Meta patents headset lights that turn on when cameras can't see your hands
Meta has filed a patent for a mixed-reality headset that uses built-in floodlights to help its cameras track hand movements. The system automatically turns on these lights when the camera images are too blurry or dark to accurately identify gestures, ensuring the headset can still understand your hand positions.
In the filing’s own words
An example MR headset is provided. The example MR headset comprises (i) a set of imaging sensors and (ii) a set of floodlight-emitting diodes (flood LEDs), the sets of imaging sensors and flood LEDs disposed along a front-facing portion of the MR headset. The MR headset includes one or more processors configured to, while the MR headset is being caused to present MR content, and in accordance with a determination that imaging data obtained from the set of imaging sensors has an insufficient level of detail to identify hand gestures, cause illumination, using one or more flood LEDs of the set of flood LEDs, of a volume of physical space that includes the hand of the user.
What exactly they claim (claim 1)
1. A head-mounted device, comprising: (i) imaging sensors and (ii) illumination sources, the imaging sensors and illumination sources disposed along a front-facing portion of the head-mounted device; and one or more processors configured to: determine a user centric reference position associated with a user viewpoint based on a position of the head-mounted device, and define a gesture interaction zone based on the reference position, wherein the gesture interaction zone includes a body part of a user; and in response to a determination that a level of detail associated with detecting a user interaction is below a threshold, cause the illumination sources to illuminate at least a portion of the gesture interaction zone.
