Kuo's latest research note on the mixed reality headset, published by MacRumors, states: "Apple's eye tracking system includes a transmitter and a receiver. The transmitting end provides one or several different wavelengths of invisible light, and the receiving end detects the change of the invisible light reflected by the eyeball, and judges the eyeball movement based on the change."
It is Kuo's understanding that Apple is working hard on eye tracking technology because of how current virtual reality headsets rely on handheld controllers that the analyst says don't provide a smooth enough experience.

Kuo says the eye tracking technology will provide a more intuitive user experience, letting the wearer interact seamlessly with their environment. It is also suggested how the headset would reduce the resolution of areas of its display that the user isn't looking at, which in turn could reduce computational burden.
The analyst also suggests that, based on hardware specifications, the headset could feature iris recognition, which could act as a form of biometric security and bring Apple Pay to the headset.
The headset has previously been described by Kuo as portable rather than mobile. It is also thought to be an accessory to the iPhone rather than a standalone device. Despite its accessory status, the headset is thought to carry a high price tag of around $1,000. A such, it will almost certainly be a niche device by Apple's standards, selling in fewer quantities than products like the Apple Watch.
