Disparity sensor for closed-loop active dimming control, and systems and methods of use thereof

A method of active-dimming control for augmented-reality glasses, the method comprising:

• while a user is wearing augmented-reality glasses:
• obtaining first light information measured via a first sensor positioned to receive light after it travels through a dimmable element of the augmented-reality glasses;
• obtaining second light information measured via a second sensor positioned to receive light that has not travelled through the dimmable element of the augmented-reality glasses;
• and
• actively adjusting a dimming level of the dimmable element based on a comparison between the first and second light information.

A head-wearable device, comprising:

• one or more sensors;
• one or more imaging devices;
• two lenses;
• memory, including instructions for performing one or more operations;
• and
• one or more processors configured to execute the instructions to cause the performance of:
• while a user is wearing augmented-reality glasses:
• obtaining first light information measured via a first sensor of the one or more sensors positioned to receive light after it travels through a dimmable element of the augmented-reality glasses;
• obtaining second light information measured via a second sensor of the one or more sensors positioned to receive light that has not travelled through the dimmable element of the augmented-reality glasses;
• and
• actively adjusting a dimming level of the dimmable element based on a comparison between the first and second light information.
