Techniques for using floodlight LEDs when imaging sensors have an insufficient level of detail for identifying hand gestures, and mixed-reality systems and methods of using these techniques

A non-transitory computer-readable storage medium including instructions that, when executed by one or more processors of an MR headset, cause the MR headset to perform operations comprising:

• at the MR headset that includes (i) a set of imaging sensors, (ii) a set of flood LEDs, (iii) a display, (iv) memory, and (v) one or more processors, wherein the sets of imaging sensors and flood LEDs are disposed along a front-facing portion of the MR headset:
• while the display is presenting MR content:
• in accordance with a determination that one or more imaging sensors of the set of imaging sensors are capturing imaging data, illuminating, using one or more flood LEDs of the set of flood LEDs, a target-hand interaction zone,
• wherein:
• a virtual-third-eye center position is determined based on a position of the MR headset, wherein the virtual-third-eye center position corresponds to a point between eyes of a user, and
• a volume of physical space is defined based on the virtual-third- eye center position.
