Eye-tracking systems and methods utilize transparent illumination structures having a plurality of IR μLEDs distributed with a predetermined pattern within the transparent viewing area of illumination structures. The μLEDs are small enough that they are not visible by a user during use of an HMD or other mixed-reality device, for example, such that they can be positioned within the line-of-sight of the user through the illumination structure and without visibly obscuring or interfering with the user's view of the mixed-reality environment by the mixed-reality device.

Method for manufacturing a microLED based illumination structure comprising infrared micro light emitting devices

Eye-tracking systems and methods utilize transparent illumination structures having a plurality of IR &#x3bc;LEDs distributed within the transparent viewing area of illumination structures. The &#x3bc;LEDs are small enough (&#x3c;100 &#x3bc;m) that they are not visible by a user during use of an HMD or other mixed-reality device, for example, such that they can be positioned within the line-of-sight of the user through the illumination structure and without visibly obscuring or interfering with the user's view of the mixed-reality environment by the mixed-reality device.
