2 IR illuminators on the outside that flash invisible infrared dot grids to help accurately scan a person’s face (very similar to FaceID). On the inside, however, the headset has invisible LED illuminators surrounding each eye that help the IR cameras track eye movement, reactions, and perform detailed scans of your iris. These illuminators play a crucial role in low-light settings, giving the IR cameras data to work with.
